About

To evaluate the effect of treatment of insulin resistance in the response of chronic hepatitis C treatment, mesure as HCV-RNA negative at week 72.

4.3.2 Objetivos secundarios To evaluate the efficacy and safety of treatment with metformine to erradicate the insulin resistance of patients with chornic hepatitis C genotype 1 measure as HOMA-IR < 2.

Full description

Differents studies show that infection by virus hepatitis C have a relevant rol in the development of insulin resistance. The insulin resistence is associated with a progression of fibrosis and the development of steatosis. The insulin resistence is frecuently associated with very difficult to cure patients as cirrhotics, afro-american patients, overweight patients and co-infected HCV-HIV patients. Recently is repported that sustained virological (SVR) response in genotype 1 patients is different according the insulin resistance. The SVR was 60% in patients without insulin resistance versus 20% in patients with strong insulin resistance (HOMA > 4.

The present trial desire to analyze the effect that the treatment of insulin resistance produce in higher range of RVS.
