A review of pathogens causing lower respiratory tract infection in the pediatric hematopoietic stem cell transplant recipient.

Pediatric hematopoietic stem cell transplant recipients are at risk for acquiring a variety of lower respiratory tract infections (LRTI), which result in frequent pediatric intensive care unit admission with high mortality. Recent advances in conditioning regimens, opportunistic infection prophylaxis, diagnostic tools, and treatment modalities have broadly impacted our understanding of LRTI among these vulnerable patients. In this review, the most common bacteria, viruses, and fungi causing LRTI in pediatric hematopoietic stem cell transplant patients are discussed.
