Serum ferritin is a good indicator for predicting the efficacy of adult HLH induction therapy

Abstract

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical syndrome with a high mortality rate. There is no biomarker to predict the early therapeutic response. Objective: Our study explores the significance of serum ferritin in predicting the response of induction therapy. Methods: We retrospectively analyzed the clinical data of 102 adult patients with HLH admitted to our hospital. These patients received HLH-94 regimen for induction therapy. The patients were divided into remission group and non-remission group according to the response of induction therapy. Results: Ferritin values between 1–4 weeks post induction were predictive of remission (p
