UltramicroELISA para la deteccion de anticuerpos IgM al Mycobacterium leprae utilizando muestras de sangre seca

UltramicroELISA assay for the detection of IgM antibodies to Mycobacterium leprae using eluates of dried blood spots

Resúmenes

En este trabajo se establecen las condiciones optimas para la detección de anticuerpos IgM al glicolipido fenólico-I (GF-I) en muestras de sangre en papel de filtro utilizando el UltramicroELISA HANSEN y la tecnologia SUMA. Se estudiaron 300 donantes de sangre y 58 pacientes leprosos. Para estas dos poblaciones se compararon los resultados de muestras de sangre seca colectadas en papel de filtro SS-2992 con los de suero, y se obtuvo una correlación de 0.919 para donantes de sangre, 0.969 para pacientes y 0.954 para el total de las dos poblaciones. Se obtuvo una coincidencia de 98% en pacientes y 96% en donantes. En la población de pacientes la sensibilidad fue de 93% y la especificidad de 100% para las muestras de sangre seca evaluadas por el UMELISA HANSEN, con respecto a las muestras de suero analizadas por esta misma tecnica.

In this work the adequate conditions for the detection of IgM antibodies to PGL-I in eluates from dried blood spots using the UMELISA HANSEN and the SUMA technology are established. A total of 300 blood donors and 58 leprosy patients samples were studied. For both populations, in the previously established conditions, we compared the results of the eluates from dried blood spots with the serum samples, and was obtained a correlation of 0.919 in blood donors, 0.969 in patients, and 0.954 for the total of both populations. It was also obtained a level of agreemnet of 98% in patients and 96% in blood donors. In the patients population was found a sensitivity of 93% and an specificity of 100% for the eluates of dried blood spots evaluated by the UMELISA HANSEN in the comparison with the serum samples analized by the same assay.
