Sažetak

Hashimoto thyroiditis is characterized by anti-thyroid peroxidase (anti-TPO) and
anti-thyroglobulin (anti-Tg) antibodies that gradually lead to thyroid cell destruction. As hypothyroidism
has been associated with insulin resistance (IR), we aimed to investigate whether IR is associated
with thyroid antibody presence and whether the degree of IR correlates with their concentration
in euthyroid individuals. A total of 164 non-diabetic, euthyroid individuals, average age 34 years, were
included in the study, divided into two groups according to Hashimoto thyroiditis and underwent
5-hour oral glucose tolerance test. The degree of IR was evaluated by the Homeostatic Model Assessment
of Insulin Resistance (HOMA-IR). The Hashimoto thyroiditis group had higher HOMA-IR
(p=0.003) and lower glucose levels (p=0.04). HOMA-IR correlated positively with anti-TPO
(p<0.001). Linear logistic regression revealed that anti-TPO concentration increased by 18.13
(p=0.001) with each HOMA-IR unit. IR might trigger thyroid antibody production and Hashimoto
thyroiditis development, which needs to be evaluated in further larger scale follow up studies.
