Allogeneic hematopoietic stem cell transplantation (HSCT) is a feasible treatment option for Gaucher disease (GD). Among 60 patients diagnosed with GD over 15 years (2004-2019), three children who underwent HSCT (January-November 2017) were analyzed. Two boys (cases 1 and 2) and one girl (case 3) received HSCT at 3, 7, and 10 years of age, respectively. Cases 1 and 3 received haplo-HSCT, while case 2 received HLA-identical related-donor transplantation. The CD 34 cell dose was 5-10×106/kg. Neutrophil and platelet engraftment were between days +14 to +21 and days +15 to +76. Post-HSCT chimerism was a 100% donor. None of the patients developed acute or significant chronic graft versus host disease (GVHD). All patients had febrile episodes with negative blood cultures. Major post-HSCT complications included EBV-viremia and recurrent lobar pneumonia in case 1, delayed engraftment and pure red cell aplasia (PRCA) in case 2, and pericardial effusion with tamponade in case 3. At a median of 49 months post-HSCT, all patients were stable with improved growth, absent organomegaly, and had completed immunization. The median cost of treatment was $23,038.96, which is 10.7%-13% of the yearly enzyme replacement therapy (ERT) cost. In a resource-limited setting like India, ERT is a financial burden and not a sustainable option. With improved treatment outcomes, haplo-HSCT is now a possible option for almost every patient, even if no HLA-identical donor is identified.
