SANCHEZ RODRIGUEZ, Yoan Antonio et al. Recombinant Interferon alfa-2b plus Ribavirin in treatment of chronic hepatitis C. Rev cubana med [online]. 2010, vol.49, n.2, pp. 0-0. ISSN 1561-302X.
The hepatitis C virus becomes in leading cause of chronic hepatitis, hepatic cirrhosis, hepatocarcinoma and liver transplant at world level. OBJECTIVE: The aim of present study is to determine the virological, biochemical and histological course of patients presenting with Chronic hepatitis C under a combination of recombinant Interferon alfa-2b plus Ribavirin and to identify the main factors associated with the rates obtained of virological response. METHODS: A non-controlled and multicenter phase IV clinical-therapeutical trial was sponsored by the Institute of Gastroenterology and the Genetics and Biotechnology Engineering Center from May, 2002 to May, 2006. Sample included 122 patients diagnosed with chronic hepatitis C fulfilling the predetermined inclusion and exclusion criteria. Recombinant Interferon alfa-2b (3 millions of t.i.d units) was used plus Ribavirin (1000 or 1200 mg daily depending on the body weight) during 48 weeks. RESULTS: We achieved a sustained biochemical and virological response rate of 32.8 and 50.8 %, respectively at week 72. A 41.3,% from the total of patients had a histological improvement at the expense of reduction of fibrosis and a few changes in inflammation level. CONCLUSIONS: Raking into account the global response rate achieved this combined treatment was considered effectiveness for chronic hepatitis C and we recommended to deepen in the knowledge of infection in Cuba, as well as in more efficient treatment options for this disease.
