Dear Knackll:
I'm so terribly sorry to learn of your awful ordeal! However, if your misery wants some company, I can assure you that yes, plenty of others in this community have also suffered a series of terrible episodes leading to permanent damage to extremities and/or vital organs -- and even to death.
Here are some suggestions for the two of you:
1) Have your hospital send to Dr. Druey at NIH refrigerated blood from the day of your wife's admission. (They usually keep any blood drawn for a week.) Her blood needs to be studied with the powerful tools available at NIH to determine what (if anything) is wrong -- or especially wrong -- with her. For instructions on how to ship the blood, which must be chilled but not frozen, have the hospital contact Dr. Druey and/or his team, see "Disorder Details" in this site, and scroll towards the bottom for contact information. And do this every time she lands in the hospital.
2) If she indeed has been properly diagnosed as having SCLS, and if her doctors are going to give an IVIG therapy a fair try, then they must give her the recommended dose of 2 gr/kg/month during two consecutive days. In other words, if she weighs 60 kilograms, she should get 60 grams on Day 1 plus 60 grams on Day 2. If it is true that she was started on a dose of 30 grams of IVIG, whether for one or two days, she was seriously shortchanged -- unless she weighs in at 15 or 30 kilos, of course! If you wish, insist that her current doctor consult with an immunologist; they are most familiar with IVIG and how to administer it.
3) Have her doctors make arrangements to have your wife seen at NIH (in Bethesda, MD, just outside Washington DC) as soon as possible. For this purpose, they must contact Dr. Druey and send him all of her medical records along with a referral letter. Dr. Druey will be able to confirm her SCLS diagnosis, or else he will have her examined by his colleagues until the right diagnosis is obtained.
