Abstract
The distribution of human immunodeficiency virus-1 (HIV-1) subtypes indicates difference from region to region and in risk groups acquiring the disease worldwide. Although subtype C is more in terms of total cases, subtype B is dominant in certain regions, especially in western and central Europe. Molecular epidemiological studies are essential for the control, effective treatment, and understanding in transmission routes of HIV-1 infection. This study aims to determine the molecular epidemiology and antiretroviral drug resistance profiles of HIV-1 in northern Cyprus. The study involved 71 naive HIV-positive patients diagnosed in northern Cyprus between 2016 and 2022. HIV-1 subtypes and circulating recombinant forms (CRFs) were identified by phylogenetic analysis (neighbor-joining method) of pol gene sequences. Drug resistance mutations were analyzed using the World Health Organization (WHO) lists of mutations for surveillance. The Stanford University HIVdb program was used to interpret drug resistance mutations. In our study, 40 of 71 samples were successfully sequenced. Subtype B of HIV-1 was dominant with a rate of 52.5%, followed by CRF02_AG (20%) and G (7.5%) subtypes. The rate of subtype B (71.4%) in northern Cyprus was significantly higher than in the other country of origin (p = .028). Antiretroviral drug resistance was found in 15% of the sequenced serum samples. Nucleoside/nucleotide reverse transcriptase inhibitor (NRTI), non-nucleoside nucleotide reverse transcriptase inhibitor (NNRTI), and protease inhibitor (PI) resistance rates were 10% (4/40), 7.5% (3/40), and 2.5% (1/40), respectively. According to the results, it is noteworthy that the dominant subtype circulating in northern Cyprus is the B subtype, and CRFs were detected at a higher rate than expected.

Abstract
INTRODUCTION The human immunodeficiency virus (HIV) protein p24 plays an important role in the life cycle of the virus, and also is a target for diagnostic tests and for new antiretroviral drugs and therapeutic vaccines. The most studied variant of HIV-1 in the world is subtype B. In Russia, the most common variant is A6, the spread of recombinant forms (CRF63_02A6, CRF03_A6B) is observed as well as circulation of G and CRF02_AG variants. However, a detailed study of the p24 protein in these variants has not yet been conducted. The aim was to study the features of the p24 protein in HIV-1 variants circulating in Russia and estimate the frequency of occurrence of pre-existing mutations associated with resistance to lenacapavir, the first antiretroviral drug in the class of capsid inhibitors. MATERIALS AND METHODS The objects of the study were the nucleotide sequences obtained from the Los Alamos international database and clinical samples from HIV infected patients. RESULTS AND DISCUSSION The features of HIV-1 variants circulating in Russia have been determined. V86A, H87Q, I91F are characteristic substitutions in A6 genome. It is shown that the presence of preexisting mutations associated with resistance to lenacapavir is unlikely. CONCLUSION Features of the p24 protein in HIV-1 variants circulating in Russia allow them to be distinguished from others variants and among themselves. The prognosis for the use of lenacapavir in Russia is generally favorable. The results obtained could be taken into account in developing and using antiretroviral drugs and therapeutic vaccines.

Abstract
The HIV/AIDS epidemic in Russia is growing, with approximately 100,000 people infected annually. Molecular epidemiology can provide insight into the structure and dynamics of the epidemic. However, its applicability in Russia is limited by the weakness of genetic surveillance, as viral genetic data are only available for <1 per cent of cases. Here, we provide a detailed description of the HIV-1 epidemic for one geographic region of Russia, Oryol Oblast, by collecting and sequencing viral samples from about a third of its known HIV-positive population (768 out of 2,157 patients). We identify multiple introductions of HIV-1 into Oryol Oblast, resulting in eighty-two transmission lineages that together comprise 66 per cent of the samples. Most introductions are of subtype A (315/332), the predominant HIV-1 subtype in Russia, followed by CRF63 and subtype B. Bayesian analysis estimates the effective reproduction number Re for subtype A at 2.8 [1.7–4.4], in line with a growing epidemic. The frequency of CRF63 has been growing more rapidly, with the median Re of 11.8 [4.6–28.7], in agreement with recent reports of this variant rising in frequency in some regions of Russia. In contrast to the patterns described previously in European and North American countries, we see no overrepresentation of males in transmission lineages; meanwhile, injecting drug users are overrepresented in transmission lineages. This likely reflects the structure of the HIV-1 epidemic in Russia dominated by heterosexual and, to a smaller extent, people who inject drugs transmission. Samples attributed to men who have sex with men (MSM) transmission are associated with subtype B and are less prevalent than expected from the male-to-female ratio for this subtype, suggesting underreporting of the MSM transmission route. Together, our results provide a high-resolution description of the HIV-1 epidemic in Oryol Oblast, Russia, characterized by frequent interregional transmission, rapid growth of the epidemic, and rapid displacement of subtype A with the recombinant CRF63 variant.

Abstract
The analysis of a pol gene fragment encoding protease and part of reverse transcriptase was carried out for 55 sera collected in 2016 and 2018 from HIV-1-infected patients diagnosed in 2014-2018 living in the south of Western Siberia, Russia: Altai Territory (n = 11), Republic of Altai (n = 15), Kemerovo region (n = 18), and Novosibirsk region (n = 11). CRF63_02A was the dominant genetic form (>70%) in the Altai Territory and Kemerovo and Novosibirsk regions, with subsubtype A6 comprising <30% of samples. In the Altai Republic, subsubtype A6 was predominant (53%), with 33% of viruses belonging to CRF63_02A. Four CRF63_02A/A6 unique recombinant forms were identified in the Altai Territory, Kemerovo Region, and the Altai Republic. A majority (11 of 15) of CRF63_02A viruses from Kemerovo were grouped in a cluster. Antiretroviral (ARV) drug resistance mutations were found in 6 (14%) of 43 drug-naive patients. This study provides new insights in HIV-1 molecular epidemiology and prevalence of transmitted ARV drug resistance mutations in Southwestern Siberia.

Abstract
INTRODUCTION HIV-1 subtypes have been associated with less favourable clinical profiles, differences in disease progression and higher risk of neurocognitive deficit. In this study we aimed to analyse the long term survival disparities between patients infected with the most common HIV-1 variants observed in Poland. METHODS For the study data from 518 Caucasian non-immigrant patients of Polish origin infected with divergent HIV subtypes and variants [subtype A (n = 35, 6.8%), subtype B (n = 386, 74.5%), subtype C (n = 13, 2.5%), subtype D (n = 58, 11.19%) or other non-A,B,C,D (n = 26, 5.01%)variants] were analysed. Subtyping was performed using the partial pol (reverse transcriptase and protease) sequencing. HIV variant was coupled with clinical, virologic and survival data censored at 20 years of observation. Overall survival and on antiretroviral treatment survival was analysed using Kaplan-Meyer as well as unadjusted and multivariate Cox proportional hazards models. RESULTS Significantly higher mortality was observed among subtype D (28.8%) infected subjects compared to subtype B (11.7%, p = 0.0004). Increased risk of death among subtype D cases remained significant when cART treated individuals were analysed, with on-treatment mortality of 26.9% for subtype D (p = 0.006) compared to 10.73% in subtype B infected cases. Kaplan-Meyer survival estimates differed significantly across all investigated HIV-1 variant groups when overall 20 year mortality was analysed (log rank p = 0.029), being non-significant for the cART treated group. In multivariate model of overall 20 year survival, adjusted for age at diagnosis, gender, HCV and AIDS status, lymphocyte CD4 count, transmission route and HIV viral load, only age and subtype D were independently associated with higher likelihood of death [HR: 1.08 (95%CI: 1.03-1.14, p = 0.002) and HR: 7.91 (95%CI:2.33-26.86), p < 0.001, respectively]. In the on-treatment (cART) multivariate model of 20 year survival adjusted for the same parameters only subtype D remained as the independent factor associated with higher mortality risk [HR: 4.24 (95%CI:1.31-13.7), p = 0.02]. CONCLUSIONS Subtype D has an independent deleterious effect of survival, even in the setting of antiretroviral treatment. Observed effect indicated higher clinical vigilance for patients infected with this subtype even after long time of stable antiretroviral treatment.

Abstract
BACKGROUND HIV infection is a major health problem in Russia. We aimed to assess HIV prevalence in different population groups and to compare the characteristics of 4th generation immunoassays from Abbott, Bio-Rad, Vector-Best, Diagnostic Systems, and Medical Biological Unit. METHODS The study included 4452 individuals from the general population (GP), 391 subjects at high risk of HIV infection (HR) and 699 with potentially interfering conditions. HIV positivity was confirmed by immunoblot and by HIV RNA, seroconversion and virus diversity panels were also used. HIV avidity was employed to assess recent infections. RESULTS The prevalence in GP was 0.40%, higher in males (0.62%) and in people aged < 40 years (0.58%). Patients attending dermo-venereal centers and drug users had a high prevalence (34.1 and 58.8%). Recent infections were diagnosed in 20% of GP and in 4.2% of HR. Assay sensitivity was 100% except for one false negative (99,54%, MBU). Specificity was 99.58-99.89% overall, but as low as 93.26% on HR (Vector-Best). Small differences on early seroconversion were recorded. Only the Abbott assay detected all samples on the viral diversity panel. CONCLUSION HIV infection rate in the high-risk groups suggests that awareness and screening campaigns should be enhanced. Fourth generation assays are adequate but performance differences must be considered.

Abstract
Russia has one of the largest and fastest growing HIV epidemics. However, epidemiological data are scarce. Sub-subtype A6 is most prevalent in Russia but its identification is challenging. We analysed protease/reverse transcriptase-, integrase-sequences, and epidemiological data from 303 patients to develop a methodology for the systematisation of A6 identification and to describe the HIV epidemiology in the Russian Southern Federal District. Drug consumption (32.0%) and heterosexual contact (27.1%) were the major reported transmission risks. This study successfully established the settings for systematic identification of A6 samples. Low frequency of subtype B (3.3%) and large prevalence of sub-subtype A6 (69.6%) and subtype G (23.4%) were detected. Transmitted PI- (8.8%) and NRTI-resistance (6.4%) were detected in therapy-naive patients. In therapy-experienced patients, 17.3% of the isolates showed resistance to PIs, 50.0% to NRTI, 39.2% to NNRTIs, and 9.5% to INSTIs. Multiresistance was identified in 52 isolates, 40 corresponding to two-class resistance and seven to three-class resistance. Two resistance-associated-mutations significantly associated to sub-subtype A6 samples: A62VRT and G190SRT. This study establishes the conditions for a systematic annotation of sub-subtype A6 to normalise epidemiological studies. Accurate knowledge on South Russian epidemiology will allow for the development of efficient regional frameworks for HIV-1 infection management.
