RESUMO

Se comparó el impacto de la normatividad sanitaria en la seroprevalencia de anticuerpos anti-VIH entre donadores de sangre un año antes y otro después de su vigencia. Se tomó una muestra de 4743 sueros de donadores de 6 bancos en Gudalajara, entre junio de 1986 y junio de 1988; 4020 en el primer año y 723 al año siguiente; en el total de la muestra se determinó la presencia de anticuerpos anti-VIH por la técnica de ELISA, y los positivos se confirmaron mediante inmunofluorescencia indirecta y/o inmunoelectrotransferencia. Durante el primer año, la seropositividad fluctuó entre 2.02 y 30.15 por ciento, dependiendo de diferentes factores, a diferencia del segundo año, donde ésta fue de 0.14 por ciento. Se conluye que la obligatoriedad de la detección de anticuerpos anti-VIH y la prohibición de la comercialización de la sangre han sido factores definitivos para disminuir la incidencia del VIH entre donadores de sangre


In Mexico, since may 1986, the mandatory detection of antibodies against HIV in blood and derivates for the use by humans was legislated, one year later the prohibition of blood trade took effect. The impact of the Sanitary Normativity in the seroprevalence of anti VIH antibodies between blood donators one year before and one year after it took result was compared. A sample was taken from 4743 serums of donors of 6 blood banks in Guadalajara between june 1986 and june 1988; 4020 in the first year and 723 the next. In all the samples the presence of anti HIV antibodies was determined by the ELISA assay and the positive ones were confirmed by indirect immunofluoresence and by Western blot. During the first year, the seroprevalence fluctuated between 2.02 and 30.15 percent depending on different factors, differing from the second year where the seroprevalence was 0.14 percent. It is concluded that the mandatory detection of antibodies against imvand the prohibition of blood trade, have been definitive factors to decrease the incidence of VIH in blood donors.
