A review published in the Lancet in 1993 suggested that type 1 diabetes in a bone marrow allograft donor might be transmitted to the recipient after a successful transplant. A 21- year follow-up report of this study after a successful allograft for aplastic anemia indicated that the recipient had developed a number of antibodies against pancreatic islet cells, and although these persisted for a number of years, she did not develop diabetes. The donor had type 1-diabetes at the time of transplant.
In a bone marrow transplant that occurred in 1979, the donor had been diagnosed with type 1 diabetes seven years prior to transplantation, and was negative for islet cell antibodies (ICAs). Overtime, the recipient developed ICAs and high levels of anti-GAD (glutamic acid decarboxylase) antibodies. The patient also had chronic GVHD (Graft versus host disease), a condition in which multiple autoantibodies are commonly found. The presence of ICAs and anti-GAD antibodies might not be related to the fact that the donor had type 1 diabetes. Alternatively, the autoimmune process observed in the recipient may have been modified by the Azathioprine therapy, which was in place for 6 years immediately post-transplant. Blood glucose measurements over the past 21 years have shown no evidence of type 1 diabetes.
