[CIS-PAGID] Duration of treatment for Crohn's in XLA

[Torgerson, Troy]

We have/had 3 patients with XLA and significant IBD that has been labeled as "Crohn's" disease - Jack's question of whether it is really Crohn's disease is a good one.  In general, the bowel disease does not improve with IVIG, even combining IVIG with oral IgG (yes, we tried it).  It does seem to improve with other immune suppression that is often used to treat IBD such as azathioprine but we have been very worried about suppressing T cell immunity after one of our patients developed degenerative CNS disease and was subsequently found to have astrovirus in the brain tissue.  Once the bowel disease starts, our experience has been that it is very difficult to get patients off their immune suppression because the bowel disease revs up again as meds are tapered.

Hans has told me a number of times that before the etiology of XLA was known, he used to do rectal suction biopsies on all of the XLA kids and virtually all of them had crypt abscesses even in the absence of overt gut disease - they often used this as one of the diagnostic clues.  It is intriguing to think about what might be different in the pathophysiology and histopathology of patients with bowel disease caused by lack of Tregs (IPEX) vs. that caused by lack of B cells (XLA) vs. that caused by lack of functional neutrophils (CGD).

Question out of relative ignorance! Why the surprise? Is Crohn's purely an autoimmune disease in the "classical" sense? And is it really Crohn's disease in the classical sense?

I was surprised too --- and have a good number of older ones!  It would be a
neat question and could be answered!
