Abstract

OBJECTIVES:Previous studies have found ethnicity to be an important predictor of outcomes of treatment with peginterferon (PEG-IFN) and ribavirin (RBV) in chronic hepatitis C. Although the expected sustained virological response (SVR) rates of Hispanics and African Americans are lower than those of Caucasians, SVR rates in Asians appear to be more favorable. However, in some of these studies, hepatitis C virus (HCV) genotype was identified by INNO-LiPA assay, which can mistype the easier-to-treat HCV genotype 6 as genotype 1. Our goal was to compare SVR rates among Caucasian and Asian-American patients with genotype 1 and 2/3 infection whose HCV genotypes were accurately classified by core sequencing testing.METHODS:A cohort of 269 consecutive treatment-naive HCV-infected patients with genotype 1 or 2/3 (157 Caucasians and 112 Asians) treated with PEG-IFN+RBV from January 2001 to November 2007 at four community-based gastroenterology clinics in Northern California were studied. The analysis of data was by intention-to-treat.RESULTS:The SVR rates for patients with genotype 1 were 45% for Caucasians and 52% for Asians (P=0.37). The SVR rates for patients with genotype 2/3 infection was 77% for Asians and 74% for Caucasians (P=0.7). On multivariate logistic regression analyses adjusting for age, alanine aminotransferase (ALT), baseline viral load, HCV genotype, and treatment adherence, we did not find Asian ethnicity to predict SVR. On a separate analysis, we found that Asians who had HCV genotype 1 or 1b by the less accurate INNO-LiPA assay had significantly higher SVR rates than Caucasians with genotype 1 (64% vs. 45%, respectively, P=0.03).CONCLUSIONS:SVR rates were similar in Asian Americans and Caucasians infected with HCV genotype 1 or 2/3 when HCV genotype classification was accurately determined.
