Progressive multifocal leucoencephalopathy (PML) is a progressive demyelinating condition resulting from infection with the John Cunningham virus and precipitated by immunocompromised states. The HIV pandemic, especially in sub-Saharan Africa, has resulted in an increase in the number of patients presenting with PML. Imaging plays an important role in diagnosis and the distribution of the disease is predominantly supratentorial. Isolated posterior fossa involvement is a rare finding with very few cases described in the literature. We present the largest case series of patients described in the literature, with isolated posterior fossa involvement of PML, in HIV-positive patients.

ObjectiveTo study the relationship between endothelial dysfunction, HIV infection, and stroke in Malawians.MethodsUsing a cross-sectional design, we measured plasma levels of intercellular adhesion molecule-1 (ICAM-1), plasminogen activator inhibitor-1 (PAI-1), vascular endothelial growth factor (VEGF), and soluble thrombomodulin (sTM) in stroke patients and controls, stratified by HIV status. These biomarkers were measured using ELISA. After dichotomization, each biomarker was used as the dependent variable in a multivariable logistic regression model. Primary independent variables included HIV and stroke status. Adjustment variables were age, sex, hypertension, diabetes mellitus, tobacco and alcohol consumption, personal/family history of stroke, antiretroviral therapy status, and hypercholesterolemia.ResultsSixty-one stroke cases (19 HIV+) and 168 controls (32 HIV+) were enrolled. The median age was 55 years (38.5–65.0) for controls and 52 years (38.0–73.0) for cases (p = 0.38). The median CD4+ T-cell count was 260.1 cells/mm3 (156.3–363.9) and 452 cells/mm3 (378.1–527.4) in HIV-infected cases and controls, respectively. HIV infection was independently associated with high levels of ICAM-1 (OR = 3.6, 95% CI: 1.3–10.6, p = 0.018) in controls but not in stroke cases even after excluding patients with a viral load >1,000 RNA copies/mL (OR = 4.1, 95% CI: 1.3–13.1, p = 0.017). There was no association between the clinical profiles of HIV-positive controls or HIV-positive stroke and high levels of PAI-1, VEGF, and sTM.ConclusionsHIV infection is associated with endothelial activation despite antiretroviral treatment. Our findings underscore the need for larger clinical cohorts to better understand the contribution of this perturbation of the endothelial function to the increasing burden of cardiovascular diseases in sub-Saharan Africa.

Abstract Background Sub-Saharan Africa (SSA) homes most of the people living with HIV/AIDS in the world. Adolescents/young people are a vulnerable population and at high risk of HIV infection. Identifying and bridging the research gaps on the disclosure of HIV-positive status among adolescents, particularly to their sexual partners, is essential to inform appropriate policy planning and implementation towards preventing HIV transmission. This study will aim to explore literature and describe the evidence on HIV-positive status disclosure among adolescents in SSA. Methods The framework provided by Arksey and O’Malley’s framework and improved by Levac and colleagues will be used to conduct a scoping review. A keyword search for relevant literature presenting evidence on HIV-positive status disclosure among adolescents in SSA will be conducted in CINAHL, PubMed, Science Direct, Google Scholar, and SCOPUS. Date limitations will be removed, but Boolean terms “AND” and “OR” as well as Medical Subject Headings terms will be included where possible and syntax modified to suit the database during the search. Additional relevant articles will be sought from the reference lists of all included studies using a snowballing method. Two reviewers will independently screen the articles at the abstract and full-text screening phases in order to reduce bias and improve the reliability of this study’s findings. A tabular form will be developed using Microsoft Word and piloted for data extraction. Thematic content analysis will be conducted, and a narrative summary of all relevant outcomes reported. Quality appraisal of the included studies for this proposed study will be performed utilizing the recent mixed methods appraisal tool. Discussion The evidence produced by this review may help inform policy and strategies to reduce the incidence of HIV infection among adolescents and improve social support for adolescents living with HIV/AIDS in SSA. It may also reveal literature gaps to guide future researches to further inform HIV policies for adolescents in SSA. Platforms such as peer review journals, policy briefs, and conferences will be used to disseminate this study’s findings.

Background The number of children living with HIV has increased worldwide, largely due to improvements in antiretroviral therapy. Most of these children are living in sub-Saharan Africa. The rate of disclosure to children of their HIV-positive status is low in low-resource countries compared to high-resource countries. Aim To explore health professionals' experiences of caring for HIV-positive children before and after their HIV-positive status was disclosed to them. The health professionals included nurses, counsellors, nutritionists, social workers, pharmacists and clinicians with at least 1 year of experience at the paediatric section of the comprehensive care centre. Methods Nine health professionals were interviewed. Findings Results revealed that there were more challenges before disclosure than after. The main challenge was communicating with the children. The children's main concerns before disclosures included the reason for treatment and its duration, and clinic follow-up. Conclusions Health professionals should be trained on the benefits of HIV disclosure to children, in order to allow for open and direct communication between healthcare providers, parents/carers and children.

There are an estimated 50,000 people who inject drugs in Tanzania, with an HIV prevalence in this population of 42%. The Integrated Methadone and Anti-Retroviral Therapy (IMAT) strategy was developed to integrate HIV services into an opioid treatment program (OTP) in sub-Saharan Africa and increase anti-retroviral therapy (ART) initiation rates. In this paper, we evaluate the IMAT strategy using an implementation science framework to inform future care integration efforts in the region. IMAT centralized HIV services into an OTP clinic in Dar Es Salaam, Tanzania: HIV diagnosis, ART initiation, monitoring and follow up. A mixed-methods, concurrent design, was used for evaluation: quantitative programmatic data and semi-structured interviews with providers and clients addressed 4 out of 5 components of the RE-AIM framework: reach, effectiveness, adoption, implementation. Results showed high reach: 98% of HIV-positive clients received HIV services; effectiveness: 90-day ART initiation rate doubled, from 41% pre-IMAT to 87% post-IMAT (p < 0.001); proportion of HIV-positive eligible clients on ART increased from 71% pre-IMAT to 98% post-IMAT (p < 0.001). There was high adoption and implementation protocol fidelity. Qualitative results informed barriers and facilitators of RE-AIM components. In conclusion, we successfully integrated HIV care into an OTP clinic in sub-Saharan Africa with increased rates of ART initiation. The IMAT strategy represents an effective care integration model to improve HIV care delivery for OTP clients.
