Abstract:
Objective:To investigate the relationship between serum endothelia cell-specific molecules (endocan), 8-hydroxy-2′deoxyguanosine (8-OHdG) and restless legs syndrome (RLS) in patients with end-stage renal disease (ESRD) on hemodialysis.Methods:A total of 180 ESRD hemodialysis patients admitted to the Shenyang First People′s Hospital, the Liaoning Electric Power Center Hospital and the Northern Theater Command General Hospital of the Chinese People′s Liberation Army from May 2021 to May 2023 were prospectively selected and divided into RLS group (41 cases) and non-RLS group (139 cases) according to whether RLS occurred. According to the International RLS Rating Scale (IRLS), the patients with RLS were divided into mild group (12 cases), moderate group (19 cases) and severe group (10 cases). Serum endocan and 8-OHdG levels were detected by enzyme-linked immunosorbent assay. Pearson correlation was used to analyze the correlation between serum endocan, 8-OHdG levels and IRLS scores in RLS patients. Multivariate logistic regression model was used to evaluate the influencing factors of RLS in ESRD hemodialysis patients. The diagnostic value of serum endocan and 8-OHdG levels in ESRD hemodialysis patients was analyzed by receiver operating characteristic (ROC) curve.Results:Comparing with the non-RLS group [(4.03±1.23)ng/ml, (0.38±0.13)ng/ml], the levels of serum endocan in the RLS group [(6.10±1.95)ng/ml], 8-OHdG [(0.53±0.14)ng/ml] were higher ( t=8.180, 6.379, P<0.001). The levels of serum endocan of the RLS patients in the mild, moderate and severe groups [(3.61±1.01)ng/ml, (6.39±1.41)ng/ml, (8.54±2.68)ng/ml], 8-OHdG [(0.39±0.07)ng/ml, (0.51±0.05)ng/ml, (0.74±0.08)ng/ml] were increased successively ( F=23.065, 83.013, P<0.001). Pearson correlation analysis showed that serum endocan and 8-OHdG levels were positively correlated with IRLS scores in RLS patients ( r=0.813, 0.830, P<0.001). Multivariate logistic regression analysis showed that long dialysis time, elevated serum endocan and 8-OHdG were independent risk factors for RLS in ESRD hemodialysis patients, and elevated ferritin was independent protective factor (all P<0.05). ROC curve analysis showed that the area under the curve of RLS in ESRD hemodialysis patients diagnosed with serum endocan and 8-OHdG combined was 0.919 (95% CI: 0.870-0.955), which was larger than in patients diagnosed with serum endocan and 8-OHdG alone 0.791 (95% CI: 0.724-0.848), 0.780 (95% CI: 0.712-0.838). Conclusions:The increase of serum endocan and 8-OHdG is related to the occurrence and severity of RLS in ESRD hemodialysis patients. The combined detection of serum endocan and 8-OHdG levels is of high diagnostic value in the occurrence of RLS in ESRD hemodialysis patients.
