Barriers and facilitators for interventions to improve ART adherence in Sub-Saharan African countries: A systematic review and meta-analysis. PLoS One 2023; 18:e0295046. [PMID: 38032918 PMCID: PMC10688728 DOI: 10.1371/journal.pone.0295046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 11/14/2023] [Indexed: 12/02/2023] Open
Abstract
BACKGROUND The HIV/AIDS pandemic remains a significant public health issue, with sub-Saharan Africa (SSA) at its epicentre. Although antiretroviral therapy (ART) has been introduced to decrease new infections and deaths, SSA reports the highest incidence of HIV/AIDS, constituting two-thirds of the global new infections. This review aimed to elucidate the predominant barriers and facilitators influencing ART adherence and to identify effective strategies to enhance ART adherence across SSA. METHODS A comprehensive review was conducted on studies examining barriers to ART adherence and interventions to boost adherence among HIV-positive adults aged 15 and above in SSA, published from January 2010 onwards. The research utilized databases like Medline Ovid, CINAHL, Embase, and Scopus. Included were experimental and quasi-experimental studies, randomized and non-randomized controlled trials, comparative before and after studies, and observational studies such as cross-sectional, cohort, prospective and retrospective studies. Two independent reviewers screened the articles, extracted pertinent data, and evaluated the studies' methodological integrity using Joanna Briggs Institute's standardized appraisal tools. The compiled data underwent both meta-analysis and narrative synthesis. RESULTS From an initial pool of 12,538 papers, 45 were selected (30 for narrative synthesis and 15 for meta-analysis). The identified barriers and facilitators to ART adherence were categorized into seven principal factors: patient-related, health system-related, medication-related, stigma, poor mental health, socioeconomic and socio-cultural-related factors. Noteworthy interventions enhancing ART adherence encompassed counselling, incentives, mobile phone short message service (SMS), peer delivered behavioural intervention, community ART delivery intervention, electronic adherence service monitoring device, lay health worker lead group intervention and food assistance. The meta-analysis revealed a statistically significant difference in ART adherence between the intervention and control groups (pooled OR = 1.56, 95%CI:1.35-1.80, p = <0.01), with evidence of low none statistically significant heterogeneity between studies (I2 = 0%, p = 0.49). CONCLUSION ART adherence in SSA is influenced by seven key factors. Multiple interventions, either standalone or combined, have shown effectiveness in enhancing ART adherence. To optimize ART's impact and mitigate HIV's prevalence in SSA, stakeholders must consider these barriers, facilitators, and interventions when formulating policies or treatment modalities. For sustained positive ART outcomes, future research should target specific underrepresented groups like HIV-infected children, adolescents, and pregnant women in SSA to further delve into the barriers, facilitators and interventions promoting ART adherence.

Barriers and facilitators to ART adherence among ART non-adherence people living with HIV in Cameroon: A qualitative phenomenological study. PLoS One 2023; 18:e0291487. [PMID: 37699048 PMCID: PMC10497158 DOI: 10.1371/journal.pone.0291487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 08/07/2023] [Indexed: 09/14/2023] Open
Abstract
BACKGROUND Antiretroviral therapy (ART) needs to be taken for life with near perfect levels of adherence for it to be effective. Nonetheless, ART non-adherence is still observed in sub-Saharan African (SSA) countries such as Cameroon. The objective of this study was to assess the factors influencing non-adherence and or adherence among people living with HIV (PLWH) who have experienced non-adherence to ART in Cameroon. METHODS A descriptive qualitative study of PLWH who have experienced non-adherence with ART in Cameroon was conducted. Data were collected using in-depth interviews. Collected data were analyzed using the NVIVO 12 software. RESULTS In total, 43 participants participated in this study. The Southwest and Littoral regions each contributed 15 (34.88%) of participants, participants' mean age was 37.1 years (SD: 9.81) and majority 34 (82.93%) were females. ART adherence barriers include those related to patient (forgetfulness, business with other things, unwillingness to swallow drugs daily), medication (side effects), health service (arrogance of caregivers, occasional drug shortages at treatment centre, poor counseling of patient), stigma (fear of status disclosure), use of alternative treatment (traditional medicine, prayers and deliverance), resource limitation (limited food, limited finances), environmental/social (limited or no home support), and political instability (disruption of free circulation by ghost towns, roadblocks and gunshots in some regions). ART adherence facilitators include social support (family and peer support), aligning treatment with patient's daily routines (align ART with schedule of family members), use of reminders (phone alarm, sound of church bell), health sector/caregiver support (messages to patient, financial support, proper counseling), and patient's awareness of HIV status/ART knowledge (awareness of HIV positive status, Knowledge of ART benefits). CONCLUSION ART adherence barriers in Cameroon include those related to patient, medication, health service, stigma, use of alternative treatment, resource limitation, environmental/social, and political instability. ART adherence facilitators include social support, aligning treatment with patient's daily routines, use of reminders, health sector/caregiver support, and patient's awareness of HIV status/ART knowledge. Given these barriers and facilitators, continuous information provision and consistent support both from patients' families and caregivers are needed to improve adherence among patients. Further studies including many regions and larger samples using both in-depth and focused group discussions as well as quantitative approaches are required to uncover the burden related to ART non-adherence.

Abstract
Background The HIV/AIDS pandemic continues to be a major public health concern, particularly in Sub-Saharan Africa (SSA). Despite efforts to reduce new infections and deaths with the use of antiretroviral therapy (ART), SSA countries continue to bear the heaviest burden of HIV/AIDS globally, accounting for two-thirds of global new infections. The goal of this review is to identify common barriers to ART adherence as well as common effective interventions that can be implemented across SSA countries to improve ART adherence. Methods A systematic review of published studies on adult HIV-positive patients aged 15 or above, that have assessed the barriers to ART adherence and interventions improving patients’ adherence to ART in SSA countries shall be conducted. We will conduct electronic searches for articles that have been published starting from January 2010 onwards. The databases that shall be searched will include Medline Ovid, CINAHL, Embase, and Scopus. The review will include experimental and quasi-experimental studies such as randomized and non-randomized controlled trials as well as comparative before and after studies, and observational studies—cross-sectional studies, cohort studies, prospective and retrospective studies. Two independent reviewers will screen all identified studies, extract data and appraise the methodological quality of the studies using standard critical appraisal tools from the Joanna Briggs Institute. The extracted data will be subjected to a meta-analysis and narrative synthesis. Discussion This review will synthesize existing evidence on ART adherence barriers and strategies for improving patient adherence to ART in SSA countries. It will identify common barriers to adherence and common interventions proven to improve adherence across SSA. We anticipate that the findings of this review will provide information policy makers and stakeholders involved in the fight against HIV, will find useful in deriving better ways of not only retaining patients on treatment but having them adhere to their treatment. Review registration This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO); registration number CRD42021262256.

Abstract
Researchers studying the mental health implications of HIV continue to conflate institutional mistrust (i.e., medical and/or governmental) with HIV conspiracy theory belief despite a multitude of existing scales that measure both independently. Although this conflation is made frequently, measuring for HIV conspiracy theory belief in select (largely black) populations while choosing to forgo a scale for the assessment of institutional mistrust is likewise a fairly common practice. Therefore, research done on the prevalence of HIV conspiracy theories in black populations ought to be scrutinized for bias. By doing so, the differences and similarities of these phenomena would be clarified and perhaps the way could be paved for a new HIV conspiracy theory belief scale that factors in the Internet's profound effect on conspiracy theory dissemination while ensuring the ethical practice of HIV-related research in the future.

HIV late presentation and advanced HIV disease among patients with newly diagnosed HIV/AIDS in Southwestern China: a large-scale cross-sectional study. AIDS Res Ther 2019; 16:6. [PMID: 30876476 PMCID: PMC6420760 DOI: 10.1186/s12981-019-0221-7] [Citation(s) in RCA: 49] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Accepted: 03/02/2019] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE This study aimed to investigate the prevalence of HIV late presentation and advanced HIV disease and to identify the factors associated with HIV late presentation and advanced HIV disease among patients with newly diagnosed HIV/AIDS in the Guangxi Zhuang Autonomous Region, in Southwestern China. METHODS Patients with newly diagnosed HIV registered in the HIV surveillance system of Guangxi Centers for Disease Control between January 2012 and December 2016 were included in this study. RESULTS Of 45,118 newly diagnosed patients, 70.2% had late presentation, and 45.1% had advanced HIV disease. A higher prevalence of late presentation and advanced HIV disease was found in male heterosexuals and female people who use drugs (PWID). Heterosexuals (OR 2.11 [95% CI 1.90-2.34]) and PWID (OR 1.55 [95% CI 1.30-1.84]) had a higher risk of late presentation than men who have sex with men (MSM). Blood testing of the blood receivers (OR 1.75 [95% CI 1.36-2.26]) and diagnosed in hospital (OR 1.74 [95% CI 1.65-1.84]) had an increased risk of late presentation compared to those who diagnosis in voluntary counseling and testing (VCT). Heterosexuals (OR 2.86 [95% CI 2.51-3.27]), PWID (OR 2.23 [95% CI 1.83-2.71]), blood testing of the blood receivers (OR 1.58 [95% CI 1.29-1.94]) and diagnosed in hospital (OR 1.85 [95% CI 1.76-1.94]) were also independent risk factors associated with advanced HIV disease. Older age, lower level of education and being divorced or widowed were also associated with late presentation and advanced HIV disease. CONCLUSIONS Late presentation and advanced HIV disease were very common among patients with newly diagnosed HIV in Guangxi, China during 2012-2016. Targeted programs are urgently required to reduce HIV late diagnosis in Guangxi, especially for male heterosexuals, PWID, and patients with characteristics such as older age, lower level of education, divorced or widowed.

Exploring 'generative mechanisms' of the antiretroviral adherence club intervention using the realist approach: a scoping review of research-based antiretroviral treatment adherence theories.

[PMID: 28472938 PMCID: PMC5418699 DOI: 10.1186/s12889-017-4322-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Accepted: 04/27/2017] [Indexed: 01/30/2023] Open
Abstract
Background Poor retention in care and non-adherence to antiretroviral therapy (ART) continue to undermine the success of HIV treatment and care programmes across the world. There is a growing recognition that multifaceted interventions – application of two or more adherence-enhancing strategies – may be useful to improve ART adherence and retention in care among people living with HIV/AIDS. Empirical evidence shows that multifaceted interventions produce better results than interventions based on a singular perspective. Nevertheless, the bundle of mechanisms by which multifaceted interventions promote ART adherence are poorly understood. In this paper, we reviewed theories on ART adherence to identify candidate/potential mechanisms by which the adherence club intervention works. Methods We searched five electronic databases (PubMed, EBSCOhost, CINAHL, PsycARTICLES and Google Scholar) using Medical Subject Headings (MeSH) terms. A manual search of citations from the reference list of the studies identified from the electronic databases was also done. Twenty-six articles that adopted a theory-guided inquiry of antiretroviral adherence behaviour were included for the review. Eleven cognitive and behavioural theories underpinning these studies were explored. We examined each theory for possible ‘generative causality’ using the realist evaluation heuristic (Context-Mechanism-Outcome) configuration, then, we selected candidate mechanisms thematically. Results We identified three major sets of theories: Information-Motivation-Behaviour, Social Action Theory and Health Behaviour Model, which explain ART adherence. Although they show potential in explaining adherence bebahiours, they fall short in explaining exactly why and how the various elements they outline combine to explain positive or negative outcomes. Candidate mechanisms indentified were motivation, self-efficacy, perceived social support, empowerment, perceived threat, perceived benefits and perceived barriers. Although these candidate mechanisms have been distilled from theories employed to explore adherence to ART in various studies, the theories by themselves do not provide an explanatory model of adherence based on the realist logic. Conclusions The identified theories and candidate mechanisms offer possible generative mechanisms to explain how and why patients adhere (or not) to antiretroviral therapy. The study provides crucial insights to understanding how and why multifaceted adherence-enhancing interventions work (or not). These findings have implications for eliciting programme theories of group-based adherence interventions such as the adherence club intervention.

Abstract
The DC-SIGN receptor on human dendritic cells interacts with HIV gp120 to promote both infection of antigen-presenting cells and transinfection of T cells. We hypothesized that in DC-SIGN-expressing cells, both DC-SIGN ligands such as dextrans and gp120 antagonists such as peptide triazoles would inhibit HIV infection with potential complementary antagonist effects. To test this hypothesis, we evaluated the effects of dextran (D66), isomaltooligosaccharides (D06), and several peptide triazoles (HNG156, K13, and UM15) on HIV infection of B-THP-1/DC-SIGN cells. In surface plasmon resonance competition assays, D66 (IC50 = 35.4 μM) and D06 (IC50 = 3.4 mM) prevented binding of soluble DC-SIGN to immobilized mannosylated bovine serum albumin (BSA). An efficacious dose-dependent inhibition of DC-SIGN-mediated HIV infection in both pretreatment and posttreatment settings was observed, as indicated by inhibitory potentials (EC50) [D66 (8 μM), D06 (48 mM), HNG156 (40 μM), UM15 (100 nM), and K13 (25 nM)]. Importantly, both dextrans and peptide triazoles significantly decreased HIV gag RNA levels [D66 (7-fold), D06 (13-fold), HNG156 (7-fold), K-13 (3-fold), and UM15 (6-fold)]. Interestingly, D06 at the highest effective concentration showed a 14-fold decrease of infection, while its combination with 50 μM HNG156 showed a 26-fold decrease. Hence, these compounds can combine to inactivate the viruses and suppress DC-SIGN-mediated virus-cell interaction that as shown earlier leads to dendritic cell HIV infection and transinfection dependent on the DC-SIGN receptor.

Abstract
BACKGROUND Late diagnosis and presentation to human immune deficiency virus (HIV)/acquired immune deficiency syndrome care reduce the benefits of antiretroviral therapy and increase the risk of HIV transmission. OBJECTIVES This study was conducted to identify determinants of late presentation to HIV care among people living with HIV in Southern Tigray, Northern Ethiopia. METHODS An institution based un-matched case-control (1:2 ratios) supported with qualitative data was conducted in Southern Tigray Zone from March 1 to April 30, 2014. Individuals with HIV enrolled from six randomly selected health facilities were included in the study. Cases were people living with HIV who had cluster of differentiation four count <350 cells/μl or World Health Organization stages 3 or 4. A total of 442 study participants were included by systematic sampling techniques. Bivariable and multivariable binary logistic regression model was used to identify associated factors. Odds ratio with 95 % CI was computed to assess the strength of the associations. RESULT Age categories, 25-29 years [AOR 3, 95 % CI (1.2-8.1)] and 35-39 years [AOR 4.1, 95 % CI (1.4-12.5)], having two [AOR 6, 95 % CI (1.3-28)] and more [AOR 5.2, 95 % CI (1.1-24.8)] lifetime sexual partners, poor social support [AOR 2.3, 95 % CI (1.26-4.30)], second (next to lowest) wealth quintile [AOR 3.3, 95 % CI 91.3-8.5)], fear of stigma [AOR 4.4, 95 % CI (2.2-8.3)], fear of losing job [AOR 6.8, 95 % CI (1.8-24.5)], and reported severe illness [AOR 4.3, 95 % CI (2.26-8)] were identified to be the risk factors for late presentation. CONCLUSION Low socio-economic status and social support, fear of stigma were potential risk factors for late presentation. Efforts towards promoting early care seeking should target on these factors in the study area and other similar settings.

Abstract
The first six months of HIV care and treatment are very important for long-term outcome. Early mortality (within 6 months of care initiation) undermines care and treatment goals. This study assessed the temporal distribution in baseline characteristics and early mortality among HIV patients at the University College Hospital, Ibadan, Nigeria from 2006-2013. Factors associated with early mortality were also investigated. This was a retrospective analysis of data from 14 857 patients enrolled for care and treatment at the adult antiretroviral clinic of the University College Hospital, Ibadan, Nigeria. Effects of factors associated with early mortality were summarised using a hazard ratio with a 95% confidence interval obtained from Cox proportional hazard regression models. The mean age of the subjects was 36.4 (SD=10.2) years with females being in the majority (68.1%). While patients' demographic characteristics remained virtually the same over time, there was significant decline in the prevalence of baseline opportunistic infections (2006-2007=55.2%; 2011-2013=38.0%). Overall, 460 (3.1%) patients were known to have died within 6 months of enrollment in care/treatment. There was no significant trend in incidence of early mortality. Factors associated with early mortality include: male sex, HIV encephalopathy, low CD4 count (< 50 cells), and anaemia. To reduce early mortality, community education should be promoted, timely access to care and treatment should be facilitated and the health system further strengthened to care for high risk patients.

Abstract
The widespread roll-out of antiretroviral therapy (ART) has substantially changed the face of human immunodeficiency virus (HIV). Timely initiation of ART in HIV-infected individuals dramatically reduces mortality and improves employment rates to levels prior to HIV infection. Recent findings from several studies have shown that ART reduces HIV transmission risk even with modest ART coverage of the HIV-infected population and imperfect ART adherence. While condoms are highly effective in the prevention of HIV acquisition, they are compromised by low and inconsistent usage; male medical circumcision substantially reduces HIV transmission but uptake remains relatively low; ART during pregnancy, delivery and breastfeeding can virtually eliminate mother-to-child transmission but implementation is challenging, especially in resource-limited settings. The current HIV prevention recommendations focus on a combination of preventions approach, including ART as treatment or pre- or post-exposure prophylaxis together with condoms, circumcision and sexual behaviour modification. Improved survival in HIV-infected individuals and reduced HIV transmission risk is beginning to result in limited HIV incidence decline at population level and substantial increases in HIV prevalence. However, achievements in HIV treatment and prevention are threatened by the challenges of lifelong adherence to preventive and therapeutic methods and by the ageing of the HIV-infected cohorts potentially complicating HIV management. Although current thinking suggests prevention of HIV transmission through early detection of infection immediately followed by ART could eventually result in elimination of the HIV epidemic, controversies remain as to whether we can treat our way out of the HIV epidemic.
