RESUMO
Twenty-eight individuals who experienced proximal renal tubulopathy (PRT, Fanconi syndrome) while receiving tenofovir disoproxil initiated tenofovir alafenamide (TAF) and were followed for 5 years. None developed recurrent PRT or experienced significant changes in estimated glomerular filtration rate (by creatinine or cystatin-C), albuminuria, proteinuria, retinol-binding proteinuria, fractional excretion of phosphate, alkaline phosphatase, or bone mineral density at the lumbar spine. These data suggest that TAF is a well tolerated treatment option for individuals vulnerable to developing PRT.

OBJECTIVE: Metabolic dysfunction associated fatty liver disease (MAFLD) is over-represented in people with HIV (PWH). Maraviroc (MVC) and/or metformin (MET) may reduce MAFLD by influencing inflammatory pathways and fatty acid metabolism. DESIGN: Open-label, 48-week randomized trial with a 2âxâ2 factorial design. SETTING: Multicenter HIV clinics. PARTICIPANTS: Nondiabetic, virologically suppressed PLWH, aged at least 35âyears, with confirmed/suspected MAFLD (≥1âbiochemical/anthropometric/radiological/histological features). INTERVENTION: Adjunctive MVC; MET; MVC+MET vs. antiretroviral therapy (ART) alone. PRIMARY OUTCOME: Change in liver fat fraction (LFF) between baseline and week-48 using magnetic resonance proton density fat fraction (MR PDFF). RESULTS: Six sites enrolled 90 participants (93% male; 81% white; median age 52 [interquartile range, IQR 47-57] years) between March 19, 2018, and November 11, 2019. Seventy percent had imaging/biopsy and at least one 1 MAFLD criteria. The analysis included 82/90 with week-0 and week-48 scans. Median baseline MR PDFF was 8.9 (4.6-17.1); 40, 38, 8, and 14% had grade zero, one, two, and three steatosis, respectively. Mean LFF increased slightly between baseline and follow-up scans: 2.22% MVC, 1.26% MET, 0.81% MVC+MET, and 1.39% ART alone. Prolonged intervention exposure (delayed week-48 scans) exhibited greater increases in MR PDFF (estimated difference 4.23% [95% confidence interval, 95% CI 2.97-5.48], P â<â0.001). There were no differences in predicted change for any intervention compared to ART alone: MVC (-0.42% [95% CI -1.53 to 0.68, P â=â0.45]), MET (-0.62 [-1.81 to 0.56, P â=â0.30]), and MVC+MET (-1.04 [-2.74 to 0.65, P â=â0.23]). Steatosis grade remained unchanged in 55% and increased in 24%. CONCLUSION: Baseline levels of liver fat were lower than predicted. Contrary to our hypothesis, neither MVC, MET, or the combination significantly reduced liver fat as measured by MRPDFF compared to ART alone.

BACKGROUND: People living with human immunodeficiency virus (HIV) are disproportionately impacted by socioeconomic deprivation and are at increased risk of developing other long-term conditions (LTCs). These illnesses require transformative action to tackle the adverse effects on their health. Data on lived experiences of LTCs among people living with HIV of Black African and Black Caribbean ethnicities are sparse, and how people with LTCs are impacted by social determinants of health (SDoH). METHODS: Through a phenomenological study design this qualitative study, conducted in 2022, comprised four focus group discussions (FGDs) with 20 people of Black ethnicities living with HIV were purposively invited from a community organisation (CO) in London, including four semistructured interviews with CO staff. Following transcription, qualitative data were analysed thematically and measures to validate the findings were implemented. RESULTS: The findings are presented in terms of the following four levels of SDoH: (1) individual determinants (such as the impact of SDoH on lifestyle modification and self-management); (2) interpersonal determinants (such as positive experiences of accessing healthcare for LTCs); (3) clinical determinants (such as care pathway barriers) and (4) systemic determinants (such as systemic barriers related to race/ethnicity). CONCLUSIONS: It is necessary to provide ongoing and interactive education to community members who live with HIV, focusing on risks and management of LTCs. Additionally, individuals would benefit from support to navigate increasingly complex and fragmented health services. Health Service staff require cultural competence when caring for patients of Black African and Black Caribbean ethnicities with complex health and psychosocial needs. PATIENT OR PUBLIC CONTRIBUTION: The research team collaborated with an HIV CO in South London from the very start of the project to agree the study design and learn about the realities of their daily lived experiences. Community collaborators helped to develop the semistructured interview and FGD topic guides, and were directly involved in the data gathering, analysis and validation.

OBJECTIVES: To describe HIV care outcomes in people of Black ethnicities living in England during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; coronavirus disease 2019 [COVID-19]) pandemic. METHODS: This was an observational cohort study of people of self-reported Black ethnicities attending for HIV care at nine HIV clinics across England. The primary outcome was a composite of antiretroviral therapy (ART) interruption and HIV viraemia (HIV RNA ≥200 copies/mL) ascertained via self-completed questionnaires and review of medical records. We used multivariable logistic regression to explore associations between ART interruption/HIV viraemia and demographic factors, pre-pandemic HIV immunovirological control, comorbidity status, and COVID-19 disease and vaccination status. RESULTS: We included 2290 people (median age 49.3 years; 56% female; median CD4 cell count 555 cells/mm3; 92% pre-pandemic HIV RNA <200 copies/mL), of whom 302 (13%) reported one or more ART interruption, 312 (14%) had documented HIV viraemia ≥200 copies/mL, and 401 (18%) experienced the composite endpoint of ART interruption/HIV viraemia. In multivariable analysis, a pre-pandemic HIV RNA <200 copies/mL (odds ratio [OR] 0.21; 95% confidence interval [CI] 0.15-0.30) and being vaccinated against SARS-CoV-2 (OR 0.41; 95% CI 0.30-0.55) were associated with reduced odds of ART interruption/HIV viraemia; pandemic-related disruptions to HIV care were common self-reported additional factors. CONCLUSIONS: During the COVID-19 pandemic, one in six people of Black ethnicities in this HIV cohort experienced an ART interruption/HIV viraemia. Some of these episodes resulted from pandemic-related healthcare disruptions. Associations with suboptimal engagement in HIV care pre-pandemic and not being vaccinated against SARS-CoV-2 suggest that wider health beliefs and/or poor healthcare access may have been contributory factors.

BACKGROUND: The combination of dolutegravir plus rilpivirine has been studied in people with virologically suppressed HIV with no previous history of treatment failure or resistance. We investigated the potential to maintain viral suppression with dolutegravir plus rilpivirine in people with Lys103Asn mutations whose HIV was previously managed with other treatment regimens. METHODS: In this open-label pilot trial at 32 clinical sites in seven European countries, virologically suppressed, HBsAg-negative adults aged 18 years or older with HIV-1 and Lys103Asn mutations were randomly assigned (2:1) to switch to 50 mg dolutegravir plus 25 mg rilpivirine (given as a single tablet) once daily or to continue their current antiretroviral therapy regimen (control group). After 48 weeks, participants in the control group also switched to dolutegravir plus rilpivirine. Randomisation was stratified by country, and a computer-generated randomisation list with permuted blocks within strata was used to assign participants to treatment groups. The primary endpoints were virological failure (ie, two consecutive measurements of 50 copies or more of HIV RNA per mL at least 2 weeks apart) and virological suppression (the proportion of participants with fewer than 50 copies of HIV RNA per mL) at week 48 (week 96 data will be reported separately). Analyses were done in the modified intention-to-treat population, which included all participants who received at least one dose of the study medication. This trial is registered with ClinicalTrials.gov, NCT05349838, and EudraCT, 2017-004040-38. FINDINGS: Between Nov 5, 2018, and Dec 9, 2020, 140 participants were enrolled and randomly assigned, 95 to the dolutegravir plus rilpivirine group and 45 to the control group. Virological failure was recorded in three participants (3·2%, 95% CI 0·7 to 9·0) in the the dolutegravir plus rilpivirine group and one (2·2%, 0·1 to 11·8) in the control group. The proportion of participants in whom virological suppression was maintained at week 48 was 88·4% (80·2 to 94·1) in the dolutegravir plus rilpivirine group versus 88·9% (75·9 to 96·3) in the control group (difference -0·5, -11·7 to 10·7). Significantly more adverse events were recorded in the dolutegravir plus rilpivirine group than in the control group (234 vs 72; p=0·0034), but the proportion of participants who reported at least one adverse event was similar between groups (76 [80%] of 95 vs 33 [73%] of 45; p=0·39). The frequency of serious adverse events was low and similar between groups. INTERPRETATION: Virological suppression was maintained at week 48 in most participants with Lys103Asn mutations when they switched from standard regimens to dolutegravir plus rilpivirine. The results of this pilot study, if maintained when the week 96 data are reported, support conduct of a large, well-powered trial of dolutegravir plus rilpivirine. FUNDING: ViiV Healthcare.

BACKGROUND: There are no validated waist circumference (WC) cut-offs to define metabolic syndrome in Black people with HIV. METHODS: Cross-sectional analyses within the CKD-AFRICA study. We used Pearson correlation coefficients and receiver operating characteristic (ROC) curves to describe the relationship between WC and cardiometabolic parameters including triglycerides, cholesterol, glucose, glycated haemoglobin (HbA1c), and homeostatic model assessment for insulin resistance (HOMA-IR), and to identify optimal WC cut-offs for each of these outcomes. RESULTS: We included 383 participants (55% female, median age 52 years) with generally well controlled HIV. Female and male participants had similar WC (median 98 vs. 97 cm, p = .16). Generally weak correlations (r2 < 0.2) between WC and other cardiometabolic parameters were observed, with low (<0.7) areas under the ROC curves. The optimal WC cut-offs for constituents of the metabolic syndrome, HbA1c and HOMA-IR ranged from 92 to 101 cm in women and 89-98 cm in men, respectively; these cut-offs had variable sensitivity (52%-100%) and generally poor specificity (28%-72%). CONCLUSIONS: In this cohort of Black people with HIV, WC cut-offs for cardiometabolic risk factors in male participants were in line with the recommended value of 94 cm while in female participants they vastly exceeded the recommended 80 cm for white women.

AIMS: Dolutegravir increases serum creatinine by inhibiting its renal tubular secretion and elimination. We investigated determinants of early changes in serum creatinine in a southern African cohort starting first-line dolutegravir-based antiretroviral therapy (ART). METHODS: We conducted a secondary analysis of data from participants in a randomized controlled trial of dolutegravir, emtricitabine and tenofovir disoproxil fumarate (TDF) or tenofovir alafenamide fumarate (TAF) (ADVANCE, NCT03122262). We assessed clinical, pharmacokinetic and genetic factors associated with change in serum creatinine from baseline to Week 4 using linear regression models adjusted for age, sex, baseline serum creatinine, HIV-1 RNA concentration, CD4 T-cell count, total body weight and co-trimoxazole use. RESULTS: We included 689 participants, of whom 470 had pharmacokinetic data and 315 had genetic data. Mean change in serum creatinine was 11.3 (SD 9.9) µmol.L-1. Factors that were positively associated with change in serum creatinine at Week 4 were increased log dolutegravir area under the 24-h concentration-time curve (change in creatinine coefficient [ß] = 2.78 µmol.L-1 [95% confidence interval (CI) 0.54, 5.01]), TDF use (ß = 2.30 [0.53, 4.06]), male sex (ß = 5.20 [2.92, 7.48]), baseline serum creatinine (ß = -0.22 [-0.31, -0.12]) and UGT1A1 rs929596 AâG polymorphism with a dominant model (ß = -2.33 [-4.49, -0.17]). The latter did not withstand correction for multiple testing. CONCLUSIONS: Multiple clinical and pharmacokinetic factors were associated with early change in serum creatinine in individuals initiating dolutegravir-based ART. UGT1A1 polymorphisms may play a role, but further research on genetic determinants is needed.

OBJECTIVES: To describe the clinical epidemiology of COVID-19 in people of black ethnicity living with HIV in the UK. METHODS: We investigated the incidence and factors associated with COVID-19 in a previously established and well-characterized cohort of black people with HIV. Primary outcomes were COVID-19 acquisition and severe COVID-19 disease (requiring hospitalization and/or resulting in death). Cumulative incidence was analysed using Nelson-Aalen methods, and associations between demographic, pre-pandemic immune-virological parameters, comorbidity status and (severe) COVID-19 were identified using Cox regression analysis. RESULTS: COVID-19 status was available for 1847 (74%) of 2495 COVID-AFRICA participants (median age 49.6 years; 56% female; median CD4 cell count = 555 cells/µL; 93% HIV RNA <200 copies/mL), 573 (31%) of whom reported at least one episode of COVID-19. The cumulative incidence rates of COVID-19 and severe COVID-19 were 31.0% and 3.4%, respectively. Region of ancestry (East/Southern/Central vs. West Africa), nadir CD4 count and kidney disease were associated with COVID-19 acquisition. Diabetes mellitus [adjusted hazard ratio (aHR) = 2.39, 95% confidence interval (CI): 1.26-4.53] and kidney disease (aHR = 2.53, 95% CI: 1.26-4.53) were associated with an increased risk, and recent CD4 count >500 cells/µL (aHR = 0.49, 95% CI: 0.25-0.93) with a lower risk of severe COVID-19. CONCLUSIONS: Region of ancestry was associated with COVID-19 acquisition, and immune and comorbidity statuses were associated with COVID-19 disease severity in people of black ethnicity living with HIV in the UK.

OBJECTIVE: Social determinants of health (SDH) are important determinants of long-term conditions and multimorbidity in the general population. The intersecting relationship between SDH and multimorbidity in people with HIV remains poorly studied. DESIGN: A cross-sectional study investigating the relationships between eight socio-economic parameters and prevalent comorbidities of clinical significance and multimorbidity in adults of African ancestry with HIV aged 18-65âyears in South London, UK. METHODS: Multivariable logistic regression analysis was used to evaluate associations between SDH and comorbidities and multimorbidity. RESULTS: Between September 2020 and January 2022, 398 participants (median age 52âyears, 55% women) were enrolled; 85% reported at least one SDH and 72% had at least one comorbidity. There were no associations between SDH and diabetes mellitus or kidney disease, few associations between SDH (job and food insecurity) and cardiovascular or lung disease, and multiple associations between SDH (financial, food, housing and job insecurity, low educational level, social isolation, and discrimination) and poor mental health or chronic pain. Associations between SDH and multimorbidity mirrored those for constituent comorbidities. CONCLUSION: We demonstrate strong associations between SDH and poor mental health, chronic pain and multimorbidity in people of black ethnicities living with HIV in the UK. These findings highlight the likely impact of enduring socioeconomic hardship in these communities and underlines the importance of holistic health and social care for people with HIV to address these adverse psychosocial conditions.
