Abstract Purpose: In 2016, Malawi implemented a universal test and treat (UTT) policy, expanding eligibility for antiretroviral therapy (ART) to anyone with confirmed HIV infection. Prior to 2016, Malawi restricted ART initiation to HIV-positive individuals with CD4 count ≤500 cells/µL, with WHO staging ≥III who were pregnant or breastfeeding, or who were younger than 5 years old. Here, we assess the impact on distribution of lymphoma presentation and baseline clinical characteristics at Kamuzu Central Hospital, Lilongwe, Malawi. Methods: Participants with newly diagnosed, pathologically confirmed lymphoproliferative disorders were enrolled from 2013 - 2020. We categorized participants as pre-universal ART (pre-UART) if enrolled during 2013-June 2016 or post-universal ART (post-UART) if enrolled during July 2016-2020 and evaluated clinical characteristics. Findings: Of 412 total participants, 156 were pre-UART and 256 were post-UART. The most common diagnoses were diffuse large B-cell lymphoma (DLBCL) (45%), low-grade lymphoma (11%), Burkitt lymphoma (10%), Hodgkin lymphoma (9%), and multicentric Castleman disease (7%) and there was no significant difference in distribution of diagnoses between pre-UART and post-UART periods (Figure 1). HIV prevalence was 50%, mean age 43, and 62% male. Sixty-six percent (48/73) of pre-UART HIV-positive participants knew their HIV status, for median 5 years (IQR 2-8) and 71% (41/58) were on ART for median 4 years (IQR 2-7). Eighty percent (94/117) of post-UART HIV positive participants knew their HIV status (p=0.02), for median 4 years (IQR 2-9) and 84% (89/106) were on ART (p=0.05) for median 4 years (IQR 2-8). HIV was suppressed <1000 copies/mL in 56% (33/59) pre-UART and 71% (73/103) post-UART (p=0.05). Among DLBCL participants, 61% (23/38) of pre-UART HIV-positive participants knew their HIV status, for median 5 years (IQR 2-9), 61% (19/31) were on ART for median 4 years (IQR 2-6). Eighty-two percent (n=51/63) of post-UART DLBCL HIV-positive participants knew their HIV status (p=0.02) for median 5 years (IQR 2-9) and 89% (47/53) were on ART (p < 0.01) for median 5 years (IQR 2-9). Post-UART DLBCL participants had median HIV viral load of 0 log copies/mL (IQR 0-10) compared to pre-UART (6.2; IQR 0-10) (p=0.09). CD4 count, age adjusted-IPI and Ki67 proliferation index were similar for DLBCL patients in the two groups. Interpretation: There were no significant differences in lymphoma subtypes diagnosed or in traditional DLBCL prognostic factors after implementation of universal ART in Malawi. However, HIV was better controlled in the post-UART period and differences in immunological status may have implications for therapy and prognosis. Strengths of this study include a deeply characterized cohort, both clinically and pathologically. As opposed to epidemiological data from the US and Europe, we did not see a major shift in diagnoses over this time period with increasing access to ART. However, possible explanations for the differences include that this is not a epidemiological survey as cancer registration data is not comprehensively collected in Malawi and that the roll out of ART across sub-Saharan Africa has been much more gradual than the abrupt increase in access that was seen in the US and Europe. Therefore, epidemiological chances may also be more gradual. In summary, this is some of the most comprehensive data on lymphoma presentation from sub-Saharan Africa across periods of increasing access to ART and despite improved HIV control among incident lymphoma cases, there was no change in the distribution of diagnoses in this time period.

BackgroundSuicide is a leading cause of death for young people. Children living in sub-Saharan Africa, where HIV rates are disproportionately high, may be at increased risk.AimsTo identify predictors, including HIV status, of suicidal ideation and behaviour in Rwandan children aged 10–17.MethodMatched case–control study of 683 HIV-positive, HIV-affected (seronegative children with an HIV-positive caregiver), and unaffected children and their caregivers.ResultsOver 20% of HIV-positive and affected children engaged in suicidal behaviour in the previous 6 months, compared with 13% of unaffected children. Children were at increased risk if they met criteria for depression, were at high-risk for conduct disorder, reported poor parenting or had caregivers with mental health problems.ConclusionsPolicies and programmes that address mental health concerns and support positive parenting may prevent suicidal ideation and behaviour in children at increased risk related to HIV.

Background: In many countries in Sub-Saharan Africa, self-reported HIV testing history and awareness of HIV-positive status from household surveys are used to estimate the percentage of people living with HIV (PLHIV) who know their HIV status. Despite widespread use, there is limited empirical information on the sensitivity of those self-reports, which can be affected by non-disclosure. Methods: Bayesian latent class models were used to estimate the sensitivity of self-reported HIV testing history and awareness of HIV-positive status in four Population-based HIV Impact Assessment surveys in Eswatini, Malawi, Tanzania, and Zambia. Antiretroviral (ARV) metabolites biomarkers were used to identify persons on treatment who did not accurately report their status. For those without ARV biomarkers, the pooled estimate of non-disclosure among untreated persons was 1.48 higher than those on treatment. Results: Among PLHIV, the sensitivity of self-reported HIV testing history ranged 96% to 99% across surveys. Sensitivity of self-reported awareness of HIV status varied from 91% to 97%. Non-disclosure was generally higher among men and those aged 15-24 years. Adjustments for imperfect sensitivity did not substantially influence estimates of of PLHIV ever tested (difference <4%) but the proportion of PLHIV aware of their HIV-positive status was higher than the unadjusted proportion (difference <8%). Conclusions: Self-reported HIV testing histories in four Eastern and Southern African countries are generally robust although adjustment for non-disclosure increases estimated awareness of status. These findings can contribute to further refinements in methods for monitoring progress along the HIV testing and treatment cascade.

Background Multiple Sclerosis (MS) is the leading cause of non-traumatic neurological disability in young adults. There is limited literature regarding the burden of MS in sub-Saharan Africa (SSA). Objective To describe the demographic and clinical characteristics of patients with MS (PwMS) presenting to a tertiary referral hospital in Nairobi. Methods We conducted a retrospective descriptive study for PwMS presenting to Aga Khan University Hospital, Nairobi from 2008–2018. Results 99 cases met the diagnostic criteria for MS with a male to female ratio of 1:4. Majority (68.7%) of PwMS were indigenous Africans with a mean age of onset of 30.7 years. Mean duration from symptom onset to first neuro-imaging was 5.04 years. Only 33% of patients had sensory symptoms at onset whereas 54.5% had vitamin D deficiency/insufficiency. Majority (79.5%) had relapsing remitting MS (RRMS) and 56.6% were initiated on disease modifying therapy (DMT). Only 21.2% of patients on DMT were non-compliant. Patients with RRMS were more likely to be initiated on DMT at our hospital (p < 0.001). Conclusion Clinical characteristics of these patients largely resemble those of other SSA cohorts and African American patients. There was a delay between symptom onset and neuroimaging. There were also issues with DMT compliance.

Abstract Background Tuberculosis (TB) is one of the oldest diseases known to man, yet the world health organization reports that TB is one of the top 10 causes of death worldwide. HIV infection is the most potent biologic risk factor for developing tuberculosis. The HIV epidemic has been responsible for increasing the burden of TB worldwide and The Bahamas has been no exception. The aim of this study was to determine the HIV testing rate as well as prevalence of TB-HIV coinfection for The Bahamas and compare cases of TB based on HIV status for clinical presentation, radiologic findings, TST results and Smear and Culture results. We also evaluated cases of TB-HIV for degree of immunosuppression and compliance to antiretroviral therapy. Methods A retrospective chart review of cases of Tuberculosis diagnosed at the Princess Margaret Hospital, Nassau, Bahamas. 189 cases of active tuberculosis diagnosed between 2014 and 2016 and all cases were evaluated for demographics, risk factors, HIV status, clinical manifestation, radiologic findings, and smear and culture results. Results Of the 189 cases of notified tuberculosis between 2014 and 2016, 109 (59.9%) were HIV negative and 73 (40.1%) were HIV positive. For patients who were HIV positive, 54(74%) were previously diagnosed with HIV and 19(26%) were newly diagnosed. Of the patients who were previously diagnosed with HIV, 14(25.9%) were on antiretroviral (ARV) medications and compliant, 34(63.0%) were on ARVs and noncompliant and 6(11.1%) were not on ARVs. 4(8.2%) patient had a CD4 count ≥500, 8(16.3%) patients had a CD4 count between 499–200 and 37(75.5%) had a CD4 counts 1000. Conclusion HIV is a major risk factor for Tuberculosis in the Bahamas and it is advised that all patients diagnosed with TB be tested for HIV. Routine screening of HIV patients for TB is recommended. Noncompliance with antiretroviral therapy remains a public health issue as it increases susceptibility to TB infection. Disclosures All authors: No reported disclosures.

Nigeria is one of the high-burden countries in sub-Saharan Africa for HIV/AIDS and contributes to reproductive health morbidities and mortalities. This study was aimed at determining the prevalence of HIV-discordant rate among pregnant women in Plateau state Nigeria. The study sought to determine the prevalence and trend of HIV sero-discordance among pregnant women in Plateau state, Nigeria. The study was a 5-year descriptive analysis of HIV sero-discordance among pregnant women accessing prenatal care and their partners in Plateau state, Nigeria based on data generated between January 2012 and December 2016. The data was disaggregated by year, HIV concordant negative, HIV concordant positive, and HIV sero-discordant prevalence in the software and analysis were done using excel to obtained the proportions and trend of HIV sero-discordant prevalence among the antenatal population. Out of a total of 7,851 partners of pregnant women studied, 969 (16.3%) were HIV sero-discordant, 5,795 (73.8%) were HIV concordant negative, and 773 (9.9%) were HIV concordant positive. HIV sero-discordant positive males accounted for 12.3% while females were 4.0%. The prevalence of HIV sero-discordance was low with a high proportion of HIV positive male partners in Plateau state with grave public health implications for new HIV infections among partners and eroding the gains made in the Prevention of mother-to-child transmission of HIV.

Abstract Background: Very few studies in the literature describe adult-onset vernal keratoconjunctivitis (VKC). HIV has many associated ocular pathologies and an association with VKC has not been described yet. The aim is to identify and describe patients who present with new-onset VKC after puberty, with no prior history of atopic diseases or allergies. Methods: The study consisted of two parts: the first part was a prospective observational descriptive study of patients with adult-onset VKC, detailing the epidemiological and demographic characteristics of these patients, including their HIV status. The second was a case-control study to determine the relationship of a CD4 count with adult-onset VKC in the setting of HIV. Patients were recruited between January 2016 and November 2017 from McCord Provincial Eye hospital, one of two large referral hospitals for the province of KwaZulu-Natal, South Africa. Patients presenting to the Eye clinic were screened at the Primary Eye Care Unit. Inclusion criteria were age 15 years and older with signs and symptoms of new-onset VKC. Exclusion criteria were a history of childhood atopic diseases, atopic keratoconjunctivitis and patients who refused HIV testing. Data collected included HIV status, CD4 count where appropriate, anti-nuclear antibodies and total serum immunoglobulin E. Results: 33 patients were included in this study; females n=16, males n=17. The mean age at presentation was 32.45±9.93 years, 95% CI=28.94-35.97. All of the patients were black Africans. One patient tested ANA positive. 51.5% of patients had a raised IgE level. A total of 13 of 25 HIV positive patients (52%) had a raised IgE. The proportion of HIV positive patients was statistically different from the HIV negative group, with Chi-squared = 21.866, p-value <0.0001. 72% of the HIV positive patients were grouped as immunodeficient according to their CD4 counts. An association was proven between severely immunodeficient patients and the risk of having VKC (chi-squared=4.992, p-value=0.0255). Conclusion: In this cohort a statistically significant association was found between adult-onset vernal keratoconjunctivitis and an HIV positive status. This association calls for more research on the subject, but could imply that patients presenting with adult-onset VKC should be offered an HIV test. Key words: Vernal keratoconjunctivitis, New-onset VKC Adult-onset VKC Ocular manifestations of HIV Allergy Immunocompromised.

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.
