Diagnosing and Grading of Sinusoidal Obstructive Syndrome after Hematopoietic Stem Cell Transplant of Children, Adolescent and Young Adults treated in a Pediatric Institution with Pediatric Protocols

Sinusoidal obstructive syndrome (SOS), previously known as hepatic veno-occlusive disease (VOD), has been recognized as a complex and life-threatening complication following hematopoietic stem cell transplantation (HSCT). SOS is a complication that develops after injury to the micro-vasculature and endothelial cells of the liver. Damage to endothelial cells promotes increased expression of pro-inflammatory cytokines and adhesion molecules in the vascular endothelium, leading to sinusoidal narrowing and micro-vascular occlusion, altered liver cytoskeletal architecture, weakened intercellular junctions, and further liver damage.
