Abstract BACKGROUND: Epidemiological studies on the association between Turner syndrome (TS) and Graves' disease (GD) are sparse and no studies are available on the clinical course of GD in TS. OBJECTIVES: To retrospectively investigate the GD prevalence in children and young adults with TS and to compare the GD course in patients with or without TS who were followed up for 4.1 ± 0.6 and 4.5 ± 3.7 years, respectively. DESIGN: The prevalence of GD in 408 TS patients was evaluated; presentation and evolution of GD under therapy were evaluated both in 7 patients with TS (group A) and in 89 patients without TS (group B). RESULTS: (a) The prevalence of GD in TS patients was 1.7%; (b) GD in TS was not associated with a specific karyotype; (c) with respect to group B patients, those of group A exhibited at presentation more advanced age, a lower fT4 level and more frequent association with other autoimmune diseases, and (d) the clinical course under methimazole therapy was not different in the two groups. CONCLUSIONS: The prevalence of GD in children and young adults with TS is 1.7% and in TS patients, GD presents later and its clinical course is not different than in those without TS.
