“…The mean number of blood units processed annually per center in each country varied from 884 to 37,477 (median 4478, Table 3). Given that smaller centers are more prone to producing inaccurate laboratory testing results 33,34 and to being financially inefficient, 35 assessing the availability of blood and the operational efficacy of such processing systems is important. Using the number of blood processing centers/100,000 inhabitants as an indicator, it becomes clear that countries with blood center density indexes (BCDI) higher than the median process fewer units per center, have lower proportions of VBD, defer more prospective donors, have higher prevalence of TTI markers, prepare fewer components per unit, and discard more RBC due to expiry as compared to countries with indexes lower than the median ( Table 3, Chi 2 =14.93, p <0.0001).…”

“…42 Fewer processing centers are easier to oversee and make it easier to standardize operating procedures, implement quality assurance, hire specialized personnel, purchase and maintain equipment, procure consumables, acquire automated technology, manage donor and product information, reduce inequity in access to blood, and interact with public health and plasma fractionation institutions. [33][34][35] The lessons described above are likely applicable in other parts of the world.…”

The safety of blood used for transfusions has historically been the main focus of the international health community. In the Americas, during the first decade of the 21st Century, the attention switched to the patients who need transfusions and to the individuals who donate blood, that is, to transfusion safety. Timely and universal access to blood components implied adequate availability to sufficient blood components by patients who require transfusions in every hospital of every country. Clinical conditions and local non-medical factors influence decisions to admit and transfuse ill individuals. Locally-developed pertinent transfusion guidelines contribute to better estimate blood needs. Replacement blood donation hinders access to blood stocked in the hospitals blood banks and results in excessive component expiry and financial losses. Focusing on patient transfusion needs and on patient outcomes permits implementing national blood collection, processing and distribution, in consonance with the national health system. Analyses of general health conditions, by using the national Human Health Indexes, and the operational characteristics of blood services, by using the blood center density index, permit identification of locally pertinent interventions to improve transfusion safety. For this article, the analytical approaches used in Ibero-America were applied to blood data from SouthEast Asian and African countries. Data collection and validation were identified as priorities for Asian countries. Estimating blood component requirements at the local level and adjusting blood collection, processing and distribution systems are important in Africa.

“…La frecuencia de microsporidiosis intestinal encontrada en este estudio (3,9%) en un período de un año fue relativamente baja, semejante a la de 3,5% reportada por Flórez et al, cifras comparables con los estudios realizados en países en donde la prevalencia de sida es similar a la de Colombia (32,(45)(46)(47)(48)(49)(50)(51). En Brasil (48) y Venezuela (52) que son países que presentan tasas más altas de pacientes positivos para VIH, se han informado prevalencias de microsporidiosis de 27,5% y 50%, respectivamente; por consiguiente, se debe tener en cuenta que a medida que aumenten los casos de sida incrementará, probablemente, la microsporidiosis intestinal en estos pacientes.…”

“…Con el fin de prevenir la transmisión de agentes infecciosos mediante la transfusión, las técnicas de tamización utilizadas en los bancos de sangre han mejorado considerablemente, gracias al uso de anticuerpos monoclonales, proteínas recombinantes, péptidos sintéticos y novedosos sistemas de detección, con lo que se han obtenido pruebas mucho más sensibles, específicas y confiables (13).…”

Palabras clave: transfusión sanguínea, hepatitis B, bancos de sangre. Colombia. Absence of occult hepatitis B in Colombian blood donorsIntroduction. In Colombian blood banks, screening for the surface antigen of hepatitis B is mandatory in all units collected. Testing of antibody against core antigens is not administered, although this method may be useful to detect donors infected with the hepatitis B virus. Objective. The prevalence of occult hepatitis B was determined by applying a full-serological profile of hepatitis B virus to blood samples of blood donors. Materials and methods. Between April 2008 and October 2009, a prospective cross sectional study was conducted using 628 samples from donors to blood banks located in four Colombian cities. Prevalence for hepatitis B had been previously recorded for these cities. Serological screening was performed for the complete virus; then nucleic acid amplification was tested in sera that were anti-HBc reactive and with a titer of anti-HBs ≤30 mUI/ml. Results. Of the 628 samples tested, 129 met the serological criteria established to be tested nucleic acid amplification. None of them demonstrated evidence of nucleic acid amplification of hepatitis B virus. Conclusions. This is the first study in Colombia to detect the presence of blood donors that may be occult hepatitis B carriers. None was detected.
