The Impact of Same-Day Antiretroviral Therapy Initiation Under the World Health Organization Treat-All Policy

Changes in access to viral load testing, incidence rates of viral load suppression and rebound following the introduction of the 'universal test and treat' guidelines in Cameroon: A retrospective follow-up analysis

Cameroon adopted and started implementing in 2016, the 'universal test and treat' (UTT) guidelines to fast-track progress towards the 95-95-95 ambitious targets to end the HIV epidemic. Achieving the third 95 (viral load suppression) is the most desirable target in HIV care. We aimed to evaluate the effectiveness of this novel approach on access to viral load testing (VLT), viral suppression (VLS), and viral load rebound (VLR). A retrospective cohort study was conducted at The Nkongsamba Regional Hospital to compare VLT outcomes between the pre-UTT (2002 to 2015) and the post-UTT (2016 to 2020) periods. We used a data extraction form to collect routine data on adult patients living with HIV. We measured uptake levels of the first and serial VLT and compared the incidence rates of VLS (VL<1000 copies/ml) and viral load rebound (VLR) before and after introducing the UTT approach using Kaplan Meier plots and log-rank tests. Cox regression was used to screen for factors independently associated with VLS and VLR events between the guideline periods. Access to initial VLT increased significantly from 6.11% to 25.56% at 6 months and from 12.00% to 73.75% at 12 months before and after introducing the UTT guidelines respectively. After a total observation time at risk of 17001.63 person-months, the UTT group achieved an incidence rate of 90.36 VLS per 1000 person-months, four-fold higher than the 21.71 VLS per 1000 person-months observed in the pre-UTT group (p<0.0001). After adjusting for confounding, the VLS rate was about 6-fold higher in the UTT group than in the pre-UTT group (adjusted Hazard Rate (aHR) = 5.81 (95% confidence interval (95%CI): 4.43-7.60). The incidence of VLR increased from 12.60 (95%CI: 9.50-16.72) to 19.11 (95%CI: 14.22-25.67) per 1000 person-months before and after the introduction of UTT guidelines respectively. After adjusting, VLR was more than twice as high in the UTT group than in the pre-UTT group (aHR = 2.32, 95%CI: 1.30-4.13). Increased access to initial VLT and higher rates of VLS have been observed but there are concerns that the suppressed viral load may not be durable since the introduction of the UTT policy in this setting.

Long-term HIV care outcomes under universal HIV treatment guidelines: A retrospective cohort study in 25 countries

BACKGROUND

While national adoption of universal HIV treatment guidelines has led to improved, timely uptake of antiretroviral therapy (ART), longer-term care outcomes are understudied. There is little data from real-world service delivery settings on patient attrition, viral load (VL) monitoring, and viral suppression (VS) at 24 and 36 months after HIV treatment initiation.

METHODS AND FINDINGS

For this retrospective cohort analysis, we used observational data from 25 countries in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium's Asia-Pacific, Central Africa, East Africa, Central/South America, and North America regions for patients who were ART naïve and aged ≥15 years at care enrollment between 24 months before and 12 months after national adoption of universal treatment guidelines, occurring 2012 to 2018. We estimated crude cumulative incidence of loss-to-clinic (CI-LTC) at 12, 24, and 36 months after enrollment among patients enrolling in care before and after guideline adoption using competing risks regression. Guideline change-associated hazard ratios of LTC at each time point after enrollment were estimated via cause-specific Cox proportional hazards regression models. Modified Poisson regression was used to estimate relative risks of retention, VL monitoring, and VS at 12, 24, and 36 months after ART initiation. There were 66,963 patients enrolling in HIV care at 109 clinics with ≥12 months of follow-up time after enrollment (46,484 [69.4%] enrolling before guideline adoption and 20,479 [30.6%] enrolling afterwards). More than half (54.9%) were females, and median age was 34 years (interquartile range [IQR]: 27 to 43). Mean follow-up time was 51 months (standard deviation: 17 months; range: 12, 110 months). Among patients enrolling before guideline adoption, crude CI-LTC was 23.8% (95% confidence interval [95% CI] 23.4, 24.2) at 12 months, 31.0% (95% CI [30.6, 31.5]) at 24 months, and 37.2% (95% [CI 36.8, 37.7]) at 36 months after enrollment. Adjusting for sex, age group, enrollment CD4, clinic location and type, and country income level, enrolling in care and initiating ART after guideline adoption was associated with increased hazard of LTC at 12 months (adjusted hazard ratio [aHR] 1.25 [95% CI 1.08, 1.44]; p = 0.003); 24 months (aHR 1.38 [95% CI 1.19, 1.59]; p < .001); and 36 months (aHR 1.34 [95% CI 1.18, 1.53], p < .001) compared with enrollment before guideline adoption, with no before-after differences among patients with no record of ART initiation by end of follow-up. Among patients retained after ART initiation, VL monitoring was low, with marginal improvements associated with guideline adoption only at 12 months after ART initiation. Among those with VL monitoring, VS was high at each time point among patients enrolling before guideline adoption (86.0% to 88.8%) and afterwards (86.2% to 90.3%), with no substantive difference associated with guideline adoption. Study limitations include lags in and potential underascertainment of care outcomes in real-world service delivery data and potential lack of generalizability beyond IeDEA sites and regions included in this analysis.

CONCLUSIONS

In this study, adoption of universal HIV treatment guidelines was associated with lower retention after ART initiation out to 36 months of follow-up, with little change in VL monitoring or VS among retained patients. Monitoring long-term HIV care outcomes remains critical to identify and address causes of attrition and gaps in HIV care quality.

Comparable clinical outcomes with same-day versus rapid initiation of antiretroviral therapy in Taiwan

OBJECTIVES

WHO has recommended same-day antiretroviral therapy (SDART) initiation since 2017; however, higher attrition rates were noted in developing countries.

METHODS

We included newly diagnosed people with HIV (PWH) from 2018 to 2022 at 18 hospitals around Taiwan. SDART initiation was defined as starting ART on the same day of HIV diagnosis and rapid initiation as starting ART within 14 days of diagnosis. A composite unfavorable outcome was defined as death after 30 days of diagnosis, loss to follow-up (LTFU), or virologic failure or rebound at 12 months.

RESULTS

At 12 months, PWH on SDART initiation and those on rapid ART initiation showed similar rates of engagement in care with plasma HIV-1 RNA <50 copies/mL (87.5% vs 87.7%) and composite unfavorable outcome (7.7% vs 7.7%). PWH aged >30 years were less likely to have LTFU (aHR 0.44, 95% CI 0.28-0.70). PWH aged >30 years (aHR 0.59, 95% CI 0.41-0.85) and gay, bisexual, and men who have sex with men (GBMSM) (aHR 0.50, 95% CI 0.32-0.79) were less likely to have composite unfavorable outcomes.

CONCLUSIONS

SDART and rapid ART initiation resulted in comparable clinical outcomes and viral suppression rates. PWH aged >30 years and GBMSM were less likely to have unfavorable outcomes.

Same-day ART initiation, loss to follow-up and viral load suppression among people living with HIV in low- and middle-income countries: systematic review and meta-analysis

Introduction

in 2015, the World Health Organization recommended early antiretroviral therapy (ART) initiation after HIV diagnosis. Mixed results on the effect of same-day ART initiation (SDI) over non-same-day ART initiation (NSDI) on loss to follow-up (LTFU) and viral load suppression (VLS) necessitate further evaluation.

Methods

this was a systematic review and meta-analysis of people living with HIV in low- and middle-income countries (LMICs). Multiple databases were searched from January 2016 to December 2022. VLS was defined as HIV RNA <1,000 or <400 cells/ml, depending on the study. Forest plots were used to present the pooled prevalence and 95% confidence intervals (CIs). Heterogeneity was tested by an I2 statistic and a p-value of <0.05 indicated its presence. Analyses were performed in STATA.

Results

sixteen studies (5 clinical trials, 10 cohorts, and 1 cross-sectional) were included in the final analysis. Nine studies with 157,633 people living with HIV were analyzed for LTFU and the pooled prevalence of LTFU was 22.0% (95%CI; 18.5-25.7). The pooled prevalence of VLS was 72.7% (95%CI; 65.4-79.5%). The I2 statistic had a Q value of 200.62 (p<0.001) and 44.63 (p<0.001) for pooled prevalence of LTFU and VLS, respectively. Overall, compared to those who received NSDI, SDI had a significantly increased risk of LTFU (risk difference (RD)=0.04; 95%CI: 0.01-0.07). Although observational studies showed an increased risk of LTFU among SDI compared to NSDI (RD=0.05, 95%CI: 0.02-0.08), clinical trials did not. There was no statistically significant difference in VLS comparing those who received SDI vs NSDI (RD= 0.02, 95%CI: -0.03 - 0.07).

Conclusion

nearly two in ten people living with HIV in LMICs who initiated ART were LTFU. SDI was associated with increased risk of LTFU. Efforts to prevent LTFU among those who receive SDI are critical to maximize its potential benefits.

Interruptions in treatment among adults on anti-retroviral therapy before and after test-and-treat policy in Tanzania

INTRODUCTION

The World Health Organization recommended the initiation of antiretroviral therapy (ART) for people living with HIV (PLHIV) regardless of CD4 cell counts. Tanzania adopted this recommendation known as test-and-treat policy in 2016. However, programmatic implementation of this policy has not been assessed since its initiation. The objective of the study was to assess the impact of this policy in Tanzania.

METHODS

This was a cross-sectional study among PLHIV aged 15 years and older using routinely collected program data. The dependent variable was interruption in treatment (IIT), defined as no clinical contact for at least 90 days after the last clinical appointment. The main independent variable was test-and-treat policy status which categorized PLHIV into the before and after groups. Co-variates were age, sex, facility type, clinical stage, CD4 count, ART duration, and body mass index. The associations were assessed using the generalized estimating equation with inverse probability weighting.

RESULTS

The study involved 33,979 PLHIV-14,442 (42.5%) and 19,537 (57.5%) were in the before and after the policy groups, respectively. Among those who experienced IIT, 4,219 (29%) and 7,322 (38%) were in the before and after the policy groups respectively. Multivariable analysis showed PLHIV after the policy was instated had twice [AOR 2.03; 95%CI 1.74-2.38] the odds of experiencing IIT than those before the policy was adopted. Additionally, higher odds of experiencing IIT were observed among younger adults, males, and those with advanced HIV disease.

CONCLUSION

Demographic and clinical status variables were associated with IIT, as well as the test-and-treat policy. To achieve epidemic control, programmatic adjustments on continuity of treatment may are needed to complement the programmatic implementation of the policy.

Prevalence of delayed antiretroviral therapy initiation among people living with HIV: A systematic review and meta-analysis

OBJECTIVE

HIV continues to be a global challenge. Key recommendations for HIV prevention and treatment are presented on rapid antiretroviral therapy (ART) initiation. However, several studies showed a high prevalence of delayed ART initiation. The aim of this systematic review and meta-analysis was to assess the prevalence of delayed ART initiation among HIV-infected patients globally.

METHODS

This review summarised eligible studies conducted between January 2015 and August 2022 on the prevalence of delayed ART initiation in HIV-infected adults (age ≥ 15). Relevant studies were systematic searched through PubMed/Medline, EMBASE, Web of Science, China National Knowledge Infrastructure, Wanfang, and Chongqing VIP databases. Random-effects models were used to calculate pooled prevalence estimates. The heterogeneity was evaluated using Cochran's Q test and I2 statistics. Moreover, potential sources of heterogeneity were explored using univariate subgroup analysis.

RESULTS

Data on the prevalence of delayed ART initiation was pooled across 29 studies involving 34,937 participants from 15 countries. The overall pooled prevalence of delayed ART initiation was 36.1% [95% confidence interval (CI), 29.7-42.5%]. In subgroup analysis, the estimated pooled prevalence decreased with age. By sex, the prevalence was higher among male patients (39.3%, 95% CI: 32.2-46.4%) than female (36.5%, 95% CI: 26.9-50.7%). Patients with high CD4 cell count were more likely to delay ART initiation than those with low CD4 cell count (>500cells/mm3: 40.3%; 201-500cells/mm3: 33.4%; and ≤200cells/mm3: 25.3%).

CONCLUSIONS

Our systematic review and meta-analysis identified a high prevalence of delayed ART initiation. The prolonged time interval between diagnosis and treatment is a prevalent and unaddressed problem that should spur initiatives from countries globally. Further research is urgently needed to identify effective strategies for promoting the early ART initiation.

Treatment Outcomes After Offering Same-Day Initiation of Human Immunodeficiency Virus Treatment-How to Interpret Discrepancies Between Different Studies

The World Health Organization recommends same-day initiation of antiretroviral therapy (ART) for all persons diagnosed with HIV and ready to start treatment. Evidence, mainly from randomized trials, indicates offering same-day ART increases engagement in care and viral suppression during the first year. In contrast, most observational studies using routine data find same-day ART to be associated with lower engagement in care. We argue that this discrepancy is mainly driven by different time points of enrollment, leading to different denominators. While randomized trials enroll individuals when tested positive, most observational studies start at the time point when ART is initiated. Thus, most observational studies omit those who are lost between diagnosis and treatment, thereby introducing a selection bias in the group with delayed ART. This viewpoint article summarizes the available evidence and argues that the benefits of same-day ART outweigh a potential higher risk of attrition from care after ART initiation.

Application of targeted maximum likelihood estimation in public health and epidemiological studies: a systematic review

PURPOSE

The targeted maximum likelihood estimation (TMLE) statistical data analysis framework integrates machine learning, statistical theory, and statistical inference to provide a least biased, efficient, and robust strategy for estimation and inference of a variety of statistical and causal parameters. We describe and evaluate the epidemiological applications that have benefited from recent methodological developments.

METHODS

We conducted a systematic literature review in PubMed for articles that applied any form of TMLE in observational studies. We summarized the epidemiological discipline, geographical location, expertize of the authors, and TMLE methods over time. We used the Roadmap of Targeted Learning and Causal Inference to extract key methodological aspects of the publications. We showcase the contributions to the literature of these TMLE results.

RESULTS

Of the 89 publications included, 33% originated from the University of California at Berkeley, where the framework was first developed by Professor Mark van der Laan. By 2022, 59% of the publications originated from outside the United States and explored up to seven different epidemiological disciplines in 2021-2022. Double-robustness, bias reduction, and model misspecification were the main motivations that drew researchers toward the TMLE framework. Through time, a wide variety of methodological, tutorial, and software-specific articles were cited, owing to the constant growth of methodological developments around TMLE.

CONCLUSIONS

There is a clear dissemination trend of the TMLE framework to various epidemiological disciplines and to increasing numbers of geographical areas. The availability of R packages, publication of tutorial papers, and involvement of methodological experts in applied publications have contributed to an exponential increase in the number of studies that understood the benefits and adoption of TMLE.

Uptake of same-day initiation of HIV treatment in Malawi, South Africa, and Zambia as reported in routinely collected data: the SPRINT retrospective cohort study

Background: Since 2017 global guidelines have recommended "same-day initiation" (SDI) of antiretroviral treatment (ART) for patients considered ready for treatment on the day of HIV diagnosis. Many countries have incorporated a SDI option into national guidelines, but SDI uptake is not well documented. We estimated average time to ART initiation at 12 public healthcare facilities in Malawi, five in South Africa, and 12 in Zambia. Methods: We identified patients eligible to start ART between January 2018 and June 2019 from facility testing registers and reviewed their medical records from HIV diagnosis to the earlier date of treatment initiation or 6 months. We estimated the proportion of patients initiating ART on the same day or within 7, 14, 30, or 180 days of baseline. Results: We enrolled 825 patients in Malawi, 534 in South Africa, and 1,984 in Zambia. Overall, 88% of patients in Malawi, 57% in South Africa, and 91% in Zambia received SDI. In Malawi, most who did not receive SDI had not initiated ART ≤6 months. In South Africa, an additional 13% initiated ≤1 week, but 21% had no record of initiation ≤6 months. Among those who did initiate within 6 months in Zambia, most started ≤1 week. There were no major differences by sex. WHO Stage III/IV and tuberculosis symptoms were associated with delays in ART initiation;  clinic size and having a CD4 count done were associated with an increased likelihood of SDI. Conclusions: As of 2020, SDI of ART was widespread, if not nearly universal, in Malawi and Zambia but considerably less common in South Africa. Limitations of the study include pre-COVID-19 data that do not reflect pandemic adaptations and potentially missing data for Zambia. South Africa may be able to increase overall ART coverage by reducing numbers of patients who do not initiate ≤6 months.

Immediate ART and clinical outcomes in New York City among patients newly diagnosed with HIV

Immediate antiretroviral therapy (iART) has been shown to decrease time to viral suppression. Our center underwent significant practice transformation to support iART, including a same-day Open Access (OA) model and enhanced care coordination. We examined whether same-day ART at linkage was associated with favorable proximate and long-term HIV care outcomes. From 2018 to 2019, patients newly diagnosed with HIV, linked to care at our institution, and iART eligible were included. We evaluated the association between iART and time to viral suppression, and between iART and initial/sustained viral suppression and retention in care. We also evaluated the association between use of OA and frequency of care coordination with the same outcomes. Of the 107 patients included, 72 initiated same-day ART at linkage and 35 did not. There was no statistically significant differences in whether patients were ever suppressed, had sustained viral suppression, or were retained in care between those who received same-day ART and those who did not. More care coordination was associated with retention in care (RR 1.21 [1.01-1.5]; p = 0.05). Organizing vital services and ensuring implementation strategies that facilitate iART, while tailoring the approach to the patient's comfort level, is likely optimal for longitudinal HIV care engagement.

Association Between Time to Antiretroviral Therapy and Loss to Care Among Newly Diagnosed Rwandan People Living with Human Immunodeficiency Virus

Despite improved clinical outcomes of initiating antiretroviral therapy (ART) soon after diagnosis, conflicting evidence exists regarding the impact of same-day ART initiation on subsequent clinical outcomes. We aimed to characterize the associations of time to ART initiation with loss to care and viral suppression in a cohort of newly diagnosed people living with HIV (PLHIV) entering care after Rwanda implemented a national "Treat All" policy. We conducted a secondary analysis of routinely collected data of adult PLHIV enrolling in HIV care at 10 health facilities in Kigali, Rwanda. Time from enrollment to ART initiation was categorized as same day, 1-7 days, or >7 days. We examined associations between time to ART and loss to care (>120 days since last health facility visit) using Cox proportional hazards models, and between time to ART and viral suppression using logistic regression. Of 2,524 patients included in this analysis, 1,452 (57.5%) were women and the median age was 32 (interquartile range: 26-39). Loss to care was more frequent among patients who initiated ART on the same day (15.9%), compared with those initiating ART 1-7 days (12.3%) or >7 days (10.1%), p < .001. In multivariable analyses, same-day ART initiation was associated with a greater hazard of loss to care compared with initiating >7 days after enrollment (adjusted hazard ratio 1.39, 95% confidence interval: 1.04-1.85). A total of 1,698 (67.3%) had available data on viral load measured within 455 days after enrollment. Of these, 1,476 (87%) were virally suppressed. A higher proportion of patients initiating ART on the same day were virally suppressed (89%) compared with those initiating 1-7 days (84%) or >7 days (88%) after enrollment. This association was not statistically significant. Our findings suggest that ensuring adequate, early support for PLHIV initiating ART rapidly may be important to improve retention in care for newly diagnosed PLHIV in the era of Treat All.

Uptake of same-day initiation of HIV treatment among adult men and women in Malawi, South Africa, and Zambia: the SPRINT retrospective cohort study

Background: Since 2017 global guidelines have recommended "same-day initiation" (SDI) of antiretroviral treatment (ART) for patients considered ready for treatment on the day of HIV diagnosis. Many countries have incorporated a SDI option into national guidelines, but SDI uptake is not well documented. We estimated average time to ART initiation at 12 public healthcare facilities in Malawi, five in South Africa, and 12 in Zambia. Methods: We sequentially enrolled patients eligible to start ART between January 2018 and June 2019 and reviewed their medical records from the point of HIV diagnosis or first HIV-related interaction with the clinic to the earlier date of treatment initiation or 6 months. We estimated the proportion of patients initiating ART on the same day or within 7, 14, 30, or 180 days of baseline. Results: We enrolled 826 patients in Malawi, 534 in South Africa, and 1,984 in Zambia. Overall, 88% of patients in Malawi, 57% in South Africa, and 91% in Zambia were offered and accepted SDI. In Malawi, most who did not receive SDI had not initiated ART ≤6 months. In South Africa, an additional 13% initiated ≤1 week, but 21% had no record of initiation ≤6 months. Among those who did initiate within 6 months in Zambia, most started ≤1 week. There were no major differences by sex. WHO Stage III/IV and tuberculosis symptoms were associated with delays in ART initiation. Conclusions: As of 2020, SDI of ART was widespread, if not nearly universal, in Malawi and Zambia but considerably less common in South Africa. Limitations of the study include pre-COVID-19 data that do not reflect pandemic adaptations and potentially missing data for Zambia. South Africa may be able to increase overall ART coverage by reducing numbers of patients who do not initiate ≤6 months. Registration: Clinicaltrials.gov ( NCT04468399; NCT04170374; NCT04470011).

Same-Day ART Initiation and Associated Factors Among People Living with HIV on Lifelong Therapy at Nekemte Specialized Hospital, Western Ethiopia

Background

The test-and-treat approach recommends early ART initiation (same day). Early ART start has double the benefits as treatment and as prevention. However, there is limited information regarding same-day ART initiation in Ethiopia. Hence, this study aimed to assess the magnitude and factors of same-day ART initiation among people living with HIV (PLHIV) on ART at Nekemte specialized hospital, in Western Ethiopia.

Methods

A cross-sectional study was conducted among 483 PLHIV from January 10 to February 15, 2021. Data were collected using an investigator-administered questionnaire. Epi Data 3.1 and STATA 14.0 were used for data entry and analysis, respectively. Variables with P-value <0.25 from bivariable analysis were included in the multivariable analysis. AOR with 95% CI and P-value <0.05 were used to declare statistical significance.

Results

A total of 483 study subjects participated and gave a 100% response rate. Two thirds (65%) of them started ART on the same day with a 95% CI [60.2-68.8]. Urban dwellers (AOR = 3.93 (95% 1.96-7.87)), with no OIs (AOR = 4.02 (95% CI: 1.54-10.47)), not screened for TB (AOR = 6.02 (95% CI: 1.71-21.15)), tested via VCT (AOR = 2.32 (95% CI: 1.37-3.26)), who have not used CPT (AOR = 1.88 (95% CI: 1.10-3.23)), who have not used IPT (AOR = 2.36 (95% CI: 1.0-5.57)), who were tested in 2019/20 (AOR = 2.37 (95% CI: 1.08-5.518)), and with BMI ≥25 kg/m² (AOR = 2.18 (95% CI: 1.05-4.52)) were significantly associated with same-day ART initiation.

Conclusion

Two thirds of study subjects initiated ART on the same day as HIV diagnosis. Voluntary testing and immediate referral to HIV care, advocating test-and-treat, and intensive counseling should be strengthened and reinforced for newly diagnosed HIV-positive people. Given that, high attention should be paid to individuals from urban residence, not screened for TB, who have not used CPT and IPT prophylaxis.

Same-Day Antiretroviral Therapy Initiation as a Predictor of Loss to Follow-up and Viral Suppression Among People With Human Immunodeficiency Virus in Sub-Saharan Africa

BACKGROUND

Treat-All guidelines recommend initiation of antiretroviral therapy (ART) for all people with HIV (PWH) on the day of diagnosis when possible, yet uncertainty exists about the impact of same-day ART initiation on subsequent care engagement. We examined the association of same-day ART initiation with loss to follow-up and viral suppression among patients in 11 sub-Saharan African countries.

METHODS

We included ART-naive adult PWH from sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium who enrolled in care after Treat-All implementation and prior to January 2019. We used multivariable Cox regression to estimate the association between same-day ART initiation and loss to follow-up and Poisson regression to estimate the association between same-day ART initiation and 6-month viral suppression.

RESULTS

Among 29 017 patients from 63 sites, 18 584 (64.0%) initiated ART on the day of enrollment. Same-day ART initiation was less likely among those with advanced HIV disease versus early-stage disease. Loss to follow-up was significantly lower among those initiating ART ≥1 day of enrollment, compared with same-day ART initiators (20.6% vs 27.7%; adjusted hazard ratio: .66; 95% CI .57-.76). No difference in viral suppression was observed by time to ART initiation (adjusted rate ratio: 1.00; 95% CI: .98-1.02).

CONCLUSIONS

Patients initiating ART on the day of enrollment were more frequently lost to follow-up than those initiating later but were equally likely to be virally suppressed. Our findings support recent World Health Organization recommendations for providing tailored counseling and support to patients who accept an offer of same-day ART.

Rapid antiretroviral therapy initiation and its effect on treatment response in MSM in West Africa

OBJECTIVE

To assess the time from HIV diagnosis to ART initiation and the effect of rapid ART initiation (i.e. within 7 days of HIV diagnosis) on attrition and virologic and immunologic responses among MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo.

DESIGN

Prospective cohort study between 2015 and 2019.

METHODS

MSM aged 18 years or older newly diagnosed with HIV infection were eligible to participate. ART was proposed to participants upon HIV diagnosis, irrespective of clinical stage and CD4+ cell count, and was initiated as soon as possible, with no specific time frame. Determinants of rapid ART initiation and its effect on treatment outcomes were assessed using multivariate analyses.

RESULTS

Of 350 MSM, 335 (95.7%) initiated ART after a median time of 5 days. Of the latter, 216 (64.5%) had rapid ART initiation. The 335 participants were followed up for a median time of 24.1 months. One hundred and eleven (33.1%) were not retained in care. Rapid ART initiation was less likely in participants with a CD4+ cell count at least 200 cells/μl [adjusted odds ratio (aOR) 0.37, 95% confidence interval (CI) 0.15-0.88]. It improved viral load suppression (aOR 6.96, 95% CI 1.98-24.46) but had no effect on attrition (aOR 0.87, 95% CI 0.57-1.33) or CD4+ cell count increase (adjusted coefficient 28.23, 95% CI -17.00 to 73.45).

CONCLUSION

These results in MSM in West Africa support the WHO recommendation for rapid ART initiation. Clinics need to develop context-specific strategies for rapid ART initiation and for retaining MSM in HIV care.ClinicalTrials.gov, number NCT02626286.

Retention in care and viral suppression after same-day ART initiation: One-year outcomes of the SLATE I and II individually randomized clinical trials in South Africa

Introduction

Same‐day initiation (SDI) of antiretroviral therapy (ART) for HIV consistently increases ART uptake, but concerns remain about higher attrition from care after initiation. We analysed 12‐month retention in the SLATE SDI trials.

Methods

SLATE I (Simplified Algorithms for Treatment Eligibility I, enrolment 06 March–28 July 2017) and SLATE II (enrolment 14 March–18 September 2018) were individually randomized trials at public outpatient clinics in Johannesburg that enrolled patients not yet on ART and administered the SLATE I or II algorithm. This included a symptom self‐report, medical history, brief physical examination and readiness questionnaire to assess the eligibility for SDI. The studies compared the offer of SDI using the SLATE algorithms to standard of care initiation procedures. ART uptake and early retention were previously reported. Using routine clinic records, we conducted a pooled analysis of retention in care and HIV viral suppression 14 months after study enrolment, a time point equivalent to 12 months potential on ART, with an additional month allowed on either end to initiate ART and to return for the 12‐month visit.

Results and discussion

We enrolled 1193 study participants (standard arms, n = 599, 50%; intervention arms, n = 594, 50%) and analysed by originally assigned groups. By 14 months after enrolment, 50% of intervention arm patients and 46% of standard arm patients remained in care at the initiating site (crude risk difference 4% (95% confidence interval −1%‐10%); crude relative risk 1.10 (0.97–1.23), with similar viral suppression between arms. Observed attrition from care at site by 14 months was high in both study arms, but we found no evidence that the offer of SDI led to greater overall attrition or lower rates of viral suppression 1 year after starting ART and may have generated small improvements. SDI may have shifted some attrition from before to after dispensing of the first dose of medication.

Conclusions

An offer of SDI of ART, following a carefully designed protocol to identify patients who are eligible and ready to start treatment, is not inherently associated with an overall increase in patient attrition from care and leads to similar rates of viral suppression.

How early is too early? Challenges in ART initiation and engaging in HIV care under Treat All in Rwanda-A qualitative study

Introduction

HIV treatment guidelines recommend that all people living with HIV (PLWH) initiate antiretroviral therapy (ART) as soon as possible after diagnosis (Treat All). As Treat All is more widely implemented, an increasing proportion of PLWH are likely to initiate ART when they are asymptomatic, and they may view the relative benefits and risks of ART differently than those initiating at more advanced disease stages. To date, patient perspectives of initiating care under Treat All in sub-Saharan Africa have not been well described.

Methods

From September 2018 to March 2019, we conducted individual, semi-structured, qualitative interviews with 37 patients receiving HIV care in two health centers in Kigali, Rwanda. Data were analyzed using a mixed deductive and inductive thematic analysis approach to describe perceived barriers to, facilitators of and acceptability of initiating and adhering to ART rapidly under Treat All.

Results

Of 37 participants, 27 were women and the median age was 31 years. Participants described feeling traumatized and overwhelmed by their HIV diagnosis, resulting in difficulty accepting their HIV status. Most were prescribed ART soon after diagnosis, yet fear of lifelong medication and severe side effects in the immediate period after initiating ART led to challenges adhering to therapy. Moreover, because many PLWH initiated ART while healthy, taking medications and attending appointments were visible signals of HIV status and highly stigmatizing. Nonetheless, many participants expressed enthusiasm for Treat All as a program that improved health as well as health equity.

Conclusion

For newly-diagnosed PLWH in Rwanda, initiating ART rapidly under Treat All presents logistical and emotional challenges despite the perceived benefits. Our findings suggest that optimizing early engagement in HIV care under Treat All requires early and ongoing intervention to reduce trauma and stigma, and promote both individual and community benefits of ART.
