Estimation of IL-8, IL-38, Vitamin D, TPO Ab, and CRP Levels in Iraqi Hashimoto Thyroiditis Patients

Abstract

Background: Hashimoto's disorder is an autoimmune disease affecting cells of the thyroid gland via the diffusion of the lymphocytes into thyroid cells. Calcitriol is the active form of Vit.D3; there were a strong correlation between low Vit-D levels and development of autoimmune diseases exists and calcitriol supplementation might play a protective role in the pathophysiology of autoimmune diseases. Objectives: This study aimed to estimate the levels of interlukin-8 (IL-8), interlukin-38 (IL-38), Vitamin D, thyroid peroxidase (TPO) Ab, and c-reactive protein (CRP) in Iraqi patients suffering from Hashimoto disease. Materials and Methods: In this study, 90 individuals (males and females) were enrolled, and divided into two groups: Hashimoto's disorder group (60) patients and the healthy control group (30) persons were checked by the physician with the aid of medical history. The levels of TSH, Vit.D3, anti-TPO Ab, T4, IL-8, and IL-38 were measured for all the study groups. Results: A highly significant reduction (P < 0.001) was shown in mean levels of Vit D, T4, and IL-38 among the patient's group in comparison with the controls, whereas a significant reduction (P < 0.05) was revealed in mean levels of CRP among patients in comparison with the controls. Also, the results showed a highly significant elevation (P < 0.001) in mean levels of TSH, IL-8, and anti-TPO antibodies among the Hashimoto disease group in comparison with the controls. Conclusion: Hashimoto disease caused highly significant decreases in mean levels of Vit. D, T4, IL-38, and CRP, whereas there was a highly significant increase in the levels of TSH, IL-8, and anti-TPO antibodies.
