摘 要:目的肾脏血管损伤,尤其是血栓性微血管病(TMA)是LN中影响肾脏预后的重要因素之一,其中增生性肾炎最容易合并TMA。为了探索增生型LN伴TMA患者的临床特点及对肾脏预后的影响,进行了这项单中心回顾性研究。方法从2013年1月至2016年6月在上海交通大学医学院附属仁济医院南院风湿科进行肾脏穿刺术的146例患者中分别有32例伴有TMA和76例不伴有TMA的增生性LN患者,采集这2组患者的临床、实验室特征、治疗方案及临床结局数据。采用Graphpad 5.0或SPSS 22.0软件对数据进行统计,2组间比较用非参数检验、t检验或Fisher检验。预测因子由多因素回归分析来完成,生存曲线由Kaplan-Meire方法来分析。结果研究发现伴有TMA的患者有更高的肌酐[93.5(69.0,179.8)μmol/L与73.0(56.3,116.3)μmol/L,U=833,P=0.010 1]、B型脑钠肽(BNP)[177(93.2,619)pg/ml与87.5(28.5,255)pg/ml,U=765,P=0.004 6]和尿蛋白量定量(24 h)[4.98(1.99,7.62)g与2.83(1.71, 4.38)g,U=875,P=0.022],更低的补体[C3:(0.37±0.15)g/L与(0.52±0.20)g/L,t=3.713,P=0.000 3;C4:0.056(0.035,0.140)g/L与0.088(0.053,0.167)g/L,U=912,P=0.047 9]、白蛋白[(24±6)g/L与(28±6)g/L,t=3.416,P=0.000 9]和血红蛋白[(88±19)g/L与(99±21)g/L,t=2.627,P=0.015 7],更高的SLEDAI评分[16(13.25,18)与12(10.25,14),U=559,P〈0.000 1],更易出现高血压[(24/32,75%)与(35/76,46%),χ^2=7.613,P=0.006 4],肾脏病理中硬化肾小球更少[0(0,0.038)%与7(0,17)%,U=848,P=0.007 7],急性评分更高[16(14.25,19.75)与13(10,15),U=612,P〈0.000 1];同时这类患者接受更高剂量的激素治疗,且更多患者采用环磷酰胺的诱导方案。多因素回归分析显示肌酐(OR=1.008,P=0.033)和SLEDAI评分(OR=1.272,P=0.003)可能是LN伴TMA的预测因素。在观察的4年期间内,伴�ObjectiveRenal vascular injury, especially thrombotic microangiopathy (TMA), is an im-portant prognostic factors in patients with lupus nephritis. TMA is most likely to be associated with proliferative lupus nephritis. This single-center retrospective study was conducted in order to explore the characteristics and prognosis of patients with TMA associated with proliferative lupus nephritis.MethodsFrom January 2013 to June 2016, 146 hospitalized patients with lupus nephritis underwent renal biopsy in the Department of Rheumatology, South Campus, Ren Ji Hospital, of which 108 were proliferative nephritis including 32 with TMA and 76 without TMA. All the clinical records were collected. All data were analyzed by Graphpad 5.0 or SPSS 22.0 statistical software analysis. Nonparametric test, t test and Fisher test were used for comparison between the two groups. Predictors were analyzed by multiple factors regression analysis, survival curve was analyzed by Kaplan-Meire method.ResultsPatients with TMA were found to have higher levels of creatinine (Cr) [93.5(69.0, 179.8) μmol/L vs 73.0(56.3, 116.3) μmol/L, U=833, P=0.010 1], B-type brain natriuretic peptide (BNP) [177(93.2, 619) pg/ml vs 87.5(28.5, 255) pg/ml, U=765, P=0.004 6], 24-hour urinary protein [4.98(1.99, 7.62) g vs 2.83(1.71,4.38) g, U=875, P=0.022] and highersystemic lupus erythematosus disease activity index (SLEDAI) [16(13.25, 18) vs 12(10.25, 14), U=559, P〈0.000 1], as well as lower complement [C3:(0.37±0.15) g/L vs (0.52±0.20) g/L, t=3.713, P=0.000 3; C4: 0.056(0.035, 0.140) g/L vs 0.088(0.053, 0.167) g/L, U=912, P=0.047 9], albumin (Alb) [(24±6) g/L vs (28±6) g/L, t=3.416, P=0.000 9] and hemoglobin (Hb) [(88±19) g/L vs (99±21) g/L, t=2.627, P=0.015 7]. They were more prone to hypertension [(24/32,75%) vs (35/76, 46%), χ^2=7.613, P=0.006 4], had less glomerular sclerosis [0(0, 0.038)% vs 7(0, 17)%, U=848, P=0.007 7] and higher acute score
