Introduction au Centre National de Transfusion Sanguine de Lomé, le sang total est systématiquement séparé en différents produits sanguins labiles. L'objectif de cette étude était d'évaluer la qualité des concentrés de globules rouges (CGR) qui y sont produits. Méthodes il s'est agi d'une étude transversale réalisée de janvier à mars 2018 qui a porté sur 260 CGR (204 unités adultes et 56 unités pédiatriques). Les poches incluses ont été pesées afin de déterminer le volume de leur contenu. Le taux d'hémoglobine et l'hématocrite ont été déterminés en utilisant l'automate Pentra XLR de Horiba Médical. Nous avons évalué la fidélité et la justesse de l'automate afin d'assurer la fiabilité des mesures des variables analysées. Les analyses statistiques ont été réalisées à l'aide du logiciel R. Résultats concernant les unités adultes, 79,90%; 81,86% et 43,13% des poches étaient conformes respectivement pour le volume, la teneur en hémoglobine et l'hématocrite. Au niveau des unités pédiatriques, 98,21%; 69,64% et 37,50% étaient conformes respectivement pour le volume, la teneur en hémoglobine et l'hématocrite. En considérant les trois paramètres simultanément, on avait un taux de conformité de 42,16% pour les CGR adultes contre 35,71% pour les CGR pédiatriques. Conclusion nous recommandons d'élargir l'intervalle entre deux dons de sang et de mettre en œuvre le contrôle d'hémoglobine avant le don dans les critères d'aptitude au don de sang au CNTS de Lomé.
Introduction: Stem bark of Lannea kerstingii is used in Togo for its anti-anemic effect. The aim of this study was to verify the efficacy of extracts of L. kerstingii’s bark in the treatment of anemia and to explore its mechanism of action. Materials and Method: L. kerstingii stem bark was collected in the city of Kpalimé, located at 120 km northwest of Lomé. Hydromethanolic extract was obtained by evaporation. Two protocols were carried out and 20 twelve-week-old rats that had an average weight of 175.17±16.8 grams were used. The first protocol consisted of inducing anemia in rats by intraperitoneal injection of phenylhydrazine, then force-feeding them with L. kerstingii extract and measuring the effect of this extract on their hemoglobin levels. The second protocol investigated the effect of the extract on the serum hepcidin level, after oral administration of carbon tetrachloride to rats. Hepcidin levels were measured by the ELISA technique. Results: L. kerstingii stem bark extract significantly corrected the anemia induced by phenylhydrazine use: in fact, the anemia of rats that received L. kerstingii extracts was corrected. Control rats that received folic acid had a correction of their anemia too. But, rats that received only saline remained anemic. However, no correlation between the level of extract consumption and the level of hepcidin was established. Conclusion: L. kerstingii bark hydroethanolic extracts increase hemoglobin levels in anemic rats. The main challenge that needs to be solved is determining the minimum dose to be consumed to ensure its effectiveness. Keywords: Lannea kerstingii, anemia, hepcidin, wistar rat.
