Comparative analysis of blood redox parameters according thyroid function of patients with autoimmune thyroid diseases.
Little is known about various blood parameters of oxidative stress and antioxidant defence patients with various thyroid functional states in autoimmune diseases (ATD). To clarify influence of thyroid metabolic status on blood redox parameters, we performed a complex estimation of patients with ATD (Graves' disease and chronic autoimmune thyroiditis). 50 patients with ATD have been studied: 16 - with hyperthyroidism; 20 - euthyroidism; and 14 - with hypothyroidism. 10 healthy subjects were selected as a control group. In patients with hyperthyroidism has been only observed inverse correlation between ceruloplasmin (CP) and thyroid volume (r= -0,5177, p<0,001); in patients with euthyroidism only inverse correlation between CP and FT4 (r= -0,4970, p<0,001). But in patients with hypothyroidism inverse correlation between Fe(3+)-transferrin and TSH levels (r= -0,6501, p<0,001) and direct correlation between nitric oxide and FT4 (r= 0,5657, p<0,001), and lipid peroxyradicals and FT4 (r= 0,5620, p<0,001) have been established. Thus, according to obtained results oxidative stress occurs at ATD in spite of thyroid status. Our findings about association of the thyroid function and REDOX-system should be considered in the treatment of ATD.
