The clinical significance of changes in genetic heterogeneity of the hypervariable region 1 in chronic hepatitis C with interferon therapy
M Shindo, K Hamada, S Koya, K Arai, Y Sokawa, T Okuno – 1 November 1996 – We examined changes in the hypervariable region 1 of the hepatitis C virus (HCV) RNA that occurred with interferon therapy in 33 patients with chronic hepatitis C to assess the clinical significance of this region. The 33 patients had HCV genotype 1b and were classified into three groups based on serum aminotransferase levels during and after therapy with α interferon; long‐term responders (n = 9), short‐term responders (n = 11), and nonresponders (n = 13).
