Resumo

Objective. To identify single nucleotide polymorphism (SNP) at the rs8099917 and rs12979860 loci of the interleukin 28B (IL-28B) gene in patients with mixed chronic hepatitis C/HIV (CHC/HIV) infection and to estimate its value in the rate of virologic response to combination antiviral therapy with Peg-IFN-a-2a and ribavirin. Subjects and methods. An AmpliSens® Genoscreen-IL28В-FL kit was used to identify SNP at the rs8099917 and rs12979860 loci of the interleukin 28B (IL-28B) gene in 43 patients (67% were males) aged 32.91±0.58 years with the duration of HCV and HIV infection being less than 10 years and 6.89±0.53 years, respectively. Results. There were rather common favorable IL-28B genotypes CCand TTand their combination, in HCVgenotype 3 in particular; the samepatients werefound to have a morepronounced inflammatory process with a high HCVRNA load. Conclusion. The identification of IL-28B SNP (rs12979860 and rs8099917) in HIV infected individuals is of practical importance in achieving virologic responses to antiviral therapy for CHC. A sustained virologic response was achieved in 80.95% of the patients with favorable genotypes CC and TT.
