[The thyroid hormone system in mucoviscidosis].
Endocrine disorders do not represent primary manifestations in children with cystic fibrosis. Abnormal thyroid gland function is commonly observed in patients with chronic nonthyroidal illnesses. Serum concentrations of TSH, T4 and T3 were measured and a TRH-stimulation test (200 micrograms Relefact per kg body weight) was performed in 24 patients with CF 6 to 16 1/2 years of age. As compared to the controls, CF patients had increased basal TSH and lower T4 and T3 concentrations. Finally they exhibited higher TRH-stimulated TSH and decreased peripheral T4 and T3. There was no correlation to the nutritional status or the Shwachman scores. In all patients with CF albumin, TBG and TBPA were also normal. Our results indicate a subclinical hypothyroidism in CF. Routine therapy with thyroid hormones is neither necessary nor recommended.
