摘要
目的:探讨尿中性粒细胞明胶酶相关性脂质运载蛋白(NGAL)在早期检测系统性红斑狼疮(SLE)患者肾脏损害中的临床意义。方法收集124例 SLE 患者(包括 SLE 非肾炎患者及 SLE 肾炎患者),其中男性3例,女性121例,年龄17~68岁,平均45岁。根据不同的病情、临床表现及病理分型,依据诊断标准将其分成 A 组、B组、C 组。其中 A 组为 SLE 非肾炎患者45例,B 组为 SLE 肾炎 I 、Ⅱ型患者42例、C 组为 SLE 肾炎Ⅲ、Ⅳ型患者37例。同时收集100例健康体检者尿液,设为对照组 D 组。用散射比浊法测定各组的尿α1‐微球蛋白(α1‐MG),再用酶免疫法(ELISA)定量测定各组尿中性粒细胞明胶酶相关性脂质运载蛋白(NGAL)。结果 A 、B 、C 、D 各组尿NGAL 分别为3.51±0.49、5.48±0.98、7.89±1.71、3.50±0.39ug/L ;A 组和 D 组间差异无统计学意义(P >0.05);B 组和 D 组间差异有统计学意义(P<0.01);C 组和 D 组间差异有统计学意义(P<0.01);A 、B 、C 三组间差异有统计学意义(P<0.05)。 A 、B 、C 、D 各组尿α1‐MG 分别7.04±1.57、7.68±3.38、14.26±11.21、6.96±1.43 mg/L ;A 、B 、C 、D 各组的尿α1‐MG 的异常升高率分别为0%、11.9%、40.5%、0%,尿 NGAL 的异常升高率分别为8.9%、97.6%、97.3%、6%,由此可见 SLE 患者 B 组和 C 组的尿 NGAL 的异常升高率与尿α1‐MG 的异常升高率之间存在统计学意义。结论尿 NGAL 对于检测 SLE 患者早期肾小管间质损伤的灵敏度高于尿α1‐MG 。
Objective To explore the clinical significance about the urine neutrophil gelatinase‐associated li‐pocalin (NGAL) in early kidney damage of systemic lupus erythematosus (SLE) patients .Methods Collect urine of 124 patients with SLE (including SLE patients without nephritis and SLE nephritis patients)and 100 cases of healthy check‐up ,divided into four groups ,A 、B 、C 、D .A group is SLE patients without nephritis ,B group is SLE patients with I or Ⅱ type SLE nephritis ,C group is SLE patients with Ⅲ or Ⅳ type SLE nephritis ,D group is healthy check‐up .Use Scattering turbidity method to measure α1‐Microglobulin in urine for each groups .Then use enzyme immuno‐assay(ELISA) to quantitatively detect the neutrophil gelatinase‐associated lipocalin in urine for each groups .Results The urinary NGAL content of A 、B 、C 、D group is 3 .51 ± 0 .49 、5 .48 ± 0 .98 、7 .89 ± 1 .71 、3 .50 ± 0 .39ug/L ;There is no significant difference in urine NGAL between A group and D group(P〉 0 .05) .There is significant difference in urine NGAL between B group and D group(P〈 0 .01) ,between C group and D group(P〈 0 .01) ;Among A group 、B group and C group ,there is significant difference in urine NGAL(P〈 0 .05) .The urinary α1‐MG content of A 、B 、C 、D group is 7 .04 ± 1 .57 、7 .68 ± 3 .38 、14 .26 ± 11 .21 、6 .96 ± 1 .43 mg/L ;The urinary α1‐MG abnormal increase rate of Group A ,B ,C ,D is 0% ,11 .9% ,40 .5% ,0% ,the urinary NGAL abnormal increase rate is 8 .9% ,97 .6% ,97 .3% , 6% ;so there is significant difference of SLE patients group B and group C between urinary NGAL abnormal increase rate and urinary α1‐MG abnormal increase rate .Conclusion The urinary NGAL for detection of SLE patients with early renal tubular interstitial damage is more sensitive than the urinary α1‐MG .
