Evaluation of the global HIV burden in Russia, identification of progress made and outstanding problems for 1987–2021.Materials and methods. The analysis of national and foreign publications, data obtained from Rosstat, from forms of federal statistical observation and the FNM of the AIDS Center of Rospotrebnadzor was carried out. The study used information-analytical, epidemiological and statistical methods. Mathematical calculations were performed using the SPSS-26 program.Results and discussion. In Russia, the target indicators of the state program of HIV/AIDS response strategy is being provided in different directions: the greatest success has been achieved in conducting chemoprevention of mother to child HIV transmission, somewhat less in the coverage of the population with HIV testing, which amounted to 26.1% versus the target indicator of 30.0% in 2021, the number of newly detected cases of HIV infection is decreasing (from 73.7 to 71.0 thousand people in 2020–2021, versus the target indicators of 76.1 and 72.3 thousand people, respectively), there is decreasing the HIV incidence (40.4 per 100 thousand. in 2021 versus 68.5 in 2015). Antiretroviral therapy (ART) coverage of patients registered in AIDS Centers went up from 12.4% to 78.9% in 2007–2021. Meanwhile, the determining factor in the HIV/AIDS epidemic progress in Russia is a heterosexual route (F=75.1, p<0.0001) leading to the penetration of infection into all population segments. In addition, despite the increase in the coverage of ART for people living with HIV (PLWH), the HIV mortality rate is remaining high (11.6 per 100 thousand population in 2021, versus 7.9 in 2007).Conclusion. In recent years, there has been a positive trend in the coverage of three-stage HIV chemoprophylaxis in pregnant women, women in labor and newborns. The number of HIV population based screening tests is increasing annually. There is an increase in the ART coverage of patients and a decrease in the number of newly diagnosed cases of the disease. However, along with the observed increase in the HIV spread through heterosexual contacts, it is necessary to strengthen information and preventive measures, especially among the reproductive age group. The high HIV mortality rate is continuing to remain, despite the increase in ART coverage of PLWH. The identified problems need to be solved comprehensively based on the results of large-scale sociological research conducted in various regions of Russia.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42978717","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}

The majority (92%) of young adults living with HIV since birth or childhood retained in the health care system in the first year after the transition, but only 53–62% were highly adherent to treatment and monitoring for HIV infection in the first years after the transition. Episodes of non-adherence to treatment during childhood and adolescence, «more complex» ART scheme and the lack of adult’s social support at the time of 18th birthday increase the likelihood of interruption in treatment adherence in the first year after transition to adult care, while the combination of these factors has negative consequences for adherence and continuity of treatment for a longer period of time.Conclusion.

In the beginning of 2000s infectious mortality in Russian regions was predominantly determined by socially significant diseases i.e. TB, hepatitis and HIV. Over 20-year period contribution of HIV to mortality within the class «Certain infectious and parasitic diseases» increased multi-fold and it moved to the top of ranking. According to experts’ opinion, accelerated increase of mortality from HIV in the second decade of XXI century was partly conditioned by peculiarities of registration of death causes as well as insufficient antiretroviral coverage in Russian regions.Objective. Identification of trends and features of the dynamics of mortality from HIV/AIDS in certain age groups in the subjects of the Russian Federation.Materials and methods. Analysis of mortality indicators in Russian regions was conducted using official statistics of Rosstat and Federal Service for Surveillance in Healthcare for 2000–2021. Method of direct ranking was applied to analyze mortality from HIV-associated causes.Results and discussion. According to official statistics, mortality from HIV-associated causes has reached its peak values in 2018. Analysis of gender differences shows that mortality in males is twice higher than in females. There are substantial differences in regional levels of mortality from HIV-associated causes. The highest mortality levels from those causes were registered in several regions of Siberia and Urals.Conclusion. The study results show that Kemerovo region is the most unfavourable in terms of HIV-mortality. In 2021, the indicator estimated 50.4 per 100,000 that is nearly 5-fold higher than the country’s average. The number of HIV deaths in Kemerovo region was higher than cumulative number of deaths from external causes (alcohol poisonings, suicides, homicides, drownings and transport injuries). High levels of mortality from HIV were also registered in Perm territory (32.3), Irkutsk (32.2), Novosibirsk (27.5) and Sverdlovsk (26.4) regions.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68331222","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}

Rosstat data for 2002–2021 were used to analyze mortality from tuberculosis, HIV infection, infectious diseases and COVID-19 in Russia. Information on the number and causes of death of contingents with tuberculosis and HIV infection was obtained from Federal statistical observation Forms No. 61, No. 8 and No. 33 for 2012–2021. Information on the causes of death of contingents with tuberculosis, including from COVID-19, was received upon request from 16 subjects of the Russian Federation. Statistical analysis was carried out using the program Stat Tech v.2.8.8 (developed by Stattech LLC, Russia).Results and discussion. In Russia, during the pandemic (2020–2021), there was a synchronous decrease in mortality from infectious diseases, tuberculosis and HIV infection. At the same time, a «reverse transition» was registered in the dynamics of these indicators, as a result of which the rates of reduction in mortality from HIV infection exceeded those from tuberculosis for the first time in the last 20 years.The main factor that had a positive impact on the dynamics of mortality from HIV infection was an increase in the coverage of HIV-infected patients with antiretroviral therapy, the share of which increased to 82.2% and 83.3% in 2020–2021 (2019 — 71%). The deterioration of the epidemic situation of tuberculosis during the pandemic was due to the introduction of restrictive measures (lockdown), which led to a decrease in the proportion of the population covered by screening aimed at early detection of tuberculosis among the population. As a result, in the structure of the deceased contingents with tuberculosis, the proportion of those whose cause of death was tuberculosis increased to 30% (ICD-10 A15–A19).Such dynamics was due to an increase to 7.6% in the proportion of patients diagnosed with tuberculosis posthumously (in 2019 — 4.8%). In addition, among the deceased contingents with tuberculosis, every 3rd was a patient with tuberculosis combined with HIV infection. During the pandemic, in 16 regions of the Russian Federation, the proportion of deaths from COVID-19 was low and amounted to only 2.3% in the structure of deceased contingents with tuberculosis.Conclusion. During the pandemic (2020–2021) in Russia, there was a slowdown in the rate of decline in mortality from tuberculosis, due to an increase in the proportion of patients in whom tuberculosis was detected late as a result of post-mortem diagnosis. Maintaining a high proportion of patients with tuberculosis combined with HIV infection in the structure of deceased populations with tuberculosis slows down the rate of reduction in mortality from HIV infection.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44646796","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}

In Vietnam, there has been an increase in efforts to monitor and prevent mother-to-child transmission of HIV since 2013. However, data on HIV drug resistance among HIV-1 infected children younger than 18 months of age remain limited. The study fills a critical knowledge gap by providing important insights into the prevalence of resistance among this population in the Southern and Central Highland provinces of Vietnam.Objective. This study aimed to determine the prevalence of HIV drug resistance and patterns of mutation among treatment-naïve children under the age of 18 months who had been recently diagnosed with HIV.Material and methods. Between May 2017 and May 2021, stored remnant DBS samples were collected from children under the age of 18 months who had been diagnosed with HIV through routine Early Infant Diagnosis testing in Central Highland and Southern Vietnam. HIV drug resistance tests were performed, and interpretation was done using the Stanford algorithm.Results and discussion. Overall, 111 samples with eligible viremia for sequencing (ct value <31) were collected for genotyping, in which 110 protease sequences and 106 complete reverse transcriptase regions were generated. Males were 61.3%, 52.3% were aged from 6 weeks to <9 months and 37.0% were breastfed. Access to mother-to-child intervention was reported in 60.3%. The accumulation of major drug resistance mutations was found in 43.8% of infants and most of them were resistant to Non-nucleoside Reverse Transcriptase Inhibitors (NNRTI) (37.7%). High-level resistance to Nevirapine was present in 40% of cases. The risk factors associated with NNRTI resistance were antiretroviral prophylaxis (aOR: 3.68, 95% CI: 1.83–7.45) and breast-feeding history (aOR: 2.16, 95% CI: 1.03–4.53). CRF01-AE was the predominant subtype.Conclusion. The study identified a high prevalence of resistance to NNRTIs among HIV-1 infected infants less than 18 months of age in the Southern and Central Highland provinces of Vietnam. This highlights the need for further investigation and a potentially larger national survey to confirm the extent of this issue in Vietnam. Our findings support the current actions of the Vietnam Ministry of Health, which prioritize integrase inhibitor-based regimens as the preferred first line of ART for children to achieve durable viral suppression and minimize treatment failure.

The material for the study was blood plasma samples of 972 pregnant women from the Republic of Guinea. The patients were examined for the presence of HIV infection serological (Ag+Ab) and molecular markers (RNA). For patients with a positive PCR result and a sufficient viral load (>500 c/ml), the genetic sequences of the pol gene fragment responsible for the synthesis of pro and rev proteins were obtained by Sanger sequencing. These sequences were used for phylogenetic analysis and examined for drug resistance mutations.Results and discussion. 12.96% of patients was positive in ELISA. Among women who were positive in ELISA, RNA was detected in 76.98% of cases, however, in 11 cases, RNA was detected in patients without serological markers of HIV infection, so the incidence of HIV RNA in the entire surveyed population was 11.11%. In the vast majority of cases, the circulating recombinant form 02_AG is found. Based on the analysis, we assume a significant contribution of recombinant forms of HIV to the genetic diversity of the virus in the region under study.The incidence of DR mutations was quite high (26.80%). The most frequent substitutions were in position 20 of the protease (70.10%, 95% CI 59.96–78.98%), of which the K20I mutation was dominant. In addition, the L10I/V mutation was relatively common, increasing the replication of viruses with other PI resistance mutations. Among the mutations associated with HIV resistance to NNRTIs, a non-polymorphic mutation V179T was found.Conclusion. An important factor influencing the effectiveness of Prevention of Mother to Child Transmission identified in this study was the high prevalence of PDR among pregnant women in Guinea. The high prevalence of drug resistance mutations found in this study in pregnant women, as well as in ART-naive women, indicates that current regimens in Guinea are insufficient to prevent vertical HIV infection.","PeriodicalId":37381,"journal":{"name":"HIV Infection and Immunosuppressive Disorders","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44520168","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}
