RESUMO

Background: COVID-19 cardiovascular research from Africa is limited. This study describes cardiovascular risk factors, manifestations, and outcomes of patients hospitalised with COVID-19 in the African region, with an overarching goal to investigate whether important differences exist between African and other populations, which may inform health policies. Methods: A multinational prospective cohort study was conducted on adults hospitalised with confirmed COVID-19, consecutively admitted to 40 hospitals across 23 countries, 6 of which were African countries. Of the 5,313 participants enrolled globally, 948 were from African sites (n = 9). Data on demographics, pre-existing conditions, clinical outcomes in hospital (major adverse cardiovascular events (MACE), renal failure, neurological events, pulmonary outcomes, and death), 30-day vitality status and re-hospitalization were assessed, comparing African to non-African participants. Results: Access to specialist care at African sites was significantly lower than the global average (71% vs. 95%), as were ICU admissions (19.4% vs. 34.0%) and COVID-19 vaccination rates (0.6% vs. 7.4%). The African cohort was slightly younger than the non-African cohort (55.0 vs. 57.5 years), with higher rates of hypertension (48.8% vs. 46.9%), HIV (5.9% vs. 0.3%), and Tuberculosis (3.6% vs. 0.3%). In African sites, a higher proportion of patients suffered cardiac arrest (7.5% vs. 5.1%) and acute kidney injury (12.7% vs. 7.2%), with acute kidney injury (AKI) appearing to be one of the strongest predictors of MACE and death in African populations compared to other populations. The overall mortality rate was significantly higher among African participants (18.2% vs. 14.2%). Conclusions: Overall, hospitalised African patients with COVID-19 had a higher mortality despite a lower mean age, contradicting literature that had previously reported a lower mortality attributed to COVID-19 in Africa. African sites had lower COVID-19 vaccination rates and higher AKI rates, which were positively associated with increased mortality. In conclusion, African patients were hospitalized with more severe COVID-19 cases and had poorer outcomes.

RESUMO

Objectives: Risk stratification is a cornerstone for preventing atherosclerotic cardiovascular disease (ASCVD). Ghana has yet to develop a locally derived and validated ASCVD risk model. A critical first step towards this goal is assessing how the commonly available risk models perform in the Ghanaian population. This study compares the agreement and correlation between four ASCVD risk assessment models commonly used in Ghana. Methods: The Ghana Heart Study collected data from four regions in Ghana (Ashanti, Greater Accra, Northern, and Central regions) and excluded people with a self-declared history of ASCVD. The 10-year fatal/non-fatal ASCVD risk of participants aged 40-74 was calculated using mobile-based apps for Pooled Cohort Equation (PCE), laboratory-based WHO/ISH CVD risk, laboratory-based Framingham risk (FRS), and Globorisk, categorizing them as low, intermediate, or high risk. The risk categories were compared using the Kappa statistic and Spearman correlation. Results: A total of 615 participants were included in this analysis (median age 55 [Inter quartile range 46, 64]) years with 365 (59.3 %) females. The WHO/ISH risk score categorized 504 (82.0 %), 58 (9.4 %), and 53 (8.6 %) as low-, intermediate-, and high-risk, respectively. The PCE categorized 345 (56.1 %), 181 (29.4 %), and 89 (14.5 %) as low-, intermediate- and high-risk, respectively. The Globorisk categorized 236 (38.4 %), 273 (44.4 %), and 106 (17.2 %) as low-, intermediate-, and high-risk, respectively. Significant differences in the risk categorization by region of residence and age group were noted. There was substantial agreement between the PCE vs FRS (Kappa = 0.8, 95 % CI 0.7 - 0.8), PCE vs Globorisk (Kappa = 0.6; 95 % CI 0.6 - 0.7), and FRS vs Globorisk (Kappa = 0.6; 95 % CI 0.6 - 0.7). However, there was only fair agreement between the WHO vs Globorisk (Kappa = 0.3; 95 % CI 0.3-0.4) and moderate agreement between the WHO vs PCE and WHO vs FRS. Conclusion: There are significant differences in the ASCVD risk prediction tools in the Ghanaian population, posing a threat to primary prevention. Therefore, there is a need for locally derived and validated tools.

RESUMO

BACKGROUND: Lifestyle behavioural risk factors have been linked to increased cardiovascular disease. Recent data have shown increased atherosclerotic cardiovascular disease (ASCVD) burden in Ghana. This study aimed to describe the behavioural and nutritional risk factors for ASCVD among Ghanaians, and how these risk factors vary by ethnicity, demography and residence. METHODS: We used data from the Ghana Heart Study, a community-based cross-sectional study that recruited participants from eight communities from four regions using a multi-stage sampling technique. Information about various lifestyle behaviours (LBs), including cigarette smoking, alcohol intake, physical inactivity, and fruit and vegetable intake, was obtained using a questionnaire. Data was analysed using IBM SPSS statistics 25. Univariate and multivariate analysis was used to test associations between demographic characteristics and various LBs. RESULTS: The participants' median (interquartile) age was 46.0 (27.0) years. Of the 1,106 participants (58% females, 80.4% urban dwellers), 8.6% reported using tobacco, 48.9% alcohol, 83.7% physically inactive, 81.4% and 84.9% inadequate fruit and vegetable intake, respectively. Age, sex, ethnicity, and religion were associated with tobacco use, whereas age, sex, educational level, marital status, ethnicity, employment status, and region of residence were associated with physical inactivity. Similarly, ethnicity, employment status, and residence region were associated with inadequate fruit and vegetable intake. Rural dwellers were more likely to be physically inactive and consume inadequate fruits and vegetables. Almost 92% had a combination of two or more LBs. The main predictors of two or more LBs for ASCVD were educational level, marital status, ethnicity, and employment status. CONCLUSION: Lifestyle risk factors for ASCVD were highly prevalent in Ghana, with significant age, sex, ethnic, and regional differences. These risky lifestyle behaviors tend to occur together and must be considered in tailoring public health education. TRIAL REGISTRATION: The study was registered at http://www.chictr.org.cn as ChiCTR1800017374.

RESUMO

BACKGROUND: Sub-valvular aortic stenosis is a rare disorder that has a prevalence of 6.5% of all adult congenital heart diseases. The hemodynamic changes that occur in pregnancy with the resultant increase in cardiac output may not well be tolerated by a pregnant woman with sub-valvular aortic stenosis. CASE PRESENTATION: We report the case of a 34-year-old para 7 (6 alive + 1 dead) who has been experiencing intermittent episodes of easy fatigability on moderate exertion since childhood and had survived 6 prior pregnancies. During her last pregnancy, she started experiencing chest pain, palpitations, dyspnea, orthopnea, and pre-syncope at 36 weeks and had a caesarean section at 37 weeks on account of fetal distress. The post-delivery cardiac evaluation showed severe sub-valvular Aortic stenosis and a ventricular septal defect. CONCLUSION: Sub-valvular Aortic stenosis may progress slowly in adults and may be tolerated during pregnancy. Despite the rare presentation and contraindication of pregnancy in such a patient, she extraordinarily survived the pregnancy with a healthy baby. Routine cardiovascular assessment during prenatal, ante-natal and post-natal care is highly advocated particularly so in resource-poor settings.

RESUMO

PURPOSE: To develop and validate a health-related quality of life (HRQoL) questionnaire for patients with current or previous coronavirus disease (COVID-19) in an international setting. METHODS: This multicenter international methodology study followed standardized guidelines for a four-phase questionnaire development. Here, we report on the pretesting and validation of our international questionnaire. Adults with current or previous COVID-19, in institutions or at home were eligible. In the pretesting, 54 participants completed the questionnaire followed by interviews to identify administration problems and evaluate content validity. Thereafter, 371 participants completed the revised questionnaire and a debriefing form to allow preliminary psychometric analysis. Validity and reliability were assessed (correlation-based methods, Cronbach's α, and intra-class correlation coefficient). RESULTS: Eleven countries within and outside Europe enrolled patients. From the pretesting, 71 of the 80 original items fulfilled the criteria for item-retention. Most participants (80%) completed the revised 71-item questionnaire within 15 min, on paper (n = 175) or digitally (n = 196). The final questionnaire included 61 items that fulfilled criteria for item retention or were important to subgroups. Item-scale correlations were > 0.7 for all but nine items. Internal consistency (range 0.68-0.92) and test-retest results (all but one scale > 0.7) were acceptable. The instrument consists of 15 multi-item scales and six single items. CONCLUSION: The Oslo COVID-19 QLQ-W61© is an international, stand-alone, multidimensional HRQoL questionnaire that can assess the symptoms, functioning, and overall quality of life in COVID-19 patients. It is available for use in research and clinical practice. Further psychometric validation in larger patient samples will be performed.

RESUMO

Introduction: Hypertension is an important public health menace globally and in sub-Saharan Africa. The prevalence of hypertension is on the rise in low- and lower-middle-income countries (LMIC) such as Ghana. This rise led to the adoption of the May Measurement Month (MMM) initiative, a global blood pressure screening campaign. We aimed to create awareness and present the findings of the 2019 MMM screening campaign in the Ashanti region of Ghana. Methods: Ghana was 1 of 92 countries that participated in this global community-based cross-sectional study in May 2019. Participants (⩾18 years) were recruited by opportunistic sampling. The blood pressures of participants were measured 3 times and the mean of the last 2 was used for the analysis. Summary statistics were used to describe the data. Simple and multiple logistic regression models were used to determine the predictors of hypertension. Results: We screened 3080 participants with a mean age of 39.8 ± 16.8 years. The prevalence of hypertension was 27.3% among participants. Two-thirds of the hypertensives were unaware of their condition and only 49.5% of participants with a history of hypertension on medication were controlled. Predictors of hypertension in a multiple logistic regression were increasing age (OR = 1.05 (CI 1.04-1.06), P < .001) and high body mass index (OR = 1.06 (1.02-1.10), P = .005). Conclusion: The MMM initiative is highly commendable and of huge public health importance in LMICs like Ghana. Population-based health programs such as the MMM initiative is encouraged to shape appropriate public health policies to reduce the prevalence of hypertension.

RESUMO

Background Although sub-Saharan Africa has a high prevalence of cardiovascular diseases (CVDs), there remains a lack of systematic and comprehensive assessment of risk factors and early CVD outcomes in adults in sub-Saharan Africa. Methods and Results Using a stratified multistage random sampling method, we recruited 1106 men and women, aged >18 years, from the general population in Ghana to participate in a national health survey from 2016 to 2017. In Ghanaian adults, the age-standardized prevalence of known CVD risk factors was 15.1% (95% CI, 12.9%-17.3%) for obesity, 6.8% (95% CI, 5.1%-8.5%) for diabetes mellitus, 26.1% (95% CI, 22.9%-29.4%) for hypertension, and 9.3% (95% CI, 7.1%-11.5%) for hyperuricemia. In addition, 10.1% (95% CI, 7.0%-13.2%) of adults had peripheral artery disease, 8.3% (95% CI, 6.7%-10.0%) had carotid thickening, 4.1% (95% CI, 2.9%-5.2%) had left ventricular hypertrophy, and 2.5% (95% CI, 1.5%-3.4%) had chronic kidney disease. Three CVD risk factors appeared to play prominent roles in the development of target organ damage, including obesity for peripheral artery disease (odds ratio [OR], 2.22; 95% CI, 1.35-3.63), hypertension for carotid thickening (OR, 1.92; 95% CI, 1.22-3.08), and left ventricular hypertrophy (OR, 5.28; 95% CI, 2.55-12.11) and hyperuricemia for chronic kidney disease (OR, 5.49; 95% CI, 2.84-10.65). Conclusions This comprehensive health survey characterized the baseline conditions of a national cohort of adults while confirming the prevalence of CVD risk factors, and early CVD outcomes have reached epidemic proportions in Ghana. The distinct patterns of risk factors in the development of target organ damage present important challenges and opportunities for interventions to improve cardiometabolic health among adults in Ghana.

RESUMO

Background: Lipoprotein(a) [Lp(a)] and high-sensitivity C-reactive protein (hs-CRP) levels are associated with cardiovascular disease (CVD) in the general population, even after adjusting for conventional CVD risk factors. However, data are limited regarding the distribution of Lp(a) and hs-CRP among patients with HIV in Ghana. We explored levels of Lp(a), hs-CRP and other cardiovascular risk factors among people who were HIV positive (HIV+) on ART (HIV+ART+), HIV+ART-, and HIV-ART- in a Ghanaian population. Methods: We conducted a cross sectional study, recruited individuals who were HIV+ART+ and HIV+ART- from the largest HIV clinic in central Ghana between August 2018 and December 2019. HIV negative controls were recruited from communities and adjoining suburbs of Kumasi. Lipoprotein(a) was measured using Immunoturbidimetric assay and high sensitive-CRP concentrations were determined using particle-enhanced turbidimetric assay. We compared levels of Lp(a), hs-CRP, and conventional CVD risk factors among these groups and used multivariable stepwise logistic regression models to explore associations between them. Results: Among HIV+ART+ (n = 156), HIV+ART- (n = 131), and HIV-ART- (n = 147), mean(SD) ages were 48 (9.1) years, 41 (11.1) years and 45 (11.9) years, p = <0.001, proportion of females were 71.2%, 67.9% and 73.5% respectively. Median(IQR) concentrations of hs-CRP in mg/L were 1.7 (0.8,4.5), 2.03 (0.5,8.58) and 1.0 (0.45,2.74) across respective groups and the proportion of elevated Lp(a) concentrations (Lp[a] > 30mg/dL) were 70%, 48% and 62% among HIV+ART+,HIV+ART- and HIV-ART- participants respectively. Diabetes mellitus, dyslipidemia, waist-to-hip ratio and metabolic syndrome were associated with higher hs-CRP levels. Compared to HIV-ART-, HIV+ patients had higher odds of having hs-CRP > 3mg/L while HIV+ART+ patients had higher odds of elevated Lp(a) than HIV+ART- after multivariable adjustment. Conclusion: PLWHA in Ghana are associated with higher odds of elevated hs-CRP, regardless of ART use. HIV+ART+ is significantly associated with higher odds of elevated Lp(a) levels compared to HIV+ART-; even after multivariable adjustments. Reasons for this and potential clinical implications merit further study.

RESUMO

BACKGROUND AND AIMS: African populations have a favourable lipid profile compared to European populations. However, the extent to which they differ between rural and urban settings in Africa and upon migration to Europe is unknown. We assessed the lipid profiles of Ghanaians living in rural- and urban-Ghana and Ghanaian migrants living in three European countries. METHODS: We used data from a multi-centre, cross-sectional study among Ghanaian adults residing in rural- and urban-Ghana and London, Amsterdam and Berlin (n = 5482). Dyslipidaemias were defined using the 2012 European Guidelines on Cardiovascular Prevention. Comparisons between groups were made using age-standardised prevalence and prevalence ratios (PRs) with adjustments for important covariates. RESULTS: In both sexes, the age-standardised prevalence of high total cholesterol (TC) and LDL-cholesterol (LDL-C) was lower in rural- than in urban-Ghana and Ghanaian migrants in Europe. Adjusted PRs of high TC and LDL-C were higher in urban-Ghana (TC PR = 2.15, 95%confidence interval 1.69-2.73) and Ghanaian migrant men (TC PR = 2.03 (1.56-2.63)) compared to rural-Ghana, but there was no difference between rural- and Ghanaian migrant women (TC PR = 1.01 (0.84-1.22)). High triglycerides levels were as prevalent in rural-Ghana (11.6%) as in urban-Ghana (12.8%), but were less prevalent in Ghanaian migrant women (2.0%). In both sexes, low HDL-cholesterol was most prevalent in rural-Ghana (50.1%) and least prevalent in Europe (12.9%). CONCLUSION: The lipid profile varied among ethnically homogeneous African populations living in different geographical locations in Africa and Europe. Additional research is needed to identify factors driving these differential risks to assist prevention efforts.

RESUMO

Cardiovascular health (CVH) is a construct defined by the American Heart Association (AHA) as part of its 2020 Impact Goal definition. CVH has, until now, not been evaluated in Sub-Saharan African populations. The aim of this study was to investigate differences in the prevalence of ideal CVH and its constituent metrics among Ghanaians living in rural and urban Ghana and Ghanaian migrants living in three European countries. The AHA definition of CVH is based on 7 metrics: smoking, body mass index, diet, physical activity, blood pressure, total cholesterol, and fasting plasma glucose. These were evaluated among 3510 Ghanaian adults (aged 25-70 years) residing in rural and urban Ghana and three European cities (Amsterdam, London and Berlin) in the multi-centre RODAM study. Differences between groups were assessed using logistic regression with adjustments for gender, age, and education. Only 0.3% of all participants met all 7 metrics of the AHA's definition of ideal CVH. Compared to rural Ghana (25.7%), the proportions and adjusted odds ratio (OR) of individuals who had 6-7 CVH metrics in the ideal category were substantially lower in urban Ghana, (7.5%; OR 0.204, 95% CI 0.15-0.29), Amsterdam (4.4%; 0.13, 0.08-0.19), Berlin (2.7%; 0.06, 0.03-0.11), and London (1.7%; 0.04, 0.02-0.09), respectively. The proportion of ideal CVH for the various metrics ranged from 96% for all sites in the smoking metric to below 6% in the diet metric. The proportion of ideal CVH is extremely low in Ghanaians, especially among those living in urban Ghana and Ghanaian migrants in Europe.

RESUMO

BACKGROUND: HCV RNA screening of large sample repositories provides data on HCV epidemic patterns that may help guide control policies. In resource-limited settings, shipment of frozen samples to molecular laboratory facilities and testing of individual samples may be prohibitively expensive. OBJECTIVE: Our aim was to detect and sequence HCV RNA in a large HIV-positive cohort from Kumasi, Ghana, using pooled and individual dried plasma spots (DPS) produced from samples stored at -80°C. STUDY DESIGN: In the validation phase, replicate DPS were prepared with six dilutions (500-10,000 IU/ml) of the 4th International Standard for HCV and tested in three independent experiments. In the testing phase, DPS prepared with plasma samples from 875 HIV-positive subjects were pooled for screening, followed by testing of individual DPS of positive pools. Input from individual DPS was two 6mm punches; pools comprised two punches from each of five DPS. Genotypes were determined by Sanger sequencing of HCV core and NS5B. RESULTS: With the dilution series, sensitivity of HCV RNA detection was ≥2500 IU/ml. Replicate DPS gave intra-assay and inter-assay coefficients of variation ≤1.4%. With the stored samples, HCV RNA was detected in 5/175 DPS pools and in one DPS from each positive pool, yielding a HCV RNA prevalence of 5/875 (0.57%; 95% confidence interval 0.07-1.07%). The five samples were sequenced as HCV genotypes 2l and 2r. DISCUSSION: DPS allowed reproducible HCV RNA detection, and pooling effectively contained the cost and labour of screening a previously untested, low-prevalence cohort. DPS were also suitable for HCV sequencing.

RESUMO

BACKGROUND: Africa has a growing burden of stroke with associated high morbidity and a 3-year fatality rate of 84%. Cardiac disease contributes to stroke occurrence and outcomes, but the precise relationship of abnormalities as noted on a cheap and widely available test, the electrocardiogram (ECG), and acute stroke outcomes have not been previously characterized in Africans. OBJECTIVES: The study assessed the prevalence and prognoses of various ECG abnormalities among African acute stroke patients encountered in a multisite, cross-national epidemiologic study. METHODS: We included 890 patients from Nigeria and Ghana with acute stroke who had 12-lead ECG recording within first 24 h of admission and stroke classified based on brain computed tomography scan or magnetic resonance imaging. Stroke severity at baseline was assessed using the Stroke Levity Scale (SLS), whereas 1-month outcome was assessed using the modified Rankin Scale (mRS). RESULTS: Patients' mean age was 58.4 ± 13.4 years, 490 were men (55%) and 400 were women (45%), 65.5% had ischemic stroke, and 85.4% had at least 1 ECG abnormality. Women were significantly more likely to have atrial fibrillation, or left ventricular hypertrophy with or without strain pattern. Compared to ischemic stroke patients, hemorrhagic stroke patients were less likely to have atrial fibrillation (1.0% vs. 6.7%; p = 0.002), but more likely to have left ventricular hypertrophy (64.4% vs. 51.4%; p = 0.004). Odds of severe disability or death at 1 month were higher with severe stroke (AOR: 2.25; 95% confidence interval: 1.44 to 3.50), or atrial enlargement (AOR: 1.45; 95% confidence interval: 1.04 to 2.02). CONCLUSIONS: About 4 in 5 acute stroke patients in this African cohort had evidence of a baseline ECG abnormality, but presence of any atrial enlargement was the only independent ECG predictor of death or disability.

RESUMO

BACKGROUND: Antiretroviral treatment (ART) programs in sub-Saharan Africa have for many years included lamivudine as the sole hepatitis B virus (HBV) inhibitor. Long-term outcomes and the effects of introducing tenofovir as part of ART in these populations have not been characterized. METHODS: The study comprised a cross-sectional analysis of 106 human immunodeficiency virus (HIV)/HBV-coinfected subjects maintained on lamivudine, as well as a prospective analysis of 76 lamivudine-experienced subjects who introduced tenofovir. Patients underwent assessment of liver fibrosis by transient elastography (TE) and testing to characterize HIV type 1 (HIV-1) and HBV replication. RESULTS: After a median of 45 months of lamivudine treatment, HIV-1 RNA and HBV DNA were detectable in 35 of 106 (33.0%) and 54 of 106 (50.9%) subjects, respectively, with corresponding drug resistance rates of 17 of 106 (16.0%) and 31 of 106 (29.2%), respectively. Median TE values were 5.7 kPa (interquartile range, 4.7-7.2 kPa) and independently associated with HBV DNA load, aspartate aminotransferase levels, and platelet counts; 13 of 106 (12.3%) subjects had TE measurements >9.4 kPa. Twelve months after the first assessment, and a median of 7.8 months after introducing tenofovir, HBV DNA levels declined by a mean of 1.5 log10 IU/mL (P < .001). TE values changed by a mean of -0.2 kPa (P = .097), and declined significantly in subjects who had pretenofovir HBV DNA levels >2000 IU/mL (mean, -0.8 kPa; P = .048) or TE values >7.6 kPa (mean, -1.2 kPa; P = .021). HIV-1 RNA detection rates remained unchanged. CONCLUSIONS: A proportion of HIV/HBV-coinfected patients on long-term lamivudine-containing ART had poor HIV and HBV suppression, drug resistance, and TE values indicative of advanced liver fibrosis.

RESUMO

This study assessed the efficacy and acceptability of two rapid point-of-care HIV assays used in a voluntary counseling and testing (VCT) and a tuberculosis (TB) clinic in Kumasi, Ghana. Over a 4-week period in 2007, 95 individuals attending the VCT clinic and 35 patients with newly diagnosed TB were offered a rapid HIV test. Rates of return for positive results and attendance at the HIV clinic were compared with 471 individuals (395 attending the VCT clinic and 76 patients with TB), tested during an 8-week period 6 months earlier using standard testing procedures. All patients offered a rapid test in each clinic underwent testing, compared to 93% of VCT clients and 40% of TB patients offered a test 6 months earlier. In the rapid testing period, 37%, 60%, and 3% of the VCT clients and 26%, 74% and 0% of the TB patients had positive, negative, or indeterminate serology, respectively. There were no discordant results following retesting of patients with a positive test. All patients attending either the VCT or TB clinics who tested positive for HIV with the point-of-care test returned to the HIV clinic for care, while only 64% and 95%, respectively, of the patients previously testing positive had returned for follow-up. Both clients and staff showed high levels of satisfaction with the rapid testing procedure. In conclusion, rapid point-of-care testing in both of these settings was successful in improving diagnosis of HIV infection and engaging those testing positive in a clinical care program.
