Diagnostic Performance of Hemophagocytic Lymphohistiocytosis Criteria and HScore in Critically Ill Patients With Severe Hemophagocytic Syndrome

OBJECTIVES: To assess whether critically ill hematologic patients without diagnosis of hemophagocytic lymphohistiocytosis may have features mimicking hemophagocytic lymphohistiocytosis according to both diagnostic scores. DESIGN: A retrospective case-control study. SETTING: Hemophagocytic syndrome diagnosis was standardized and based on a consensual diagnosis by at least two experts of a university hospital which is a reference center for hemophagocytic syndrome. PATIENTS: Cases (hemophagocytic syndrome+) consisted in a group of consecutive patients (n = 150) admitted in our ICU between 2007 and 2018. Control group (hemophagocytic syndrome–) consisted in patients included in a prospective multicenter cohort of hematologic patients in whom three independent experts ruled out the diagnosis of hemophagocytic syndrome (n = 1011). MEASUREMENTS AND MAIN RESULTS: Overall, 1,161 patients were included. Hospital mortality was 45.8% in hemophagocytic syndrome– patients (n = 66) and 38.8% in control patients (n = 392; p = 0.126). Median HScore was 235 (205–262) in hemophagocytic syndrome+ and 42 (18–62) in hemophagocytic syndrome– patients (p
