Abstract
Background. Hashimoto's thyroiditis (HT) is an auto-immune condition characterized with lymphocytic and fibroblastic infiltration of the thyroid gland. The rate of uric acid and HDL cholesterol - so called as uric acid to HDL ratio (UHR) has been shown to be elevated in inflammatory conditions diseases. We aimed to compare UHR and other laboratory parameters of the patients with HT to those values in healthy controls. Methods. The patients diagnosed with HT by medical history, physical examination, elevated thyroid autoantibodies in serum and characteristic sonographic findings in outpatient internal medicine clinics of our institution were enrolled to the present retrospective study. Age and sex matched healthy volunteers were enrolled as controls. UHR of the HT patients and control subjects were compared. Results. The mean UHR of the HT group was 11% ± 4 %, while UHR of the control group was 8% ± 2% (p<0.001). UHR was significantly and positively correlated with thyroid stimulating hormone (TSH) (r=0.26, p=0.01) and negatively correlated with free T4 (FT4) (r=-0.22, p=0.04) levels. The sensitivity and specificity of the UHR level were greater than 8.3%: were 74% and 52%, respectively (AUC: 0.74, p<0.001, 95% CI: 0.64-0.84). Conclusion. We suggest that UHR is a reliable and useful marker for HT. Therefore, it may be helpful in establishing the diagnosis of HT in addition to other diagnostic tools.
