Background: Micro-elimination of the hepatitis C virus (HCV) includes treatment in populations at risk of ongoing HCV transmission, such as men who have sex with men (MSM) or people who inject drugs (PWID). We analyzed the HCV reinfection incidence rates of participants in the German hepatitis C cohort (GECCO) and compared our data to previous findings from the interferon era., Methods: Patients with HCV reinfections in the multi-centric GECCO cohort were compared to patients in whom no reinfection occurred. The HCV reinfection incidence rate in MSM was also compared to the incidence rate in the interferon era (using data from the European Acquired Immunodeficiency Syndrome Treatment Network [NEAT])., Results: Between January 2014 and April 2018, 48 HCV reinfections occurred in 2298 individuals (2%), with 2346 cured HCV episodes. The median time to reinfection was 500 days (range 16-1160) and the overall HCV reinfection incidence rate was 1.89 per 100 person-years (py; 95% confidence interval [CI], 1.41-2.48). In a multivariate analysis, the transmission risk in MSM was the only independent risk factor of HCV reinfection (odds ratio, 39.3; 95% CI, 4.57-334.40; P = .001). The incidence rate in MSM was 9.02 (95% CI, 6.48-12.26) per 100 py, compared to 1.14 per 100 py in PWID (95% CI, .56-2.09). The incidence rate for a first HCV reinfection in MSM was similar in the direct-acting antiviral era, compared to the interferon era, with a hazard ratio of 1.05 (95% CI, .64-1.74; P = .831)., Conclusions: HCV reinfection remains a frequent finding among MSM in Germany. In addition to behavioral interventions, early HCV treatment and retreatment should be implemented for this subgroup to prevent HCV transmission., (© The Author(s) 2019.

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.

Background: Shortening the duration of treatment with HCV direct-acting antivirals (DAAs) leads to substantial cost reductions. According to the label, sofosbuvir and ledipasvir can be prescribed for 8 weeks (SL8) in noncirrhotic women or men with HCV genotype 1 and low viral loads. However, real-world data about the efficacy and safety of SL8 are largely missing., Methods: Interim results from an ongoing prospective, multicenter cohort of 9 treatment centers in Germany (GECCO). All patients started on treatment with HCV DAAs since January 2014 were included. This report describes safety and efficacy outcomes in 210 patients with HCV monoinfection and 35 with human immunodeficiency virus (HIV)-HCV coinfection given SL8 in a real-world setting., Results: Of 1353 patients included into the GECCO cohort until December 2015, a total of 1287 had complete data sets for this analysis; 337 (26.2%) fulfilled the criteria for SL8 according to the package insert, but only 193 (57.2%) were eventually treated for 8 weeks. Another 52 patients did not fulfill the criteria but were treated for 8 weeks. SL8 was generally well tolerated. The overall sustained virologic response rate 12 weeks after the end of treatment was 93.5% (186 of 199). The on-treatment response rate was 99.4% (159 of 160) in HCV-monoinfected and 96.4% (27 of 28) in HIV-HCV-coinfected patients. Ten patients were lost to follow-up., Conclusions: SL8 seems highly effective and safe in well-selected HCV-monoinfected and HIV-HCV-coinfected patients in a real-world setting., (© The Author 2016.
