摘要:

目的 探讨成人过敏性紫癜肾炎(Henoch-Schnlein nephritis,HSPN)预后及其危险因素。方法 对福建医科大学附属第二医院2002年1月至2011年10月经肾活检证实的76例过敏性紫癜肾炎预后及其危险因素进行回顾性分析。结果 平均随访57个月,10例(13.2%)进入终末期肾脏疾病(end-stage renal failure,ESRD)。单因素分析显示,起病时伴高血压、肾功能损害、随访时24 h尿蛋白定量≥1 g和肾小管间质慢性化指数是肾脏预后不良的危险因素,肾脏预后不良与性别、年龄、肾外表现、起病时肉眼血尿、就诊时24 h尿蛋白定量≥1.0 g、肾小球活动及慢性化指数和免疫抑制剂治疗无关。多因素分析显示,肾脏预后不良危险因素包括起病时肾功能损害(OR=10.96,95%CI 1.56~77.26,P<0.05)和肾小管间质慢性化指数(OR=2.77,95%CI 1.20~6.39,P<0.05)。结论 成人HSPN预后较差,预后不良危险因素包括起病时肾功能损害及肾小管间质慢性化指数。

Abstract:

Abstract:Objective To evaluate the clinical outcomes and risk factors in adult patients with Henoch-Schnlein nephritis (HSPN).Methods A total of 76 adult patients with HSPN were enrolled in this study.They were followed up for 22 to 119 months,and the data of their clinical manifestations,renal pathological findings and outcomes were collected.Renal pathological changes were semi-quantitatively graded.Results Ten patients (13.2%) progressed to end-stage renal failure (ESRD).On univariate analysis,factors predicting ESRD were hypertension and renal impairment at presentation,proteinuria ≥1.0 g/d during following-up,and the tubulointerstitial chronicity;after the adjustment,multivariate analysis indicated the following parameters as independent prognostic predictors:renal impairment at presentation(OR=10.96,95%CI 1.56-77.26,P<0.05)and the tubulointerstitial chronicity index(OR=2.77,95%CI 1.20-6.39,P<0.05).No data detected at presentation,including age,sex,macroscopic hematuria,proteinuria ≥1.0 g/d,glomerular activity index and chronicity index were significantly related to ESRD.Conclusion Renal impairment at presentation and the tubulointerstitial chronicity index are risk factors for ESRD.
