Enhanced peer-group strategies to support the prevention of mother-to-child HIV transmission leads to increased retention in care in Uganda: A randomized controlled trial.

INTRODUCTION: Despite the scale-up of Option B+, long-term retention of women in HIV care during pregnancy and the postpartum period remains an important challenge. We compared adherence to clinic appointments and antiretroviral therapy (ART) at 6 weeks, 6, and and 24 months postpartum among pregnant women living with HIV and initiating Option B+. Women were randomized to a peer group support, community-based drug distribution and income-generating intervention called "Friends for Life Circles" (FLCs) versus the standard of care (SOC). Our secondary outcome was infant HIV status and HIV-free survival at 6 weeks and 18 months postpartum. METHODS: Between 16 May 2016 and 12 September 2017, 540 ART-naïve pregnant women living with HIV at urban and rural health facilities in Uganda were enrolled in the study at any gestational age. Participants were randomized 1:1 to the unblinded FLC intervention or SOC at enrolment and assessed for adherence to the prevention of mother-to-child HIV transmission (PMTCT) clinic appointments at 6 weeks, 12, and 24 months postpartum, self-reported adherence to ART at 6 weeks, 6 and 24 months postpartum and supported by plasma HIV-1 RNA viral load (VL) measured at the same time points, retention in care through the end of study, and HIV status and HIV-free survival of infants at 18 months postpartum. The FLC groups were formed during pregnancy within 4 months of enrollment and held monthly meetings in their communites, and were followed up until the last group participant reached 24 months post delivery. We used Log-rank and Chi-Square p-values to test the equality of Kaplan-Meier survival probabilities and hazard rates (HR) for failure to retain in care for any reason by study arm. RESULTS: There was no significant difference in adherence to PMTCT clinic visits or to ART or in median viral loads between FLC and SOC arms at any follow-up time points. Retention in care through the end of study was high in both arms but significantly higher among participants randomized to FLC (86.7%) compared to SOC (79.3%), p = 0.022. The adjusted HR of visit dropout was 2.4 times greater among participants randomized to SOC compared to FLC (aHR = 2.363, 95% CI: 1.199-4.656, p = 0.013). Median VL remained < 400 copies/ml in both arms at 6 weeks, 6, and 24 months postpartum. Eight of the 431 infants tested at 18 months were HIV positive (1.9%), however, this was not statistically different among mothers enrolled in the FLC arm compared to those in the SOC arm. At 18 months, HIV-free survival of children born to mothers in the FLC arm was significantly higher than that of children born to mothers in the SOC arm. CONCLUSIONS: Our findings suggest that programmatic interventions that provide group support, community-based ART distribution, and income-generation activities may contribute to retention in PMTCT care, HIV-free survival of children born to women living with HIV, and ultimately, to the elimination of mother-to-child HIV transmission (EMTCT).

HIV Infection, Antiretroviral Drugs, and the Vascular Endothelium.

Endothelial cell activation, injury, and dysfunction underlies the pathophysiology of vascular diseases and infections associated with vascular dysfunction, including human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome. Despite viral suppression with combination antiretroviral therapy (ART), people living with HIV (PLWH) are prone to many comorbidities, including neurological and neuropsychiatric complications, cardiovascular and metabolic diseases, premature aging, and malignancies. HIV and viral proteins can directly contribute to the development of these comorbidities. However, with the continued high prevalence of these comorbidities despite viral suppression, it is likely that ART or some antiretroviral (ARVs) drugs contribute to the development and persistence of comorbid diseases in PLWH. These comorbid diseases often involve vascular activation, injury, and dysfunction. The purpose of this manuscript is to review the current literature on ARVs and the vascular endothelium in PLWH, animal models, and in vitro studies. I also summarize evidence of an association or lack thereof between ARV drugs or drug classes and the protection or injury/dysfunction of the vascular endothelium and vascular diseases.

Community Health Care Providers' Perspectives on Human Immunodeficiency Virus Pre-Exposure Prophylaxis Use Among Black Women in Eastern Virginia.

The most at-risk population among women for human immunodeficiency virus (HIV) diagnosis in the United States are Black women, accounting for 61% of all new HIV cases. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention method for people at risk of HIV acquisition. Although disproportionately affected by HIV, Black women's knowledge, perceived benefits, and uptake of PrEP remain low. The socioecological model (SEM) may be useful for understanding why there is a low uptake of PrEP among Black women. The current study used the SEM to explore provider perspectives on the barriers and facilitators of PrEP uptake among Black women in Eastern Virginia. Semistructured interviews were conducted with a total sample of 15 community health care providers. Barriers of PrEP uptake at the societal (e.g., PrEP advertisements focus on gay men), community/organizational (e.g., time constraints in the workplace), interpersonal (e.g., perceived monogamy), and individual (e.g., unmet basic needs) levels were identified. Providers also identified facilitators of PrEP uptake at the societal (e.g., PrEP advertisements that target women), community/organizational (e.g., PrEP education), interpersonal (e.g., HIV-positive partner), and individual (e.g., PrEP awareness and perceived susceptibility to HIV) levels. These findings highlight unique barriers to accessing and taking PrEP for Black women in the United States, and potential factors that could facilitate PrEP use. Both barriers and facilitators may be important targets for interventions to improve PrEP uptake. Future research focused on improving PrEP uptake among Black women in the United States should consider multi-level interventions that target barriers and facilitators to reduce rates of HIV infections.

PROGRESO-II: Developing Culturally Tailored Materials for a Social Network-Based Intervention to Promote HIV Pre-Exposure Prophylaxis Initiation Among Latina Seasonal Farmworkers.

Latina Seasonal Farmworkers (LSFW) in South Florida are a community affected by human immunodeficiency virus (HIV) due to cultural barriers, stigma, and lack of awareness of pre-exposure prophylaxis (PrEP). Building on the PROGRESO study, this study sought to: (1) develop and pre-test scientifically supported and culturally tailored PrEP materials for PROGRESO and (2) assess the acceptability of these PrEP materials by LSFW who use alcohol and/or drugs. PrEP messages were selected based on a literature review, feedback from experts working on PrEP programs, and recommendations from a four-member scientific expert panel through a two-level Delphi method. A culturally tailored PrEP presentation was developed and presented to sixteen LSFW, who engaged in four focus groups. Materials were modified based on participants' suggestions. Thematic analysis was used to assess the acceptability and usability of these materials in the LSFW community. Participants responded positively to the PrEP messages and understood their importance for Latinx communities. Participants felt empowered and comfortable enough with the information to distribute the messages to partners, children, and friends with the aid of a physical pamphlet or flyer. A strong cultural context of familialismo and confianza was present in comments made by our participants. This study has the potential to increase LSFW's PrEP awareness and initiation. Future studies may implement a hybrid-interview approach, allowing individuals to self-select into a virtual or in-person focus group. Such flexibility may increase participation and discussion by allowing participants to attend in a format they are most comfortable with, as noted by participants in this study.

Association between smoking and lack of HIV virological suppression in a cross-sectional study of persons with HIV on antiretroviral therapy in Uganda.

BACKGROUND: Smoking and alcohol use frequently co-occur and are the leading causes of preventable death in sub-Saharan Africa (SSA) and are common among people living with HIV (PLWH). While alcohol use has been shown to be associated with reduced adherence to antiretroviral treatment (ART), which may affect HIV viral suppression, the independent effect of smoking on HIV outcomes in SSA is unknown. We aimed to 1) describe the prevalence of current smoking and correlates of smoking; 2) assess the association of smoking with viral suppression, adjusting for level of alcohol use; 3) explore the relationship between smoking and CD4 cell count <350 cells/mm3, among participants who are virally suppressed. METHODS: We analyzed data from the Drinkers Intervention to Prevent Tuberculosis (DIPT) and the Alcohol Drinkers' Exposure to Preventive Therapy for TB (ADEPTT) studies conducted in Southwest Uganda. The studies enrolled PLWH who were on ART for at least 6 months and co-infected with latent tuberculosis and dominated with participants who had unhealthy alcohol use. Current smoking (prior 3 months) was assessed by self-report. Alcohol use was assessed using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C, modified for prior 3 months) and phosphatidylethanol (PEth), an alcohol biomarker. We used logistic regression to estimate the cross-sectional association between smoking and lack of virological suppression (≥40 copies/ml), adjusting for level of alcohol use and other covariates, and to examine the association between smoking and CD4 cell counts among PLWH with viral suppression. RESULTS: Of the 955 participants enrolled from 2017 to 2021 who had viral load (VL) results, 63% were men, median age was 40 years (interquartile range [IQR] 32-47), 63% engaged in high/very high-risk alcohol use (AUDIT-C≥6 or PEth≥200 ng/mL), and 22% reported smoking in the prior 3 months. Among 865 participants (91%) with viral suppression and available CD4 count, 11% had a CD4 cell count <350 cells/mm3. In unadjusted and adjusted analyses, there was no evidence of an association between smoking and lack of virological suppression nor between smoking and CD4 count among those with viral suppression. CONCLUSIONS: The prevalence of smoking was high among a study sample of PLWH in HIV care with latent TB in Southwest Uganda in which the majority of persons engaged in alcohol use. Although there was no evidence of an association between smoking and lack of virological suppression, the co-occurrence of smoking among PLWH who use alcohol underscores the need for targeted and integrated approaches to reduce their co-existence and improve health.

Improving awareness and uptake of pre-exposure HIV prophylaxis amongst service users accessing Sexual Health London, a regional online postal sexually transmitted infection testing health service.

BACKGROUND: The UK pledged commitment to the global strategy of zero new HIV infections and HIV-related deaths by 2030. PrEP was commissioned in England in 2020 and is fundamental to achieving these targets, yet awareness and uptake are suboptimal in certain populations. METHOD: Sexual Health London (SHL) incorporated questions on its e-triage questionnaire estimating need for PrEP amongst online service users. Two types of signposting messaging were shown to users directing them to more detailed online content: PrEP-discussion (potential need) and PrEP-eligible (assumed need). The effectiveness of this signposting was evaluated by reviewing demographics and triage responses in returning users. RESULTS: 426,149 SHL users requested STI screening between 1.7.21-31.10.22. 16% (69,867/426,149) and 32.2% (137,489/426,149) of individuals received PrEP-eligible and PrEP-discussion signposting. The PrEP-eligible cohort were: 41.0% gay/bisexual or other men who have sex with men (GBMSM), 16.3% heterosexual males, 33.1% heterosexual females, and 60.6% were of white ethnicity. The PrEP-discussion cohort were: 9.3% GBMSM, 34.3%% heterosexual males, 45.5% heterosexual females and 63.7% of white ethnicity. 50.4% (35,190/69,867) and 41.3% (56,808/137,489) of the PrEP-eligible and PrEP discussion cohorts ordered a subsequent SHL STI testing kit, during which 10.0% (3510/35,190) and 5.9% (3364/56,808) reported taking PrEP. Of those who denied taking PrEP, 59% (18,702/31,680) and 61.0% (32,559/53,444) triggered PrEP signposting again. 95.4% of PrEP starters were GBMSM (6562/6874) and 1.4% (97/6874) heterosexual males/females. CONCLUSION: The e-service demonstrated feasibility in estimating PrEP need and signposting service users. Up to 16% of returning users subsequently commenced PrEP. This highlights significant missed opportunities for the remaining online users, who continue to report HIV acquisition risk(s). Further efforts regionally/nationally to optimise uptake of PrEP, particularly among under-represented groups are warranted.

Assessing index CD4 and associated outcomes at 1-year in a tertiary HIV clinic, KwaZulu-Natal.

BACKGROUND:  Human immunodeficiency virus (HIV) management guidelines have evolved from initiating therapy at CD4 counts of ≤ 200 cells/m3 to implementing universal test and treat (UTT). This study aimed to assess whether in clinical practice, patients are presenting with higher baseline CD4 counts, describe the incidence of opportunistic infections and the proportion that achieved viral suppression. METHODS:  A retrospective cohort design with convenience sampling was conducted. Cohort 1 included patients initiated on antiretroviral therapy (ART) between 01 January 2014 and 31 December 2014, when criteria were set at CD4 count ≤ 350 cells/mm3. Cohort 2 included patients initiated on ART between 01 January 2019 and 31 December 2019, during the UTT era. RESULTS:  At ART initiation, the median CD4 cell was 170 cells/mm3 (interquartile range [IQR]: 85.5-287) in Cohort 1 cells/mm3 and 243 cells/mm3 (IQR: 120-411) in Cohort 2. Tuberculosis was the predominant OI in the group with CD4 cell count ≤ 200 cells/m3 in both Cohort 1 (26.8%) and Cohort 2 (27.9%), p = 0.039. At 1 year, virological suppression was achieved in only 77.7% and 84.7% of Cohorts 1 and 2 patients. CONCLUSION:  A notable portion of patients at King Edward VIII Hospital's HIV clinic commenced ART with CD4 counts significantly below the recommended guideline thresholds.Contribution: The research revealed a delay in initiating ART. A comprehensive reevaluation is essential to pinpoint the factors contributing to this delay and to devise customised interventions.

Changes in atherosclerotic cardiovascular disease risk over time among people living with HIV.

OBJECTIVE: To describe changes in atherosclerotic cardiovascular disease (ASCVD) risk over time among people living with HIV (PLHIV). METHODS: We used data from the TREAT Asia HIV Observational Database (TAHOD) and the Australian HIV Observational Database (AHOD). Five-year ASCVD risk was calculated using the D:A:D equation. Individuals were eligible for inclusion if they were aged ≥18 years, had started ART, had no previous history of ASCVD and had complete ASCVD risk factor data available within the first 5 years of ART initiation. RESULTS: A total of 3368 adults contributed data, 3221 were from TAHOD and 147 were from AHOD. The median age at ART initiation was 36 [IQR 31-43] years for TAHOD participants, and 42 [IQR 35-50] years for AHOD participants. Most TAHOD (70.4%) and AHOD (91.8%) participants were male. Overall, ASCVD risk increased from 0.84% (95% CI 0.81%-0.87%) at ART initiation to 1.34% (95% CI 1.29%-1.39%) after 5 years on ART. After adjusting for traditional and HIV-associated ASCVD risk factors, ASCVD risk increased at a similar rate among sub-populations defined by HIV exposure (heterosexuals, men who have sex with men, people who inject drugs), race/ethnicity (Caucasian and Asian) and nadir CD4 at ART initiation (<200 and ≥200 cells/mm3). CONCLUSIONS: These findings emphasize the growing burden of ASCVD risk among PLHIV and the need to develop interventions that are effective across a broad range of HIV sub-populations.

Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.

Prevalence, treatment, and factors associated with cryptococcal meningitis post introduction of integrase inhibitors antiretroviral based regimens among People Living with HIV in Tanzania.

OBJECTIVE: This study aimed to assess the prevalence of Cryptococcal Meningitis (CM), treatment practice, and the associated factors post-introduction of Tenofovir Lamivudine and Dolutegravir (TLD) regimen among People Living with HIV (PLHIV) in Tanzania. METHODS: This was an analytical cross-sectional study, and the data was collected retrospectively in three public regional referral hospitals (RRHs) in Dar es Salaam, Tanzania. A total of 405 files of the PLHIV admitted in the medical wards on the TLD regimen from January 2019 to December 2022 were reviewed. The collected information includes the patient's demographic characteristics, Cryptococcal status, CD4 level at the time of CM diagnosis, status of using ART, CM treatment approach, and outcome. Data was analyzed using SPSS software version 23. RESULTS: Out of 405 patients, the majority 267(65.9%) were female, 224(55.3%) were aged between 36-55 years, and 293(72.3%) were married. ART defaulters were found to be 37(9.1%). The prevalence of CM was found to be 48(11.9%), out of which 42(87.5%) received fluconazole alone. ART defaulter and marital status significantly (p-value < 0.05) were associated with those who tested CM positive. CONCLUSION: The study found the prevalence of CM among PLHIV to be significantly high and the majority were treated with fluconazole alone. ART defaulters and marital status were significantly associated with one being CM positive. Responsible authorities and stakeholders should enforce guideline adherence and PLHIV should be encouraged on medication adherence.

HIV Pre-Exposure Prophylaxis Uptake Among High-Risk Population in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Globally, 38.4 million people are affected by the human immunodeficiency virus (HIV) pandemic, and more than 2.5 million new HIV infections occur yearly. HIV pre-exposure prophylaxis (PrEP) has been widely recognized as a potential way to prevent new infections among risk population. There is a paucity of abridged evidence on the level and barriers to PrEP service uptake in sub-Saharan Africa (SSA). Therefore, we conducted a systematic review to synthesize existing evidence on PrEP uptake in SSA. Relevant studies were searched from major databases (PubMed and PsychInfo) and direct Google Scholar. Data were extracted and recorded using a pilot-tested template. Methodological rigor, heterogeneity and publication bias of studies were assessed to minimize the inclusion of erroneous findings. A random effect model was used for the meta-analysis followed by narrative metasynthesis. The protocol of this systematic review has been by registered PROSPERO (ID: CRD42022308855). A total of 1830 studies were retrieved, and 30 studies met inclusion criteria of the systematic review. People who heard about PrEP ranged from 23% to 98%. The pooled prevalence of willingness to use PrEP was 64.2% (95% confidence interval: 55.5-72.0). Fear of side effect, stigma, nonreceptive attitude, cost of pills, low awareness about PrEP, perceived reason about the effectiveness of PrEP, and lack of friendly services were the common barriers to PrEP uptake in Africa. In conclusion, comprehensive knowledge and willingness to use PrEP were low in SSA. The barriers to low PrEP service uptake are avoidable through comprehensive awareness creation and availing essential services to key population in Africa. Expanding educational messages to key population using friendly approaches and more accessible platforms, engaging stakeholders, and integrating PrEP service with routine health care are important to foster HIV prevention and control in the future.

Markedly increased duodenal villous surface apoptosis in patients taking pre-exposure prophylaxis (PrEP) against human immunodeficiency virus.

AIMS: Pre-exposure prophylaxis (PrEP) consists of combination antiretroviral therapy and is increasingly utilized to prevent human immunodeficiency virus (HIV) in high-risk populations. Two index cases noted during routine care showed markedly increased duodenal villous surface apoptosis in patients on PrEP. We sought to examine the prevalence of this finding and identify any clinicopathologic correlations. METHODS: Gastrointestinal biopsy specimens from 23 male patients aged 18-40 years taking PrEP and 23 control patients were reviewed. Patients with HIV, inflammatory gastrointestinal diseases, and celiac disease were excluded. Apoptoses were counted on surface epithelium and deep crypts. The highest apoptotic body count per tissue fragment was recorded. Clusters were defined as groups of ≥5 apoptoses. Apoptotic counts between patients taking PrEP and controls were compared using t-tests. RESULTS: In PrEP patients, the median age was 35 years (range 25-40) and 83% (19/23) were white. The control patients were demographically similar (median age: 32 years [range 23-40]; 70% [16/23] white). Duodenal apoptosis in villous surface epithelium was increased in PrEP patients, with 14/23 (60.9%) patients having ≥10 surface apoptoses compared to 2/23 (8.7%) controls (P = 2.1 × 10-3 ) and 14/23 (61%) having clusters compared to 3/23 (13%) controls (P = 2.0 × 10-3 ). There was no significant association between increased surface apoptosis or clusters and clinical symptoms or duration of PrEP use. CONCLUSION: Markedly increased villous surface apoptosis, particularly in clusters, is often seen in the duodenum of patients taking PrEP. Although the mechanism and significance are unknown, knowledge of this peculiar finding may prevent unnecessary additional testing.

Impact of an HIV pre-exposure prophylaxis dashboard on veteran PrEP enrollment.

BACKGROUND: Pre-exposure prophylaxis (PrEP) is highly effective at reducing the risk of human immunodeficiency virus (HIV) acquisition in at-risk individuals; however, it is largely underutilized. The Veterans Health Administration has created an HIV PrEP dashboard to identify at-risk veterans in attempt to increase PrEP enrollment. OBJECTIVE: This study aimed to determine whether the use of an HIV PrEP dashboard would prove effective at increasing PrEP enrollment at a single facility. METHODS: This was a single-center quality improvement project. Three pharmacists used the HIV PrEP dashboard and retrospective chart review to identify eligible patients for PrEP. A multimodal process of contacting patients was conducted. The primary objective was to evaluate the number of patients who enrolled in PrEP during the study period. Secondary objectives included evaluating the ability of the HIV PrEP dashboard to identify eligible patients, identify effective strategies to target PrEP enrollment, and compare those patients who accepted with those who declined PrEP to evaluate barriers to enrollment. RESULTS: Of the 94 patients reviewed, 26 patients (27.7%) were found eligible for PrEP. Of the eligible patients, 3 patients (11.5%) were enrolled, and 7 patients (26.9%) declined PrEP. The others were lost to follow-up (9 of 26, 34.6%), had no action taken on a chart note to provider (6 of 26, 23.1%), or did not have a primary care provider assigned at the local facility (1 of 26, 3.9%). The 3 patients who were successfully enrolled in PrEP were all contacted and prescribed PrEP through the infectious diseases (ID) clinic. There were no statistically significant differences between the cohorts of patients who accepted and declined PrEP. CONCLUSIONS: The use of an HIV PrEP dashboard aided in identifying eligible patients for PrEP. Enrollment through the ID clinic was the most successful modality. Further research is needed to characterize barriers to PrEP uptake and to develop strategies to increase prescribing from non-ID providers.

People living with HIV's perspectives of acceptability of fee for home delivery of ART: a qualitative study.

INTRODUCTION: Significant progress has been made in the HIV response in South Africa; however, gaps remain in ensuring engagement in care to support life-long medication adherence and viral suppression. The National Department of Health (NDoH) has introduced community-based and clinic-based HIV differentiated service delivery (DSD) models to tackle suboptimal adherence and retention in care. Nevertheless, differentiated care models require adaptation to better serve clients who struggle with adherence. There is limited research on the acceptability of fee for home delivery of ART in resource-constrained settings. The current study investigates the acceptability of fee for home delivery of ART among people living with HIV in South Africa. METHODS: Two mixed-gender focus group discussions (FGDs) took place between June and November 2019, consisting of 10 participants in each group. A purposive sampling strategy was employed to identify and select 10 people living with HIV who were ART-eligible but not in care, and 10 people living with HIV who were currently taking ART and in care. Participants were grouped according to their treatment status. A coding framework, informed by a priori categories and derived from topics in the interview guide, was developed and utilized to facilitate analysis. RESULTS: Participants expressed enthusiasm for having ART home-delivered, as it would save the time spent waiting in long queues at the clinic. However, some participants raised concerns about potential payment difficulties due to high unemployment rates in the community. Some participants believed this would be acceptable, as patients already incur costs for travel and food when visiting the clinic. Participants in both FGDs expressed strong concerns about home delivery of their ART based on fear of accidental disclosure, especially for those who have not disclosed to their immediate families and partners. CONCLUSION: Our study suggests that charging a fee for home delivery is an acceptable and innovative approach to supporting PLHIV in maintaining adherence to their medication and remaining in care.

Virological, weight, and drug resistance outcomes among patients initiating a dolutegravir-based first-line antiretroviral therapy regimen in Zimbabwe.

OBJECTIVE: Dolutegravir (DTG)-based antiretroviral therapy (ART) is being scaled up in Africa. However, clinical experience with DTG and patterns of HIV drug resistance (HIVDR) are sparse in Zimbabwe. We assessed virological, weight, and HIVDR outcomes among individuals initiating on a DTG-based ART. DESIGN: We conducted a prospective cohort study among HIV-infected adult (≥18 years old) individuals attending care at Parirenyatwa hospital, Harare, Zimbabwe between October 2021 and April 2023. METHODS: Viral load and weight were assessed at both baseline and follow-up (≥24weeks) visits. HIVDR genotyping was performed by Sanger sequencing among participants with virological failure (viral load ≥1000 copies/ml) at follow-up visit. Factors associated with weight gain were determined using logistic regression analysis on STATA 17.0. RESULTS: One hundred and seventy-two participants were enrolled in the study. The median [interquartile range (IQR) age was 39 (29-48)] years whilst the median (IQR) CD4 + cell count and log 10 viral load at enrolment was 175 (58-328) cells/µl and 5.41 (4.80-5.74), respectively. After a median (IQR) duration of 27 (25-30) weeks on DTG, of the 131 participants with follow-up viral load data available, 129 (98%) had viral load less than 1000 copies/ml and among the 2 (2%) participants with viral load at least 1000 copies/ml, no emergent HIVDR was detected. We observed a significant increase in weight among the participants. The average weight gain was 5.25 kgs ( P  < 0.0001). Baseline CD4 + cell count at least 200 cells/µl was significantly associated with at a smaller weight gain [odds ratio (OR) = 0.26; 95% confidence interval (CI) 0.12-0.58, P  = 0.001]. CONCLUSION: We found high virological suppression and an increased weight among people initiating on DTG in a resource-limited setting. Encouragingly, HIVDR to DTG remains rare.

[Presentations for HIV post-exposure prophylaxis in emergency departments: guideline and recommendations]. / HIV-Postexpositionsprophylaxe in der Notaufnahme: Vorgehen, Tipps & Tricks.

Patients often present to emergency departments after potential or confirmed exposure to human immunodeficiency virus (HIV) asking for recommendations concerning the initiation of post-exposure prophylaxis (PEP). These presentations may occur after occupational as well as non-occupational exposure. PEP entails taking a triple antiretroviral therapy for 28-30 days. If taken early (ideally within 2 h, but no later than 72 h) and as indicated, HIV infection can be prevented with a high level of probability. Since these presentations occur around the clock, they require basic expertise on the part of the emergency department staff regarding its indication and its side effects as well as standardized procedures in the emergency department to not delay initiation. Patients should present to an infectious disease outpatient clinic or practice specialized in HIV in order to have the indication reviewed by a specialist and, if necessary, adapted to complex cases with the aim of making individual case decisions. This review article aims to summarize core statements of the 2022 German-Austrian guideline on HIV post-exposure prophylaxis and to give emergency department staff necessary knowledge to safely and correctly begin PEP.

Anemia, iron, and HIV: decoding the interconnected pathways: A review.

This review delves into the intricate relationship between anemia, iron metabolism, and human immunodeficiency virus (HIV), aiming to unravel the interconnected pathways that contribute to the complex interplay between these 3 entities. A systematic exploration of relevant literature was conducted, encompassing studies examining the association between anemia, iron status, and HIV infection. Both clinical and preclinical investigations were analyzed to elucidate the underlying mechanisms linking these components. Chronic inflammation, a hallmark of HIV infection, disrupts iron homeostasis, impacting erythropoiesis and contributing to anemia. Direct viral effects on bone marrow function further compound red blood cell deficiencies. Antiretroviral therapy, while essential for managing HIV, introduces potential complications, including medication-induced anemia. Dysregulation of iron levels in different tissues adds complexity to the intricate network of interactions. Effective management of anemia in HIV necessitates a multifaceted approach. Optimization of antiretroviral therapy, treatment of opportunistic infections, and targeted nutritional interventions, including iron supplementation, are integral components. However, challenges persist in understanding the specific molecular mechanisms governing these interconnected pathways. Decoding the interconnected pathways of anemia, iron metabolism, and HIV is imperative for enhancing the holistic care of individuals with HIV/AIDS. A nuanced understanding of these relationships will inform the development of more precise interventions, optimizing the management of anemia in this population. Future research endeavors should focus on elucidating the intricate molecular mechanisms, paving the way for innovative therapeutic strategies in the context of HIV-associated anemia.

The Association of HIV Control and Immunosuppression With Risk of Non-AIDS-Defining Cancer Risk Among Patients on Antiretroviral Therapy.

BACKGROUND: People living with HIV (PWH) are experiencing an increased prevalence of non-AIDS-defining cancers (NADCs). Our study investigated the association of immunosuppression and HIV control with NADCs among PWH on antiretroviral therapy (ART) in the United States. METHODS: Among patients across 8 clinical cohorts on ART between 1996 and 2016, we assessed immune function and HIV control using 3 parameterizations of CD4 count and HIV-RNA viral load (VL): (1) CD4 or VL at ART initiation; (2) change in CD4 or VL after ART initiation; and (3) proportion of follow-up time at CD4 >500 cells/µL or VL <50 copies/mL. Cox models were used to ascertain the association of these measures with risk of a viral NADC or nonviral NADC. RESULTS: Among 29,568 patients on ART, there were 410 nonviral NADCs and 213 viral NADCs. PWH with a CD4 <200 cells/µL at ART initiation had an 80% elevated risk for developing a viral NADC. Each increase of 100 cells/µL in CD4 after ART initiation decreased risk by 14%. For viral and nonviral NADCs, 10% more follow-up time spent with a CD4 >500 cells/µL was associated with decreased risk [viral, adjusted hazard ratio (aHR): 0.82; 95% confidence intervals (CI): 0.78 to 0.86; nonviral, aHR: 0.88; 95% CI: 0.86 to 91], even after accounting for CD4 at ART initiation. When examining HIV control only, 10% more time with VL <50 copies/mL was significantly associated with decreased viral (aHR: 0.85; 95% CI: 0.82 to 0.89) and nonviral NADC risk (aHR: 0.88; 95% CI: 0.85 to 0.90). CONCLUSIONS: This study demonstrates that even for PWH on ART therapy, maintaining HIV control is associated with lower risk of both viral and nonviral NADCs.

Drastic Reduction in Time to Controlled Viral Load in People With Human Immunodeficiency Virus in France, 2009-2019: A Longitudinal Cohort Study.

BACKGROUND: Aspirational targets to end AIDS by 2030 include having 95% of people with human immunodeficiency virus (HIV; PWH) diagnosed, 95% treated, and 95% with controlled viral load (VL). Our objective was to describe, using a large French prospective cohort, the median transition times through the cascade of care between 2009 and 2019. METHODS: We analyzed patients whose first HIV diagnosis was made between 1 January 2009 and 31 December 2019. Using the Kaplan-Meier method, we estimated the time to linkage to care (from HIV diagnosis to first biological assessment), to treatment (date of first antiretroviral therapy [ART] prescription), and to controlled VL (first value <200 copies/mL). Analyses were disaggregated by time periods and patients' characteristics. Censoring date was 31 December 2021. RESULTS: Among the 16 864 patients linked to care since 2009, the median [Q1; Q3] time from HIV diagnosis to controlled VL decreased from 254 [127-745] to 73 [48-132] days in 2009-2011 and 2018-2019, respectively. Transition times from linkage to care to first ART decreased from 67 [17; 414] in 2009-2011 to 13 [5; 26] days in 2018-2019, and from ART to controlled VL from 83 [35; 130] in 2009-2011 to 38 [28; 90] days in 2018-2019. Differences were observed depending on patients' characteristics. CONCLUSIONS: We describe drastic reductions in transition time through the cascade of care, allowing reduction in the transmission period following each new infection. Delayed diagnosis remains the main obstacle to ending AIDS in the next decade.
