- Abstract
Introduction: A substantial percentage of people with HIV are still admitted for care at advanced disease stages. Here, we investigate the availability of the supplies and infrastructure required to provide care for this population in healthcare facilities and explore correlations with local demand., Methods: AIDS Healthcare Foundation's partner facilities were invited to respond to a survey addressing the availability of services to support clients with advanced HIV. We present results per continent and according to gross national income per capita using frequencies and percentages. We generated country-level scores taking the average percentage of facilities with available resources on 10 key items and used Spearman's correlation to investigate relationships between country scores and local demand, depicted by the percentages of people with HIV newly enrolled in care with a CD4 T-cell count <200/mm
3 in 2022., Results: A total of 643 facilities from 37 countries responded to the survey between September and December 2021. Overall, services requiring more costly equipment and/or supplies were less frequently available. Facilities in Africa, Asia, and Latin America/Caribbean and those with lower gross national income had a somewhat lower availability of diagnostic and therapeutic resources. Availability of services was not correlated with local demand: 14 countries (42%) had scores below the 50% percentile despite having >20% of newly enrolled people with HIV with a CD4 T-cell count <200/mm3 ., Conclusion: Appropriate care can mitigate the morbidity and mortality associated with advanced HIV. We found that the healthcare services recommended by the World Health Organization as essential to support clients with advanced HIV are often unavailable in facilities providing HIV care, despite high local demand., (© 2024 The Author(s).

- Abstract
Introduction: Mutations associated with HIV drug resistance (DR) affect clinical outcomes. Understanding the prevalence of HIV DR and its association with viral suppression and survival in the paediatric population is key to inform patient care and health policies., Methods: We used Brazilian monitoring systems to identify genotyping tests performed in children living with HIV aged ≤18 months between 2009 and 2020. We categorized HIV DR using three criteria: any HIV DR (R
1 ), DR to nevirapine or efavirenz (R2 ), and DR to at least one antiretroviral recommended for children with HIV in Brazilian guidelines (R3 ). We investigated factors associated with HIV DR, viral suppression, and survival up to 3 years old using multivariable models. Lastly, we describe the annual prevalence of each type of HIV DR in Brazilian children with HIV between 2009 and 2020., Results: We included 1152 children with HIV with a median age of 5 months at genotype testing; 57% were females. R1 was observed in 30%, R2 in 17%, and R3 in 21%. Children with HIV whose birth parents were exposed to nevirapine or efavirenz before delivery had higher odds of R2 (odds ratio 3.4; 95% confidence interval [CI] 1.1-10.8). Children with HIV with R1 or R3 had higher rates of death than those with HIV with no HIV DR in the adjusted models (adjusted hazard ratios 4.7 [95% CI 1.6-13.9] and 4.1 [95% CI 1.4-12.4], respectively). The prevalence of resistance to nevirapine and efavirenz peaked in 2015. Over time, the prevalence of genotyping tests with no detected resistance varied between 57% and 87%., Conclusion: HIV DR is highly prevalent in children with HIV and is associated with lower survival., (© 2024 British HIV Association.)- Published

- Abstract
Introduction: The impact of specific policies on HIV care has been scarcely investigated. In this study we aimed to analyze the impact of the Treatment For All policy (TFA-2013) and the adoption of integrase strand transfer inhibitors (INSTIs-2017) as first-line therapy on clinical indicators of people living with HIV (PLHIV) in Brazil., Methods: We assessed the public database of Brazil's Ministry of Health and extracted data from 2009 to 2019. We investigated the impact of TFA and INSTIs with a time-series analysis of four health indicators in PLHIV: antiretroviral treatment (ART) initiation with a CD4+ count >500/mm
3 ; ART initiation <1 month after the first CD4+ measurement; viral load suppression (VLS); and treatment adherence. We explored trends over time by gender, age, macroregion of residency and municipal-level social vulnerability index., Results: We included 753 316 PLHIV in 2019. Most were males (64.81%) in the 30-49 years age category (50.86%). We observed an overall improvement in all HIV clinical indicators, with notable impact of TFA on timely ART initiation and VLS, and mild impact of INSTIs on treatment adherence. Such improvements were heterogeneous, with remarkable gaps in gender, age and socioeconomic groups that have persisted over time. Indicators point to inferior outcomes among children, older adults, women and people living in socially vulnerable locations., Conclusions: Recent Brazilian public policies have had positive impacts on key HIV clinical indicators. However, our results highlight the need for specific policies to improve HIV care for children, older adults, women and socially vulnerable groups., (© 2023 British HIV Association.)- Published

- Abstract
Introduction: Paediatric HIV follow-up is challenging, and treatment indicators are markedly far from Joint United Nations Programme on HIV/AIDS (UNAIDS) goals. In this study, we describe the 2019 Brazilian HIV cascade according to age categories and sociodemographic variables and address temporal trends between 2009 and 2019., Methods: We obtained data from the Brazilian Ministry of Health monitoring database. Cascade outcomes included retention in care, antiretroviral use, and viral suppression. We assessed the effect of age on timely initiation of antiretroviral treatment (ART; initiation with CD4
+ T-cell count ≥350 cells/mm3 or a first ART dispensation ≤30 days after the first CD4+ T-cell measurement) and detectable HIV viral load (>50 copies/mL) in univariable and multivariable analysis adjusted for sex, race, and social vulnerability index (SVI). Temporal trends in timely ART initiation and viral suppression were evaluated graphically., Results: Among 771 774 people living with HIV, those in the youngest age categories had poorer indicators in the care cascade. Those in younger age groups, those with higher SVI, and those declaring Black and native Brazilian race/ethnicity had higher odds of having detectable viral load and delayed ART initiation. Although children living with HIV tend to start ART with higher CD4+ T-cell counts, time-series analysis suggests that improvements in treatment indicators seen in the adult population are not observed in the paediatric population., Conclusion: Our results highlight the challenges faced by children and adolescents living with HIV in achieving UNAIDS goals. Lower access to ART among children is a central barrier to improved paediatric care., (© 2022 British HIV Association.)- Published

- Abstract
Objective: Our objective was to describe and compare the occurrence of neurological outcomes and neurosyphilis in people living with HIV with incident syphilis and no neurological symptoms who underwent early screening for asymptomatic neurosyphilis (ANS) or regular clinical management without a lumbar puncture., Methods: This was a retrospective cohort study in a single referral centre of Sao Paulo, Brazil. Patients with incident syphilis diagnosed between January 2000 and August 2016 and meeting the adapted criteria for ANS investigation suggested by Marra et al. (CD4
+ T-cell counts ≤350 cells/mm³ and/or venereal disease research laboratory test results ≥1:16) were identified. Those with no neurological symptoms and immediately referred for lumbar puncture were categorized as group 1, and those not referred for cerebrospinal fluid collection were categorized as group 2. We compared the occurrence of neurological symptoms and neurosyphilis diagnoses between the groups using incidence rates and Kaplan-Meier curves., Results: We included 425 participants with a median follow-up of 6 years. The incidence rate of neurological symptoms was 36.5/1000 person-years in group 1 and 40.6/1000 person-years in group 2 (incidence rate ratio [IRR] 0.90; 95% confidence interval [CI] 0.57-1.39; p = 0.62). The incidence rate of neurosyphilis was 15.0 cases/1000 person-years in group 1 and 6.7 cases/1000 person-years in group 2 (IRR 2.26; 95% CI 0.93-5.68; p = 0.05)., Conclusions: We found no statistically significant differences between groups in the incidence rates of neurological symptoms and neurosyphilis. Our findings support the current guidelines, which suggest a less invasive approach regarding ANS investigation among people living with HIV with incident syphilis., (© 2022 British HIV Association.)- Published

- Abstract
Introduction: HIV is still a central public health issue in Latin America, disproportionally affecting key populations. Knowledge and access to biomedical prevention strategies, including treatment as prevention (TASP) or undetectable = untransmissible (U=U), pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), are the first steps to increasing uptake. We used data from the Latin American MSM Internet Survey (LAMIS) to describe knowledge and access to biomedical HIV prevention strategies among gay, bisexual, transgender and other men who have sex with men (MSM) living in 18 Latin American countries., Methods: We compared LAMIS data across countries and according to age categories using frequencies and percentages. We also used multivariable models to explore whether age, gender identity, sexual identity, steady partnership, HIV status and education were independently associated with outcomes., Results: In all, 55 924 participants were included. Most were cisgender (99%) and identified as gay/homosexual (77%) or bisexual (17%). Schooling levels were very high, with 89% reporting highest attained education as tertiary level, university or post-graduation. In total, 16% had been previously diagnosed with HIV; of those, rates of undetectable viral load varied from 60% in Venezuela to 83% in Brazil. Overall, 54%, 54% and 52% of participants already knew about PEP, PrEP and U=U, respectively. Participants from Brazil and those aged between 26 and 55 years, living with diagnosed HIV and having a gay/homosexual identity had greater levels of awareness about biomedical prevention strategies., Conclusions: Our study highlights gaps in HIV prevention campaigns directed to MSM in Latin America resulting in low uptake of biomedical prevention methods., (© 2022 British HIV Association.)

- Abstract
Objectives: HIV self-testing is an effective tool to improve diagnostic coverage in key populations, enabling linkage to care and access to antiretroviral therapy. Its implementation requires better understanding of patients' perspectives on this novel strategy. The aim of the study was to investigate the perception of men who have sex with men (MSM) regarding the HIV oral fluid self-test (HIVST) in São Paulo, Brazil, and to analyse the sociodemographic characteristics and testing strategy preferences of individuals registered to undertake HIVST., Methods: Preceding the implementation of HIVST use as public policy in 2019, we recruited MSM living in São Paulo to undertake HIVST using a digital platform, and investigated their sociodemographic profiles, testing experiences and testing preferences. Results were compared according to reported lifetime HIV testing., Results: A total of 6477 MSM (median age 28 years) were recruited to the study from April 9th to December 31st, 2018. Seventy-eight per cent reported previous HIV testing. The opening hours of health facilities (53%), concern about disclosing intimate personal information to health care providers (34%) and fear of stigma (21%) were reported as the main barriers to testing. Older age, higher education, illicit drug use and self-identifying as gay were associated with prior HIV testing (P < 0.001). Most participants (67%) were unaware that HIVST was available before enrolling in the study. Preference for HIVST over other testing technologies was higher among those never tested (71%) than among participants with previous HIV testing (61%; P < 0.001)., Conclusions: HIVST was found to be an effective tool to improve testing uptake among MSM, particularly those who had never been tested before. Characterization of the most likely users of HIVST among MSM will help to inform implementation and scaling up of this novel testing method in the Brazilian public health system., (© 2021 British HIV Association.)

- Abstract
Objectives: The coronavirus disease (COVID-19) pandemic has been associated with severe disruptions in health care services, and nonpharmacological measures such as social distancing also have an impact on access to screening tests and on the long-term care of patients with chronic conditions globally. We aimed to describe the impact of the COVID-19 pandemic on HIV testing and treatment and to describe strategies employed to mitigate the impact of COVID-19 on HIV care., Methods: In this retrospective cohort study, we used secondary data from the AIDS Healthcare Foundation (AHF) Global Quality Program from 44 countries in four continents (Asia, Latin America and the Caribbean, Europe and Africa), and compared information on HIV testing, percentage of positive results, number of in-person appointments, and number of new enrolments in HIV care from 1 January 2020 to 31 August 2020 with the equivalent period in 2019., Results: Despite marked inter-country heterogeneities, we found that COVID-19 was associated with a significant reduction in HIV testing, an increase in the percentage of positive tests, a reduction in the number of in-person consultations and a reduction in the number of new enrolments in care, despite the implementation of several mitigation strategies. The impact of COVID-19 differed across continents and key populations., Conclusions: Our findings suggest that, in the years to come, health care services must be prepared to respond to the impact of COVID-19 on HIV testing and care. Providers and facilities should build on the lessons learned so far to further improve mitigation strategies and establish care priorities for both the pandemic and the post-pandemic periods., (© 2021 The Authors.
