RESUMEN

BACKGROUND: Numerous studies in South Africa have reported low HIV viral load (VL) suppression and high attrition rates within the pediatric HIV treatment program. OBJECTIVE: Using routine laboratory data, we evaluated HIV VL monitoring, including mobility and overdue VL (OVL) testing, within 5 priority districts in South Africa. METHODS: We performed a retrospective descriptive analysis of National Health Laboratory Service (NHLS) data for children and adolescents aged 1-15 years having undergone HIV VL testing between May 1, 2019, and April 30, 2020, from 152 facilities within the City of Johannesburg, City of Tshwane, eThekwini, uMgungundlovu, and Zululand. HIV VL test-level data were deduplicated to patient-level data using the NHLS CDW (Corporate Data Warehouse) probabilistic record-linking algorithm and then further manually deduplicated. An OVL was defined as no subsequent VL determined within 18 months of the last test. Variables associated with the last VL test, including age, sex, VL findings, district type, and facility type, are described. A multivariate logistic regression analysis was performed to identify variables associated with an OVL test. RESULTS: Among 21,338 children and adolescents aged 1-15 years who had an HIV VL test, 72.70% (n=15,512) had a follow-up VL test within 18 months. Furthermore, 13.33% (n=2194) of them were followed up at a different facility, of whom 3.79% (n=624) were in a different district and 1.71% (n=281) were in a different province. Among patients with a VL of ≥1000 RNA copies/mL of plasma, the median time to subsequent testing was 6 (IQR 4-10) months. The younger the age of the patient, the greater the proportion with an OVL, ranging from a peak of 52% among 1-year-olds to a trough of 21% among 14-year-olds. On multivariate analysis, 2 consecutive HIV VL findings of ≥1000 RNA copies/mL of plasma were associated with an increased adjusted odds ratio (AOR) of having an OVL (AOR 2.07, 95% CI 1.71-2.51). Conversely, patients examined at a hospital (AOR 0.86, 95% CI 0.77-0.96), those with ≥2 previous tests (AOR 0.78, 95% CI 0.70-0.86), those examined in a rural district (AOR 0.63, 95% CI 0.54-0.73), and older age groups of 5-9 years (AOR 0.56, 95% CI 0.47-0.65) and 10-14 years (AOR 0.51, 95% CI 0.44-0.59) compared to 1-4 years were associated with a significantly decreased odds of having an OVL test. CONCLUSIONS: Considerable attrition occurs within South Africa's pediatric HIV treatment program, with over one-fourth of children having an OVL test 18 months subsequent to their previous test. In particular, younger children and those with virological failure were found to be at increased risk of having an OVL test. Improved HIV VL monitoring is essential for improving outcomes within South Africa's pediatric antiretroviral treatment program.

RESUMEN

Ribonuclease H (RNase H) was identified as an important target for HIV therapy. Currently, no RNase H inhibitors have reached clinical status. Herein, a series of novel thiazolone[3,2-a]pyrimidine-containing RNase H inhibitors were developed, based on the hit compound 10i, identified from screening our in-house compound library. Some of these derivatives exhibited low micromolar inhibitory activity. Among them, compound 12b was identified as the most potent inhibitor of RNase H (IC50 = 2.98 µM). The experiment of magnesium ion coordination was performed to verify that this ligand could coordinate with magnesium ions, indicating its binding ability to the catalytic site of RNase H. Docking studies revealed the main interactions of this ligand with RNase H. A quantitative structure activity relationship (QSAR) was also conducted to disclose several predictive mathematic models. A molecular dynamics simulation was also conducted to determine the stability of the complex. Taken together, thiazolone[3,2-a]pyrimidine can be regarded as a potential scaffold for the further development of RNase H inhibitors.

RESUMEN

BACKGROUND: HIV-associated tuberculosis (TB) contributes disproportionately to global tuberculosis mortality. Patients hospitalised at the time of the diagnosis of HIV-associated disseminated TB are typically severely ill and have a high mortality risk despite initiation of tuberculosis treatment. The objective of the study is to assess the safety and efficacy of both intensified TB treatment (high dose rifampicin plus levofloxacin) and immunomodulation with corticosteroids as interventions to reduce early mortality in hospitalised patients with HIV-associated disseminated TB. METHODS: This is a phase III randomised controlled superiority trial, evaluating two interventions in a 2 × 2 factorial design: (1) high dose rifampicin (35 mg/kg/day) plus levofloxacin added to standard TB treatment for the first 14 days versus standard tuberculosis treatment and (2) adjunctive corticosteroids (prednisone 1.5 mg/kg/day) versus identical placebo for the first 14 days of TB treatment. The study population is HIV-positive patients diagnosed with disseminated TB (defined as being positive by at least one of the following assays: urine Alere LAM, urine Xpert MTB/RIF Ultra or blood Xpert MTB/RIF Ultra) during a hospital admission. The primary endpoint is all-cause mortality at 12 weeks comparing, first, patients receiving intensified TB treatment to standard of care and, second, patients receiving corticosteroids to those receiving placebo. Analysis of the primary endpoint will be by intention to treat. Secondary endpoints include all-cause mortality at 2 and 24 weeks. Safety and tolerability endpoints include hepatoxicity evaluations and corticosteroid-related adverse events. DISCUSSION: Disseminated TB is characterised by a high mycobacterial load and patients are often critically ill at presentation, with features of sepsis, which carries a high mortality risk. Interventions that reduce this high mycobacterial load or modulate associated immune activation could potentially reduce mortality. If found to be safe and effective, the interventions being evaluated in this trial could be easily implemented in clinical practice. TRIAL REGISTRATION: ClinicalTrials.gov NCT04951986.

RESUMEN

Internalized stigma, a condition characterized by negative self-stereotyping and social alienation, recently impacted the adolescents and young adults living with HIV (AYLHIV) epidemic curve and treatment adherence. While prior research has focused on the impact of internalized stigma among adults living with HIV, few studies focused on this AYLHIV. The study aims to determine internalized stigma proportion and its relationship to HIV viral suppression in AYLHIV. A cross-sectional study involved 93 fully disclosed AYLHIV receiving HIV care in Faith Alive Foundation in Jos North, Plateau State, from January to March 2023. Internalized stigma was measured using the adapted Berger HIV Stigma Scale under the domains personalized stigma (18 item questions) and negative self-image subscales (13 item questions), measured on a 4-scale of strongly disagree (1), disagree (2), agree (3), and strongly agree (4). Scores summed up to give the domain composite score with a maximum obtainable score of 72 for personalized stigma and 52 for negative self-image. A total of 93 respondents, female-63 (68%) and male-30 (32%), were involved in the study and their mean age at full disclosure was 15.7 ± 2.8 years. During the study their mean age was 19.5 ± 5.4 years, with 62% (58) ages 10-19 years and 38% (35) ages 20-26 years. Furthermore, 70% of the participants had secondary educational status, 77% had viral load results <1000 copies/ml), and 57% were on ART for up to 6 years. The average scores for personalized and negative self-image were 36.3 and 28.9, with 53% (49/93) and 52% (48/93) scoring higher than the average respectively. Further subclassification of the participants by the presence of internalized stigma domains reported 62% (58/93) with both domains, 20% (19/93) with at least one domain, and 38% (35/93) with none of the domains. Negative self-image stigma was reported more among participants 10-19 years (63%), male (31%), of secondary educational level (71%), virally unsuppressed (23%), and ≤ 6 years on ART (42%). On the other hand, personalized stigma was more among the female participants (73%), ages 20-29 years (41%), educational level (6% and 27% had primary and tertiary level of education respectively), virally suppressed (80%), and up to 6 years on ART (63%). The correlation between the internalized stigma domains and suppressed viral load using a binary multivariate regression method at 95% CI and a p-value of 0.05 was not statistically significant with personalized stigma (p = 0.73) and negative self-image (p = 0.92). The adjusted odds ratio of having internalized stigma among the virally suppressed were personalized stigmas [OR; 1.21, 95% CI; 0.42-3.47] and that of negative self-image [OR; 1.06, 95% CI; 0.38-2.95]. This study showed a high proportion of internalized stigma among females, ages 10-19 years, and virally suppressed with more odds for personalized stigma domain. However, the study reported no statistically significant association between internalized stigma domains and viral suppression.

RESUMEN

BACKGROUND: For those HIV seropositive people with high viral loads, the World Health Organization recommends more counseling before changing ART regimens. A high viral load can lead to increased HIV transmission and lower survival rates. Clients with viral loads above 1000 copies/mL should receive enhanced adherence counseling for 3-6 months before switching. Despite enhanced adherence counseling programs, most countries struggle with viral load suppression. Little is known about viral load suppression in Ethiopia and the research area after counseling. OBJECTIVE: This study aims to assess viral load suppression and its predictors among HIV-positive individuals receiving enhanced adherence counseling in Bahir Dar, Northwest Ethiopia, in 2022. METHODS: An institution-based retrospective follow-up study was conducted among randomly selected 546 clients on Enhanced Adherence Counseling at public health facilities in Bahir Dar city. The Epicollect5 mobile application was used to collect the data, which was then exported to Stata version 14 for analysis. A Log-Binomial regression model was fitted for each explanatory variable. Variables having a p-value <0.25 in bivariate analysis were entered into a multivariable Log-Binomial regression model. Finally, an adjusted risk ratio with a 95% confidence interval and a p-value <0.05 was used to measure the strength of the prediction. RESULTS: Following enhanced adherence counseling, 312 (57.1%) people had their viral load suppressed. Absence of recurrent OI (ARR 1.40; CI 1.03-1.91), EAC stay less than 3 months (ARR 1.54; CI 1.19-1.99), EAC stay 3-6 months (ARR 1.38; CI 1.12-1.69), once-daily ARV dose regimen (ARR 1.28; CI 1.03-1.58), baseline viral load of 2879.00 copies/ml (ARR 1.30, CI 1.06-1.60), being orthodox Tewahido Christian (ARR 0.37; CI 0.18-0.75) were significant predictors of viral load suppression after Enhanced Adherence Counseling. CONCLUSION AND RECOMMENDATION: Most importantly, this study found that most people had suppressed viral loads after receiving enhanced adherence counseling. Significant predictors of viral load suppression included recurrent OI, length of stay on EAC, daily ARV dosing regimen, baseline viral load, and religion. Clients with a high baseline viral load and those who experience recurring opportunistic infections should get extra care during EAC sessions.

RESUMEN

PURPOSE: To evaluate the real-world rates of non-adherence and non-persistence to antiretroviral therapy (ART) among treatment-naïve adult patients with HIV after a 12-month follow-up period in Belgium. METHODS: A retrospective analysis of longitudinal pharmacy claims was conducted using the Pharmanet database from January 1, 2018, to December 31, 2021. Non-adherence was assessed over 12 months and reported as the proportion of days covered below the 80% threshold. Non-persistence was defined as the first 90-day gap in treatment between the two types of ART dispensed. Poisson regression with robust standard error and Cox proportional hazard models were used to assess the factors associated with non-adherence and non-persistence, respectively. RESULTS: Overall, 2999 patients were initiated on ART between 2018 and 2021. After a 12-month follow-up, the proportions of non-adherence and non-persistence were 35.6% and 15.9%, respectively in 2018, and decreased to 18.7% and 6.8%, respectively in 2021. Non-adherence was higher among women, Brussels residents, and those receiving multiple-tablet regimens (MTRs). Similarly, the prevalence of non-persistence was higher among women and MTR recipients. CONCLUSION: Among treatment-naïve adults with HIV in Belgium, non-adherence, and non-persistence to ART showed improvement over the study period but remained at high levels. Disparities were observed by sex and between geographical regions. Prioritizing strategies targeting women in Brussels and facilitating the transition from MTRs to single-tablet regimens should be emphasized optimize adherence to ART in Belgium.

RESUMEN

Background: The COVID-19 pandemic has presented new challenges to adhering to ART, and its influence on adherence and related factors has not been thoroughly studied. This study examines ART adherence and its associated factors during the COVID-19 pandemic. Methods: A cross-sectional study was conducted on HIV-positive individuals receiving care and treatment in public health facilities. A total of 612 participants were selected using a multi-stage sampling procedure. Data were collected through interviewer-administered questionnaires and chart reviews. We used Epi-data for data entry and Stata for data analysis. Results: Good adherence to antiretroviral therapy in this study was 76.5% (95% CI, 72.9, 79.7). Divorced marital status (AOR = 0.45,95%CI:0.22,0.90), regular follow-up (AOR = 3.01,95%CI:1.81,5.01), adherence counseling and information in the context of COVID-19 pandemic (AOR = 2.57,95%CI:1.63,4.08), and knowledge about ART (AOR = 1.81,95%CI:1.11,2.94) were significantly associated with adherence to antiretroviral therapy. Conclusion: The observed adherence rate in this study was lower than the World Health Organization recommendation and previous studies. The study highlighted the importance of addressing adherence to ART among HIV-positive adults during the COVID-19 pandemic and other upcoming emerging and reemerging outbreaks. Strategies to improve adherence should consider factors such as marital status, regular follow-up, provision of counseling and information, and enhancing knowledge about ART.

RESUMEN

BACKGROUND: Screening for tuberculosis (TB) and providing TB preventive treatment (TPT) along with antiretroviral therapy is key components of human immune deficiency virus (HIV) care. The uptake of TPT during the coronavirus disease 2019 (COVID-19) period has not been adequately assessed in Addis Ababa City Administration. This study aimed at assessing TPT uptake status among People living with HIV (PLHIV) newly initiated on antiretroviral therapy during the COVID-19 period at all public hospitals of Addis Ababa City Administration, Ethiopia. METHODS: A retrospective data review was conducted from April-July 2022. Routine District Health Information System 2 database was reviewed for the period from April 2020-March 2022. Proportion and mean with standard deviation were computed. Logistic regression analysis was conducted to assess factors associated with TPT completion. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 1,069 PLHIV, aged 18 years and above were newly initiated on antiretroviral therapy, and of these 1,059 (99.1%) underwent screening for TB symptoms. Nine hundred twelve (86.1%) were negative for TB symptoms. Overall, 78.8% (719) of cases who were negative for TB symptoms were initiated on TPT, and of these 70.5% and 22.8% were completed and discontinued TPT, respectively. Of 719 cases who were initiated on TPT, 334 (46.5%) and 385 (53.5%) were initiated on isoniazid plus rifapentine weekly for three months and Isoniazid preventive therapy daily for six months, respectively. PLHIV who were initiated on isoniazid plus rifapentine weekly for three months were more likely to complete TPT (adjusted odds ratio [AOR],1.68; 95% confidence interval [CI], 1.01, 2.79) compared to those who were initiated on Isoniazid preventive therapy daily for six months. CONCLUSION: While the proportion of PLHIV screened for TB was high, TPT uptake was low and far below the national target of achieving 90% TPT coverage. Overall a considerable proportion of cases discontinued TPT in this study. Further strengthening of the programmatic management of latent TB infection among PLHIV is needed. Therefore, efforts should be made by the Addis Ababa City Administration Health Bureau authorities and program managers to strengthen the initiation and completion of TPT among PLHIV in public hospitals.

RESUMEN

The efficacy of 400mg efavirenz (EFV) once daily is reported to be similar to that of 600mg EFV. However, EFV-related toxic and side effects of 400mg EFV are significantly reduced. Here, the feasibility of reducing EFV to 400mg once a day in HIV-infected/AIDS patients was evaluated. Fifty patients were included. Patients were given 3TC+TDF+400mg EFV (n=25) or 3TC+TDF+600mg EFV (n=25). The proportion of patients with HIV RNA < 40 copies/mL and the adverse events served as the primary and secondary outcomes, respectively. HIV inhibition rates of the 3TC+TDF+400mg EFV group and 3TC+TDF+600mg EFV group were both 56.52% at week 24 and respectively 100%, 91.3% at week 48. During 48 weeks, 27 cases of adverse events were reported in the 3TC+TDF+400mg EFV group, lower than those in the 3TC+TDF+600mg EFV group, which had 39 cases. Compared with the 3TC+TDF+400mg EFV group, the incidence of transaminase, dizziness, hyperlipidemia and rashes all increased in the 3TC+TDF+600mg EFV group (P>0.05). No serious adverse events of the central nervous system occurred. The incidence of depression, sleep disturbance, and vertigo were similar (P>0.05). The efficacy of 400mg EFV is comparable to 600mg EFV. However, patients receiving 400mg EFV have fewer adverse events.

RESUMEN

BACKGROUND: Understanding factors associated with antiretroviral treatment (ART) adherence is crucial for ART success among people living with HIV (PLHIV) in the "test and treat" era. Multiple psychosocial factors tend to coexist and have a syndemic effect on ART adherence. We aimed to explore factors associated with ART adherence and the syndemic effect of multiple psychosocial factors on ART adherence among PLHIV newly starting ART in Guangdong Province, China. METHODS: Newly diagnosed PLHIV from six cities in Guangdong Province were recruited between May 2018 and June 2019, and then followed up from May 2019 to August 2020. Baseline and follow-up data were collected from a questionnaire and the national HIV surveillance system, the follow-up data of which were analyzed in this study. A Center for Adherence Support Evaluation (CASE) index > 10 points was defined as optimal ART adherence, which was measured via participants' self-reported adherence during follow-up survey. Multivariable logistic regression was used to identify factors associated with ART adherence. Exploratory factor analysis (EFA) and multi-order latent variable structural equation modeling (SEM) were performed to explore the syndemic effect of multiple psychosocial factors on ART adherence. RESULTS: A total of 734 (68.53%) follow-up participants were finally included in this study among the 1071 baseline participants, of whom 91.28% (670/734) had self-reported optimal ART adherence. Unemployment (aOR = 1.75, 95%CI: 1.01-3.02), no medication reminder (aOR = 2.28, 95%CI: 1.09-4.74), low medication self-efficacy (aOR = 2.28, 95%CI: 1.27-4.10), low social cohesion (aOR = 1.82, 95%CI: 1.03-3.19), no social participation (aOR = 5.65, 95%CI: 1.71-18.63), and ART side effects (aOR = 0.46, 95%CI: 0.26-0.81) were barriers to optimal ART adherence. The EFA and second-order latent variable SEM showed a linear relationship (standardized coefficient = 0.43, P < 0.001) between ART adherence and the latent psychosocial (syndemic) factor, which consisted of the three latent factors of medication beliefs and self-efficacy (standardized coefficient = 0.65, P < 0.001), supportive environment (standardized coefficient = 0.50, P < 0.001), and negative emotions (standardized coefficient=-0.38, P < 0.01). The latent factors of medication beliefs and self-efficacy, supportive environment, and negative emotions explained 42.3%, 25.3%, and 14.1% of the variance in the latent psychosocial factor, respectively. CONCLUSIONS: About nine out of ten PLHIV on ART in Guangdong Province self-reported optimal ART adherence. However, more efforts should be made to address barriers to optimal ART adherence.

RESUMEN

BACKGROUND: Compared with other age groups, adolescents living with HIV (ALHIV) are estimated to have lower levels of adherence to antiretroviral treatment. Despite this, we lack evidence on adolescents' adherence patterns over time to inform the customization of intervention strategies. SETTING: Eastern Cape province, South Africa. METHODS: We analyzed data from a cohort of ALHIV (N = 1046, aged 10-19 years at baseline) recruited from 53 public health facilities. The cohort comprised 3 waves of data collected between 2014 and 2018 and routine viral load data from the National Institute for Communicable Disease data warehouse (2014-2019). Durable viral suppression was defined as having suppressed viral load (<1000 copies/mL) at ≥2 consecutive study waves. Group-based multitrajectory model was used to identify adherence trajectories using 5 indicators of self-reported adherence. Logistic regression modeling evaluated the associations between adherence trajectories and durable viral suppression. RESULTS: Overall, 933 ALHIV (89.2%) completed all 3 study waves (55.1% female, mean age: 13.6 years at baseline). Four adherence trajectories were identified, namely, "consistent adherence" (49.8%), "low start and increasing" (20.8%), "gradually decreasing" (23.5%), and "low and decreasing" (5.9%). Adolescents experiencing inconsistent adherence trajectories were more likely to be older, live in rural areas, and have sexually acquired HIV. Compared with the consistent adherence trajectory, the odds of durable viral suppression were lower among adolescents in the low start and increasing (adjusted odds ratio [aOR]: 0.62, 95% CI: 0.41 to 0.95), gradually decreasing (aOR: 0.40, 95% CI: 0.27 to 0.59), and the low and decreasing adherence (aOR: 0.25, 95% CI: 0.10 to 0.62) trajectories. CONCLUSIONS: Adherence to antiretroviral treatment remains a challenge among ALHIV in South Africa. Identifying adolescents at risk of nonadherence, based on their adherence trajectories may inform the tailoring of adolescent-friendly support strategies.

RESUMEN

BACKGROUND: Cryptococcal meningitis (CM) remains a major cause of death among people living with HIV in rural sub-Saharan Africa. We previously reported that a CM diagnosis and treatment program (CM-DTP) improved hospital survival for CM patients in rural, northern Uganda. This study aimed to evaluate the impact on long-term survival. METHODS: We conducted a retrospective study at Lira Regional Referral Hospital in Uganda evaluating long-term survival (≥1 year) of CM patients diagnosed after CM-DTP initiation (February 2017-September 2021). We compared with a baseline historical group of CM patients before CM-DTP implementation (January 2015-February 2017). Using Cox proportional hazards models, we assessed time-to-death in these groups, adjusting for confounders. RESULTS: We identified 318 CM patients, 105 in the Historical Group, and 213 in the CM-DTP Group. The Historical Group had a higher 30-day mortality of 78.5% compared to 42.2% in the CM-DTP Group. The overall survival rate for the CM-DTP group at three years was 25.6%. Attendance at follow-up visits (HR:0.13, 95% CI: [0.03-0.53], p <0.001), ART adherence (HR:0.27, 95% CI: [0.10-0.71], p = 0.008), and fluconazole adherence: (HR:0.03, 95% CI: [0.01-0.13], p <0.001), weight >50kg (HR:0.54, 95% CI: [0.35-0.84], p = 0.006), and performance of therapeutic lumbar punctures (HR:0.42, 95% CI: [0.24-0.71], p = 0.001), were associated with lower risk of death. Altered mentation was associated with increased death risk (HR: 1.63, 95% CI: 1.10-2.42, p = 0.016). CONCLUSION: Long-term survival of CM patients improved after the initiation of the CM-DTP. Despite this improved survival, long-term outcomes remained sub-optimal, suggesting that further work is needed to enhance long-term survival.

RESUMEN

A high prevalence of mpox in men who have sex with men and in people with HIV, plus visually striking and contagious lesions, have raised concerns for mpox stigma. 24 PCR-confirmed mpox patients were surveyed over the course of three months, utilizing an mpox stigma scale adapted from the HIV Stigma Scale plus assessment of pain, analgesic efficacy, and healthcare experiences. Participants were cis-male (100%), with male sexual partners (96%), mostly African-American (88%), and living with HIV (79%). Patients answered 4-16 of 24 (mean 10) stigma questions affirmatively, particularly related to negative effects of mpox on the LGBTQ community. 79% reported pain, most commonly of limbs and perianal area, with perianal pain being rated most severe. The most effective pain relief occurred with opioids (100% major relief, n = 2) and tecovirimat (63% major relief, 25% moderate, n = 16). Patients were satisfied with care provided at the studied clinics, but had negative experiences at all other mentioned sites.

RESUMEN

Acute pancreatitis is seen in patients with human immunodeficiency virus (HIV) as a result of antiretroviral drug therapy and hypertriglyceridemia. Thrombotic complications are known in patients of HIV as a result of endothelial dysfunction, and right-sided infective endocarditis (IE) is seen in HIV patients mostly due to intravenous (IV) drug abuse. However, the occurrence of acute pancreatitis with sepsis, IE, and bilateral thromboembolism in the same patient is rare. Here, we report this case of a treatment-naive nondrug abuser HIV patient with acute pancreatitis in sepsis, IE, and bilateral pulmonary thromboembolism who recovered completely with treatment.

RESUMEN

INTRODUCTION: Adherence counselling with point-of-care (POC) drug-level feedback using a novel tenofovir assay may support pre-exposure prophylaxis (PrEP) adherence; however, perceptions of urine testing and its impact on adherence are not well studied. We qualitatively examined how POC tenofovir testing was experienced by transgender women (TGW) in Uganda. METHODS: Within a cluster randomized trial of peer-delivered HIV self-testing, self-sampling for sexually transmitted infections and PrEP among HIV-negative TGW showing overall low PrEP prevention-effective adherence (NCT04328025), we conducted a nested qualitative sub-study of the urine POC assay among a random sample of 30 TGW (August 2021-February 2022). TGW interviews explored: (1) experiences with POC urine tenofovir testing and (2) perceptions of PrEP adherence counselling with drug-level feedback. We used an inductive content analytic approach for analysis. RESULTS: Median age was 21 years (interquartile range 20-24), and 70% engaged in sex work. Four content categories describe how TGW experienced POC urine tenofovir testing: (1) Urine tenofovir testing was initially met with scepticism: Testing urine to detect PrEP initially induced anxiety, with some perceptions of being intrusive and unwarranted. With counselling, however, participants found POC testing acceptable and beneficial. (2) Alignment of urine test results and adherence behaviours: Drug-level feedback aligned with what TGW knew about their adherence. Concurrence between pill taking and tenofovir detection in urine reinforced confidence in test accuracy. (3) Interpretation of urine tenofovir results: TGW familiar with the interpretation of oral-fluid HIV self-tests knew that two lines on the test device signified positivity (presence of HIV). However, two lines on the urine test strip indicated a positive result for non-adherence (absence of tenofovir), causing confusion. Research nurses explained the difference in test interpretation to participants' satisfaction. (4) White coat dosing: Some TGW deliberately chose not to attend scheduled clinic appointments to avoid detecting their PrEP non-adherence during urine testing. They restarted PrEP before returning to clinic, a behaviour called "white coat dosing." CONCLUSIONS: Incorporating POC urine testing into routine PrEP adherence counselling was acceptable and potentially beneficial for TGW but required attention to context. Additional research is needed to identify effective strategies for optimizing adherence monitoring and counselling for this population.

RESUMEN

INTRODUCTION: In South Africa, the HIV care cascade remains suboptimal. We investigated the impact of small conditional financial incentives (CFIs) and male-targeted HIV-specific decision-support application (EPIC-HIV) on the HIV care cascade. METHODS: In 2018, in uMkhanyakude district, 45 communities were randomly assigned to one of four arms: (i) CFI for home-based HIV testing and linkage to care within 6 weeks (R50 [US$3] food voucher each); (ii) EPIC-HIV which are based on self-determination theory; (iii) both CFI and EPIC-HIV; and (iv) standard of care. EPIC-HIV consisted of two components: EPIC-HIV 1, provided to men through a tablet before home-based HIV testing, and EPIC-HIV 2, offered 1 month later to men who tested positive but had not yet linked to care. Linking HITS trial data to national antiretroviral treatment (ART) programme data and HIV surveillance programme data, we estimated HIV status awareness after the HITS trial implementation, ART status 3 month after the trial and viral load suppression 1 year later. Analysis included all known individuals living with HIV in the study area including those who did not participated in the HITS trial. RESULTS: Among the 33,778 residents in the study area, 2763 men and 7266 women were identified as living with HIV by the end of the intervention period and included in the analysis. After the intervention, awareness of HIV-positive status was higher in the CFI arms compared to non-CFI arms (men: 793/908 [87.3%] vs. 1574/1855 [84.9%], RR = 1.03 [95% CI: 0.99-1.07]; women: 2259/2421 [93.3%] vs. 4439/4845 [91.6%], RR = 1.02 [95% CI: 1.00-1.04]). Three months after the intervention, no differences were found for linkage to ART between arms. One year after the intervention, only 1829 viral test results were retrieved. Viral suppression was higher but not significant in the EPIC-HIV intervention arms among men (65/99 [65.7%] vs. 182/308 [59.1%], RR = 1.11 [95% CI: 0.88-1.40]). CONCLUSIONS: Small CFIs can contribute to achieve the first step of the HIV care cascade. However, neither CFIs nor EPIC-HIV was sufficient to increase the number of people on ART. Additional evidence is needed to confirm the impact of EPIC-HIV on viral suppression.
