Ésta es la principal conclusión de un estudio del North York General Hospital de Toronto (Canadá), que publica “American Journal of Obstetrics and Gynecology”, en el que se incluyeron los datos de más de 260.000 embarazadas cribadas entre las semanas 15 y 20 de gestación. Tras ajustar las tasas de pérdida fetal por edad maternal y amniocentesis, encontraron que las tasas incrementadas con un riesgo estimado de ³ 1 por 1.100 para trisomía 18 y defectos del tubo neural, y de ³ por 130 para síndrome de Down, mientras que el exceso en la tasa de pérdida fetal se estimó en 14%, 3% y 1,5% para estos tres grupos, respectivamente.

El cribado de tres marcadores en suero materno establece precozmente el riesgo de pérdida fetal
La pérdida fetal espontánea se incrementa notablemente en mujeres con alto riesgo para trisomía 18, defectos del tubo neural y síndrome de Down en el suero materno, lo que sugiere que el cribado en el segundo trimestre de gestación de estos tres marcadores podría proporcionar una información valiosa para estratificar los embarazos en función del riesgo de pérdida fetal.
