Objective: Hashimotos thyroiditis is a common autoimmune disorder. A few studies have analyzed the association between serum vitamin D levels and Hashimotos thyroiditis and available data remains inconclusive. The aim of this study was to evaluate the association between serum 25-Hydroxy vitamin D levels in pre- and postmenopausal woman with Hashimotos thyroiditis.
Methods: We evaluated 120 premenopausal women with euthyroid Hashimotos thyroiditis (Group 1), 51 postmenopausal women with Hashimotos thyroiditis (Group 2), and the control groups consisted of 102 (74 premenauposal and 28 postmenauposal) age matched healthy subjects; who applied to our outpatient clinic of the internal medicine and endocrinology department. Anti-thyroid peroxidase (TPOAb) and anti- thyroglobuline (TGAb) antibody were positive in all patients. Serum thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), 25-Hydroxy vitamin D and parathyroid hormone (PTH) levels were measured.
Results: In the group 1 the mean vitamin D level was 12.46 μg/L (SD±12.34), compared to 19.467 μg/L (S.D.±8.19) in the control group for premenopausal women, P=0.02 (Table 1). In the group 2 the mean vitamin D level was 18.46 (S.D.±10.97) μg/L, compared to 23.12 μg/L (S.D.±8.60) in the control group for postmenopausal women (Table 2).
