Abstract

Background/aim In the era of direct-acting antiviral medications, which can cure the hepatitis C virus (HCV) infection, the actual epidemiology of this condition in the general population is still unclear. We therefore aimed to estimate the prevalence rate of HCV and assess the determinants for incident cases of HCV in primary care in Italy. Methods We identified outpatients aged at least 15 years registered in the Italian Health Search IMS Health Longitudinal Patient Database from 1 January 2002 to 30 June 2013. The annual trend of HCV prevalence was estimated. The candidate determinants for the risk of incident HCV infection included geographical area of residence, sex, age, infections by the HIV, hepatitis B virus (HBV), or other forms of hepatitis, and abuse of illicit substances or drugs. Results The eligible cohort included 826 300 patients (53.5% women, mean age 48.1 ± 19.1 years). The prevalence rate of HCV increased over the 11-year study period, ranging from 0.24 to 0.50%, with a small increase in men versus women. Patients aged more than 24 years had a higher risk than those aged 14–24 years, with up to a five-fold increase among patients aged 65–74 years. Being resident of Southern/Islands Italy, concurrent diagnosis HBV or HIV, and drug or illicit substance abuse were significant determinants for HCV infection. Conclusion Our study shows that the prevalence of HCV in Italy has doubled over the last decade. Patients with certain demographics and clinical characteristics are more prone to be infected by HCV. In this scenario, general practitioners may play a crucial role in screening, early identification, and therapy of high-risk patients.
