Prohepcidina y estado del hierro e inflamación en escolares sanos o H. pylori positivos asintomáticos

El eje hepcidina-ferroportina es determinante en la homeostasis del hierro. Niveles elevados de hepcidina reducen la capacidad de absorción intestinal del hierro, así como su movilización entre tejidos. Una condición que produce valores séricos elevados de hepcidina es la infección. Como la infecci...
