Blood safety is a non-negotiable issue worldwide, specifies the World Health Organization (WHO). Africa is both an entity and a multiplicity of situations within and cross-borders. Indeed, most African countries have recent borders and political organizations, after gaining independence in the 60's. Many such countries have maintained various types of links and cooperation programs with former European countries of influence, e.g. France and Belgium among others, which is the case for several countries from the francophone Central and West Africa. Besides, borders do not delineate ethnic groups as many of them migrate, with spread North to South and East to West across several countries, each having representations, ethnologically speaking. Transfusion is an essential supportive healthcare that requires medicine, technicity and logistics. Cooperation can be provided to Francophone Africa though at the expense of recruiting donors upon criteria that do not completely overlap with e.g. those put forward in France and other high-income countries, despite WHO claims for the universal model of Voluntary Non-Remunerated Blood Donation system. Next, the patient profile in intertropical Africa—of which the various francophone African countries—stringently differs from the profile now seen in France, with its younger (but strongly social network-connected) populations and the importance of anemia of all causes but frequently infectious in nature. The frequency of antigens defining blood groups also significantly differs from that in France and the rest of Europa. Last, the carriage of blood transmissible infectious pathogens in sick but also apparently healthy populations seriously complicates the build up of suitable blood component inventory. In the present review, we discuss the universality of blood donation, the specificities of inter-continent cooperation and report on experiences of such cooperation. The French Blood Establishment EFS has taken over earlier initiatives of regional blood services and provides technology and scientific transfer and support to many countries for several decades; the National Institute for Blood transfusion, an education and research institute, has set up collaborative research in several domains but mostly in the domain of blood transmissible infections. We next also present a theoretical view of support named ALEASE, that can be pursued, based on collaborative experiences carried out in the Mediterranean Northern and Eastern areas. ALEASE promotes benchmark between participants. If there is general agreement that cooperation between economically wealthy countries and low-income, developing, countries in the domain of blood and blood transfusion safety, promotion of blood donation, blood component manufacturing, transfusion technology, hemovigilance, etc., tools to achieve this goal can be periodically reviewed based on specific needs for countries and professionals. That also comprise of adapted, sometimes specific, education programs. 相似文献

Plasmodium falciparum expresses many antigens, which elicit various immune responses in exposed individuals, but no simple surrogate marker for protection has yet been developed. In this prospective survey, we looked for immune responses predictive of protection at various stages of progression from parasite inoculation to onset of disease. We studied 110 Senegalese volunteers from an area in which malaria is mesoendemic after they had received eradication therapy. We evaluated 4 protection-related outcomes (reappearance of parasitemia, duration of asymptomatic carriage, time to first clinical episode, and incidence of clinical episodes) in terms of levels of immunoglobulin G (IgG) against 3 crude parasite extracts and 5 conserved antigens during a 5-month period. Kaplan-Meier estimates and age-adjusted regression models showed these 4 outcomes to be associated with different patterns of IgG response to PfEMP3-cl5 (derived from P. falciparum erythrocyte membrane protein 3), PfEB200, MSP-1(19) (derived from merozoite surface protein-1), [NANP]10, infected red blood cell membrane, and merozoite and schizont extracts. It should, therefore, be possible to develop surrogate markers for each end point on the basis of IgG response to a limited number of conserved antigens. 相似文献
