High Human Immunodeficiency Virus Burden Research Articles

Spatial distribution and determinants of HIV high burden in the Southern African sub-region.

Spatial analysis at different levels can help understand spatial variation of human immunodeficiency virus (HIV) infection, disease drivers, and targeted interventions. Combining spatial analysis and the evaluation of the determinants of the HIV burden in Southern African countries is essential for a better understanding of the disease dynamics in high-burden settings. The study countries were selected based on the availability of demographic and health surveys (DHS) and corresponding geographic coordinates. We used multivariable regression to evaluate the determinants of HIV burden and assessed the presence and nature of HIV spatial autocorrelation in six Southern African countries. The overall prevalence of HIV for each country varied between 11.3% in Zambia and 22.4% in South Africa. The HIV prevalence rate was higher among female respondents in all six countries. There were reductions in prevalence estimates in most countries yearly from 2011 to 2020. The hotspot cluster findings show that the major cities in each country are the key sites of high HIV burden. Compared with female respondents, the odds of being HIV positive were lesser among the male respondents. The probability of HIV infection was higher among those who had sexually transmitted infections (STI) in the last 12 months, divorced and widowed individuals, and women aged 25 years and older. Our research findings show that analysis of survey data could provide reasonable estimates of the wide-ranging spatial structure of the HIV epidemic in Southern African countries. Key determinants such as individuals who are divorced, middle-aged women, and people who recently treated STIs, should be the focus of HIV prevention and control interventions. The spatial distribution of high-burden areas for HIV in the selected countries was more pronounced in the major cities. Interventions should also be focused on locations identified as hotspot clusters.

Safe sex negotiation and HIV risk reduction among women: A cross-sectional analysis of Burkina Faso 2021 Demographic and Health Survey.

Women are biologically more susceptible to the Human Immunodeficiency Virus (HIV) and other sexually transmitted Infections (STIs) because receptive sex is riskier than insertive. Despite condom use being the staple preventive method for HIV infection (over 80% efficacy), in Sub-Saharan African countries like Burkina Faso, a high burden of HIV and the unmet need for condom use coexist. Moreover, even though women in SSA are disproportionately HIV positive, they are reportedly less capable of negotiating condom use for HIV risk reduction. Thus, using the Health Believe Model (HBM), this study explored the factors that influence condom use among women within the context of HIV prevention, with a key interest in condom use negotiation. Using the women's dataset of the 2021 Burkina Faso Demographic and Health Survey and applying logistic regression models, this study examined the factors associated with condom use for HIV risk reduction. Women who had confidence to negotiate condom use with their partners (OR = 1.57, P<0.001, 95%CI: 1.29, 1.91), those with secondary education (OR = 1.38, P<0.05, 95%CI: 1.07 1.77), from richest households (OR = 1.64, P<0.05, 95%CI: 1.08, 2.47), the employed (OR = 1.23, P<0.05, 95%CI: 1.02, 1.49), women with knowledge of sexually transmitted infections (OR = 1.58, P<0.001, 95%CI: 1.26, 1.97), those who have ever been tested for HIV (OR = 1.85, P<0.001, 95%CI: 1.52 2.24), as well as those who knew that a healthy-looking person can have HIV (OR = 2.64, P<0.001, 95%CI: 2.15, 3.24) were all significantly more likely to practice condom use for HIV risk reduction. Also, religion and geographical location of participants significantly predicted condom use for HIV risk reduction in the study context. The ability to negotiate condom use, knowledge of HIV and STIs, the socioeconomic status of women, as well as their geographical location, influence their practice of safer sex for HIV risk reduction in Burkina Faso.

Fast-track interventions for HIV and AIDS epidemic control among key populations: A rapid review.

Targeted interventions for key populations remain critical for realisation of epidemic control for human immunodeficiency virus (HIV) infection because of the causal relationship between HIV infection in the general population and among key population groups. To consolidate evidence on the fast-track interventions towards achieving HIV epidemic control among key populations. A rapid scoping review was conducted using the methodological framework by Arksey and O' Malley. The Population, Intervention, Context and Outcome (PICO) framework was used to identify relevant studies using key words with Boolean operators in electronic data bases, namely CINHAL, Web of Science, Psych Info and Sabinet. Studies were extracted using a modified data extraction tool, and results were presented narratively. A total of 19 articles were included in this review. Most articles were primary studies (n = 17), while another involved the review of existing literature and policies (n = 2) and routinely collected data (n = 1). Most studies were conducted in the United States of America (n = 6), while another were conducted in China, Kenya, Botswana, South Africa and Mozambique. All studies revealed findings on tested interventions to achieve HIV epidemic control among key populations. Effective interventions for HIV epidemic control were stand-alone behavioural preventive interventions, stand-alone biomedical preventive strategies and combination prevention approaches. Furthermore, the findings suggest that effective activities to achieve HIV epidemic control among key populations should be centred around prevention.Contribution: The findings of this study have policy and practice implications for high HIV burden settings such as South Africa in terms of interventions to facilitate realisation of the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets, thereby contributing to HIV epidemic control.

Health Screening Strategies for Artisanal and Small-Scale Miners for Tuberculosis, Human Immunodeficiency Virus and Silicosis: A Case of the USAID-Supported Kunda Nqob'iTB Project in Zimbabwe.

Artisanal and small-scale mining is characterized by excessive exposure to physical, chemical, ergonomic, psychosocial and biological hazards. There is a high burden of tuberculosis (TB), human immunodeficiency virus (HIV) infections and silicosis among artisanal and small-scale miners (ASMs). The aim of this project report is to describe lessons learned from strategies implemented to reach ASMs with screening services for TB, HIV and silicosis in Zimbabwe through the Kunda-Nqob'i TB (KNTB) project supported by the United States Agency for International Development (USAID). The intervention package for screening ASMs for TB, HIV and silicosis included service provision through two occupational health clinics at two provincial hospitals and a mobile workplace-based screening (WBS) facility at the mining sites. From 1 October 2020 to 30 September 2023, 10,668 ASMs were screened, with a high number of cases of silicosis (21%) and TB (7.4%). There was a high burden of HIV (30%) in ASMs attending the occupational health clinics. The two occupational health clinics screened 3453 ASMs, while the mobile WBS activities screened 7215 ASMs during the period. A total of 370 healthcare workers (doctors/clinical officers, nurses, environmental health technicians and district tuberculosis and Leprosy control officers) were trained on TB and the fundamental diagnostic principles of silicosis. The KNTB project has been successful in reaching out to many ASMs operating in remote and hard-to-reach mining areas. The KNTB project has brought to light the positive health-seeking behavior of ASMs operating in remote areas. The project has brought to the fore the effectiveness of multi-stakeholder engagement and collaboration in reaching out to ASMs in remote areas with health screening services. There is a high burden of TB, HIV and silicosis in ASMs. Screening for TB, HIV and silicosis using workplace-based screening and occupational health clinics is an effective strategy and should be rolled out to all areas with high artisanal and small-scale mining activity.

HIV Infection and Associated Factors Among Out-of-School MSM Aged 16-24 Years - 6 Cities and Tianjin Municipality, China, 2022-2023.

Approximately 80% of newly diagnosed human immunodeficiency virus (HIV) cases among individuals aged 15-24 years in China are attributed to out-of-school youth. This study presents findings on HIV prevalence and comprehensive insights into HIV service utilization, risky behaviors, and prevention knowledge among young out-of-school men who have sex with men (MSM) aged 16-24 years in China. This population exhibits a disproportionately high burden of HIV, with only 51.6% of HIV cases previously diagnosed. HIV services should be expanded to include these key populations. Tailored interventions are needed to remove barriers to regular HIV services faced by young key populations.

Costing of HIV services, Uganda and United Republic of Tanzania.

To evaluate resource allocation and costs associated with delivery of human immunodeficiency virus (HIV) services in Uganda and the United Republic of Tanzania. We used time-driven activity-based costing to determine the resources consumed and costs of providing five HIV services in Uganda and the United Republic of Tanzania: antiretroviral therapy (ART); HIV testing and counselling; prevention of mother-to-child transmission; voluntary male medical circumcision; and pre-exposure prophylaxis. Country-based teams undertook time-driven activity-based costing with 1119 adults in Uganda and 886 adults in the United Republic of Tanzania. In Uganda, service delivery costs ranged from 8.18 United States dollars (US$) per visit for HIV testing and counselling to US$43.43 for ART (for clients in whom HIV was suppressed). In the United Republic of Tanzania, these costs ranged from US$3.67 per visit for HIV testing and counselling to US$28.00 for voluntary male medical circumcision. In both countries, consumables were the main cost driver, accounting for more than 60% of expenditure. Process maps showed that in both countries, registration, measurement of vital signs, consultation and medication dispensing were the steps that occurred most frequently for ART clients. Establishing a rigorous, longitudinal system for tracking investments in HIV services that includes thousands of clients and numerous facilities is achievable in different settings with a high HIV burden. Consistent engagement of implementation partners and standardized training and data collection instruments proved essential for the success of these exercises.

Modeling one-stop-shop integration of family planning and HIV services in Zimbabwe, 2021

Objectives: In October 2020, the Ministry of Health and Child-care Zimbabwe commenced integrating reproductive health with human immunodeficiency virus (HIV) services. Family planning (FP), sexually transmitted infection (STI) screening and treatment, HIV testing services (HTS), pre-exposure prophylaxis (PrEP), and antiretroviral therapy (ART) services were offered through an integrated one-stop-shop model. The project aimed to address unacceptably high incidences of HIV and STIs among FP clients and demonstrate improved access and uptake of integrated services at dedicated FP centers. Materials and Methods: We conducted an intervention study. A service package of STI symptom screening and HTS (including HIV self-test [HIVST] primary and secondary distribution) was offered to all FP clients by multi-skilled nurses. Service uptake was measured pre and post-introduction of the intervention, before which services were provided by different nurses, in different rooms. HIV-diagnosed clients were linked to ART and eligible negative testers were offered PrEP. Service uptake was measured at 1 year of implementation against the same period before. Results: A total of 20,947 clients were recruited between October 2019 and September 2021, 9386 pre-intervention and 11,561 post-intervention. We observed a 5.2% total increase in clients seen and a 27.1% increase in the average uptake of all integrated services (FP, STI, HTS, PrEP, and ART). Most (93.5%) clients received oral contraception (Progestogen-only pills and combined-oral-contraceptives), while fewer (4.8%) received injectables and implants (1.1%). Following the intervention, STI screening increased by 30.2% (2730 vs. 11,028). HTS delivery increased by 38.9% and PrEP by 44.1%. HIV positivity yield increased significantly (10.1%, 62/615 vs. 16.6%, 813/4910) and linkage to ART improved by 44.4%. HIVST distribution contributed to improved access to HIV testing with 3754 FP clients accepting distribution compared with 4910 receiving HTS by nurses, provider-delivered testing was accessed by reactive self-testers. The project increased (?) improved linkage to preventive and treatment services and reduced missed opportunities associated with fragmented services. Conclusion: The integrated one-stop-shop model demonstrated improved service uptake during the intervention period. This project shows the benefits of integrated FP/STI/HTS/PrEP in Zimbabwe’s high HIV burden settings.

The Testing Imperative: Why the US Ending the Human Immunodeficiency Virus (HIV) Epidemic Program Needs to Renew Efforts to Expand HIV Testing in Clinical and Community-Based Settings.

Data from several modeling studies demonstrate that large-scale increases in human immunodeficiency virus (HIV) testing across settings with a high burden of HIV may produce the largest incidence reductions to support the US Ending the HIV Epidemic (EHE) initiative's goal of reducing new HIV infections 90% by 2030. Despite US Centers for Disease Control and Prevention's recommendations for routine HIV screening within clinical settings and at least yearly screening for individuals most at risk of acquiring HIV, fewer than half of US adults report ever receiving an HIV test. Furthermore, total domestic funding for HIV prevention has remained unchanged between 2013 and 2019. The authors describe the evidence supporting the value of expanded HIV testing, identify challenges in implementation, and present recommendations to address these barriers through approaches at local and federal levels to reach EHE targets.

Barriers To Early Infant Diagnosis And Service Delivery In Two High Hiv Districts In Ghana

Objective: Ghana has made significant progress in its efforts to control Human Immunodeficiency virus (HIV) infections, however 31% of HIV exposed infants received early infant diagnosis (EID) services. This paper examines the factors influencing EID service delivery in two high HIV burden districts in Ghana.&#x0D; Methodology: This study was conducted in two districts in the Eastern region of Ghana, Lower Manya Krobo (LMK) District (high HIV burden with low EID coverage) and New Juabeng Municipality, NJM (high HIV burden with relatively higher coverage for EID). This analysis describes the first phase (exploratory study) of a three-phased implementation research spanning over 24 months. A total of 420 women with children &lt; 2 years in each study area were involved. Key informant interviews and focus group discussions were conducted among mothers and health workers.&#x0D; &#x0D; Data (quantitative and qualitative) were analysed with appropriate statistical measures.&#x0D; Results: Relatively more women from LMKD knew about the risks for mother-to-child transmission of HIV (83.6% vs. 79.8%) and more women in LMKD had children &lt;2 years tested for HIV. In contrast to findings from the survey, knowledge on EID during Focus Group Discussions was better in NJM than LMKD. Major demand and supply -side barriers and challenges to EID were identified. &#x0D; Conclusion: Health system (supply side) and community based (demand side) barriers mitigated against the EID coverage in the two districts. More community sensitisation, improved innovative means of transporting samples and effective tracking of mothers with HIV exposed infants and linking them up to care is recommended.

Changes of human immunodeficiency virus (HIV) burden globally and in China over three decades: a secondary analysis of global HIV statistics.

A more comprehensive understanding of the trends of incidence, prevalence, and mortality in human immunodeficiency virus (HIV), and their complex interrelationships, may provide important evidence for decision-making related to HIV prevention and control. The variances in these indices between different population groups, genders, and ages are critical to decipher evolving patterns of the HIV epidemic in specific populations. A secondary analysis of relevant data was conducted using data extracted from the Global Burden of Disease study of 2019. HIV/acquired immune deficiency syndrome (AIDS) incidence, prevalence, AIDS-related mortality, and mortality-to-prevalence ratio (MPR) for annual percentage change, average annual percentage change (AAPC), and corresponding 95% confidence intervals (CIs) were calculated using joinpoint regression statistical analysis. The AAPC of HIV/AIDS incidence, prevalence, AIDS-related mortality rate, and MPR were -1.4 (95% CI: -1.6, -1.2), 4.1 (95% CI: 4.0, 4.3), 2.0 (95% CI: 1.7, 2.3), and -2.1 (95% CI: -2.3, -1.8) between 1990 and 2019 globally, and were 3.5 (95% CI: 2.2, 4.8), 6.9 (95% CI: 6.8, 7.0), 8.1 (95% CI: 7.1, 9.1), and 1.2 (95% CI: 0.1, 2.3) in China during the same period. In terms of differences in the preceding indicators by gender, we observed a similar pattern of trends for male and female genders both globally and in China during the entire study period. Each specific age group exhibits a distinct pattern in terms of incidence, prevalence, mortality rate, and MPR both globally and in China. Prevalence and mortality rates of HIV/AIDS have increased between 1990 and 2019 globally and in China. While the incidence rate and MPR have declined globally over the past three decades, these two indicators are observed to present an increasing trend in China. There is a high HIV burden among young and middle-aged adults globally; however, the elderly have a high HIV burden in China. HIV screening at older age should be scaled up, and patients with advanced HIV disease should be provided early with additional care and health resources.

Magnitudes and Correlates of Human Immunodeficiency Virus, Hepatitis B Virus, and Syphilis among Pregnant Mothers Attending Antenatal Care in Addis Ababa, Ethiopia.

Background Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis are major sexually transmitted infections (STIs) among the general population in Ethiopia, which in turn result in a wide range of adverse pregnancy outcomes. Hence, it is important to determine the seroprevalence and risk factors of HIV, HBV, and syphilis infection among pregnant mothers attending antenatal care in Addis Ababa, Ethiopia. Method A cross-sectional study was conducted among 286 pregnant women from February 1, 2021, to March 30, 2021, in four selected public hospitals in Addis Ababa. Sociodemographic, risky sociocultural, behavioral, and hospital-related factors were collected using an interview-administered questionnaire. Detection of anti-HIV antibodies, hepatitis B surface antigen (HBsAg), and rapid plasma reagin (RPR) for syphilis was conducted. A binary logistic regression analysis was used to determine predictors of STIs using SPSS version 25. Result A total of 281 pregnant mothers with a mean age of 27.5 (SD 4.6) completed the study. Among the participants, the seroprevalence rates of HIV, HBV, and syphilis were 15 (5.3%), 9 (3.2%), and 5 (1.8%), respectively. Twenty six (9.3%) of the participants tested positive for any one of the STIs, and 3 (1.1%) of the women had HIV and syphilis coinfections. History of multiple sexual partners (AOR 3.42, 95% CI: 1.6-11.63) and STIs (AOR 3.7; 95% CI: 1.70-13.45) were significantly associated with HIV infection. Likewise, history of abortion (AOR 7.65, 95% CI: 1.17-49.74), tattooing (AOR 9.72, 95% CI: 1.41-66.73), and rape (AOR 9.72, 95% CI: 1.41-66.73) were significantly associated with hepatitis B virus infection. Husband history of multiple sexual partners (AOR 20.9, 95% CI: 1.8-241.8) was significantly associated with syphilis infection. The educational level of participants, history of tattooing (AOR 6.24, 95% CI: 1.79-21.7), and history of multiple sexual partners (AOR 5.15, 95% CI: 1.68-15.7) were independent predictors of infection with any one of the STIs. Conclusion There is still a high burden of HIV, HBV, and syphilis among pregnant mothers in Ethiopia. History of multiple sexual partners, abortion, rape, and tattooing was a significant predictor of STIs.

Incidence, treatments, and outcomes of SARS-CoV-2 and HIV co-infections

Background We investigated the global threat of co-infection of severe acute respiratory coronavirus 2 (SARS-CoV-2) to patients living with another prevalent viral infection HIV. We have analyzed symptom status, treatment, and outcome of co-infected individuals. Methods An extensive literature search of PubMed, preprint databases (bioRxiv, medRxiv, and preprints), and ClinicalTrials.gov was conducted from 1 December 2019 to 28 February 2021. Ninety-two potential studies involving 39,461 HIV and SARS-CoV-2 co-infected patients were analyzed with details of severity, their treatment, and the outcomes. Results A total of 39,461 cases of people living with HIV have reported co-infection with SARS-CoV-2 worldwide. Of these coinfected individuals, the symptom status for 3,213 patients (~8%) was available, out of which 44% were severely/critically ill. The collated data show the fatality rate for human immunodeficiency virus (HIV) and SARS-CoV-2 coinfection to be 2.4% and a large proportion was found to have several comorbidities. The most commonly administered antiretroviral therapy to the people living with HIV was tenofovir/emtricitabine; these drugs are already in phase 3 clinical trials for coronavirus disease 2019 (COVID-19). We observed that majority of co-infected patients who survived were those on tenofovir/emtricitabine combination drug therapy for HIV. Conclusions The current study demonstrates that patients with HIV may have worse outcomes due to COVID-19 than the general population. However, the HIV/SARS-CoV-2 coinfection needs to be analyzed across multiple countries with a high burden of HIV, and with a much larger cohort to gain a better understanding of the impact of SARS-CoV-2 on people living with HIV.

Patient outcomes in integrated HIV and non-communicable disease models of care: a scoping review

Background High rates of non-communicable diseases (NCD) among people living with human immunodeficiency virus (HIV) have been reported in high HIV burden, low-resource settings. The growing dual burden of HIV and NCD epidemics has necessitated introduction of integrated models of HIV and NCD care in order to leverage existing HIV care infrastructure for NCDs. There is a paucity of evidence on the effects of integrated care on long-term patient outcomes. We sought to review literature that described effects of integration on long-term patient outcomes. Methods We reviewed literature published between 01 Jan 2000 to 25 September 2019, that described long-term patient outcomes in HIV and NCD integrated models of care in order to understand the effects of integration on long-term patient outcomes. Relevant literature was searched in PubMed, Scopus, EBSCOhost and Web of Science. A manual search of abstracts in the International AIDS Society and the Journal of Acquired Immunodeficiency Syndrome was also conducted. Results One thousand six hundred and sixty articles were identified, 31 of which were read in full, with 11 meeting eligibility criteria. Patient outcomes in four models of integrated care were identified: (i) integration of NCD screening and treatment services into established HIV centres; (ii) integration of HIV screening and treatment services into established NCD centres; (iii) simultaneous integration of HIV and NCD services at health facilities; and (iv) integrated HIV and NCD care specifically for multi-morbid patients. Studies reported high rates of control of HIV and NCD across the various models of integrated care. However, majority of studies lacked comparator groups required to ascertain non-inferiority of integrated care over non-integrated care. Conclusions There is limited evidence on the effect of integrated HIV and NCD models of care on long-term patient outcomes especially in low-resource, high-burden settings. Randomized clinical trials with clearly defined comparator groups and standardized measures of HIV and NCD outcomes are needed to demonstrate non-inferiority of integrated against non-integrated care.

Sero-epidemiology and associated factors of HIV, HBV, HCV and syphilis among blood donors in Ethiopia: a systematic review and meta-analysis

BackgroundTransfusion transmissible infections (TTIs) remain a major public health problem in developing countries including Ethiopia. In Ethiopia, comprehensive information about sero-epidemiology of major TTIs is lacking at the national level. Therefore, this systematic review and meta-analysis was aimed at providing the pooled estimate of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis among blood donors in Ethiopia.MethodsRelevant studies published until May 31, 2019 were searched through PubMed/Medline, EMBASE, SCOPUS, HINARI, Cochrane database library, Web of Science, Google Scholar and Google. The methodological quality of articles was assessed using Joanna Brigg’s Institute critical appraisal checklist for prevalence and analytical studies. The pooled sero-epidemiology of HIV, HBV, HCV and syphilis were determined using the random-effects model. Heterogeneity between the studies was assessed using the I2 statistics. Publication bias was assessed by visual inspection of the funnel plot and Egger's statistics.ResultsA total of 7921 articles were retrieved, and 7798 were screened for eligibility after duplicates removed. Forty-nine full-text articles were assessed for eligibility; of which 45 were eligible for qualitative and quantitative synthesis: categorized as 36, 34, 31 and 23 studies for estimations of HBV, HIV, HCV and syphilis, respectively. In the random-effects model, the pooled sero-epidemiology of HBV, HIV, HCV and syphilis was 5.20, 2.83, 0.93 and 1.50%, respectively. Moreover, being a male blood donor was significantly associated with HBV and syphilis infection, whereas being a replacement blood donor was significantly associated with a high burden of HIV, HBV and HCV infections.ConclusionThe pooled sero-epidemiology of major TTIs among blood donors was high. Therefore, there is a need to design prevention and control strategies in a comprehensive approach to reduce the burden.

Role of direct and indirect social and spatial ties in the diffusion of HIV and HCV among people who inject drugs: a cross-sectional community-based network analysis in New Delhi, India.

People who inject drugs (PWID) account for some of the most explosive human immunodeficiency virus (HIV) and hepatitis C virus (HCV) epidemics globally. While individual drivers of infection are well understood, less is known about network factors, with minimal data beyond direct ties. 2512 PWID in New Delhi, India were recruited in 2017-19 using a sociometric network design. Sampling was initiated with 10 indexes who recruited named injection partners (people who they injected with in the prior month). Each recruit then recruited their named injection partners following the same process with cross-network linkages established by biometric data. Participants responded to a survey, including information on injection venues, and provided a blood sample. Factors associated with HIV/HCV infection were identified using logistic regression. The median age was 26; 99% were male. Baseline HIV prevalence was 37.0% and 46.8% were actively infected with HCV (HCV RNA positive). The odds of prevalent HIV and active HCV infection decreased with each additional degree of separation from an infected alter (HIV AOR: 0.87; HCV AOR: 0.90) and increased among those who injected at a specific venue (HIV AOR: 1.50; HCV AOR: 1.69) independent of individual-level factors (p<0.001). In addition, sociometric factors, for example, network distance to an infected alter, were statistically significant predictors even when considering immediate egocentric ties. These data demonstrate an extremely high burden of HIV and HCV infection and a highly interconnected injection and spatial network structure. Incorporating network and spatial data into the design/implementation of interventions may help interrupt transmission while improving efficiency.

Treatment outcomes of Gene Xpert positive tuberculosis patients in KwaMashu Community Health Centre, KwaZulu-Natal, South Africa: A retrospective review

BackgroundWe sought to investigate the relationship between tuberculosis (TB) treatment outcomes and its predictors in the KwaMashu region in KwaZulu-Natal (KZN). This area is currently a hotbed for TB and human immunodeficiency virus (HIV) co-infection.MethodA retrospective study design was adopted to characterise adult patients diagnosed with Gene Expert (GXP) positive pulmonary TB from 01 January 2016 to 31 December 2017. Tuberculosis treatment outcomes were assessed after two months and five months according to the standard World Health Organization (WHO) criteria. Multiple logistic regression analysis was used to calculate the odds ratio (OR) of the possible determinants associated with unsuccessful treatment outcomes.ResultsAmongst the 596 patients diagnosed, 57.4% (95% confidence interval [CI]: 53.3–61.4; 342 of 596) had successful treatment outcomes. Of these reported cases, 88.89% (85.1–92.0; 304 of 342) were cured. For the unsuccessful treatment outcomes, 52.4% (46.0–58.6; 133 of 254) patients were lost to follow-up, 20.9% (16.0–26.4; 53 of 254) failed treatment, 1.2% (0.2–3.4; 3 of 254) died and 25.6% (20.3–31.4; 65 of 254) of the patients could not be accounted for. Patients with unknown HIV status were more likely to have unsuccessful treatment outcomes (adjusted OR [aOR] = 4.94 [1.83–13.36]). Patients who had sputum conversion at 2 months (aOR = 1.94 [1.27–2.96]) were significantly more likely to exhibit unsuccessful treatment outcomes.ConclusionTreatment success rate was 57.4% which was below the target set by the WHO. This underscores the urgent need to strengthen treatment adherence strategies to improve outcomes, especially in high HIV burden settings.

Tailoring Communication to Increase the Promotion of Oral PrEP: A Culture-Centred Approach

In Sub-Saharan Africa, human immunodeficiency virus (HIV) incidence rates remain disproportionately high among adolescent girls and young women (AGYW), who are five to seven times more likely to contract HIV than their male peers. Following the 2015 World Health Organization (WHO) Guideline on When to Start Antiretroviral Therapy and on Pre-Exposure Prophylaxis (PrEP) for HIV, the South African Department of Health (DoH) released the National Policy on HIV PrEP and Test and Treat (T&T) in June 2016. At the time of writing, several demonstration projects were underway to assess the feasibility of oral PrEP for AGYW in South Africa, with extensive access for sex workers and limited access for AGYW. It is within this context that the article explores the current perceptions of oral PrEP utilising the data from two previous studies conducted in three high HIV burden districts in KwaZulu-Natal (KZN), South Africa. Through an analysis of the current perceptions of oral PrEP, the article prioritises the cultural communication imperative to promote inclusivity and acceptability of biomedical innovations. The article argues that communication about oral PrEP is embedded in cultural discourses that must be discussed, critiqued and incorporated into a new framework for combination HIV prevention.

Safety and Effectiveness of an All-Oral, Bedaquiline-Based, Shorter Treatment Regimen for Rifampicin-Resistant Tuberculosis in High Human Immunodeficiency Virus (HIV) Burden Rural South Africa: A Retrospective Cohort Analysis.

BackgroundAt the end of 2018, South Africa updated its all-oral regimen, to include bedaquiline (BDQ) and 2 months of linezolid (LZD) for all patients initiating the shorter 9–12 months regimen for rifampicin-resistant tuberculosis (RR-TB). We assessed a group of patients in rural KwaZulu-Natal for safety and effectiveness of this treatment regimen under programmatic conditions.MethodsWe conducted a retrospective cohort analysis on RR-TB patients treated with a standardized all-oral short regimen between 1 July 2018 and 30 April 2019 in 3 facilities in King Cetshwayo District. An electronic register (EDR web) and facility-based clinical charts were used to collect variables, which were entered into an Epi-Info database.ResultsOur cohort included 117 patients; 68.4% (95% confidence interval [CI]: 59.3–76.3) tested positive for human immunodeficiency virus (HIV). The median time to culture conversion was 56 days (95% CI: 50–57). Treatment success was achieved in 75.2% (95% CI: 66.5–82.3) of patients. Mortality within the cohort was 12.8% (95% CI: 7.8–20.3). Anemia was the most frequent severe adverse event (AE). The median time to develop severe anemia was 7.1 weeks (interquartile range [IQR] 4.0–12.9) after treatment initiation. LZD was interrupted in 25.2% (95% CI: 17.8–34.5) of participants.ConclusionsAn all-oral shorter regimen, including BDQ and LZD as core drugs for the treatment of RR-TB, shows good outcomes, in a high HIV burden rural setting. AEs are common, especially for LZD, but could be managed in the program setting. Support is needed when introducing new regimens to train staff in the monitoring, management, and reporting of AEs.

Effect of pregnancy and HIV infection on detection of latent TB infection by Tuberculin Skin Test and QuantiFERON-TB Gold In-Tube assay among women living in a high TB and HIV burden setting

ObjectiveTo investigate the effect of pregnancy and Human immunodeficiency virus (HIV) infection on detection performances of tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube (QFTGIT) for the diagnosis of latent tuberculosis infection (LTBI) among women living in high TB and HIV endemic setting. MethodA cross-sectional study was conducted among women with and without pregnancy and HIV infection. Three-hundred twenty women were enrolled in this study and were diagnosed using TST and QFTGIT for the detection of LTBI. ResultsOverall prevalence of LTBI among the enrolled women was 55.6%, 46.3% and 51.1% as determined by TST, QFTGIT and concordant TST/QFTGIT results, respectively. Our study revealed that pregnancy or HIV infection reduced the rate of detection of LTBI by TST and QFTGIT tests, with the utmost effect observed in HIV-positive pregnant women. Additionally, we observed that the concordance between TST and QFTGIT among women increased with the presence of pregnancy and/or HIV infection. A history of contact with TB patients was significantly associated with positivity of TST and QFTGIT. ConclusionThis study demonstrated that both pregnancy and HIV infection profoundly affected the detection performance of TST and QFTGIT, which may be associated with immunosuppression of anti-mycobacterial immunity in women with pregnancy and/or HIV infection.

Population prevalence of sexually transmitted infections in a high HIV burden district in KwaZulu-Natal, South Africa: Implications for HIV epidemic control

BackgroundSexually transmitted infections (STIs) and Human immunodeficiency virus (HIV) share a complex bidirectional relationship, however, population prevalence and the association between the presence of STIs and HIV in a high HIV burden district in KwaZulu-Natal, South Africa is not known. MethodsA total of 9812 participants aged 15–49 years were enrolled in a cross-sectional population-based household survey. Participants completed a structured questionnaire and provided first-pass urine (males) or self-collected vulvo-vaginal swabs (females) for the detection of STIs. ResultsPrevalence of herpes simplex virus type-2 (HSV-2) was 57.8%, syphilis was 1.6%, Neisseria gonorrhoeae was 2.8%, Chlamydia trachomatis was 7.1%, Trichomonas vaginalis was 9.0%, Mycoplasma genitalium was 5.5% and HIV was 36.3%. HIV positive status was associated with an increased probability of having M. genitalium (aPR = 1.49, 95% CI 1.02–2.19) among males and syphilis (aPR = 2.54, 95% CI 1.32–4.86), N. gonorrhoeae (aPR = 2.39, 95% CI 1.62–3.52), T. vaginalis (aPR = 1.70, 95% CI 1.43–2.01) and M. genitalium (aPR = 1.60, 95% CI 1.15–2.22) among females. HIV viral load ≥400 copies per mL was associated with an increased probability of N. gonorrhoeae (aPR = 1.91, 95% CI 1.36–2.70), C. trachomatis (aPR = 1.52, 95% CI 1.12–2.05) and M. genitalium (aPR = 1.83, 95% CI 1.27–2.63). ConclusionsThe high prevalence of STIs and the association between STIs and HIV, and HIV viral load underscores the public health implications of sustained transmission risk of STIs and HIV. These findings highlight the urgent need for expanding STI surveillance and implementing interventions to monitor and reduce the STI burden.
