The diagnosis is often delayed due to overlapping clinical manifestations with infection, rejection, or malignancy, and management becomes particularly challenging when accompanied by severe hepatic dysfunction. Here, we describe a pediatric patient who developed Epstein\u2013Barr virus (EBV)\u2013associated secondary HLH following liver re\u2010transplantation for biliary atresia. On postoperative Day 10, the patient presented with high fever, cytopenia, hypertriglyceridemia, hypofibrinogenemia, and marked hyperferritinemia, accompanied by rapidly worsening liver injury. Bone marrow biopsy confirmed hemophagocytosis. Given the severe hepatic impairment and persistent inflammation, the patient received three doses of emapalumab (1\u2009mg\/kg), a monoclonal antibody blocking interferon\u2010\u03b3, combined with corticosteroids, intravenous immunoglobulin, and antimicrobial prophylaxis. The treatment led to a rapid decline in ferritin levels, reversal of liver dysfunction, and complete clinical recovery without opportunistic infections. The patient has remained stable with normal liver function and negative EBV DNA for over 2 years of follow\u2010up. This case demonstrates that early interferon\u2010\u03b3 blockade can safely and effectively reverse HLH\u2010related liver injury after transplantation, offering a promising therapeutic strategy for the management of secondary HLH complicated by severe hepatic dysfunction.<\/jats:p>","DOI":"10.1002\/jpr3.70126","type":"journal-article","created":{"date-parts":[[2025,11,30]],"date-time":"2025-11-30T06:05:56Z","timestamp":1764482756000},"page":"14-18","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Interferon\u2010gamma
