A Cascade of Interventions to Promote Adherence to Antiretroviral Therapy in African Countries

"If It Weren't for This, We'd Be Sick"-Perspectives From Participants of a Couple-Based HIV Treatment and Support Program During Prenatal and Postpartum Periods in Zambézia Province, Mozambique

BACKGROUND

Engagement in HIV care and treatment services during pregnancy is key to eliminating vertical transmission. One barrier to retention of pregnant and lactating women is insufficient support from male partners. Reframing HIV services as couple-based may increase adherence among men and women. As part of a cluster randomized trial evaluating an intervention offering seroconcordant couples living with HIV joint follow-up in HIV services and sessions with a health counselor and couple peer educators, we assessed participants' perspectives and experiences regarding the intervention.

SETTING

Zambézia Province is a rural, low-income, and medically underserved region of central Mozambique.

METHODS

We conducted semistructured interviews with a subset of participants enrolled in the intervention arm. The objectives were to explore participants' (1) experiences with couples-based HIV care and the educational/support sessions; (2) perceived impacts of the intervention; and (3) suggestions for intervention improvement. Interviews conducted by experienced interviewers were audio-recorded, transcribed, and deductively coded.

RESULTS

Sixty-four participants were interviewed. Participants described the counselor and the peer educators as trustworthy and the sessions as improving their HIV-related knowledge. Receiving joint HIV services was convenient and motivated some participants to remain adherent to care. Participants provided few suggestions to improve the intervention, although a few female participants did state that they wished their male partners had participated more readily in the joint sessions and medication pick-ups at the health facilities.

CONCLUSIONS

Participants described positive experiences with and perceived benefits from the intervention, making this intervention acceptable within the local context.

HealthCall: Smartphone Enhancement of Brief Interventions to Improve HIV Medication Adherence Among Patients in HIV Care

Heavy drinking among people living with HIV (PLWH) reduces ART adherence and worsens health outcomes. Lengthy interventions are not feasible in most HIV care settings, and patients infrequently follow referrals to outside treatment. Utilizing visual and video features of smartphone technology, we developed HealthCall as an electronic means of increasing patient involvement in a brief intervention to reduce drinking and improve ART adherence. The objective of the current study is to evaluate the efficacy of HealthCall to improve ART adherence among PLWH who drink heavily when paired with two brief interventions: the National Institute on Alcoholism and Alcohol Abuse (NIAAA) Clinician's Guide (CG) or Motivational Interviewing (MI). Therefore, we conducted a 1:1:1 randomized trial among 114 participants with alcohol dependence at a large urban HIV clinic. Participants were randomized to one of three groups: (1) CG only (n = 37), (2) CG and HealthCall (n = 38), or (3) MI and HealthCall (n = 39). Baseline interventions targeting drinking reduction and ART adherence were ~ 25 min, with brief (10-15 min) booster sessions at 30 and 60 days. The outcome was ART adherence assessed using unannounced phone pill-count method (possible adherence scores: 0-100%) at 30-day, 60-day, 3, 6, and 12 months. Analyses were conducted using generalized linear mixed models with pre-planned contrasts. Of the 114 enrolled patients, 58% were male, 75% identified as Black/African American, 28% were Hispanic, and 62% had less than a high school education. The mean age was 47.5 years (standard deviation [SD]  10 years) and the mean number of years since they were diagnosed with HIV was 18.6 (SD 7.6). Participants assigned to HealthCall to extend the CG had increased levels of ART adherence at 60-day and 6-month follow-up (compared to CG only), although there was no statistically significant difference by 12-month follow-up. Participants who were assigned to HealthCall to extend the MI never had statistically significant higher levels of ART adherence. These results suggest that the use of a smartphone app can be used to initially extend the reach of a brief drinking intervention to improve ART adherence over a short period of time; however, sustained long-term improvements in ART adherence after intervention activity ends remains a challenge.

My Way: development and preliminary evaluation of a novel delivery system for PrEP and other sexual health needs of young women in Western Kenya

INTRODUCTION

Young women in sub-Saharan Africa are a priority population for HIV prevention, yet challenges with adherence and persistence to HIV pre-exposure prophylaxis (PrEP) are common. This study involved the development and pilot testing of My Way-a novel delivery system for PrEP and co-packaged sexual health services.

METHODS

My Way was developed in Kisumu, Kenya through a user-centred design process (2020). The intervention involves peer-delivery and support for HIV testing and PrEP use, self-collected vaginal swabs for sexually transmitted infection (STI) testing, pregnancy testing, oral contraceptive pills, self-injectable medroxyprogesterone and/or condoms. My Way was assessed among 16- to 24-year-old sexually active women in a randomized controlled trial versus standard of care (SoC; 2021-2022). Use of PrEP and other sexual health services were tracked at 1, 3 and 6 months for feasibility. Acceptability was determined by questionnaire. The effect of the intervention on tenofovir diphosphate (TFV-DP) levels was assessed by chi-square test (primary outcome); other predictors were explored with regression analysis.

RESULTS

Among 150 women, the median age was 22 years and the median number of sexual partners was 2. Moderate/severe depression was common (60%). In the intervention arm, peers made 88% (198/225) of possible kit deliveries (177 with PrEP) and 49 STIs were diagnosed. In the SoC arm, 24% (55/225) of expected clinic visits occurred (53 with PrEP); no STI testing was performed. TVF-DP was detected in 16 participants at 6 months: 16% (12/75) in the intervention arm versus 5% (4/75) in the SoC arm (p = 0.03). Persistence among those with ongoing HIV prevention needs (i.e. prevention-effective persistence) was 18% (12/67) versus 7% (4/56; p = 0.08). No women acquired HIV. The intervention was significantly associated with detectable TFV-DP (OR 3.5, 1.1-11.4; p = 0.04); moderate/severe depression trended towards an association with TFV-DP (OR 0.2, 0.03-1.6; p = 0.13).

CONCLUSIONS

My Way is a promising delivery system for PrEP and other sexual health services among young women in Western Kenya. We found high feasibility and acceptability. PrEP use was modest, but higher with My Way compared to SoC. Long-acting PrEP formulations may overcome important barriers to PrEP use and should be explored in combination with the My Way delivery model.

People living with HIV's perspectives of acceptability of fee for home delivery of ART: a qualitative study

INTRODUCTION

Significant progress has been made in the HIV response in South Africa; however, gaps remain in ensuring engagement in care to support life-long medication adherence and viral suppression. The National Department of Health (NDoH) has introduced community-based and clinic-based HIV differentiated service delivery (DSD) models to tackle suboptimal adherence and retention in care. Nevertheless, differentiated care models require adaptation to better serve clients who struggle with adherence. There is limited research on the acceptability of fee for home delivery of ART in resource-constrained settings. The current study investigates the acceptability of fee for home delivery of ART among people living with HIV in South Africa.

METHODS

Two mixed-gender focus group discussions (FGDs) took place between June and November 2019, consisting of 10 participants in each group. A purposive sampling strategy was employed to identify and select 10 people living with HIV who were ART-eligible but not in care, and 10 people living with HIV who were currently taking ART and in care. Participants were grouped according to their treatment status. A coding framework, informed by a priori categories and derived from topics in the interview guide, was developed and utilized to facilitate analysis.

RESULTS

Participants expressed enthusiasm for having ART home-delivered, as it would save the time spent waiting in long queues at the clinic. However, some participants raised concerns about potential payment difficulties due to high unemployment rates in the community. Some participants believed this would be acceptable, as patients already incur costs for travel and food when visiting the clinic. Participants in both FGDs expressed strong concerns about home delivery of their ART based on fear of accidental disclosure, especially for those who have not disclosed to their immediate families and partners.

CONCLUSION

Our study suggests that charging a fee for home delivery is an acceptable and innovative approach to supporting PLHIV in maintaining adherence to their medication and remaining in care.

Intersectional Stigma and Implementation of HIV Prevention and Treatment Services for Adolescents Living with and at Risk for HIV: Opportunities for Improvement in the HIV Continuum in Sub-Saharan Africa

Adolescents in sub-Saharan Africa, specifically adolescent girls and young women, young men who have sex with men, transgender persons, persons who use substances, and adolescents experiencing homelessness experience intersectional stigma, have a high incidence of HIV and are less likely to be engaged in HIV prevention and care. We conducted a thematic analysis informed by the Health and Discrimination Framework using a multiple case study design with five case studies in 3 sub-Saharan African countries. Our analysis found commonalities in adolescents' intersectional stigma experiences across cases, despite different contexts. We characterize how intersectional stigma impacts the uptake and implementation of HIV prevention and treatment services along the continuum for adolescents. Findings reveal how intersectional stigma operates across social-ecological levels and worsens HIV-related outcomes for adolescents. We identify opportunities for implementation science research to address stigma-related barriers to the uptake and delivery of HIV services for adolescents in sub-Saharan Africa.

Effect of multi-month antiretroviral dispensing on HIV clinic attendance at 68 Nigerian Army Reference Hospital, Yaba, Nigeria

Background: Multi-month dispensing (MMD) of antiretroviral therapy has demonstrated benefits for HIV patients and health service delivery systems, including reduced frequency of hospital visits and improved retention. We evaluated the effect of 6-monthly dispensing (MMD6) on patient clinic attendance at a single military facility in the one-year pre- and post-policy change.Methods: This was a descriptive, retrospective, cross-sectional study, exploring the relationship between MMD6 and clinic attendance numbers. We reviewed aggregate clinic attendance records for clients on ART and documented monthly trends in clinic attendance numbers, number of clients current on ART, and amount of ART dispensed.Results: In the pre-MMD6 group, 4 150 patients were included, and 4 190 in the post-MMD6 group. Clinic attendance was 30 407 visits (16 111 pre-MMD6 and 14 296 post-MMD6). An overall mean increase of 326.58 ± 861.81 (95% CI = -874.15 ± 220.98) drugs were dispensed per month; t(11) = -1.31, p = 0.22; mean monthly clinic attendance declined from 1342.8 ± 220.10 visits pre-MMD6 to 1191.33 ± 309.10 post-MMD6 with t(11) = 1.601, p = 0.14, but was not statistically significant.Conclusion: Six-monthly dispensing can be an important tool to reduce HIV clinic volumes and improve antiretroviral access. It is particularly important for care continuity in military facilities where service members may be deployed or transferred to other bases along with their dependents.

Viral load suppression after intensive adherence counselling among adult people living with HIV at Kiswa health centre, Kampala: a retrospective cohort study. Secondary data analysis

BACKGROUND

The Joint United Nations Programme on HIV/AIDS through the 95-95-95 target requires 95% of people living with HIV (PLHIV) on antiretroviral treatment (ART) to be virally suppressed. Viral Load (VL) non-suppression has been found to be associated with suboptimal ART adherence, and Intensive Adherence Counselling (IAC) has been shown to lead to VL re-suppression by over 70% in PLHIV on ART. Currently, there is data paucity on VL suppression after IAC in adult PLHIV in Uganda. This study aimed to evaluate the proportion of VL suppression after IAC and associated factors among adult PLHIV on ART at Kiswa Health Centre in Kampala, Uganda.

METHODS

Study was a retrospective cohort design and employed secondary data analysis to review routine program data. Medical records of adult PLHIV on ART for at least six months with VL non-suppression from January 2018 to June 2020 at Kiswa HIV clinic were examined in May 2021. Descriptive statistics were applied to determine sample characteristics and study outcome proportions. Multivariable modified Poisson regression analysis was employed to assess predictors of VL suppression after IAC.

RESULTS

Analysis included 323 study participants of whom 204 (63.2%) were female, 137 (42.4%) were between the age of 30 and 39 years; and median age was 35 years (interquartile range [IQR] 29-42). Participant linkage to IAC was 100%. Participants who received the first IAC session within 30 days or less after unsuppressed VL result were 48.6% (157/323). Participants who received recommended three or more IAC sessions and achieved VL suppression were 66.4% (202/304). The percentage of participants who completed three IAC sessions in recommended 12 weeks was 34%. Receipt of three IAC sessions (ARR = 1.33, 95%CI: 1.15-1.53, p < 0.001), having baseline VL of 1,000-4,999 copies/ml (ARR = 1.47, 95%CI: 1.25-1.73, p < 0.001) and taking Dolutegravir containing ART regimen were factors significantly associated with VL suppression after IAC.

CONCLUSION

VL suppression proportion of 66.4% after IAC in this population was comparable to 70%, the percentage over which adherence interventions have been shown to cause VL re-suppression. However, timely IAC intervention is needed from receipt of unsuppressed VL results to IAC process completion.

Task-sharing with lay counsellors to deliver a stepped care intervention to improve depression, antiretroviral therapy adherence and viral suppression in people living with HIV: a study protocol for the TENDAI randomised controlled trial

INTRODUCTION

Non-adherence to antiretroviral therapy (ART) is the main cause of viral non-suppression and its risk is increased by depression. In countries with high burden of HIV, there is a lack of trained professionals to deliver depression treatments. This paper describes the protocol for a 2-arm parallel group superiority 1:1 randomised controlled trial, to test the effectiveness and cost effectiveness of the TENDAI stepped care task-shifted intervention for depression, ART non-adherence and HIV viral suppression delivered by lay interventionists.

METHODS AND ANALYSIS

Two hundred and ninety people living with HIV aged ≥18 years with probable depression (Patient Health Questionnaire=>10) and viral non-suppression (≥ 1000 HIV copies/mL) are being recruited from HIV clinics in towns in Zimbabwe. The intervention group will receive a culturally adapted 6-session psychological treatment, Problem-Solving Therapy for Adherence and Depression (PST-AD), including problem-solving therapy, positive activity scheduling, skills to cope with stress and poor sleep and content to target barriers to non-adherence to ART. Participants whose score on the Patient Health Questionnaire-9 remains ≥10, and/or falls by less than 5 points, step up to a nurse evaluation for possible antidepressant medication. The control group receives usual care for viral non-suppression, consisting of three sessions of adherence counselling from existing clinic staff, and enhanced usual care for depression in line with the WHO Mental Health Gap intervention guide. The primary outcome is viral suppression (<1000 HIV copies/mL) at 12 months post-randomisation.

ETHICS AND DISSEMINATION

The study and its tools were approved by MRCZ/A/2390 in Zimbabwe and RESCM-18/19-5580 in the UK. Study findings will be shared through the community advisory group, conferences and open access publications.

Barriers and facilitators to the utilization of the intensive adherence counselling framework by healthcare providers in Uganda: a qualitative study

Background

Uganda Ministry of Health (UMOH) embraced the World Health Organization recommendation for people living with human immunodeficiency virus with a detectable viral load (VL) exceeding 1000 copies/mL to receive intensive adherence counselling (IAC). The IAC framework was developed as a step-by-step guide for healthcare providers to systematically support persons with non-suppressed VL to develop a comprehensive plan for adhering to treatment. The objective of this study was to explore the current practice of the healthcare providers when providing IAC, and identify the barriers and facilitators to the utilization of the UMOH IAC framework at two health centers IV level in rural Uganda.

Methods

This was a descriptive cross-sectional qualitative study that explored the current practices of the healthcare providers when providing IAC, and identified the barriers and facilitators to the utilization of the UMOH IAC framework. We used an interview guide with unstructured questions about what the participants did to support the clients with non-suppressed VL, and semi-structured questions following a checklist of categories of barriers and facilitators that affect ‘providers of care’ as provided by the Supporting the Use of Research Evidence for policy in African health systems (SURE) framework. Current practice as well as the categories of barriers and facilitators formed the a priori themes which guided data collection and analysis. In this study we only included healthcare providers (i.e., medical doctors, clinical officer, nurses, and counsellors) as ‘providers of care’ excluding family members because we were interested in the health system.

Results

A total of 19 healthcare providers took part in the interviews. The healthcare providers reported lack of sufficient knowledge on the UMOH IAC framework; most of them did not receive prior training or sensitization when it was first introduced. They indicated that they lacked counselling and communication skills to effectively utilize the IAC framework, and they were not motivated to utilize it because of the high workload at the clinics compounded by the limited workforce.

Conclusions

Although the UMOH IAC framework is a good step-by-step guide for the healthcare providers, there is need to understand their context and assess readiness to embrace the new behavior before expecting spontaneous uptake and utilization.

How informal healthcare providers improve uptake of HIV testing: qualitative results from a randomized controlled trial

OBJECTIVE

Uganda is HIV-endemic with a prevalence of 5.7%. Lack of epidemic control has been attributed to low engagement with HIV testing. Collaborating with informal healthcare providers, such as traditional healers, has been proposed as a strategy to increase testing uptake. We explored acceptability and implementation of an HIV testing program where traditional healers delivered point-of-care testing and counseling to adults of unknown serostatus (clinicaltrials.gov NCT#03718871).

METHODS

This study was conducted in rural, southwestern Uganda. We interviewed participating traditional healers ( N  = 17) and a purposive sample of trial participants ( N  = 107). Healers were practicing within 10 km of Mbarara township, and 18+ years old. Participants were 18+ years old; sexually active; had received care from participating healers; self-reported not receiving an HIV test in prior 12 months; and not previously diagnosed with HIV infection. Interviews explored perceptions of a healer-delivered HIV testing model and were analyzed following a content-analysis approach.

RESULTS

Most participants were female individuals ( N  = 68, 55%). Healer-delivered HIV testing overcame structural barriers, such as underlying poverty and rural locations that limited use, as transportation was costly and often prohibitive. Additionally, healers were located in villages and communities, which made services more accessible compared with facility-based testing. Participants also considered healers trustworthy and 'confidential'. These qualities explain some preference for healer-delivered HIV testing, in contrast to 'stigmatizing' biomedical settings.

CONCLUSION

Traditional healer-delivered HIV testing was considered more confidential and easily accessible compared with clinic-based testing. Offering services through traditional healers may improve uptake of HIV testing services in rural, medically pluralistic communities.

Interventions addressing the adolescent HIV continuum of care in South Africa: a systematic review and modified Delphi analysis

INTRODUCTION

Compared with adults, adolescents in South Africa have larger gaps at each step of the HIV continuum of care resulting in low levels of viral suppression.

METHODS

We conducted a systematic review and modified Delphi analysis of interventions addressing the HIV continuum of care for adolescents in South Africa. We searched PubMed, Science Direct, and Google Scholar and online conference proceedings from the International AIDS Society, the International AIDS Conference, and the Conference on Retrovirology and Opportunistic Infections from 1 January 2010 to 30 September 2020. We then conducted a modified Delphi analysis with 29 researchers involved in the National Institutes of Health's Fogarty International-supported Adolescent HIV Implementation Science Alliance-South Africa to evaluate interventions for efficacy, feasibility and potential for scale-up.

RESULTS

We identified nine initial published articles containing interventions addressing the adolescent HIV continuum of care in South Africa, including five interventions focused on HIV diagnosis, two on antiretroviral therapy adherence and two on retention in care. No studies addressed linkage to care or transition from paediatric to adult care. Two studies discussed intervention costs. In-home and HIV self-testing, community-based adherence support, and provision of adolescent-friendly services were the most impactful and scalable interventions addressing the adolescent HIV continuum of care.

CONCLUSION

Future interventions should work comprehensively across the adolescent HIV continuum of care and be tailored to the specific needs of adolescents.

Effect of peer-mother interactive programme on prevention of mother-to-child HIV transmission outcomes among pregnant women on anti-retroviral treatment in routine healthcare in Dar es Salaam, Tanzania

Peer support services are increasingly being integrated in programmes for the prevention of mother-to-child HIV transmission (PMTCT). We aimed to evaluate the effect of a peer-mother interactive programme on PMTCT outcomes among pregnant women on anti-retroviral treatment (ART) in routine healthcare in Dar es Salaam, Tanzania. Twenty-three health facilities were cluster-randomized to a peer-mother intervention and 24 to a control arm. We trained 92 ART experienced women with HIV to offer peer education, adherence and psychosocial support to women enrolling in PMTCT care at the intervention facilities. All pregnant women who enrolled in PMTCT care at the 47 facilities from 1st January 2018 to 31st December 2019 were identified and followed up to 31st July 2021. The primary outcome was time to ART attrition (no show >90 days since the scheduled appointment, excluding transfers) and any difference in one-year retention in PMTCT and ART care between intervention and control facilities. Secondary outcomes were maternal viral suppression (<400 viral copies/mL) and mother-to-child HIV transmission (MTCT) by ≥12 months post-partum. Analyses were done using Kaplan Meier and Cox regression (ART retention/attrition), generalized estimating equations (viral suppression) and random effects logistic regression (MTCT); reporting rates, proportions and 95% confidence intervals (CI). There were 1957 women in the peer-mother and 1384 in the control facilities who enrolled in routine PMTCT care during 2018-2019 and were followed for a median [interquartile range (IQR)] of 23 [10, 31] months. Women in both groups had similar median age of 30 [IQR 25, 35] years, but differed slightly with regard to proportions in the third pregnancy trimester (14% versus 19%); advanced HIV (22% versus 27%); and ART naïve (55% versus 47%). Peer-mother facilities had a significantly lower attrition rate per 1000 person months (95%CI) of 14 (13, 16) versus 18 (16, 19) and significantly higher one-year ART retention (95%CI) of 78% (76, 80) versus 74% (71, 76) in un-adjusted analyses, however in adjusted analyses the effect size was not statistically significant [adjusted hazard ratio of attrition (95%CI) = 0.85 (0.67, 1.08)]. Viral suppression (95%CI) was similar in both groups [92% (91, 93) versus 91% (90, 92)], but significantly higher among ART naïve women in peer-mother [91% (89, 92)] versus control [88% (86, 90)] facilities. MTCT (95%CI) was similar in both groups [2.2% (1.4, 3.4) versus 1.5% (0.7, 2.8)]. In conclusion, we learned that integration of peer-mother services in routine PMTCT care improved ART retention among all women and viral suppression among ART naïve women but had no significant influence on MTCT.

"The Money, It's OK but It's not OK": Patients' and Providers' Perceptions of the Acceptability of Cash Incentives for HIV Treatment Initiation in Cape Town, South Africa

Incentive-based interventions are used to encourage HIV testing, linkage to HIV care, and antiretroviral therapy (ART) adherence. Studies assessing efficacy of cash incentives have raised questions about the perceived ethicality of and attitudes towards incentives. Here we explore patients' and health providers' perspectives of the acceptability of a conditional cash transfer for ART initiation after receiving a positive HIV test through community-based services in resource-poor communities in Cape Town, South Africa. Drawing on in-depth interviews with patients and health care workers (HCWs), we find that, despite the perception that cash incentives are effective in promoting ART initiation, significant ambivalence surrounds the acceptability of such incentives. The receipt of a financial incentive was highly moralized, and fraught with challenges. Increasing the acceptability of cash incentives through careful design and delivery of interventions is central to the potential of this type of intervention for improving outcomes along the HIV care continuum.

An evaluation of a combined psychological and parenting intervention for HIV-positive women depressed in the perinatal period, to enhance child development and reduce maternal depression: study protocol for the Insika Yomama cluster randomised controlled trial

BACKGROUND

The combination of poverty, HIV and depression in the perinatal period represents a major public health challenge in many Southern African countries. In some areas, up to a third of HIV-positive women experience perinatal depression. Perinatal depression is associated with negative effects on parenting and key domains of child development including cognitive, behavioural and growth, especially in socio-economically disadvantaged communities. Several studies have documented the benefits of psychological interventions for perinatal depression in low- and middle-income countries, but none have evaluated an integrated psychological and parenting intervention for HIV-positive women using task-sharing. This randomised controlled trial aims to evaluate the effect of a home-based intervention, combining a psychological treatment for depression and a parenting programme for perinatally depressed HIV-positive women.

METHODS

This study is a cluster randomised controlled trial, consisting of 48-60 geospatial clusters. A total of 528 pregnant HIV-positive women aged ≥ 16 years who meet the criteria for depression on the Edinburgh Postnatal Depression Scale (EPDS, score ≥ 9)) are recruited from antenatal clinics in rural KwaZulu-Natal, South Africa. The geospatial clusters are randomised on an allocation ratio of 1:1 to either the intervention or Enhanced Standard of Care (ESoC). The intervention group receives 10 home-based counselling sessions by a lay counsellor (4 antenatal and 6 postnatal sessions) and a booster session at 16 months. The intervention combines behavioural activation for depression with a parenting programme, adapted from the UNICEF/WHO Care for Child Development programme. The ESoC group receives two antenatal and two postnatal counselling support and advice telephone calls. In addition, measures have been taken to enhance the routine standard of care. The co-primary outcomes are child cognitive development at 24 months assessed on the cognitive subscale of the Bayley Scales of Infant Development-Third Edition and maternal depression at 12 months measured by the EPDS.

ANALYSIS

The primary analysis will be a modified intention-to-treat analysis. The primary outcomes will be analysed using mixed-effects linear regression.

DISCUSSION

If this treatment is successful, policymakers could use this model of mental healthcare delivered by lay counsellors within HIV treatment programmes to provide more comprehensive services for families affected by HIV.

Linkage to intensive adherence counselling among HIV-positive persons on ART with detectable viral load in Gomba district, rural Uganda

BACKGROUND

Antiretroviral therapy (ART) adherence is a primary determinant of sustained viral suppression, HIV transmission risk, disease progression and death. The World Health Organization recommends that adherence support interventions be provided to people on ART, but implementation is suboptimal. We evaluated linkage to intensive adherence counselling (IAC) for persons on ART with detectable viral load (VL).

METHODS

Between January and December 2017, we conducted a retrospective chart review of HIV-positive persons on ART with detectable VL (> 1000 copies/ml), in Gomba district, rural Uganda. We abstracted records from eight HIV clinics; seven health center III's (facilities which provide basic preventive and curative care and are headed by clinical officers) and a health center IV (mini-hospital headed by a medical doctor). Linkage to IAC was defined as provision of IAC to ART clients with detectable VL within three months of receipt of results at the health facility. Descriptive statistics and multivariable logistic regression analyses were used to evaluate factors associated with linkage to IAC.

RESULTS

Of 4,100 HIV-positive persons on ART for at least 6 months, 411 (10%) had detectable VL. The median age was 32 years (interquartile range [IQR] 13-43) and 52% were female. The median duration on ART was 3.2 years (IQR 1.8-4.8). A total of 311 ART clients (81%) were linked to IAC. Receipt of ART at a Health Center level IV was associated with a two-fold higher odds of IAC linkage compared with Health Center level III (adjusted odds ratio [aOR] 1.78; 95% CI 1.00-3.16; p = 0.01). Age, gender, marital status and ART duration were not related to IAC linkage.

CONCLUSIONS

Linkage to IAC was high among persons with detectable VL in rural Uganda, with greater odds of linkage at a higher-level health facility. Strategies to optimize IAC linkage at lower-level health facilities for persons with suboptimal ART adherence are needed.

Third Line Antiretroviral Treatment in India: Cohort Analysis and Treatment Outcomes from a Public Health Facility

The National Programme in India provides free third-line antiretroviral treatment (ART) for all people living with HIV (PLHIV). Data of 232 PLHIV initiated on third-line ART from a single center in New Delhi were retrospectively analyzed for virological suppression at 6 and 12 months, factors predicting nonresponse, retention in care, and mortality from June 2016 till December 2019. The mean age at third-line ART initiation was 39.54 ± 11.08 years, 71.5% were males, and 55.02% had HIV duration of >10 years. The mean CD4 count at third-line ART initiation was 260.04 ± 200.4/mm³, and the median viral load (VL) at second-line failure was 61,253 copies/mL (interquartile range, 12,599-315,497 copies/mL). Of the patients, 71.52% achieved virological suppression at 6 months (n = 151), and this was maintained at 12 months-72% (n = 50). The mortality rate among those still in active care was 8.69% (18/207). PLHIV who did not attain virological suppression at 6 months had significantly shorter duration on second-line ART (p = 0.0002), lower peak CD4 achieved on second-line ART (p = 0.039), higher VL at second-line failure (p = 0.012), and lower body weight (p < 0.0001). On univariate analysis, lower CD4 peak on second-line ART (p = 0.019), lower CD4 count at third-line ART initiation (p = 0.004), and lower body weight (p = 0.0002) were significantly predictive of virological nonsuppression at 6 months. Successful implementation of a third-line ART program can indeed be done through a public health approach. Intensive adherence support, nutritional rehabilitation, and regular viral load monitoring are crucial for improved clinical and virological outcomes.
