Healthy Women Clinical Trial
Official title:
Study of Serum Hepcidin Rate Variations During Menstrual Cycle
Hepcidin is the major hormone regulating Iron Metabolism. In a normal organism decrease iron
stock causes a decrease in hepcidin synthesis thus promoting intestinal absorption of iron.
The interpretation of hepcidin dosage results requires to know the physiological variations
of this hormone.
This study investigate whether there are significant variations in the values of serum
hepcidin rates during the menstrual cycle in order to make recommendations on the practical
dosage determination of hepcidin in premenopausal women.
Hepcidin is the major hormone regulating Iron Metabolism. Synthesized primarily by
hepatocytes, it interacts with the cellular iron exporter ferroportin, causing its
internalization and preventing the release of iron from enterocytes and macrophages.
In a normal organism decrease iron stock causes a decrease in hepcidin synthesis thus
promoting intestinal absorption of iron.
Since valid methods for the determination of hepcidin serum rate are available, this dosage
is increasingly used to diagnosis iron metabolism pathologies, in particular iron overload.
The interpretation of hepcidin dosage results requires to know physiological variations of
this hormone.
Several works have shown that hepcidin varies according to a circadian cycle, that its
values differ by sex and, in women, by age. As far as the investigators know, no study has
focused on possible variations in serum hepcidin rates values during menstrual cycle in
women. Yet this question seems relevant since it has been shown that during the menstrual
cycle blood loss can cause significant iron and hemoglobin variations, which can
significantly modulate the synthesis of hepcidin.
This study investigate whether there are significant variations in the values of serum
hepcidin rates during the menstrual cycle in order to make recommendations on the practical
dosage determination of hepcidin in premenopausal women.
