HIV-infection in the Russian Federation: current diagnostic trends

The aim of the study: to analyse diagnostic trends of HIV-infection in the Russian Federation in the period 2017–2022. Materials and methods. The study used data obtained from reports from the Federal Register of persons infected with the human immunodeficiency virus (FRHIV). The circumstances in HIV diagnosis and clinical and epidemiological characteristics of newly diagnosed patients, including CD4+ T-lymphocyte counts, were analysed. A likely time window between presumed infection and confirmation of HIV diagnosis was also determined. Categorical data evaluated in the study were presented as proportions and caparisoned using the chi-square test (χ2). In case of multiple comparisons, the Bonferroni correction for multiplicity was used. Quantitative data were tested for normality using the Kolmogorov-Smirnov criterion. In most cases, nonparametric characteristics of distributions — median and interquartile range — were applied, as well as the Mann-Whitney criteria for comparison of two independent groups and the Kraskell-Wallis criteria for comparison more than two groups, followed by pair wise comparisons using the Mann-Whitney criterion with Bonferroni multiplicity correction. A p-value<0.05 was considered statistically significant. Data analysis and graphical visualization was performed using the statistical software R version 4.1.1 and its libraries.Results and discussion. The results showed an increase in HIV detection through voluntary testing, preventive medical examination, and clinical indications. The proportion of injecting drug users (IDUs) decreased over time, while the involvement of women in the epidemic process and heterosexual transmission increased. Additionally, there was an increase in the proportion of patients aged 35 years and older. The analysis of CD4-cell counts revealed significant differences among gender and age subgroups. Women had higher absolute CD4-lymphocyte counts throughout the follow-up period. Patients aged 0–14 years had the highest proportion of CD4-lymphocytes over 500 cells/μL, while patients over 50 years old had the highest proportion of CD4-lymphocytes less than 200 cells/μL. Men who have sex with men and people infected through mother-to-child transmission had the highest mean baseline CD4-cell counts. IDUs and heterosexuals had a statistically significant decrease in CD4-cell counts over the follow-up period and also had the longest median time from infection to disease detection — 24 and 20 months, respectively.Conclusion: Thus, this study helps identify the most significant risk groups of HIV-infected individuals in Russia at present.

Diagnosis and presenting features of autoimmune hepatitis at a central referral hospital in South Africa.

Introduction Autoimmune hepatitis (AIH) has scarcely been reported on in patients of black African descent. Similarly, few studies have focused on the relationship between AIH and Human-Immunodeficiency Virus (HIV) infection. Aim We aim to describe the presenting features of AIH from a single referral centre in a Sub-Sahara African setting. We also compare the presenting features of HIV-infected and HIV-uninfected patients. Methods This study was a retrospective chart review. Patients were included if they fulfilled criteria for the International AIH Group simplified score for probable or definite AIH, were 18 years or older at inclusion, and attended the adult Gastroenterology clinic at Inkosi Albert Luthuli Central Hospital (IALCH) for the period 1/1/2015 to 31/12/2020 on at least 2 occasions. Results Forty cases were included, of which 33 (82.5%) were female and 33 (82.5%) were black African. Median age at diagnosis was 26 years. A diagnosis of a coexistent autoimmune disease was made in 22.5% of patients, with Systemic Lupus Erythematosus (SLE) being the most common (12.5%). Sixteen patients were HIV-infected, all of whom were female (p =0.03), with a significantly older age of disease onset as compared to their HIV-uninfected counterparts (median age 38 vs 17.5 years, p <0.001). Conclusion AIH is a disease most commonly affecting young females. Female sex and older age of onset is associated with AIH in HIV-infected individuals.

A remarkable genetic shift in a transmitted/founder virus broadens antibody responses against HIV-1

A productive HIV-1 infection in humans is often established by transmission and propagation of a single transmitted/founder (T/F) virus, which then evolves into a complex mixture of variants during the lifetime of infection. An effective HIV-1 vaccine should elicit broad immune responses in order to block the entry of diverse T/F viruses. Currently, no such vaccine exists. An in-depth study of escape variants emerging under host immune pressure during very early stages of infection might provide insights into such a HIV-1 vaccine design. Here, in a rare longitudinal study involving HIV-1 infected individuals just days after infection in the absence of antiretroviral therapy, we discovered a remarkable genetic shift that resulted in near complete disappearance of the original T/F virus and appearance of a variant with H173Y mutation in the variable V2 domain of the HIV-1 envelope protein. This coincided with the disappearance of the first wave of strictly H173-specific antibodies and emergence of a second wave of Y173-specific antibodies with increased breadth. Structural analyses indicated conformational dynamism of the envelope protein which likely allowed selection of escape variants with a conformational switch in the V2 domain from an α-helix (H173) to a β-strand (Y173) and induction of broadly reactive antibody responses. This differential breadth due to a single mutational change was also recapitulated in a mouse model. Rationally designed combinatorial libraries containing 54 conformational variants of V2 domain around position 173 further demonstrated increased breadth of antibody responses elicited to diverse HIV-1 envelope proteins. These results offer new insights into designing broadly effective HIV-1 vaccines.

Emergence of HIV-1 drug resistance mutations among children and adolescents undergoing prolonged antiretroviral therapy in Guangxi

Antiretroviral therapy (ART) has been implemented in Guangxi for a long time, and there are no reports of HIV drug resistance mutation (DRM) among children and adolescents experiencing virologic failure after ART. This study aimed to analyse HIV DRM prevalence, patterns, and influencing factors among children and adolescents experiencing virologic failure after ART in Guangxi. We collected samples from a total of 491 HIV-infected individuals under 18 years old experiencing virologic failure after ART from 14 cities in Guangxi. Sequencing and DRM analysis were performed based on pol region. Multivariate logistic regression was employed to analysis the influencing factors of DRM. Among these patients, 396 cases were successfully sequenced. Of all, 52.53% exhibited HIV DRM, including NNRTI (48.48%), NRTI (34.85%) and PI (1.01%). NRTI and NNRTI dual-class resistance was prevalent (30.3%). M184V/I and K103N mutations were the common mutations in NRTI and NNRTI, respectively. Male sex (aOR = 2.1, 95% CI: 1.26-3.50), CRF01_AE subtype (OR = 2.50, 95% CI: 1.02-5.88), the primary regimen 3TC+AZT+NVP (OR = 10.00, 95% CI: 5.00-25.00), low pretreatment CD4+ T lymphocytes (<200 cells/mm³) (OR = 1.85, 95% CI: 1.00-3.45), and high viral load (>1000 copies/mL) (OR = 4.90, 95% CI: 1.03-23.39) showed higher risk of DRM. HIV DRM is pervasive among children and adolescents experiencing virologic failure in Guangxi. Timely HIV DRM monitoring is crucial to mitigate major mutation accumulation and inform effective treatment strategies.

Predominant amino acid substitutions in NS5B gene of hepatitis C virus in blood donors and treatment-naïve hepatitis and HIV patients in Nigeria

Background: Hepatitis C virus (HCV) genome undergoes high rate of mutation, which results in generation of genetically diverse HCV isolates. There is paucity of data on mutations in the nonstructural 5b (NS5b) gene of circulating HCV and their implications in the Nigerian population. Here, we identified clinically-important mutations in HCV isolates, which may influence response to therapy and disease prognosis.&#x0D; Methodology: HCV RNA was extracted from a total of 301 blood samples collected from 99 symptomatic treatment-naïve hepatitis patients, 125 HIV-infected individuals and 77 asymptomatic blood donors in Ibadan, Nigeria. The RNA was reverse–transcribed to complimentary DNA and HCV NS5B gene amplified by nested PCR. The amplified products of 42 HCV were sequenced and sequences were aligned with those from GenBank and HCV databases in MEGA 7.0. Nucleotide sequences were translated to amino acids while substitutions in the amino acids were analyzed with reference to H77 prototype strain of HCV.&#x0D; Results: A total of 10 amino acid polymorphisms were observed from the 42 sequenced NS5B gene, with the major clinically-important amino acid mutations being S15G in 28 (66.7%) participants, T7N (24, 57.1%), G61R (23, 54.8%), S54L (22, 52.4%), G89E (14, 33.3%), T79M (12, 28.6%), and T711 (11, 26.2%). Others were Q67R (7, 16.7%), Q47H (7, 16.7%) and S84F (2, 4.8%). S15G/A/V mutations were more predominant in patients with HIV (76.9%, 10/13) followed by patients with clinical hepatitis (75.0%, 12/16) and blood donors (46.1%, 6/13). Q67R and T71I mutations were not predominant in patients with clinical hepatitis as they were detected in only 31.3% (5/16) and 43.8% (7/16) participants respectively, compared to S15G (75.0%, 12/16), S54L (68.8%, 11/16), G61R/E (68.8%, 11/16) and T7N/S (56.3%, 9/16). There was no statistically significant difference in the distribution of each of the 10 amino acid polymorphisms detected within patients with symptomatic clinical hepatitis (x2=9.311, p=0.409), HIV-infected patients (x2=13.431, p=0.1440) and asymp- tomatic blood donors (x2=3.775, p=0.9256). Similarly, there was no significant difference in the distribution between the 3 categories of the study participants except for T79M mutation, which was significantly higher in HIV-infected patients (61.5%, 8/13) compared to patients with clinical hepatitis (18.8%, 3/16) and asymp- tomatic blood donors (7.7%, 1/13) (x2=10.456, p=0.0054).&#x0D; Conclusion: Mutations in the NS5B gene could be associated with worse prognosis of the disease or antiviral failure due to viral resistance in patients undergoing therapy. The absence of Q47H mutations in majority of the study participants in our study implies that they will not respond well to daprevir and mericitabine. Screening of patients for pre-existing resistant mutations before commencement of therapy and monitoring during and after therapy are recommended.

IJCM_288A: Factors responsible for death among HIV infected patients registered in ART Centre Jabalpur, Madhya Pradesh.

Background: Factors responsible for death in HIV infected population are necessary to devise disease specific preventive interventions at both state and national level HIV programs. This study examines the factors responsible for death among HIV-infected individuals registered in Anti-Retro-viral Therapy (ART) center Jabalpur, Madhya Pradesh. Objectives: 1. To understand the trends of HIV deaths in last 6 years in Jabalpur District. 2. To understands the factors responsible for deaths among registered HIV positive patients in ART Centre of Jabalpur District. Methodology: A retrospective chart review of factors responsible for death was undertaken among HIV-infected patients who were treated between January 2016 and December 2021 at ART Center Jabalpur. Results: Among total of 83 sample cases registered from January 2016 to December 2021, 86.7% of those who died were males. Mean duration of survival after initiation of treatment is 17 months. 49.4% of the cases falls under the age group of 31-45 years. 75.9% of the cases contracted the virus through sexual mode of transmission. 56.6% of the cases had opportunistic infections. Tuberculosis is (32.5%) is the leading opportunistic infections and 28.9% of cases had CD4 count in the range of 50-199 cells/mm. Conclusion: Tuberculosis has remained the leading factor responsible for deaths among the HIV patients on ART. Deaths were significantly associated with patient’s CD4 count at the time of diagnosis and the presence of opportunistic infections during treatment.

Semen Washing and Intrauterine Insemination for Reducing the Risk of Human Immunodeficiency Virus Transmission in Serodiscordant Couples: A Cross-sectional Study.

Antiretroviral therapy has helped human immunodeficiency virus (HIV)-infected people live an enhanced quality of life and attempt for a pregnancy, without placing their partner at risk. Although periconceptional pre-exposure prophylaxis for the uninfected partner and consistent antiretroviral therapy for the HIV-infected partner are important to prevent HIV transmission, semen washing could be a great option to further reduce the semen viral load. The aim of this study were as follows: to determine if semen washing with intrauterine insemination provides an added safety net to HIV-serodiscordant couples when the male partner is HIV-infected and virally suppressed and to determine if the U = U concept (undetectable = untransmittable) holds true in virally suppressed HIV-infected males. This was an observational study conducted in seropositive HIV men under treatment with highly active antiretroviral therapy (HAART) in collaboration with Metropolis Laboratory, a CAP recognised private Healthcare Laboratory in Mumbai, India. Blood and semen samples were collected from a total of 110 adult HIV-1-infected males virally suppressed on HAART. These samples were processed to assess the viral load in plasma as well as raw and processed semen fractions. Descriptive statistics were used to analyse the data. Only men with plasma viral loads < 1000 copies were selected in our study. Out of the 110 HIV-infected individuals, 102 (92.73%) patients had undetectable (<20 copies/ml) plasma viral load while 8 (7.27%) patients had a detectable (>20 copies/ml) viral load, who were excluded from the study. In the virally suppressed 102 men, the raw semen samples of 100 men showed an undetectable viral load, while 2 samples showed detectable contamination, even though their plasma samples from the blood showed a viral load of <20 copies/ml. The semen was then separated into the sperm and the seminal plasma samples. The seminal plasma had <20 copies/ml in 95 samples (93.14%) but a detectable viral load in 7 (6.86%) samples. After subjecting all the 102 processed (post-wash) sperm samples to quantitative analysis, an undetectable viral load of <20 copies/ml was found in all the samples. Thus, the raw sample (prewashed),seminal plasma and processed (postwash) samples were evaluated. The post-wash sperm sample showing zero contamination was frozen for intrauterine insemination (IUI) in the uninfected female partner. Semen washing with IUI should be advocated as a safe, efficacious way to increase the safety net and to further reduce the minimal risk of HIV transmission in serodiscordant couples in addition to the U = U concept.

Cerebrospinal Fluid Viral Escape on Highly Active Antiretroviral Therapy: Analysis from Single Tertiary Care Centre.

HIV-infected individuals receiving regular antiretroviral therapy (ART) can present with a high viral load in cerebrospinal fluid (CSF) at times when it is suppressed in blood. This study presents data of HIV-infected patients who had undetectable or low plasma viral load in blood but presented with neurological signs and symptoms and were diagnosed to have CSF HIV viral escape. Records were reviewed for clinical manifestations, details of opportunistic or coinfection, and HIV viral copies in plasma and CSF at time of diagnosis of CSF escape. A total of 10,200 HIV-infected individuals were registered in HIV care till December 31, 2021. Nineteen individuals (14 virologically confirmed and 5 clinically) were diagnosed with high viral copies in CSF from June 2014 to December 2021. Mean age was 41.5 ± 9.2 (median, 39.5; range, 30-62) years. Average duration of antiretroviral treatment received at the time of diagnosis of CSF escape was 10.1 years. Median plasma HIV-viral copies were 2,469.8 (undetectable to 29,418) and in CSF were 12,773.7 (n = 14, range, 1,340-48,530) copies/mL. HIV viral copies in CSF were significantly higher than in plasma at the time of presentation (p = .003). ART regimen switch was done after identification of HIV CSF escape. Seventeen patients were alive with a regular follow-up of average 35 (range 7-66) months. All had documented clinical improvement with reversal of neurological impairment after ART switch. There was one death and one lost to follow-up. Early identification and timely intervention in CSF viral escape could revert severe neurological impairment and improves treatment outcome.

A Co-infection Model for Monkeypox and HIV/AIDS: Sensitivity and Bifurcation Analyses

Monkeypox can make people very sick. The skin becomes infected with bacteria, thus causing severe skin damage. This can lead to corneal infection with loss of vision, pneumonia, difficulty swallowing, diarrhoea and vomiting leading to harsh malnutrition or dehydration, several organs inflammation or death. HIV-AIDS is a life-threatening and chronic condition. In HIV-infected individuals whose immune systems have been compromised, monkeypox mortality alone may be much higher. The co-infection of monkeypox and HIV/AIDS infections has been studied from a mathematical perspective by constructing a 13-compartment deterministic model. Basic mathematical analyses were performed on the co-infection model and the sub-models. The disease equilibrium points, the non-negativity of solutions, the basic reproduction numbers, the invariant region and the stability patterns. When the basic reproduction number is less than unity, the disease-free equilibrium points of each sub-model are globally asymptomatically stable. Certain calculations were done using the maple 18 programming language. The sensitivity analysis reveals that the parameters of the basic reproduction of the monkeypox sub-model with positive sensitivity indices are the probability of catching the monkeypox virus, the rate of effective contact, the compartment Im ’s coefficient of infection and the monkeypox vaccine’s waning rate, while the parameters of the basic reproduction of the HIV/AIDS sub-model with positive sensitivity indices are the probability of catching HIV virus, the rate effective contact, the compartment Ih ’s coefficient of infection and the compartment Ah ’s coefficient of infection. Via the centre manifold theorem, the bifurcation analysis reveals a forward bifurcation pattern for the monkeypox sub-model and the HIV/AIDS sub-model, and under a certain condition, a critical value of the monkeypox basic reproduction exists such that an effective management and possible elimination of the monkeypox infection would require that the monkeypox basic reproduction number should be kept below unity and above the critical value.

Platelet index ratios in HIV: Emerging biomarkers for immune health and disease management.

Human Immunodeficiency Virus (HIV) infection is a global health challenge that requires continuous advancements in diagnostic and prognostic tools. Traditional markers, such as CD4 cell counts and viral load, have played a crucial role in monitoring disease progression and guiding therapeutic interventions. However, emerging research suggests that platelet index ratios may serve as valuable biomarkers in assessing immune health and managing HIV-associated complications. This paper explores the significance of platelet index ratios, including platelet-to-lymphocyte ratio and mean platelet volume-to-lymphocyte ratio, as potential indicators of immune system status in individuals living with HIV. The interplay between platelets, lymphocytes, and their ratios reflects the dynamic nature of the immune response and inflammatory processes during HIV infection. Understanding the role of platelet index ratios in HIV could lead to the development of accessible and cost-effective biomarkers for monitoring immune health. Implementation of these ratios in routine clinical practice may enhance the precision of disease prognosis and guide personalized treatment strategies. Additionally, the exploration of platelet index ratios may pave the way for innovative therapeutic interventions aimed at modulating immune responses in HIV-infected individuals. In conclusion, platelet index ratios represent promising emerging biomarkers for evaluating immune health and managing HIV-related complications. Further research and clinical validation are warranted to establish the utility of these ratios in routine HIV care, potentially revolutionizing the approach to monitoring and improving the health outcomes of individuals living with HIV.

The Social Problem of HIV as a Driver for the Development of Psychological Science and Practice

This article presents an analysis of Eugene V. Farber’s2 speech at the annual convention of the American Psychological Association in 2017. The social and psychological aspects of the HIV epidemic problem, contributing to the development of psychological science and practice, are discussed. The role of HIV-infection in the development of psychological science and practice. Among these problems are stigmatization, doctor-patient relationship, mental disorders, and behavioral changes arising in HIV-infected individuals. Humanization and contextualization of clinical counseling, transformation of medical services taking into account cultural diversity and the implementation of a patient-centered approach in the clinical environment are mentioned to be the key trends in working with HIV-infected individuals

Scaling-up and scaling-out the Systems Analysis and Improvement Approach to optimize the hypertension diagnosis and care cascade for HIV infected individuals (SCALE SAIA-HTN): a stepped-wedge cluster randomized trial.

Undiagnosed and untreated hypertension is a main driver of cardiovascular disease and disproportionately affects persons living with HIV (PLHIV) in low- and middle-income countries. Across sub-Saharan Africa, guideline application to screen and manage hypertension among PLHIV is inconsistent due to poor service readiness, low health worker motivation, and limited integration of hypertension screening and management within HIV care services. In Mozambique, where the adult HIV prevalence is over 13%, an estimated 39% of adults have hypertension. As the only scaled chronic care service in the county, the HIV treatment platform presents an opportunity to standardize and scale hypertension care services. Low-cost, multi-component systems-level strategies such as the Systems Analysis and Improvement Approach (SAIA) have been found effective at integrating hypertension and HIV services to improve the effectiveness of hypertension care delivery for PLHIV, reduce drop-offs in care, and improve service quality. To build off lessons learned from a recently completed cluster randomized trial (SAIA-HTN) and establish a robust evidence base on the effectiveness of SAIA at scale, we evaluated a scaled-delivery model of SAIA (SCALE SAIA-HTN) using existing district health management structures to facilitate SAIA across six districts of Maputo Province, Mozambique. This study employs a stepped-wedge design with randomization at the district level. The SAIA strategy will be "scaled up" with delivery by district health supervisors (rather than research staff) and will be "scaled out" via expansion to Southern Mozambique, to 18 facilities across six districts in Maputo Province. SCALE SAIA-HTN will be introduced over three, 9-month waves of intensive intervention, where technical support will be provided to facilities and district managers by study team members from the Mozambican National Institute of Health. Our evaluation of SCALE SAIA-HTN will be guided by the RE-AIM framework and will seek to estimate the budget impact from the payer's perspective. SAIA packages user-friendly systems engineering tools to support decision-making by frontline health workers and to identify low-cost, contextually relevant improvement strategies. By integrating SAIA delivery into routine management structures, this pragmatic trial will determine an effective strategy for national scale-up and inform program planning.

Navigating the Nexus: HIV and Breast Cancer-A Critical Review.

Despite significant advances in the management of antiretroviral therapy (ART), leading to improved life expectancy for people living with HIV (PLWH), the incidence of non-AIDS-defining cancers, including breast cancer, has emerged as a critical concern. This review synthesizes current evidence on the epidemiology of breast cancer among HIV-infected individuals, highlighting the potential for an altered risk profile, earlier onset, and more advanced disease at diagnosis. It delves into the molecular considerations underpinning the relationship between HIV and breast cancer, including the role of immunosuppression, chronic inflammation, and gene expression alterations. Additionally, it examines the complexities of managing breast cancer in the context of HIV, particularly the challenges posed by ART and anticancer agents' cross-toxicities and drug-drug interactions. The review also addresses survival disparities, underscoring the need for improved cancer care in this population. By identifying gaps in knowledge and areas requiring further research, this review aims to illuminate the complexities of HIV-associated breast cancer, fostering a deeper understanding of its epidemiology, molecular basis, and clinical management challenges, thereby contributing to better outcomes for individuals at the intersection of these two conditions. This narrative review systematically explores the intersection of HIV infection and breast cancer, focusing on the impact of HIV on breast cancer risk, outcomes, and treatment challenges.

Incidence of diabetes and influencing factors in HIV-infected individuals after antiretroviral therapy in Dehong Dai and Jingpo Autonomous Prefecture

Objective: To understand the incidence of diabetes and influencing factors, the trend of FPG change and risk for mortality in HIV-infected individuals after antiretroviral therapy (ART) in Dehong Dai and Jingpo Autonomous Prefecture (Dehong). Methods: The HIV/AIDS treatment database was collected from China Information System for Disease Control and Prevention. This retrospective cohort study was conducted in HIV-infected individuals with access to ART in Dehong during 2004-2020.The Cox proportional hazard regression model was used to analyze the incidence density of diabetes, the influencing factors and risk for mortality in HIV-infected individuals with access to ART, mixed linear effects model was used to analyze the trend of FPG change and predict FPG in those with different glucose metabolic status at baseline survey. Statistical analysis was performed using software SAS 9.4. Results: A total of 8 763 HIV-infected individuals were included, in whom 8 432 (96.2%) had no diabetes, 331 had diabetes. The incidence density of diabetes was 2.31/1 000 person years. Multivariate Cox proportional hazard regression analysis revealed that 30- 59 years old, BMI ≥24.0 kg/m2, Efavirenz (EFV) based initial treatment regimen and impaired fasting glucose (IFG) at baseline survey were significantly and positively associated with incidence of diabetes. Mixed effect model revealed that FPG was positively correlated with the duration of ART, age and baseline FPG. Suffering from diabetes was a risk factor for mortality in HIV-infected individuals both at baseline survey and during follow-up. Conclusions: The risk for diabetes increased in HIV-infected individuals who were 30-59 years old, baseline BMI ≥24.0 kg/m2, received EFV based initial treatment, and IFG in HIV-infected individuals after antiretroviral therapy in Dehong, 2004-2020. It is important to pay close attention to their blood glucose, and patients with high blood glucose should receive treatment as early as possible.

Prevention and infection control of HIV infection and AIDS

Background: Although the global incidence of human immunodeficiency virus (HIV) has decreased significantly since modern antiretroviral therapy (ART), new HIV infections steadily occur, in the Republic of Korea. Based on the understanding of the risk factors for HIV infection, combined strategic behavioral and biomedical interventions should be implemented to reduce HIV infection. This paper reviews the strategies for the prevention of HIV infection.Current Concepts: While the consistent use of latex condoms is effective for the prevention of HIV transmission, consistent use of condoms is low among sexually active individuals. ART can be initiated, after exposure, to prevent HIV infection (post-exposure prophylaxis) after occupational or sexual exposure, injection drug use, and other nonoccupational exposures to HIV. There is a negligible risk of sexual transmission of HIV when the HIV-infected sexual partner has durably suppressed viral replication with ART. Antiretroviral agents have been shown to be highly effective when administered prophylactically to HIV-uninfected but at-risk individuals (preexposure prophylaxis). A high-risk group, such as men who have sex with men, is required to be included in health insurance care benefits for pre-exposure prophylaxis, in addition to the current partners of HIV-infected individuals, to ensure its efficacy.Discussion and Conclusion: HIV-related deaths are rapidly decreasing, but new HIV infections continue to occur. In an environment where a cure or the development of vaccines is unlikely, a multifaceted and proactive approach is required to minimize new HIV infections.

The prevalence of urogenital tuberculosis in people living with HIV

The prevalence of urogenital tuberculosis (UGT) is not well known, especially in people living with HIV, therefore, our aim was to identify the prevalence of urogenital tuberculosis in HIV-infected individuals and characterize the clinical and laboratory risk factors associated with UGT. A cross sectional study was conducted to characterize the prevalence of UGT in people living with HIV. PCR tests and specific culture were performed on samples from 181 patients living with HIV, divided into two groups: A) patients with suggestive UGT symptoms and b) hospitalized patients without any suggestive UGT symptoms. Only one case of UGT was diagnosed, with a positive PCR but negative specific culture, resulting in a prevalence of 0.55%. The patient had disseminated tuberculosis (miliary pulmonary, intestinal, and urogenital with bilateral nephromegaly) with acute febrile syndrome, no urogenital symptoms, but with microscopic hematuria and sterile pyuria. This patient had poorly controlled HIV infection with positive viral load and CD4 count below 200 cells/mm³. The prevalence of UGT in patients living with HIV is very low. However, patients with poorly controlled disease may present disseminated tuberculosis associated with UGT. Urine screening for UGT may be relevant for diagnosing disseminated tuberculosis in patients living with HIV with acute infectious syndrome.

The problems of counteraction to HIV-infection and its prevention in places of imprisonment

The article considers the problem of organizing prevention and treatment of HIV-infection in suspected, accused and convicted persons in places of deprivation of liberty. The HIV-infected individuals in places of deprivation of liberty are in situation of increased risk that creates objective necessity for in-depth study of this phenomenon. The purpose of the study was to determine specific characteristics of organization of support of HIV-infected individuals, to identify ways of contamination and its main risk factors among both suspected, accused and convicted persons and penitentiary institution personnel. The study provided sorting out of main aspects that resulting in convicts' refusal to receive drugs and treatment. The corresponding recommendations for optimizing general and particular prevention of these negative phenomena were developed. The conclusion was made that it is possible to apply complex methods to motivate convicted HIV patients for treatment. Some of these methods can include such medical social psychological measures of organizational managerial character as training of specialists; participation of HIV patients in comprehensive preventive programs; group support of convicted HIV patients; positive reinforcement application; individual approach.
