The MSM group shows a disproportionately high prevalence rate of HIV infection, with cases of syphilis/HIV co-infection also on the rise in this population. The increase in these co-infection cases deserves special attention. According to the literature, the rate of HIV infection among syphilis patients averages 15.7%. In addition, it varies significantly, going from 3% in the general population to 90% among MSM. Epidemiological surveillance data showed an increase in cases of HIV/syphilis co-infection in the MSM group, with the proportion of co-infection patients varying from 30 to 60% depending on the region. This syndemia can be explained by the fact that syphilis can contribute to HIV transmission and acquisition. The risk of HIV infection is 2 to 5 times higher among people with syphilis. At the same time, STDs are more and more difficult to control as the Internet and dating applications have made it easier to find potential sex partners. Given the high prevalence rate of syphilis among MSM, screening, diagnosis and treatment of STDs in this population should be a health care priority. Early detection and timely treatment of these socially significant diseases play an important role in epidemic prevention measures.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contributes to the appearance of drug resistance and to the formation of various HIV variants. In the world, the different variants of HIV-1 are distributed unevenly. In Russia there are circulating unique virus variants which are characteristic for our country and some countries of the former USSR and which are difference from HIV-1 variants circulating in other countries of the world. For many years, the studies aimed on the analysis of the influence of various HIV-1 variants on pathogenesis have been conducted. Within the framework of these studies, the polymorphism mutations in different subtypes and recombinant forms have been detected. Currently the main objects of antiretroviral therapy are HIV-1 structural proteins, mainly enzyme proteins, thus polymorphic mutations in which could affect the degree of virus sensitivity to antiretroviral therapy. Non-structural HIV-1 proteins are involved in virus replication and virus protection from the host immune system, enter the bloodstream and tissues, causing the development of inflammation. The polymorphic mutations in non-structural proteins could affect the degree of HIV infection progression and the development of concomitant somatic diseases. Today, nonstructural proteins are considered as objects for the creation of therapeutic agents, thus the identification of polymorphic mutations in nonstructural proteins in different HIV-1 variants is a basis for such developments. Thus, the study of polymorphism of both structural and non-structural HIV-1 proteins is a promising area of research in the future.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the general patterns and distinctive features of the formation of the HIV epidemic in chronology in various administrative territories of the Vologda Region. Materials and methods. The data of the epidemiological survey maps of HIV infection foci, reports «Causes of mortality of HIV-infected», statistical observations were analyzed: form No. 61 «Information on the contingent of HIV-infected patients», form No. 4 of the Federal State Statistical Observation, forms of the Vologda Regional Center for the Prevention and Control of AIDS and Infectious Diseases, materials of the North-Western District Center for the Prevention and Control of AIDS. Dynamic monitoring of the HIV epidemic in the Vologda Region (since 1995) and evaluation of the effectiveness of the national project to combat HIV infections were carried out. Results and discussion . On the territory of the Vologda Region, the trend of stability of the indicator of HIV infection remains. The prevalence of the population is increasing, accompanied by the identification of patients at late stages with the manifestation of secondary diseases. In the region, the HIV epidemic corresponds to the main trends of the epidemic process in the North-Western Federal District (NWFD) with some differences. The dominant transmission routes are parenteral (39.9% in 2021) and heterosexual. Over the past 5 years, there has been an upward trend in homosexual transmission of infection among men who have sex with a men (MSM), the share of which increased in 2021 by 2 times compared to 2017 and amounted to 3.1%. The detection rate in 2021, calculated for 100 thousand surveyed, in the Vologda Region was 111.3 (in the NWFD — 160.1). The highest detection rate of HIV infection was observed among MSM — 14.3% (in the NWFD — 4.1%), among injecting drug users (IDUs) — 1.0% (in the NWFD — 1.1%), among persons in prison — 1.8% (in the NWFD — 1.8%). One of the main causes of death in HIV-infected patients is the late detection of the disease and the initiation of antiretroviral therapy (ART). During the entire period of observation, the epidemic was most intense in Cherepovets and Vologda, since 2000 there has been a gradual spread of infection with involvement in the process in rural areas. Conclusion . The results obtained demonstrate the importance of implementing different models of the main stages of diagnosis, prevention and treatment of people in urban and rural areas, which is included in the developing concept of personalized HIV medicine. It is necessary to carry out additional measures for the active identification and registration of dispensary patients, the formation of adherence to dispensary monitoring and therapy, the timely appointment of ART, the introduction of new approaches to providing medical care to HIV-infected patients in the districts of the region.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the effectiveness of measures aimed at timely diagnosis of HIV infection in Russia and the subjects of the Russian Federation for the period from 2016 to 2022. Materials and methods . Information from Rosstat forms No. 4 and No. 61 for 2016–2022 and data on the population of Russia. To search for correlations between the indicators characterizing the number of persons covered by the survey and the number of identified patients with HIV infection, data from 85 subjects of Russia for 2016–2021 were used. Statistical analysis was carried out using the Statistica 10.0 program. To work with data from 85 subjects of Russia for the period from 2016 to 2021, the Jupiter Notebook interactive computing environment (6.5.2) was used. The Pandas software library (1.5.3) was used for data processing and analysis, compilation and work with a structured dataset. The statistical function module Scipy (1.9.3) was used to find correlation coefficients by the Pearson, Spearman and t-Kendall method. Scikit-learn (1.0.2) and Statsmodels (0.13.5) software libraries were used to build a trend line and find linear regression coefficients. Results and discussion . In Russia in 2016–2022, there was an annual increase in the proportion of the population covered by a survey aimed at timely diagnosis of HIV infection among the population. However, this did not lead to an increase in the number of identified patients with HIV infection, the proportion of which decreased and in 2022 reached 0.11% among the total number of examined persons (in 2016 — 0.23%). The current situation was caused by a decrease in the incidence of HIV infection in 2017–2022 by 1.5 times — from 52.8 to 34.7 per 100,000 population. As a result, in order to identify one patient with HIV infection, an increasing number of healthy individuals had to be examined, which led to an increase in the economic costs for diagnosing HIV infection in one patient. Among the examined persons there was an extremely low proportion of persons from key risk groups, which averaged 2.3% in 2018–2022, and the proportion of identified patients among them in 2022, on the contrary, reached 24.1% of their total number. As a result, it became necessary to make changes to the existing strategy aimed at expanding the coverage of the Russian population with a survey for the diagnosis of HIV infection. The results of the study showed that the increase in the coverage of the population by the survey was justified only in those 15 subjects of the Russian Federation in which coverage was low and did not correspond to the growth rate of the number of identified patients with HIV infection, which increased the risk of late detection of patients with HIV infection, when they independently applied to medical organizations with clinical manifestations of the disease.
