Abstract:
Objective:To investigate the correlation between serum neutrophil to lymphocyte ratio (NLR), thrombospondin 1 (TSP-1), miR-210 and systemic lupus erythematosus disease activity index (SLEDAI) and the prognostic value of their combination.Methods:The medical records of 126 patients with systemic lupus erythematosus (SLE) in Haikou People′s Hospital (Haikou Hospital Affiliated to Xiangya Medical College of Central South University) from February 2018 to February 2020 were retrospectively analyzed. According to the recurrence of prognosis 6 months after treatment, they were divided into recurrence group ( n=23) and non recurrence group ( n=103). The general data, serum NLR, TSP-1, miR-210 levels and SLEDAI score before and after treatment of the two groups were compared. The relationship between the levels of serum indicators before and after treatment, SLEDAI score, prognosis and recurrence of SLE patients were analyzed, and the efficacy of single and combined serum indicators in predicting prognosis was explored. Results:The levels of serum NLR, TSP-1, miR-210 and SLEDAI score in the recurrence group were higher than those in the non recurrence group before and after treatment (all P<0.05); After treatment, the levels of serum NLR, TSP-1, miR-210 and SLEDAI score in the two groups were lower than those before treatment (all P<0.05). Pearson correlation analysis showed that the levels of serum NLR, TSP-1 and miR-210 in SLE patients were positively correlated with SLEDAI scores (all P<0.05); Cox regression analysis showed that after adjusting other factors such as complement C3, complement C4 levels and SLEDAI scores before and after treatment, serum NLR, TSP-1 and miR-210 before and after treatment were still significantly correlated with the risk of recurrence in SLE patients (all P<0.05); The receiver operating characteristic (ROC) curve showed that the area under curve (AUC) of serum NLR, TSP-1 and miR-210 combined to predict recurrence was 0.907 (95% CI: 0.842-0.951), the sensitivity was 86.96%, and the specificity was 83.50%, which was significantly higher than that of each index alone. Conclusions:Serum NLR, TSP-1, miR-210 levels in SLE patients are positively correlated with SLEDAI scores, and the combined detection of these indicators has a high predictive value for prognosis and recurrence, which can provide references for the diagnosis and treatment of SLE.
