A second potential benefit of achieving SVR is reduction in the rate of diabetes. Diabetes has been demonstrated to be more common in those infected with Hepatitis C than in the general population - this observation was made by examination of the NHANES population based database. The prelude to the development of Type 2 diabetes is insulin resistance. Insulin resistance (IR) is present in about one third of patients chronically infected with HCV - the rate being highest in those with cirrhosis and in those who are overweight or obese. Early data indicates that although the presence of insulin resistance impairs interferon responsiveness if SVR can be achieved, insulin resistance is lost. Studies of IR in individuals infected with genotype 3 HCV are lacking. Independent of HCV infection, being born South Asian is a risk factor for Type 2 diabetes.
