[Effects of CCR5-delta32, CCR2-64I and SDF-1-3'A polymorphic alleles on human immunodeficiency virus 1 (HIV-1) infection in the Polish population].

Abstract

Among many factors that can influence vulnerability to infection and disease progression are genetic host factors together with the phenotype/genotype of the transmitting virus and the route of infection. Each of these factors alone or in combination could determine susceptibility to infection and subsequent rate of progression towards AIDS. Between host genetic factors identified and analyzed for their role in HIV-1 transmission and disease progression are polymorphisms in the genes encoding chemokine receptors and CCR5, CCR2 and SDF-1 a natural ligand for CXCR4 receptor. It has been shown that the distribution of this genetic polymorphisms and their role in the course of disease varies between different racial, ethnic and risk groups. The aim of present study was to examine the frequencies of polymorphic alleles CCR5-delta32, CCR2-64I and SDF-1-3'A and their role in human immunodeficiency virus (HIV-1) transmission in Polish population. The allelic and genotype distribution was studied in 103 HIV-1 infected patients (group HIV+) and 59 seronegative participants (group HIV-). Genotyping was done by the use of polymerase chain reaction with sequence-specific primers and restriction fragment length polymorphism. We found higher prevalence of CCR5-delta32 mutant allele among seronegative participants (13.6%) compared with HIV-infected patients (9.7%), although this did not attain statistical significance (p = 0.29). The CCR2-64I allelic frequency was almost identical in the HIV- and HIV+ groups (12.7% vs. 12.6%; respectively; p = 0.98). In contrast, the SDF-1-3'A allelic frequency was slightly lower among seronegative participants (15.3%) compared with HIV-infected patients (16.5%), and observed difference was not statistically significant (p = 0.77). Furthermore, we found that the genotype or allelic frequencies among HIV-1 infected patients were independent on the participant's sex, age at HIV-1 infection and the transmission route. Our results showed no significant differences in the prevalence of examined alleles and genotypes between HIV-1 infected patients and seronegative participants, which indicates that in the examined population they are not influencing host susceptibility to the HIV-1 infection.
