1531. A Twenty 3-Year Retrospective Study of Secondary Hemophagocytic Syndrome in a Pediatric Third-Level Referral Center in Mexico City

摘要

BackgroundSecondary hemophagocytic syndrome (SHS) may develop as a result of excessive immune activation, with proliferation of T cells and macrophages. It is often fatal and remains ill-recognized in children, leading to false or delayed diagnosis and suboptimal management. This condition has been described more often in association with virus, but it can be secondary to bacteria, fungi, and parasites.
