RESUMEN

Antiretroviral therapy (ART) has extended the lifespan of people living with HIV/AIDS (PLHIV), exposing them to a higher risk of cardiovascular diseases (CVD). Hypertension (HTN), the primary contributor to CVD burden, is increasingly concerning for PLHIV. This study aimed to assess the prevalence and associated factors of hypertension in PLHIV on ART at the National Teaching Hospital Hubert Koutoukou Maga (HKM) of Benin using a prospective cross-sectional study conducted between October and December 2021. Patients who had a systolic blood pressure ≥ 140 mmHg or/and diastolic blood pressure ≥ 90 mmHg or/and current use of antihypertensive medication from medical records were considered to have HTN. A total of 352 patients, including 260 women with a sex ratio of 0.3 were included. The mean age was 42.9 ± 11.9 years. Most patients were educated and did not use tobacco. 42.0% were current alcohol drinkers. The duration of ART treatment ranged from 0 to 22 years, with a median duration of 5.0 years. 14.2% were hypertensives with 3.1% newly diagnosed and 11.1% known with hypertension. Age above 40 years, living with a partner, alcohol consumption and body mass index greater than 25 were significantly associated with HTN. HTN in PLHIV is associated with numerous factors. Reducing the burden of the disease in target people in Benin requires a wide range of actions that need to be implemented.

RESUMEN

BACKGROUND: In Benin, a country in West Africa, breast cancer is the leading cancer in women, both in terms of incidence and mortality. However, evidence on the mortality of breast cancer and its associated factors is lacking in this country. Our aim was to describe and analyze the clinical, histopathological, and prognostic aspects of breast cancer in Benin. METHODS: A descriptive and analytical study was carried out at the CNHU-HKM and the CHU-MEL, two major tertiary referral hospitals for breast cancer management located in Cotonou, the capital city of Benin. All breast cancer medical records with histological evidence and immunohistochemistry studies were retrospectively collected between January 1, 2014, and September 30, 2020, in these two tertiary referral hospitals and analyzed in the current study. RESULTS: Finally, 319 medical records were included. The mean age at diagnosis was 48.74 years. The tumors were most frequently classified as T4 (47.6%) with lymph node involvement N2 (34.5%), and metastases were clinically noted in 21.9% of cases. Stage was reported in the medical records of 284 patients. Tumors were diagnosed at very late AJCC stages: stage III (47.5%) and stage IV (24.7%). Grades SBR 2 (49.2%) and SBR 3 (32.6%) were the most frequent grades. Triple-negative breast cancer (31.3%) was the most common molecular type. The overall 5-year survival was 48.49%. In multivariable analysis, the poor prognostic factors were lymph node invasion (HR = 2.63; p = 0.026; CI: [1.12, 6.17]), the presence of metastasis (HR = 3.64; p < 0.001); CI: [2.36, 5.62] and the immunohistochemical profile (HR = 1.29; p < 0.001; CI: [1.13, 1.48]). CONCLUSIONS: Breast cancer in Beninese is predominant in young adults and is often diagnosed at a late stage. The survival of breast cancer patients in Benin can be improved by enhancing early diagnosis and multidisciplinary management.

RESUMEN

OBJECTIVE: To determine the association between occupational factors, particularly psychosocial factors, and hypertension. DESIGN: Descriptive and analytical cross-sectional study using logistic multivariate regression. SETTING: Fifteen cotton ginning plants in Benin. PARTICIPANTS: Permanent and occasional workers in the cotton ginning industry. DATA COLLECTION: Data on sociodemographic, occupational, behavioural and clinical history characteristics were collected using a number of standardised, interviewer-administered questionnaires. These questionnaires were based on the WHO's non-communicable disease questionnaire, Karasek questionnaire and Siegrist questionnaire. Weight, height and blood pressure were measured. Any worker with systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg according to the WHO criteria was considered hypertensive, as was any subject on antihypertensive treatment even if blood pressure was normal. RESULTS: A total of 1883 workers were included, with a male to female ratio of 9.08. Of these, 510 suffered from hypertension (27.1%, 95% CI 25.1 to 29.2). In the multivariate analysis, the risk factors identified were occupational stress (adjusted OR (aOR)=3.96, 95% CI 1.28 to 12.2), age ≥25 years (aOR=2.77, 95% CI 1.55 to 4.96), body mass index of 25-30 kg/m2 (aOR=1.71, 95% CI 1.32 to 2.2), body mass index >30 kg/m2 (aOR=2.74, 95% CI 1.84 to 4.09), permanent worker status (aOR=1.66, 95% CI 1.44 to 2.41) and seniority in the textile sector >5 years (aOR=2.18, 95% CI 1.7 to 2.8). Recognition at work emerged as an effect-modifying factor subject to stratification. CONCLUSIONS: Occupational factors, particularly job strain and recognition at work, are modifiable factors associated with hypertension in the ginning plants sector and deserve to be corrected through occupational health promotion and prevention.

RESUMEN

BACKGROUND: Dementia is a growing global health challenge, with significant socioeconomic implications. This study examined the informal care duration and related costs along with the total cost of care for older individuals with dementia in Benin, West Africa, providing insights into a region with limited dementia research. METHODS: We conducted a cost-of-illness study in Benin. Both hospital and community recruitments were used to enroll adults aged ≥60 years and their primary caregivers. Structured questionnaire and validated tools were used to collect the demographic, clinical, healthcare resource utilization data as well as informal care duration. Replacement costs approach was performed to valuate informal care time. Official exchange rates from the World Bank were used to convert costs from local currency to purchasing power parities dollars (PPP$). RESULTS: Data from 135 individuals with varying dementia stages revealed that dementia places substantial caregiving demands, predominantly on women who provide up to 8 h of daily care. In 2021, the mean annual cost of dementia care was estimated to be PPP$ 2,399.66 ± 2,057.07. Informal care represented a significant portion of dementia expenses, up to 92% of the total care costs in this study. DISCUSSION: Policy interventions are urgently needed to address the dementia care challenges in Benin, especially because economic transitions and educational advancements may reduce the availability of informal caregivers. This emphasizes the vital role of informal caregivers and underscores the need of implementing dementia policies to support families facing the evolving challenges of dementia care.

RESUMEN

OBJECTIVES: We investigated the association between urban/rural location and both type 2 diabetes mellitus (T2DM) and pre-diabetes among populations of five West African countries. DESIGN: Cross-sectional studies, using the WHO Stepwise (STEPs) survey data. SETTING: National representative data of both urban and rural areas from Benin, Burkina Faso, Ghana, Liberia and Mali. PARTICIPANTS: Adults comprising 15 468 participants (6774 men and 8746 women; 7663 urban and 7805 rural residents) aged between 25 and 64 years. RESULTS: The age and sex-adjusted prevalence of T2DM was 6.2% for urban areas and 2.5% for rural areas. The prevalence of impaired fasting glucose (IFG) was 6.6% for urban areas, and 3.0% for rural areas. No differences by sex were observed. The crude relative risk (RR) and 95% CI of T2DM and IFG in urban compared with rural areas were 2.69 (1.85 to 3.91) and 2.37 (1.53 to 3.66), respectively. This reduced to RR: 2.03, 95% CI (1.34 to 3.08) and RR: 2.04, 95% CI (1.27 to 3.28), respectively, after adjusting for covariables. CONCLUSION: The prevalence of both T2DM and IFG was more than two times as high in urban areas compared with rural areas in West Africa. Behavioural risk factors are common among urban populations, with ongoing urbanisation expected to drive increases in the prevalence of T2DM. These results could guide planning for T2DM screening, preventive strategies and resource allocation in West Africa.

RESUMEN

AIMS: To determine normal limits for major ECG variables, and the electrocardiographic impact of hypertension, in a rural sub-Saharan African setting. METHODS: This cross-sectional study included adults aged ≥25 years from Tanvè Health Study (TAHES) cohort. ECG were recorded at rest at 25 mm/s using a standard 12­lead device. Wave amplitudes and durations were measured. Corrected QT interval (QTc) was calculated using Bazett's formula. Sokolow-Lyon, Cornell and Peguero-Lo Presti criteria were determined to assess left ventricular hypertrophy (LVH). RESULTS: ECG was recorded among 997 out of 1407 TAHES participants. After exclusion of subjects with hypertension or diabetes, normal limits, defined as the 2nd and 98th percentiles, were evaluated in 622 healthy participants (median: 37 years; 60.1% women). The following limits were established in men (women): heart rate: 50 to 100 (55 to 102) beats/min, P wave duration: 80 to 120 (80 to 120) ms, PR interval: 120 to 200 (120 to 200) ms, QTc: 315 to 470 (323 to 465) ms, QRS duration: 50 to 120 (50 to 110) ms. Upper limits (in millimeter) for the Sokolow-Lyon, Cornell and Peguero-Lo Presti for men (women) were 47 (38), 30 (22) and 39 (30), respectively, all above current reference limits. The prevalence of LVH in hypertensive subjects according to these criteria were lower than those estimated according to current LVH criteria. CONCLUSION: The normal limits of ECG variables determined in this African population differ from those in Caucasians, indicating that ethnicity must be considered in ECG interpretation.

RESUMEN

Introduction: Breast cancer requires multidisciplinary management. Pathologists and physicians communicate using the histopathology request form and the pathology report. There are some minimal criteria that both should respect. Objective: We assessed the adequacy of histopathology request forms and pathology reports in the management of female breast cancer specimens in Southern Benin. Method: This was a cross-sectional, descriptive and analytical study, with retrospective data collection over 57 months (4 years and 9 months). The adequacy of the histopathology request forms and pathology reports was assessed on the basis of the recommendations of the Haute Autorité de Santé (HAS) of France. Data processing was done using SPSS software. We checked frequencies with the Chi2 test, with a significance level set at 5%. Results: 31.3% of histopathology request forms complied with HAS recommendations. Pathology reports were presented in a narrative way in 92.7% of cases and 68.8% met the minimal criteria. The presence of vascular embolus, of hormone receptors and the HER2 status were all reported in only 29.2% of the reports. Discussion: The draft of histopathology request forms and pathology reports did not comply to the required minimal criteria. This situation could mainly be explained by the inexistence of consensus between physicians and pathologists and by the lack of immunohistochemistry. Editing national referentials and using synoptic reports would give better results.

RESUMEN

OBJECTIVES: Inter-arm blood pressure difference (IABPD) can lead to underdiagnosis and poor management of hypertension, when not recognized and are associated with increased cardiovascular mortality and morbidity. However, the prevalence and associated risk factors of IABPD in sub-Saharan Africa are unknown. This study aims to determine the prevalence and associated risk factors of IABPD among Tanve Health Study (TAHES) participants, a cohort about cardiovascular diseases in a rural area in Benin. METHODS: The cohort was conducted since 2015 among adults aged 25 years and over in Tanve village. Data were collected from February to March, 2020. Brachial blood pressure were recorded at rest on both arm with an electronic device. Systolic IABPD (sIABPD) was defined as the absolute value of the difference in systolic blood pressure between left and right arms ≥ 10 mmHg. A multivariate logistic regression models identified factors associated with sIABPD. RESULTS: A total of 1,505 participants (women 59%) were included. The mean age was 45.08 ±15.65 years. The prevalence of sIABPD ≥ 10 mmHg was 19% (95%CI: 17-21). It was 19% (95%CI: 16-22) in men and 20% (95%CI: 17-22) in women. In final multivariable model, the probability of sIABPD ≥ 10 mmHg increased significantly with age (adjusted OR (aOR) = 1.1; 95%CI: 1.02-1.20 per 10-years), hypertension (aOR = 2.33; 95%CI: 1.77-3.07) and diabetes (aOR = 1.96; 95%CI: 1.09-3.53). CONCLUSION: Almost quarter of sample have a sIABPD ≥ 10 mmHg, with an increased risk with older age and hypertension and diabetes.

RESUMEN

BACKGROUND: Maternal mortality is a public health issue, particularly in low- and middle-income countries (LMIC). Sub-Saharan Africa (SSA) is the region most affected worldwide by maternal mortality, and preeclampsia is one of the main causes. We performed a systematic review of observational studies to identify the impact of cardiovascular risk factors on preeclampsia in SSA with a more representative sample. METHODS: Databases: PubMed and Google Scholar were searched to identify published studies. Studies were included if they reported results on the link between at least one cardiovascular risk factor and preeclampsia. Relevant studies quality was assessed with the Newcastle-Ottawa Scale (NOS). Odds ratios and relative risk (RR) were reported with their confidence intervals. RESULTS: Twelve articles (8 case-controls, 3 cohorts, 1 cross-sectional) were included in this review, with a total of 24,369 pregnant women. Cardiovascular risk factors such as chronic hypertension, overweight, obesity, diabetes and alcohol were significantly associated with a high risk of preeclampsia. Very few data were available concerning some risk factors. None of the articles reported tobacco consumption as a preeclampsia risk factor. There is a lack of data from French-speaking SSA countries. CONCLUSION: Cardiovascular risk factors increase the risk of preeclampsia. Our results suggest the need for prospective cohort studies to ascertain this association in order to reduce maternal mortality due to preeclampsia.

RESUMEN

INTRODUCTION: the aim of this work is to evaluate the contribution of thoracic computed tomography (CT) in the diagnosis of COVID-19 in Guinea. METHODS: this was a retrospective study with data recorded over a 2 Month period. Records of patients who tested positive on chest CT without contrast injection on admission were included in this study. Not included are those who did or did not perform a chest CT scan after confirmation of the diagnosis by RT-PCR. The data were collected under the direction of the National Health Security Agency (ANSS) and analysed using STATA/SE version 11.2 software. RESULTS: all patients tested performed a chest CT scan without contrast injection while awaiting the RT-PCR test result. Eighty percent (80%) of patients had lesions characteristic of COVID-19 viral pneumonia on chest CT. The reverse transcriptase PCR (RT-PCR) test was later positive in 33 patients (94.28%) and negative in 2 (5.71%). CONCLUSION: it is noted from this study that chest computed tomography is a critical tool in the rapid diagnosis of COVID-19 infection. Its systematization in all patients suspected in our dispute, would facilitate diagnosis while waiting for confirmation by RT-PCR and would limit the loss of cases.

RESUMEN

The new coronavirus 2019 epidemic declared in China on December 31, 2019 soon spread to the rest of the world, becoming the subject of an unprecedented health pandemic according to the World Health Organization's declaration of March 11, 2020. It is a disease that has the potential to cause multiple systemic infections. We report here the case of an acute polyradiculoneuritis of the Guillain-Barré type (GBS) indicative of a COVID-19 infection. This is a 41 year old patient seen for ascending, symmetrical and bilateral, progressive and acute tetraparesis with in a context of influenza syndrome and digestive infections treated 2 weeks earlier. During a COVID-19 infection, certain inflammatory cells stimulated by the virus produce inflammatory cytokines creating immune-mediated processes. The same mechanism is observed in GBS being also an immune-mediated disorder. The management of this disease in COVID-19 positive patients does not differ from that of patients who do not carry the virus. The risk of respiratory distress in COVID-19 positive patients becomes twice as great in patients with GBS who test positive for COVID-19 at the same time. Monitoring for hemodynamic disorders and respiratory distress in a neuro-intensive care unit may be fruitful.

RESUMEN

The coronavirus 19 (COVID-19) disease, which was declared in China in December 2019, very early on became a pandemic, claiming more than 28 million victims worldwide to date. Its impact on the central nervous system is still poorly understood. The objective of this work is to assess the involvement of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in the aggravation of seizures in children known to have epilepsy and in the epileptogenesis of children hitherto seizure-free. Prior to conducting this work, we had obtained informed consent from patients and parents. We report the cases of three (3) patients, one known epileptic and the other two apparently healthy, who presented a febrile seizure in a context of COVID-19 infection. The aggravation of the epileptic seizure was indicative of a SARS-CoV-2 infection in the first patient, while the seizure occurred after induction of chloroquine sulfate treatment in the 2 other patients. Although our current concern is to limit the spread of the disease to COVID-19, it is crucial to address its possible complications. Notably, the worsening of seizures in children with epilepsy and the occurrence of first seizures in children without epilepsy following drug treatment. Equipping our COVID-19 patient management facilities with electroencephalogram (EEG) equipment could facilitate continuous electroencephalographic monitoring of children for proper management.

RESUMEN

The aim of this study was to evaluate the main clinical and evolutionary features of SARS-CoV-2 infection in children aged 0-18 years who were suspected and diagnosed for COVID-19 during routine consultations in the pediatric ward of the Ignace Deen National Hospital in Conakry. This retrospective study targeted all children admitted to the Pediatrics Department during the study period and focused on children whose clinical examination and/or history indicated a suspicion of SARS-CoV-2 infection. Only children with a positive reverse transcriptase-polymerase chain reaction (RT-PCR) test were included. Clinical and paraclinical data were rigorously analyzed. Anonymity and respect for ethical rules were the norm. Medical records were used as the data source and a questionnaire was developed for collection. The analysis was done using STATA/SE version 11.2 software. The mean age of the patients observed was 9.66±1.32 years, with a sex ratio of 1.25. The history of the patients found that 36.11 had already been in contact with a COVID-19 positive subject, of which 8 or 22 had close relatives treated for COVID-19 and 5 had been with classmates treated for COVID-19. Fever and physical asthenia, runny nose and throat pain were respectively found in 58.33%, 50% and 30.55% of patients with irritability in 25%. Asymptomatic children were 30.55%. The diagnosis was confirmed after a positive RT-PCR test. Thoracic computed tomography (CT) scan was normal in 80.55% of the children. They were given mostly azithromycin 15mg/kg, zinc and chloroquine sulfate 5mg/kg. The mean age of the patients observed was 9.66 years, with a sex ratio of 1.25.

RESUMEN

INTRODUCTION: The prevalence of hepatitis B is very variable across geographic areas and seems to be influenced by HIV infection. This study aims to evaluate the impact of serologic HIV status on the overall prevalence of hepatitis B in a Hospital in Parakou, Benin. METHODS: We conducted a cross-sectional study of adults aged 18 years old and over hospitalized in the Departmental University Hospital Center in Parakou between May 2011 and June 2012. The diagnosis of hepatitis B was made on the basis of rapid HBsAg tests while the diagnosis of HIV was made on the basis of rapid HIV tests using venous blood samples. Data were analyzed using EpiInfo software. Multivariate logistic regression model was implemented to investigate factors associated with hepatitis B. RESULTS: Out of 1516 subjects included, 744 were HIV seropositive. The average age was 31.3 + 11.1 years and 65.1% were women. The prevalence rate of hepatitis B in the whole sample was 13.9% [CI95:12.2%-15.7%]. This prevalence was higher in HIV seropositive subjects (16.9% vs 10.9%; p < 0.0006), however there was not a more significant difference in multivariate analysis, except for the group of subjects from Borgou/Alibori (p < 0.02). A consistent association was observed between age group 24-44 years (p < 0.03), male sex (p < 0.01), primary school education (p < 0.02) and a high prevalence of hepatitis B. CONCLUSION: The prevalence of hepatitis B was higher in HIV seropositive subjects. This was influenced by age, sex, education level and geographical origin.

RESUMEN

OBJECTIVE: To describe and compare the prevalences of CVRF in urban and rural populations of Benin. METHODS: Subjects were drawn from participants in the Benin Steps survey, a nationwide cross-sectional study conducted in 2008 using the World Health Organisation (WHO) stepwise approach to surveillance of chronic disease risk factors. Subjects aged above 24 and below 65 years were recruited using a five-stage random sampling process within households. Sociodemographic data, behavioral data along with medical history of high blood pressure and diabetes mellitus were collected in Step 1. Anthropometric parameters and blood pressure were measured in Step 2. Blood glucose and cholesterol levels were measured in Step 3. CVRF were defined according to WHO criteria. The prevalences of CVRF were assessed and the relationships between each CVRF and the area of residence (urban or rural), were evaluated using multivariable logistic regression models. RESULTS: Of the 6762 subjects included in the study, 2271 were from urban areas and 4491 were from rural areas. High blood pressure was more prevalent in urban than in rural areas, 29.9% (95% confidence intervals (95% CI): 27.4, 32.5) and 27.5% (95% CI: 25.6, 29.5) respectively, p = 0.001 (p-value after adjustment for age and gender). Obesity was more prevalent in urban than in rural areas, 16.4% (95% CI: 14.4, 18.4) and 5.9% (95% CI: 5.1, 6.7), p<0.001. Diabetes was more prevalent in urban than in rural areas, 3.3% (95% CI: 2.1, 4.5) and 1.8% (95% CI: 1.2, 2.4), p = 0.004. Conversely, daily tobacco smoking was more prevalent in rural than in urban areas, 9.3% (95% CI: 8.1, 10.4) and 4.3% (95% CI: 3.1, 5.6), p<0.001. No differences in raised blood cholesterol were noted between the two groups. CONCLUSION: According to our data, CVRF are prevalent among adults in Benin, and variations between rural and urban populations are significant. It may be useful to take account of the heterogeneity in the prevalence of CVRF when planning and implementing preventive interventions.

RESUMEN

Introduction La migraine est une affection frequente ayant un important retentissement sur la vie socioprofessionnelle des migraineux. L'objectif de ce travail etait de determiner la prevalence de la migraine dans une population de travailleurs de la ville de Cotonou Cadre et methode Il s'agit d'une etude transversale prospective realisee dans 5 milieux de travail de la ville de Cotonou. Elle a ete menee selon une technique de sondage aleatoire systematique a 3 degres et porte sur 938 travailleurs. Le diagnostic de la migraine etait base sur les criteres IHS de 1988 avec une modification sur la duree ou le nombre des acces (IHS + probable). Resultats La prevalence des cephalees etait de 24;8(IC95: [22;1-27;8]). La prevalence de la migraine etait de 8;9(IC95: [7;2-10;9]) celle de la migraine IHS etant de 2;3; celle de la migraine probable de 6;6. Elle est significativement plus frequente chez les femmes 20;8(p10-7) et chez les cadres superieurs 16;9(p10-5). La migraine sans aura etait la forme la plus frequente (60;7). Conclusion Ces resultats suggerent une frequence de la migraine chez les travailleurs de la ville de Cotonou et imposent d'en etudier l'impact
