Acción de los antiagregantes plaquetarios sobre el recuento de plaquetas en el plasma rico en plaquetas.

Abstract

Objetivo: Evaluar el recuento plaquetario en el plasma rico en plaquetas (PRP) de sujetos sanos antes y después de la administración de antiagregantes plaquetarios. Material y método: Se estudiaron 32 sujetos, 20 de sexo femenino y 12 de sexo masculino, entre 18 y 50 años, y aparentemente sanos. Se distribuyeron en dos grupos: 1) 16 sujetos que recibieron aspirina (100 mg) y 2) 16 con clopidogrel (75 mg), administrados en dosis única. En cada uno se extrajo 16,5 ml de sangre venosa antecubital para recuento plaquetario en sangre periférica y en PRP, se practicó agregación plaquetaria antes del tratamiento. Resultados: En todos los sujetos estudiados, se encontró un contaje de plaquetas antes del tratamiento con antiagregantes en sangre periférica de 276,55 ± 66,43 x mm3 y 24 horas después de 281,38 ± 81,55 x mm3. El PRP de los sujetos antes de recibir aspirina fue de 566,86 ± 109,16 x mm3 y después de 526,34 ± 90,55 x mm3; antes de la ingesta de clopidogrel, fue de 444,76 ± 100,65 x mm3 y 388,82 ± 71,94 x mm3 después del tratamiento. Se halló una diferencia significativa para el conteo plaquetario solo para el clopidogrel (p < 0,05). La correlación para el conteo de plaquetas antes y después del tratamiento existe solo para aspirina (r = 0,88). Conclusiones: En el presente trabajo, se evidenció una disminución significativa del recuento plaquetario después de administrar clopidogrel, sin correlación antes y después del tratamiento. Son necesarios más estudios que permitan evaluar un mayor número de casos y su efecto sobre la agregación plaquetaria.
