Has Increased Rollout of Direct Acting Antiviral Therapy Decreased the Burden of Late Presentation and Advanced Liver Disease in Patients Starting Hepatitis C Virus Therapy in Germany?

Abstract

Goals and background: International guidelines recommend prioritized treatment initiation in hepatitis C virus (HCV)-infected patients with advanced liver disease. We aimed to evaluate whether the widespread usage of direct acting antivirals (DAAs) has led to a decrease in late presentation for care.

Study: Data derived from the multicenter German Hepatitis C Cohort (GECCO) was analyzed. Treatment naive HCV-infected patients initiating DAA-based treatment between January 2014 and September 2017 were included. Advanced liver disease was defined by aspartate aminotransferase to platelet ratio index score ≥1.5, METAVIR≥F3, or FibroScan ≥9.5 kPa. Period prevalence and risk factors for late presentation were evaluated.

Results: Six hundred fifty-three HCV-monoinfected and 210 HIV/HCV-coinfected patients (mean age, 48.6±12.7 y; 65.5% male) were included. Overall 32.5% of patients had advanced liver disease. In 2014 39.4% of patients presented with advanced liver disease, decreasing to 30.1%, 34.4%, and 26.4% in the years 2015, 2016, and 2017 (P=0.057), respectively. Patients with and without advanced liver disease differed in age (P<0.0001), CD4 ≤350/µL (P=0.027), genotype (P=0.005), transmission route (P=0.047), body mass index (P<0.001), and time since diagnosis (P=0.007). In the multivariable binary logistic regression analysis GT3, age above 45 years and being diagnosed >2 years ago were positively and HCV transmission through men who have sex with men was negatively associated with advanced liver disease.

Conclusions: Overall 32.5% of patients presented with advanced liver disease. We observed a trend toward a lower proportion of patients starting treatment late.GT3, age, years since HCV diagnosis and HCV transmission route were identified as risk factors for presentation with advanced liver disease.
