Daclatasvir and Asunaprevir Combination Therapy-induced Hepatitis and Cholecystitis with Coagulation Disorder due to Hypersensitivity Reactions

摘要

A 70-year-old woman with chronic hepatitis C was admitted to our hospital due to liver injury, cholecystitis, and disseminated intravascular coagulation with a fever and skin rash. She had been on a combination regimen of daclatasvir and asunaprevir for 2 weeks of a 24-week regimen. Because of the symptoms, laboratory findings, results of a drug-induced lymphocyte stimulation test, and pathological findings of liver biopsy, we diagnosed her with drug-induced liver injury. Although daclatasvir and asunaprevir combination therapy is generally well-tolerated, some serious adverse effects have been reported. Our findings indicate that immunoallergic mechanisms were associated with daclatasvir and asunaprevir-induced liver injury.
