Vitamin D deficiency in thyroid autoimmune diseases

Area of Science:

• Endocrinology
• Immunology

Background:

• The relationship between vitamin D deficiency and autoimmune thyroid diseases remains unclear despite extensive research.
• Existing literature shows increasing data on this correlation, yet definitive conclusions are lacking.

Purpose of the Study:

• To evaluate vitamin D status in patients with autoimmune thyroid disease.
• To investigate potential correlations between vitamin D levels and thyroid function markers (TSH, FT4) and antibodies (ATPO).

Main Methods:

• A retrospective study involving 60 patients (32 with autoimmune thyroid pathology, 28 controls).
• Analysis of vitamin D levels, thyroid stimulating hormone (TSH), free thyroxine (FT4), and anti-thyroid peroxidase (ATPO) antibodies.

Main Results:

• Vitamin D levels were, on average, higher in patients with autoimmune thyroid pathology compared to controls, but this difference was not statistically significant (p=0.197).
• A high prevalence of vitamin D deficiency was observed in both groups, with a slightly higher rate in the control group, also without statistical significance.

Conclusions:

• The study did not establish a statistically significant correlation between vitamin D levels and autoimmune thyroid disease or its markers.
• High vitamin D deficiency prevalence underscores the need for further investigation in both patient populations.
