Abstract

Abstract:

Objective To analyze the clinical characteristics and prognostic factors of hemophagocytic syndrome (HPS) in children. Methods A retrospective analysis was conducted on the clinical data and follow-up information of 45 children with HPS admitted from January 2017 to July 2023. Results The median age of onset in the 45 children was 4.5 (2.1-10.0) years, all of whom started with fever. Infection-related HPS accounted for 77.8%, with Epstein-Barr virus (EBV) infection being the most common (85.7%). The overall survival rate of all children was (88.9±4.7)%. Univariate analysis showed that triglycerides≥3.8 mmol/L and lactate dehydrogenase≥2500 U/L were risk factors affecting the prognosis of children with HPS (P<0.05 for both), and multivariate analysis showed that triglycerides≥3.8 mmol/L was an independent risk factor affecting the prognosis of children with HPS (P=0.029). Conclusion HPS often starts with fever, and infection (especially EBV infection) is the most common cause; the levels of triglycerides and lactate dehydrogenase at initial diagnosis (especially triglycerides≥3.8 mmol/L) are key factors in assessing prognosis.

Key words: hemophagocytic syndrome, clinical characteristics, treatment, prognosis, child
