Efficacy of high ‐dose steroids for bronchiolitis obliterans syndrome post pediatric hematopoietic stem cell transplantation

Abstract BOS is the pulmonary manifestation of cGvHD post‐allogeneic HSCT. Survival and treatment of this often fatal complication have not improved over the last 20 years and there is no clear standard of care. For the past 10 years, BOS was treated in our center with monthly cycles of HDPS. We reviewed the outcomes of patients with post‐HSCT BOS who met the diagnostic criteria for BOS as per the NIH consensus and were treated with at least one cycle of methylprednisolone at a dose of 10‐30 mg/kg/d×3 d. We collected demographic and clinical data, responses to treatment and results of pulmonary function tests at several time points. Between January 2007 and January 2014, 12 patients were treated with HDPS for post‐HSCT BOS. Five patients (42%) had a good response to treatment; four patients (33%) stabilized with moderate lung disease; and three patients (25%) progressed to end‐stage disease. No significant acute side effects attributable to the HDPS treatment were identified. HDPS may be an effective treatment option for all but the most severely ill patients with post‐HSCT BOS.
