IgA肾病72例临床病理分析

目的对72例IgA肾病的病理进行半定量积分,并对临床表现、病理积分进行相关分析,以指导临床治疗。方法72例分为4组。1组14例:镜下及肉眼血尿组;2组10例:血尿蛋白尿组,尿蛋白<1g/24h;3组31例:慢性肾炎组,尿蛋白1～3.5g/24h;4组17例:肾病综合征组。肾活检标本行HE、PAS、PASM、MASSON染色及免疫荧光检查,病理资料行Katafuchi半定量积分,对蛋白尿、血肌酐、平均动脉压等指标与病理积分进行统计分析。结果①dGAI积分:4组与1组比较P<0.01、与2组比较P<0.05;②急性小球积分:4组与1组比较P<0.01、与2组比较P<0.05;③慢性小球积分:4组与1、2组有显著性差异(P<0.01),3组与1、2组有显著性差异(P<0.01);④慢性间质积分:4组与1组比P<0.05、4组与2组比P<0.01;⑤蛋白尿与急性小球积分r=0.289、慢性小球积分r=0.262;⑥血肌酐与慢性间质积分相关(r=0.654),平均动脉压与慢性间质积分相关(r=0.268)。结论IgA肾病病理变化多样,较多临床指标与肾脏慢性病理积分相关,应该积极治疗急性病理改变,改善预后。

Clinical presentation and pathologic feature of 72 patients with IgA nephropathy

Objective To calculate the semiquantitative scores of renal pathological of IgA nephropathy about 72 patients and to take correlation analysis between clinical presentations and renal pathological indices,acquiring reference for the clinical cure.Method The 72 patients were divided into four groups.Group 1,microcopic and gross hematuria;group 2,24 hour Upro<1 g/24 h;group 3,glomerulonephritis which 24 hour Upro>1 g/24 h,<3.5 g/24 h;group 4,nephritic syndrome.Biopsy specimens obtained were stained by HE,PAS,...
