Graves‘ disease is an autoimmune thyroid disorder characterized by the presence of autoantibodies against thyrotropin receptor. Antithyroid drugs are effective in controlling hyperthyroidism, but only one-third of patients achieve long-term remission after antithyroid drug treatment withdrawal. Influence of demographic factors (such as age and gender) on clinical features and outcome of Graves’ disease remains unclear despite decades of scientific research. The aim of the study was to determine the influence of age and gender on clinical features and outcome of Graves’ disease. Matherial and methods. We performed a retrospective study of 194 adult patients with newly diagnosed Graves’ disease. Outcome after antithyroid drugs was defined as remission or failed. Results. The mean age of males was greater than females (p=0,022). Males and females had the same outcome after medical therapy. The presence of large goiter was associated with lower mean age at diagnosis in both females and males. Patients less than 40 yr. of age were more likely to have large goiter (grade III) than smaller goiter (grade I/II) compared with older patients (OR 2.81, 95% CI 1.35 –5.84). Age at disease onset had no significant relationship with the medical treatment failure. Conclusions. Age less than 40 yr. is a significant predictor for the presence of large goiter at diagnosis. Age and gender did not predict the outcome of Graves’ disease.
