目的探究7岁以下小儿肾小球疾病的病理特点与临床研究。方法在医院临床儿科2016年2月至2019年2月诊断为10种肾小球疾病患儿中选取68例,并对这68例患儿进行肾组织相关的病理检查。通过对患儿进行经皮肾活检术,对患儿穿刺后提取的肾组织分为三个部分,并对选取的所有患儿进行免疫荧光、光镜以及电镜等检查,其标本分别包括PASM、HE、Masson染色及PAS,同时都利用免疫荧光来进行检测患儿肾组织里的IgA、IgG、IgM、Firibn、C3以及C4,有些患儿则依据血化验乙肝抗原性添加免疫荧光来进行检测其肾组织里的HBeAg、HBcAg以及HBsAg。其中有63患儿接受了电镜检查。结果 68例患儿的主要临床表现特点所占比例分别为:紫癜性肾炎(25.00%)、孤立性血尿(10.29%)、肾病综合征(41.18%)、孤立性蛋白尿(4.41%)、遗传性肾病(4.41%)、乙肝肾(1.47%)、急性肾炎综合征(7.35%)、慢性肾炎(1.47%)、狼疮性肾炎(1.47%)、急进性肾炎(2.94%);患儿病理类型分别为:C3肾病(2.94%)、系膜增生性肾脏肾炎(7.35%)、微小病变(44.12%)、IgM肾病(4.41%)、IgA肾病(7.35%)、局灶节段性肾小球硬化(7.35%)、Alport综合征(4.41%)、薄基底膜肾病(1.47%)、肾淀粉样变(1.47%)、新月体性肾炎(4.41%)、肾型过敏性紫癜(继发性IgA肾病)(14.71%)等。结论在临床中,临床疾病表现相似但是其病理类型却并不相同,同时相同的疾病病理类型,其临床表现多种多样。对7岁以下的患儿利用肾活检术进行肾小球疾病的估计预后、诊断以及治疗都占据着相当重要的地位,同时在进行肾病理检查的过程中利用电镜检查也是非常重要的。 相似文献

In order to characterize their relationship through clinicopathological comparison between IgA nephropathy and Henoch-Sch?nlein purpura nephritis (HSPN), 31 children with IgA nephropathy aged between 3 to 15 years and 120 children with HSPN aged between 4 to 15 years were compared with each other in clinical manifestation, blood biochemistry, serum immunology and follow-up study. Renal pathological findings under light microscope, immunofluorescence and electronic microscope were analyzed and also compared between 31 children with IgA nephropathy and 32 biopsied children with HSPN. The results showed that the onset age was over 12 years in 25.8% children with IgA nephropathy, but only 10% in HSPN (P < 0.05). The clinical patterns of IgA nephropathy and HSPN were similar, but extra-renal manifestations were more often in HSPN, all of them had skin purpura, 59% had gastrointestinal symptoms and 47% suffered from arthralgia, compared with only abdominal pain in 3.2% children with IgA nephropathy. The renal pathological investigation showed global sclerosis in 35.5% of IgA nephropathy and 3.1% of HSPN, mesangial sclerosis in 41.9% of IgA nephropathy and 6.3% of HSPN, but endothelial proliferation in 65.6% of HSPN and 29% of IgA nephropathy (all P < 0.01). Thin basement membrane nephropathy was only found in 6.5% children with IgA nephropathy, no in HSPN. The electronic dense deposits in HSPN were sparse, loose and wildly spread in glomerular mesangium, subendothelial area and even intra basement membrane, but it was dense, lumpy and mostly limited in mesangium and paramesangium in IgA nephropathy. Predominant IgA deposits were found in 81.2% of HSPN, and overwhelming IgG deposits in 12.5% of HSPN with relatively weak IgA deposits, moreover 6.3% of HSPN showed linear IgG deposits in glomerular capillary. Totally 71.9% of HSPN had IgG deposits in glomeruli and only 19.4% of IgA nephropathy showed glomerular IgG deposits (P < 0.01). No IgG deposit was observed in 81.6% of IgA nephropathy, among them most showed IgA and IgM and/or C3 deposits, moreover overwhelming IgG deposits and linear IgG deposits couldn't be found in IgA nephropathy. Mean 20 months follow-up showed complete remission in 72.5% of HSPN, but only 19.4% in IgA nephropathy after 34 months follow-up. Moreover, 64.5% of IgA nephropathy had consistent hematuria and proteinuria and 16.1% had active nephritides (P < 0.05). It was concluded that significant clinico-pathological difference was found between HSPN and IgA nephropathy, which didn't support the one disease entity hypothesis. HSPN and IgA nephropathy are probably two diseases with similar immune abnormalities. 相似文献

Summary In order to characterize their relationship through clinicopathological comparison between IgA nephropathy and Henoch-Sch?nlein
purpura nephritis (HSPN), 31 children with IgA nephropathy aged between 3 to 15 years and 120 children with HSPN aged between
4 to 15 years were compared with each other in clinical manifestation, blood biochemistry, serum immunology and followup study.
Renal pathological findings under light microscope, immunofluorescence and electronic microscope were analyzed and also compared
