Initiating Antiretroviral Therapy for HIV at a Patient's First Clinic Visit: The RapIT Randomized Controlled Trial

Impact of rapid-antiretroviral therapy in a cohort of treatment-naïve migrants living with HIV in a high income setting

BACKGROUND

We evaluated the effect of rapid ART (RA) compared to delayed ART (DA) on viral load suppression (viral load <50 cp/mL) and loss to follow-up (LTFU) in a cohort of migrants living with HIV (MLWHs) in Italy.

METHODS

Data were retrospectively gathered from MLWHs who began care at the Infectious and Tropical Diseases Unit of the Careggi University Hospital from January 2014 to December 2022. RA was defined as antiretrovirals prescribed within 7 days of HIV diagnosis. The study ended on April 30, 2023, or upon patient LTFU. Chi-square and non-parametric tests assessed differences in categorical and continuous variables, respectively. Kaplan-Meyer survival analysis was performed to estimate the probability of loss to follow-up. Cox regression analysis was performed to evaluate factors associated with a loss to follow-up.

RESULTS

87 MLWHs were enrolled: 20 (23%) on RA and 67 (77%) on DA. In the RA group there were more PLWH with a previous AIDS event (p < .001) however, there was no significant difference in the LTFU rates between the groups (aHR 0.6, 95%CI 0.1-3.1; p = .560; Logrank = 0.2823). Being an out-of-status MLWH was the only predictor of LTFU. By 6 months, virological suppression was achieved in 61.2% (n = 41) in DA and 70.0% in the RA group (n = 14) (Logrank p = .6747).

CONCLUSIONS

RA did not significantly affect LTFU rates or the achievement of viral load suppression. The study suggests that further research is needed to assess the impact of RA in high income settings.

Evaluation of rapid antiretroviral initiation strategy in a cohort of newly diagnosed people living with HIV in Panama, 2018-2019

Antiretroviral therapy (ART) has been adopted as a form of HIV treatment and prevention. This study assesses rapid ART initiation using clinical outcomes such as viral load (VL) and CD4+ T lymphocytes count. Over the course of one year, the progress of newly diagnosed people living with HIV who started ART early in a hospital in Panama City was followed. The evaluation of early initiation of ART in achieving viral suppression (VL <200 copies/ml) was analyzed using descriptive statistics. Additionally, the cost difference between early (first 7 days) and late initiation of ART was evaluated from the perspective of the service provider. In total, 209 people were followed up during the study; 85% were male, 70% started ART on same day from hospital arrival, 80% had suppressed viral load at 6 months, and the median count of CD4 increased from 285 (IQR: 166-429) to 509 (IQR: 373-696) over 12 months. Starting ART early led to a 42% increase for the provider in terms of staffing costs; however, the clients had the opportunity to decrease absenteeism in daily activities. The results reveal that early initiation of ART generates clinical and economic benefits for the person in treatment.

Real world community-based HIV Rapid Start Antiretroviral with B/F/TAF versus prior models of antiretroviral therapy start - the RoCHaCHa study, a pilot study

BACKGROUND

The rapid start of antiretroviral therapy (RSA) model initiates antiretroviral therapy (ART) as soon as possible after a new or preliminary diagnosis of HIV, in advance of HIV-1 RNA and other baseline laboratory testing. This observational study aims to determine if RSA with a single tablet regimen of bictegravir, emtricitabine, and tenofovir alafenamide (B/F/TAF) is an effective regimen for achieving viral suppression and accepted by patients at the time of diagnosis.

METHODS

Adults newly or preliminarily diagnosed with HIV were enrolled from October 2018 through September 2021. Real world advantage, measured in days between clinical milestones and time to virologic suppression, associated with B/F/TAF RSA was compared to historical controls.

RESULTS

All Study RSA participants (n = 45) accepted treatment at their first visit and 43(95.6%) achieved virologic suppression by week 48. Study RSA participants had a significantly shorter time (median 32 days) from diagnosis to ART initiation and virologic suppression, in comparison to historical controls (median 181 days) (n = 42). Qualitative feedback from study RSA participants showed high acceptance positive response to RSA.

CONCLUSIONS

RSA is feasible and well accepted by patients in a real-world community-based clinic setting. Promoting RSA in community-based clinics is an important tool in ending the HIV epidemic.

Potential Utility of C-reactive Protein for Tuberculosis Risk Stratification Among Patients With Non-Meningitic Symptoms at HIV Diagnosis in Low- and Middle-income Countries

Background

The World Health Organization recommends initiating same-day antiretroviral therapy (ART) while tuberculosis (TB) testing is under way for patients with non-meningitic symptoms at HIV diagnosis, though safety data are limited. C-reactive protein (CRP) testing may improve TB risk stratification in this population.

Methods

In this baseline analysis of 498 adults (>18 years) with TB symptoms at HIV diagnosis who were enrolled in a trial of rapid ART initiation in Haiti, we describe test characteristics of varying CRP thresholds in the diagnosis of TB. We also assessed predictors of high CRP as a continuous variable using generalized linear models.

Results

Eighty-seven (17.5%) participants were diagnosed with baseline TB. The median CRP was 33.0 mg/L (interquartile range: 5.1, 85.5) in those with TB, and 2.6 mg/L (interquartile range: 0.8, 11.7) in those without TB. As the CRP threshold increased from ≥1 mg/L to ≥10 mg/L, the positive predictive value for TB increased from 22.4% to 35.4% and negative predictive value decreased from 96.9% to 92.3%. With CRP thresholds varying from <1 to <10 mg/L, a range from 25.5% to 64.9% of the cohort would have been eligible for same-day ART and 0.8% to 5.0% would have untreated TB at ART initiation.

Conclusions

CRP concentrations can be used to improve TB risk stratification, facilitating same-day decisions about ART initiation. Depending on the CRP threshold, one-quarter to two-thirds of patients could be eligible for same-day ART, with a reduction of 3- to 20-fold in the proportion with untreated TB, compared with a strategy of same-day ART while awaiting TB test results.

Impact of antiretroviral therapy during acute or early HIV infection on virologic and immunologic outcomes: results from a multinational clinical trial

OBJECTIVE

To assess how antiretroviral therapy (ART) initiation during acute or early HIV infection (AEHI) affects the viral reservoir and host immune responses.

DESIGN

Single-arm trial of ART initiation during AEHI at 30 sites in the Americas, Africa, and Asia.

METHODS

HIV DNA was measured at week 48 of ART in 5 million CD4 + T cells by sensitive qPCR assays targeting HIV gag and pol . Peripheral blood mononuclear cells were stimulated with potential HIV T cell epitope peptide pools consisting of env , gag , nef, and pol peptides and stained for expression of CD3, CD4, CD8, and intracellular cytokines/chemokines.

RESULTS

From 2017 to 2019, 188 participants initiated ART during Fiebig stages I ( n  = 6), II ( n  = 43), III ( n  = 56), IV ( n  = 23), and V ( n  = 60). Median age was 27 years (interquartile range 23-38), 27 (14%) participants were female, and 180 (97%) cisgender. Among 154 virally suppressed participants at week 48, 100% had detectable HIV gag or pol DNA. Participants treated during Fiebig I had the lowest HIV DNA levels ( P  < 0.001). Week 48 HIV DNA mostly did not correlate with concurrent CD4 + or CD8 + T cell HIV-specific immune responses (rho range -0.11 to +0.19, all P  > 0.025). At week 48, the magnitude, but not polyfunctionality, of HIV-specific T cell responses was moderately reduced among participants who initiated ART earliest.

CONCLUSION

Earlier ART initiation during AEHI reduced but did not eliminate the persistence of HIV-infected cells in blood. These findings explain the rapid viral rebound observed after ART cessation in early-treated individuals with undetectable HIV DNA by less sensitive methods.

Predictors of Clinical Outcomes among People with HIV and Tuberculosis Symptoms after Rapid Treatment Initiation in Haiti

Introduction

Few studies have evaluated baseline predictors of clinical outcomes among people with HIV starting antiretroviral therapy (ART) in the modern era of rapid ART initiation.

Methods

We conducted a secondary analysis of a randomized controlled trial of two rapid treatment initiation strategies for people with treatment-naïve HIV and tuberculosis symptoms at an urban clinic in Haiti. We used logistic regression models to assess associations between baseline characteristics and (1) retention in care at 48 weeks, (2) HIV viral load suppression at 48 weeks (among participants who underwent viral load testing), and (3) all-cause mortality.

Results

500 participants were enrolled in the study 11/2017-1/2020. Eighty-eight (18%) participants were diagnosed with tuberculosis, and ART was started in 494 (99%). After adjustment, less than secondary education (adjusted odds ratio [AOR] 0.21, 95% CI 0.10-0.46), dolutegravir initiation (AOR 2.57, 95% CI 1.22-5.43), age (AOR 1.42 per 10-year increase, 95% CI 1.01-1.99), and tuberculosis diagnosis (AOR 3.92, 95% CI 1.36-11.28) were significantly associated with retention. Age (AOR 1.36, 95% CI 1.05-1.75), dolutegravir initiation (AOR 1.75, 95% CI 1.07-2.85), and tuberculosis diagnosis (AOR 0.50, 95% CI 0.28-0.89) were associated with viral suppression. Higher CD4 cell count at enrollment (unadjusted odds ratio [OR] 0.69, 95% CI 0.55-0.87) and anemia (OR 4.86, 95% CI 1.71-13.81) were associated with mortality.

Conclusions

We identified sociodemographic, treatment-related, clinical, and laboratory-based predictors of clinical outcomes. These characteristics may serve as markers of sub-populations that could benefit from additional interventions to support treatment success after rapid treatment initiation.

Pharmacist-Driven Rapid Initiation of Antiretroviral Therapy Decreases Time to Viral Suppression in People With HIV

Background

Rapid initiation of antiretroviral therapy (rapid ART) improves clinical outcomes in people with HIV and is endorsed by clinical guidelines. However, logistical challenges limit widespread implementation. We describe an innovative rapid ART model led by pharmacists and its impact on clinical outcomes, including time to viral suppression (TVS).

Methods

On 1 January 2019, we implemented Pharmacist-Driven Rapid ART (PHARM-D RAPID ART), including rapid ART initiation by pharmacists. Our retrospective cohort study compared TVS, using a Cox proportional hazards model, and clinical outcomes among individuals with a new HIV diagnosis before (1 January 2017 to 31 December 2017) and after (1 January 2019 to 31 December 2019) implementation.

Results

A total of 108 individuals were included. TVS was significantly shorter (P < .001) for the PHARM-D RAPID ART group (n = 51) compared with the preimplementation group (n = 57) (median: 30 days and 66 days, respectively). Those in the PHARM-D RAPID ART group were significantly more likely to achieve VS at any given time during the study period (adjusted hazard ratio: 3.47 [95% confidence interval, 2.25-5.33]). A total of 94.1% (48/51) of patients in the PHARM-D RAPID ART group were retained in care at 1 year. With a median follow-up of 2.4 years in the PHARM-D RAPID ART group, 98% remained suppressed at last recorded viral load.

Conclusions

A pharmacist-driven model for rapid ART delivery decreases TVS with high rates of retention in care and durable VS. This model could improve clinical outcomes and increase program feasibility and sustainability.

Perceptions of Rapid Antiretroviral Therapy Initiation Among Participants of The Netherlands Cohort Study on Acute HIV Infection

Starting antiretroviral therapy (ART) same-day, or as soon as possible after HIV diagnosis is advised in guidelines worldwide. Especially during acute HIV infection (AHI), rapid ART start may be more urgent because of a higher risk of transmission or symptoms of acute retroviral syndrome. During this phase, rapid ART start may have additional benefits for viral reservoir size and host immunity. We explored perceptions of rapid ART start among participants of The Netherlands Cohort Study on Acute HIV infection (NOVA study), who started ART rapidly after diagnosis of AHI. We conducted 20 in-depth qualitative interviews with NOVA study participants between October and December 2018. Data were analyzed thematically, using inductive and iterative coding techniques. Roughly half of the participants stated they felt well-informed about the importance of (rapid) ART. Starting ART rapidly was perceived positively by almost all participants, mostly because of the expected benefits on their health, and to prevent HIV transmission. Rapid ART start was seen as a way to cope with the diagnosis. However, a more negative perception was that rapid ART start confronted participants with their diagnosis, when they were still adjusting to a new situation. Our results show that among people diagnosed during AHI, rapid ART is well-accepted. These results should be encouraging to HIV care providers who encounter people with AHI in their clinical practice and to researchers who carry out cure-related studies, in which early ART is often included. The Clinical Trial Registration number is NCT05728996.

Improving patient-centred counselling skills among lay healthcare workers in South Africa using the Thusa-Thuso motivational interviewing training and support program

We developed a motivational interviewing (MI) counselling training and support program for lay counsellors in South Africa-branded "Thusa-Thuso-helping you help", commonly referred to as Thusa-Thuso. We present the results of a pilot study to determine the program's impact on MI technical skills and qualitatively assess the feasibility of a training-of-trainers (TOT) scale-up strategy among counselling staff of non-governmental (NGO) support partners of the human immunodeficiency virus (HIV) treatment program in South Africa. We enrolled adult (≥ 18 years) lay counsellors from ten primary healthcare clinics in Johannesburg (South Africa) selected to participate in the Thusa-Thuso training and support program. Counsellors attended the ten-day baseline and quarterly refresher training over 12 months (October 2018-October 2019). Each counsellor submitted two audio recordings of mock counselling sessions held during the ten-day baseline training and two additional recordings of sessions with consenting patients after each quarterly contact session. We reviewed the recordings using the MI treatment integrity (MITI) coding system to determine MI technical (cultivating change talk and softening sustain talk) and relational (empathy and partnership) competency scores before and after training. After 12 months of support with pilot site counsellors, we were asked to scale up the training to NGO partner team trainers in a once-off five-day Training of trainers (TOT) format (n = 127 trainees from November 2020 to January 2021). We report TOT training experiences from focus group discussions (n = 42) conducted six months after the TOT sessions. Of the 25 enrolled lay counsellors from participating facilities, 10 completed the 12-month Thusa-Thuso program. Attrition over the 12 months was caused by death (n = 3), site exclusion/resignations (n = 10), and absence (n = 2). MI competencies improved as follows: the technical skills score increased from a mean of 2.5 (standard deviation (SD): 0.8) to 3.1 (SD: 0.5), with a mean difference of 0.6 (95% confidence interval (CI): 0.04, 0.9). The MI relational skills score improved from a mean of 3.20 (SD: 0.7) to 3.5 (SD: 0.6), with a mean difference of 0.3 (95% CI: -0.3, 8.5). End-point qualitative data from the counsellors highlighted the value of identifying and addressing specific skill deficiencies and the importance of counsellors being able to self-monitor skill development using the MITI review process. Participants appreciated the ongoing support to clarify practical MI applications. The TOT program tools were valuable for ongoing on-the-job development and monitoring of quality counselling skills. However, the MITI review process was perceived to be too involved for large-scale application and was adapted into a scoring form to document sit-in mentoring sessions. The Thusa-Thuso MI intervention can improve counsellor motivation and skills over time. In addition, the program can be scaled up using an adapted TOT process supplemented with fidelity assessment tools, which are valuable for skills development and ongoing maintenance. However, further studies are needed to determine the effect of the Thusa-Thuso program on patient ART adherence and retention in care.

Rapid Initiation of Antiretroviral Therapy Under the Treat-All Policy Reduces Loss to Follow-Up and Virological Failure in Routine Human Immunodeficiency Virus Care Settings in China: A Retrospective Cohort Study (2016-2022)

Following the World Health Organization's guidelines for rapid antiretroviral therapy (ART) initiation [≤7 days after human immunodeficiency virus (HIV) diagnosis], China implemented Treat-All in 2016 and has made significant efforts to provide timely ART since 2017. This study included newly diagnosed HIV adults from Tianjin, China, between 2016 and 2022. Our primary outcome was loss to follow-up (LTFU) at 12 months after enrollment. The secondary outcome was 12-month virological failure. The association between rapid ART and LTFU, as well as virological failure, was assessed via Cox regression and logistic regression. A total of 896 (19.1%) of 4688 participants received ART ≤7 days postdiagnosis. The rate of rapid ART has increased from 7.5% in 2016 to 33.3% by 2022. The rapid ART group had an LTFU rate of 3.3%, as opposed to 5.0% in the delayed group. The rapid ART group had a much reduced virological failure rate (0.6% vs. 1.8%). Rapid ART individuals had a reduced likelihood of LTFU [adjusted hazard ratio: 0.65, 95% confidence intervals (CI): 0.44-0.96] and virological failure (adjusted odds ratio: 0.35, 95% CI: 0.12-0.80). The real-world data indicated that rapid ART is practicable and beneficial for Chinese people with HIV, providing evidence for its widespread implementation and scaling up.

Rapid antiretroviral therapy in primary HIV-1 infection enhances immune recovery

OBJECTIVE

We present findings from a large cohort of individuals treated during primary HIV infection (PHI) and examine the impact of time from HIV-1 acquisition to antiretroviral therapy (ART) initiation on clinical outcomes. We also examine the temporal changes in the demographics of individuals presenting with PHI to inform HIV-1 prevention strategies.

METHODS

Individuals who fulfilled the criteria of PHI and started ART within 3 months of confirmed HIV-1 diagnosis were enrolled between 2009 and 2020. Baseline demographics of those diagnosed between 2009 and 2015 (before preexposure prophylaxis (PrEP) and universal ART availability) and 2015-2020 (post-PrEP and universal ART availability) were compared. We examined the factors associated with immune recovery and time to viral suppression.

RESULTS

Two hundred four individuals enrolled, 144 from 2009 to 2015 and 90 from 2015 to 2020; median follow-up was 33 months. At PHI, the median age was 33 years; 4% were women, 39% were UK-born, and 84% were MSM. The proportion of UK-born individuals was 47% in 2009-2015, compared with 29% in 2015-2020. There was an association between earlier ART initiation after PHI diagnosis and increased immune recovery; each day that ART was delayed was associated with a lower likelihood of achieving a CD4 + cell count more than 900 cells/μl [hazard ratio 0.99 (95% confidence interval, 95% CI 0.98-0.99), P  = 0.02) and CD4/CD8 more than 1.0 (hazard ratio 0.98 (95% CI 0.97-0.99).

CONCLUSION

Early initiation of ART at PHI diagnosis is associated with enhanced immune recovery, providing further evidence to support immediate ART in the context of PHI. Non-UK-born MSM accounts for an increasing proportion of those with primary infection; UK HIV-1 prevention strategies should better target this group.

Physiologically-based pharmacokinetic modelling of long-acting injectable cabotegravir and rilpivirine in pregnancy

AIMS

Long-acting cabotegravir and rilpivirine have been approved to manage HIV in adults, but data regarding safe use in pregnancy are limited. Physiologically-based pharmacokinetic (PBPK) modelling was used to simulate the approved dosing regimens in pregnancy and explore if Ctrough was maintained above cabotegravir and rilpivirine target concentrations (664 and 50 ng/mL, respectively).

METHODS

An adult PBPK model was validated using clinical data of cabotegravir and rilpivirine in nonpregnant adults. This was modified by incorporating pregnancy-induced metabolic and physiological changes. The pregnancy PBPK model was validated with data on oral rilpivirine and raltegravir (UGT1A1 probe substrate) in pregnancy. Twelve weeks' disposition of monthly and bimonthly dosing of long-acting cabotegravir and rilpivirine was simulated at different trimesters and foetal exposure was also estimated.

RESULTS

Predicted Ctrough at week 12 for monthly long-acting cabotegravir was above 664 ng/mL throughout pregnancy, but below the target in 0.5% of the pregnant population in the third trimester with bimonthly long-acting cabotegravir. Predicted Ctrough at week 12 for monthly and bimonthly long-acting rilpivirine was below 50 ng/mL in at least 40% and over 90% of the pregnant population, respectively, throughout pregnancy. Predicted medians (range) of cord-to-maternal blood ratios were 1.71 (range, 1.55-1.79) for cabotegravir and 0.88 (0.78-0.93) for rilpivirine between weeks 38 and 40.

CONCLUSIONS

Model predictions suggest that monthly long-acting cabotegravir could maintain antiviral efficacy throughout pregnancy, but that bimonthly administration may require careful clinical evaluation. Both monthly and bimonthly long-acting rilpivirine may not adequately maintain antiviral efficacy in pregnancy.

Same-day versus rapid ART initiation in HIV-positive individuals presenting with symptoms of tuberculosis: Protocol for an open-label randomized non-inferiority trial in Lesotho and Malawi

BACKGROUND

In absence of contraindications, same-day initiation (SDI) of antiretroviral therapy (ART) is recommended for people testing HIV-positive who are ready to start treatment. Until 2021, World Health Organization (WHO) guidelines considered the presence of TB symptoms (presumptive TB) a contraindication to SDI due to the risk of TB-immune reconstitution inflammatory syndrome (TB-IRIS). To reduce TB-IRIS risk, ART initiation was recommended to be postponed until results of TB investigations were available, and TB treatment initiated if active TB was confirmed. In 2021, the WHO guidelines changed to recommending SDI even in the presence of TB symptoms without awaiting results of TB investigations based on the assumption that TB investigations often unnecessarily delay ART initiation, increasing the risk for pre-ART attrition from care, and noting that the clinical relevance of TB-IRIS outside the central nervous system remains unclear. However, this guideline change was not based on conclusive evidence, and it remains unclear whether SDI of ART or TB test results should be prioritized in people with HIV (PWH) and presumptive TB.

DESIGN AND METHODS

SaDAPT is an open-label, pragmatic, parallel, 1:1 individually randomized, non-inferiority trial comparing two strategies for the timing of ART initiation in PWH with presumptive TB ("ART first" versus "TB results first"). PWH in Lesotho and Malawi, aged 12 years and older (re)initiating ART who have at least one TB symptom (cough, fever, night sweats or weight loss) and no signs of intracranial infection are eligible. After a baseline assessment, participants in the "ART first" arm will be offered SDI of ART, while those in the "TB results first" arm will be offered ART only after active TB has been confirmed or refuted. We hypothesize that the "ART first" approach is safe and non-inferior to the "TB results first" approach with regard to HIV viral suppression (<400 copies/ml) six months after enrolment. Secondary outcomes include retention in care and adverse events consistent with TB-IRIS.

EXPECTED OUTCOMES

SaDAPT will provide evidence on the safety and effects of SDI of ART in PWH with presumptive TB in a pragmatic clinical trial setting.

TRIAL REGISTRATION

The trial has been registered on clinicaltrials.gov (NCT05452616; July 11 2022).

Rapid initiation of antiretroviral therapy in Turkey: a modeling study

Background

To effectively control the HIV epidemic and meet global targets, policymakers recommend the rapid initiation of antiretroviral therapy (ART). Our study aims to investigate the effect of rapid ART programs on individuals diagnosed with HIV, considering varying coverage and initiation days after diagnosis, and compare it to standard-of-care ART treatment in Turkey.

Methods

We used a dynamic compartmental model to simulate the dynamics of HIV infection in Turkey. Rapid treatment, defined as initiation of ART within 7 days of diagnosis, was contrasted with standard-of-care treatment, which starts within 30 days of diagnosis. This study considered three coverage levels (10%, 50%, and 90%) and two rapid periods (7 and 14 days after diagnosis), comparing them to standard-of-care treatment in evaluating the number of HIV infections between 2020 and 2030.

Results

Annual HIV incidence and prevalence for a 10-year period were obtained from model projections. In the absence of a rapid ART program, the model projected approximately 444,000 new HIV cases while the number of cases were reduced to 345,000 (22% reduction) with 90% of diagnosed cases included in the rapid ART program. Similarly, 10% and 50% rapid ART coverage has resulted in 3% and 13% reduction in HIV prevalence over a 10-year period.

Conclusion

Rapid ART demonstrates the potential to mitigate the increasing HIV incidence in Turkey by reducing the number of infections. The benefit of the rapid ART program could be substantial when the coverage of the program reaches above a certain percentage of diagnosed population.

Rapid ART initiation with bictegravir/emtricitabine/tenofovir alafenamide in individuals presenting with advanced HIV disease (Rainbow study)

BACKGROUND

A rapid ART initiation approach can be beneficial in people with advanced HIV disease, in consideration of their high morbidity and mortality. The aim of our study was to evaluate the feasibility, efficacy and safety of rapid ART start with BIC/FTC/TAF in this setting.

METHODS

Pilot, single-centre, single-arm, prospective, phase IV clinical trial conducted in a tertiary Italian hospital. Thirty ART-naïve people presenting with advanced HIV-1 diagnosis (defined as the presence of an AIDS-defining event and/or CD4 cell count <200 µL), were enrolled. Main exclusion criteria were active tuberculosis, cryptococcosis and pregnant/breastfeeding women. BIC/FTC/TAF was started within 7 days from HIV diagnosis. The primary endpoint was clinical or virologic failure (VF). Immunological parameters, safety, feasibility, neurocognitive performances and patient-reported outcomes were assessed as well.

RESULTS

Over the study period, 40 (34%) of 116 patients diagnosed with HIV infection at INMI Spallanzani had advanced disease, of whom 30 (26%) were enrolled. The proportion of participants with HIV-RNA <50 cp/mL was 9/30 (30%) at week (w) 4, 19/30 (63%) at w12, 24/30 (80%) at w24, 23/30 (77%) at w36 and 27/30 (90%) at w48. Two unconfirmed VF occurred. No ART discontinuation due to toxicity or VF was observed. No ART modification was performed based on the review of genotype and no mutations for the study drugs were detected. Mean CD4 cells count changed by 133 cells/μL at BL to 309 cells/μL at w 48 and 83% of participants had a CD4 > 200 cells/µL at w 48. Two participants developed IRIS and one was diagnosed with disseminated TB and needed an ART switch.

INTERPRETATIONS

Our results support the feasibility, efficacy and safety of BIC/FTC/TAF as a rapid ART strategy in patients with advanced HIV disease.

Rapid Start of Antiretroviral Therapy in a Large Urban Clinic in the US South: Impact on HIV Care Continuum Outcomes and Medication Adherence

Rapid start of antiretroviral therapy (ART) has been associated with improvement in several HIV-related outcomes in clinical trials as well as demonstration projects, but how regional and contextual differences may affect the effectiveness of this intervention necessitates further study. In this study of a large, urban, Southern US clinic-based retrospective cohort, we identified 544 patients with a new diagnosis of HIV during 2016 to 2019 and compared HIV care continuum outcomes for the first 12 months of care before and after rapid start implementation. Kaplan-Meier time-to-event curves were used to summarize time to virologic suppression, and stepwise Cox, linear, and logistic regression models were used to create multivariate models to evaluate the association between rapid start and time to virologic suppression, medication adherence, and retention in care and sustained virologic suppression, respectively. We found that rapid start was significantly associated with improved medication adherence scores (+15.37 points, 95% confidence interval [CI] 9.36-21.39, P < .01) and retention in care (adjusted odds ratio = 1.51, 95% CI 1.05-2.19, P = .03). Time to virologic suppression (median 2.46 months before, 2.56 months after rapid start) and sustained virologic suppression were not associated with rapid start in our setting. Though rapid start was associated with improved medication adherence and retention in care, more support may be needed to achieve the same outcomes seen in other studies and sustained over the entire HIV care continuum, especially in settings with significant patient and systemic barriers to care such as unstable housing, lack of Medicaid expansion, and frequent coverage interruptions.

Potential Utility of C-reactive Protein for Tuberculosis Risk Stratification among Patients with Non-Meningitic Symptoms at HIV Diagnosis in Low- and Middle-Income Countries

Article Summary

We assessed the association between C-reactive protein (CRP) and Mycobacterium tuberculosis (TB) diagnosis in symptomatic patients at HIV diagnosis. We found that CRP concentrations can improve tuberculosis risk stratification, facilitating decision making about whether (specific) tuberculosis testing is indicated before antiretroviral therapy initiation.

Background

The World Health Organization recommends initiating same-day ART while tuberculosis testing is underway for patients with non-meningitic symptoms at HIV diagnosis, though safety data are limited. C-reactive protein (CRP) testing may improve tuberculosis risk stratification in this population.

Methods

In this baseline analysis of 498 adults (>18 years) with tuberculosis symptoms at HIV diagnosis who were enrolled in a trial of rapid ART initiation in Haiti, we describe test characteristics of varying CRP thresholds in the diagnosis of TB. We also assessed predictors of high CRP (≥3 mg/dL) using generalized linear models.

Results

Eighty-seven (17.5%) patients were diagnosed with baseline TB. The median CRP was 33.0 mg/L (IQR: 5.1, 85.5) in those with TB, and 2.6 mg/L (IQR: 0.8, 11.7) in those without TB. As the CRP threshold increased from ≥1 mg/L to ≥10 mg/L, the positive predictive value for TB increased from 22.4% to 35.4%, and negative predictive value decreased from 96.9% to 92.3%. With CRP thresholds varying from <1 to <10 mg/L, a range from 25.5% to 64.9% of the cohort would have been eligible for same-day ART, and 0.8% to 5.0% would have untreated TB at ART initiation.

Conclusions

CRP concentrations can be used to improve TB risk stratification, facilitating same-day decisions about ART initiation. Depending on the CRP threshold, one-quarter to two-thirds of patients could be eligible for same-day ART, with a reduction of 3-fold to 20-fold in the proportion with untreated TB, compared with a strategy of same-day ART while awaiting TB test results.

Does the rapid initiation of antiretroviral therapy at HIV diagnosis impact virological response in a real-life setting? A single-centre experience in Northern Italy

Rapid initiation of antiretroviral therapy (ART) has been proven efficacious and safe, but more investigations are needed to define feasibility of rapid ART approach in real-life settings.We conducted a retrospective, observational study on newly HIVdiagnosed patients referred to our Infectious Diseases Department from September 1st, 2015, to July 31st, 2019. According to the timing of ART initiation, we distinguished 3 groups of patients (rapid, intermediate and late group) and represented the trend of virological response during a 400-days-period. The hazard ratios of each predictor on viral suppression were estimated through the Cox proportional hazard model.The median time from HIV diagnosis to the first medical referral was 15 days and the median time from the first care access to therapy start was 24 days. Among patients, 37.6% started ART within 7 days, 20.6% between 8 and 30 days, and 41.8% after 30 days. Longer time to ART start and higher baseline viral load were associated with a lower probability of viral suppression. After one year, all groups showed a high viral suppression rate (99%). In a high-income setting the rapid ART approach seems useful to accelerate viral suppression which is great over time regardless of ART initiation timing.

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.

Impact of the COVID-19 pandemic on routine HIV care and antiretroviral treatment outcomes in Kenya: A nationally representative analysis

BACKGROUND

The COVID-19 pandemic adversely disrupted global health service delivery. We aimed to assess impact of the pandemic on same-day HIV diagnosis/ART initiation, six-months non-retention and initial virologic non-suppression (VnS) among individuals starting antiretroviral therapy (ART) in Kenya.

METHODS

Individual-level longitudinal service delivery data were analysed. Random sampling of individuals aged >15 years starting ART between April 2018 -March 2021 was done. Date of ART initiation was stratified into pre-COVID-19 (April 2018 -March 2019 and April 2019 -March 2020) and COVID-19 (April 2020 -March 2021) periods. Mixed effects generalised linear, survival and logistic regression models were used to determine the effect of COVID-19 pandemic on same-day HIV diagnosis/ART initiation, six-months non-retention and VnS, respectively.

RESULTS

Of 7,046 individuals sampled, 35.5%, 36.0% and 28.4% started ART during April 2018 -March 2019, April 2019 -March 2020 and April 2020 -March 2021, respectively. Compared to the pre-COVID-19 period, the COVID-19 period had higher same-day HIV diagnosis/ART initiation (adjusted risk ratio [95% CI]: 1.09 [1.04-1.13], p<0.001) and lower six-months non-retention (adjusted hazard ratio [95% CI]: 0.66 [0.58-0.74], p<0.001). Of those sampled, 3,296 (46.8%) had a viral load test done at a median 6.2 (IQR, 5.3-7.3) months after ART initiation. Compared to the pre-COVID-19 period, there was no significant difference in VnS during the COVID-19 period (adjusted odds ratio [95% CI]: 0.79 [95%% CI: 0.52-1.20], p = 0.264).

CONCLUSIONS

In the short term, the COVID-19 pandemic did not have an adverse impact on HIV care and treatment outcomes in Kenya. Timely, strategic and sustained COVID-19 response may have played a critical role in mitigating adverse effects of the pandemic and point towards maturity, versatility and resilience of the HIV program in Kenya. Continued monitoring to assess long-term impact of the COVID-19 pandemic on HIV care and treatment program in Kenya is warranted.

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.

The impact of community-based integrated HIV and sexual and reproductive health services for youth on population-level HIV viral load and sexually transmitted infections in Zimbabwe: protocol for the CHIEDZA cluster-randomised trial

BACKGROUND

Youth have poorer HIV-related outcomes when compared to other age-groups. We describe the protocol for a cluster randomised trial (CRT) to evaluate the effectiveness of community-based, integrated HIV and sexual and reproductive health services for youth on HIV outcomes.

PROTOCOL

The CHIEDZA trial is being conducted in three provinces in Zimbabwe, each with eight geographically demarcated areas (clusters) (total 24 clusters) randomised 1:1 to standard of care (existing health services) or to the intervention. The intervention comprises community-based delivery of HIV services including testing, antiretroviral therapy, treatment monitoring and adherence support as well as family planning, syndromic management of sexually transmitted infections (STIs), menstrual health management, condoms and HIV prevention and general health counselling. Youth aged 16-24 years living within intervention clusters are eligible to access CHIEDZA services. A CRT of STI screening (chlamydia, gonorrhoea and trichomoniasis) is nested in two provinces (16 of 24 clusters). The intervention is delivered over a 30-month period by a multidisciplinary team trained and configured to provide high-quality, youth friendly services.Outcomes will be ascertained through a population-based survey of 18-24-year-olds. The primary outcome is HIV viral load <1000 copies/ml in those living with HIV and proportion who test positive for STIs (for the nested trial). A detailed process and cost evaluation of the trial will be conducted.

ETHICS AND DISSEMINATION

The trial protocol was approved by the Medical Research Council of Zimbabwe, the Biomedical Research and Training Institute Institutional Review Board and the London School of Hygiene & Tropical Medicine Research Ethics Committee. Results will be submitted to open-access peer-reviewed journals, presented at academic meetings and shared with participating communities and with national and international policy-making bodies.

Lessons learned from U.S. rapid antiretroviral therapy initiation programs

BACKGROUND

Rapid antiretroviral therapy initiation (R-ART) for treatment of HIV has been recommended since 2017, however it has not been adopted widely across the US.

PURPOSE

The study purpose was to understand facilitators and barriers to R-ART implementation in the U.S.

RESEARCH DESIGN

This was a qualitative design involving semi-structured interviews.

STUDY SAMPLE

The study sample was comprised of the medical leadership of nine US HIV clinics that were early implementers of R-ART.

DATA COLLECTION AND ANALYSIS

In-depth, semi-structured interviews were performed. The Consolidated Framework for Implementation Research (CFIR) was used to guide thematic analysis.

RESULTS

We identified three main content areas: strong scientific rationale for R-ART, buy-in from multiple key stakeholders, and the condensed timeline of R-ART. The CFIR construct of Evidence Strength and Quality was cited as an important factor in R-ART implementation. Buy-in from key stakeholders and immediate access to medications ensured the success of R-ART implementation. Patient acceptance of the condensed timeline for ART initiation was facilitated when presented in a patient-centered manner, including empathetic communication and addressing other patient needs concurrently. The condensed timeline of R-ART presented logistical challenges and opportunities for the development of intense patient-provider relationships.

CONCLUSIONS

Results from the analysis showed that R-ART implementation should address the following: 1) logistical planning to implement HIV treatment with a condensed timeline 2) patients' mixed reactions to a new HIV diagnosis and 3) the high cost of HIV medications.

Experiences of initiating rapid antiretroviral therapy among people newly diagnosed with HIV in East London: a qualitative study

OBJECTIVES

We aimed to explore the experiences of people who initiated rapid antiretroviral therapy (ART) within 7 days of HIV diagnosis, as part of routine care in London.

METHODS

Using purposive sampling, 18 in-depth, semistructured interviews were conducted between December 2020 and September 2021 with people who started rapid ART at Barts Health NHS Trust. Participants aged 22-69 years included 15 cisgender men and three cisgender women. Five identified as heterosexual and 13 as gay and bisexual and other men who have sex with men. Ethnic identities: six White Non-UK, five White UK, three Black Caribbean, two South Asian and two East Asian. Interviews explored feelings about the new HIV diagnosis, attitudes to rapid ART including barriers to and facilitators of starting. Thematic analysis of transcribed interviews was undertaken.

RESULTS

Four themes were identified: (1) being offered rapid ART is acceptable; (2) it is a way of taking control of their health; (3) the need for information and support and (4) an individualised approach to care. Reasons for starting included getting well, staying well and reducing the likelihood of passing on HIV. Facilitators included being given comprehensive information about treatment and managing potential side-effects and a supportive clinical team. Support specified included a non-judgemental attitude, approachability, reassurance, encouragement and information about peer support. Most participants expressed they could not understand why people would not begin treatment, but suggested needing more time to decide and denial of diagnosis as possible barriers.

CONCLUSIONS

To our knowledge, this is the first qualitative study exploring the experiences of people initiating rapid ART in the UK. It was deemed acceptable to an ethnically diverse, predominantly male sample of people newly diagnosed with HIV. Future research should include strategies to recruit a more gender diverse sample and those who declined or stopped rapid ART.

Outcomes and Predictors of Rapid Antiretroviral Therapy Initiation for People With Newly Diagnosed HIV in an Integrated Health Care System

Background

Rapid antiretroviral therapy (ART) is the recommended treatment strategy for patients newly diagnosed with HIV, but the literature supporting this strategy has focused on short-term outcomes. We examined both long-term outcomes and predictors of rapid ART among patients newly diagnosed with HIV within an integrated health care system in Northern California.

Methods

This observational cohort study included adults newly diagnosed with HIV between January 2015 and December 2020 at Kaiser Permanente Northern California. Rapid ART was defined as ART initiation within 7 days of HIV diagnosis. We collected demographic and clinical data to determine short-term and long-term outcomes, including viral suppression, care retention, medication adherence, and cumulative viral burden. Logistic regression models were used to identify predictors of rapid ART initiation.

Results

We enrolled 1409 adults; 34.1% initiated rapid ART. The rapid ART group achieved viral suppression faster (48 vs 77 days; P < .001) and experienced lower cumulative viral burden (log10 viremia copy-years, 3.63 vs 3.82; P < .01) but had slightly reduced medication adherence (74.8% vs 75.2%; P < .01). There was no improvement in long-term viral suppression and care retention in the rapid group during follow-up. Patients were more likely to initiate rapid ART after 2017 and were less likely if they required an interpreter.

Conclusions

Patients who received rapid ART had an improved cumulative HIV burden but no long-term improvement in care retention and viral suppression. Our findings suggest that rapid ART should be offered but additional interventions may be needed for patients newly diagnosed with HIV.

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.

HIV test-and-treat policy improves clinical outcomes in Zambian adults from Southern Province: a multicenter retrospective cohort study

Background

Globally, most countries have implemented a test-and-treat policy to reduce morbidity and mortality associated with HIV infection. However, the impact of this strategy has not been critically appraised in many settings, including Zambia. We evaluated the retention and clinical outcomes of adults enrolled in antiretroviral therapy (ART) and assessed the impact of the test-and-treat policy.

Methods

We conducted a retrospective cohort study among 6,640 individuals who initiated ART between January 1, 2014 and July 31, 2016 [before test-and-treat cohort (BTT), n = 2,991] and between August 1, 2016 and October 1, 2020 [after test-and-treat cohort (ATT), n = 3,649] in 12 districts of the Southern province. To assess factors associated with retention, we used logistic regression (xtlogit model).

Results

The median age [interquartile range (IQR)] was 34.8 years (28.0, 42.1), and 60.2% (n = 3,995) were women. The overall retention was 83.4% [95% confidence interval (CI) 82.6, 84.4], and it was significantly higher among the ATT cohort, 90.6 vs. 74.8%, p < 0.001. The reasons for attrition were higher in the BTT compared to the ATT cohorts: stopped treatment (0.3 vs. 0.1%), transferred out (9.3 vs. 3.2%), lost to follow-up (13.5 vs. 5.9%), and death (1.4 vs. 0.2%). Retention in care was significantly associated with the ATT cohort, increasing age and baseline body mass index (BMI), rural residence, and WHO stage 2, while non-retention was associated with never being married, divorced, and being in WHO stage 3.

Conclusion

The retention rate and attrition factors improved in the ATT compared to the BTT cohorts. Drivers of retention were test-and-treat policy, older age, high BMI, rural residence, marital status, and WHO stage 1. Therefore, there is need for interventions targeting young people, urban residents, non-married people, and those in the symptomatic WHO stages and with low BMI. Our findings highlight improved ART retention after the implementation of the test-and-treat policy.

Immediate initiation of antiretroviral treatment: knowledge, attitudes, and practices among clinic staff in New York City

BACKGROUND

Immediate initiation of antiretroviral treatment (iART) is a proven intervention that significantly decreases time to viral suppression and increases patient retention. iART involves starting medication as early as possible, often after a reactive rapid HIV test or re-engagement in care, although it does not have a universal definition. We aimed to understand iART from an implementation science perspective in a wide range of New York City (NYC) clinics providing HIV primary care, including staff knowledge, attitudes, and practices, as well as clinic barriers and facilitators to iART.

METHODS

We used a mixed-methods, convergent study design, with a quantitative survey and in-depth interview (IDI), to understand individual-level knowledge, attitudes, and practices, as well as clinic-level barriers and facilitators to iART. We recruited at least one medical and non-medical staff member from a diverse purposive sample of 30 NYC clinics. In quantitative analyses, we used separate binomial logistic regression models to estimate odds ratios (OR) and 95% confidence intervals (95% CI). In qualitative analyses, we used codebooks created by thematic analyses structured using a Framework Model to develop descriptive analytic memos.

RESULTS

Recruited staff completed 46 surveys and 17 IDIs. We found high levels of awareness of the viral suppression and retention in care benefits of iART. Survey respondents more commonly reported medication starts within three to four days of a reactive rapid HIV test rather than same-day initiation. Among survey respondents, compared to medical staff, non-medical staff were more likely to agree that medication should only be initiated after receiving confirmatory HIV test results (OR: 0.2, 95% CI: 0.06-0.8). Additionally, survey respondents from clinics serving a majority people of color were less likely to report iART on the same day as a reactive rapid HIV test (OR: 0.2, 95% CI: 0.02-1.0, p-value < 0.5). IDI results elucidated barriers to implementation, including perceived patient readiness, which potentially leads to added disparities in iART access.

CONCLUSION

iART has proven benefits and support for its implementation among HIV clinic staff. Our findings indicate that barriers to expanding iART access may be overcome if implementation resources are allocated strategically, which can further progress towards health equity.

The impact of same-day antiretroviral therapy initiation on retention in care and clinical outcomes at four eThekwini clinics, KwaZulu-Natal, South Africa

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.

The Rapid interaction: a qualitative study of provider approaches to implementing Rapid ART

BACKGROUND

Offering antiretroviral therapy (ART) to patients directly following an HIV diagnosis ("Rapid ART") improves clinical outcomes and is feasible and acceptable for patients and providers. Despite this, implementation of Rapid ART is not yet standard practice in the USA. Structural-level implementation guidance is available, but research at the individual provider level that explores the patient-provider interaction itself remains scarce. The Consolidated Framework for Implementation Research (CFIR) provides a nuanced guide to investigating the less visible, more social elements of implementation like the knowledge and feelings of people, and the influences of culture and resources on individual approaches.

METHODS

We conducted a multi-site qualitative study, exploring intervention commonalities across three HIV clinic environments: an HIV primary care clinic; an HIV/STI testing, treatment, and prevention clinic; and a large federally qualified health center (FQHC). Qualitative data were gathered from 27 provider informants-Rapid ART program staff and clinicians-using an interview guide developed using the CFIR. An experienced qualitative team conducted a comprehensive thematic analysis and identified cross-cutting themes in how providers approach and engage in the Rapid interaction, as well as longer-form narratives from providers that describe more fully what this interaction looks like for them.

RESULTS

Three main themes represent the range and content of individual provider approaches to the Rapid interaction: (1) patient-centeredness; (2) emotional support and partnership; and (3) correcting misperceptions about HIV. Each theme encompassed both conceptual approaches to offering Rapid ART and concrete examples of messaging to the patient that providers used in the Rapid interaction. We describe and show examples of these themes, offer key take-aways for implementation, and provide expanded narratives of providers' personal approaches to the Rapid interaction.

CONCLUSIONS

Exploration of provider-level approaches to Rapid ART implementation, as carried out in the patient-provider Rapid interaction, contributes a critical layer of evidence for wider implementation. It is our hope that, together with existing research showing positive outcomes and core components of systems-level implementation, these findings add to an instructive body of findings that facilitates the implementation of Rapid ART as an enhanced model of HIV care.

Same-day testing with initiation of antiretroviral therapy or tuberculosis treatment versus standard care for persons presenting with tuberculosis symptoms at HIV diagnosis: A randomized open-label trial from Haiti

BACKGROUND

Same-day HIV testing and antiretroviral therapy (ART) initiation is being widely implemented. However, the optimal timing of ART among patients with tuberculosis (TB) symptoms is unknown. We hypothesized that same-day treatment (TB treatment for those diagnosed with TB; ART for those not diagnosed with TB) would be superior to standard care in this population.

METHODS AND FINDINGS

We conducted an open-label trial among adults with TB symptoms at initial HIV diagnosis at GHESKIO in Haiti; participants were recruited and randomized on the same day. Participants were randomized in a 1:1 ratio to same-day treatment (same-day TB testing with same-day TB treatment if TB diagnosed; same-day ART if TB not diagnosed) versus standard care (initiating TB treatment within 7 days and delaying ART to day 7 if TB not diagnosed). In both groups, ART was initiated 2 weeks after TB treatment. The primary outcome was retention in care with 48-week HIV-1 RNA <200 copies/mL, with intention to treat (ITT) analysis. From November 6, 2017 to January 16, 2020, 500 participants were randomized (250/group); the final study visit occurred on March 1, 2021. Baseline TB was diagnosed in 40 (16.0%) in the standard and 48 (19.2%) in the same-day group; all initiated TB treatment. In the standard group, 245 (98.0%) initiated ART at median of 9 days; 6 (2.4%) died, 15 (6.0%) missed the 48-week visit, and 229 (91.6%) attended the 48-week visit. Among all who were randomized, 220 (88.0%) received 48-week HIV-1 RNA testing; 168 had <200 copies/mL (among randomized: 67.2%; among tested: 76.4%). In the same-day group, 249 (99.6%) initiated ART at median of 0 days; 9 (3.6%) died, 23 (9.2%) missed the 48-week visit, and 218 (87.2%) attended the 48-week visit. Among all who were randomized, 211 (84.4%) received 48-week HIV-1 RNA; 152 had <200 copies/mL (among randomized: 60.8%; among tested: 72.0%). There was no difference between groups in the primary outcome (60.8% versus 67.2%; risk difference: -0.06; 95% CI [-0.15, 0.02]; p = 0.14). Two new grade 3 or 4 events were reported per group; none were judged to be related to the intervention. The main limitation of this study is that it was conducted at a single urban clinic, and the generalizability to other settings is uncertain.

CONCLUSIONS

In patients with TB symptoms at HIV diagnosis, we found that same-day treatment was not associated with superior retention and viral suppression. In this study, a short delay in ART initiation did not appear to compromise outcomes.

TRIAL REGISTRATION

This study is registered with ClinicalTrials.gov NCT03154320.

Trends and factors associated with initiation of HIV treatment among PLHIV in Jamaica, 2015-2019

INTRODUCTION

Jamaica did not achieve the UNAIDS 90-90-90 targets in 2020. This study aimed to examine trends and factors associated with uptake of HIV treatment among people living with HIV (PLHIV) in Jamaica and to assess the effectiveness of revised treatment guidelines.

METHODS

This secondary analysis used patient-level data from the National Treatment Service Information System. The baseline sample was 8147 PLHIV initiating anti-retroviral treatment (ART) between January 2015-December 2019. Descriptive statistics were used to summarize demographic and clinical variables and the primary outcome timing of ART initiation. Multivariable logistic regression was used to assess factors associated with ART initiation (same day vs 31+ days), using categorical variables for age group, sex and regional health authority. Adjusted odds ratios and 95% confidence intervals are reported.

RESULTS

Most persons initiated ART at 31+ days (n = 3666, 45%) after the first clinic date or on the same day (n = 3461, 43%). Same day ART initiation increased from 37% to 51% over 5 years and was significantly associated with males (aOR = 0.82, CI = 0.74-0.92), 2018 (aOR = 0.66, CI = 0.56-0.77), 2019 (aOR = 0.77, CI = 0.65-0.92). late HIV diagnosis (aOR = 0.3, CI = 0.27-0.33) and viral suppression at the first viral load test (aOR = 0.6, CI = 0.53-0.67). ART initiation at 31+days was associated with 2015 (aOR = 1.21, CI = 1.01-1.45) and 2016 (aOR = 1.30, CI = 1.10-1.53) compared to 2017.

CONCLUSION

Our study shows that same day ART initiation increased between 2015-2019, however it remains too low. Same day initiation was associated with the years after Treat All implementation and late initiation before Treat All, providing evidence of the strategy's success. In order to achieve the UNAIDS targets, there is a need to also increase the number of diagnosed PLHIV retained on treatment in Jamaica. Further studies should be conducted to understand important challenges to accessing treatment as well as differentiated care models to improve treatment uptake and retention.

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.

Comparison of Immunological and Virological Recovery with Rapid, Early, and Late Start of Antiretroviral Treatment in Naive Plwh: Real-World Data

Background

Rapid initiation of antiretroviral therapy (ART) reduces the transmission of HIV infection in the community. This study aimed to determine whether rapid ART initiation is effective compared to standard ART treatment in our country.

Methods

Patients were grouped based on time to treatment initiation. HIV RNA levels, CD+4 T cell count, CD4/CD8 ratio, and ART regimens were recorded at baseline and follow-up visits for 12 months.

Results

There were 368-ART naive adults (treatment initiated at the time of HIV diagnosis; 143 on the first day, 48 on the second-seventh day, and 177 after the seventh day). Although virological suppression rates at 12^th months were higher in all groups, over 90% on average, there were no statistically significant differences in HIV-1 RNA suppression rates, CD+4 T cell count, and CD4/CD8 ratio normalization in the studied months but in multivariate logistic regression analysis; showed a significant correlation between both virological and immunological response and those with CD4+ T <350 cells/mL at 12th month in total patients.

Conclusion

Our findings support the broader application of recommendations for rapid ART initiation in HIV patients.

Longitudinal impact of compliance with routine CD4 monitoring on all cause deaths among treated people with HIV in China

Keeping adherence to the continuous and standardized CD4 follow-up monitoring service is of great significance to the control of disease progression and the reduction of avoidable mortality for HIV-infected patients. As non-communicable diseases (NCDs) have become main causes of deaths for people with HIV (PWH) in the era of combination antiretroviral therapy (cART), how and to what extent does adherence to routine CD4 monitoring differentially impact on AIDS-related versus NCDs-related deaths in low- and middle-income countries (LMIC) remains elucidated. A CD4 test index was developed by dividing the actual number of received CD4 tests by the theoretical number of CD4 tests that should have been performed according to national treatment guidelines during the study period, with an index value of 0.8-1.2 reflecting compliance. From 1989 to 2020, 14,571 adults were diagnosed with HIV infection in Dehong Prefecture of Yunnan province in Southwestern China, 6,683 (45.9%) PWH had died with the all-cause mortality of 550.13 per 10,000 person-years, including 3,250 (48.6%) AIDS-related deaths (267.53 per 10,000 person-years). Among patients on cART, the median CD4 test index was 1.0 (IQR 0.6-1.3), and 35.2% had a CD4 test index less than 0.8. Cox proportional hazards regression analysis indicated that PWH with CD4 test index at 0.8-1.2 were at the lowest risk of both AIDS-related (aHR = 0.06; 95%CI: 0.05-0.07) and NCDs-related (aHR = 0.13; 95%CI: 0.11-0.16)deaths. Adherence to routine CD4 monitoring is critical for reducing both AIDS-related and NCDs-related mortality of PWH. An appropriate (once or twice a year) rather than an unnecessarily higher frequency of routine CD4 testing could be most cost-effective in reducing mortality in LMIC.

Study protocol: A randomised trial of the effectiveness of the Common Elements Treatment Approach (CETA) for improving HIV treatment outcomes among women experiencing intimate partner violence in South Africa

INTRODUCTION

Intimate partner violence (IPV) is a barrier to consistent HIV treatment in South Africa. Previous trials have established that the Common Elements Treatment Approach (CETA), a cognitive-behavioural-based intervention, is effective in reducing mental and behavioural health problems but has not been trialled for effectiveness in improving HIV outcomes. This paper describes the protocol for a randomised trial that is testing the effectiveness of CETA in improving HIV treatment outcomes among women experiencing IPV in South Africa.

METHODS AND ANALYSIS

We are conducting a randomised trial among HIV-infected women on antiretroviral therapy, who have experienced sexual and/or physical IPV, to test the effect of CETA on increasing retention and viral suppression and reducing IPV. Women living with HIV who have an unsuppressed viral load or are at high risk for poor adherence and report experiencing recent IPV, defined as at least once within in the last 12 months, will be recruited from HIV clinics and randomised 1:1 to receive CETA or an active attention control (text message reminders). All participants will be followed for 24 months. Follow-up HIV data will be collected passively using routinely collected medical records. HIV outcomes will be assessed at 12 and 24 months post-baseline. Questionnaires on violence, substance use and mental health will be administered at baseline, post-CETA completion and at 12 months post-baseline. Our primary outcome is retention and viral suppression (<50 copies/mL) by 12 months post-baseline. We will include 400 women which will give us 80% power to detect an absolute 21% difference between arms. Our primary analysis will be an intention-to-treat comparison of intervention and control by risk differences with 95% CIs.

Uptake and effect of universal test-and-treat on twelve months retention and initial virologic suppression in routine HIV program in Kenya

Early combination antiretroviral therapy (cART), as recommended in WHO's universal test-and-treat (UTT) policy, is associated with improved linkage to care, retention, and virologic suppression in controlled studies. We aimed to describe UTT uptake and effect on twelve-month non-retention and initial virologic non-suppression (VnS) among HIV infected adults starting cART in routine HIV program in Kenya. Individual-level HIV service delivery data from 38 health facilities, each representing 38 of the 47 counties in Kenya were analysed. Adults (>15 years) initiating cART between the second-half of 2015 (2015HY2) and the first-half of 2018 (2018HY1) were followed up for twelve months. UTT was defined based on time from an HIV diagnosis to cART initiation and was categorized as same-day, 1-14 days, 15-90 days, and 91+ days. Non-retention was defined as individuals lost-to-follow-up or reported dead by the end of the follow up period. Initial VnS was defined based on the first available viral load test with >400 copies/ml. Hierarchical mixed-effects survival and generalised linear regression models were used to assess the effect of UTT on non-retention and VnS, respectively. Of 8592 individuals analysed, majority (n = 5864 [68.2%]) were female. Same-day HIV diagnosis and cART initiation increased from 15.3% (2015HY2) to 52.2% (2018HY1). The overall non-retention rate was 2.8 (95% CI: 2.6-2.9) per 100 person-months. When compared to individuals initiated cART 91+ days after a HIV diagnosis, those initiated cART on the same day of a HIV diagnosis had the highest rate of non-retention (same-day vs. 91+ days; aHR, 1.7 [95% CI: 1.5-2.0], p<0.001). Of those included in the analysis, 5986 (69.6%) had a first viral load test done at a median of 6.3 (IQR, 5.6-7.6) months after cART initiation. Of these, 835 (13.9%) had VnS. There was no association between UTT and VnS (same-day vs. 91+ days; aRR, 1.0 [95% CI: 0.9-1.2], p = 0.664). Our findings demonstrate substantial uptake of the UTT policy but poor twelve-month retention and lack of an association with initial VnS from routine HIV settings in Kenya. These findings warrant consideration for multi-pronged program interventions alongside UTT policy for maximum intended benefits in Kenya.

Using nominal group technique to identify barriers and facilitators to preventing HIV using combination same-day pre-exposure prophylaxis and medications for opioid use disorder

BACKGROUND

Preventing HIV transmission among people who inject drugs (PWID) is a key element of the US Ending the HIV Epidemic strategy and includes both pre-exposure prophylaxis (PrEP) and medications for opioid use disorder (MOUD). While both lead to decreases in HIV transmission, MOUD has other social and health benefits; meanwhile, PrEP has additional HIV prevention advantages from sexual risk and the injection of stimulants. However, these medications are often prescribed in different settings and require multiple visits before initiation. Strategies to integrate these services (i.e., co-prescription) and offer same-day prescriptions may reduce demands on patients who could benefit from them.

METHODS

Nominal group technique, a consensus method that rapidly generates and ranks responses, was used to ascertain barriers and solutions for same-day delivery of PrEP and MOUD as an integrated approach among PWID (n = 14) and clinical (n = 9) stakeholders. The qualitative portion of the discussion generated themes for analysis, and the ranks of the proposed barriers and solutions to the program are presented.

RESULTS

The top three barriers among PWID to getting a same-day prescription for both PrEP and MOUD were (1) instability of insurance (e.g., insurance lapses); (2) access to a local prescriber; and (3) client-level implementation factors, such as lack of personal motivation. Among clinical stakeholders, the three greatest challenges were (1) time constraints on providers; (2) logistics (e.g., coordination between providers and labs); and (3) availability of providers who can prescribe both medications. Potential solutions identified by both stakeholders included pharmacy delivery of the medications, coordinated care between providers and health care systems (e.g., case management), and efficiencies in clinical care (e.g., clinical checklists), among others.

CONCLUSIONS

Implementing and sustaining a combined PrEP and MOUD strategy will require co-training providers on both medications while creating efficiencies in systems of care and innovations that encourage and retain PWID in care. Pilot testing the co-prescribing of PrEP and MOUD with quality performance improvement is a step toward new practice models.

Antiretroviral therapy initiation within 7 and 8-30 days post-HIV diagnosis demonstrates similar benefits in resource-limited settings

We estimated the optimum time to initiate antiretroviral therapy (ART) in a retrospective observational cohort. We observed that ART initiation 7 days or less ( n  = 817) and 8-30 days ( n  = 1009) were the most important factors with viral suppression, and had similar viral suppression rate, CD4 + T-cell count increase and fractions of individuals with links at least 4 and individuals linked to recent HIV infection in HIV molecular networks. This study provides real-world evidence on the benefits of rapid ART initiation in resource-limited setting.

"I am alive because of her": factors affecting adherence to combination antiretroviral therapy among people living with HIV in KwaZulu-Natal, South Africa

BACKGROUND

People living with HIV need to take lifelong, combination antiretroviral therapy (cART), but there have been only limited explorations of how factors affecting adherence can change over the course of an individual's lifetime.

METHODS

We carried out a qualitative study of men and women living with HIV in KwaZulu, Natal, South Africa who were prescribed cART and who had periods of higher and lower adherence.

RESULTS

18 individuals participated in open-ended interviews. Using a dynamic theory of adherence, we identified factual, relational, and experiential factors that were associated with adherence and non-adherence to cART. Periods of non-adherence were commonly reported. Participants described relationships and experiences as being important influences on their ability to adhere to cART throughout their treatment journeys.

CONCLUSIONS

Periods of non-adherence to cART are common. While many cART counseling models are based on conveying facts to people prescribed cART, providing opportunities for supportive relationship where people can process their varied experiences is likely important to maintaining health for people living with HIV.

Study on the Mechanism of Improving HIV/AIDS Immune Function with Jian Aikang Concentrated Pill Based on Network Pharmacology Combined with Experimental Validation

Purpose

This study was the first to screen the active compounds of Jian Aikang Concentrated Pill (JAKCP) with network pharmacology, predict its potential targets, screen the signaling pathways, and combine with cellular experimental validation to explore the potential mechanism of JAKCP for the treatment of acquired immunodeficiency syndrome (AIDS).

Methods

The main compounds and targets of Chinese herbs in JAKCP were identified by TCMSP; the targets of AIDS were collected from Genecards, Online Mendelian Inheritance in Man (OMIM), Disgenet, Therapeutic Target Database (TTD) and Drugbank; the network of “Chinese herbs-active compounds-targets” for JAKCP was constructed by Cytoscape, and protein–protein interaction (PPI) network was constructed using STRING to generate the intersection targets, Metascape was conducted to analyze the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), and the network of “main active compounds-core targets-pathways” was constructed by Cytoscape. Finally, the effect of JAKCP on the survival rate of HIV pseudovirus-infected MT-4 cells was investigated by CCK-8 assay, and the predicted targets were verified by ELISA, qPCR and Western blot.

Results

A total of 147 active compounds of JAKCP were screened covering 351 targets and 416 AIDS disease targets were obtained, besides 140 intersection targets and 321 KEGG pathways were collected. Ultimately, quercetin, kaempferol, stigmasterol, beta-sitosterol, epigallocatechin gallate were identified as the important compounds, the core targets are HSP90AA1, IL-10, IL-6, TNF, IL-1β, TP53, and IL-1ɑ, and the biological pathways and processes mainly include T cell activation, regulation of DNA-binding transcription factor activity and apoptotic signaling pathway. Experiments on the targets of “T cell activation” demonstrated that JAKCP promotes the survival of HIV pseudovirus-infected MT-4 cells. Also, JAKCP down-regulated mRNA and protein levels of IL-1ɑ, IL-1β, and IL-6 while up-regulated mRNA and protein levels of IL-2, IL-6ST, and IL-10 in vitro.

Conclusion

JAKCP exerted regulatory immune functions through multi-component, multi-target and multi-pathway, thereby providing novel ideas and clues for the treatment of AIDS.

Multilevel Determinants of Rapid Antiretroviral Treatment Implementation and Demand in Miami-Dade County

BACKGROUND

Rapidly linking newly diagnosed HIV patients to antiretroviral treatment (ART) is the best practice for achieving optimal treatment outcomes, including viral suppression. However, rapid ART implementation varies throughout the United States, highlighting the importance of identifying rapid ART implementation determinants in US HIV epicenters, such as Miami-Dade County (MDC).

METHODS

Clinic focus groups (N = 4 clinics) and patient interviews (N = 31 recently diagnosed patients) systematically and qualitatively assessed rapid ART implementation determinants in MDC. Independent coders analyzed focus groups and interviews using a directed content analysis approach guided by the Consolidated Framework for Implementation Research.

RESULTS

For clinic stakeholders, key rapid ART implementation determinants included the following: complexity and adaptability (innovation characteristics); networks between clinics and patient needs rooted in structural inequities (outer setting); leadership and available resources (inner setting); staff/provider flexibility (characteristics of individuals); and appointing patient navigators and champions (process). For patients, key determinants included complexity and relative advantage of rapid treatment (innovation characteristics); patient needs and clinic networks (outer setting); provider knowledge and skills (inner setting); provider warmth and affirmation (characteristics of individuals); and need for improved outreach (process).

CONCLUSIONS

Multilevel factors impact clinic implementation and patient demand for rapid ART in MDC. Informed by these factors, we identified potential implementation strategies to enhance rapid ART implementation throughout MDC. These implementation strategies can be tested in an implementation trial, enhancing the toolkit of strategies to ensure that evidence-based tools, particularly rapid ART, are readily available to the most impacted communities.

Simplified clinical algorithm for immediate antiretroviral therapy initiation: The HATI [HIV awal (early) Test & Treat in Indonesia] implementation research in Indonesia

Background & objectives

Although the World Health Organization recommends same day or rapid (< seven days) antiretroviral therapy (ART) initiation, delays in ART initiation remain common due to waiting for laboratory test results. This study employed a simplified clinical algorithm the HATI [HIV Awal (Early) Test & Treat Indonesia]-SAI (Simple ART Initiation) aimed to increase the proportion of ART uptake and decrease the time to ART initiation that can be used in various care settings.

Methods

This study compared the percentage of ART uptake and retention, viral load (VL) suppression and time to ART initiation between the observation and intervention phases among newly diagnosed HIV patients from key populations. As part of the intervention, the newly diagnosed patients underwent screening using a simple form [consisting of data on age, height and weight (for body mass index calculation), questions on the presence of symptoms of HIV stages 1 and 2, tuberculosis, history of diabetes, hypertension and kidney disease], to determine eligibility for immediate ART initiation. Those who met the pre-defined criteria immediately received a combination of tenofovir lamivudine and efavirenz for two weeks. The baseline laboratory examination due to this was moved up to two weeks post ART. Factors significantly associated with ART uptake were also determined and their odds ratios were measured using logistic regression analysis.

Results

A total of 2173 people newly diagnosed with HIV were recruited, with 1579 and 594 in the observation and intervention phases, respectively. In both phases, the majority were men who have sex with men, who were young (<30 yr old) and employed, with high levels of education. The intervention phase significantly increased the proportion of ART initiation [91%, 95% confidence interval (CI): 89-93% vs. 78%, 95% CI: 76-80%] but did not have any impact on the proportion of six months retention and VL suppression. The intervention also significantly decreased the time to ART initiation from median ± interquartile range: 9±20 days to 2±10 days.

Interpretation & conclusions

The findings of this study suggest that the HATI-SAI intervention increased the uptake and decreased the time for immediate ART initiation. The HATI-SAI provides a simple and safe clinical approach that can readily be adopted in different settings without a costly investment in technology.

Evaluation of peer-to-peer HIV counseling in Myanmar: a measure of knowledge, adherence, and barriers

In Myanmar, an Asian country with one of the highest HIV-1 prevalence rates, counseling prior to initiating antiretroviral therapy (ART) is standard care, either by a healthcare worker (standard counselor, SC) or trained counselor who is also living with HIV (peer counselor, PC). PC is commonly utilized in Myanmar and other resource-limited settings. However, its benefit over SC is unclear. We conducted a cross-sectional survey of people living with HIV (PLWH), who completed either only PC or only SC before treatment initiation across four cities in Myanmar. Participants were evaluated for HIV knowledge, stigma, antiretroviral adherence, barriers to care, social support satisfaction and attitudes regarding both counseling processes. Bivariate analyses and multivariable mixed effects modeling were conducted to compare differences in these measures among PC and SC participants. Among 1006 participants (49% PC; 51% SC), 52% were females and median age was 37 years in those receiving PC and 40 years in those receiving SC. More than 70% of participants in both groups achieved up to grade school education. The average duration since HIV diagnosis was 4.6 years for PC and 5.7 years for SC participants. HIV knowledge and attitudes regarding counseling were good in both groups and more PC participants credited their HIV counselor for knowledge (75% vs 63%, p < 0.001). Compared to SC, PC participants had lower enacted stigma (Incidence Rate Ratio (IRR) 0.75, Confidence Interval (CI) [0.65, 0.86]), mean internalized stigma (-0.24, CI [-0.34, -0.14]), and risk of antiretroviral therapy non-adherence (Odds Ratio 0.59, CI [0.40, 0.88]), while reporting higher levels of barriers to care (9.63, CI [8.20, 11.75]). Our findings demonstrate potential benefits of PC compared to SC, and support the utilization of PC to enhance HIV health outcomes within the unique societal and geographical context of Myanmar, and possibly beyond.

Study protocol of a randomized controlled trial comparing two linkage models for HIV prevention and treatment in justice-involved persons

Background

Persons involved in the justice system are at high risk for HIV and drug overdose upon release to the community. This manuscript describes a randomized controlled trial of two evidence-based linkage interventions for provision of HIV prevention and treatment and substance use disorder (SUD) services in four high risk communities to assess which is more effective at addressing these needs upon reentry to the community from the justice system.

Methods

This is a 5-year hybrid type 1 effectiveness-implementation randomized controlled trial that compares two models (Patient Navigation [PN] or Mobile Health Unit [MHU] service delivery) of linking justice-involved individuals to the continuum of community-based HIV and SUD prevention and treatment service cascades of care. A total of 864 justice-involved individuals in four US communities with pre-arrest histories of opioid and/or stimulant use who are living with or at-risk of HIV will be randomized to receive either: (a) PN, wherein patient navigators will link study participants to community-based service providers; or (b) services delivered via an MHU, wherein study participants will be provided integrated HIV prevention/ treatment services and SUD services. The six-month post-release intervention will focus on access to pre-exposure prophylaxis (PrEP) for those without HIV and antiretroviral treatment (ART) for people living with HIV (PLH). Secondary outcomes will examine the continuum of PrEP and HIV care, including: HIV viral load, PrEP/ ART adherence; HIV risk behaviors; HCV testing and linkage to treatment; and sexually transmitted infection incidence and treatment. Additionally, opioid and other substance use disorder diagnoses, prescription, receipt, and retention on medication for opioid use disorder; opioid and stimulant use; and overdose will also be assessed. Primary implementation outcomes include feasibility, acceptability, sustainability, and costs required to implement and sustain the approaches as well as to scale-up in additional communities.

Discussion

Results from this project will help inform future methods of delivery of prevention, testing, and treatment of HIV, HCV, substance use disorders (particularly for opioids and stimulants), and sexually transmitted infections for justice-involved individuals in the community.

Essential elements of and challenges to rapid ART implementation: a qualitative study of three programs in the United States

BACKGROUND

Antiretroviral therapy (ART) initiation on the day of an HIV diagnosis or as soon as possible after diagnosis, known as rapid ART (henceforth "RAPID"), is considered to be a safe and effective intervention to quickly reduce viral load and potentially improve engagement in care over time. However, implementation of RAPID programming is not yet widespread. To facilitate broader dissemination of RAPID, we sought to understand health care worker experiences with RAPID implementation and to identify essential programmatic elements.

METHODS

We conducted 27 key informant interviews with medical providers and staff involved in RAPID service delivery in three distinct clinical settings: an HIV clinic, a Federally Qualified Health Center and a sexual health and wellness clinic. Interviews were structured around domains associated with the Consolidated Framework for Implementation Research and were audio-recorded, transcribed, and thematically analyzed.

FINDINGS

We identified seven (7) essential elements across settings associated with successful RAPID program implementation. These high-impact elements represent essential components without which a RAPID program could not function. There was no one requisite formation. Instead, we observed a constellation of essential elements that could be operationalized in various formations and by various people in various roles. The essential elements included: (1) presence of an implementation champion; (2) comfort and competence prescribing RAPID ART; (3) expedited access to ART medications; (4) expertise in benefits, linkage, and care navigation; (5) RAPID team member flexibility and organizations' adaptive capacity; (6) patient-centered approach; and (7) strong communication methods and culture.

CONCLUSIONS

The RAPID model can be applied to a diverse range of clinical contexts. The operational structure of RAPID programs is shaped by the clinical setting in which they function, and therefore the essential elements identified may not apply equally to all programs. Based on the seven essential elements described above we recommend future implementers identify where these elements currently exist within a practice; leverage them when possible; strengthen them when necessary or develop them if they do not yet exist; and look to these elements when challenges arise for potential solutions.

Early versus delayed antiretroviral therapy based on genotypic resistance test: Results from a large retrospective cohort study

Rapid start of antiretroviral therapy (ART) pending genotypic resistance test (GRT) has been recently proposed, but the effectiveness of this strategy is still debated. The rate of virological success (VS), defined as HIV‐RNA < 50 copies/ml, with and without GRT was compared in drug‐naïve individuals enrolled in the Italian ARCA cohort who started ART between 2015 and 2018. 521 individuals started ART: 397 without GRT (pre‐GRT group) and 124 following GRT (post‐GRT group). Overall, 398 (76%) were males and 30 (6%) were diagnosed with AIDS. In the pre‐GRT group, baseline CD4+ cell counts were lower (p < 0.001), and viral load was higher (p < 0.001) than in the post‐GRT group. The estimated probability of VS in pre‐GRT versus post‐GRT group was 72.54% (CI₉₅: 67.78–76.60) versus 66.94% (CI₉₅: 57.53–74.26) at Week 24 and 92.40% (CI₉₅: 89.26–94.62) versus 92.92% (CI₉₅: 86.35–96.33) at Week 48, respectively (p = 0.434). At Week 48, VS was less frequent among individuals with baseline CD4+ cell counts <200 versus >500 (90.33% vs. 97.33%), log viral load <5.00 versus >5.70 log₁₀ cps/ml (97.17% vs 78.16%; p < 0.001), and those treated with protease inhibitors or non‐nucleoside reverse transcriptase inhibitors versus those treated with integrase strand transfer inhibitors (p < 0.001). The rate of VS does not seem to be affected by an early ART initiation pending GRT results, but it could be influenced by the composition of the ART regimen, as well as immuno‐virological parameters.
