Human papilloma virus in the urethra in HIV-infected men in the Рrimorsk region

Abstract

Objective of the study: identification of HPV and identification of the most common types in urethral swabs taken from HIV-1- infected men, as well as determination of the dependence of the presence of HPV in patients with HIV viral load (VL) and CD4 + T-lymphocyte count.Materials and methods. The study included 34 HIV-1-infected men being monitored at the Center for the Prevention and Control of AIDS and Infectious Diseases (Vladivostok). They were asked to undergo a urological examination, including the collection of urethral swabs, as well as a face-to-face interview to collect socio-demographic, behavioral and clinical-anamnestic data.Results. HIV-1-infected patients (34 people) included in the study were 25–60 (37,8±7,1) years old. HPV was detected in 23 (67,6%) patients aged 25–45 (37,8±5,5) years. The vast majority of patients with multiple HPV infection reported having had sex with three or more sexual partners and did not always use a condom, and 17.4% of the men surveyed said they never used one. In the past, 47.8% of HPV-positive patients used narcotic substances, and 30.4% of the respondents, at the time of the survey, were active users of psychoactive substances. In 23 HIV 1-infected men, 9 genotypes were identified — 6 (HPV-HP), 16, 18, 33, 35, 52, 53, 58, 73 (HPV-VR) — belonging to 5 types of HPV: AlphaPV-6, AlphaPV-7, AlphaPV-9, AlphaPV-10, AlphaPV-11. In 5 patients, coinfection of two genotypes was revealed, in 3 — two types of HPV. The most common genotype was HPV-16 (30,4%) and HPV-18 (26,1%), the least HPV-{6, 58, 73} (1/23≈4,3%). The presented results indicate the need to create diagnostic programs focused on early detection of cancer of the anogenital region in persons of both sexes in patients with immunodeficiency states, primarily in HIV 1-positive patients with HPV-HR.
