OBJECTIVE: To share experience of over 15 years in hematopoietic stem cell transplantation in children with primary immunodeficiency disorders.
DESIGN: Medical record review.
SETTING: A referral center for pediatric hemato-oncological disorders.
PARTICIPANTS: Children (<18 y) diagnosed to have primary immune deficiencies who underwent hematopoietic stem cell transplantation between 2002 and August 2017.
MAIN OUTCOME MEASURES: Disease-free survival, morbidity and mortality.
RESULTS: 85 primary immunodeficiency disorder transplants were performed with engraftment noted in 80 (94%) transplants and an overall survival of 67%. The conditioning regimen was individualized based on the underlying immune defect. Mixed chimerism was noted in 20% children with 56% (9/16) remaining disease-free. Graft versus host disease was noted in 33 (39.2%) children with most seen in children with chronic granulomatous disease. Severe combined immune deficiency transplants were mainly complicated by infections. Immune cytopenias complicated Wiskott Aldrich syndrome and Hemophagocytic lymphohistiocytosis transplants. 29.4% (25/85) children underwent haploidentical transplant in our cohort with a survival of 70% in this group. Infectious complications were the most common cause of death.
CONCLUSIONS: Primary immunodeficiency disorders are curable in India when transplanted in centers with experienced and trained pediatric transplant physicians and intensivists.
