Gigi, we have one we transplanted successfully many years ago. Mort

We have collected several families and have just proceeded with whole exome sequencing. Please, do not hesitate to contact me if you would like to collaborate (would need high molecular weight DNA from patient parents and healthy fraternal twin.

A few days later was taken to OR and found to have dozens of intestinal atresias and webs now s/p multiple OR procedures with almost no small bowel remaining, on small bowel transplant list.  Currently TPN dependent.  She has had multiple admissions with fever (15-20 episodes) and variably has had central line infections, UTIs (on 2-3 occasions), G tube site infection, and most recently fungemia (candida).  Her most severe infection was E coli sepsis leading to ARDS, from which she recovered.  She has had coag neg staph, E faecalis, E cloacae, E coli grow from blood cultures in past but on several occasions her cultures have been negative.  No history of recurrent sino-pulmonary infections, otitis media, skin infections/abcesses.  She is not on steroids or immunosuppressives.  She is on methadone and also gets some IV atarax for itching.  No family history of known immunodeficiency though her mom thinks maybe she (Mom) was on IVIG for a year or so around age 1-2.  Mom currently has no issues with infections. Patient got the Varicella vaccine and subsequently developed chicken pox.  In addition she subsequently had an episode of shingles as well.

In addition we expect that with PLE she would have functional antibody responses and functional T cells, which is not the case.  Overall her pattern of infections is not consistent with a humoral deficiency.  In fact you could argue that all of her infections were nosocomial in nature (line infections, UTIs, fungemia on TPN) except for her varicella after vaccination.  Interestingly, when reviewing the literature we were able to find reports (<10) of multiple intestinal atresia associated with immunodeficiency.  Most die in infancy of sepsis.  It was suggested there was a possible hereditary component as one family had 2 siblings with the condition.  Wide range of immune defects reported from functional lymphopenia to SCID like with GVHD after a blood transfusion.

Have not yet assessed ADA/PNP activity, but wondering about that as well as looking for other leaky SCID etiiologies.  Any other thoughts? She is currently on the small bowel transplant list but the transplant team is  understandably concerned she won’t do well post transplant  and we all would like to clarify her immune defect if possible .  Thank you again for your help.
