It remains difficult to achieve high sustained response rates (SVRs) in chronic hepatitis patients coinfected with human immunodeficiency virus (HIV). The aim of this study was to perform a meta-analysis of randomized controlled trials (RCTs) comparing peginterferon with interferon in the treatment of patients carrying different genotypes of hepatitis C virus (HCV) and coinfected with HIV. A Medline literature search was conducted to identify RCTs evaluating SVRs to peginterferon and interferon in HCV/HIV-coinfected patients. Six studies matched the selection criteria, and the HCV genotype of 1,717 coinfected patients was reported. For genotypes 1 or 4 HCV and HIV-coinfected patients, both types of peginterferon, α-2a and α-2b, achieved higher SVRs compared with the respective types of interferon. The SVRs achieved in patients infected with HCV genotypes 1 or 4 treated with peginterferon and ribavirin was not satisfactory in comparison with those of patients infected with HCV genotypes 2 or 3 (26% vs. 55%). The probability of achieving higher SVRs in patients when treated with peginterferon plus ribavirin increased compared with other therapies, especially for patients coinfected with HCV genotypes 1 or 4 and HIV. The likelihoods of serious adverse effects and withdrawal rates were similar.
