Systemic Capillary Leak Syndrome

What is Systemic Capillary Leak Syndrome?

Systemic Capillary Leak Syndrome (SCLS) is an exceedingly rare, life- and limb-threatening disorder characterized by acute and severe recurrent attacks featuring a rapid fall in blood pressure due to the temporary leak of plasma out of the blood circulatory system.

This virtual community is dedicated to the memory of Judith (Judy) Lynne Davis (1958-2009) (judithdavis3), one of its founding members and a victim of a very severe episode of SCLS that took her life in November 2009.

We also mourn the death of nine other SCLS patient members of this community: Mario Gatto (mariogatto) from Naples, Italy, who passed away in December 2009; Denise Weston (mdweston) from Ohio, USA, who passed on March 2011; Bruno Galien (bruno) from Nord-Pas-de-Calais, France, who passed away in February 2012; Guy Allen Overland (allenoverland) from the Washington DC area, USA, who passed on January 2015; Marilyn Meaux (maire602) from Louisiana, USA, who passed away in March 2017; Julie Eady (jodono) from Perth, Australia, who passed on September 2017; Cara O'Hagan (Cara) from Dublin, Ireland, who passed away in February 2018; David Colburn (davec) from Gainesville, Florida, who passed on in September 2019; and Jeff Isenhour (jisenhour) from Wahington, DC, who died in September 2021.

Systemic Capillary Leak Syndrome (SCLS) is idiopathic. Thus, at present, there are no known causes. Probably a mid-life gene mutation takes place that renders those affected vulnerable. Possibly immune-deficient in some way to these curiously self-reversing capillary leaks.

Many patients report having a runny nose, flu-like symptoms, gastro-intestinal disorders, a general weakness or pain in their limbs, swelling in the face or hands and feet, or very cold hands and feet, but others get no particular or consistent warning signs.

Name Description
Swelling swelling
Myalgia Myalgia is muscle pain
Rhinorrhea Rhinorrhea is a runny nose
Dizziness Dizziness
Lightheadedness Lightheadedness
Hypotension Hypotension is abnormally low blood pressure
Hemoconcentration Hemoconcentration is the decrease of the fluid content of the blood, with increased concentration of formed elements
Hypoalbuminemia Hypoalbuminemia is low levels of protein in the blood
Nausea Nausea
Excessive thirst Excessive thirst
Generalized edema Generalized edema
Decline in clinical picture Clinical picture declines rapidly within hours
Cold limbs and sweating Cold limbs and sweating
Rapid swelling and compartment syndrome Rapid swelling of all limbs with development of compartment syndrome, especially during IV fluid administration
Decreased urine output Decreased urine output
Vomiting Vomiting
Intestinal cramps Cramps
Diarrhea Diarrhea
Fatigue Fatigue
Headache Headache

The diagnosis of SCLS is made partly by exclusion, namely, by eliminating the possibility of other more common diseases, and is based on measurable, clinical symptoms such as hypotension or low blood pressure, hemoconcentration or decrease in blood volume, hypoalbuminemia or an abnormally low levels of a protein called albumin in urine, and the presence of a protein called Monoclonal Gammopathy of Unknown Significance (MGUS).

Some diagnostic tests may include blood and urine tests to check for abnormalities such as dark urine, concentrated blood, or low serum albumin in the blood.

  • IVIG 1 g/kg twice (two infusions) as soon as possible after arrival at the Emergency Room.
  • Methylprednisolone 125 mg intravenously one time, then repeated as needed.
  • Judicious use of intravenous fluids (IVF) in boluses and drips to keep central venous pressure (CVP) above zero.
  • Phenylephrine or Norepinephrine for hypotension, early institution.
  • 50 ml of 25% albumin, then repeated as needed.
  • Continuous CVP monitoring, immediate (stat) and continuous (serial) lab work including createnine phosphokinase (CPK) and lactate.
  • Immediate orthopedics consult and compartment pressure measurement early on to prevent limb fasciotomies if compartment pressures or CPK are high. 
  • Venous doppler for deep vein thrombosis (DVT) prevention, may need full anticoagulation to prevent blood clotting.

Treatment of an episode of SCLS requires recognition that there are two phases. The first phase, which often lasts 24-72 hours, is called the leak phase.  A plasma and albumin leak from the capillaries into the tissue spaces causes swelling, especially in the muscle compartments of the extremities. The blood pressure falls and the red cells concentrate. This loss of fluid from the vascular system has similar effects on circulation as dehydration, slowing both the flow of oxygen carrying blood to tissues and the output of urine. Physicians should refrain from trying to stop or control the capillary leak except by administering IVIG at the outset, possibly supplemented by injected steroids. Even though blood pressure readings may reach and remain at very low levels, oliguria should be tolerated and aggressive intravenous fluid administration should be avoided, because fluids will mostly leak out and cause compartment syndrome and other complications.

The goal of saline and vasopressors administered should NOT be to restore a "normal" blood pressure (or urine flow), but to maintain it at a minimal level sufficient to avoid permanent damage to vital organs. Measurement of central venous or arterial pressure in an ICU setting is often necessary to achieve this delicate balance. When too much fluid is administered, the result is excessive swelling, and the patient will usually require surgical decompression of the limbs. In this procedure, known as a fasciotomy, the skin of the arms and/or legs is incised to release the compressive pressure the retained fluid is having on blood flow to and from the extremities.

The second phase of the treatment is known as the recruitment phase, when fluids and albumin are reabsorbed from the tissues during at least a couple of days. In this phase, the capillary leak has ended and the main threat is fluid overload. If intravenous fluids were given in excess, they usually cause an accumulation of fluid in the lungs and around other vital organs. Most of the patient deaths happen during this recruitment phase so it is important that diuretics be administered to help patients discharge all the fluid previously given -- and to keep them from backing up, especially into the lungs.

As concerns episode prevention, two approaches have been tried: high-dose β-agonists like theophylline and terbutaline, and a prophylaxis with high-dose intravenous immunoglobulin (IVIG) infusions. In the past two decades, most SCLS patients have been migrated from the former to the latter in Canada, Europe, the United States and beyond, because IVIG therapy leads to far superior results. IVIG infusions every 2 or 4 weeks prevent or minimize leak episodes far more effectively than any other therapy, and do not have the adverse side effects that treatment with high doses of β-agonists like theophylline and terbutaline entails.

The prognosis is uncertain and depends on (a) how well episodes are managed, in terms of preventing permanent damage to vital organs and extremities; and (b) the ability to prevent episodes altogether.

There are two main treatments to prevent episodes of SCLS. The oldest is the Mayo Clinic’s approach of a preventive therapy with theophylline (or aminophylline) and terbutaline tablets taken on a daily basis. However, these medications, meant to reduce endothelial hyperpermeability, have very unpleasant side effects, and often prove ineffective, providing partial and transient improvement.

The newest is the French preventive regimen, which involves monthly infusions of immunoglobulins (IVIG). By now there is ample evidence that IVIG (usually, 1 or 2 gr/kg per month, administered over two consecutive days) has worked for many patients in Europe, the United States, and beyond for over 15 years, thus having become the gold standard of preventive care.

SCLS and Meniere's Created by kevinl1970

Good afternoon, I was looking for a unique way to introduce myself to this fine community as I have also been recently diagnosed with SCLS.  Hopefully this is light at the end of the tunnel after five years of mystery attacks and hospitalizations. I've been told in the past I've possibly had septic shock, heart failure, kidney failure, severe dehydration, polycythemia vera, pneumonia, and many other things I cannot remember at the moment. About six months ago someone in the ER mentioned SCLS and when I read up on it, the symptoms, blood tests, etc. matched up closer than anything before. None of the dr's in my area (a major metropolitan city in the US) would agree to an evaluation, and I eventually ended up at the Mayo clinic. They ruled a few other things out, and here I am, now waiting for my first IVig treatment.

Being a rare disease, I have begun to start to question my diagnosis of Meniere's disease from 30 years ago. To date, I've had two otolaryngologists say "Yes it's Meniere's" and two say "It's definitely NOT Meniere's".  I have issues in both ears, one started when I was 18, the other three years later. The doctors say it's extremely rare to have it in both ears. So did I hit the jackpot of rare diseases or what? 

Some of the recent blood tests I've had indicate problems in my immune system, and one otolaryngologist mentioned it could be an autoimmune disorder causing the Meniere-like symptoms. 

So I guess once I get things stabilized with the SCLS I can re-evaluate on the Meniere's 

Has anyone here had anything like Meniere’s ?  i.e. sudden hearing loss, sudden vertigo, "drop attacks" where you fall due to loss of balance and can't stand up?

Hi Kage101,

I am familiar with SCLS episodes following a covid vaccine, especially tbe J&J one as we have had several cases here in Spain.

Furthermore, these cases are the main reason why my doctors advised me against getting vaccinated.

How is your fiancée coping with her symptoms? Were you able to attain medical assistance regarding her generalized oedema?

I'm so sorry to hear about your fiancée's medical problem!  While I'm not a physician, I've learned a great deal about SCLS during the past more than fifteen years, through this community and from personal experience, and in my opinion she does not suffer from SCLS.  

SCLS is an exceedingly rare episodic illness characterized by acute and severe attacks featuring a rapid fall in blood pressure due to the temporary leak of plasma out of the blood circulatory system.  Patients gain weight during an episode IF they are given replacement intravenous fluids, and then only during a few days.  Once the leak episode ends, and if they survive it, their body gets rid of all excess fluids, and thus their weight returns to normal.

In other words, SCLS features a self-reversing phenomenon.  Therefore, what you are describing, somebody gaining weight week after week, and month after month, is indicative of some other, chronic -- as opppsed to episodic -- swelling disorder.

If you can afford it, or can work out a deal with the hospital in advance, I suggest you make an appointment for her to be seen at the world-famous Cleveland Clinic.  People of means or with good insurance flock there from all over the country and even from abroad with all kinds of undiagnosed or unresolved health problems.

Failing that, your next-best bet (and closest option) is for her to be seen by an edema specialist at the Ohio State University Wexner Medical Center in Columbus, which is ranked #2 in Ohio.  This includes internists (big-picture clinicians), nephrologists (kidney specialists), and gastroenterologists (digestive tract or liver specialists), as well as bariatric (weight control) physicians.  Check out or else

Good luck and keep us posted!

Covid-triggered episodes of SCLS? Created by aporzeca

Hi everyone! I hope you're all doing great. 

Even though this thread is about our experiences contracting Covid, I just wanted to share that I haven't caught it nor received the vaccine. 

I will revisit this thread and share my experience if that happens, however, I really hope I never do, especially when I'm not receiving IVIG infusions because my doctors say that "it's just a patch". I know its controversial, but so far they are currently looking for other ways to treat my chronic leakage.

They also think that it's not safe for me to get the vaccine as it would worsen endothelial hyperpermeability and escalate to a more serious episode. 

Best of health to all of you,

Hi all - hope you are all well.

I didn't exactly have SCLS triggered by covid, but I definitely feel the vaccines triggered symptoms for me and that there was some effect of covid that seemed like SCLS.

I had 2 doses of the Pfizer vaccines in January and February of 2021. I had chronic symptoms of SCLS from that time until October 2021. I told my doctors I had gained weight prior to getting the vaccines and asked them to raise my dose of IViG to match my weight. We conferred with Dr. Druey and he agreed. Once my dose was raised, the chronic SCLS symptoms resolved.

I caught covid around 1/5/22, less than 2 weeks after an IViG infusion. I got over most symptoms in a week, but the exhaustion, lethargy and brain fog lasted until February. Those symptoms felt similar to some of the symptoms I get during an SCLS flare - very heavy, weak, dull, brain-foggy (translate that slang as "stupid"), and lethargic. I can't say I know covid would have been different for me if I didn't have SCLS, but I do kind of feel like that's the case. So no, I did not have a real SCLS flare due to covid, but maybe SCLS influenced how I experienced covid.

Because I had such a miserable time after the vaccines, I don't want to get boosters. I've made significant changes to my life in order to avoid having to do that.

My best wishes for us all, and thanks -

Hi Arturo.  I will take the audacity to write in our mother tongue, and I will put the Google translation at the end.
 Many times I am left wondering how real they are, and I want to make sure that my query was well understood.
 I was not referring to the fact that the technology of the vaccines modifies the coverage capacity for Covid.  But to the possibility that the vaccine, by itself, has a greater possibility of triggering an attack both in the first dose and when changing technology.  I haven't seen a lot of SCLS attacks for the vaccine here on the forum... but I know there are.
 Perhaps because neither North America nor Europe recommend changing brands (is this everyone or just SCLS sufferers?) As always, thank you for your time and dedication.

Hola Arturo. Me tomaré el atrevimiento de escribir en nuestra lengua madre, y pondré la traducción de Google al final. 
Muchas veces me queda la duda de que tan reales son, y quiero asegurarme de que mi consulta fue bien entendida.
No me refería a que la tecnología de las vacunas modifiquen la capacidad de cobertura al Covid. Sino al la posibilidad de que la vacuna,  por sí sola, tenga mayor posibilidad de desencadenar un ataque tanto sea en la primera dosis como al cambiar de tecnología. No he visto aquí en el foro, mucho de ataques SCLS por la vacuna... pero se que los hay. 
Quizas porque ni en América del Norte ni en Europa aconsejan el cambio de marca (esto es a todos o solo a enfermos de SCLS?) Como siempre, gracias por su tiempo y dedicación.

So far, I've only found one study, conducted in Italy, that postulates that chronic dysautonomia may trigger SCLS flares in addition to SCLS triggering temporary autonomic dysfunction.

My physicians are wondering whether my SCLS is triggering autonomic dysfunction [in paricular, daily hypothermia], or whether the hypothermia is triggering mild flairs. Is there any research on the subject of dysautonomia being a cause rather than a symptom  of SCLS?

I would be most grateful for any information, including fellow patients' experiences. I will be seeing an autonomic neurologist at Massachusetts General Hospital in July, but my physicians are very worried about my temps as low as 90.1 three to four times a day, accompanied by rigor & blue extremities, followed by sweating and bright red extremities & face.

Robert, first, and as you know, I’m not a physician, and thus the following does not constitute medical advice. Second, FYI, I’ve never had trouble sleeping before, during, or after my IVIG infusions -- but then, I've never taken steroids in conjunction with my infusions.

If I were you, I would discuss the following options with your physician. The first is to reduce or possibly eliminate your intake of steroids, because one of their best-known side effects is that they cause nervousness, anxiety, and insomnia, see, e.g.,,daily%20dose%20in%20the%20morning and

Therefore, what you are experiencing is unlikely to be a coincidence. Maybe there was a good reason, long ago, for you to take steroids in conjunction with your infusions, but our bodies change over time, so it’s possible that your body doesn’t need those steroids anymore, or not as high a dose of them. Indeed, your having insomnia now may be a signal your body is sending you that it doesn’t want those steroids in your system!

The second option is for you to take a sleeping pill, or something else that will relax you and let you sleep, on those nights after your infusions. Your physician might prescribe you a sleeping medication or tell you to take some Benadryl. He/she probably won’t advise you to take a shot of your favorite alcoholic drink, but that's what some of us do when we have an occasional problem falling asleep!

Good luck!

Thank you for your help with the Doctor referrals. I really appreciate it. You have always been a wealth of resources to me through the years. I tried to send you a private message prior to going to the doctor but it apparently did not go through. I see him again this week. I would loove to take you up on your offer to have you forward the articles to my email (Shannoncdowell AT gmail DOT com) . Thank you so much 


I have a question for you wondering if you have run in to anyone or heard of anyone else having this issue. I am extremely anemic.  Before leaving Florida I was being worked up to find a reason for this. As this has gone on for years it is nothing for me to hover a H&H around 8-9/28  iron levels low , rdw low etc, in any case when I do go into a SCLS crisis event my h&h will go to a whopping 14/37 which may look normal but is "really high" for me clinically for me. When in reality it isn't high by any standards.


thanks for the feedback shannon

I don't recall anyone from Houston having co-authored any published articles on SCLS -- which would be ideal.  However, you can write to Dr. Druey at NIH and ask him if he knows any better and can recommend anyone there.

My generic advice is that you look for a compassionate physician, preferably a senior specialist in internal medicine, immunology, or hematology affiliated with a major university hospital, willing to do his/her homework on this rare disorder (namely, read the literature and follow the advice), and willing to consult with the few SCLS experts available on the topic -- like Dr. Druey.

There are several great hospitals in Houston. For example, the University of Texas Health Science Center is such an academic center, and if you go to their website and look up who's who among the faculty in their Department of Internal Medicine,, you can check out the physicians listed and see who might be a good fit because of what they specialize in (e.g., immune or vascular diseases).

Relevant examples I would consider are,,, or

At my first encounter, I would hand them a printout of key articles on SCLS found here under Disorder Resources, such as:, and  If you can't access them, let me know via email and I'll email them to you.

Ariel, if IVIG happens to have the power to abort, shorten, or otherwise minimize an episode of SCLS, well, one would probably want to speed up the infusion process as much as possible.  This is not medical advice, which only your physician can give you, but a logical hypothesis.

My understanding is that the patients in our community all infuse at different speeds allowed by the manufacturer and approved by their physicians.  For example, the manufacturer of Privigen recommends starting out at a speed of 0.5 mg/kg/min (0.005 mL/kg/min) and then increasing the speed up to a maximum of 8 mg/kg/min (0.08 mL/kg/min), see

In my case, I took the initiative years ago to gradually increase the speed of my infusions, with  my doctor's approval, because I needed to get back to work.  As a result, and for many years now, I have reached the maximum recommended speed, such that I infuse 90 g in less than 3 hours -- the actual time depends on how many bottles are involved (the more, the slower the process) and how available and prompt the nurses are (the slower they are in coming to change the bottles before air bubbles get into the line, the slower the whole process, of course).

Every time I would increase the infusion speed, I would get headaches in the days after, but they subsided with Tylenol, and within 3-4 months my body got used to the faster infusion speeds and I would have no more headaches.  Therefore, I would speed up the process again, which I did until I eventually reached the maximum speed allowed by the manufacturer.

If you are interested in speeding up your regularly scheduled infusion speed, and are willing to go through an adjustment process involving headaches or other unpleasant side effects, please consult your physician and have him/her prescribe the faster infusion target.  That way, should you ever have an episode of SCLS, you will be able to get the IVIG much faster than you do now, and benefit from that.

However, Claude probably holds the world's fastest IVIG infusion record, so you don't have to aim to beat him.  Cutting your infusion process in half the time -- from 6 to 3 hours -- may be a good enough and achievable objective!

Salut Arielbatt,

Les recommandations des entreprises offrant les médicaments doivent toujours être suivies à la lettre. Parfois, avec un peu d’expérience et en cas d’urgence, on peut adapter les recommandations avec souplesse et bon sens. J’utilise des immunoglobulines depuis 2005, sans avoir eu de problèmes particuliers avec les perfusions. Dans mon cas, je donne ma perfusion mensuelle de 140 g de Privigen (emballé +glucose 5% et 4000 ml) en 2 heures car au-delà de ce temps, une phlébite de la veine perforée commence. J’ai la chance d’être un sportif régulier avec un excellent système cardiovasculaire (sauf pour SCLS). Je pratique tous les jours le vélo ou le ski-alpinisme à un bon niveau. Lors de la réanimation, le temps presse et un taux de perfusion plus rapide que recommandé diminue le risque de choc hypovolémique mortel... le risque de réaction est donc relatif aux avantages. Le 10.02.2020, j’ai commencé la perfusion assez lentement. Après 15 minutes, le débit de perfusion a été augmenté au débit maximal de la ligne veineuse (cathéter court 18 G, débit 105 ml / min) sans aucun problème.

Sinceres salutations. Claude

Hello everyone, thanks Claude for sharing so quickly.
I have doubts about the rate at which it was infused. He says it was 80Gr in 2 hours. Are those emergency speeds? Or your body always resists that speed without problems. I apply that amount in 6 hours. Is the increase in speed something critical in the emergency that I should alert the doctors?

On your last issue, about having to switch from Gammagard to some other brand of IVIG after the turn of the year, you've got nothing to fear.  There can always be a bad batch once in a million, because after all IVIG is a plasma product and not an artificial, lab-manufactured compound, but the product is generally obtained in a similar manner following stringent quality controls -- no matter the brand.  Over the past dozen years, I have been given Privigen, Octagam, Gammagard and Gamunex-C, and I've had no adjustment problems at all.

The reason why different health systems, hospitals, and clinics use different brands is because they shop around and make their own deals with different manufacturers.  And I think the most common reason why they sometimes "run out" of a particular brand is probably because they are wanting to impress upon their current provider that they are willing to switch brands if they can get better pricing.

I started IVIG about 2 years ago at full dosage of 2g/kg over 2 days at a local infusion center, and had migraines and felt 'hungover' for about a week after.  I did realize about 2 weeks in, though, that my constant leak of 10 years was completely gone, so I contacted my Mayo doctor and asked about stopping, but he preferred to be proactive instead of reactive, and we compromised by stretching that to 8 weeks.  After 2 or 3 more treatments with a week to 10 days of recovery each, we adjusted to 1g/kg every 4 weeks. I've been on that schedule for almost a year now and am still not leaking and have not had any kind of episode since beginning. I do so appreciate the willingness of my doctors to listen and respect my opinion -

For prep, the week of my Friday treatment I increase fluid intake, (attempt to) eat cleanly, avoid alcohol, and get extra rest. I'm lucky to have my treatments at home, my nurse shows up about 9 and is gone by 1. I am a network engineer working from home, and able to work thru my treatment. In the beginning, I was missing at least 1 day/week after treatment with headaches & 'hangover', but the last few months I have been very close to not even noticing I've had a treatment. My husband has concerns about this being something we have to do/schedule/figure out for a lifetime, but I have come to look at it as luxury to slow down and take care of myself, listen to my body, eat and rest as I feel the need - and I am a strong believer that IVIG is worth it until something better comes along.

I am very lucky to have good veins, but I do have concerns about them becoming difficult with so much use.  I'm not interested in a port right now. I have been talking a bit with my nurse about the subcutaneous IG, maybe at a later time.

As far as travel, we will plan around my treatment. I, like Hans, am petrified of having an episode in another country, but we will bring Mayo info and contact wherever/whenever we go.

As a sort of side note, I have been getting Gammagard, but my insurance will not pay for it after January 1, and I have heard that the different brands can have very different reactions, so am a bit afraid that I may have to start figuring out how to cope post-treatment all over. I am going to look here on Rareshare for other patients' reactions to them. This site has been a blessing, you will find so much help here - good luck to you :-)

Hi Kevin,

I was in effect self diagnosed and was in your position several years ago. The key to confirming your diagnosis is the blood test result when you were ill. If you see Heamoglobin concentration during your illness then this conforms the condition. I think its the same for albumin levels. This shows fluid is leaking out of your capillary blood vessels so the blood volume decreases hence the concentration of the above goes up. It will return to normal when you get better. All the information you need is on the information part of this site but you may have to push your doctors to look into this as I did. Referral to Dr Drury at the NIH is then your next step - he is the world expert on this condition. Cheers, Another Kevin

Good afternoon... I've just gotten home from a hospital discharge brought on by what seems to be very similar symptoms 48 hours after my Covid booster (Pfizer).  Doctors have yet to come up with any kind of diagnosis for multiple hospital visits in the same cirumstances (2nd covid shot, flu vaccine in 2020).  I was finally fed up with not knowing, and after many many google searched, I ended up here. So far everyone's experience is the most similar to any other possible condition I've seen.  Not sure I can add anything of value to this thread at the moment, but wanted to post my first message after joining the community.

I think I echo a few voices in this group when I say that you're not alone. The fear, anxiety, ptsd, and/or panic attacks. It's hard to be comfortable with SCLS during flu season, significantly more through a pandemic. It's hard to have complete confidence in medicine. Especially when Dr. Druey says "...nothing is full proof...". But I have to echo the late George Micheal as well, "you gotta have faith" in IVIG (and a higher power if your into that). There's a reason I'm on the highest IVIG dose possible. Because I can, I know like a miracle it can and has saved those with SCLS, and as long as I can I will receive IVIG until the doc comes up with another preventive treatment or cure. I understand your hesitation with getting the booster. It's a lot to dissect. My second SCLS attack was because of the flu. I got diagnosed then. I even got my flu vaccine beforehand. My point goes back to Dr. Druey's words. Is it possible that you could have another attack ever again once you're on IVIG? Sure. But it's probably not going to happen and if it does IVIG will probably save your life without the need for life support. Full disclosure, I've received both moderna vaccines and booster with no SCLS attacks and I'm receiving 2g/kg IVIG every 4 weeks.

Getting diagnosed with SCLS stinks, but it beats not having a diagnosis at all and having no IVIG support. Don't hesitate to reach out if you need to talk.

The Consequences of the Covid-19 Pandemic on SCLS Patients

The Consequences of the Covid-19 Pandemic on SCLS Patients

Abstract: The authors report on the fate of 30 known SCLS patients from Europe through mid-July 2021: 90% (27) of them were receiving IVIG on a regular basis, and two-thirds (20) of them were vaccinated. Five of the ten who were unvaccinated patients experienced an episode of SCLS and 4 of them died as a result, even though none had evidence of Covid-19 pneumonia. Covid vaccination was uneventful in 18 out of the 20 patients, including 2 who were not receiving IVIG. Two patients treated with IVIG had a relapse after a second dose of mRNA vaccine, with a favorable outcome in both cases. In addition, five patients were newly diagnosed with SCLS, none of whom were receiving IVIG: 4 of them were unvaccinated and had an episode of SCLS after contracting Covid, and the 5th one after receiving a first Covid vaccination. One of the unvaccinated four died, while the rest survived. In sum, the Covid pandemic has had serious consequences in patients with SCLS. Covid infections are associated with a high risk of SCLS episodes, and all Covid vaccines can trigger episodes. High-dose IVIG remains the only effective preventive treatment and should not be stopped during the pandemic. The risk/benefit ratio favors Covid vaccination in SCLS patients receiving IVIG.

Chronic SCLS treatment with IVIG: Case & literature

Chronic systemic capillary leak syndrome treatment with intravenous immune globulin: Case report and review of the literature 

Abstract: A rarely described chronic form of SCLS (cSCLS) presents as refractory edema, with pleural and/or pericardial effusions and hypoalbuminemia. These entities are differentiated by massive and periodic episodes of capillary leak, which can result in shock in SCLS, and chronic refractory edema in cSCLS. The etiologies of these disorders are poorly understood, but both acute and chronic forms often present with an associated monoclonal gammopathy. Flares of the SCLS have been reduced by treatment with intravenous immune globulin (IVIG). Only six cases of cSCLS have been reported, and previous treatments have included steroids, terbutaline, and theophylline. Based upon the reported responses of SCLS to IVIG, we present the case of a 54-year-old man with cSCLS where ongoing treatment with IVIG resulted in a marked and sustained improvement in the signs and symptoms of the capillary leak syndrome.

Handling Shock in SCLS: Less Is More

Handling shock in idiopathic systemic capillary leak syndrome (Clarkson’s disease): less is more 

Abstract: SCLS presents with recurrent potentially life-threatening episodes of hypovolemic shock associated with severe hemoconcentration and hypoproteinemia. Here the authors summarize 40 years’ experience in treating shock in Italian SCLS patients to derive a therapeutic algorithm. Records from 12 patients were informative for treatment modalities and outcome of 66 episodes of shock. Episodes are divided in 3 phases and treatment recommendations are the following: (1) prodromal symptoms-signs (growing malaise, oligo-anuria, orthostatic
dizziness) last 6-12 hours and patients should maintain rigorous bed rest. (2) The acute shock phase lasts 24-36 hours; patients should be admitted to ICU, placed on restrictive infusion of fluids favoring cautious boluses of high-molecular-weight plasma expanders when SAP < 70 mmHg; and monitored for cerebral/cardiac perfusion, myocardial edema and signs of compartment syndrome. (3) The post-acute (recovery) phase may last from 48 hours to 1 week; monitor for cardiac overload to prevent cardiac failure; in case of persistent renal failure, hemodialysis may be necessary; consider albumin infusion. Complications listed by frequency in our patients were acute renal failure, compartment syndrome and neuropathy, rhabdomyolysis, myocardial edema, pericardial-pleural-abdominal effusion, cerebral involvement, acute pulmonary edema and deep vein thrombosis.

A natural mouse model reveals genetic determinants of SCLS

A natural mouse model reveals genetic determinants of systemic capillary leak syndrome

Abstract: SCLS is a disorder of unknown etiology characterized by recurrent episodes of vascular leakage of proteins and fluids into peripheral tissues, resulting in whole-body edema and hypotensive shock. The pathologic mechanisms and genetic basis for SCLS remain elusive. Previous histological studies of skin and muscle of SCLS patients have failed to uncover gross abnormalities within the microvasculature that could account for this phenotype. Here the authors identified an inbred mouse strain, SJL, which recapitulates cardinal features of SCLS, including susceptibility to histamine- and infection-triggered vascular leak. They named this trait “Histamine hypersensitivity” (Hhs/Hhs) and mapped it to Chromosome 6. Hhs is syntenic to the genomic locus most strongly associated with SCLS in humans (3p25.3), revealing that the predisposition to develop vascular hyperpermeability has a strong genetic component conserved between humans and mice and providing a naturally occurring animal model for SCLS. Genetic analysis of Hhs may reveal orthologous candidate genes that contribute not only to SCLS, but also to normal and dysregulated mechanisms underlying vascular barrier function more generally. Future studies including assessment of expression and sequence of top Hhs candidate genes in SCLS patients and mice and their role in endothelial responses to inflammation will be essential to determine their contribution.

Intravenous Immunoglobulins Improve Survival in Monoclonal Gammopathy-Associated SCLS

Intravenous Immunoglobulins Improve Survival in Monoclonal Gammopathy-Associated SCLS

Abstract: We conducted a cohort analysis of all patients included in the European Clarkson disease registry between January 1997 and March 2016. From diagnosis to last follow-up, studied outcomes (e.g., the frequency and severity of attacks, death, and evolution toward multiple myeloma) and the type of preventive treatments administered were monitored every 6 months. Sixty-nine patients (M/F sex ratio 1:1; mean ± SD age at disease onset 52 ± 12 years) were included in the study. All patients had monoclonal gammopathy of immunoglobulin G type, with kappa light chains in 47 (68%).Twenty-four patients (35%) died after 3.3 (0.9-8) years. Fifty-seven (86%) patients received at least one preventive treatment, including intravenous immunoglobulins (IVIg) n = 48 (73.8%), theophylline n = 22 (33.8%), terbutaline n = 22 (33.8%), and thalidomide n = 5 (7.7%). In the 65 patients with follow-up, 5- and 10-year survival rates were 78% (n = 35) and 69% (n = 17), respectively. Preventive treatment with IVIg and terbutaline were the only factors significantly associated with survival in multivariate analysis. Neither the use of thalidomide nor theophylline was associated with improved survival. Five- and 10-year survival rates in patients treated with IVIg were 91% and 77%, respectively, compared to 47% and 37% in patients not treated with IVIg. Patients treated with IVIg were more likely to be free of recurrence, severe recurrence, and alive at the end of follow-up. Furthermore, all but one patient who did not experience a severe relapse were treated with IVIg. Since preventive treatment with IVIg was the strongest factor associated with survival, the use of IVIg is suggested as the first line in prevention therapy.

Whole Exome Sequencing of SCLS Patients

Whole Exome Sequencing of Adult and Pediatric Cohorts of the Rare Vascular Disorder Systemic Capillary Leak Syndrome

Abstract: The extent to which genetic abnormalities contribute to SCLS is unknown. The authors identified pediatric and adult cohorts with characteristic clinical courses and sought to identify a possible genetic contribution to SCLS through the application of Whole Exome Sequencing (WES). On the basis of 9 adult and 8 pediatric SCLS patients and available unaffected first-degree relatives, they did not identify a uniform germline exomic genetic etiology for SCLS. However, WES did identify several candidate genes for future research.

Idiopathic SCLS (Clarkson syndrome) in childhood

Idiopathic systemic capillary leak syndrome (Clarkson syndrome) in childhood: systematic literature review

Abstract: The authors performed a systematic review of the literature on Clarkson syndrome in subjects less than 18 years of age, and identified 24 reports, published since 1989, providing data on 32 otherwise healthy subjects, who experienced 67 well-documented episodes of SCLS. The condition affected more frequently girls (21, 66%) than boys, presented throughout childhood, and was preceded by a mostly viral illness in 75% of cases. The presence of a monoclonal gammopathy (MGUS) was never reported. Uncompensated circulatory shock, muscle compartment syndrome, acute kidney injury, pulmonary edema, and either pleural or pericardial effusion were, in decreasing order of frequency, the most common complications. Four patients died. In sum, SCLS develops not only in adulthood but also in childhood, but of potential significance is that in this age group the condition is not linked to an MGUS, and thus it could be that it does not play a pivotal pathogenic role.

Clinical Presentation, Management, and Prognostic Factors of SCLS

Clinical Presentation, Management, and Prognostic Factors of Idiopathic Systemic Capillary Leak Syndrome: A Systematic Review

Abstract: A total of 133 case reports (161 patients) and 5 case series (102 patients) of idiopathic SCLS were included in a survey of articles published through end-2016. The findings include that patients had hypotension (81.4%), edema (64.6%), and previous flu-like illness (34.2%). They were often misdiagnosed as having hypovolemic shock, septic shock, polycythemia vera, or angioedema. Thirty-seven patients died (23%) mainly because of complications from SCLS (78.4%). There were significant differences in the survival rates between patients who were treated with prophylactic b2 agonists, methylxanthines, and intravenous immunoglobulins and those who were not. The estimated 1-, 5-, and 10-year survival rate of patients treated with intravenous immunoglobulins was 100%, 94%, and 94%, respectively. The results of this review suggest that prophylactic use of intravenous immunoglobulins is the most effective treatment in reducing the mortality rate of SCLS patients.

The Clinical Picture of Severe SCLS Episodes Requiring ICU Admission

The Clinical Picture of Severe SCLS Episodes Requiring ICU Admission

Abstract: SCLS is a very rare cause of recurrent hypovolemic shock. Few data are available on its clinical manifestations, laboratory findings, and outcomes of those patients requiring ICU admission.  This study was undertaken to describe the clinical pictures and ICU management of severe SCLS episodes.  This multicenter retrospective analysis concerned patients entered in the European Clarkson's disease (EurêClark) Registry and admitted to ICUs between May 1992 and February 2016.  Fifty-nine attacks occurring in 37 patients (male-to-female sex ratio, 1.05; mean ± SD age, 51 ± 11.4 yr) were included.  Among 34 patients (91.9%) with monoclonal immunoglobulin G gammopathy, 20 (58.8%) had kappa light chains.  ICU-admission hemoglobin and proteinemia were respectively median (interquartile range) 20.2 g/dL (17.9-22 g/dL) and 50 g/L (36.5-58.5 g/L).  IVIG was infused during 15 episodes (25.4%).  A compartment syndrome developed during 12 episodes (20.3%).  Eleven (18.6%) in-ICU deaths occurred. Bivariable analyses (the 37 patients' last episodes) retained Sequential Organ-Failure Assessment score greater than 10 (odds ratio, 12.9 [95% CI, 1.2-140]; p = 0.04) and cumulated fluid-therapy volume greater than 10.7 L (odds ratio, 16.8 [1.6-180]; p = 0.02) as independent predictors of hospital mortality.  In conclusion, high-volume fluid therapy was independently associated with poorer outcomes.  IVIG use was not associated with improved survival; hence, its use in an ICU setting should be considered prudently and needs further evaluation in future studies.

Capillary leak syndrome: etiologies, pathophysiology, and management

Capillary leak syndrome: etiologies, pathophysiology, and management

Abstract: In various human diseases, an increase in capillary permeability to proteins leads to the loss of protein-rich fluid from the intravascular to the interstitial space. Although sepsis is the disease most commonly associated with this phenomenon, many other diseases can lead to a “sepsis-like” syndrome with manifestations of  diffuse pitting edema, exudative serous cavity effusions, noncardiogenic pulmonary edema, hypotension, and, in some cases, hypovolemic shock with multiple-organ failure. The term capillary leak syndrome has been used to describe this constellation of disease manifestations associated with an increased capillary permeability to proteins. Diseases other than sepsis that can result in capillary leak syndrome include the idiopathic systemic capillary leak syndrome or Clarkson’s disease, engraftment syndrome, differentiation syndrome, the ovarian  hyperstimulation syndrome, hemophagocytic lymphohistiocytosis, viral hemorrhagic fevers, autoimmune diseases, snakebite envenomation, and ricin poisoning. Drugs including some interleukins, some monoclonal antibodies, and gemcitabine can also cause capillary leak syndrome. Acute kidney injury is commonly seen in all of these diseases. In addition to hypotension, cytokines are likely to be important in the pathophysiology of acute kidney injury in capillary leak syndrome. Fluid management is a critical part of the treatment of capillary leak syndrome;  hypovolemia and hypotension can cause organ injury, whereas capillary leakage of administered fluid can worsen organ edema leading to progressive organ injury. The purpose of this article is to discuss the diseases other than sepsis that produce capillary leak and review their collective pathophysiology and treatment.

Idiopathic systemic capillary leak syndrome (Clarkson disease)

Idiopathic systemic capillary leak syndrome (Clarkson disease)

Abstract: The enigmatic systemic capillary leak syndrome (SCLS) named for Dr Clarkson is characterized by transient and severe but reversible hemoconcentration and hypoalbuminemia caused by leakage of fluids and macromolecules into tissues. Although less than 500 cases of SCLS have been reported in the literature since 1960, the condition is probably underdiagnosed because of a lack of awareness and a high mortality without treatment. Treatment of acute SCLS remains primarily supportive. Prophylaxis with IVIG appears promising, but this therapy is nonspecific and expensive. Mechanistic understanding of SCLS is in its infancy. As a result, clinicians today cannot predict when or how badly SCLS will flare; targeted therapies do not yet exist, and prolonged remission or cure remains elusive. Our working hypothesis invokes exaggerated microvascular endothelial responses to surges of otherwise routinely encountered inflammatory mediators. This emerging disease model lends itself to innovative patient-centered translational research in the ways highlighted above. It is our hope that detailed and personalized investigation of intraendothelial responses among individual patients with SCLS might illuminate novel genetic and molecular control mechanisms. In turn, such advances could deliver the diagnostic, prognostic, and therapeutic tools sorely needed to combat this devastating disease.

The Mayo Clinic Experience with SCLS

Idiopathic Systemic Capillary Leak Syndrome (Clarkson's Disease): The Mayo Clinic Experience

Abstract: Of the 34 patients whose records were reviewed, 25 fulfilled all diagnostic criteria for SCLS. The median age at diagnosis of SCLS was 44 years. Median follow-up of surviving patients was 4.9 years, and median time to diagnosis from symptom onset was 1.1 years (interquartile range, 0.5-4.1 years). Flulike illness or myalgia was reported by 14 patients (56%) at onset of an acute attack of SCLS, and rhabdomyolysis developed in 9 patients (36%). Patients with a greater decrease in albumin level had a higher likelihood of developing rhabdomyolysis (P=.03). Monoclonal gammopathy, predominantly of the IgG-kappa type, was found in 19 patients (76%). The progression rate to multiple myeloma was 0.7% per person-year of follow-up. The overall response rate to the different therapies was 76%, and 24% of patients sustained durable (>2 years) complete remission. The estimated 5-year overall survival rate was 76% (95% confidence interval, 59%-97%). In conclusion, SCLS, a rare disease that occurs in those of middle age, is usually diagnosed after a considerable delay from onset of symptoms. The degree of albumin decrement during an attack correlates with development of rhabdomyolysis. A reduction in the frequency and/or the severity of attacks was seen in nearly three-fourths of patients who were offered empiric therapies. The rate of progression to multiple myeloma appears to be comparable to that of monoclonal gammopathy of undetermined significance.

Genome-Wide SNP Analysis of SCLS

Genome-Wide SNP Analysis of SCLS.

Abstract: Polymorphisms in genes whose functional annotations suggest involvement in cell junctions and signaling, cell adhesion, and cytoskeletal organization, correlate with our previous mechanistic studies of SCLS sera. Such annotations provide a framework for future allelic discrimination strategies to validate top-ranked SNPs discovered here, as well as novel SNPs unique to the SCLS cohort detected by exome capture sequencing. Although the findings must be corroborated in a larger cohort, they provide a springboard for discovery of underlying pathophysiological mechanisms, biomarkers, and avenues for therapy.

IVIG in SCLS: A Case Report and Review of Literature

IVIG in SCLS: Report and Review of Literature.

Abstract: In recent years, IVIG has become a common first-line prophylactic therapy in most patients with benefits at the dose of 2 gr/kg once a month. Here the authors report the case of a 49-year-old male patient in Italy -- he is a member of this community -- with SCLS treated successfully with a lower dose of IVIG (1 gr/kg monthly) in the maintenance phase. He presented no acute episodes in a follow-up period of 28 months. The authors describe prophylactic treatments for SCLS in the literature and compare their patient to another 18 who received IVIG in follow-up.

Mechanistic Classification of SCLS

Mechanistic Classification of SCLS.

Abstract: The authors analyzed circulating mediators of vascular permeability and proinflammatory cytokines in acute episodic sera from 14 patients with SCLS, and sera from 37 healthy control subjects. They monitored barrier function of human microvascular endothelial cells (HMVEC) after treatment with SCLS sera using transendothelial electrical resistance assays. Consistent with their previous study, the permeability factor vascular endothelial growth factor (VEGF) was increased in sera from acutely ill subjects with SCLS. An analysis of samples from one SCLS patient who has not responded to any preventive therapies (and who is a member of this Community), suggests that SCLS may have clinically varying forms, and that within the group of patients with SCLS, different cytokines may mediate the capillary leak. Therefore, quantitative molecular and humanized cell-based assays for humoral mediators of permeability should improve diagnostic specificity for SCLS and enable clinicians to screen for effective therapies.

High-Dose IVIG Therapy for SCLS

High-Dose IVIG Therapy for SCLS.

Abstract: We evaluated IVIG prophylactic therapy in a cohort of 29 patients with Systemic Capillary Leak Syndrome in a longitudinal follow up study. All patients received treatments at the discretion of their primary providers and retrospectively via questionnaire recorded symptoms beginning with their first documented episode of the SCLS until May 31, 2014. Twenty-two out of 29 patients responded to the questionnaire, and 18 out of the 22 respondents received monthly prophylaxis with IVIG during the study period for a median interval of 32 months. The median annual attack frequency was 2.6/patient prior to IVIG therapy and 0/patient following initiation of IVIG prophylaxis (P = 0.001). 15 out of 18 subjects with a history of one or more acute SCLS episodes experienced no further symptoms while on IVIG therapy. In conclusion, IVIG prophylaxis is associated with a dramatic reduction in the occurrence of SCLS attacks in most patients, with minimal side effects.

SCLS in Children

Idiopathic Systemic Capillary Leak Syndrome in Children

Abstract: Adult subjects with systemic capillary leak syndrome (SCLS) present with acute and recurrent episodes of vascular leak manifesting as severe hypotension, hypoalbuminemia, hemoconcentration, and generalized edema. We studied clinical disease characteristics, serum cytokine profiles, and treatment modalities in a cohort of children with documented SCLS. Six children with SCLS were recruited from the United States, Australia, Canada, and Italy. Serum cytokines from SCLS subjects and a group of 10 healthy children were analyzed. Children with SCLS (aged 5-11 years old) presented with at least 1 acute, severe episode of hypotension, hypoalbuminemia, and hemoconcentration in the absence of underlying causes for these abnormalities. In contrast to what is observed in adult SCLS, identifiable infectious triggers precipitated most episodes in these children, and none of them had a monoclonal gammopathy. We found elevated levels of chemokine (C-C motif) ligand 2 (CCL2), interleukin-8, and tumor necrosis factor α in baseline SCLS sera compared with the control group. All patients are alive and well on prophylactic therapy, with 4 patients receiving intravenous or subcutaneous immunoglobulins at regular intervals. The clinical manifestations of pediatric and adult SCLS are similar, with the notable exceptions of frequent association with infections and the lack of monoclonal gammopathy. Prophylactic medication, including high dose immunoglobulins or theophylline plus verapamil, appears to be safe and efficacious therapy for SCLS in children.

Systemic capillary leak syndrome: recognition prevents morbidity and mortality

Systemic capillary leak syndrome: recognition prevents morbidity and mortality.

Abstract: The authors report on a case of SCLS in Australia involving a 61-year-old male who was properly diagnosed after his third episode, to increase awareness of the condition and to highlight the benefits of prophylactic intravenous immunoglobulin (IVIG) in this condition. The diagnosis was made by exclusion and clinically by a classic triad of hypotension, hypoalbuminaemia and haemoconcentration. There have been recent advances in understanding the pathophysiological basis for SCLS and in effective prophylaxis, and the authors and patient benefitted from said advances.

Laboratory Evidence of SCLS and of the Effectiveness of IVIG

Vascular Endothelial Hyperpermeability Induces The Clinical Symptoms of Clarkson Disease (The Systemic Capillary Leak Syndrome)

Abstract: The authors report clinical and molecular findings on 23 subjects, the largest SCLS case series to date. Application of episodic SCLS sera, but neither the purified immunoglobulin fraction nor sera obtained from subjects during remission, to human microvascular endothelial cells caused vascular endothelial cadherin (VE-cadherin) internalization, disruption of inter-endothelial junctions, actin stress fiber formation, and increased permeability in complementary functional assays without inducing endothelial apoptosis. Intravenous immunoglobulin (IVIG), one promising therapy for SCLS, mitigated the permeability effects of episodic sera directly. Consistent with the presence of endogenous, non-immunoglobulin, circulating permeability factor(s) constrained to SCLS episodes, we found that two such proteins, vascular endothelial growth factor (VEGF) and angiopoietin 2 (Ang2), were elevated in episodic SCLS sera but not in remission sera. Antibody-based inhibition of Ang2 counteracted permeability induced by episodic SCLS sera. Comparable experiments with anti-VEGF antibody (bevacizumab) yielded less interpretable results, likely due to endothelial toxicity of VEGF withdrawal. Our results support a model of SCLS pathogenesis in which non-immunoglobulin humoral factors such as VEGF and Ang2 contribute to transient endothelial contraction, suggesting a molecular mechanism for this highly lethal disorder.

Successful Treatment of SCLS with IVIG

Successful Treatment of Systemic Capillary Leak Syndrome with Intravenous Immunoglobulins.

Abstract: The authors report on a 48-year-old woman in Spain who had her 1st episode of SCLS in 1997 and was initially put on a regimen of terbutaline and aminophylline, but went on to endure 20 additional episodes in the subsequent 3 years. She was then treated with melphalan-prednisone for a year and the frequency and intensity of her episodes diminished and even disappeared. In 2005, however, the episodes returned and in 2008 she was finally put on a regimen of IVIG (2 g/kg) every 6 weeks. She has had no more episodes since then.

Comment on SCLS

Comment on The Systemic Capillary Leak Syndrome.

Abstract: The authors report on 2 additional patients from the United States with SCLS in whom prophylaxis with terbutaline and theophylline failed, but who had no further episodes after the initiation of IVIG therapy. There are additional published reports of successful prophylaxis with IVIG cited, and the authors are also aware of yet another case. Given the present state of knowledge and despite the high cost, the authors strongly believe that IVIG is the optimal prophylaxis and should be the initial choice to prevent attacks in patients with SCLS.

IVIG: A Promising Approach to SCLS

High-dose intravenous immunoglobulins: A promising therapeutic approach for idiopathic systemic capillary leak syndrome.

Abstract: The article reports the case of a 40-year-old woman with chronic SCLS treated in Berne, Switzerland, with high-dose intravenous immunoglobulins (IVIG) after a prophylactic therapy with theophylline and terbutaline (T&T) was poorly tolerated and failed to decrease the frequency and severity of the attacks. During the 5 years she was on T&T the patient suffered from about 20 similar episodes of mild to moderate shock, often requiring hospital re-admission and supportive therapy. So far, 10 months of prophylactic therapy with IVIG (2gr/kg/month) have resulted in an impressive reduction of intensity and frequency of attacks, confirming the finding of other case studies.

Lessons from 28 European Patients with SCLS

The Systemic Capillary Leak Syndrome: A Case Series of 28 Patients From a European Registry.

Abstract: The article describes the clinical characteristics, laboratory findings, treatments, and outcomes of patients with SCLS who were not previously reported in the literature. These European patients with SCLS were treated and monitored from the start of 1997 until end-July 2010. Survival rates were 89% at 1 year and 73% at 5 years; instances of death were directly related to SCLS attacks in 6 cases (75% of total). Treatments of various kinds increased the chances of survival: Five years after diagnosis, survival rates were 85% in 23 patients who had received a treatment and just 20% in 5 patients who had not. The authors provide additional evidence that a prophylactic treatment with IVIG tends to reduce the frequency and severity of attacks, and may improve the survival of patients with SCLS.

Mayo Clinic write-up on SCLS

The Mayo Clinic's summary of the diagnosis and treatment of SCLS.

During an episode of systemic capillary leak syndrome, fluids are administered intravenously to maintain the patient's blood pressure and to prevent damage to vital organs such as the kidneys, heart and brain. The amount of fluid must be carefully controlled. An attempt to normalize blood pressure through aggressive fluid administration can cause destructive swelling of the body's extremities and overload the kidneys and lungs when the body needs to eliminate the excess fluids after the episode passes.

Glucocorticoids (steroids) are often injected during an acute capillary leak syndrome attack to reduce or stop the capillary leak. This is sometimes successful. Fluid pressure in muscles may be monitored. Emergency surgery may be needed to relieve pressure and minimize damage to muscles and nerves in the arms and legs.

Once the capillary walls stop leaking and fluids start to be reabsorbed, patients are usually given diuretics to speed up elimination of the fluids before they accumulate in the lungs and other vital organs, which can be a fatal complication.

Patients who avoid organ and limb damage in a capillary leak syndrome episode tend to recover their health after several days, once the capillary walls return to normal and the accumulated fluid is expelled from the body through urination.

Although no cure has been found for systemic capillary leak syndrome, the frequency and/or severity of episodes is often reduced by having patients take certain asthma medications: theophylline and terbutaline. Patients also may benefit from intravenous treatment with immunoglobulin or by taking thalidomide.

Patients may also be prescribed corticosteroid pills such as prednisone to be taken at the first sign of symptoms of another capillary leak.

IVIG as Treatment for SCLS

Immunoglobulins for Treatment of Systemic Capillary Leak Syndrome

Abstract: A 43-year-old white woman in France diagnosed with SCLS was put on the recommended combination of Theophylline plus Terbutaline, but she nevertheless had 10 episodes of severe capillary leak during 2001-mid-2007, necessitating intensive care unit admission for her last 3 episodes. She was then put on IVIG administered every 6 weeks, and this yielded a dramatic improvement such that she has had no more episodes and has returned to her normal lifestyle.

IVIG as Treatment for SCLS

High-Dose Intravenous Immunoglobulins Dramatically Reverse Systemic Capillary Leak Syndrome.

Abstract: The objective of this study was to report the dramatic improvement of patients with systemic capillary leak syndrome obtained with high-dose intravenous immunoglobulins. Systemic capillary leak syndrome is a rare and life-threatening disorder characterized by hypotension that can lead to shock, weight gain, hypoalbuminemia, and elevated hematocrit secondary to unexplained episodic capillary fluid extravasation into the interstitial space. Because its cause is unknown, systemic capillary leak syndrome treatment has remained largely supportive. Intravenous immunoglobulins administration to a patient with refractory systemic capillary leak syndrome yielded dramatic improvement. The patient is still alive 11 yrs after systemic capillary leak syndrome diagnosis and receives intravenous immunoglobulins monthly. Later, based on that result, intravenous immunoglobulins were successfully given to two other patients during the acute phase of systemic capillary leak syndrome. Both are still alive 8 and 1.5 yrs after receiving intravenous immunoglobulins at the onset of each flare. In conclusion, intravenous immunoglobulins were effective against systemic capillary leak syndrome symptoms in three patients, but their exact mechanism remains unknown. Their immunomodulatory effect merits further investigation.

The Systemic Capillary Leak Syndrome

Narrative review: the systemic capillary leak syndrome

Abstract: The systemic capillary leak syndrome (SCLS) is a rare disease of reversible plasma extravasation and vascular collapse accompanied by hemoconcentration and hypoalbuminemia. Its cause is unknown, although it is believed to be a manifestation of transient endothelial dysfunction due to endothelial contraction, apoptosis, injury, or a combination of these. Fewer than 150 cases of SCLS have been reported, but the condition is probably underrecognized because of its nonspecific symptoms and signs and high mortality rate. Patients experience shock and massive edema, often after a nonspecific prodrome of weakness, fatigue, and myalgias, and are at risk for ischemia-induced organ failure, rhabdomyolysis and muscle compartment syndromes, and venous thromboembolism. Shock and edema reverse almost as quickly as they begin, at which time patients are at risk for death from flash pulmonary edema during rapid fluid remobilization. Diagnosis is made clinically and by exclusion of other diseases that cause similar symptoms and signs, most notably sepsis, anaphylaxis, and angioedema. Acute episodes are treated with vasopressor therapy and judicious fluid replacement, possibly with colloid solutions for their osmotic effects, to prevent the sequelae of underperfusion. Prognosis is uncertain, but patients who survive an initial severe SCLS episode are estimated to have a 10-year survival rate greater than 70%. Much remains to be learned about SCLS, and clinicians should consider the diagnosis in patients with unexplained edema, increased hematocrit, and hypotension.


Clinical Trials

Cords registry

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access.

Enrolling is easy.

  1. Complete the screening form.
  2. Review the informed consent.
  3. Answer the permission and data sharing questions.

After these steps, the enrollment process is complete. All other questions are voluntary. However, these questions are important to patients and their families to create awareness as well as to researchers to study rare diseases. This is why we ask our participants to update their information annually or anytime changes to their information occur.

Researchers can contact CoRDS to determine if the registry contains participants with the rare disease they are researching. If the researcher determines there is a sufficient number of participants or data on the rare disease of interest within the registry, the researcher can apply for access. Upon approval from the CoRDS Scientific Advisory Board, CoRDS staff will reach out to participants on behalf of the researcher. It is then up to the participant to determine if they would like to join the study.

I had my first episode of what turned out to be SCLS in November 2005, and was very lucky to have survived it (though with permanent disabilities in arms and legs, and thus in hands and feet) and to have been diagnosed correctly within days.

I went on to have 2 other life- and limb-threatening episodes in April 2007 and March 2009, requiring 2+ weeks of Intensive Care hospitalization to keep my organs alive and emergency fasciotomies to preserve the muscles and nerves I still have in my extremities.

I also had 7 episodes of lesser severity (Dec. 2007, June 2008, June 2009, July 2009, September 2009, and two in November 2009), because I realized I was having them early on, which allowed me to get a massive dose of steroids (Prednisone pills and/or injections of Solu-Medrol and Albumin) that effectively stopped the capillary leak phase of SCLS.

Given the increased frequency of my episodes of SCLS, despite having taken the recommended doses of the traditional medications (e.g., Theophylline, Terbutaline and Singulair), I was given my first infusion of IVIG in November 2009 and have had monthly infusions since then with no adverse side effects whatsoever. So far, so very good: for over a decade I had no more episodes of SCLS, though I did have one in February 2020, after coming down with Influenza A days before I was due for my next IVIG infusion, which I hope will prove to be the exception to the rule.

While I was among the first SCLS patients in the United States to benefit from an IVIG therapy, most other patients who had previously been getting this medication in Europe, and virtually all patients around the world who have since received IVIG, have stopped having episodes of SCLS.

Our stories are now told in a number of case studies published in various medical journals, and there is also a scientific article showing the efficacy of IVIG in countering SCLS in laboratory conditions based on our blood samples before and after receiving IVIG, as well as several articles with the results of surveys of SCLS patients who have been on IVIG.  The evidence that IVIG is the best and almost always successful therapy for the prevention of episodes of SCLS is now overwhelming.

Hello Arturo, thank you so much for all the information you have provided. My daughter was discharged 1/27/10 from the hospital, and started on theophylline, and terbutaline. Is Dr. Pecker familiar with SCLS?


Of course! Otherwise I wouldn't recommend him! He's the most knowledgeable person about SCLS in all of New York. And don't forget to ask for a tranquilizer for your daughter if you notice that, as the dosage is increased, she starts to get very nervous. It's a well-known side effect.

Hello, I am new to RareShare. My 16-year-old daughter is currently in the ICU diagnosed with SCLS. When do you start these traditional medications?


I'm so sorry to hear about your teenage daughter. SCLS in young people is very rare, so once she is discharged from the hospital, I suggest you get a 2nd opinion to make sure she was diagnosed correctly. I see that you live in the state of New York. If by chance you are within driving distance of Manhattan, I recommend you seek an appointment with Dr. Mark Pecker of Weill Cornell/New York Presbyterian Hospital, tel. 212-746-2210. Once confirmed, your MD will probably suggest that she start taking Theophylline and Singulair, perhaps with a tranquilizer to offset the side effects of the former. If she still has episodes despite taking those meds, the treatment of last resort is IVIG. In the meantime, you must educate her, yourself, and your personal doctor and the ICU staff at the hospital nearest your home about how to treat an episode of SCLS without causing any collateral damage. To start, have them go through this site (see Disorder Details and Disorder Resources).

How many people have received the loading dose of IVIG 1-2 gm/kg over 2 days without it being during an acute attack? I have only seen literature (one article) supporting it given during an acute attack. I have tried every drug out there to no avail. Since I live in Minnesota I have been to Mayo twice to see Dr. Greipp. Our last discussion we talked about IVIG and Revlimid but decided that IVIG might be the next drug to try. Thank you for your help.





Heptagona (Steve)



P.S. At a later date I will share my SCLS story with the group.


Dear Steve:



The only U.S. patient we've heard from who has just started to get IVIg on a monthly basis is Nolan, who lives in Idaho. Check out the Discussion Forum topic "IVIG" and you will read all about it.



It appears that monthly infusions of IVIg have become the treatment of choice in Europe and in Quebec, and as you will read, our (few) community members from those parts of the world are very pleased with the results.



A recent article published in France in French mentions that many European patients have been on IVIg in recent years, but unfortunately does not say what the success rate has been. If you'd like a copy, send me a private email to and I'll send it to you.



Here in the U.S. we have the practical problem that IVIg infusions are very expensive (about $10,000/month), and thus most insurance companies will not cover it unless there is published evidence that it works. However, you could explore the possibility by getting your own MDs and also Mayo's Dr. Greipp to write letters of support to your insurance company, appealing for coverage and explaining that nothing else has worked. After all, Nolan succeeded, so his precedent may be useful.

Bonjour Arturo.


j'ai une petite question.


Je me demandais combien il y a de personnes environs dans le monde qui ont été diagnostiqué avec le Syndrome de fuite capillaire systémique?



c'est que c'est la collect de sang dans ma municipalité et je veux faire écrire un article sur moi dans le journal local afin d'inciter les gens à donner du sang.


alors, je veux inscrire quelques statistiques dans l'article.







Bonjour Josée!



Nous ne savons pas combien de personnes souffrent de SCLS, mais comme vous pouvez le voir partir de ce site Web, nous sont découvrir plus en plus chaque semaine qui enfin obtenir le bon diagnostic. Pour l'instant, je dirais que nous savons de moins de 1 000 patients qui ont SCLS.

Arturo, please accept my thanks for pursuing the SCLS story. I have been running blind with very little knowledge of my condition since 2005, and was unaware of what I had until recently. Until today, I have had no contact with others who have SCLS. I am scheduling a first-time visit to Dr. Greipp in April. Have you visited Mayo?


I'm very glad you found your way to RareShare, and feel free to contact me directly at with whatever other personal questions you have. As a matter of fact, no, I've never been to the Mayo Clinic to see Dr. Greipp, but that is because my doctors took the initiative to speak to him on the phone and to read up on what he and others have published on SCLS. I am very grateful to Dr. Greipp that he has been willing to give his best advice -- at no charge -- to my doctors and to others around the world.

Arturo, does any one group or person keep track of SCLS patients? What is the count of SCLS patients?




No, there is no official national or international registry of SCLS patients as of yet, though I'm working on that. As the stories told in this virtual community demonstrate, many of us have only recently been properly diagnosed, and have only recently found a means to make our existence known to each other and the world. Chances are that many victims of SCLS die during their first episode -- before they are properly diagnosed. Even so, SCLS is likely to be a rare disease among rare diseases. It was first described in the medical literature in an article published in 1960.

I recently have been diagnosed with severe capillary leak syndrome. My first attack was 20 years ago. My fifth and most recent attack occured this past July. During the years, I was misdiagnosed and given little hope of ever finding out what was wrong with me. Since my diagnosis, I have met with Dr. Greipp and Dr. Druey at NIH. Dr. Druey sent me the link to the Washington Post article speaking about your advocacy for SCLS. I applaud your dogmatic persistence with NIH so that they allocated funding for this research project. I want to help raise awareness and funding for additional research. Are you still actively pursuing this? Please let me know how I can help.




Welcome to this SCLS community Robert! I am very glad that you were finally diagnosed properly. God only knows how many others there are out there who have yet to be diagnosed correctly -- hopefully before they die or suffer irreparable damage to organs and/or limbs. Write to me at so that I may follow up with you privately.

I thank Rick for his comment on the G-suits for the pilots. I myself found an anti-G suit of the Swiss Air Force. I used it twice, in 2 different cases of serious shocks (undetectable blood pressure) in my residence, to try to mobilize blood remaining in the venous compartment of the legs and the lower abdomen and to support its return towards the heart. This process is effective in the initial phase of the capillary leak, when there is still enough blood in the venous system particularly in the lower extremities. The overpressure which one can reach with these pilot suits allows a transport towards a hospital under good conditions but remains effective only for the extreme urgency of the initial shock. The fluid reanimation in an intensive care unit requires the monitoring with a central venous catheter and peripheral venous lanes for the careful perfusion of volumes of liquid to maintain an acceptable blood pressure around 80mmHg.

According to the french medical literature concerning the treatment of the SCLS by intravenous Immunoglobulines (IvIg), there are 2 different approaches: 1. preventive treatment (by monthly injection of Ig). 2. treatment of an acute crisis per perfusion of Ig as soon as the first symptoms appear. Which is the American experiment on this subject? Do You know how many Patients with SCLS profit from the treatment by IvIg in the USA? I am not informed of another Patient in Switzerland (7 million inhabitants) exept me. Which treatment do you have personally? I thank you for your answer.



As far as I know, there is no ongoing “American experiment” using IVIg either during acute episodes or for prevention purposes. There are 4 reasons for this: 1) Dr. Greipp of the Mayo Clinic, the country’s leading authority on SCLS with whom everyone consults, has not endorsed it; 2) no long-term, convincing study of experimental treatments (in Europe) has been published as of yet; 3) IVIg infusions often lead to unpleasant and costly medical complications; and 4) last but not least, the cost is prohibitive (at least $10,000/injection) and no U.S. insurance company is likely to cover it unless conditions 1-3 have been met. Thus, most patients take various combinations and dosages of Theophylline, Terbutaline and a leukotrine antagonist like Singulair to minimize the frequency and severity of episodes, and are given stress doses of steroids (e.g., Prednisone) as early as possible during an episode.
