RESUMO
INTRODUCTION: The aim of this study was to evaluate the prevalence of anemia among blood donors at Lomé national blood transfusion center (NBTC) and to identify criteria for controlling hemoglobin level in blood donation candidates. METHODS: We determined the hemoglobin level using HemoCue® 201+. To identify the hemoglobin level control criteria, the judgment parameters were the proportion of anemic donors based on the number of blood donations in the last 12 months and the staining of the conjunctiva. One parameter is considered "critical" and used as a control criterion when more than 30% of donors meeting this parameter are anemic. RESULTS: A total of 1 291 blood donor candidates, predominantly male (89.70%), were included in this study. The prevalence of anemia was 28.12%. This prevalence was 38.71% among women who made 2 donations and 32.27% among men who made 3 donations and who came for a new donation in the year. Anemia was observed in 59.45% of men and 51.56% of women who had slightly colored conjunctiva. CONCLUSION: The prevalence of anemia was high among blood donors at NBTC Lomé. Hemoglobin control is indicated in blood donation candidates with conjunctiva judged to be slightly colored and / or on their 2nd donation (female) and 3rd blood donation (male) within 12 months.
INTRODUCTION: Cette étude avait pour buts d'évaluer la prévalence de l'anémie parmi les donneurs de sang au centre national de transfusion sanguine (CNTS) de Lomé et d'identifier les critères de contrôle du taux d'hémoglobine chez les candidats au don de sang. MÉTHODES: Nous avons déterminé le taux d'hémoglobine (THb) à l'aide de HemoCue® 201+. Pour identifier les critères de contrôle du THb, les paramètres de jugement étaient la proportion de donneurs anémiés en fonction du nombre de dons de sang dans les douze derniers mois et la coloration des conjonctives. Un paramètre est jugé « critique ¼ et retenu comme critère de contrôle du THb lorsque plus de 30 % des donneurs répondant à ce paramètre sont anémiés. RÉSULTATS: Au total 1291 candidats au don de sang, à prédominance masculine (89,70%), étaient inclus dans cette étude. La prévalence de l'anémie était de 28,12%. Cette prévalence était de 38,71% parmi les femmes qui avaient fait 2 dons et de 32,27% parmi les hommes ayant effectué 3 dons et qui étaient revenus pour un nouveau don de sang en l'espace de 12 mois. L'anémie était observée chez 59,45% des hommes et 51,56% des femmes qui avaient des conjonctives peu colorées. CONCLUSION: La prévalence de l'anémie est élevée parmi les donneurs de sang au CNTS de Lomé. Le contrôle du taux d'hémoglobine est indiqué chez les candidats au don de sang ayant des conjonctives jugées peu colorées et/ou qui sont à leur 2ème don (femme) ou 3ème don de sang (homme) en l'espace de douze mois.
RESUMO
To determine the influence of therapeutic phlebotomy on the reduction of vaso-occlusive crises (VOCs) and of hospital admissions of patients with sickle cell disease and to describe how they experience this practice. Descriptive cross-sectional study of 27 patients with sickle cell disease who underwent phlebotomies. We estimated the number of VOCs, hemoglobin levels, and patient response. Among 27 sickle cell patients (24 SC and 3 SS) who underwent phlebotomies, there were 22 men (81.5 %) men and 5 (18.5 %) women, with an average age of 34.6 ±10.9 years (range: 21-56 years). Before the phlebotomies, 23 (85.2 %) had showed signs of hyperviscosity, they had a mean of 5.3 ± 1.02 (range: 3-8) VOCs annually, and their mean hemoglobin level was 14.3 ±1.5g/dl (range: 10.4 g/dl-16.8 g/dl). The mean number of phlebotomies was 4.9±4.11 (range: 1-13). After this treatment, 21 (91.3 %) reported that their signs of hyperviscosity disappeared, and the mean number of VOCs annually decreased to 0.9 ±0.07 (range: 0-2). The mean change in hemoglobin was 1.9 ±0.8 g/dl (range: 0.9-3.2 g/dl). Nine patients (6SC and 3SS), 7 under anti-anemic treatment, initially refused phlebotomy, mainly because they did not understand how it could be useful to reduce the amount of blood in patients with a potentially anemic disease. Phlebotomy has resulted in a decrease in the frequency of VOCs and hospitalizations. It is essential to further popularize it and increase patients' aware of its value in combatting sickle cell disease and thus improve their willingness for and adherence to this treatment.
