【摘要】 目的  探討IgA腎病腎血管病變的危險因素。 方法  回顧性分析2000年1月-2009年6月間經腎活檢確診的175例IgA腎病患者資料,其中有腎血管病變者93例,無腎血管病變者82例,進行對照研究。采用多因素非條件logistic回歸模型分析影響IgA腎病腎血管病變的危險因素。 結果  高血壓[OR=11.593,P=0.001,95%CI(2.800,47.991)]、24 h尿蛋白定量[OR=1.754,P=0.001,95%CI(1.270,2.424)]、血肌酐[OR=1.005,P=0.001,95%CI(1.002,1.008)]、腎小球硬化[OR=8.341,P=0.000,95%CI(2.716,25.610)]、腎間質纖維化[OR=4.880,P=0.014,95%CI(1.385,17.199)]對IgA腎病腎血管病變的影響有統計學意義。 結論  高血壓、24 h尿蛋白定量、血肌酐、腎小球硬化和腎間質纖維化可能是影響IgA腎病腎血管病變的獨立危險因素。積極控制以上危險因素對延緩IgA腎病病變的進展具有重要意義。
【Abstract】 Objective  To explore the risk factors for renal vascular lesions in patients with immunoglobulin A (IgA) nephropathy. Methods  We retrospectively analyzed the clinical data of 175 IgA nephropathy patients diagnosed through renal biopsy from January 2000 to June 2009. Among them, there were 98 cases of renal vascular lesions and 82 cases without renal vascular lesion. Controlled study between the two groups of patients were carried out. A multivariate unconditional logistic regression model was employed to analyze the risk factors for renal vascular lesions in IgA nephropathy patients. Results  The following factors had significant correlations with renal vascular lesions in IgA nephropathy patients: hypertension [OR=11.593,P=0.001,95%CI (2.800, 47.991)], 24-hour urine protein level [OR=1.754,P=0.001, 95%CI (1.270, 2.424)], serum creatinine [OR=1.005,P=0.001, 95%CI (1.002, 1.008)], glomerulosclerosis [OR=8.341,P=0.000,95%CI (2.716, 25.610)], and renal interstitial fibrosis [OR=4.880,P=0.014, 95%CI(1.385,17.199)]. Conclusion  Hypertension, 24-hour urine protein, serum creatinine, glomerulosclerosis and renal interstitial fibrosis were risk factors for renal vascular lesions in IgA nephropathy patients. It will be very significant to actively control all the above risk factors to prevent occurrence of renal vascular lesions.
