Fibrosing cholestatic hepatitis in a kidney transplant recipient with hepatitis C virus.

Fibrosing cholestatic hepatitis (FCH) is a fatal disorder that presents as a progressive deterioration of liver function over a period of several weeks to several months. It is caused by the direct cytotoxic effect of the over-expression of viral antigens on hepatocytes in immunosuppressed patients. Our patient was a 59-year-old man with hepatitis C virus (HCV) infection of genotype 2a who had suffered from end-stage renal disease due to diabetic nephropathy and underwent kidney transplantation. His serum total bilirubin levels gradually increased to 20 mg/dl and liver atrophy progressed during several weeks after kidney transplantation, which was initially difficult to distinguish from drug-induced liver injury. We diagnosed the condition as FCH on the basis of pathological findings and increased HCV viral load, and treated the patient with Glecaprevir/Pibrentasvir. However, the patient died of refractory hemorrhagic gastric ulcer and liver failure. Currently, it is possible to treat infections of all genotypes of HCV, even with end-stage renal disease, with direct acting antivirals. Furthermore, it is preferable to treat HCV before kidney transplantation considering the risk of FCH due to immunosuppressive therapy.
