Adherence to antiretroviral therapy in Jinja, Uganda: a six-year follow-up study

Intramuscular versus Enteral Penicillin Prophylaxis to Prevent Progression of Rheumatic Heart Disease: Study protocol for a non-inferiority randomized trial (the GOALIE trial)

BACKGROUND

Rheumatic Heart Disease (RHD) persists as a major cardiovascular driver of mortality and morbidity among young people in low- and middle-income countries. Secondary antibiotic prophylaxis (SAP) with penicillin remains the cornerstone of RHD control, however, sub-optimal treatment adherence undermines most secondary prevention programs. Many of the barriers to optimal SAP adherence are specific to the intramuscular form of penicillin and may potentially be overcome by use of oral penicillin. This non-inferiority trial is comparing the efficacy of intramuscular to oral penicillin SAP to prevent progression of mild RHD at 2 years.

METHODS/DESIGN

The Intramuscular versus Enteral Penicillin Prophylaxis to Prevent Progression of Rheumatic Heart Disease (GOALIE) trial is randomizing Ugandan children aged 5-17 years identified by echocardiographic screening with mild RHD (Stage A or B as defined by 2023 World Heart Federation criteria) to Benzathine Benzyl Penicillin G (BPG arm, every-28-day intramuscular penicillin) or Phenoxymethyl Penicillin (Pen V arm, twice daily oral penicillin) for a period of 2 years. A blinded echocardiography adjudication panel of 3 RHD experts and 2 cardiologists is determining the echocardiographic stage of RHD at enrollment and will do the same at study completion by consensus review. Treatment adherence and study retention are supported through peer support groups and case management strategies. The primary outcome is the proportion of children in the Pen V arm who progress to more advanced RHD compared to those in the BPG arm. Secondary outcomes are patient-reported outcomes (treatment acceptance, satisfaction, and health related quality of life), costs, and cost-effectiveness of oral compared to intramuscular penicillin prophylaxis for RHD. A total sample size of 1004 participants will provide 90% power to demonstrate non-inferiority using a margin of 4% with allowance for 7% loss to follow-up. Participant enrollment commenced in October 2023 and final participant follow-up is expected in December 2026. The graphical abstract (Figure 1) summarizes the flow of echocardiographic screening, participant enrollment and follow-up.

DISCUSSION

The GOALIE trial is critical in global efforts to refine a pragmatic approach to secondary prevention for RHD control. GOALIE insists that the inferiority of oral penicillin be proven contemporarily and against the most important near-term clinical outcome of progression of RHD severity. This work also considers other factors that could influence the adoption of oral prophylaxis and change the calculus for acceptable efficacy including patient-reported outcomes and costs.

Experiences of people living with HIV in low- and middle-income countries and their perspectives in self-management: a meta-synthesis

INTRODUCTION

Availability of anti-retroviral treatment has changed HIV in to a manageable chronic disease, making effective self-management essential. However, only a few studies in low- and middle-income countries (LMICs) reported experiences of people living with HIV (PLWH) on self-management.

METHODS

This meta-synthesis of qualitative studies investigated perspectives of PLWH in LMICs on self-management. Various databases, including PubMed, EMBASE, EBSCO, and CINHAL, were searched through June 2022. Relevant additional articles were also included using cross-referencing of the identified papers. We used a thematic synthesis guided by the "Model of the Individual and Family Self-Management Theory" (IFSMT).

RESULT

PLWH in LIMICs experience a variety of challenges that restrict their options for effective self-management and compromises their quality of life. The main ones include: misconceptions about the disease, poor self-efficacy and self-management skills, negative social perceptions, and a non-patient-centered model of care that reduces the role of patients. The experiences that influenced the ability to practice self-management are summarized in context (the condition itself, physical and environmental factors, individual and family factors) and process factors (knowledge and beliefs, relationship with the health care worker, self-regulation skills and abilities, and social facilitation). Context and process greatly impacted quality of life through the self-management practices of the patients.

CONCLUSION AND RECOMMENDATION

PLWH encounter multiple challenges, are not empowered enough to manage their own chronic condition, and their needs beyond medical care are not addressed by service providers. Self-management practice of these patients is poor, and service providers do not follow service delivery approaches that empower patients to be at the center of their own care and to achieve an effective and sustainable outcome from treatment. These findings call for a comprehensive well thought self-management interventions.

Determinants of viral load non-suppression among adolescents in Mbale District, Eastern Rural Uganda

BACKGROUND

Adolescents are lagging behind in the "third 95" objective of the Joint United Nations Program on HIV/AIDS requiring 95% of individuals on antiretroviral therapy (ART) to have viral load (VL) suppression. This study aimed to describe factors associated with viral non-suppression among adolescents in Mbale district, Uganda.

METHODS

We conducted a retrospective review of routinely collected HIV programme records. Data such as age, education, ART Regimen, ART duration, WHO Clinical stage, comorbidities, etc., were extracted from medical records for the period January 2018 to December 2018. Descriptive analysis was done for continuous variables using means and frequencies to describe study sample characteristics, and to determine the prevalence of outcome variables. We used logistic regression to assess factors associated with VL non-suppression among adolescents.

RESULTS

The analysis included 567 HIV-infected adolescents, with 300 (52.9%) aged between 13 to 15 years, 335 (59.1%) female, and mean age of 15.6 years (interquartile range [IQR] 13.5-17.8. VL non-suppression was 31.4% (178/567). Male sex (AOR = 1.78, 95% CI 1.06, 2.99; p < 0.01), age 16-19 years (AOR = 1.78, 95% CI 1.06, 2.99; p < 0.05), No formal education (AOR = 3.67, 95% CI 1.48-9.09; p < 0.01), primary education (AOR = 2.23, 95% CI 1.05-2.32; p < 0.01), ART duration of > 12 months to 5 years (AOR = 3.20, 95% CI 1.31-7.82; p < 0.05), ART duration > 5 years (AOR = 3.47, 95% CI 1.39- 8.66; p < 0.01), WHO Clinical Stage II (AOR = 0.48, 95% CI: 0.28, 0.82; p < 0.01), second-line ART regimen (AOR = 2.38, 95% CI 1.53-3.72; p < 0.001) and comorbidities (AOR = 3.28, 95% CI 1.20-9.00; p < 0.05) were significantly associated with viral non-suppression.

CONCLUSIONS

VL non-suppression among adolescents was almost comparable to the national average. VL non-suppression was associated with being male, age 16-19 years, education level, duration on ART therapy, WHO Clinical Staging II, second-line ART regimen, and presence of comorbidities. Adolescent-friendly strategies to improve VL suppression e.g. peer involvement, VL focal persons to identify and actively follow-up non-suppressed adolescents, patient education on VL suppression and demand creation for ART are needed, especially for newly-initiated adolescents and adolescents on ART for protracted periods, to foster attainment of the UNAIDS 95-95-95 targets.

Alcohol consumption increases non-adherence to ART among people living with HIV enrolled to the community-based care model in rural northern Uganda

Background

Non-adherence to anti-retroviral therapy (ART) is associated with considerable morbidity and mortality among people living with Human Immunodeficiency Virus (PLHIV). Community-based ART delivery model offers a decentralized and patient-centered approach to care for PLHIV, with the advantage of improved adherence to ART hence good treatment outcomes. However, data are limited on the magnitude of non-adherence to ART among PLHIV enrolled to the community-based ART model of care. In this study, we determined the frequency of non-adherence to ART and the associated factors among PLHIV enrolled to the community-based ART delivery model in a large health facility in rural northern Uganda.

Methods

This analytic cross-sectional study randomly sampled participants from 21 community drug distribution points at the AIDS Support Organization (TASO) in Gulu district, northern Uganda. Data were collected using a standardized and pre-tested questionnaire, entered in Epi-Data and analyzed in Stata at univariate, bivariate, and multivariate analyses levels. Binary logistic regression analysis was used to determine factors independently associated with non-adherence to ART, reported using odds ratio (OR) and 95% confidence level (CI). The level of statistical significance was 5%.

Results

Of 381 participants, 25 (6.6%) were non-adherent to ART and this was significantly associated with alcohol consumption (Adjusted (aOR), 3.24; 95% CI, 1.24–8.34). Other factors namely being single/or never married (aOR, 1.97; 95% CI, 0.62–6.25), monthly income exceeding 27 dollars (aOR, 1.36; 95% CI, 0.52–3.55), being on ART for more than 5 years (aOR, 0.60; 95% CI, 0.23–1.59), receipt of health education on ART side effects (aOR, 0.36; 95% CI, 0.12–1.05), and disclosure of HIV status (aOR, 0.37; 95% CI, 0.04–3.20) were not associated with non-adherence in this setting.

Conclusion

Non-adherence to ART was low among PLHIV enrolled to community-based ART delivery model but increases with alcohol consumption. Accordingly, psychosocial support programs should focus on alcohol consumption.

Scaling-up PrEP Delivery in Sub-Saharan Africa: What Can We Learn from the Scale-up of ART?

Purpose of Review

Clinical trials have found that PrEP is highly effective in reducing risk of HIV acquisition across types of exposure, gender, PrEP regimens, and dosing schemes. Evidence is urgently needed to inform scale-up of PrEP to meet the ambitious WHO/UNAIDS prevention target of 3,000,000 individuals on PrEP by 2020.

Recent Findings

Successful models of delivering HIV services at scale evolved from years of formal research and programmatic evidence. These efforts produced lessons-learned relevant for scaling-up PrEP delivery, including the importance of streamlining laboratory tests, expanding prescription and management authority, differentiating medication access points, and reducing stigma and barriers of parental consent for PrEP uptake. Further research is especially needed in areas differentiating PrEP from ART delivery, including repeat HIV testing to ensure HIV negative status and defining and measuring prevention-effective adherence.

Summary

Evidence from 15 years of ART scale-up could immediately inform a public health approach to PrEP delivery.

Are treatment supporters relevant in long-term Antiretroviral Therapy (ART) adherence? Experiences from a long-term ART cohort in Uganda

BACKGROUND

This study aimed to understand the relevance of treatment supporters in adherence among people living with HIV taking Anti-retroviral therapy (ART) for more than five years in Uganda.

METHODS

In-depth interviews were conducted with 50 participants (28 women and 22 men) of the Complications of Long-Term ART (CoLTART) cohort with experience of at least five years on ART in Uganda. Participants were stratified by line of ART regimen and viral loads of less or above 1000 copies/ml. Data were analyzed thematically.

RESULTS

Many participants felt that a treatment supporter was most useful at the beginning of therapy before individuals get used to the drugs or when they are still weak. However, this did not reflect treatment outcomes, as many individuals without treatment supporters had failed on first line ART regimens and were switched to second line ART. Those who were still on first line had viral loads of ≥1000 copies/ml. There was a preference for female treatment supporters, many of who were persistent in their supportive role.

CONCLUSION

Treatment supporters remain important in adherence to long-term ART. HIV-care providers need to encourage the involvement of a treatment supporter for individuals taking ART long-term.

What causes non-adherence among some individuals on long term antiretroviral therapy? Experiences of individuals with poor viral suppression in Uganda

Background

Antiretroviral therapy (ART) use by people living with HIV reduces HIV transmission, morbidity, mortality, and improves quality of life. Good ART adherence is required to achieve these benefits. We investigated how the environmental, social, economic and behavioural experiences of people living with HIV with poor viral suppression could explain their non-adherence to long term ART.

Methods

This qualitative cross-sectional study was conducted in Uganda between September 2015 and April 2016. Thirty individuals on ART for 5 years or more (10 on first line and 20 on second line), with poor viral suppression, were randomly selected from a cohort of people living with HIV on ART. In-depth interviews about ART; awareness, adherence counselling, obstacles to daily adherence and regimen switches were conducted. Emerging themes from the interviews transcripts and field notes were identified and thematic content analysis done. Participants’ consent, compensation, confidentiality and study ethical approvals were ensured.

Results

We found that poor adherence to long term ART was due to: travel for work or social activities, stigma, receiving little or no continuous ART adherence education, alcohol consumption and use of alternative ‘HIV cure’ medicines. Other reasons included; ART side effects, treatment fatigue, belief that long-term ART or God can ‘cure HIV’, and food security.

Conclusions

Achieving optimal ART benefits requires continuous provision of ART adherence education to individuals on long term ART. This helps them overcome the challenges related to living with HIV: worries of food insecurity, alcohol misuse, economic hardship, and beliefs in HIV cures and use of unproven alternative HIV treatments. People living with HIV who travel require adherence support and larger quantities of ART refills to cover their time away.

Patient-Initiated Repackaging of Antiretroviral Therapy, Viral Suppression and Drug Resistance

Patient-initiated repackaging of antiretroviral therapy (ART) refers to removal of ART medications from their original manufacturer's containers, and putting them into alternative containers. This behavior may be triggered by stigma associated with HIV infection, and may impact patient outcomes. We assessed association between patient initiated repackaging of ART and failure to achieve viral suppression (FVS) in a sample of 450 HIV-infected adults (≥8 years) on first line ART for ≥6 months. FVS was defined as a plasma HIV RNA level ≥400 copies/mL. A total of 197 (43.7%) patients reported repackaging their ART medications. One hundred ninety-one patients (42.4%) failed to suppress and FVS was associated with medication repackaging [adjusted odds ratio (aOR), 2.2; 95% CI 1.4-3.3.] Adherence to ART was also associated with FVS (aOR; 0.4; 95% CI 0.2-0.6.). Benefits of retaining drugs in their original packaging along with adherence to ART should be emphasized to reduce the risk of FVS.

Understanding Sustained Retention in HIV/AIDS Care and Treatment: a Synthetic Review

Sustained retention represents an enduring and evolving challenge to HIV treatment programs in Africa. We present a theoretical framework for sustained retention borrowing from ecologic principles of sustainability and dynamic adaptation. We posit that sustained retention from the patient perspective is dependent on three foundational principles: (1) patient activation: the acceptance, prioritization, literacy, and skills to manage a chronic disease condition, (2) social normalization: the engagement of a social network and harnessing social capital to support care and treatment, and (3) livelihood routinization: the integration of care and treatment activities into livelihood priorities that may change over time. Using this framework, we highlight barriers specific to sustained retention and review interventions addressing long-term, sustained retention in HIV care with a focus on Sub-Saharan Africa.

Changing forms of HIV-related stigma along the HIV care and treatment continuum in sub-Saharan Africa: a temporal analysis

OBJECTIVES

Stigma remains pervasive for people living with HIV (PLHIV) in sub-Saharan Africa, undermining care engagement. Using everyday, biographical and epochal temporalities, we explored the manifestation of stigma at different stages of the HIV care continuum in seven health and demographic surveillance sites in Eastern and Southern Africa.

METHODS

Between 2015 and 2016, we conducted qualitative in-depth interviews with 264 PLHIV, 54 health providers and 48 family members of people who had died from HIV. Topic guides explored experiences of HIV testing, care and treatment services. Data were analysed thematically, aided by NVivo 10.

RESULTS

In everyday time across these communities, stigma was evident in the presence of gossiping and the relative absence of supportive interpersonal discourse, which fuelled judicious disclosure. This was especially disruptive at testing, counselling and early antiretroviral therapy adherence stages of care. Biographical time framed everyday stigma events, highlighting the dilemma of disclosure in relation to sexual relationship norms, as well as the interfacing of age and healthcare continuum points. Epochal patriarchal relations gave a structural context to everyday and biographical stigma dynamics. Historical shifts to social acceptance of PLHIV within these communities, while positive, were complicated by stigma in everyday life and in respect of biographical goals like having a family. Moreover, low community-level resistance to HIV-related stigma jeopardised stigma reduction strategies.

CONCLUSIONS

Despite improvements to HIV care services, stigma remains pervasive across the HIV care continuum in these sites. Context-specific interventions are needed to address stigma and discrimination of PLHIV within the community and in health services, and greater reflection is required to ensure policies aiming to expand HIV treatment do not exacerbate stigma and result in negative HIV outcomes.

Test and treat: the early experiences in a clinic serving women at high risk of HIV infection in Kampala

At the end of 2013, the Government of Uganda issued guidance recommending provision of Anti-Retroviral Treatment (ART) to HIV-positive people in key populations, including female sex workers, regardless of CD4 cell count. We describe the implementation of this new guidance in a clinic serving women at high risk of HIV infection in Kampala. Between July and December 2015, we conducted repeat in-depth interviews with 15 women attending the clinic after the change in guidelines, to explore their perceptions regarding prompt ART initiation. The sample included some women who were HIV-negative and women who had both started and deferred ART. We conducted a data-led thematic analysis of the material from the interviews. A total of 257 of 445 eligible women had started ART; others were undecided or had not returned to the clinic after receiving the new information. Participants recounted varying experiences with the provision of prompt treatment. At an individual level, a history of treatment for opportunistic infections and other illnesses, coupled with relatively poor health, encouraged some to initiate ART promptly. However, knowledge of friends/relatives already on ART who had experienced side effects caused others to delay starting, fearing the same experience for themselves. A number of women questioned why they should start treatment when they were not sick. Situational factors such as work and residence (with many sharing single rooms) caused discomfort among newly diagnosed women who feared disclosure and stigma that would result from taking ART when they were not ill. Alcohol consumption and irregular working hours affected perceptions of future adherence, making prompt ART harder to embrace for some. Our findings show the challenges that influence the delay of treatment initiation, and/or the decision to defer receiving information on ART, with implications for the success of the test and treat programmes and guidelines.

Patient-reported barriers and facilitators to antiretroviral adherence in sub-Saharan Africa

OBJECTIVE

The aim of this study was to identify the range and frequency of patient-reported barriers and facilitators to antiretroviral treatment (ART) adherence in sub-Saharan Africa (SSA).

DESIGN

Studies from 2005 to 2016 were identified by searching 10 electronic databases and through additional hand and web-searching.

METHODS

Inclusion criteria were HIV-positive adults taking ART based in any SSA country, qualitative study or quantitative survey and included at least one patient-reported barrier or facilitator to ART adherence. Exclusion criteria were only including data from treatment-naive patients initiating ART, only single-dose treatment, participants residing outside of SSA and reviews.

RESULTS

After screening 11 283 records, 154 studies (161 papers) were included in this review. Forty-three barriers and 30 facilitators were reported across 24 SSA countries. The most frequently identified barriers across studies were forgetting (n = 76), lack of access to adequate food (n = 72), stigma and discrimination (n = 68), side effects (n = 67) and being outside the house or travelling (n = 60). The most frequently identified facilitators across studies were social support (n = 60), reminders (n = 55), feeling better or healthier after taking ART (n = 35), disclosing their HIV status (n = 26) and having a good relationship with a health provider (n = 22).

CONCLUSION

This review addresses the gap in knowledge by collating all the patient-reported barriers and facilitators to ART adherence in SSA. Current barriers measures need to be adapted or new tools developed to include the wide variety of factors identified. The factors that have the greatest impact need to be isolated so interventions are developed that reduce the barriers and enhance the facilitators.

The Role of ARV Associated Adverse Drug Reactions in Influencing Adherence Among HIV-Infected Individuals: A Systematic Review and Qualitative Meta-Synthesis

Poor adherence remains a major barrier to achieving the clinical and public health benefits of antiretroviral drugs (ARVs). A systematic review and qualitative meta-synthesis was conduct to evaluate how ARV adverse drug reactions may influence ARV adherence. Thirty-nine articles were identified, and 33 reported that ARV adverse drug reactions decreased adherence and six studies found no influence. Visually noticeable adverse drug reactions and psychological adverse reactions were reported as more likely to cause non-adherence compared to other adverse drug reactions. Six studies reported a range of adverse reactions associated with EFV-containing regimens contributing to decreased adherence. Informing HIV-infected individuals about ARV adverse drug reactions prior to initiation, counselling about coping mechanisms, and experiencing the effectiveness of ARVs on wellbeing may improve ARV adherence.

Determinants of adherence to antiretroviral therapy among HIV-positive adults in sub-Saharan Africa: a systematic review

OBJECTIVE

The rapid scale up of antiretroviral treatment (ART) in sub-Saharan Africa (SSA) has resulted in an increased focus on patient adherence. Non-adherence can lead to drug-resistant HIV caused by failure to achieve maximal viral suppression. Optimal treatment requires the identification of patients at high risk of suboptimal adherence and targeted interventions. The aim of this review was to identify and summarise determinants of adherence to ART among HIV-positive adults.

DESIGN

Systematic review of adherence to ART in SSA from January 2002 to October 2014.

METHODS

A systematic search was performed in 6 databases (PubMed, Cochrane Library, EMBASE, Web of Science, Popline, Global Health Library) for qualitative and quantitative articles. Risk of bias was assessed. A meta-analysis was conducted for pooled estimates of effect size on adherence determinants.

RESULTS

Of the 4052 articles screened, 146 were included for final analysis, reporting on determinants of 161 922 HIV patients with an average adherence score of 72.9%. Main determinants of non-adherence were use of alcohol, male gender, use of traditional/herbal medicine, dissatisfaction with healthcare facility and healthcare workers, depression, discrimination and stigmatisation, and poor social support. Promoters of adherence included counselling and education interventions, memory aids, and active disclosure among people living with HIV. Determinants of health status had conflicting influence on adherence.

CONCLUSIONS

The sociodemographic, psychosocial, health status, treatment-related and intervention-related determinants are interlinked and contribute to optimal adherence. Clinics providing ART in SSA should therefore design targeted interventions addressing these determinants to optimise health outcomes.

Long-Term Antiretroviral Treatment Adherence in HIV-Infected Adolescents and Adults in Uganda: A Qualitative Study

BACKGROUND

Long-term success of HIV antiretroviral therapy requires near-perfect adherence, maintained throughout one's lifetime. However, perceptions towards ART and patterns of adherence may change during the life course. We assessed challenges to long-term adherence in adolescents and adults in three regional HIV treatment centers in Uganda.

METHODS

We conducted 24 in-depth interviews and 2 focus group discussions with a total of 33 health-care providers and expert clients (HIV patients on long-term ART who assist with adherence support of fellow patients). Interview topics included experiences with patients on long-term treatment with either declining adherence or persistent poor adherence. Transcribed texts were coded and analyzed based on the social-ecological framework highlighting differences and commonalities between adolescents and adults.

RESULTS

The overarching themes in adolescents were unstructured treatment holidays, delays in disclosure of HIV status by caretakers, stigma, which was mainly experienced in boarding schools, and diminishing or lack of clinical support. In particular, there was minimal support for early and gradual disclosure for caretakers to the infected children, diminishing clinical support for young adults during transition to adult-based care and declining peer-to-peer support group activities. The predominating theme in adults was challenges with treatment access among temporary economic migrants. Common themes to adults and adolescents were challenges with disclosure in intimate relationships, treatment related factors including side effects, supply of single tablets in place of fixed-dose combined drugs, supply of drug brands with unfavorable taste and missed opportunities for counseling due to shortage of staff.

CONCLUSION

Adherence counseling and support should be adapted differently for adolescents and adults and to the emerging life course challenges in long-term treated patients. Programs should also address constraints experienced by temporary economic migrants to ensure continuity of treatment within the host country.

The Framing and Fashioning of Therapeutic Citizenship Among People Living With HIV Taking Antiretroviral Therapy in Uganda

In this article, we examine how people living with HIV (PLWH) were able to reconceptualize or "reframe" their understanding of HIV and enhance their capacity to self-manage the condition. Two in-depth interviews were held with 38 PLWH (20 women, 18 men) selected from three government and nongovernment antiretroviral therapy (ART) delivery sites in Wakiso District, and the narratives analyzed. ART providers played an important role in shaping participants' HIV self-management processes. Health workers helped PLWH realize that they could control their condition, provided useful concepts and language for emotional coping, and gave advice about practical self-management tasks, although this could not always be put into practice. ART providers in this setting were spaces for the development of a collective identity and a particular form of therapeutic citizenship that encouraged self-management, including adherence to ART. Positive framing institutions are important for many PLWH in resource-limited settings and the success of ART programs.

Association of knowledge on ART line of treatment, scarcity of treatment options and adherence

Background

Adherence to Antiretroviral Therapy (ART) is critical piece in the management of HIV infected patients. Despite the benefits of ART, non-adherence to ART persists. This study explores association between patient’s knowledge of the ART line of treatment, availability of future treatment options and adherence.

Methods

A cross sectional survey of HIV infected adolescent and adults was conducted. Cumulative optimal and sub-optimal adherence was defined as percentage adherence of ≥ 95 % and < 95 %, respectively. Binomial regression models were used to assess the association of patient’s knowledge of the ART line of treatment, availability of future treatment options and adherence.

Results

Of the 402 patients reviewed, 101 (25.1 %) patients knew their ART line of treatment and were aware that future treatment options are limited. Compared to those who were not aware of the ART line of treatment and/or scarcity of future treatment options, those who were aware were more likely to be adherent (adjusted prevalence ratio [APR], 1.1; 95 % CI, 1.0–1.3).

Conclusion

The study reports knowledge of patient’s ART line of treatment and future treatment options is important indicator of adherence to ART. Although majority of the patients did not have the knowledge, those who had the knowledge demonstrated to be more adherent. It is critical for the physicians/health care providers in these settings to clearly educate patients about ART line of treatment and limited availability of future treatment options as such information is likely to influence individual behavior and improve patient’s adherence to ART.

Antiretroviral therapy initiation and adherence in rural South Africa: community health workers' perspectives on barriers and facilitators

South Africa has the largest global HIV/AIDS epidemic, but barriers along the HIV care continuum prevent patients from initiating and adhering to antiretroviral therapy (ART). To qualitatively explore reasons for poor ART initiation and adherence rates from the unique perspective of community health workers (CHWs), we conducted focus groups during May-August 2014 with 21 CHWs in rural Msinga, KwaZulu-Natal. Interviews were audio-recorded, transcribed, and translated from Zulu into English. Hybrid deductive and inductive analytical methods were applied to identify emergent themes. Multiple psychosocial, socioeconomic, and socio-medical barriers acted at the level of the individual, social network, broader community, and healthcare environment to simultaneously hinder initiation of and adherence to ART. Key themes included insufficient patient education and social support, patient dissatisfaction with healthcare services, socioeconomic factors, and tension between ART and alternative medicine. Fear of lifelong therapy thwarted initiation whereas substance abuse principally impeded adherence. In conclusion, HIV/AIDS management requires patient counselling and support extending beyond initial diagnosis. Treating HIV/AIDS as a chronic rather than acute infectious disease is key to improving ART initiation and long-term adherence. Public health strategies include expanding CHWs' roles to strengthen healthcare services, provide longitudinal patient support, and foster collaboration with alternative medicine providers.

The Medical Research Council (UK)/Uganda Virus Research Institute Uganda Research Unit on AIDS--'25 years of research through partnerships'

For the past 25 years, the Medical Research Council/Uganda Virus Research Institute Uganda Research Unit on AIDS has conducted research on HIV-1, coinfections and, more recently, on non-communicable diseases. Working with various partners, the research findings of the Unit have contributed to the understanding and control of the HIV epidemic both in Uganda and globally, and informed the future development of biomedical HIV interventions, health policy and practice. In this report, as we celebrate our silver jubilee, we describe some of these achievements and the Unit's multidisciplinary approach to research. We also discuss the future direction of the Unit; an exemplar of a partnership that has been largely funded from the north but led in the south.

Association of first-line and second-line antiretroviral therapy adherence

Adherence to first-line ART is an important predictor of adherence to second-line ART. Improving adherence prior to switch is critical to improve patient outcomes.

Background

 Adherence to first-line antiretroviral therapy (ART) may be an important indicator of adherence to second-line ART. Evaluating this relationship may be critical to identify patients at high risk for second-line failure, thereby exhausting their treatment options, and to intervene and improve patient outcomes.

Methods

 Adolescents and adults (n = 436) receiving second-line ART were administered standardized questionnaires that captured demographic characteristics and assessed adherence. Optimal and suboptimal cumulative adherence were defined as percentage adherence of ≥90% and <90%, respectively. Bivariable and multivariable binomial regression models were used to assess the prevalence of suboptimal adherence percentage by preswitch adherence status.

Results

 A total of 134 of 436 (30.7%) participants reported suboptimal adherence to second-line ART. Among 322 participants who had suboptimal adherence to first-line ART, 117 (36.3%) had suboptimal adherence to second-line ART compared with 17 of 114 (14.9%) who had optimal adherence to first-line ART. Participants who had suboptimal adherence to first-line ART were more likely to have suboptimal adherence to second-line ART (adjusted prevalence ratio, 2.4; 95% confidence interval, 1.5–3.9).

Conclusions

 Adherence to first-line ART is an important predictor of adherence to second-line ART. Targeted interventions should be evaluated in patients with suboptimal adherence before switching into second-line therapy to improve their outcomes.

Higher quality of life and lower depression for people on ART in Uganda as compared to a community control group

Provision of antiretroviral treatment (ART) to people living with HIV (PLWH) has increased globally. Research measuring whether ART restores subjective well-being to "normal" levels is lacking, particularly in resource limited settings. The study objectives are to compare quality of life and depression symptoms for PLWH on ART to a general community population and to explore factors to explain these differences, including socio-economic status and the impact of urban or rural residence. PLWH on ART (n = 263) were recruited from ART delivery sites and participants not on ART (n = 160) were recruited from communities in Wakiso District, Uganda. Participants were interviewed using the translated World Health Organisation Quality of Life brief measure, the Hopkins Symptom Checklist depression section, and questions about socio-economic status, residence as urban or rural and, for PLWH on ART, self-reported adherence and use of HIV counselling. Compared to the community sample and controlling for location of residence, PLWH on ART had significantly higher quality of life (QOL) for physical, psychological and environment domains, but not the social domain. These differences were not due to socio-economic status alone. Depression scores were significantly lower for PLWH on ART. Both comparisons controlled for the effect of location of residence. People on ART self-reported high adherence and the majority had used HIV counselling services. Our findings show better QOL amongst PLWH on ART compared to a general community sample, which cannot be explained solely by differences in socio-economic status nor location of residence. The general community sample results point towards the challenges of life in this setting. Access to health services may underpin this difference and further research should explore this finding, in addition to identification of psychological mechanisms that relate to better QOL. ART provision infrastructure has clear benefits. Further work should consider sustainability and replication for other health conditions.
