Successful treatment of hemophagocytic lymphohistiocytosis in a trauma patient: a case report
Year: 2025

Study design: Case Report
Abstract: Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hyperinflammatory syndrome characterized by excessive activation of the immune system. This case report describes an unusual presentation of HLH triggered by severe trauma from a motorcycle accident, which is a departure from traditional associations with infections, malignancies, or autoimmune conditions. A 40-year-old man with multiple traumatic injuries developed persistent fever, pancytopenia, and elevated inflammatory markers following orthopedic surgery. Despite empiric antibiotic therapy, his condition deteriorated, exhibiting high fever, skin rash, hepatic dysfunction, and marked elevation of ferritin levels (32,901 ng/mL). Bone marrow biopsy confirmed the diagnosis of HLH, and treatment was initiated according to the HLH-2004 protocol, which included methylprednisolone, intravenous immunoglobulin, and immunosuppressive therapy. The patient demonstrated significant clinical improvement and was discharged after 37 days, with no recurrence observed during the follow-up period. This case underscores the need to consider HLH in trauma patients presenting with unexplained inflammatory responses and illustrates that prompt diagnosis and aggressive treatment can lead to successful outcomes.
