<i>KIR2DS3</i> gene frequency is increased in co-infected patients that fail to achieve SVR.

KIR2DS3 was genotyped in our cohort by PCR-SSP. The carrier frequency of KIR2DS3 in 149 HCV/HIV-1 co-infected treated with peg-IFN and ribavirin was compared in 101 patients who achieved SVR following treatment and 48 patients who did not achieve SVR. Differences in frequency populations were tested for significance by χ2 test. Odds ratio with 95% confidence intervals is shown.
