RESUMEN
Introducción: Las mutaciones Leiden y Cambridge del factor V de la coagulación y la resistencia a la proteína C activada (RPCA) son alteraciones que se relacionan con trombosis venosa y arterial. En este trabajo se analizó si la RPCA está asociada con las mutaciones Leiden y Cambridge, y la frecuencia de éstas en población mestiza mexicana.
Material y métodos: Se incluyeron 150 pacientes mexicanos con trombofilia primaria y 100 sujetos sanos. Se determinó la RPCA empleando método comercial y los genotipos factor V Leiden y factor V Cambridge mediante PCR-RFLPs.
Resultados: La RPCA fue positiva en cuatro pacientes y en un individuo control; sin embargo, no se encontró la mutación Leiden o Cambridge en la población estudiada, por lo que la RPCA no se correlacionó con ninguna de las mutaciones investigadas.
Conclusiones: Los resultados indican que existen otras causas primarias o secundarias diferentes a las analizadas, que condicionan la RPCA. Además, la frecuencia obtenida para la RPCA en nuestra población trombofílica mestiza mexicana fue menor comparada con la obtenida en población caucásica, quizá por tratarse de poblaciones genéticamente diferentes.
