摘要

Aim of the workConsidering the importance of toll-like receptor (TLR) 4 and oxidative stress in the pathogenesis of autoimmune disorders, present study was designed to assess serum TLR4, 8-hydroxy-2′-deoxyguanosine (8-OHdG) as a marker of oxidative DNA damage, and total antioxidant capacity (TAC) in rheumatoid arthritis (RA) patients and to study their relation with disease activity and their predictive potential.Patients and methods44 RA patients and 44 matched controls were studied. Disease activity score (DAS-28) was assessed. Serum TLR4, 8-OHdG and TAC were measured.ResultsThe mean age of patients was 44?±?10.4?years, 33 females and 11 males with and disease duration 5.5?±?3.8?months. The mean DAS-28 was 4.6?±?0.6 (3.45–6.01). Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) were both positive in 20 patients. Compared to control, the mean?±?SD of serum TLR4 (2.41?±?4.50 vs. 1.20?±?1.67?ng/ml), and 8-OHdG (67.67?±?20.57 vs. 45.34?±?30.61?ng/ml) were significantly higher in patients (p?

Ng / ml)患者显着高(P?<→0.001);虽然血清TAC(1.3?±0.5与2.01?±0.55?μmol/ L)显着降低(p?<0.001)。 TLR4,8-OHDG显着增加,阳性RF /抗CCP的患者与阴性相比,TAC降低(P?<〜0.001,P?0.005和P?= 0.036)。较高DAS-28的患者(p?= 0.003),TLR4显着高,两者都显着相关(P?<〜0.001)。 TLR4的ROC曲线下的区域(0.87; 95%CI:0.78-0.96)和8-OHDG(0.88; 95%CI:0.79-0.97)大于TAC(0.19,95%CI:0.09-0.29) (p?<〜0.001)。结论TLR4,8-OHDG和TAC在RA病中显示出高预测值。 TLR4可以作为确定RA中的疾病活性的敏感和特异性标记。
