RESUMO

BACKGROUND & AIMS: The objective is to ascertain the pattern of potential drug-drug interactions (pDDIs) and record any observed DDIs and adverse events (AEs) in hospitalized Beninese cardiology patients from Sub-Saharan Africa and analyze all risk factors associated with DDIs and AEs. METHODS: It was a prospective study in which data including AEs were assessed from medical files and interview of patients and their relatives. Patients who were treated with more than two drugs and who remained in the hospital for at least 48 hours were included. A computerized database system Pharma IAM- VIDAL version 2011 was used to identify the pattern for potential DDIs. RESULTS: 156 patients were included in this study. The prevalence of potential DDIs was estimated at 93 % (145/156). Forty (5.1%) among 804 potential DDIs identified were observed clinically. The observed DDIs were attributable to low blood pressure (27.5%), hyponatremia (22.5%), hemorrhage (20.0%), hyperkalemia (17.5%) and nephrotoxicity (7.5%). The combination of spironolactone and furosemide resulted in hyponatremia while the combination of enoxaparin and potassium resulted in hyperkalemia. ACE inhibitor (or ARAII) in combination with furosemide resulted in the nephrotoxicity cases observed. Enoxaparin, Acetyl salicylic acid, Acenocoumarol and Clopidogrel were decreasingly involved in the pairs of drugs responsible for observed hemorrhages. 29 patients out of 156 (18.6%) had at least one AE. AEs were mainly (34.2%) of metabolic type. Severe AEs, which represented 18.4% was mostly from nephrotoxicity and metabolic disorders. More than 14 active substances multiplied the risk factor for AEs occurrence by 42, while more than 14 days hospitalization increased this risk by 42. CONCLUSION: This study highlights the need to optimize treatments by strictly regulating blood pressure, serum sodium and potassium levels, coagulation parameters and looking for clinical signs of hemorrhage. Physician should be aware of certain drug associations that may carry a risk of severe adverse events.

RESUMO

Introduction : Au Bénin, en 2008, la prévalence de l'HTA dans le département du Mono au Sud-Ouest, était l'une des plus élevée avec 35,76%. L'objectif cette étude était d'évaluer les connaissances, les attitudes et les pratiques des patients sur l'HTA en vue d'adapter les messages de prévention en direction des populations. Méthode : Etude transversale descriptive avec collecte prospective des données, qui s'est déroulée dans l'arrondissement d'Akodéha du 20 Juillet au 20 Août 2016. Les patients âgés d'au moins 18 ans présents dans le centre de santé, ont été enquêtés de même que ceux qui y ont consulté au cours des 6 mois précédents l'enquête. Les connaissances globales sur l'HTA, les attitudes et les pratiques des enquêtés ont été collectées lors d'un entretien dirigé. Cinq items sont retenus pour l'évaluation : origine/ causes, symptômes, complications, dépistage, durée de traitement. Résultats : Nous avons enquêté 265 patients. La moyenne d'âge était 36,67±10,44 ans et le sex-ratio de 1,03 (M/F : 135/130). Parmi les enquêtés, 46,40% déclaraient savoir lire ou écrire dans une langue quelconque et parmi eux 82,0% ,avaient le niveau primaire ou secondaire et 17,35% le niveau universitaire. Seuls 22,73% des enquêtés ontdéclaré avoir une connaissance sur l'HTA. Les sources d'information sur l'HTA étaient : l'agent de santé (50%), les mass médias (22,05%), les lectures personnelles (17,65%), les tiers (10,29%). Sur les 5 items d'évaluation du niveau de connaissance globale, 96,7% des enquêtés qui déclaraient avoir une connaissance sur l'HTA, avaient des réponses bonnes, côtées au moins à 3/5. Seuls 23,85% des enquêtés déclaraient faire une activité physique régulière. Les repas riches en gras sont préférés par 45,11% et les repas hypersodés par 23,28% des enquêtés. Parmi les enquêtés hypertendus, 44,83% ne suivaient aucun régime et 74,07% ne suivaient aucun traitement médical. Conclusion : Cette étude montre un faible niveau de connais-sance sur l'HTA chez les patients du centre de santé d'Akodéha. Les attitudes et les pratiques ne sont pas favorables pour le contrôle de l'HTA. Les activités de prévention pour un changement de comportement doivent être menées lors du contact médical afin d'améliorer le niveau de connaissance des patients

RESUMO

OBJECTIVE: Hypertension results in more deaths than any other risk factor and has been on the rise in sub-Saharan Africa over the past few decades. Generic drugs have helped improve accessibility and affordability of antihypertensive therapy in developing countries. However, assessment of quality standards of these products is important. We performed a quality assessment of five commonly used antihypertensive generic drugs in 10 sub-Saharan African countries and studied the impact of price on quality. METHODS: Drug samples were prospectively collected using standardized methods between 2012 and 2014. We developed a validated reversed-phase liquid chromatography with tandem mass spectrometry method to accurately quantify the active ingredient in a certified public laboratory. Quality was defined based on the percentage ratio of measured to expected dosage of active ingredient. RESULTS: A total of 1185 samples were assessed, of which 70.0% were generic (n = 830). Among the generic drugs, the percentage of poor-quality drugs was 24.3% (n = 202/830). The percentage ratio of measured to expected dosage of active ingredient ranged from 49.2 to 111.3%; the majority (81.7%) of the poor-quality samples had insufficient quantity of the active ingredient. Moreover, poor quality was not associated with purchase price of the drug. CONCLUSION: In this study from 10 sub-Saharan African countries, nearly one-quarter of the available generic antihypertensive drugs were found to be of poor quality. Concerted measures to improve the quality of antihypertensive drugs could lead to major improvements in hypertension control with attendant reduction of its deleterious consequences in low-income and middle-income countries.

RESUMO

Double-chambered right ventricle (DCRV) is a very rare cardiac defect in which the right ventricle is divided by anomalous muscle bundle into two chambers. It is associated with other malformations in 80-90% of cases. Clinical presentation varies and depends on the extent of the intraventricular obstruction. We here report the case of a 16-year old teenager with isolated DCRV revealed by recurrent syncopes. The diagnosis was made using Doppler echocardiography. The patient underwent successful surgical resection of the abnormal muscle band.

RESUMO

BACKGROUND: The growing menace of poor quality and falsified drugs constitutes a major hazard, compromising healthcare and patient outcomes. Efforts to assess drug standards worldwide have almost exclusively focused on anti-microbial drugs; with no study to date on cardiovascular drugs. Our study aims to assess quality of seven routinely used cardiovascular medications (anticoagulants, antihypertensives and statins) in ten Sub-Saharan African countries. METHODS: Drugs were prospectively collected using standardized methods between 2012 and 2014 from licensed (random pharmacies) and unlicensed (street-markets) places of sale in Africa. We developed a validated reversed-phase liquid chromatography with tandem mass spectrometry method to accurately quantify the active ingredient in a certified public laboratory. Three quality categories were defined based on the ratio of the measured to the expected dosage of the active ingredient: A (good quality): 95% to 105%, B (low quality): 85 to 94.99% or 105.01 to 115%, C (very low quality): <85% or >115%. RESULTS: All expected medicines (n=3468 samples) were collected in Benin, Burkina-Faso, Congo-Brazzaville, the Democratic Republic of Congo, Guinea, Côte d'Ivoire, Mauritania, Niger, Togo and Senegal. Out of the 1530 samples randomly tested, poor quality (types B and C) was identified in 249 (16.3%) samples. The prevalence of poor quality was significantly increased in certain specific drugs (amlodipine 29% and captopril 26%), in generic versions (23%) and in drugs produced in Asia (35%). The proportion of poor quality reached 50% when drugs produced in Asia were sold in street-markets. CONCLUSION: In this first study assessing the quality of cardiovascular drugs in Africa, we found a significant proportion of poor quality drugs. This requires continued monitoring strategies.

RESUMO

AIM: The aim of this retrospective study was to evaluate the use and appropriateness of preventive measures for venous thrombosis among adult inpatients in a Benin teaching hospital. PATIENTS AND METHODS: All patients were systematically enrolled. The risk of venous thrombosis was estimated according to international guidelines. Thromboembolic events were diagnosed using the Wells score and, when possible, by paraclinical investigations. The following variables were studied: the risk of venous thrombosis, the use and appropriateness of preventive measures, and the frequency of thromboembolic events. The data were analyzed with Epiinfo 6.04.fr and SPSS software, and significance was assumed at p=0.05. RESULTS: The study population consisted of 487 patients recruited in four surgical wards, four general wards and one obstetric-gynecology ward. Mean age was 38.7+/-11.3 years and the sex ratio 0.51. The risk of thrombosis was considered low in 15% of patients, moderate in 60.8%, high in 21.1% and very high in 3.1%. Prophylactic measures were prescribed to 33.9% of the patients overall, 53.6% in the obstetric gynecology ward, 28.5% in the surgical wards and 12.9% in the general wards. The frequency of preventive measures rose with the level of risk (p<0.0001). Preventive measures consisted of passive mobilization, aspirin, enoxaparin and acenocoumarol. The prescriptions were appropriate in only 6% of cases. Among 198 patients who were monitored for two months after hospital discharge, 8% had a venous thromboembolic event. Such events were more frequent in the absence of prophylaxis (12% vs 3.3%, p=0.02). CONCLUSION: The risk of venous thromboembolic is recognized but poorly managed in this Bénin teaching hospital.
