Dear Dent mothers, fathers and patients, We have worked hard to create the survey at RDCRN (Rare Disease Clinical Research Network - NIH sponsored). No good response yet - only about 10 patients finished. Link below, please consider!!! https://www.rarediseasesnetwork.org/cms/rksc/Get-Involved/Contact-Registry This is an easier, faster form of research and allows people from all over the world to do it. You will be asked to join contact registry and then do the survey. Good luck! Takes 10 min for moms and a little longer for patients - parents can do that one as well, even if kids are over 18! Please remember, the outcomes of this disease depend on your participation. It is a slow process, but if there is no process, there will be no outcome. My warmest regards, Lada

HI Val - not been on the site for a while. How is FJ doing? We met in London 2 years ago. My son is now 14 and has been on potassium citrate for several years now. His kidney function is stable and well maintained with no sign of stones as yet. Best wishes. K

Thanks you, Minu. That is very helpful and encouraging news. Sorry your husband has had problems too. FJ has always had stones, but fortunately they haven't caused him problems so far. Interestingly, he has never been prescribed or taken potassium citrate.

oxalates Created by emilysorenson

No, restriction is advised only if oxalate is elevated. The elevation could also be a result of calcium restriction in diet. Calcium should not be restricted. If less calcium is eaten, more oxalate is absorbed. My view is that possibly Dent patients do not get enough phosphorus, that is why I am studying phsophate regulating hormones for Dent in my FGF Study for Dent disease. We will hopefully learn something from it. I have just looked up our registry data. Few patients have oxalates in 50-60 range. Not most common but possible. Lada

Do you recommend a low oxalate diet in Dent's even if the oxalate level is normal?

Posted by LadaBL
21 Jan 2015, 09:39 PM

High oxalates are not common for Dent. However, sometimes even levels this high can come from dietary sources, but you could have him tested for primary hyperoxaluria. It is very important to minimize oxalate in diet. Did you review it with the nephrologist or a nutritionist? High doses of vitamin C can also give you high oxalate, make sure he is not getting that. We also have a center for primary hyperoxaluria if you would need genetic testing. Where did you get with this so far? Lada

Glad to hear, Jay. So from now on you will no longer take allopurinol? Any concerns? Besides potassium citrate, that is the only med Daniel has been taking since he was diagnosed at the age of three.

Posted by jgustafson
10 Sep 2014, 09:32 PM

As of my labs today, the numbers have now gone completely back to normal, so the allergist is pretty certain it was related to the allopurinol. As for the results, I think your correct in your assumption that this is not something the doctors normally test for. In my monthly labs they test for overall White Blood count, so when they saw it was elevated, they then checked to see what type of White Cell was elevated. I did not feel any symptoms, which made things even more confusing for the docs, as my numbers were through the roof. (Eosiniphil Count was 11,000 when normal range is 0 - 500).

Posted by minu
9 Sep 2014, 02:53 AM

Hi Jay. I hope you are doing well and that your levels are OK. I know Daniel takes similar meds to you, including allopurinol, I checked his lab history and I do not think he has ever had elevated eosiniphils, but, to be honest, I am wondering if they have ever checked them, as they are listed on the sheet but it is all blank. Or it says 0.0. Is it normal for the level to be zero? The doctor once took him off allopurinol when he was a teen, but I requested to put him back on it, because those two years Daniel's kidney functioned dropped more rapidly. Have you felt any symptoms/ill because of the high level of white blood cells?

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.

Visit sanfordresearch.org/CoRDS to enroll.

Hi,

 

 

I am a nephrologist (kidney doctor) who works at NYU in New York City. National Institutes of Health has sponsored research of Dent disease starting Sept 2009 which includes, and starts with, forming Registry of Dent disease patients.

 

 

Dent disease manifests usually with low molecular weight proteinuria (loss of protein in the urine) and often with kidney stones or even calcifications of kidney. Significant number of patients develop kidney failure and need dialysis or transplantation.

 

 

Registry means collection of information on individual patients which is then stored, anonymously, in one database. That allows us to analyze collected information on large group of Dent patients, which has never been done before, because physicians typically take care of only few Dent patients (usually 1-5).

 

 

Our website is http://www.rarekidneystones.org/dent, where you can look up the available information.

Hi Lada. How are you?

 

I just saw te question from Mari Carmen from Sevilla in Spanish. I don't know hoe long ago she wrote but I can translate.

 

 

".Hi Lada. My 14 year old son has been diagnosed with Dent 1. He has losses of calcium, proteinura and hematuria. They are only giving him acalka and now Vitamin D. But he is not as tall as he should be for his age, and now two small bumps have come out on his chest. The doctor says this is normal growth but I am very concerned. Thanks for your answer.

Answer

Thanks. You can answer her that growth delay is common in Dent disease and that sometimes children get treated with growth hormone.

 

 

Best,

Hi Carmen,

 

 

I do not speak Spanish, unfortunatelly.

 

If you were asking if it was expected to have high calcium in the urine for Dent patients, I can tell you that it is very common.

 

 

Maybe you can find somebody to translate to English?

Lada,

 

I have a question about Dent's Disease & its progression. I realize you can't predict what is going to happen with my son, but I am curious as to whether you have heard/seen any trends with regard to its progression. My son, Matthew, turns 15 years old next week. His creatinine is 1.2 as of today & he weighs approximately 114. His creatinine has been going up .1 for the past 4 labs. He has labs every 3-4 months. At this rate, if it keeps progressing at this rate, he will need a transplant before he reaches 20. I am very concerned. Are there any statistics? Could puberty cause the creatinine to increase at a faster rate & then maybe it may slow down as he gets older? What is the average age of transplant with this disease? Is there anything that has been found to slow the progression? Another thing.....can a carrier be a potential kidney donor? I have 4 daughters & 3 of them are Dent's carriers. Thank you so much for your time.

Answer

Dear Rosemary,

 

 

I would not worry about the transplant at this time, his kidney function is very good.

 

Carriers could theoretically be donors, however we are not sure if we recommend it or not.

 

If the donor has proteinuria or stones, it is probably not such a good idea. It has been done, however.

 

It would have to be decided on case to case bases by a transplant center.

 

 

As the child grows and gains muscle mass, the creatinine could increase.

 

Citrates have been shown to decrease progression on mice, nothing known with certainty on humans.

 

ACE inhibitors when significant albuminuria potentially beneficial, no data.

 

Thiazide diuretics? Unknown if affect progression.

 

You see, patients are asking us for advice but we have no data and cannot recommend.

 

Then we try to get data but patients are reluctant to participate in research!

 

And we go in circles.

 

In our study we are trying to see if phosphorus could be beneficial in reducing calcium in urine, kidney damage instead of thiazides that have side effects often difficult to tolerate.

 

 

Regards,

 

We could talk on the phone this weekend, or Fri pm if you like, since this is so complex.

 

My cell is 917-572-6379

My 8 year old son and my 32 year old brother both have Dent's, and my brother has recently been placed on dialysis due to renal failure, and he is currently on the transplant list. I am a carrier of dent's, and have mild symptoms, excess protein in the urine, have had kidney stones several times, Am I a canidate to donate a kidney to either of them if I am a match?

Answer

This question has really not been answered properly as of yet.

 

 

We have heard of a mother who has donated the kidney to her son and both were doing well, however there is no clear recommendation.

 

 

If you actively form stones, and have significant stone on CT and have significant proteinuria, that is probably not a good idea.

 

I would say, you don't have absolute contraindication but a relative one and you would have to be evaluated by a transplant center.

CaraM120 Message
29 Jan 2014, 06:52 PM

Hi Lada,

 

Thank you for responding to my earlier question. My son is 8years old, and we have since stopped the enalapril because it was having absolutely no effect on him and was making him feel bad. We recently discovered that my brother, who is 32, has Dent's also, and he is in kidney failure and will be started on dialysis soon. We are hoping this is not typical and this is not the path that my son will go down. Does kidney failure usually onset this quickly with Dents pts? Our son is on the dent's registry and we are willing to enroll him in the study and I'm sure my brother would participate also.

Answer

It is quite common that the older relative gets a diagnosis only after a child is diagnosed.

 

This is a rare disease more unusual in children and pediatricians are better in making the diagnosis.

 

 

It is in the expected age range that your brother developed advanced kidney failure, however an early part of that age spectrum. Usually for Dent, dialysis is needed between 30 and 50, so this was early.

 

 

Our goal is to study more the disease and test interventions that could delay the progression of the disease. That is why we are doing this study.

 

 

The good news is that just because they have the same mutation, the disease does not have to behave in the same way in the two of them. Variability in the family is quite common.

 

 

I am glad you are in the registry. As soon as our consent form for children is approved, I will let you know. Unfortunatelly, for now we are not testing the patients with advanced disease if they have high PTH (parathyroid hormone) and your brother likely has it above normal. You can ask him if he knows, but he should definitely be in the registry for any further research and for better understanding of disease.
