Abstract

BACKGROUND:

The natural history of hepatitis C genotype III infection, the predominant form in India, is not wholly understood. This study attempted to compare the natural history of diseases due to genotypes III and I.

METHODS:

This 10-year prospective follow-up study (mean follow-up period = 3.6 +/- 1.4, range = 1-10 years) included 108 patients of hepatitis C. Group 1 comprised 65 patients with hepatitis C genotype III infection (mean age = 46.1 +/- 11.3 years, male: female = 1.8 : 1) and group 2 comprised 43 patients with hepatitis C genotype I infection (mean age = 44.2 +/- 8.2 years, male: female = 2.1 : 1). Demographic features, clinical presentation and course, response to treatment (either interferon-ribavirin or peginterferon-ribavirin combination) and complications were noted for all patients. Data were analysed using the chi-square test and Student's t-test.

RESULTS:

The number of steatosis cases was larger in group 1 (32.3%, 21/65 patients) than in group 2 (18.6%, 8/43 patients) although statistically not significant. There was no significant difference in the mode of infection, presence of diabetes, obesity or alcoholism, clinical presentation, extra-hepatic manifestations, stage of liver disease, complications like decompensation or hepatocellular carcinoma and mortality. Overall, the sustained treatment response was significantly greater in group 1 patients [(87.5%, 21/24 treated patients vs. 56.2%, 9/16 treated patients in group 2; p = 0.0001)].

CONCLUSION:

HCV with genotype III was associated with better treatment response. Although statistically not significant, more number of patients in genotype III had steatosis.
