Hierro, anemia y eritrocitosis en gestantes de la altura: riesgo en la madre y el recién nacido
DOI:
https://doi.org/10.31403/rpgo.v58i50Resumen
El hierro es un micronutriente necesario para la salud, pero su exceso es dañino. El organismo tiene una alta capacidad de almacenar y reutilizar el hierro corporal, de tal manera que su requerimiento es mínimo (1 a 2 mg absorbido/día). La hepcidina, una hormona producida en el hígado, cumple un rol importante en la homeostasis del hierro inhibiendo a la proteína transportadora de hierro y disminuyendo la absorción de hierro. La anemia materna por deficiencia de hierro se constituye en un problema de salud pública cuando es de magnitud moderada (7 a <9 g/dL) y severa (Hb <7 g/dL), incrementando el riesgo de morbi-mortalidad materna y del neonato. Igualmente, se ha demostrado que niveles altos de hemoglobina en la gestante afecta a la madre y al neonato. En el Perú existe el Programa Nacional de Suplemento con hierro a todas las gestantes, sean o no anémicas. Las evidencias científicas muestran que valores de hemoglobina entre 9 y 10,5 g/dL son óptimas para el mejor crecimiento del feto y que el tratamiento con suplemento de hierro de gestantes no anémicas aumenta los niveles de hemoglobina, el estrés oxidativo y tiene efectos adversos en el recién nacido. Dado que en muchas poblaciones en la altura aumentan los niveles de hemoglobina, se ha sugerido corregir el punto de corte de la Hb para definir anemia. Diversos estudios han mostrado que no sería necesario corregir el punto de corte usado a nivel del mar. En conclusión, los resultados de los estudios no apoyan la necesidad de un suplemento de hierro de forma generalizada a toda gestante. La suplementación con hierro a las gestantes en la altura debería ser evitada si es que la anemia no está claramente demostrada. Se recomienda en cada población de altitud establecer el nivel de anemia y el estatus del hierro corporal, antes de decidir dar un tratamiento con suplemento de hierro.
Palabras clave: Anemia materna, eritrocitosis materna, hepcidina, altura, hierro.
