Selective thrombocytopenia and neutropenia occurring after bone marrow transplantation--evidence of an auto-immune basis.

This study shows that hitherto unexplained thrombocytopenia and neutropenia occurring after bone marrow allografting and autografting may have an immune basis. In the case of autografts, such antibodies are, by definition, auto-antibodies, and it is suggested that similar antibodies occurring after allografting are also auto-immune.
