ABSTRACT

Se evaluó la seguridad y efectividad de un método manual de recolección de células progenitoras hematopoyéticas de sangre periférica movilizadas con factores estimuladores de colonias granulocíticas (FEC-G) de producción nacional (Leukocim y Hebervital). Se estudiaron 250 pacientes seleccionados para terapia celular en el Servicio de Angiología del Hospital General Docente Enrique Cabrera. La obtención y separación de las células mononucleares autólogas de sangre periférica (CMN-SP) se realizó mediante el método diseñado en el Instituto de Hematología e Inmunología. Para valorar la eficacia del método se analizaron en el concentrado obtenido las variables: contenido de células nucleadas, de células mononucleadas y de células CD 34+. Además, se determinó la viabilidad celular y la contaminación microbiológica. Se comprobó la eficiencia y seguridad del método de recolección y procesamiento para la obtención de un concentrado con un contenido de células mononucleares adecuado, sin complicaciones de importancia clínica. Se demostró la eficacia de los factores estimuladores de colonias granulocíticas empleados. Los efectos adversos de la movilización resultaron ligeros e independientes del factor estimulador utilizado


The safety and effectiveness of a manual collection method of peripheral blood hematopoietic progenitor cells mobilized by the Cuban-made granulocytic colony-stimulating factors (Leukocim and Hebervital) were evaluated. Two hundred patients, who had been selected for the cell therapy at the Angiology Service of Enrique Cabrera General Teaching Hospital, were studied. The method designed by the Institute of Hematology and Immunology served to obtain and separate autologous mononuclear cells from the peripheral blood. For the purpose of assessing the efficacy of this method, the variables contents of nucleate cells, of mononucleate cells and of CD 34+ cells were analyzed in the final concentrate. Additionally, the cell viability and the microbiological pollution were determined. The efficiency and safety of the collecting and processing method for obtaining one concentrate with adequate content of mononuclear cells and no significant clinical complications was confirmed. The efficacy of the Cuban granulocytic colony-stimulating factors was proved. The adverse effects of the mobilization were mild and unrelated to the used stimulating factor
