Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare, life‐threatening condition caused by genetic mutation or various triggers disturbing the immune system. Methods: A multicenter retrospective study of pediatric patients with HLH receiving a diagnosis between January 2005 and December 2019 from three pediatric oncology centers was conducted to explore the clinical characteristics and determine prognostic factors associated with outcomes among Thai children. Results: In all, 78 patients with HLH with a median age at diagnosis of 3.17 (range,.08–17.83) years were enrolled. The male to female ratio was 1.2:1. The most common type of HLH was infection‐associated hemophagocytic syndrome (IAHS) (n = 59, 75%) of which Epstein‐Barr virus was the most common pathogen. Thrombocytopenia, hyperbilirubinemia, and treatment response at weeks 2 and 8 after initiating treatment were associated with mortality. Platelet count <50,000 cells/mm3 was the only independent prognostic factor to define survival outcome (p‐value.035). Two‐year overall survival rate was 71.3% (95% confidence interval, 59.2%–80.3%). Survival rates between IAHS, malignant associated HLH, macrophage activation syndrome, and unspecific HLH did not significantly differ (p‐value.571). Conclusion: IAHS was the most common cause among pediatric HLH in Thailand. The outcomes of Thai children with HLH were comparable to those of developed countries. Platelet count <50,000 cells/mm3 was the only independent prognostic factor to define survival outcome. [ABSTRACT FROM AUTHOR] |
