    • Abstract:
      The study was aimed to estimate the role and prevalence rates of genotypes, haplotypes, and alleles, located within the single-nucleotide polymorphisms (SNPs) of interleukin (IL) 1A, IL1B, and IL6 genes, in the occurrence and development of human cytomegalovirus (HCMV) infection among pregnant women. A research was conducted in 129 pregnant women, out of whom, 65 were HCMV infected and 64 were age-matched control uninfected individuals. HCMV DNA was quantitated for UL55 gene by the real-time Q PCR in the body fluids. The genotypic statuses within the SNPs were determined by nested PCR-RFLP assays and confirmed, by sequencing for randomly selected representative PCR products. A relationship between the genotypes and alleles, as well as haplotypes and multiple variants in the studied polymorphisms, and the occurrence of HCMV infection in pregnant women, was determined using a logistic regression model. TT genotype within IL1A polymorphism significantly decreased the risk of HCMV infection (OR 0.32, 95% CI 0.09-1.05; p ≤ 0.050). Considering IL6 SNP, the prevalence rate of GC genotype was significantly decreased among the HCMV infected, compared to the uninfected control individuals (OR 0.45, 95% CI 0.21-0.99; p ≤ 0.050). Moreover, CC homozygotic status in IL6 SNP, found in pregnant women, significantly decreased the risk of congenital infection with HCMV in their offsprings (OR 0.12; p ≤ 0.050). In multiple SNP analysis, TC haplotype within the IL1 polymorphisms significantly decreased the risk of the infection in pregnant women (OR 0.38 95% CI 0.15-0.96; p ≤ 0.050). In addition, TTG complex variants for all the studied polymorphisms and TG variants for IL1B and IL6 SNPs were significantly more prevalent among the infected offsprings with symptomatic congenital cytomegaly than among the asymptomatic cases (p ≤ 0.050). In conclusion, the analyzed IL1A -889 C>T, IL1B +3954 C>T, and IL6 -174 G>C polymorphisms may be associated with the occurrence and development of HCMV infection among studied patients.
