摘  要:目的探讨狼疮肾炎患者体液中性粒细胞明胶酶相关脂质运载蛋白(NGAL)、单核细胞趋化蛋白-1(MCP-1)和肿瘤坏死因子样凋亡的微弱诱导剂(TWEAK)水平的临床意义。方法采用酶联免疫吸附法检测51例系统性红斑狼疮(SLE)患者的血清和尿中NGAL、MCP。1和TWEAK水平,其中狼疮肾炎27例、非狼疮肾炎24例。并采集临床资料。采用t检验、Mann—WhitneyU检验、Parson和Spearman秩相关分析进行统计学分析。结果①血清NGAL水平狼疮肾炎组为(122±70)ng/ml高于非狼疮肾炎组(56±34)ng/ml(P〈0.01)。血清NGAL与整体SLE疾病活动指数(SLEDAI)评分、肾外SLEDAI评分、肾SLEDAI评分、尿蛋白定量(24h)、血肌酐水平呈正相关(r=0.408、0.431、0.339、0.403和0.585,P均〈0.05),与血清c3呈负相关(r=-0.396,P〈0.01)。尿NGAL水平与慢性指数呈正相关(r=0.719,P〈0.01)。②血清MCP-1狼疮肾炎组(284±13)pg/ml高于非狼疮肾炎组(173±69)p咖l,P〈0.01;尿MCP-1水平在狼疮肾炎组M=1154、(P7541178,如341)pg/mg肌酐高于非狼疮肾炎组M=456、(P75714,如114)pg/mg肌酐(P〈0.01)。血清MCP-1水平与整体SLEDAI评分、肾外SLEDAI评分、肾SLEDAI评分、尿蛋白定量(24h)、血肌酐水平均呈正相关(r=0.340、0.416、0.385、0.574和0.654,P均〈0.05),与血清C3水平呈负相关(r=-0.458,P〈0.01)。尿MCP-1水平与全身SLEDAI评分、肾外SLEDAI评分、肾SLEDAI评分、血清抗dsDNA抗体、尿蛋白定量(24h)、血肌酐水平均呈正相关(rs=0.448、0.429、0.459、0.412、0.375和0.419,P均〈0.05)。尿MCP-1水平与慢性指数呈正相关(r=0.689,P〈0.01)。③6例狼疮肾炎尿中可检测到TWEAK。结论尿NGAL和MCP-1水平升高提示肾脏慢性损伤。血NGAL和血、尿MCP1水平在狼疮肾炎活动时均明显升高,可用于监测狼疮肾炎病情Objective To investigate the clinical significance of neutrophil gelatinase-associated lipoealin (NGAL), monoeyte chemoattraetant protein-1 (MCP-1) and tumor necrosis factor-like apoptosis weak inducer (TWEAK) level in body fluids of lupus nephritis (LN) patients.. Methods Levels of NGAL, MCP-1 and TWEAK in the serum and urine of 51 patients with SLE, including 27 LN cases and 24 non-LN cases, were detected by enzyme-linked immunosorbent assay; and the clinical data were collected. Student's t test, Mann-Whitney U test, Pearson's correlations and Spearman's rank correlations were used for statistical analysis. Results ① The level of serum NGAL in the LN group (122±70) ng/ml was higher than that in the non-LN group (56 ± 34) ng/ml (P〈0.01). There was a positive correlation (r=0.408, 0.431, 0.339, 0.403 and 0.585, P〈0.05) between the serum NGAL and general SLEDAI score, extra-renal SLEDAI score, renal SLEDAI score, the levels of 24-hour urine protein and serum creatinine. There was a negative cor-relation (r=- 0.396, P〈0.01 ) between the serum NGAL and serum C3 level. There was a positive correlation (r=0.719, P〈0.01 ) between urinary NGAL levels and chronic index (CI). ② The level of serum MCP-1 in the LN group (284 ± 113) pg/ml was higher than that in the non-LN group (173± 69) pg/ml, (P〈0.01). The level of urinary MCP-1 in the LN group (M=1154, P75 41 178, P25 341 ) pg/mg creatinine was higher than that in the non-LN group (M=456, P75 714, P25 114) pg/mg creatinine (P〈0.01). There was a positive correlation (r=0.340, 0.416, 0.385, 0.574 and 0.654, P〈0.05) between the serum MCP-1 level and the overall SLEDAI score, extra-renal SLEDAI score, renal SLEDAI creatinine levels. There was a negative correlation score, 24-hour urinary protein excretion level and serum (r=-0.458, P〈0.01) between the serum MCP-1 level and serum C3 levels. There was a positive correlation (r,=0.448, 0.429, 0.459, 0.412, 0.375 and 0.41
