Anémie chez les donneurs de sang volontaires après vérification de l'hémoglobine pré-don au Centre de Transfusion Sanguine de Libreville / Anemia in voluntary blood donors after verification of pre-donation hemoglobin at the Libreville Blood Transfusion Center

Introduction : La nécessité de disposer de produits sanguins labiles (PSL) de qualité est un impératif de la transfusion sanguine. Le don de sang n'est pas sans risque pour le donneur. Ce qui soulève la question de la perte de fer par spoliation sanguine. Ce constat a conduit à la réalisation de cette étude dans le but de rechercher l'anémie chez le donneur de sang volontaire jugé apte après évaluation de l'hémoglobine pré-don et d'en déterminer la cause. Patients et méthodes : Il s'agissait d'une étude transversale prospective réalisée au Centre National de Transfusion Sanguine (CNTS) de Libreville. La population d'étude était constituée de donneurs de sang, nouveaux ou anciens, volontaires en bonne santé chez qui les examens suivant ont été réalisés pour le diagnostic de l'anémie et celui de la carence en fer tout en excluant d'autre étiologies: l'hémogramme, le dosage de la Protéine C Réactive (CRP), le fer sérique, la ferritine, l'hepcidine et le test de diagnostic du paludisme (TDR).Résultats : Sur l'ensemble des deux cent quinze volontaires inclus, trente - quatre (15,8%) présentaient une anémie parmi lesquels douze femmes et vingt- deux hommes d'un âge moyen de 32,8 ±8,0. Le nombre de dons effectués était corrélé à la survenue de l'anémie selon le genre et l'âge du donneur. Il en a été de même pour les valeurs de la ferritine, du fer sérique.Conclusion : Le nombre important d'anémie est lié à un seuil bas de l'hémoglobine pré-don. Le caractère microcytaire hypochrome de l'anémie laisse supposer une origine ferriprive.

Introduction: The need to have quality labile blood products (LBP) is an imperative of blood transfusion. Blood donation is not without risk for the donor. This raises the question of the loss of iron by blood spoliation. This finding led to the realization of this study with the aim of looking for anemia in voluntary blood donors deemed suitable after evaluation of the pre-donation hemoglobin and to determine the cause.Patients and methods: This was a prospective cross-sectional study carried out at the National Blood Transfusion Center (CNTS) in Libreville. The study population consisted of blood donors, new or old, healthy volunteers in whom the following examinations were carried out for the diagnosis of anemia and that of iron deficiency while excluding other etiologies: blood count, C-Reactive Protein (CRP), serum iron, ferritin, hepcidin and malaria diagnostic test (RDT). Results: Of the two hundred and fifteen volunteers included, thirty-four (15.8%) presented anemia, including twelve women and twenty-two men with an average age of 32.8 ±8.0. The number of donations made was correlated with the occurrence of anemia according to the sex and age of the donor. It was the same for the values of ferritin, serum iron. Conclusion: The large number of anemia is linked to a low threshold of pre-donation hemoglobin. The hypochromic microcytic character of the anemia suggests an iron deficiency origin.

Early identification and referral of organ donors in five private hospitals: a survey to determine the knowledge and views of critical care professional nurses pre and post a PowerPoint training intervention

Background. Internationally, the declining number of organ donors does not meet the rising demand for life-saving solid organ transplant operations. Critical care professional nurses play an important role in the identification of organ donors. A deeper understanding is needed of the missed opportunities of identification and referral of potential organ donors to organ transplant co-ordinators in the critical care environment. Objectives. To describe the knowledge and views of critical care professional nurses (CCPNs) in South Africa concerning the early identification and referral of organ donors, and to describe the short-term effect of implementing a PowerPoint training intervention on nurses' knowledge in this domain. Methods. A mixed method, experimental, exploratory, descriptive study design was followed. Critical care professional nurses in seven intensive care units at five private hospitals completed a data collection instrument comprising 11 quantitative and three qualitative questions, before and after completing a PowerPoint training intervention. The post test was done directly after the training intervention due to the environment of nursing shift work. Results. A total of 173 (79%) CCPNs participated, from a population of 218. The median (interquartile range) score for all participants increased from 60% (48 - 76) prior to the PowerPoint training intervention, to 96% (88 - 96) after the intervention (p<0.0001). Three main themes emerged from the qualitative questions: stress experienced by the CCPNs during the organ donor process (62%); inadequate collaboration between doctors and nurses (34%); and the need for a policy (9%) to guide the donor referral process. Conclusion. CCPNs' knowledge regarding the early identification and referral of potential organ donors increased significantly following a targeted PowerPoint training intervention. The identified themes suggest that CCPNs require support in order to effectively communicate with the donor's family and medical staff

Critical appraisals and cultural acceptance of the dead donor rule: A revisit of the contemporary transplantation era

Transplantation remains one of the most rapidly expanding surgical specialties. Harvesting organs plays a crucial step in this highly complex surgical and communication process, and the moment at which vital organs can be donated depends on the declaration of end-of-life. This declaration must be performed by medical practitioners on the basis of clear standardized criteria of death confirmation, within competent local and regional jurisdictions, and with the use of confirmatory tests as indicated to ascertain the irreversibility of end-of-life. The current medically and legally accepted definition of death in most societies challenges the traditional and societal understandings of the process of end-of-life. Significant criticisms and cultural oppositions to transplantation still exist, and there is an ongoing debate about the role and the status of transplantation as surgical and medical sciences continue to evolve. By discussing the social acceptance and common understanding of end-of-life determination, we aim to highlight the current knowledge on transplant ethics with respect to the balance between the need to protect the potential organ donor and the need to donate organs at their utmost viability. No report has been done on social acceptance of transplantation in Rwanda or other Low- and Middle-Income countries (LMIC); though, as emphasis on organ transplantation evolves, we also aim to highlight the need for clear directions towards new transplantation regulations. Technical and non-technical critical arguments and moral acceptance are juxtaposed with the elucidated ethical and deontological principles to support the contemporary concept of the dead donor rule

Donor related risk factors on the outcome of living donor liver transplantation

Background & objective: Liver transplantation is an established, effective treatment for acute and chronic end stage liver disease. Donors risk factors should be studied in order not to compromise the procedure of transplantation or to lose candidates for transplantation, the study aims to evaluate the effect of variable donor risk factors on the outcome of Living donor liver Transplantation regarding the morbidity and mortaly .Methods: the current study conducted on 48 patients who underwent living donor liver transplantation for End stage liver disease caused by chronic HCV. Morbidity and mortality were assessed at three and twelve months. Obtained data were studied in correlation with various donor related risk factors, a score designed to collect these risk factors, correlate them with recipient mortality, and graft rejection.Results: high rates of graft rejection and recipient mortality was significantly related to older donor age, donor obesity, donorrecipient gender mismatch, hepatic steatosis, and donor graft recipient weight ratio (GRWR) ≤ 0.8. The designed donor risk score of ≥ 7 was expectedly to associate with poor outcome & recipient mortality.Conclusion: The present study suggested that donor risk score can be a strong predictor of donor related risk factors and its effect on the outcome of Living Donor Liver Transplantation in patients espicially with hepatitis C genotype 4

Incidence of Sexually Transmitted Diseases amongst Potential Semen Donors in University of Benin Tissue Donors Benin City; Nigeria

The incidence of Sexually Transmitted Diseases in Prospective Semen Donors where investigated using Standard Laboratory Procedures. 30 Prospective Semen Donors were screened for common STDs/STI at the Human Reproductive Research Programme /Invitro Fertilization Centre of the University of Benin Teaching Hospital. The incidence rates are Staphylococcus aureus (20); followed by Chlamydia trachomatis (6.7) while Klebsiellia spp; Treponema pallidum; Human Immunodeficiency Virus (HIV); Escherichia coli and Hepatitis B Virus were detected with incidence rate of 3.3each respectively. Ten percent (10) of the prospective semen donors had evidence of polymicrobial infection excluding HIV. The risk of sexually transmitted diseases or infection should be of great concern to couples undergoing therapeutic artificial donor insemination

Iron Deficiency in Frequent and First Time Female Blood Donors

Background: Blood donation has a marked influence on the body iron stores especially in female blood donors . Iron deficiency anaemia is an important limiting factor for the number of donations in female regular blood donors. Aim of the study: This study was conducted to evaluate the frequency of iron deficiency and relevant factors in frequent and first time female blood donors at Casablanca blood transfusion centre; Morocco. Methods: Between November 2005 and April 2006; twenty-one female first time and twenty-one frequent female blood donors were selected randomly. In frequent blood donors; only females with at least 10 donations were included. Haemoglobin concentration; serum ferritin; serum iron and total transferrine binding capacity were measured and analysed. Results: The results of haemoglobin concentration; serum ferritin; serum iron were significant lower in frequent female blood donors when compared with the results of same parameters in first time female blood donors. The results show that the frequency of iron deficiency in frequent female blood donors is 43and in the first time female blood donors is 14. Conclusion: Iron deficiency is very common in regular female blood donors at Casablanca's transfusion centre. Frequent blood donation has marked influence on the body iron stores in frequent female blood donors. It is therefore recommended that blood transfusion centres focused on maintaining iron balance by measuring serum ferritin and total transferrine binding capacity in frequent female blood donors .They have also to educate the donors about iron supplementation and yearly ferritin checking

The Seroprevalence of Cytomegalovirus Antibodies among Prospective Blood Donors in Jos

"Background:Human cytomegalovirus; otherwise called human herpes virus type 5; is a significant cause of morbidity and mortality in pregnancy; and among immunocompromised patients like recipients of organ transplants. Cytomegalovirus is transmissible via blood transfusion; among other parenteral routes. This study therefore aims at establishing the seroprevalence of CMV antibodies among prospective blood donors in Jos. This is with a view to making recommendations on donor screening and transfusion protocols among susceptible patients. Methods: A total of 200 prospective blood donors were recruited into the study. Screening for CMV antibodies was done using ELISA kit; manufactured by ""DIALAB""; Austria (www.dialb.at) Results: Of the 200 prospective blood donors analysed; 184 donors were found to be positive for cytomegalovirus antibodies; representing a prevalence rate of 92.The peak age prevalence was in the 25-29 years age range; representing 0.4.Cytomegalovirus prevalence was lowest in the 15-19 years age range and above 50 years(1.6each). Conclusion: A cytomegalovirus antibody prevalence rate of 92indicates that screening for CMV should be included in screening algorithm for potentially susceptible recipients of blood and its products. Non infected susceptible persons should be transfused CMV negative or leucocyte depleted blood and blood products."
