Bronchiolitis Obliterans Syndrome Following Pediatric Hematopoietic Stem Cell Transplant

Publication Date: June 18, 2024

Key Points

Key Points

  • Pulmonary complications occur frequently following pediatric hematopoietic stem cell transplant (HSCT).
  • Pulmonary complications are a significant contributor to morbidity and mortality, affecting 25% to 60% children following HSCT and causing 25% to 65% of non-relapse mortality.
  • The most common non-infectious pulmonary complication following HSCT is bronchiolitis obliterans syndrome (BOS), a manifestation of lung chronic graft vs. host disease (cGvHD) affecting 4.5–8.3% of children post-HSCT.
  • Given that initial phases of BOS are often asymptomatic, surveillance with pulmonary function testing (PFT) is recommended.
