| Popis: | Aim. To assess the predictive value of single-nucleotide polymorphisms of hemostasis and folate cycle genes in hemorrhagic fever with renal syndrome (HFRS). Methods. 43 patients undergoing HFRS were examined based on the Republican clinical infectious diseases hospital in Izhevsk. Toxic shock syndrome (TSS) in the decompensated phase, pulmonary edema in the alveolar phase, and acute kidney injury (AKI) at stage F [RIFLE criteria (risk, injury, failure, loss, end-stage renal disease)] were registered as complications. Molecular analysis of patients genomic DNA was performed after its isolation from peripheral blood cells. Genotyping was performed by using multiplex real-time PCR with conformationally restricted probes. Statistical analysis was performed by the licensed program SPSS 22.0; the significance level of difference between groups was determined using the nonparametric MannWhitney test (for quantitative variables) and the Fishers exact test (for qualitative variables). Results. The C/C genotype of the ITGB3:1565T/C gene (p=0.0278), and the C/C genotype of the MTHFR1298 A/C gene (p=0.0407) was less common in severe cases, while the G allele of FGB:455G/A gene (p=0.046) and the T allele of the ITGB3:1565T/C gene (p=0.0166) was more frequent. More frequent detection of the 5G/4G genotype of the PAI-1:675 5G/4G gene was found in the case of TSS (p=0.0433). Genotype C/C of the ITGB3:1565T/C gene (p=0.0145) and a combination of pathological genotypes A/C and C/C of the MTHFR1298A/C gene (p=0.0004) are less common in the development of AKI at stage F. Conclusion. The molecular genetic analysis makes it possible to identify patients with genotypes predisposing to a severe and complicated course of hemorrhagic fever with renal syndrome. |
