[Transient biological hypothyroidism in an infant carrier of celiac disease]

This is the first report of a coeliac infant with biochemical findings of primary thyroid failure (decreased T4, decreased FT4, decreased T3, increased TSH). No clinical signs of this disorders and no thyromegaly were observed. Biochemical indices of thyroid function reverted to normal after two months on a gluten-free diet. Thyroid function impairment is suggested to be related with the active phase of coeliac disease.
