Association of TTGA (Tissue Transglutaminase Antibody) and Histopathologic Findings in Thyroidectomy Patients

Not Applicable

• Conditions: Thyroid Fibrosis

• Registration Number: NCT04974255
• Lead Sponsor: Diskapi Yildirim Beyazit Education and Research Hospital

Brief Summary

Gluten sensitivity is the most common auto-immune disease associated with auto-immune thyroiditis. This association is through elevated anti-Tissue transglutaminase (Anti-tTG) levels both in Celiac disease and thyroiditis. In our study we tried to find if there is any correlation in between Anti-tTG and degree of fibrosis in thyroid tissue (Post-operative specimen).

Detailed Description

Most common auto-immune disease associated with Celiac disease is autoimmune thyroiditis. This association in between Celiac disease and aout-immune thyroiditis is related with asymptomatic rise in anti-tTG levels. In our study, we planned to show that if there is any correlation of thyroiditis related fibrosis in thyroid tissue with anti-tTG IgA ( immune-globulin A) and IgG (immune-globulin G).
