UnlabelledThe role of vitamin D (VD) in the etiopathogenesis of autoimmune diseases (AI) is extensively studied. However, its association with autoimmune thyroid disease (AITD) is still controversial. AIM of this study was to assess the relationship between the vitamin D status and thyroid autoimmunity in Slovak premenopausal women with newly diagnosed AITD.Subjects And MethodsThis prospective case-control study included 57 women with AITD and 41 age- and BMI-matched controls. All subjects were examined for summer and winter serum 25(OH)D, thyroid autoantibodies (a-TPO, a-TG), freeT4 and TSH concentrations. Thyroid volume was measured by ultrasound.ResultsThere were no significant differences in serum 25(OH)D between AITD and control groups. No significant correlation between 25(OH)D and thyroid autoantibodies was found either in the whole cohort or in AITD women. The prevalence of vitamin D insufficiency was 60.31 % in AITD women and 52.5 % in the control group. No significant association between VD and thyroid autoantibodies, thyroid hormones and thyroid volume was detected in this study.ConclusionAuthors conclude that VD insufficiency is common in Slovak premenopausal women independently of the presence of AITD. Vitamin D insufficiency is not associated with thyroid autoimmunity in patients with early diagnosis of AITD (Tab. 3, Ref. 31).
