摘要
目的研究新月体形成后过敏性紫癜肾炎(HSPN)患儿的实验室指标和病理特征的变化,并探寻预测新月体形成的无创性生物标志物。方法选取2018年1月—2023年7月住院的HSPN患儿278例,根据新月体形成情况,分为新月体形成组(196例)和无新月体形成组(82例),并将新月体根据形成类型分为细胞性新月体组(52例)和细胞纤维性新月体组(144例)。比较各组间的实验室指标和病理特征,分析各个指标与新月体形成比例间的相关性,采用Logistic回归分析新月体形成的影响因素,绘制受试者工作特征(ROC)曲线,评价实验室指标预测新月体形成的效能。结果与无新月体形成组相比,新月体形成组24 h尿蛋白定量(24 hUP)、尿免疫球蛋白G/肌酐(UGCR)、尿红细胞计数(URBC)、中性粒细胞/淋巴细胞比值(NLR)、血尿素氮(BUN)、三酰甘油(TG)明显升高,出现弥漫性系膜增生(Mb)、肾小管萎缩或间质纤维化(T1)的占比增高(均P<0.05);与细胞性新月体组相比,细胞纤维性新月体组的肾小球节段性硬化或粘连(S1)和T1的占比增高,新月体形成的比例较高,细胞性新月体组毛细血管内皮细胞增生(E1)占比降低(均P<0.05)。Spearman相关性分析显示,24 hUP、UGCR、URBC、NLR、BUN、TG、Mb及T1与新月体形成比例呈正相关(均P<0.05)。多因素Logistic回归分析结果显示,UGCR升高、T1是新月体形成的危险因素;UGCR预测新月体形成的曲线下面积(AUC)为0.731(95%CI:0.667~0.795,P<0.05),最佳截断值为5.00 mg/mmol,敏感度0.744,特异度0.610。结论UGCR可作为一种辅助评估HSPN患儿新月体形成的无创性生物标志物。
Objective To investigate changes of laboratory indicators and pathological features of Henoch-Schonlein purpura nephritis(HSPN)children after crescent formation,and to explore non-invasive biomarkers for predicting crescent formation.Methods A total of 278 children with HSPN who were hospitalized from January 2018 to July 2023 were selected and divided into the crescent formation group(196 cases)and the non crescent formation group(82 cases)based on their crescent formation status.Patients in the crescent formation group were sub-divided into the cellular crescent formation group(52 cases)and the cellular fibrous crescent formation group(144 cases)based on the type of crescent formation.Laboratory indicators and pathological characteristics were compared between different groups.The correlation between each indicator and the proportion of crescent formation was analyzed.The influencing factors of crescent formation were analyzed by Logistic regression.Receiver operating characteristic(ROC)curves were plotted,and the effectiveness of laboratory indicators in predicting crescent formation was evaluated.Results Compared with the non crescent formation group,24-hour urine protein quantification(24 hUP),urine immunoglobulin G/creatinine(UGCR),urine red blood cell count(URBC),neutrophil/lymphocyte ratio(NLR),blood urea nitrogen(BUN)and triglycerides(TG)were significantly increased in the crescent formation group.There were increased proportion of diffuse mesangial hyperplasia(Mb),renal tubular atrophy or interstitial fibrosis(T1)(P<0.05).Compared with the cellular crescent group,the proportion of glomerular segmental sclerosis or adhesion(S1)and T1 were increased,and the proportion of crescent formation was higher in the cellular fibrous crescent group.The proportion of capillary endothelial cell proliferation(E1)was decreased in the cellular crescent group(P<0.05).Spearman correlation analysis showed that 24 hUP,UGCR,URBC,NLR,BUN,TG,Mb and T1 were positively correlated with the proportion of crescent formation(all P<0.05).The results of multivariate Logistic regression analysis showed that elevated UGCR and T1 were risk factors for crescent formation.The area under the curve(AUC)predicted by UGCR for crescent formation was 0.731(95%CI:0.667-0.795,P<0.05),with an optimal cutoff value of 5.00 mg/mmol,sensitivity of 0.744 and specificity of 0.610.Conclusion UGCR can be used as a non-invasive biomarker to assist in evaluating crescent formation in children with HSPN.
