白细胞介素13在原发性肾小球肾炎肾组织中的表达及意义

目的探讨白细胞介素13(IL-13)在几种常见病理类型的原发性肾小球肾炎(PGN)患者肾组织中的表达及其意义。方法采用免疫组织化学法检测81例PGN患者及10例对照组肾组织中IL-13的表达情况,并与各项临床指标进行相关性分析。结果PGN患者肾组织中IL-13表达均较对照组明显增强;IL-13在PGN患者肾组织中的表达与血尿素氮、肌酐水平、24h尿蛋白定量以及肾小球新月体形成呈正相关(r分别为0.325,0.275,0.291,0.231),而与肾小球滤过率(GFR)、血清白蛋白水平呈负相关(r分别为-0.448,-0.296)。结论IL-13参与PGN患者肾组织的炎症反应及肾小球新月体的形成过程,并与肾功能进展及尿蛋白严重程度密切相关。

The expression and effect of interleukin-13 in renal tissues in patients with primary glomerulonephritis

Objective To study the expression of interleukin-13(IL-13) in renal tissues of several common pathologic types of primary glomerulonephritis(PGN).Methods Immunohistochemistry was used to examine the expression of IL-13 in renal tissues of 81 patients with PGN and 10 normal control cases.The correlation analysis was performed with biochemical and pathological indicators.Results Extensive expression of IL-13 was found in renal tissues of patients with PGN.The expression of IL-13 in renal tissues was positively correlated with the concentration of blood urea nitrogen,serum creatinine,the quantitation of urine protein and the crescent formation in glomerular(r=0.325,0.275,0.291,0.231,respectively).It was negatively correlated with glomerular filtration rate and serum albumin(r=-0.448,-0.296,respectively).Conclusion IL-13 participates in the process of inflammation reaction and crescent formation in the renal tissues in patients with PGN,and is correlated with the progression of renal function and the level of urea protein.
