摘要
目的探讨肾脏免疫球蛋白沉积与糖尿病肾脏病(diabetic kidney disease,DKD)的临床相关性。方法将肾活检确诊为DKD的患者分为4组:(1)一阳(IgA+IgM-IgG-/IgA-IgM+IgG-/IgAIgM-IgG+)。(2)二阳(IgA+IgM+IgG-/IgA+IgM-IgG+/IgA-IgM+IgG+)。(3)全阳(IgA+IgM+IgG+)。(4)全阴(IgA-IgM-IgG-)。收集患者的临床资料,分析肾脏免疫球蛋白沉积与DKD的临床相关性,通过DKD的肾脏终点事件评估其对肾脏预后的预测价值。结果全阳组患者的尿蛋白定量明显高于其他3组;单因素COX回归分析示全阳组发生肾脏终点事件的风险更高,多因素COX回归分析示免疫球蛋白沉积对肾脏预后无统计学意义。结论肾脏多种免疫球蛋白沉积增加了DKD尿蛋白的漏出,但与肾脏预后无明显相关性。
Objective To explore the clinical associations between different types of renal immunoglobulin deposition and diabetic kidney disease(DKD).Methods The patients diagnosed as DKD who underwent renal puncture biopsy were divided into four groups,which were as follows:(1)One-positive(IgA+IgM-IgG-/IgA-IgM+IgG-/IgA-IgM-IgG+);(2)Two-positive(IgA+IgM+IgG-/IgA+IgM-IgG+/IgAIgM+IgG+);(3)All-positive(IgA+IgM+IgG+);(4)All-negative(IgA-IgM-IgG-).Clinical data of patients were collected to analyze the clinical correlation between renal immunoglobulin deposition and DKD,and the value of renal endpoint events was assessed to predict renal prognosis in DKD patients.Results The urinary protein quantity of the all-positive group was higher than that of the other three groups.Univariate COX regression analysis showed that the risk of renal endpoint events was higher in all-positive groups,while multi-factor COX regression analysis showed that immunoglobulin deposition had no statistical significance to renal outcome.Conclusion Multiple immunoglobulin deposition in the kidney increased urinary protein leakage in DKD patients,but there was no significant correlation with renal prognosis.
