RESUMEN
BACKGROUND AND AIMS: Direct acting antiviral agents (DAAs) have revolutionized the landscape of chronic hepatitis C (CHC) enabling treatment of all those infected. It remains to be determined how the characteristics of those receiving treatment are changing. MATERIALS AND METHODS: We retrospectively analysed all the patients with CHC who received treatment with DAAs in a large referral centre since 01/01/2015. We stratified their demographic, clinical and virological characteristics at baseline and the sustained virological response (SVR) rates according to the year of treatment. RESULTS: In the study were included 2565 patients. During the study period, the yearly proportion of men and cirrhotic patients decreased (p<0.001) whereas mean age increased from 59.8 to 62.2 years old (p=0.04). An increasing trend was observed in the foreign-born patients from 4.3% to 7.9%, without reaching statistical significance. The prevalence of comorbidities had also increased during the study period (p<0.001). Instead, the yearly number of experienced patients decreased significantly (p<0.001) as well as the mean MELD score of cirrhotic patients from 9 to 7.6 (p<0.001). SVR rates increased significantly, from 93.4% in 2015 to 97.1% in 2018 (P<0.05). CONCLUSIONS: The population of patients with CHC receiving DAAs is becoming older and with more comorbidities. Nevertheless, this did not impact SVR rates.
