BACKGROUND: Omega-3 polyunsaturated fatty acids (PUFAs) produce lipid mediators with both anti-inflammatory and pro-resolution properties, including resolvins. The purpose of this study was to detect serum resolvin E1 (RVE1) levels in Hashimoto's thyroiditis (HT) patients and healthy controls (HCs) and to evaluate the relationship of RVE1 with thyroid autoimmunity.
METHODS: A total of 57 participants were recruited, including 30 untreated HT patients and 27 age- and sex-matched HCs. The levels of RVE1 in serum were measured via enzyme-linked immunosorbent assay (ELISA). An electrochemiluminescence immunoassay was used for the measurement of thyroid-stimulating hormone (TSH), total T4 (TT4), TT3, free T4 (FT4), FT3, anti-thyroid peroxidase antibody (TPOAb) and anti-thyroglobulin antibody (TgAb) levels. Hemogram tests and routine biochemical analyses were performed on each sample.
RESULTS: The serum level of RVE1 of HT patients (24.09, 15.76-34.38 pg/mL) was significantly lower than that of healthy controls (28.51, 20.76-51.23 pg/mL) (P = 0.027). RVE1 levels showed a downward trend with increasing TgAb levels (P for trend = 0.001). Multivariable ordinal logistic regression analysis showed that RVE1 levels were negatively correlated with increasing TgAb levels in both the unadjusted (OR = 0.9446, 95 % CI = 0.9111-0.9782, P = 0.002) and adjusted models (OR = 0.9380, 95 % CI = 0.8967-0.9811, P = 0.005).
CONCLUSIONS: Decreased RVE1 levels might be a sign that HT is associated with inflammatory resolution dysfunction. RVE1 may serve as a protective factor against increased TgAb levels.
