Early diagnosis and treatment resolved cholestatic hepatitis C without fibrosis after living donor liver transplantation: Report of a case

Treating fibrosing cholestatic hepatitis C with sofosbuvir and ribavirin: a matched analysis

BACKGROUND

Fibrosing cholestatic hepatitis (FCH) is an uncommon but potentially fatal complication of recurrent hepatitis C (HCV) in liver transplant recipients.

METHODS

We matched the treatment outcomes of 10 liver transplant recipients who developed FCH with those of 10 recipients with recurrent HCV without FCH treated with sofosbuvir and ribavirin.

RESULTS

Baseline mean alanine transaminase, aspartate transaminase, alkaline phosphatase, and total bilirubin were 186 U/L, 197 U/L, 243 U/L, and 6.7 mg/dL, respectively, in the FCH recipients and 82 U/L, 60 U/L, 110 U/L, and 0.99 mg/dL, respectively, in non-FCH recipients. The sustained viral response in FCH and non-FCH recipients was 40% and 80%, respectively. One-yr patient and graft survival rates were 90% and 80%, respectively, in FCH recipients, and 100% in non-FCH recipients. Seven FCH and six non-FCH recipients were treated for anemia with blood transfusion and/or erythropoietin growth factors.

CONCLUSION

Our results suggest that the use of sofosbuvir and ribavirin is effective and tolerable in liver transplant recipients treated for recurrent FCH. There is a trend of lower sustained viral response, patient survival, and graft survival in the FCH recipients.

Fibrosing cholestatic hepatitis developing within one month after living donor liver transplantation for chronic hepatitis C-related cirrhosis: a case report

Fibrosing cholestatic hepatitis (FCH) is a life-threatening consequence of hepatitis C virus (HCV) infection occurring in a small minority of liver transplantation (LT) recipients. We herein report a case of early-onset FCH after living donor LT in a 47-year-old woman with HCV-related cirrhosis. The patient underwent balloon-occluded retrograde transvenous obliteration of a splenorenal shunt to treat an impaired portal flow on the sixth postoperative day (POD 6) and a bypass operation for hepatic artery thrombosis on POD 12. Thereafter, the serum bilirubin levels increased gradually; however, computed tomography revealed no evidence of biliary stricture. The serum HCV-RNA level on POD 27 was >7.8 log IU/mL. Histopathology of a needle graft biopsy performed on POD 28 revealed FCH with extensive portal fibrosis accompanied by mild inflammation, hepatocyte ballooning, and ductular proliferation with cholestasis. The patient received combination therapy with pegylated interferon, ribavirin, and double-filtration plasmapheresis for the treatment of early-onset FCH. Both the recipient and the donor carried the major genotype single nucleotide polymorphism (TT) at rs8099917 near the interleukin-28B gene. Furthermore, the HCV genotype was treatment-sensitive 2a. Nonetheless, the recipient died of hepatic failure on POD 211. Thus far, few cases of FCH occurring within 1 month after LT have been reported. In addition, the early onset of FCH may be an adverse prognostic factor.

Cholestatic hepatitis C following liver transplantation: an outcome-based histological definition, clinical predictors, and prognosis

Cholestatic hepatitis C virus (HCV) is a rare form of recurrent HCV following liver transplantation (LT) without specific diagnostic criteria. An outcome-based method to improve its diagnosis and a description of its prognosis are needed. All 1-year post-LT protocol liver biopsy samples and biopsy samples initially reported to show cholestatic HCV from patients transplanted with HCV between February 2002 and December 2009 were reviewed for the inflammation grade, the fibrosis stage, and 4 cholestatic HCV features: ductular proliferation, canalicular cholestasis with or without intracellular cholestasis, hepatocyte swelling with or without lobular disarray, and sinusoidal/pericellular fibrosis. We used patient and graft survival to define histological criteria for cholestatic HCV, and compared the clinical features of these patients to those of patients with minimal or significant post-LT fibrosis. One hundred seventy-nine patients were analyzed, the median age was 56 years, and 73% were male. Patients with 3 or more of the 4 cholestatic HCV criteria had significantly worse survival (log-rank P < 0.001) regardless of the fibrosis stage, and this was used as our novel definition of cholestatic HCV. Using this definition, we found that 27 patients (15%) had cholestatic HCV, 53 (30%) had significant fibrosis (stage ≥ 2/4), and 99 (55%) had minimal fibrosis (stage < 2/4). The final model for clinical predictors of cholestatic HCV included donor age [odds ratio (OR) = 1.37 per decade, P = 0.04] and previous rejection (Banff grade ≥ 5; OR = 4.19, P = 0.002). Total bilirubin was the strongest laboratory predictor of cholestatic HCV (area under the curve = 0.93), whereas the HCV viral load was not a significant predictor. The final model of post-LT survival included the pathology group {cholestatic HCV [hazard ratio (HR) = 6.07, P < 0.001] and significant fibrosis (HR = 2.53, P = 0.02)}, donor age (HR = 1.49 per decade, P < 0.001), and cold ischemia time (HR = 1.11 per hour, P = 0.02). In conclusion, we propose diagnostic criteria for cholestatic HCV that include specific criteria (the presence of at least 3 of the 4 histopathological features on biopsy) and other supportive and exclusionary criteria. Older donor age and rejection increase the risk of cholestatic HCV, and an elevation in the total bilirubin level may help to identify these patients. These criteria must be validated prospectively.
