Thyroid Functions in Behçet's Disease

This study was designed to examine the thyroid hormone levels and TSH secretion in active Behcet's Disease patients. Thirteen patients were included in the study. T3, T4 and TSH determinations were performed with Radioimmuneassay. T3 uptake and free thyroxine indices were calculated for nine patients. Tc99m-thyroid scintigraphies were performed and only one patient has shown presence of left lobe nodular goitre. None of the thirteen patients had clinical signs of thyroid disease. Our results show that thyroid gland functions are not impaired in Behçet's Disease and no additional studies are required at this point.
