Pathophysiology of hepatitis C and diabetes mellitus: Towards the cure of two epidemics in the 21st century

Abstract

Chronic hepatitis C virus (HCV) and diabetes mellitus (DM) are two public health problems that impact health care systems with overall high costs. HCV infections cause liver manifestations such as hepatitis, cirrhosis and hepatocellular carcinoma. They have also been involved in the pathogenesis of extrahepatic manifestations among which are metabolic disorders such as DM. Longitudinal and cross-sectional studies have reported a higher incidence and prevalence of DM in patients with chronic HCV infections. DM accelerates histological and clinical progression of chronic HCV infections and leads to cardiovascular complications. Recently, progress has been made in treatment with the introduction of new medications such as direct-acting antiviral drugs that improve glycemic control in these patients.
