Vitamin D deficiency rates not increased among patients with Hashimoto’s thyroiditis

Rates of vitamin D deficiency were similar among patients with Hashimoto’s thyroiditis and controls, according to study findings published in Endocrine Practice.
Joseph Yasmeh, of the department of medicine at Queens Hospital Center and Icahn School of Medicine at Mount Sinai, and colleagues evaluated 185 patients who visited Queens Hospital Center in New York to determine whether vitamin D deficiency is linked to Hashimoto’s thyroiditis.
Patients were assigned to a control (women, n = 45; men, n = 43) or Hashimoto’s thyroiditis (women, n = 60; men, n = 37) group.
Among women, the mean 25-hydroxyvitamin D level was higher in the Hashimoto’s group compared with controls (P = .013). No difference was found between the groups for men. Women with Hashimoto’s thyroiditis were more likely to be vitamin D sufficient (51.7%) compared with control women (31.1%). Vitamin D insufficiency was more common among control women (68.9%) compared with women with Hashimoto’s thyroiditis (48.3%). No women were vitamin D deficient.
No men were vitamin D sufficient, whereas 5.4% with Hashimoto’s thyroiditis and 7% of controls were insufficient; 94.6% of men with Hashimoto’s thyroiditis and 93% of controls were vitamin D deficient.
“Subjects with [Hashimoto’s thyroiditis] did not have a higher incidence of vitamin D deficiency relative to a control group,” the researchers wrote. “Rather, female [Hashimoto’s thyroiditis] subjects had both a higher rate of vitamin D sufficiency and a lower rate of insufficiency. In male subjects, the mean 25-(OH)D was not different in [Hashimoto’s thyroiditis] and control groups, and both were almost entirely vitamin D deficient.” – by Amber Cox
