Abstract

The effects of Ukrain and recombinant human interferon-alpha 2b (IFN) on the state of the thiol-disulfide ratio (SH/SS) of the blood (Russian Federation patent no. 2150700) were studied in vitro using the amperometric titration method. The blood of 73 chronic hepatitis C (CHC) hepatitis C virus (HCV)-RNA-positive patients was examined. Ukrain was tested in doses of 0.05-2.0 micrograms/ml and IFN in 20-1000 U/ml of blood. After in vitro examination, 59 patients were treated: 28 with Ukrain and 31 with IFN. The first group of 16 patients (including eight with HCV genotype 1b) was treated with individually selected optimal doses of Ukrain (0.5-2.5 mg every second day). The second group of 12 patients was treated with doses of 2.5 mg Ukrain independent of in vitro test results. The third group of 31 patients was treated with individually selected optimal doses of IFN (0.5-2 MU 3 times a week). It was found that 79.4% of CHC patients were sensitive to Ukrain in vitro and 65.1% were sensitive to IFN. CHC patients with genotype 1b were sensitive to IFN only in 16.7% of cases while the figure for Ukrain was 92.3%. CHC patients with other HCV genotypes (3, 1a, 2) were sensitive to Ukrain in 86.7% of cases and to IFN in 70.6%. After 1 mo...Continue Reading
