title: Severe fever with thrombocytopenia syndrome presenting as acute hepatic failure.
abstract: Severe fever with thrombocytopenia syndrome (SFTS) is characterized by fever, thrombocytopenia, leukopenia, and altered consciousness, which may also involve multi-organ failure. Initially SFTS mortality was as high as 30%, when diagnosis remained unclear. We present a case of a 53-year- old man with SFTS presenting with acute hepatic failure. On admission, he presented with confusion, elevated serum liver enzyme and ammonia levels, whose serum markers were negative for acute viral hepatitis. He was diagnosed with SFTS based on reverse transcription-polymerase chain reaction identification of the SFTS virus M segment. Percutaneous liver biopsy was performed to identify the degree and extent of necroinflammation and patient prognosis. After recovery, he was followed-up for 12 months with no SFTS-related sequelae. A discordance in severity between biopsy findings and clinical course could explain the rapid clinical improvement. Atypical presentations with multi-organ failure can delay timely diagnosis and management of infected patients.
