Correlation of polymorphisms in genes coding cytokines TNF-α, IL-10, MBL2, IFN-γ and IL-6 with complicated course of urogenital chlamydial infection in men

Abstract


Goal. To develop a personified approach to the management of men with the urogenital chlamydia infection based on studying the molecular and genetic risk factors of the development of complications. Materials and methods. Patients with the urogenital chlamydia infection (20 men with the urogenital chlamydia infection of the lower urogenital tract and 20 men with complicated forms of the urogenital chlamydia infection) and men without any clinical or laboratory signs of STDs and inflammatory diseases of the urogenital tract. The following methods were used in the study: anamnestic, clinical, instrumental (transrectal ultrasonography) and laboratory (microscopic, bacteriological, molecular and biological (PCR, SNaPshot)). Results. According to the study results, the share of cases of ureteritis caused by C. trachomatis amounted to 10.5% of the total share of cases of ureteritis and 13.0% of cases of non-gonococcal ureteritis. The percentage of complicated urogenital diseases caused by C. trachomatis amounted to 34.5% of the total share of complicated forms and 35.7% of noncomplicated forms of the non-gonococcal origin. Subjective clinical signs of complicated forms of the chlamydia infection did not have any reliable distinctions from those observed in case of non-complicated forms of the disease; the infectious process caused by C. trachomatis was characterized by the absence of leukocytosis in the urethra in 30.0% of men with both non-complicated and complicated forms of the disease. The study of the polymorphism of cytokine genes revealed that the CC genotype of IL-6 gene at the -174 locus can serve as a molecular predictor of the complicated course of urogenital chlamydiosis in men while the GC genotype of IL-6 gene at the -174 locus can serve as a molecular predictor of the non-complicated course of urogenital chlamydiosis in men. Based on these results, the authors developed an algorithm for a differential approach to the management of patients suffering from chlamydia infection. Conclusion. A differential approach to the management of men with the urogenital chlamydia infection depending on the molecular predictor of the complicated course of the disease was developed.
