Abstract
People with HIV (PWH) are at elevated risk for cardiovascular diseases (CVDs), including myocardial infarction, heart failure, and sudden cardiac death, among other CVD manifestations. Chronic immune dysregulation resulting in persistent inflammation is common among PWH, particularly those with sustained viremia and impaired CD4+ T cell recovery. This inflammatory milieu is a major contributor to CVDs among PWH, in concert with common comorbidities (such as dyslipidemia and smoking) and, to a lesser extent, off-target effects of antiretroviral therapy. In this review, we discuss the clinical and mechanistic evidence surrounding heightened CVD risks among PWH, implications for specific CVD manifestations, and practical guidance for management in the setting of evolving data.

Am J Hypertens 2024; 37:127-133. [PMID: 37777195 DOI: 10.1093/ajh/hpad087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 08/04/2023] [Accepted: 09/20/2023] [Indexed: 10/02/2023] Open
Abstract
BACKGROUND Nocturnal hypertension (NH) is a potent cardiovascular risk factor described frequently in people with HIV (PWH). Isolated NH (INH) is less well reported in PWH because of the need for ambulatory blood pressure monitoring (ABPM) in office normotensive patients. We aim to document the prevalence of NH and INH and the clinical factors associated with these phenotypes. METHODS Cross-sectional study from an HIV program in Argentina. Office and ABPM measurements, as well as clinical and laboratory exploration, were performed. We defined INH as NH with daytime normotension in patients with office normotension. RESULTS We obtained ABPM in 66 PWH, 60% male, aged 44.7 (IQR 27-69) years; 87% receiving antiretroviral therapy, and 86.2% virologically suppressed. ABPM-based hypertension prevalence was 54.7% (95% CI: 42.5-66.3). The prevalence of NH was 48.5% (32/66), while the INH prevalence was 19.7% (95% CI: 11.7-30.9). No differences were found regarding sex, HIV viral load, CD4+ T lymphocytes count, or years of infection between normotensive and INH patients. Multiple linear regression model adjusted for sex and age determined that body mass index (β = 0.93, P < 0.01), plasma uric acid (β = 0.25, P = 0.04), plasma potassium (β = -10.1, P = 0.01), and high-sensitivity C-reactive protein (hs-CRP) (β = 0.78, P = 0.02) independently predicted nocturnal systolic blood pressure (BP) in PWH. In a multiple logistic regression model adjusted for age and sex, the presence of sedentariness, plasma potassium <4 mEq/L, BMI, and hs-CRP levels were predictors of INH. CONCLUSION INH is highly prevalent in PWH. Metabolic and inflammatory markers predict nocturnal SBP in PWH.

Abstract
BACKGROUND Access to antiretroviral therapy has increased life expectancy and survival among people living with HIV (PLWH) in African countries like Nigeria. Unfortunately, non-communicable diseases such as cardiovascular diseases are on the rise as important drivers of morbidity and mortality rates among this group. The aim of this study was to explore the perspectives of key stakeholders in Nigeria on the integration of evidence-based task-sharing strategies for hypertension care (TASSH) within existing HIV clinics in Nigeria. METHODS Stakeholders representing PLWH, patient advocates, health care professionals (i.e. community health nurses, physicians and chief medical officers), as well as policymakers, completed in-depth qualitative interviews. Stakeholders were asked to discuss facilitators and barriers likely to influence the integration of TASSH within HIV clinics in Akwa Ibom, Nigeria. The interviews were transcribed, keywords and phrases were coded using the PEN-3 cultural model as a guide. Framework thematic analysis guided by the PEN-3 cultural model was used to identify emergent themes. RESULTS Twenty-four stakeholders participated in the interviews. Analysis of the transcribed data using the PEN-3 cultural model as a guide yielded three emergent themes as assets for the integration of TASSH in existing HIV clinics. The themes identified are: 1) extending continuity of care among PLWH; 2) empowering health care professionals and 3) enhancing existing workflow, staff motivation, and stakeholder advocacy to strengthen the capacity of HIV clinics to integrate TASSH. CONCLUSION These findings advance the field by providing key stakeholders with knowledge of assets within HIV clinics that can be harnessed to enhance the integration of TASSH for PLWH in Nigeria. Future studies should evaluate the effect of these assets on the implementation of TASSH within HIV clinics as well as their effect on patient-level outcomes over time.

Abstract
INTRODUCTION People with HIV (PLWH) have an increased risk myocardial infarction (MI), and evidence suggests that MI is under-diagnosed in Tanzania. However, little is known about barriers to MI care among PLWH in the region. METHODS In this qualitative study grounded in phenomenology, semi-structured interviews were conducted in northern Tanzania. Purposive sampling was used to recruit a diverse group of providers who care for PLWH and patients with HIV and electrocardiographic evidence of prior MI. Emergent themes were identified via inductive thematic analysis. RESULTS 24 physician and patient participants were interviewed. Most participants explained MI as caused by emotional shock and were unaware of the association between HIV and increased MI risk. Providers described poor provider training regarding MI, high out-of-pocket costs, and lack of diagnostic equipment and medications. Patients reported little engagement with and limited knowledge of cardiovascular care, despite high engagement with HIV care. Most provider and patient participants indicated that they would prefer to integrate cardiovascular care with routine HIV care. CONCLUSIONS PLWH face many barriers to MI care in Tanzania. There is a need for multifaceted interventions to educate providers and patients, improve access to MI diagnosis, and increase engagement with cardiovascular care among this population.

Prevalence and Factors Associated with Hypertension Among HIV Positive Patients on Antiretroviral Therapy: A Hospital-Based Cross-Sectional Study in Rwanda. Vasc Health Risk Manag 2023; 19:857-870. [PMID: 38162226 PMCID: PMC10757801 DOI: 10.2147/vhrm.s442108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 12/21/2023] [Indexed: 01/03/2024] Open
Abstract
Introduction The human immunodeficiency virus (HIV) and the use of antiretroviral therapy (ART) are influential elements contributing to hypertension, which is a public health concern particularly in sub-Saharan Africa where its underdiagnosis and limited investigation persist. Moreover, hypertension prevails at higher rates among individuals living with HIV (PLWH) in comparison to the general population. Therefore, our study determined the prevalence of hypertension and its associated factors among PLWH who are undergoing ART treatment at Byumba District Hospital. Methods A cross-sectional study design was conducted among 406 PLWH over the age of 14 years who were undergoing ART within the HIV department. We performed statistical analyses using STATA version 13. Significant independent variables identified in the bivariate analysis were further exported in a multivariable logistic regression model to ascertain their association with hypertension. This model elucidated factors associated with hypertension, presenting outcomes through odds ratios and their respective 95% confidence intervals, with statistical significance set at p < 0.05. Results The prevalence of hypertension was 24.7%, which means that roughly 1 in 4 PLWH were hypertensive. Notably, individuals aged 41 years and above demonstrated a significant association with heightened hypertension [AOR = 4.49; 95% CI = 2.45-8.21, p < 0.001] in contrast to those aged between 14 and 40 years. Additionally, smokers [AOR = 12.12; 95% CI = 4.48-32.74, p < 0.001] and individuals with a family history of hypertension [AOR = 4.28; 95% CI = 1.01-18.13, p = 0.049] demonstrated a higher likelihood of hypertension than their counterparts. Moreover, alcohol consumers [AOR = 5.5; 95% CI = 2.75-10.9, p < 0.001] had an increased likelihoods of hypertension compared to non-drinkers. Lastly, diabetics were almost 6 times more likely to be hypotensive [AOR = 4.50; 95% CI = 2.55-7.95, p = 0.018] when compared to those without diabetes. Conclusion Our findings strongly underscore the urgency for the implementation of targeted programs aimed at enhancing awareness and comprehension of the factors and potential complications tied to hypertension among PLWH. Such programs could be integrated into routine HIV care services to provide patients with the information and skills required to manage their hypertension effectively.

Abstract
OBJECTIVES We aimed to prospectively describe incident cardiovascular events among people living with HIV (PLWH) in northern Tanzania. Secondary aims of this study were to understand non-communicable disease care-seeking behaviour and patient preferences for cardiovascular care and education. DESIGN A prospective observational study. SETTING This study was conducted at the Majengo HIV Care and Treatment Clinic, an outpatient government-funded clinic in Moshi, Tanzania PARTICIPANTS: Adult patients presenting to an HIV clinic for routine care in northern Tanzania were enrolled from 1 September 2020 to 1 March 2021. INTERVENTIONS At enrolment, participants completed a survey and a resting 12-lead ECG was obtained. At 6 month follow-up, a repeat survey regarding interim health events and repeat ECG was obtained. PRIMARY AND SECONDARY OUTCOME MEASURES Interim major adverse cardiovascular events (MACE) were defined by: self-reported interim stroke, self-reported hospitalisation for heart failure, self-reported interim myocardial infarction, interim myocardial infarction by ECG criteria (new pathologic Q waves in two contiguous leads) or death due to cardiovascular disease (CVD). RESULTS Of 500 enrolled participants, 477 (95.4%) completed 6 month follow-up and 3 (0.6%) died. Over the 6 month follow-up period, 11 MACE occurred (3 strokes, 6 myocardial infarctions, 1 heart failure hospitalisation and 1 cardiovascular death), resulting in an incidence rate of 4.58 MACE per 100 person-years. Of participants completing 6 month follow-up, 31 (6.5%) reported a new non-communicable disease diagnosis, including 23 (4.8%) with a new hypertension diagnosis. CONCLUSIONS The incidence of MACE among PLWH in Tanzania is high. These findings are an important preliminary step in understanding the landscape of CVD among PLWH in Tanzania and highlight the need for interventions to reduce cardiovascular risk in this population.

Abstract
Background Non-communicable diseases (NCDs) are increasing among people living with HIV (PLHIV), especially in Sub-Saharan Africa (SSA). We determined the prevalence of NCDs and NCD risk factors among PLHIV in SSA to inform health policy makers. Methods We conducted a systematic review and meta-analysis on the prevalence of NCDs and risk factors among PLHIV in SSA. We comprehensively searched PubMed/MEDLINE, Scopus, and EBSCOhost (CINAHL) electronic databases for sources published from 2010 to July 2023. We applied the random effects meta-analysis model to pool the results using STATA. The systematic review protocol was registered on PROSPERO (registration number: CRD42021258769). Findings We included 188 studies from 21 countries in this meta-analysis. Our findings indicate pooled prevalence estimates for hypertension (20.1% [95% CI:17.5-22.7]), depression (30.4% [25.3-35.4]), diabetes (5.4% [4.4-6.4]), cervical cancer (1.5% [0.1-2.9]), chronic respiratory diseases (7.1% [4.0-10.3]), overweight/obesity (32.2% [29.7-34.7]), hypercholesterolemia (21.3% [16.6-26.0]), metabolic syndrome (23.9% [19.5-28.7]), alcohol consumption (21.3% [17.9-24.6]), and smoking (6.4% [5.2-7.7]). Interpretation People living with HIV have a high prevalence of NCDs and their risk factors including hypertension, depression, overweight/obesity, hypercholesterolemia, metabolic syndrome and alcohol consumption. We recommend strengthening of health systems to allow for improved integration of NCDs and HIV services in public health facilities in SSA. NCD risk factors such as obesity, hypercholesterolemia, and alcohol consumption can be addressed through health promotion campaigns. There is a need for further research on the burden of NCDs among PLHIV in most of SSA. Funding This study did not receive any funding.

Abstract
BACKGROUND In recent years, improved access to effective antiretroviral therapy has meant that people living with human immune virus are living longer than before. The burden of non-communicable diseases particularly, hypertension parallels with the increase in age. Although hypertension screening is thought to be an effective indicator of overall health status and paves the way for early interventions in peoples living with human immune virus, the exact prevalence of hypertension in this population remained unknown. We aimed to report the prevalence of hypertension and examine the factors associated with hypertension among people living with human immune virus in East Africa. METHODS In this systematic review and meta-analysis, we searched PubMed, Science Direct, Scopus, Cochrane library, and Google Scholar databases for studies published until January 1, 2023. The search period was from January 10/2023, to February 10/ 2023. Random-effect models were used to calculate the pooled prevalence of hypertension. Subgroup analyses were conducted to explore potential heterogeneity. The Funnel plot and Egger's test were used to assess publication bias. RESULT A total of 15 studies with 10,916 individuals were included in the present meta-analysis. The pooled prevalence of hypertension among people living with human immune virus was19.75% (95% CI, 16.07%-23.42%)),). The prevalence of hypertension was not differed between studies conducted 2014- 2019 and, studies conducted 2020-2022. The prevalence of hypertension was lowest in Ethiopia (16.13%) and highest in Tanzania (26.76%). Alcohol consumption (Adjusted Odds Ratio (AOR): 3.39, 95% CI: 2.35-4.43), diabetes (AOR: 2.64, 95% CI: 1.89-3.39), longer duration of HIV (AOR: 1.72, 95% CI: 1.15-2.3), male sex (AOR: 1.62, 95% CI: 1.43-1.8), obesity (AOR: 2.89, 95% CI: 1.94-3.84), and older age (AOR: 2.25, 95% CI: 2.0-2.5), were the factors associated with the presence of hypertension in people living with human immune virus. CONCLUSION Our study shows that one in five peoples living with human immune virus have hypertension causing symptoms and impairment, therefore requiring treatment. Designing effective health screening and hypertension management intervention programs helps to prevent the occurrence of hypertension and promotes peoples' overall quality of life.

Abstract
Data describing the incidence of hypertension and diabetes among people with HIV in sub-Saharan Africa remain sparse. In this study, adults with HIV were enrolled from a public clinic in Moshi, Tanzania (September 2020-March 2021). At enrollment, a survey was administered to collect information on comorbidities and medication use. Each participant's blood pressure and point-of-care glucose were measured. Baseline hypertension was defined by blood pressure ≥140/90 mmHg or self-reported hypertension at enrollment. Baseline diabetes was defined by self-reported diabetes or hyperglycemia (fasting glucose ≥126 mg/dl or random glucose ≥200 mg/dl) at enrollment. At 6-month follow-up, participants' blood pressure and point-of-care glucose were again measured. Incident hypertension was defined by self-report of new hypertension diagnosis or blood pressure ≥140/90 mmHg at follow-up in a participant without baseline hypertension. Incident diabetes was defined as self-report of new diabetes diagnosis or measured hyperglycemia at follow-up in a participant without baseline diabetes. During the study period, 477 participants were enrolled, of whom 310 did not have baseline hypertension and 457 did not have baseline diabetes. At six-month follow-up, 51 participants (95% CI: 38, 67) had new-onset hypertension, corresponding to an incidence of 33 new cases of hypertension per 100 person-years. Participants with incident hypertension at 6-month follow-up were more likely to have a history of alcohol use (90.2% vs. 73.7%, OR = 3.18, 95% CI:1.32-9.62, p = 0.008) and were older (mean age = 46.5 vs. 42.3, p = 0.027). At six-month follow-up, 8 participants (95% CI: 3, 16) had new-onset diabetes, corresponding to an incidence of 3 new cases of diabetes per 100 person-years. In conclusion, the incidence of elevated blood pressure and diabetes among Tanzanians with HIV is higher than what has been reported in high-income settings.

Abstract
Sub-Saharan Africa (SSA) is faced with a dual burden of hypertension and human immunodeficiency virus (HIV). In this review we sought to determine the prevalence, awareness, and control of hypertension among persons living with HIV (PLHIV), and the availability of hypertension services at the HIV care points in SSA. We searched the PubMed, Embase, Scopus, Cochrane library, Global index Medicus, African Journal online, and WHO Institutional Repository for Information Sharing (IRIS) for studies on the epidemiology of hypertension, and hypertension services for PLHIV in SSA. Twenty-six articles were identified for the review, with 150,886 participants; weighted mean of age 37.5 years and female proportion of 62.6%. The pooled prevalence was 19.6% (95% confidence interval [CI], 16.6%, 22.5%); hypertension awareness was 28.4% (95% CI, 15.5%, 41.3%), and hypertension control was 13.4% (95% CI, 4.7%, 22.1%). HIV-related factors like CD4 count, viremia, and antiretroviral therapy regimen were not consistently associated with prevalent hypertension. However, high body mass index (BMI) above 25 kg/m2 [odds ratio: 1.64, 95% CI (1.26, 2.02)] and age above 45 years [odds ratio: 1.44, 95% CI (1.08, 1.79)] were associated with prevalent hypertension. Even when PLHIV on ART were more likely to be screened for hypertension and monitored, there was infrequent screening and treatment of hypertension in most HIV clinics. Most studies recommended integrating of HIV and hypertension services. We report a high prevalence of hypertension in a relatively young population of PLHIV with suboptimal screening, treatment, and control of hypertension. We recommend strategies to integrate HIV and hypertension services.

Abstract
BACKGROUND People with HIV in sub-Saharan Africa are increasingly developing age-related comorbidities. The purpose of this prospective observational study was to describe 6-month outcomes among Tanzanians with HIV and elevated blood pressure or hyperglycemia under current care pathways. METHODS Adults presenting for routine HIV care were enrolled and underwent blood pressure and blood glucose measurements. Participants with abnormal blood pressure or glucose were referred for further care, as per current guidelines. Participants' blood pressure and point-of-care glucose were re-evaluated during their 6-month follow-up visit. Elevated blood pressure was defined as systolic ≥140 mmHg or diastolic ≥90 mmHg. Hyperglycemia was defined as fasting glucose ≥126 mg/dl or random glucose ≥200 mg/dl. An electrocardiogram was obtained at enrollment and at follow-up. Interim myocardial infarction and interim myocardial ischemia were defined as new pathologic Q waves and new T-wave inversions, respectively. RESULTS Of 500 participants, 155 had elevated blood pressure and 17 had hyperglycemia at enrolment. At 6-month follow-up, 7 (4.6%) of 155 participants with elevated blood pressure reported current use of an anti-hypertensive medication, 100 (66.2%) had persistent elevated blood pressure, 12 (7.9%) developed interim myocardial infarction, and 13 (8.6%) developed interim myocardial ischemia. Among 17 participants with hyperglycemia, 9 (56%) had persistent hyperglycemia at 6 months and 2 (12.5%) reported current use of an anti-hyperglycemic medication. CONCLUSIONS Interventions are needed to improve non-communicable disease care pathways among Tanzanians with HIV.

Abstract
BACKGROUND Sub-Saharan Africa has a high prevalence of hypertension with a low rate of awareness, treatment adherence, and control. The emergency department (ED) may represent a unique opportunity to improve hypertension screening, awareness, and linkage to care. We conducted a qualitative study among hypertensive patients presenting to the ED and their healthcare providers to determine barriers to hypertension care and control. METHODS In northern Tanzania, between November and December 2017, we conducted three focus group discussions among patients with hypertension presenting to the emergency department and three in-depth interviews among emergency department physicians. In our study, hypertension was defined as a single blood pressure of ≥160/100 mm Hg or a two-time average of ≥140/90 mm Hg. Barriers to care were identified by thematic analysis applying an inductive approach within the framework method. RESULTS We enrolled 24 total patients into three focus groups and performed three in-depth interviews with individual providers. Thematic analysis identified two major domains: 1) patient knowledge, attitudes, and practices, and 2) structural barriers to hypertension care. Four major themes emerged within the knowledge, attitudes, and practices domain, including disease chronicity, provider communication, family support, and fear-based attitudes. Within the structural domain, several themes emerged that identified barriers that impeded hypertension follow-up care and self-management, including cost, access to care, and transportation and wait time. CONCLUSION Patients and physicians identified multiple barriers and facilitators to hypertension care. These perspectives may be helpful to design emergency department-based interventions that target blood pressure control and linkage to outpatient care.

Abstract
HIV is associated with increased risk of cardiovascular disease, but there has been less study of cardiovascular comorbidities among people with HIV in sub-Saharan Africa. In a cross-sectional observational study, Tanzanian adults presenting for outpatient HIV care completed a questionnaire and underwent weight, height, blood pressure, and blood glucose measurement. Hypertension was defined by blood pressure ≥140/90 mmHg or self-reported hypertension. Uncontrolled hypertension was defined as measured blood pressure ≥140/90 mmHg. Diabetes was defined by fasting glucose ≥126 mg/dl, random glucose ≥200 mg/dl, or self-reported diabetes. Obesity was defined by body mass index ≥30 kg/m2. Multivariate logistic regression was performed to identify predictors of uncontrolled hypertension. Among 500 participants, 173 (34.6%) had hypertension, 21 (4.2%) had diabetes, and 99 (19.8%) were obese. Of those with hypertension, 116 (67.1%) were unaware of their hypertension, and 155 (89.6%) had uncontrolled hypertension. In multivariate analysis, uncontrolled hypertension was associated with older age (OR 1.07, 95% CI: 1.05-1.10, p < 0.001) and higher body mass index (OR 1.17, 95% CI: 1.11-1.22, p < 0.001). Interventions are needed to improve screening and treatment for hypertension, diabetes, and obesity among Tanzanians with HIV.

Abstract
Currently, the life expectancy of people living with the human immunodeficiency virus (HIV) and the general population are similar. Hypertension is a major public health issue in Africa and is largely underdiagnosed. Most HIV-infected individuals, especially those on Anti-Retroviral Therapy (ART) have hypertension. Our project aims to determine the prevalence of hypertension and associated factors amongst HIV-infected adults treated by ART in Burundi. A cross-sectional study was conducted among HIV-infected subjects over the age of 20, managed in five healthcare centers for people living with HIV (PLWH). The World Health Organization STEPWISE survey and anthropometric measurements were employed. Blood pressure was measured according to the ESC 2018 recommendations. 1 250 HIV-infected patients aged between 35.4 and 50.2 years were included (18.4% men). The prevalence of hypertension was 17.4% (95% CI 13.2-22.1). Approximately 47.25% of HIV patients with hypertension were previously undiagnosed. Other factors were associated with HTN, such as being overweight (OR 2.88; 95% CI 1.46-5.62), obesity (OR 2.65; 95% CI 1.27-5.55), longer duration of HIV infection: ≥ 10 years (OR 1.04; 95% CI 1.14-3.20), diabetes (OR 2.1; 95% CI 1.37-3.32) and age (OR 1.13; 95% CI 1.09-1.14). Despite their young age, almost 20% of HIV-ART treated patients had hypertension, 50% of these were undiagnosed. Blood pressure monitoring is crucial in these patients, especially those identified as high-risk, with prompt life and disability-saving interventions.

Abstract
Current care models are inadequate to address the dual epidemic of hypertension and HIV in sub‐Saharan Africa. We developed a community health worker (CHW)‐delivered educational intervention, integrated into existing HIV care to address hypertension in persons living with HIV. A detailed educational curriculum was created with five sessions: three in‐person clinic sessions and two telephone sessions. The intervention was piloted among hypertensive adults at one HIV clinic in northern Tanzania over a 4‐week period. Primary outcomes were feasibility, fidelity, and acceptability of the intervention. Secondary outcomes included hypertension care engagement and systolic and diastolic blood pressure (SBP and DBP). Among 16 eligible participants, 14 (64% women, median age of 54.5 years) were recruited into the study, and 13 (92.9%) completed all five intervention sessions. The intervention was delivered with 98.8% fidelity to the curriculum content. Hypertension care engagement improved following the intervention. At baseline, two (15.4%) participants had seen a doctor previously for hypertension, compared to 11 (84.6%) participants post‐intervention (P = .0027). No participant was using antihypertensives at baseline, compared to 10 (76.9%) post‐intervention (P = .0016). Pre‐intervention median SBP was 164 (IQR 152–170) mmHg, compared to post‐intervention SBP of 146 (IQR 134–154) mmHg (P = .0029). Pre‐intervention median DBP was 102 (IQR 86–109) mmHg, compared to post‐intervention DBP of 89 (IQR 86–98) mmHg (P = .0023). A CHW‐delivered educational intervention, integrated into existing HIV care, is feasible and holds promise in improving hypertension care engagement and reducing blood pressure. Further research is needed to evaluate the efficacy and scale‐up of our intervention.

Pan African Medical Journal. 2022;41(285). 10.11604/pamj.2022.41.285.26952. Introduction the epidemiology of non-communicable diseases (NCDs) among people living with HIV (PLHIV) in sub-Saharan Africa is poorly described. In this observational study we examined a cohort of hypertensive PLHIV in northern Tanzania and described comorbidities, cardiovascular risk, and hypertension knowledge, attitudes and practices. Methods consecutive patients attending an HIV clinic were screened for hypertension; those who met hypertension study criteria were enrolled. Participants completed a hypertension knowledge, attitudes and practices survey, and underwent height, weight, and waist circumference measurements and urine dipstick, fasting blood sugar, and lipid panel analyses. Kidney disease was defined as 1+ proteinuria, diabetes mellitus was defined as fasting glucose >126mg/dL, and 10-year atherosclerotic cardiovascular disease (ASCVD) risk was defined per the Pooled Cohorts Equations. Results of 555 screened patients, 105 met hypertension criteria and 91 (86.7%) were enrolled. The prevalence of diabetes mellitus, kidney disease, and overweight or obesity was 8.8%, 28.6%, and 86.7%, respectively. Almost all participants (n=86, 94.5%) had two or more medical comorbidities. More than half (n=39, 52.7%) had intermediate or high 10-year risk for an ASCVD event. While only 3 (3.3%) participants were able to define hypertension correctly, most would seek care at a medical facility (n=89, 97.8%) and take medication chronically for hypertension (n=79, 87.8%). Conclusion we found a high burden of medical comorbidity and ASCVD risk among hypertensive PLHIV in northern Tanzania. Integration of routine NCD screening in the HIV clinical setting, in combination with large-scale educational campaigns, has the potential to impact clinical outcomes in this high-risk population.

Abstract
BACKGROUND The burden of uncontrolled hypertension in sub-Saharan Africa (SSA) is high and hypertension is known to coexist with other chronic diseases such as kidney disease, diabetes among others. This is the first systematic review and meta-analysis to determine the burden of uncontrolled hypertension among patients with comorbidities in SSA. METHODS A comprehensive search was conducted on MEDLINE, Excerpta Medica Database (Embase) and Web of Science to identify all relevant articles published between 1 January 2000 and 17 June 2021. We included studies that reported on the prevalence of uncontrolled hypertension among people in SSA who report taking antihypertensive treatment and have another chronic condition. A random-effects meta-analysis was performed to obtain the pooled estimate of the prevalence of uncontrolled hypertension among patients with comorbid conditions while on treatment across studies in SSA. RESULTS In all, 20 articles were included for meta-analyses. Eleven articles were among diabetic patients, five articles were among patients with HIV, two were among patients with stroke while chronic kidney disease and atrial fibrillation had one article each. The pooled prevalence of uncontrolled hypertension among patients with comorbidities was 78.6% (95% CI 71.1% to 85.3%); I² 95.9%, varying from 73.1% in patients with stroke to 100.0% in patients with atrial fibrillation. Subgroup analysis showed differences in uncontrolled hypertension prevalence by various study-level characteristics CONCLUSION: This study suggests a high burden of uncontrolled hypertension in people with comorbidities in SSA. Strategies to improve the control of hypertension among people with comorbidities are needed. PROSPERO REGISTRATION NUMBER CRD42019108218.

Abstract
OBJECTIVES To describe knowledge, attitudes, and practices (KAP) regarding ischemic heart disease (IHD) among adults with HIV in Tanzania. METHODS Adults presenting for routine HIV care at a clinic in northern Tanzania were consecutively enrolled and were administered a standardised KAP survey. For each participant, an IHD knowledge score was calculated by tallying correct answers to the IHD knowledge questions, with maximum score 10. Individual 5-year risk of cardiovascular event was calculated using the Harvard NHANES model. Associations between participant characteristics and IHD knowledge scores were assessed via Welch's t-test. RESULTS Among the 500 participants, the mean (SD) age was 45.3 (11.4) years and 139 (27.8%) were males. Most participants recognised high blood pressure (n = 313, 62.6%) as a risk factor for IHD, but fewer identified diabetes as a risk factor (n = 241, 48.2%), or knew that aspirin reduces the risk of a secondary cardiovascular event (n = 73, 14.6%). Higher IHD knowledge score was associated with post-primary education (mean 6.27 vs. 5.35, p = 0.001) and with >10% 5-year risk of cardiovascular event (mean 5.97 vs. 5.41, p = 0.045). Most participants believed there were things they could do to reduce their chances of having a heart attack (n = 361, 72.2%). While participants indicated that they adhered to their prescribed medications (n = 488, 97.6%), only 106 (21.2%) attended regular health check-ups. CONCLUSION Efforts are needed to improve gaps in IHD knowledge, and increase uptake of cardiovascular preventative practices among Tanzanian adults with HIV.

Abstract
One in three people with HIV (PWH) has hypertension. However, most hypertensive PWH in sub-Saharan Africa are unaware of their hypertension diagnosis and are not on treatment. To better understand barriers to hypertension care faced by PWH, we interviewed 15 medical providers who care for patients with HIV and hypertension in northern Tanzania. The data revealed barriers at the patient, provider, and system level and included: stress, depression, and HIV-related stigma; lack of hypertension knowledge; insufficient hypertension training; inefficient prescribing practices; challenges with counselling; capacity limitations in hypertension care; high costs of care; and lack of routine hypertension screening and follow-up. Opportunities for improvement focused on prioritizing resources and funding towards hypertension care. System-related challenges were the underlying cause of barriers at individual levels. Strategies that focus on strengthening capacity and utilize existing HIV platforms to promote hypertension care delivery are urgently needed to improve cardiovascular outcomes among PWH.

"It's because I think too much": Perspectives and experiences of adults with hypertension engaged in HIV care in northern Tanzania. PLoS One 2020; 15:e0243059. [PMID: 33270765 PMCID: PMC7714125 DOI: 10.1371/journal.pone.0243059] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 11/13/2020] [Indexed: 12/13/2022] Open
Abstract
Background Hypertension, a leading risk for cardiovascular mortality, is an important co-morbidity among people living with HIV (PLHIV). In Tanzania, hypertension prevalence among PLHIV approaches 20 to 30%. However, most patients are unaware of their diagnosis and are not receiving treatment. Understanding the barriers to hypertension care is a critical first step in developing interventions to improve cardiovascular outcomes among PLHIV in Tanzania and similar settings. Methods Between September 1st and November 26th, 2018 thirteen semi structured in-depth interviews were conducted with hypertensive patients engaged in HIV care in two HIV clinics located in government health facilities in northern Tanzania. Interviews were audio-recorded, translated into English, transcribed and thematically coded using NVivo. Data analysis was conducted using applied thematic analysis. Results Participants had a median age of 54 (IQR 41–65) years. Of the 13 participants, eight stated they had used antihypertensive medication previously, but only one participant described current use of antihypertensive therapy. All participants were currently using antiretroviral therapy. The data revealed a range of themes including limited hypertension knowledge. Universally, all participants believed that “thinking too much”, i.e. stress, was the major contributor to hypertension and that by “reducing thoughts”, one may control hypertension. Additional emerging themes included a perceived overlap between hypertension and HIV, delays in hypertension diagnosis and linkage to care, challenges with provider communication and counseling, reluctance towards antihypertensive medication, lack of integration of hypertension and HIV care, and additional structural barriers to hypertension care. Conclusions Participants described multiple, intersecting challenges related to hypertension management. Barriers specific to PLHIV included siloed care, HIV-related stigma, and burden from multiple medical conditions. Multifaceted strategies that seek to address structural barriers, hypertension education, psychosocial stressors and stigma, and that are integrated within HIV care are urgently needed to improve cardiovascular outcomes among PLHIV in sub-Saharan Africa.
