Hashimoto thyroiditis (HT), which is an autoimmune disease of thyroid gland, has been declared to present with concomitant several systemic diseases. In this study, the coexistence of the Hashimoto disease with the sleep apnea syndrome has been examined. Seven female patients (33-66 year of age) with Hashimoto thyroiditis were evaluated for sleep apnea syndrome. The diagnosis of Hashimoto disease was based on the high titers of anti-thyroid antibodies and histological findings. None of the patients had any complaints of sleep disturbances. Seven healthy subjects with similar age and sex characteristics were taken as the control group. All the patients and the control subjects were undertaken a full polysomnography (PSG). Five patients with HT showed the characteristics of obstructive sleep apnea syndrome (one severe, one moderate and three mild OSAS), whereas no sleep breathing disturbance was found in the control group. These findings suggest that sleep related breathing problems may develop in the patients with autoimmune thyroiditis even if they are euthyroid.
