ABSTRACT

Décrire les aspects épidémio-cliniques des manifestations thrombotiques au cours de la COVID-19 au sein des hôpitaux militaires de Libreville et Akanda, Gabon. Méthodes : Nous avons mené une étude rétrospective et descriptive multicentrique d'une durée de 7 mois, du 01er septembre 2021 au 31 mars 2022, portant sur les patients admis dans les unités de réanimation des hôpitaux d'instruction des armées de Libreville (HIAOBO) et d'Akanda (HIAA), pour COVID-19 documentée ou suspectée. Résultats : Durant la période d'étude, 167 patients ont été́ admis pour infection à SARS-CoV-2, parmi lesquels, 18 ont présentés des manifestations thromboemboliques (10,8%). La moyenne d'âge était de 54,7±6.4 ans. Il y avait une large prédominance masculine avec un sexe ratio à 2. Nous avons noté́ 9 cas d'embolie pulmonaire (50%), 5 cas d'accidents vasculaires cérébraux ischémiques (28%), 1 cas de thrombose veineuse profonde de membre inferieur (6%), 1 cas de thrombose veineuse cérébrale (6%), 1 cas de thrombose de la veine mésentérique (6%) et 1 cas de thrombose de la veine porte (6%). Les D-dimères étaient élevés chez tous les patients. Les globules blancs étaient élevés (>10000/mm3 ) chez 12 patients (67%). Les plaquettes étaient inférieures à 150000/mm3 pour 6 patients (33%). Tous les patients avaient une pneumonie à SARS-CoV-2 et la moyenne d'atteinte deslésions pulmonaires était estimée à 45%. Neuf patients étaient décédés (50%) au cours de l'hospitalisation. Conclusion : L'infection par le SARS-CoV-2 constitue vraisemblablement une prédisposition à la survenue d'un événement thrombotique. L'incidence des manifestations thrombotiques chez les patients atteints de COVID-19 reste élevée, renforçant ainsi la prescription systématique d'une anticoagulation prophylactique

ABSTRACT

La COVID-19 est associée à un état d'hypercoagulabilité. L'incidence du thrombus intraventriculaire gauche est relativement faible en absence d'une cardiopathie hypokinétique sévère avec altération de la fraction d'éjection. Nous rapportant le cas d'un homme de 37 ans infecté par le SARS-CoV-2 présentant un thrombus intraventriculaire gauche en absence de cardiopathie connue. Le décès était survenu suiteà un arrêt cardiaque.

ABSTRACT

Background. An increased incidence of thromboembolic events in hospitalised COVID­19 patients has been demonstrated despite the use of low-molecular-weight heparin (LMWH). Antiplatelet therapy prior to admission and early in the disease course has been hypothesised to be protective against thrombosis.Objectives. To describe the bleeding and thrombosis outcomes in hospitalised patients with confirmed COVID­19 receiving LMWH, with and without concomitant antiplatelet therapy. Secondary objectives were to explore predictors of bleeding and thrombosis outcomes, and dosing practices of antiplatelet therapy and LMWH.Methods. We conducted a descriptive, cross-sectional study of bleeding and thrombosis outcomes at Tygerberg Academic Hospital, Cape Town, South Africa, during the first COVID­19 wave, in 808 hospitalised patients with confirmed COVID­19 receiving LMWH with and without concomitant antiplatelet therapy. Multivariate logistic regression analysis was performed if predictors were deemed statistically and clinically significant.Results. Patients receiving both LMWH and antiplatelet therapy had similar bleeding outcomes compared with patients only receiving LMWH (odds ratio (OR) 1.5; 95% confidence interval (CI) 0.6 - 4.0). Patients receiving both LMWH and antiplatelet therapy had increased odds of developing thrombosis compared with patients only receiving LMWH (OR 4.8; 95% CI 2.1 - 10.7).Conclusion. The bleeding risk in COVID­19 patients receiving both LMWH and antiplatelet therapy was not significantly increased. A potentially higher risk of thrombosis in patients receiving LMWH and antiplatelet therapy was observed. However, this could reflect confounding by indication. Randomised studies are required to further evaluate the use of antiplatelet therapy to treat hospitalised patients with COVID­19.

ABSTRACT

L'expansion planétaire du covid19 représente une crise sans précèdent ; cette pandémie a fait plus d'un million de mort en une année. En plus de l'atteinte pulmonaire, le virus a des implications majeures sur le système cardiovasculaire : les maladies cardiovasculaires pré existantes représentent un facteur de risque d'infection sévère avec augmentation de la mortalité, d'autre part l'infection entraine des complications cardiovasculaires qui aggravent le pronostic. Le lien entre le Covid19 et le système cardiovasculaire découle principalement de la voie d'entrée cellulaire du virus qui est assurée par sa liaison à une protéine membranaire l'enzyme de conversion de l'angiotensine (ECA), qui joue un rôle clé dans la régulation neurohumorale ; cette protéine est très présente au niveau du cœur et du poumon, d'où le tropisme du virus qui entraine la dysrégulation de cette voie cellulaire avec des répercussion sur la fonction cardiaque et respiratoire. Une polémique a déferlé concernant les traitements anti hypertenseurs et notamment les inhibiteurs du système rénine angiotensine aldostérone mais après évaluation des données actuelles, il est de consensus de ne pas arrêter ou changer les traitements anti hypertenseurs. L'augmentation des troponines cardiaques est un facteur de mauvais pronostic qui aggrave le tableau. La myocardite est définie par une inflammation myocardique, Les tableaux cliniques sont variables de la forme légère à la forme grave ; les biomarqueurs myocardiques restent un test incontournable en cas de suspicion clinique, le pronostic est incertain avec des formes fulminantes qui peuvent régresser et enfin pour le traitement les corticoïdes semblent être efficaces. Une autre complication du virus sont les accidents thrombo-emboliques et le dilemme occasionné par le risque accru aux thromboses et la thrombopénie induite par l'utilisation de l'héparine (TIH). On note une augmentation de l'incidence des syndromes coronaires aigus chez les sujets atteints du covid19.


The global expansion of covid19 represents a global crisis; this pandemic killed more than a million people in one year. In addition to pulmonary involvement, the virus has major implications on the cardiovascular system: pre-existing cardiovascular diseases represent a risk factor for severe infection with increased mortality, on the other hand the infection causes cardiovascular complications which worsen the prognosis. The link between the Covid19 and the cardiovascular system stems primarily from the virus's cellular entry pathway, which is provided by its binding to a membrane protein, the angiotensin converting enzyme (ACE) wich plays a key role in neurohumoral regulation; this protein is very present in the heart and lungs, hence the tropism of the virus which causes the dysregulation of this cellular pathway with repercussions on cardiac and respiratory function. A controversy broke out concerning the antihypertensive treatments and in particular the inhibitors of the renin angiotensin aldosterone system but after evaluation of the current data, there is a consensus not to withhold or change the treatments. The increase in cardiac troponins is a factor of poor prognosis which worsens the picture. Myocarditis is defined by myocardial inflammation, its clinical form ranges from the mild form to the severe one; the myocardial biomarkers remain an essential when the clinical suspicion rise, the prognosis is uncertain with fulminant forms which can regress; for treatment corticosteroids seem to be effective. Another complication of the virus are thromboembolic events and the dilemma caused by the increased risk of thrombosis and thrombocytopenia induced by the use of heparin (TIH), and there is an increase in the incidence of acute coronary syndromes in patients affected by covid19.

ABSTRACT

Les formes graves de la maladie à Coronavirus (COVID-19) sont souvent associées à une incidence élevée de coagulopathies et de thromboses, dans les dix premiers jours, qui justifie l'intérêt de prévenir les complications thromboemboliques notamment l'embolie pulmonaire (EP), en cours d'hospitalisation. Nous rapportons ici le cas d'une patiente guérie d'une pneumonie à SARS-CoV-2 compliquée d'un syndrome de détresse respiratoire aigu ayant présenté une embolie pulmonaire (EP) à 13 jours de sa sortie de Réanimation. Cette rare observation pose le problème de la nécessité de la surveillance étroite des patients guéris, de la poursuite et de la durée du traitement anticoagulant après la sortie d'hospitalisation et le retour à domicile

ABSTRACT

Background: Cervical cancer is the most common genital tract malignancy in Nigeria and an important cause of cancer­related death in women. Patients with advanced cervical cancer are often victims of deep venous thrombosis (DVT) that increases morbidity and mortality. Strategies at screening and early diagnosis enable prompt treatment which improves quality of life. Objectives: The objective of this study is to determine the plasma D­dimer level in patients with cervical cancer and its relationship to the presence of DVT,Well's score, and stage of malignancy. Materials and Methods: It is a prospective cross-sectional descriptive study of patients with histological diagnosis of cervical cancer in a Nigerian population. Patients' clinical, laboratory, and radiological data were obtained, and their body mass index (BMI) was calculated. Well's chart 17 was used to categorize patients using a cutoff of 2. Plasma D­dimer was quantified by immunoturbidimetric method and interpreted as significant if >0.099 g/dl.High­resolution ultrasound with 5­10 MHZ linear probe was used to evaluate the lower limbs veins of the patients. Data were analyzed with SPSS version 20. The test of association was done using Chi­square with a P < 0.05 considered statistically significant. Results: A total of 77 patients were enrolled, but 67 patients had complete data. The mean age was 54.7 ± 11.2 years. The average parity was 7.5 ± 3.1. Majority (47.8%) had normal BMI. D­dimer was positive in 58 (87%). Of the 17 (25%) with both elevated D­dimer and high probability of DVT, 5 (29%) had DVT. The incidence of DVT among our study population was 7.5%. There was statistically significant relationship between stage of diseaseand an elevated D­dimer value (χ2 = 5.82, α = 0.016, 95% confidence interval). Conclusion: Deep vein thrombosis occurred only in patients with high D­dimer and high Well's score, which makes their combination relevant in early diagnosis. Advanced age, high parity advanced stage of disease was the main associated risk factors. All cases with DVT occurred in patients with squamous cell cancer

ABSTRACT

We report on a patient in whom a giant thrombus in the left atrium was detected by transthoracic echocardiography. Anticoagulant theraphy was started. After two months of therapy; repeat echocardiography showed complete resolution of the thrombus. This case indicates that large and presumably organised thrombi may be treated with anticoagulant the

ABSTRACT

Nous rapportons une observation d'une double thrombose du ventricule gauche et de l'oreillette gauche chez un sujet de 45 ans. Le diagnostic a ete realise grace a une echo-graphie bidimensionnelle Transthoracique qui a mis en evidence un aspect de cardiomyopathie dilatee hypokinetique ainsi que deux volumineux thrombus; l'un tapissant a la pointe du ventricule gauche et l'autre flottant dans la cavite de l'oreillette gauche. Le traitement chirurgical etant inaccessible; un traitement medical a ete institue : anticoa-gulant associe au repos; au regime desode; aux diuretiques; et aux inhibiteurs de l'enzyme de conversion. L'evolution a court terme a ete favorable; sans accident embolique. Mais le pronostic a long terme est reserve et depend de la cardiomyopathie elle-meme

ABSTRACT

Twenty four patients (18 males; 6 females; Mean age 50 years) with acute non traumatic limb ischemia were operated on in our institution. The ischemia has been observed after 24 hours in 15 patients (62;5versus 7 patients (37;5) within 24 hours. The arterial femoral was often (54;1) the site of occlusion. Embolism (29;2) and thrombosis (54;2were the cause of acute limb ischemia. All patients were treated by embolectomy or thrombectomy. The overall mortality was 29;2with a limb salvage rate of 45;8and secondary amputation rate of 29;2. According to our experience; the diagnosis of acute non traumatic limb ischemia is not instituted early and the rate of hospital mortality and morbidity remain high

ABSTRACT

Sonographic findings and clinical outcome of 72 consecutive patients with hepatocellular carcinoma (HCC) in the Yaounde University Teaching during a period of 20 months are reviewed. The purpose of the study was to assess the sonographic pattern and natural history of HCC in Cameroon. The diagnosis was established by fine needle biopsy; or by a combination of clinical features; elevated serum alphafoetoprotein and sonographic findings. There were 55 males and 17 females. Fifty-five (76 per cent) patients presented with hepatomegaly. Three types of HCC were found : nodular; diffuse and mixed. Twenty-two patients had significant ascites. A thrombus in a major portal vein was present in 19 patients. Ten had secondary lesions on presentation. Only one patient was operated on; but the tumour was not resectable

ABSTRACT

La localisation cerebrale des thromboses veineuses est rare au cours de la grossesse et le post partum. Nous rapportons le cas d'une patiente de 33 ans 3eme geste 3eme pare; cesarisee a 34 semaine d'amenorrhee pour placenta praevia hemorragique; les suites post operatoires sont marquees au 6eme jour par des cephalees suivies de crises convulsives et un deficit moteur de l'hemicorps droit. Le diagnostic de thrombose veineuse cerebrale est confirme par l'angio-IRM cerebrale. Le bilan etiologique restait negatif. L'evolution etait favorable sous anticoagulant. Les auteurs mettront l'accent sur les aspects physiopathologiques; cliniques; paracliniques; therapeutiques et evolutifs de la TVC du post partum
