Iodine is an essential element in thyroid homeostasis, particularly in pregnant woman and her fetus. Various studies have clearly shown that antenatal thyroid disorders at both the mother and the fetus could cause in extreme situations of neurological consequences.
At a broader scale, subtle alterations of thyroid hormone balance has been implicated in developmental delays and deviations of the IQ bell curve in newborn infants of mothers with elevated TSH.
The clinical implications of these basic data and public health are yet to confirm.
It has been clearly established that there is a moderate iodine deficiency in France with a decreasing gradient from west to east. In the Ile de France, there is a moderate iodine deficiency, this has led some teams to propose a systematic supplementation of all women in iodine.
One way to target women who really need supplements systematic determination of urinary iodine tongue; this assay is reliable but is difficult to implement in an ad hoc practice at the individual level.
Our team has expertise in the field of fetal thyroid, particularly in its sonographic and reference curves of the perimeter and diameter of the thyroid are now clearly established reliably.
Knowing that iodine deficiency is causing a decline in maternal urine iodine with a phenomenon goitrigénèse and biological hypothyroidism and that some studies have shown that neonatal thyroid volumes were higher in iodine deficient mothers . We postulate that the measurement of fetal thyroid by our criteria can be correlated with maternal urinary iodine.
If this were the case, we will have a simple test to identify iodine supplementation in pregnant women.
