The relationship between elevated plasma zonulin levels and Hashimoto's thyroiditis

Area of Science:

• Immunology
• Gastroenterology
• Endocrinology

Background:

• Hashimoto thyroiditis (HT) is a common autoimmune disorder.
• Intestinal microbiota plays a role in autoimmune diseases.
• Zonulin regulates intestinal permeability and can increase gut leakiness.

Purpose of the Study:

• To investigate the association between plasma zonulin levels and HT.
• To explore zonulin as a potential biomarker in autoimmune diseases.

Main Methods:

• Compared plasma zonulin levels in 77 HT patients and 66 healthy controls.
• Measured plasma zonulin using ELISA.
• Utilized statistical analyses including Student's t-test, chi-square, and logistic regression.

Main Results:

• Plasma zonulin levels were significantly higher in HT patients compared to controls (p < 0.001).
• Urea, anti-thyroid peroxidase, AST, TSH, free T3, and serum zonulin levels were associated with HT in regression analyses (p < 0.05).

Conclusions:

• Zonulin may serve as a biomarker connecting intestinal permeability to autoimmune disease etiology.
• Further research could elucidate zonulin's role in HT pathogenesis.
