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

[Richard Wasserman]

I suspect every Pedi GI group has their preference but my patient was
induced with prednisone and 6MP and has done very well. When 6MP was stopped
several years ago he relapsed but was reinduced and has continued to do well
on 6MP having weaned off steroids.
