Transplantation of allogeneic stem cells is currently the only curative treatment for some nonmalignant pediatric diseases. We investigated whether transplantation of purified CD34(+) stem cells prevents acute and chronic GvHD and reduces transplant-related mortality. A total of 25 pediatric patients with nonmalignant diseases underwent allogeneic transplantation from 26 donors (matched related n=4, matched or partially matched unrelated n=14, mismatched related n=8). All grafts were purified peripheral-blood CD34(+) stem cells mobilized with G-CSF. Patients received a median of 12.9 x 10(6) CD34(+) progenitor cells with a median of 6.1 x 10(3) contaminating T-lymphocytes per kilogram of body weight. No post transplant immunosuppressive drugs were given for prophylaxis of GvHD. Engraftment was seen in 21 patients. Three patients engrafted after a second transplant and one patient failed to engraft. Two patients had autologous reconstitution 1.5 years post transplant and one of them was successfully retransplanted. No acute GvHD >grade II was seen, and only two patients developed limited, chronic GvHD. In all, 22 patients (88%) are alive with a median follow-up of 3.7 years. In total, 19 patients (76%) are free of disease or of progression. Transplantation of highly purified peripheral-blood CD34(+) stem cells is associated with low toxicity in patients with nonmalignant diseases.
