Intérêt du gradient de concentration sérum-ascite en albumine dans le diagnostic des varices oesophagiennes chez le cirrhotique africain, Abidjan (Côte d'Ivoire)Interest serum-ascites albumin concentration gradient in the diagnosis of esophageal varices in cirrhotic African, Abidjan (Côte d'Ivoire) Résumé Buts : Déterminer la corrélation entre le gradient de concentration sérum-ascite en albumine (GASA) et la prédic-tion des varices oesophagiennes (VO) et autres paramètres de l'hypertension portale (HTP) à savoir signes rouges, grades des varices, varices cardiotubérositaires et les gastropathies d'HTP chez le cirrhotique noir africain en Côte d'Ivoire. Patients et méthode : Etude transversale rétrospective portant sur 113 dossiers médicaux de patients présentant une ascite liée à l'HTP. La fibroscopie digestive haute pour la recherche de signes d'HTP. Le dosage des protéines dans le sérum et le liquide d'ascite a été réalisé par les méthodes chimiques courantes. La sensibilité et la spécificité obtenues par l'aire sous la courbe ROC (Receiver-Operating-Characteristic). Résultats : A 1,1 g/dl, le GASA prédisait les VO avec une sensibilité (53,3%), une spécificité (80%) pour une performance diagnostique faible (64%). A partir de 1,5 g/dl du SAAG, la spécificité était maximale (100%) mais on relevait 40% de faux-négatifs. Pour une valeur-seuil de -1,240 g/dl, la performance diagnostique du GASA était meilleure avec une sensibilité (96%), une spécificité (55%) pour une performance diagnostique à 84%. Conclusion : La valeur seuil du GASA efficace pour la détection des VO était inférieure chez les sujets africains en raison des facteurs nutritionnel et infectieux fréquents dans ces pays à faible revenu.

Patients and Methods: A retrospective cross-sectional study of 113 medical records of patients with ascites associated with PH. The gastroscopy to search for signs of HTP. The protein assay in serum and ascitic fluid produced by standard chemical methods. The sensitivity and specificity obtained by the area under the ROC curve (Receiver-Operating-Characteristic). Results: 1.1 g/dl, the SAAG predicted VO with a sensitivity (53.3%), specificity (80%) for low diagnostic accuracy (64%). From 1.5 g/dl of SAAG, specificity was highest (100%) but fell 40% false-negative. For a threshold value of -1.240 g/dl, the diagnostic performance of SAAG was better with a sensitivity (96%), specificity (55%) for a diagnostic accuracy of 84%. Conclusion: The threshold value of SAAG effective for the detection of VO was lower among African because of frequent nutritional and infectious factors in these low-in...

The students' knowledge of the hepatitis B virus was found to be inadequate and superficial. Early awareness programs provided as part of the official curriculum and measures to improve the social conditions of students should help to improve knowledge in this area.

ABSTRACT

Aims: 1) To assess the feasibility of EPAGE criteria in clinical practice; 2) To assess appropriateness colonoscopy using EPAGE criteria; 3) To compare colonoscopy appropriateness and endoscopic lesions. Method: Hundred thirty-nine consecutive patients explored by colonoscopy were included. The appropriateness of colonoscopy was evaluated by EPAGE criteria. Results: EPAGE criteria were applicable among 127 patients (91% of the cases). Colonoscopies were appropriate, uncertain and inappropriate in respectively 40%; 27% and 24% of the cases. Rate of abnormal colonoscopies was significantly different between the 3 groups (p = 0.03). Cancers were diagnosed exclusively in the groups with appropriate and uncertain colonoscopies (11% and 5%). Colonic adenomas were observed in the three groups (appropriate (7%), uncertain (5%) and inappropriate (6%)). Subjects with uncertain indication were older (58.25 years; p = 0.035). Conclusion: EPAGE criteria are feasible in clinical practice in Cocody's teaching hospital center. Colonoscopies are generally appropriate in our hospital. However, within sight of the significant number of normal colonoscopies and discovered lesions in uncertain indication, colonoscopy cannot concern exclusively calculation of a score of appropriateness.
