Abstract


ABSTRACT
Introduction. Hemovigilance of blood donors requires a set of provisions that contribute to the preservation of the health of donors and recipients. Among these is the pre-donation blood test. Objectives. To study the profile of different parameters of the haemogram in blood donors at the Ziguinchor Peace Hospital.  Patients and methods. Prospective study over a period of three months (September to December 2019). One hundred and seventeen (117) donors: 68 loyal donors, 24 new volunteer donors and 25 new family donors. All analyses were performed with the Mindray BC-5000 automated counting machine. The Chi-square test was used for all data analyzed (significance if p threshold < 0.05).  Results. Total number of 117 donors: 8 female and 109 male (sex ratio = 13.62) The mean age of the donors was 33.15 years (range 18-57 years). The average age of the donors was 33.15 years (extreme from 18 to 57 years). The abnormalities of the haemogram found were: hypereosinophilia: 12.8%, neutropenia: 21.4%, anaemia: 29.6%, thrombocytopenia: 12.8%, lymphopenia: 1.7%, hyperleukocytosis: 0.9%, microcytosis without anaemia: 1.7%, hypochromic (n=4) and normochromic (n=30) microcytic anaemia. There is a significant difference between anemia and gender (p=0.048) but none between anemia and status (p=0.279).  Conclusion. The medical consultation should be completed by a pre-donation blood test at Ziguinchor.


RÉSUMÉ
Introduction. L’hémovigilance des donneurs de sang requiert un ensemble de dispositions qui concourent à la préservation de la santé des donneurs et des receveurs. Parmi celle-ci figure l’hémogramme pré don. Objectifs. Décrire les différents paramètres de l’hémogramme chez les donneurs de sang au sein de l’hôpital de la paix de Ziguinchor. Patients et méthodes. Étude transversale prospective sur une période de trois mois (septembre  à décembre 2019). Cent dix-sept (117) donneurs : 68  donneurs fidèles, 24 nouveaux donneurs bénévoles  et  25 nouveaux donneurs familiaux. L’ensemble des analyses a été effectué avec l’automate de numération  Mindray BC-5000. Résultats. Nous avons étudié un total de 117 donneurs : 8 de sexe féminin et 109 de sexe masculin (sex –ratio = 13,62).L’âge moyen des donneurs était de 33,15 ans( extrême de 18 à 57ans). Les anomalies de l’hémogramme retrouvées étaient : l’hyperéosinophilie : 12,8%  , la neutropénie : 21,4% , l’anémie :29.6 %, la thrombopénie :12,8 % , la lymphopénie : 1,7%  l’hyperleucocytose : 0,9%, la  microcytose sans  anémie :1,7 %  , anémie microcytaire hypochrome(n=4)  et  normocytaire normochrome(n=30). Il existe une différence significative entre l’anémie et le sexe  (p= 0,048) mais aucune entre elle et le statut (p=0,279). Conclusion: La consultation médicale doit être complétée par un hémogramme pré don à Ziguinchor.
