Successful bone marrow transplant for Fanconi's anaemia.

A 15-year-old boy with Fanconi9s anaemia, who required four units of blood each month, received a bone marrow graft from his 9-year-old brother, who has HLA identical and compatible on mixed lymphocyte reaction. Considerable immunosuppression was used and bacterial infection was prevented by vigorous decontamination in a Vickers-Trexler isolator. After the graft the patient9s blood counts remained satisfactory for nine months, but it took six months before qualitative immune function was normal.
