Unrelated donor and HLA-identical sibling haematopoietic stem cell transplantation cure chronic granulomatous disease with good long-term outcome and growth.
Chronic granulomatous disease (CGD) causes recurrent infection and inflammatory disease. Despite antimicrobial prophylaxis, patients experience frequent hospitalisations and 50% mortality by 30 years. Haematopoietic stem cell transplantation (HSCT) can cure CGD with resolution of infection and colitis. This study reports the survival and long-term outcome in 20 conditioned patients treated between 1998 and 2007, using 10 matched sibling (MSD) and 10 unrelated donors (URD). Age at HSCT, graft-versus-host disease (GvHD), growth, and outcome were analysed. Fourteen had > or = 1 invasive infection, 10 had colitis and seven had growth failure before HSCT. Median age at transplantation was 75 months (range 15 months-21 years). Eighteen (90%) were alive 4-117 months (median 61) after HSCT with normal neutrophil function. Two died from disseminated fungal infection. Two experienced significant chronic GvHD, with continuing sequelae in 1. Colitis resolved within 8 weeks of HSCT. Mean weight and height for age Z scores on recovery from HSCT rose significantly (P < 0.001). HSCT with MSD or URD gave excellent engraftment and survival, remission of colitis and catch-up growth, with low incidence of significant GvHD. Transplant-associated complications were restricted to those with pre-existing infection or inflammation, supporting the argument for early HSCT for more CGD patients with a well matched donor.
