[PAGID] complications in XLA patient

[Ashish Kumar]

Yes, XLA was confirmed by gene testing; pedigree has a classic X-linked 
inheritance pattern with several male deaths in early childhood, and he 
has no B-cells. He has had PCR testing for all the viruses known to 
cause hepatitis for which testing is available; also for 
schistosomiasis. Unfortunately, I don't have any information on the 
plasma he received until 2003 in Vietnam, except that he received it 
monthly starting at age 10.
