Selenium levels in patients with autoimmune thyroiditis and controls in lower Austria

Area of Science:

• Endocrinology
• Nutritional Science
• Immunology

Background:

• Autoimmune thyroiditis (AIT) is a prevalent autoimmune condition influenced by genetic and environmental factors.
• The thyroid gland has the highest selenium concentration, and selenium status may impact thyroid pathology.
• Selenium's role in autoimmune thyroid disease pathogenesis warrants investigation.

Purpose of the Study:

• To compare serum selenium levels between AIT patients and a matched healthy control group in Lower Austria.
• To assess if selenium serum levels, as a marker of nutritional selenium supply, differ between these groups.
• To explore the potential association between selenium status and AIT.

Main Methods:

• Serum selenium levels were measured in patients diagnosed with AIT.
• Serum selenium levels were measured in a matched group of healthy individuals from the same region.
• Statistical analysis (t-test) was performed to compare selenium levels between the two groups.

Main Results:

• Mean serum selenium level in AIT patients was 98.0 ± 15.6 μg/l.
• Mean serum selenium level in the control group was 103.2 ± 12.4 μg/l.
• No statistically significant difference (p>0.05) in serum selenium levels was found between AIT patients and controls. Both groups showed mild to moderate selenium deficiency (80-120 μg/l).

Conclusions:

• The study did not find a significant difference in serum selenium levels between AIT patients and healthy controls.
• A weak, statistically insignificant trend suggested slightly higher selenium levels in controls, insufficient to link inadequate selenium supply to AIT.
• Further research may be needed to fully elucidate the complex relationship between selenium status and autoimmune thyroid disease.
