RESUMEN

BACKGROUND: Weight gain following initiation of antiretroviral therapy (ART) is common. We assessed the impact of changes in weight in the year following ART initiation with subsequent cardiometabolic disease among AIDS Clinical Trials Group (ACTG) participants. METHODS: Linear regression models were fit to examine the association between change in weight/waist circumference (WC) in weeks 0-48 and change in metabolic parameters in weeks 0-48 and 48-96. Cox proportional hazard models were fit to examine the association between changes in weight/WC in weeks 0-48 and diabetes mellitus (DM), metabolic syndrome, or cardiometabolic and cardiovascular events after week 48. RESULTS: Participants (N = 2624) were primarily male (81%) and non-White (60%). Mean weight gain from 0-48 weeks was 3.6 kg (SD 7.3); 130 participants developed DM; 360 metabolic syndrome; 424 any cardiometabolic event; 28 any cardiovascular event, over 480 weeks of follow-up. In adjusted models, total cholesterol increased by 0.63 mg/dL (95% confidence interval [CI] [.38, .089]) and LDL by 0.39 mg/dL (0.19, 0.59) per 1 kg increase in weight from weeks 0 to48. Participants who experienced >10% weight gain (vs -5% to 5%) had an increased risk of DM (hazard ratio [HR] 2.01, 95% CI [1.30, 3.08]), metabolic syndrome (HR 2.24, 95% CI [1.55, 2.62]), and cardiometabolic outcomes (HR 1.54, 95% CI [1.22, 1.95]). Participants who lost more than 5% of their baseline weight had a lower risk of incident metabolic syndrome (HR 0.67, 95% CI [0.42, 1.07]). Trends for WC were similar. CONCLUSIONS: Weight and body composition changes in the first year following ART initiation are associated with contemporaneous changes in metabolic parameters and subsequent cardiometabolic disease.

RESUMEN

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.

RESUMEN

Globally, Botswana has one of the highest burdens of HIV. This study estimated the impact of the COVID-19 pandemic on the HIV cascade of care in Sub-Saharan Africa. We conducted an interrupted time series analysis on national-level data to estimate the effect of COVID-19 on the numbers of HIV tests, positive HIV tests and ART initiations from April 2019 until March 2021. In multivariable Poisson interrupted time series regression, the COVID-19 lockdown was associated with a 27% decrease in the monthly numbers of HIV tests (IRR 0.73, 95%CI 0.72-0.73), a 25% decrease in HIV positive tests (IRR 0.75, 95%CI 0.71-0.79), and a 43% reduction in ART initiations (IRR 0.57, 95%CI 0.55-0.60). The impact of the pandemic on all three outcomes was worse in males and those aged ≥ 50 years. In conclusion, COVID-19 had a strong negative impact on HIV screening, diagnosis and ART initiation in Botswana.

RESUMEN

Targeted strategies are central to increasing HIV-status awareness and progress on the care cascade among men. We implemented Village-Health-Team (VHT)-delivered HIV self-testing (HIVST) among men in a peri-urban Ugandan district and assessed linkage to confirmatory-testing, antiretroviral-therapy (ART) initiation and HIV-status disclosure following HIVST. We conducted a prospective cohort study from November 2018 to June 2019 and enrolled 1628 men from 30-villages of Mpigi district. VHTs offered each participant one HIVST-kit and a linkage-to-care information leaflet. At baseline, we collected data on demographics, testing history and risk behavior. At one-month, we measured linkage to confirmatory-testing and HIV-status disclosure, and at three months ART-initiation if tested HIV-positive. We used Poisson regression generalized estimating equations to evaluate predictors of confirmatory-testing. We found that 19.8% had never tested for HIV and 43% had not tested in the last 12-months. After receiving HIVST-kits, 98.5% self-reported HIVST-uptake in 10-days, 78.8% obtained facility-based confirmation in 30-days of HIVST with 3.9% tested HIV-positive. Of the positives, 78.8% were newly diagnosed, 88% initiated ART and 57% disclosed their HIV-status to significant others. Confirmatory testing was associated with having a higher level of education and knowing a partner's HIV-status. VHT-delivered HIVST may be effective for boosting testing, ART-initiation and HIV-status disclosure among men.

RESUMEN

BACKGROUND: Antiretroviral Therapy (ART) is pivotal in extending the lives of people living with HIV (PLWH) and minimizing transmission. Rapid ART initiation, defined as commencing ART within seven days of HIV diagnosis, is recommended for all PLWH. METHOD: A retrospective cohort study was conducted using data from the China Information System for Disease Control and Prevention. This study included PLWH diagnosed between January 2018 and December 2021 and treated by December 2022. Factors influencing rapid ART initiation were examined using univariate and multivariate Cox regression analyses. RESULTS: The study analyzed 1310 cases. The majority were male (77.4%), over 50 years old (46.7%), and contracted HIV through heterosexual transmission (70.0%). Rapid ART initiation was observed in 36.6% (n = 479) of cases, with a cumulative treatment rate of 72.9% within 30 days post-diagnosis. Heterosexual contact was associated with longer intervals from diagnosis to treatment initiation compared to homosexual contact (Adjusted Hazard Ratio (HR) = 0.813, 95% Confidence Interval (CI): 0.668-0.988). Individuals older than 50 years (Adjusted HR = 1.852, 95%CI: 1.149-2.985) were more likely to initiate ART rapidly. Conversely, treatment at the Second Public Hospital (Adjusted HR = 0.483, 95% CI: 0.330-0.708) and a CD4 cell counts above 500 (Adjusted HR = 0.553, 95% CI: 0.332-0.921) were associated with a lower likelihood of initiating treatment within seven days. CONCLUSIONS: A higher CD4 cell counts and receiving care in local public hospitals may deter rapid ART initiation. Providing CD4 counts results at diagnosis and offering testing and treatment in the same facility could enhance the rate of rapid ART initiation.

RESUMEN

Research suggests that women's experience of intimate partner violence (IPV) is associated with poor engagement in HIV care and treatment. However, most studies have been cross-sectional and conducted in North America. We examined the association between physical IPV and HIV care outcomes in a prospective cohort study of women living with HIV (WLHIV) in Malawi, South Africa, Uganda, and Zimbabwe. At enrollment, 15% of the 351 participants self-reported physical IPV. IPV experience was not associated with time to first engagement in HIV care or the proportion virally suppressed after 6 months on ART. Women reporting physical IPV were less likely to initiate ART within 6 months of becoming eligible (adjusted RR 0.74, 95% CI 0.53-1.03). IPV screening is critical to identify survivors and link them to appropriate services. However, addressing IPV may not increase engagement in HIV care or viral load suppression among WLHIV in sub-Saharan Africa.

RESUMEN

The Ending the HIV Epidemic initiative aims to decrease new HIV infections and promote test-and-treat strategies. Our aims were to establish a baseline of HIV outcomes among newly diagnosed PWH in Washington, DC (DC), a 'hotspot' for the HIV epidemic. We also examined sociodemographic and clinical factors associated with retention in care (RIC), antiretroviral therapy (ART) initiation and viral suppression (VS) among newly diagnosed PWH in the DC Cohort from 2011-2016. Among 455 newly diagnosed participants, 92% were RIC at 12 months, ART was initiated in 65% at 3 months and 91% at 12 months, VS in at least 17% at 3 months and 82% at 12 months and 55% of those with VS at 12 months had sustained VS for an additional 12 months. AIDS diagnosis was associated with RIC (aOR 2.99; 1.13-2.28), ART initiation by 3 months (aOR 2.58; 1.61-4.12) and VS by 12 months (aOR4.87; 1.69-14.03). This analysis contributes to our understanding of the HIV treatment dynamics of persons with recently diagnosed HIV infection in a city with a severe HIV epidemic.

RESUMEN

BACKGROUND: Women who are newly diagnosed with HIV infection during pregnancy may not be ready to immediately initiate lifelong antiretroviral therapy (ART; called Option B +) as is recommended. Lack of "readiness" drives early disengagement from care and undermines prevention of HIV transmission to infants. Several studies have shown high early attrition of women initiating ART in pregnancy. Although poor ART uptake and adherence have been attributed to various factors including stigma, disclosure issues and structural issues, there is no standard way of determining which pregnant woman will face challenges and therefore need additional support. We developed and validated a novel ART readiness tool in Lusaka, Zambia. METHODS: The aim of this study was to develop and validate a tool that could be used to assess how ready a newly diagnosed pregnant woman living with HIV would be to initiate ART on the day of diagnosis. Using a mixed method design, we conducted this study in three public-setting health facilities in Lusaka, Zambia. Informed by qualitative research and literature review, we identified 27 candidate items. We assessed content validity using expert and target population judgment approaches. We administered the 27-item questionnaire to 454 newly diagnosed pregnant women living with HIV, who were enrolled into a randomized trial (trials number NCT02459678). We performed item reduction analysis and used Cronbach's alpha coefficient of 0.70 as threshold for reliability. RESULTS: A total of 454 pregnant women living with HIV enrolled in the study between March 2017 and December 2017; 452 had complete data for analysis. The correlation coefficient between the 27 items on the completed ART readiness scale ranged from 0.31 to 0.70 while item discrimination index ranged from -0.01 to 2.38. Sixteen items were selected for the final scale, representing three domains, which we classified as "internalized and anticipated HIV stigma", "partner support" and "anticipated structural barriers". CONCLUSION: We developed and validated a tool that could be used to assess readiness of newly diagnosed women living with HIV to initiate ART. This ART readiness tool could allow clinics to tailor limited resources to pregnant women living with HIV needing additional support to initiate and remain on ART.

RESUMEN

BACKGROUND: Few studies have longitudinally assessed psychological distress among people with HIV (PWH) initiating ART in resource-limited settings. METHOD: Baseline, 6-month, and 12-month psychological distress were measured in a Nigerian cohort newly initiating therapy; the relationship between baseline factors and psychological distress at 12 months was assessed; and the association between psychological distress at 12 months and care retention or immunologic failure was determined. RESULTS: Among 563 patients, median age was 38 years (IQR: 33-46 years), 62% were female, and 51% were married. Psychological distress increased from 3% at baseline to 34% at 12 months. Age (aOR 1.28, 95% CI 1.06-1.56), female sex (aOR 2.89, 95% CI 1.93-4.33), lack of disclosure (aOR 4.32, 95% CI 2.48-7.51), and time on ART (6 months [aOR 6.91, 95% CI 3.14-15.18] and 12 months [aOR 32.63, 95% CI 16.54-64.36]) were associated with psychological distress while being married (OR 0.42, 95% CI 0.30-0.61) was associated with reduced odds. Tweve-month psychological distress was associated with increased risk of immunologic failure (aOR 2.22, 95% CI 1.31-3.82). CONCLUSION: The risk of psychological distress increased 30-fold in the first year on therapy in PWH in Nigeria.

RESUMEN

BACKGROUND: Same-day initiation (SDI) of antiretroviral therapy (ART) increases ART uptake, however retention in care after ART initiation remains a challenge. Public health behaviours, such as retention in HIV care and adherence to antiretroviral therapy (ART) pose major challenges to reducing new Human Immunodeficiency Virus (HIV) transmission and improving health outcomes among HIV patients. METHODS: We evaluated 6-month retention in care, and clinical outcomes of an ART cohort comprising of SDI and delayed ART initiators. We conducted a 6 months' observational prospective cohort study of 403 patients who had been initiated on ART. A structured questionnaire was used to abstract data from patient record review which comprised the medical charts, laboratory databases, and Three Interlinked Electronic Registers.Net (TIER.Net). Treatment adherence was ascertained by patient visit constancy for the clinic scheduled visit dates. Retention in care was determined by status at 6 months after ART initiation. RESULTS: Among the 403 participants enrolled in the study and followed up, 286 (70.97%) and 267 (66.25%) complied with scheduled clinics visits at 3 months and 6 months, respectively. One hundred and thirteen (28.04%) had been loss to follow-up. 17/403 (4.22%) had died and had been out of care after 6 months. 6 (1.49%) had been transferred to other health facilities and 113 (28.04%) had been loss to follow-up. Among those that had been lost to follow-up, 30 (33.63%) deferred SDI while 75 (66.37%) initiated ART under SDI. One hundred and eighty-nine (70.79%) participants who had remained in care were SDI patients while 78 (29.21%) were SDI deferred patients. In the bivariate analysis; gender (OR: 1.672; 95% CI: 1.002-2.791), number of sexual partners (OR: 2.092; 95% CI: 1.07-4.061), age (OR: 0.941; 95% CI: 0.734-2.791), ART start date (OR: 0.078; 95% CI: 0.042-0.141), partner HIV status (OR: 0.621; 95% CI: 0.387-0.995) and the number of hospitalizations after HIV diagnosis (OR: 0.173; 95% CI: 0.092-0.326). were significantly associated with viral load detection. Furthermore, SDI patients who defaulted treatment were 2.4 (95% CI: 1.165-4.928) times more likely to have increased viral load than those who had been returned in care. CONCLUSION: Viral suppression under SDI proved higher but with poor retention in care. However, the results also emphasise a vital need, to not only streamline processes to increase immediate ART uptake further, but also to ensure retention in care.

RESUMEN

OBJECTIVES: Although antiretroviral therapy (ART) has prolonged the lives of HIV-infected individuals, HIV reservoir remains the main stumbling block to HIV cure. Presently, early ART initiation is one of the effective measures to reduce the HIV reservoir. The effects of ART in Chinese individuals with acute and early HIV infection (AEHI) and chronic HIV infection (CHI) were analyzed in this study. METHODS: We performed virological and immunological parameter analysis in 29 AEHI and 19 CHI individuals who were initiated into ART in Beijing, China. The HIV DNA, CD4+ T-cell and CD8+ T-cell counts, and CD4/CD8 ratios between the two groups were compared using statistical analyses. RESULTS: At weeks 48 and 96, the total HIV DNA was significantly lower in the AEHI group than that the CHI group (2.48 [2.26-2.66] vs. 3.06 [2.79-3.33] log10 copies/106 peripheral blood mononuclear cells (PBMCs), p < 0.01 at week 48 and 2.17 [1.85-2.45] vs. 2.92 [2.73-3.24] log10 copies/106  PBMCs, p < 0.01 at week 96, respectively). The CD4/CD8 T-cell ratio in the AHI group at week 24 was significantly higher than that in the CHI group (0.71 [0.50-0.99] vs. 0.45 [0.34-0.65], p = 0.08). After 48 weeks of ART, there was still a negative correlation between the CD4/CD8 ratio and the HIV DNA level in the CHI group rather than the AEHI group. CONCLUSIONS: Early ART initiation could enhance an earlier immunological recovery in AEHI. Immunological normalization after ART initiation could provide important protection against the viral reservoir seeded in AEHI individuals.

RESUMEN

Timely uptake of Antiretroviral therapy considerably improves the health of people living with the Human Immunodeficiency virus. We conducted a cross-sectional study of newly HIV diagnosed individuals in four clinics in eThekwini municipality, KwaZulu-Natal. Data was collected between June 2020 and December 2020. Participants completed an interviewer-administered questionnaire after HIV testing, on the day of HIV diagnosis. We evaluated factors influencing uptake of same-day ART initiation in eThekwini clinics, KwaZulu Natal, South Africa. Demographic information, health status, sexual behaviour, knowledge of universal test and treat (UTT), ART initiation uptake, and disclosure data was collected. Among the 403 participants, same-day initiation (SDI) was 69.2% (n = 279). We observed the number of sexual partners (aOR 0.35; 95% CI 0.15-0.81), HIV status of the partner (aOR 5.03; 95% CI 2.74-9.26) and knowledge of UTT (aOR 1.97; 95% CI 1.34-2.90) were identified as major factors influencing uptake of same-day ART initiation. More strategies are needed to achieve the SDI uptake within the framework of UTT.

RESUMEN

In South Africa, where an estimated 34% of nearly 7-million HIV-positive people were not on antiretroviral therapy (ART) in 2019, innovative strategies to diagnose and link people to care are needed. HIV self-testing (HIVST) is one such strategy. However, there is concern that access to HIVST might result in re-testing among people on ART, with a risk of false negative results and disengagement from care. Between November 2017 and December 2018, HIVST kits were distributed at a private pharmacy and at HIV testing outreach events. Each participant was instructed to report their result via SMS and those who did not were followed-up telephonically 10 days later. Electronic medical records of participants were searched for evidence of HIV services 6 months before and after enrollment. Of 1482 participants, 163 (11%) were previously diagnosed HIV-positive prior to taking the test. Of these, 123 reported a result, however 87% reported a negative result. Of the 163 previously diagnosed, 84 were not in ART care prior to the test, with 15 (18%) linking to care post-test. Of 79 who were in ART care prior to the test, 76 (96%) remained in care, even though 51 (67%) had reported a negative result. Overall, 29% of participants reported their result via SMS, and 48% when telephoned. Despite efforts to dissuade them, some previously diagnosed HIV-positive utilised HIVST. For those disengaged from care this may facilitate re-engagement. Self-testing among those already in care, regardless of the reported result, did not disrupt their treatment, and their reasons for doing the test remain unclear.

RESUMEN

Current guidelines recommend starting antiretroviral therapy (ART) as soon as possible after HIV diagnosis to reduce morbidity, mortality and onward HIV transmission. We examined factors influencing ART initiation by women who seroconverted during the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial. ECHO, conducted between 2015 and 2018, enrolled HIV-negative, sexually active women, aged 16-35 years, from four African countries. Follow-up was 12-18 months, with quarterly HIV testing. Women with incident HIV infection received extensive counselling by trial staff and referral to local facilities for HIV care. Of 304 women with ≥90 days follow-up time since HIV diagnosis, 186(61.2%) initiated ART within 90 days, 69(22.7%) initiated after 90 days, and 49(16.1%) had not initiated by the end of the study. There were no statistically significant differences in characteristics among women who initiated ART ≤90 days versus those who did not. Frequent reasons for delayed or non-initiation of ART included not feeling ready to start ART and being newly diagnosed. In a large clinical trial, ART initiation was modest within 90 days of HIV diagnosis and grew to 84% with longer observation. Despite extensive counselling on the importance of early ART initiation, personal barriers delayed some women from starting ART.

RESUMEN

INTRODUCTION: In 2010, the Canadian province of British Columbia (BC) initiated the Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) program to improve HIV testing, linkage to care, and treatment uptake, thereby operationalizing the HIV Treatment as Prevention (TasP) framework at the population-level. In this analysis, we evaluated self-reported HIV care experiences and therapeutic outcomes among people diagnosed with HIV prior to and after implementation of this provincial program. METHODS: A cross-sectional analysis was performed on the baseline data of a cohort of people living with HIV (PLWH) (19 years and older) in the province of BC sampled from July 2016 to September 2018. All participants consented to linking their survey data to the provincial HIV treatment registry. Individuals diagnosed with HIV from January 1 2000-December 31 2009 were classified as pre-intervention and those diagnosed January 1 2010-December 31 2018 as post-intervention cohorts. Bivariate analyses were run using Chi-square and Wilcoxon Rank Sum tests. Cox proportional hazards regression model demonstrates time to antiretroviral therapy (ART) initiation (from HIV baseline) and virological suppression (2 consecutive plasma viral load measurements < 200 copies/ml). RESULTS: Of the 325 participants included in this analysis, 198 (61%) were diagnosed with HIV in the pre-intervention era and 127 (39%) in the post-intervention era. A higher proportion of participants in post-intervention era were diagnosed at walk-in clinics (45% vs. 39%) and hospitals (21% vs. 11%) (vs pre-intervention) (p = 0.042). Post-intervention participants had initiated ART with less advanced HIV disease (CD4 count 410 vs. 270 cells/ul; p = 0.001) and were less likely to experience treatment interruptions at any point in the 5 years after HIV diagnosis (17% vs. 48%; p < 0.001). The post-intervention cohort had significantly more timely ART initiation (aHR: 5.97, 95%CI 4.47, 7.97) and virologic suppression (aHR: 2.03, 95%CI 1.58, 2.60) following diagnosis, after controlling for confounders. CONCLUSIONS: We found favourable treatment experiences and more timely ART initiation and virologic suppression after a targeted TasP provincial program. Our results illustrate the importance of accessible low-barrier HIV testing and treatment in tackling the HIV epidemic.

RESUMEN

BACKGROUND: Successful linkage to HIV services and initiation of antiretroviral treatment (ART) for children living with HIV (CLHIV) is critical to improve pediatric ART coverage. We aimed to assess confirmatory testing, linkage, and rapid ART initiation among newly diagnosed CLHIV in Ethiopia from the perspectives of caregivers and healthcare workers (HCWs). METHODS: We conducted standardized surveys with HCWs and caregivers of children 2-14 years who were diagnosed with HIV but not yet on ART who had been identified during a cross-sectional study in Ethiopia from May 2017-March 2018. Eight health facilities based on their HIV caseload and testing volume and 21 extension sites were included. Forty-one children, 34 care givers and 40 healthcare workers were included in this study. Three months after study enrollment, caregivers were surveyed about timing and experiences with HIV service enrollment, confirmatory testing, and ART initiation. Data collected from HCWs included perceptions of confirmatory testing in CLHIV before ART initiation. SPSS was used to conduct descriptive statistics. RESULTS: The majority of the 41 CLHIV were enrolled to HIV services (n = 34, 83%) and initiated ART by three months (n = 32, 94%). Median time from diagnosis to ART initiation was 12 days (interquartile range 5-18). Five children died before the follow-up interview. Confirmatory HIV testing was conducted in 34 children and found no discordant results; the majority (n = 23, 68%) received it within one week of HIV diagnosis. Almost all HCWs (n = 39/40, 98%) and caregivers (n = 31/34, 91%) felt better/the same about test results after conducting confirmatory testing. CONCLUSION: Opportunities remain to strengthen linkage for newly diagnosed CLHIV in Ethiopia through intensifying early follow-up to ensure prompt confirmatory testing and rapid ART initiation. Additional services could help caregivers with decision-making around treatment initiation for their children.

RESUMEN

BACKGROUND: In response to the global pandemic of COVID-19, countries around the world began imposing stay-at-home orders, restrictions on transport, and closures of businesses in early 2020. South Africa implemented a strict lockdown in March 2020 before its first COVID-19 wave started, gradually lifted restrictions between May and September 2020, and then re-imposed restrictions in December 2020 in response to its second wave. There is concern that COVID-19-related morbidity and mortality, fear of transmission, and government responses may have led to a reduction in antiretroviral treatment (ART) initiations for HIV-infected individuals in countries like South Africa. METHODS: We analyzed national, public sector, facility-level data from South Africa's District Health Information System (DHIS) from January 2019 to March 2021 to quantify changes in ART initiation rates stratified by province, setting, facility size and type and compared the timing of these changes to COVID-19 case numbers and government lockdown levels. We excluded facilities with missing data, mobile clinics, and correctional facilities. We estimated the total number of ART initiations per study month for each stratum and compared monthly totals, by year. RESULTS: At the 2471 facilities in the final data set (59% of all ART sites in the DHIS), 28% fewer initiations occurred in 2020 than in 2019. Numbers of ART initiations declined sharply in all provinces in April-June 2020, compared to the same months in 2019, and remained low for the rest of 2020, with some recovery between COVID-19 waves in October 2020 and possible improvement beginning in March 2021. Percentage reductions were largest in district hospitals, larger facilities, and urban areas. After the initial decline in April-June 2020, most provinces experienced a clear inverse relationship between COVID-19 cases and ART initiations but little relationship between ART initiations and lockdown level. CONCLUSIONS: The COVID-19 pandemic and responses to it resulted in substantial declines in the number of HIV-infected individuals starting treatment in South Africa, with no recovery of numbers during 2020. These delays may lead to worse treatment outcomes for those with HIV and potentially higher HIV transmission. Exceptional effort will be needed to sustain gains in combatting HIV.

RESUMEN

BACKGROUND: Studies have demonstrated benefits of antiretroviral therapy (ART) initiation on the day of human immunodeficiency virus (HIV) testing or at first clinical visit. The hospital setting is understudied for immediate ART initiation. METHODS: CTN0049, a linkage-to-care randomized clinical trial, enrolled 801 persons living with HIV (PLWH) and substance use disorder (SUD) from 11 hospitals across the United States. This secondary analysis examined factors related to initiating (including reinitiating) ART in the hospital and its association with linkage to HIV care, frequency of outpatient care visits, retention, and viral suppression. RESULTS: Of 801 participants, 124 (15%) initiated ART in the hospital, with more than two-thirds of these participants (80/124) initiating ART for the first time. Time to first HIV care visit among those who initiated ART in the hospital and those who did not was 29 and 54 days, respectively (P = .0145). Hospital initiation of ART was associated with increased frequency of HIV outpatient care visits at 6 and 12 months. There was no association with ART initiation in the hospital and retention and viral suppression over a 12-month period. Participants recruited in Southern hospitals were less likely to initiate ART in the hospital (P < .001). CONCLUSIONS: Previous research demonstrated benefits of immediate ART initiation, yet this approach is not widely implemented. Research findings suggest that starting ART in the hospital is beneficial for increasing linkage to HIV care and frequency of visits for PLWH and SUD. Implementation research should address barriers to early ART initiation in the hospital.

RESUMEN

OBJECTIVES: People living with HIV (PLWH) have increased risk of chronic disease and poor mental health. We aimed to explore HIV disease indicators, comorbidity, and risk behavior of recent antiretroviral therapy (ART) initiators to inform current needs of PLWH. METHODS: Men who have sex with men (MSM) in the Multicenter AIDS Cohort Study (MACS) who initiated ART between 2010 and 2018 (recent initiators) were compared with age-, race- and geographic location-matched men who initiated ART during 2000-2009 (early initiators). Measures of HIV disease, behavior, comorbidity and mental health were collected prospectively every 6 months using standardized forms. RESULTS: Recent initiators had higher current CD4 (median CD4 451 vs. 307 cells/µL, P < 0.0001) and nadir CD4 (451 vs. 300 cells/µL, P < 0.0001) than earlier initiators. The proportion achieving viral suppression within a year of starting ART was significantly higher in recent compared with earlier initiators (92% vs. 74%, P < 0.0001). Median [interquartile range (IQR)] time from HIV diagnosis to ART initiation was 5.4 (1.7-23.1) months in recent initiators. Comorbidity prevalence was high in recent initiators, including obesity (24%), hypertension (25%) and kidney disease (15%). Substance use continues to be common, including cigarette use (40%), daily alcohol use (88%) and marijuana use (46%). CONCLUSIONS: Improvements in getting individuals onto ART at an early stage have led to substantially higher CD4 cell counts at initiation. However, the high burden of comorbidity, substance use and poor mental health affecting MSM living with HIV in the US underscore ongoing challenges and our need to adapt and coordinate care.

RESUMEN

Accurate reporting of antiretroviral therapy (ART) uptake is crucial for measuring the success of epidemic control. Programs without linked electronic medical records are susceptible to duplicating ART initiation events. We assessed the prevalence of undisclosed ART use at the time of treatment initiation and explored its correlates among people presenting to public ambulatory clinics in South Africa. Data were analyzed from the community-based delivery of ART (DO ART) clinical trial, which recruited people living with HIV who presented for ART initiation at two clinics in rural South Africa. We collected data on socioeconomic factors, clinical factors, and collected blood as part of study screening procedures. We estimated the proportion of individuals presenting for ART initiation with viral load suppression (< 20 copies/mL) and fitted regression models to identify social and clinical correlates of non-disclosure of ART use. We also explored clinical and national databases to identify records of ART use. Finally, to confirm surreptitious ART use, we measured tenofovir (TDF) and emtricitabine (FTC) levels in dried blood spots. A total of 193 people were screened at the two clinics. Approximately 60% (n = 114) were female, 40% (n = 78) reported a prior HIV test, 23% (n = 44) had disclosed to a partner, and 31% (n = 61) had a partner with HIV. We found that 32% (n = 62) of individuals presenting for ART initiation or re-initiation had an undetectable viral load. In multivariable regression models, female sex (AOR 2.16, 95% CI 1.08-4.30), having a prior HIV test and having disclosed their HIV status (AOR 2.48, 95% CI 1.13-5.46), and having a partner with HIV (AOR 1.94, 95% CI 0.95-3.96) were associated with having an undetectable viral load. In records we reviewed, we found evidence of ART use from either clinical or laboratory databases in 68% (42/62) and detected either TDF or FTC in 60% (37/62) of individuals with an undetectable viral load. Undisclosed ART use was present in approximately one in three individuals presenting for ART initiation or re-initiation at ambulatory HIV clinics in South Africa. These results have important implications for ART resource use and planning in the region. A better understanding of reasons for non-disclosure of ART at primary health care clinics in such settings is needed.
