The advent of highly effective and well-tolerated direct antiviral antivirals (DAAs) has dramatically changed the landscape of chronic hepatitis C. The effect of DAAs in older adults is difficult to determine since patients aged ≥ 65 years were too few in most clinical trials and data mainly come from observational studies. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of DAAs in patients aged 65 and older. PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, HCV-Trials.com databases were searched for literature published until 1 December 2017. English language articles reporting results of phase 2 or 3 randomized controlled trials (RCTs), single-arm clinical trials (SATs) and observational studies were included in the final analysis. All studies included subgroups of older patients and compared their outcomes with younger individuals. By using a random-effects or fixed-effects model, odds ratio (OR) was calculated for the efficacy and safety. Heterogeneity was tested using I2 statistics. Thirty-seven studies reported data on the DAA efficacy. The OR was 1.66 (95%CI: 1.00-2.75; P = 0.06) in meta-analysis of RCTs, and similar results were found in SATs and observational studies. HCV genotype, stage of fibrosis or HIV co-infection did not affect the rate of SVR in older persons. Prevalence of anaemia (OR 0.26 95%CI: 0.09-0.69; P = 0.007) (OR 0.25 95%CI: 0.09-0.69; P = 0.007) and skin complaints (OR 0.61 95%CI: 0.45-0.83; P = 0.001) was higher in older adults. Finally, geriatric patients affected by chronic HCV infection can be safely treated with DAAs with the same efficacy reported in younger adults.
