Abstract:
Objective:To study the expression and clinical significance of serum neutrophil elatinase-associated lipocalin (NGAL), monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-like weak inducer of apoptosis (TWEAK) in patients with lupus nephritis (LN).Methods:97 LN patients who received treatment in Hanzhong 3201 Hospital from January 2016 to December 2019 were selected as study objects. Among them, 38 cases were in the active group and 59 cases were in the inactive group, and 51 cases for physical examination were selected as the control group. The levels of serum NGAL, MCP-1, TWEAK and LN renal function was examined and compared in each group. The diagnostic value of serum NGAL, MCP-1 and TWEAK expression on LN disease activity was evaluated by receiver operating characteristic (ROC) curve.Results:The levels of serum NGAL, MCP-1 , TWEAK, serum creatine (Scr), blood urea nitrogen (BUN), 24 h urinary protein and dsDNA in the active and inactive groups were higher than those in the control group, and the above indexes in the active group were higher than those in the inactive group ( P<0.05). Pearson correlation analysis showed that serum NGAL, MCP-1 and TWEAK levels in LN patients were positively correlated with systemic lupus erythematosus disease activity index (SLEDAI) score, Scr, BUN, 24 h urine protein and dsDNA levels ( P<0.05). ROC curve analysis showed that the area under curve (AUC) of combined serum NGAL, MCP-1 and TWEAK in predicting disease activity of LN patients was 0.865, and the specificity, sensitivity, AUC and Youden index were higher than single index. Conclusions:The expression of NGAL, MCP-1 and TWEAK in LN patients during the active period is increased and closely related to the activity of disease. It is of high application value for predicting LN activity, and can be used as biomarkers for clinical prediction of LN activity.
