RECEPTOR SOLUBLE DE TRANSFERRINA EN EMBARAZO Y LACTANCIA

(especial para SIIC © Derechos reservados)
Los valores negativos del receptor soluble de transferrina (en el intervalo de referencia) predice en un 99% ausencia de deficiencia de hierro, mientras que un resultado positivo (por encima del intervalo de referencia) identifica deficiencia de hierro en el 100% de los casos.

RECEPTOR SOLUBLE DE TRANSFERRINA EN EMBARAZO Y LACTANCIA

Resumen
La deficiencia de hierro es una forma común de desnutrición en todo el mundo; empero, existe incertidumbre acerca de la manera óptima de identificarla, especialmente en mujeres embarazadas. El receptor soluble de transferrina (RSTf) en suero ha recibido gran atención como una herramienta promisoria para la detección de la deficiencia de hierro. En esta revisión se resumen los hallazgos de un estudio longitudinal del RSTf en mujeres durante y después de la gestación; también se discute su utilidad como prueba diagnóstica durante el embarazo en relación con los datos publicados.

Palabras clave
Receptor soluble de transferrina, concentración de hierro, embarazo, lactancia

SOLUBLE TRANSFERRIN RECEPTOR IN PREGNANCY AND LACTATION

Abstract
Iron deficiency is a common form of malnutrition world wide, but there is uncertainty concerning the optimal way to identify it, especially in pregnant women. The soluble transferrin receptor in serum (sTfR) has received attention as a new promising tool to detect iron deficiency. This overview summarizes the findings from a longitudinal study, of sTfR in women during and after pregnancy, and its usefulness as a diagnostic test during pregnancy is discussed in relation to previous and subsequent published data.

Key words
Soluble transferrin receptor, iron status, pregnancy, lactation
