IntroductionThe scale-up of integrated Human Immunodeficiency Virus (HIV) and tuberculosis (TB) treatment has been an important intervention to curb the burden of HIV and TB co-infection worldwide. Uptake of and adherence to antiretroviral therapy (ART) are key determinants of the quality and therapeutic endpoints of this intervention. This study aims to conduct an up-to-date collection and synthesis of evidence on barriers to and facilitators of uptake of and adherence to ART in HIV/TB integrated treatment programs in sub-Saharan Africa (SSA).MethodA systematic review of peer-reviewed literature on the uptake of and adherence to ART in the context of integrated therapy for HIV and TB in SSA will be performed. We will review qualitative and quantitative studies reporting on the uptake of and adherence to ART during integrated treatment for TB and HIV among adults. These will include studies that involve HIV-infected TB patients initiating ART and studies involving PLWHA already on ART who are newly diagnosed with TB. Qualitative studies, quantitative studies, randomised trials and observational studies will be included. Six databases including Medline and Embase will be searched for relevant studies published from March 2004 to July 2019. Two authors will independently screen the search output and retrieve full texts of eligible studies. Disagreements between the two authors will be resolved by arbitration by a third author. Data will be abstracted from the eligible studies and synthesis will be done through descriptive synthesis for qualitative data and meta-analysis for quantitative data.Ethics and disseminationThis study will be a review of the literature and will not involve primary collection of individuals’ data. Amendments to the protocol will be documented in the final review. The final study will be published in a peer-reviewed journal and presented at conferences. The review is expected to contribute to improving strategies to enhance uptake of and adherence to ART in integrated care.PROSPERO registration numberCRD42019131933.

Abstract Introduction Programmes that merge management of Human Immunodeficiency Virus (HIV) and tuberculosis (TB) aim to improve HIV/TB co-infected patients’ access to comprehensive treatment. However, several reports from sub-Saharan Africa (SSA) indicate suboptimal uptake of antiretroviral therapy (ART) even after integration of HIV and TB treatment. This study assessed ART uptake, its barriers and enablers in programmes integrating TB and HIV treatment in SSA. Method A systematic review was performed. Seven databases were searched for eligible quantitative, qualitative and mixed-methods studies published from March 2004 through July 2019. Random-effects meta-analysis was used to obtain pooled estimates of ART uptake. A thematic approach was used to analyse and synthesise data on barriers and enablers. Results Of 5139 references identified, 27 were included in the review: 23/27 estimated ART uptake and 10/27 assessed barriers to and/or enablers of ART uptake. The pooled ART uptake was 53% (95% CI: 42, 63%) and between-study heterogeneity was high (I2 = 99.71%, p < 0.001). WHO guideline on collaborative TB/HIV activities and sample size were associated with heterogeneity. There were statistically significant subgroup effects with high heterogeneity after subgroup analyses by region, guideline on collaborative TB/HIV activities, study design, and sample size. The most frequently described socioeconomic and individual level barriers to ART uptake were stigma, low income, and younger age group. The most frequently reported health system-related barriers were limited staff capacity, shortages in medical supplies, lack of infrastructure, and poor adherence to or lack of treatment guidelines. Clinical barriers included intolerance to anti-TB drugs, fear of drug toxicity, and contraindications to antiretrovirals. Health system enablers included good management of the procurement, supply, and dispensation chain; convenience and accessibility of treatment services; and strong staff capacity. Availability of psychosocial support was the most frequently reported enabler of uptake at the community level. Conclusions In SSA, programmes integrating treatment of TB and HIV do not, in general, achieve high ART uptake but we observe a net improvement in uptake after WHO issued the 2012 guidelines on collaborative TB/HIV activities. The recurrence of specific modifiable system-level and patient-level factors in the literature reveals key intervention points to improve ART uptake in these programmes.

Despite efforts to scale up access to antiretroviral therapy (ART), particularly at primary health care (PHC) facilities, antiretroviral therapy (ART) continues to be out of reach formany human immunodeficiency virus (HIV)-positive children in sub-Saharan Africa. In resource limited settings decentralisation of ART is required to scale up access to essential medication. Traditionally, paediatric HIV care has been provided in tertiary care facilities which have better human and material resources, but limited accessibility in terms of distance for caregivers of HIV-positive children. The focus of this article is on the experiences of caregivers whilst accessing ART for HIV-positive children at PHC (decentralised care) facilities in Nelson Mandela Bay (NMB) in the Eastern Cape, South Africa. A qualitative, explorative, descriptive and contextual research design was used. The target population comprised caregivers of HIV-positive children. Data were collected by means of indepth individual interviews, which were thematically analysed. Guba's model was usedto ensure trustworthiness. Barriers to accessing ART at PHC clinics for HIV-positive children included personal issues, negative experiences, lack of support and finance, stigma and discrimination. The researchers recommend standardised programmes be developed and implemented in PHC clinics to assist in providing treatment, care and support for HIV positive children.

Abstract Background Clinical scores to determine early (6-month) antiretroviral therapy (ART) mortality risk have not been developed for sub-Saharan Africa (SSA), home to 70% of people living with HIV. In the absence of validated scores, WHO eligibility criteria (EC) for ART care intensification are CD4 < 200/μL or WHO stage III/IV. Methods We used Botswana XPRES trial data for adult ART enrollees to develop CD4-independent and CD4-dependent multivariable prognostic models for 6-month mortality. Scores were derived by rescaling coefficients. Scores were developed using the first 50% of XPRES ART enrollees, and their accuracy validated internally and externally using South African TB Fast Track (TBFT) trial data. Predictive accuracy was compared between scores and WHO EC. Results Among 5553 XPRES enrollees, 2838 were included in the derivation dataset; 68% were female and 83 (3%) died by 6 months. Among 1077 TBFT ART enrollees, 55% were female and 6% died by 6 months. Factors predictive of 6-month mortality in the derivation dataset at p < 0.01 and selected for the CD4-independent score included male gender (2 points), ≥ 1 WHO tuberculosis symptom (2 points), WHO stage III/IV (2 points), severe anemia (hemoglobin < 8 g/dL) (3 points), and temperature > 37.5 °C (2 points). The same variables plus CD4 < 200/μL (1 point) were included in the CD4-dependent score. Among XPRES enrollees, a CD4-independent score of ≥ 4 would provide 86% sensitivity and 66% specificity, whereas WHO EC would provide 83% sensitivity and 58% specificity. If WHO stage alone was used, sensitivity was 48% and specificity 89%. Among TBFT enrollees, the CD4-independent score of ≥ 4 would provide 95% sensitivity and 27% specificity, whereas WHO EC would provide 100% sensitivity but 0% specificity. Accuracy was similar between CD4-independent and CD4-dependent scores. Categorizing CD4-independent scores into low (< 4), moderate (4–6), and high risk (≥ 7) gave 6-month mortality of 1%, 4%, and 17% for XPRES and 1%, 5%, and 30% for TBFT enrollees. Conclusions Sensitivity of the CD4-independent score was nearly twice that of WHO stage in predicting 6-month mortality and could be used in settings lacking CD4 testing to inform ART care intensification. The CD4-dependent score improved specificity versus WHO EC. Both scores should be considered for scale-up in SSA.

Neurocognitive impairment remains an important HIV-associated comorbidity despite combination antiretroviral therapy (ART). Since the advent of ART, the spectrum of HIV-associated neurocognitive disorder (HAND) has shifted from the most severe form to milder forms. Independent replication of HIV in the central nervous system despite ART, so-called cerebrospinal fluid (CSF) escape is now recognised in the context of individuals with a reconstituted immune system. This review describes the global prevalence and clinical spectrum of CSF escape, it role in the pathogenesis of HAND and current advances in the diagnosis and management. It highlights gaps in knowledge in sub-Saharan Africa where the HIV burden is greatest and discusses the implications for this region in the context of the global HIV treatment scale up.

Background: The benefits of antiretroviral therapy (ART) are undeniable: decreased morbidity and mortality, improved clinical outcomes, and decreased HIV transmission. In recent years, there have been remarkable efforts to roll out HIV support and treatment programs, resulting in ART access to nearly 4 million people in sub-Saharan Africa. However, a decisive step in improving outcomes of these programs relies on ART adherence. This study was conducted by aiming at exploring and describing the perceptions of patients on ART and treatment supporters about their roles in ART adherence. It was carried out at Oshakati ART clinic in the Intermediate Hospital Oshakati in Oshana region, Northern Namibia.Methods: The qualitative investigation was carried out on patients on ART and treatment supporters by means of unstructured interviews through convenient sampling technique. The data were analysed by content analytical method.Results: The study results from all respondents were consolidated, which gave a clear understanding regarding adherence at the ART clinic in Intermediate Hospital Oshakati. The perceptions of patients on ART and treatment supporters with regard to their role towards ART adherence were classified based on participants’ experiences into two main themes and sub-themes, including: 1) ART patients’ perceptions around their current roles in ART adherence comprise of four sub-themes of ART patients’ perceptions about taking medication daily, perceptions about collection of medicine supply and follow-up visits, perceptions about food and medication and perceptions about support in ART treatment; 2) Treatment supporters’ perceptions about their role in ART adherence consist of four sub-themes of perceptions about follow-up visits and collection of medicine, perceptions about psychosocial and emotional support, perceptions about giving food and medication and perceptions about encouraging personal hygiene.Conclusion: Patients and treatment supporters perceived adherence as an important aspect in the success of antiretroviral treatment. Giving patients correct information, personal motivation, patients understanding of treatment, traditional and religious beliefs were among other factors perceived by treatment supporters to be impacting on ART adherence.
