Long-term survival after bone marrow transplantation: a 15-year follow-up report of a patient with Wiskott-Aldrich syndrome.

In 1968 a 2-year-old boy with Wiskott-Aldrich syndrome was extremely ill with eczema, a series of life-threatening infections, and repeated hemorrhages into his skin, lungs, brain, and other internal organs. He was given high-dose cyclophosphamide therapy for immunosuppression, followed by bone marrow cells from his histocompatible, healthy sister. In the 15 years since bone marrow transplantation, he has had full T cell, partial B cell, and no hematopoietic engraftment. He has weathered the usual infectious diseases of childhood, has had no serious infections, and despite persistent thrombocytopenia has not had serious bleeding episodes.
