Haemovigilance: the Full Count in Blood Donors at the Ziguinchor Peace Hospital

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. RESUME Introduction. L’hemovigilance des donneurs de sang requiert un ensemble de dispositions qui concourent a la preservation de la sante des donneurs et des receveurs. Parmi celle-ci figure l’hemogramme pre don. Objectifs. Decrire les differents parametres de l’hemogramme chez les donneurs de sang au sein de l’hopital de la paix de Ziguinchor. Patients et methodes. Etude transversale prospective sur une periode de trois mois (septembre  a decembre 2019). Cent dix-sept (117) donneurs : 68  donneurs fideles, 24 nouveaux donneurs benevoles  et  25 nouveaux donneurs familiaux. L’ensemble des analyses a ete effectue avec l’automate de numeration  Mindray BC-5000. Resultats. Nous avons etudie un total de 117 donneurs : 8 de sexe feminin et 109 de sexe masculin (sex –ratio = 13,62).L’âge moyen des donneurs etait de 33,15 ans( extreme de 18 a 57ans). Les anomalies de l’hemogramme retrouvees etaient : l’hypereosinophilie : 12,8%  , la neutropenie : 21,4% , l’anemie :29.6 %, la thrombopenie :12,8 % , la lymphopenie : 1,7%  l’hyperleucocytose : 0,9%, la  microcytose sans  anemie :1,7 %  , anemie microcytaire hypochrome(n=4)  et  normocytaire normochrome(n=30). Il existe une difference significative entre l’anemie et le sexe  (p= 0,048) mais aucune entre elle et le statut (p=0,279). Conclusion: La consultation medicale doit etre completee par un hemogramme pre don a Ziguinchor.
