造血干细胞移植后慢性移植物抗宿主病相关的膜性肾病一例

目的 总结造血干细胞移植后慢性移植物抗宿主病（cGVHD）相关的膜性肾病的诊疗体会。方法 为1例急性淋巴细胞白血病患者施行HLA全相合的无关供者外周血造血干细胞移植，术后应用甲氨喋呤和他克莫司（FK506）预防GVHD。术后第19d发生急性GVHD，经甲泼尼龙治疗逆转。分别于术后182d、235d停用FK506和泼尼松，5d后患者出现cGVHD表现，肝功能异常，并伴肾病综合征的相关表现，病理诊断为膜性肾病Ⅱ期，遂给予FK506和泼尼松治疗，同时辅以利尿、降脂等措施。结果发生膜性肾病时，患者的尿蛋白＋＋＋＋，白细胞75个／μl，上皮细胞359．5个／pl，病理性管型＋，管型计数为167个／μl，24h尿蛋白定量为4．28g；肾组织活检，无肾小球硬化，肾小球体积稍大，部分血管袢受压，开放欠佳，肾小球基底膜轻微增厚，外观呈僵硬感，系膜基质轻、中度增殖；间质区部分肾小管扩张，肿胀、变性，未见明显间质纤维化和炎症细胞浸润；Masson染色可见基底膜上皮侧嗜复红物沉积；免疫荧光检查，IgG＋＋＋，C3＋＋＋，IgA＋＋，沿毛细血管袢呈颗粒状节段性分布，系膜区呈团块状分布；IgM、Clq、CA均阴性。电镜下可见肾小球基底膜上皮下沉积物，并有基膜增厚，毛细血管系膜基质轻度增生。经泼尼松和FK506治疗，2个月后尿蛋白转阴。结论 造血干细胞移植后出现肾病综合征或蛋白尿，应考虑GVHD相关膜性肾病的可能，肾穿刺活检有助于诊断，糖皮质激素和FK506治疗有效。

Pattern of renal dysfunction in analgesic nephropathy--comparison with glomerulonephritis.

Comprehensive renal function tests were performed in 84 patients with analgesic nephropathy, 33 glomerulonephritis patients matched for creatinine clearance, and 30 control subjects. A system of 1-day renal function tests including urine microscopy, creatinine clearance, phenolsulphonphthalein excretion, urine concentration and acidification, and electrolyte excretion, was used. Patients with analgesic nephropathy were found to have significant sterile pyuria and haematuria, even those with mild renal insufficiency, significantly reduced concentrating ability and a distal acidifying defect, and a tendency to impaired sodium conservation. These function defects are consistent with the primary lesion of renal papillary necrosis in analgesic nephropathy; the detection of these defects have implications in patient management.     

Rheumatoid arthritis and membranoproliferative glomerulonephritis: an unusual case

SUMMARY: Renal involvement is not uncommon in rheumatoid arthritis (RA). Many RA patients have renal dysfunction either secondary to the drugs used to treat arthritis or because of the chronic inflammation. Renal pathologies have often included amyloidosis, drug-related renal disease and mesangial glomerulonephritis. However, membranoproliferative glomerulonephritis has only been rarely reported. We report a case of rheumatoid arthritis associated with membranoproliferative glomerulonephritis that rapidly progressed to end-stage renal disease.     

Effect of dipyridamole with or without aspirin on urine protein excretion in patients with membranous glomerulonephritis

Summary The antiproteinuric effect of the antiplatelet agent dipyridamole has been assessed after inhibiton of thromboxane B₂ (TxB₂) synthesis in 8 patients with confirmed membranous glomerulonephritis. There were three study periods, each of 30 days, and 45 days apart, namely a washout period, treatment with dipyridamole 300 mg/d, and dipyridamole 225 mg/d plus aspirin 150 mg/d. On Days 1 and 30 of each study period serum and urine creatinine, 24-h excretion of protein, creatinine clearance, platelet aggregometry on whole blood and serum TxB₂ were measured. Treatment with dipyridamole alone or with aspirin produced significant inhibition of platelet aggregation and a fall in 24-h protein excretion; the latter amounted to 54% with dipyridamole alone and 56 % with dipyridamole plus aspirin (NS). Dipyridamole plus aspirin caused an 82 % reduction in serum TxB₂.     

羊踯躅根治疗慢性肾小球肾炎的实验及临床研究

本文用反复静脉注射小剂量牛血清白蛋白复制家兔慢性肾炎,用羊踯躅根治疗。同时,用该药对慢性肾炎病人进行疗效观察。阳性组兔肾小球呈现中至重度颗粒形免疫荧光,肾组织呈明显慢性硬化性肾小球肾炎改变。尿蛋白±～++。治疗组兔及病人治疗后病变及症状均明显减轻或消失。结果提示循环免疫复合物反复沉着可引起兔类似人类的慢性硬化性肾小球肾炎,羊踯躅根对病变有一定的控制和治疗作用,这可能与其抑制免疫发病机制有关。     

Terminal complement complexes in acute poststreptococcal glomerulonephritis

Activation of the complement cascade occurs in most cases of acute poststreptococcal glomerulonephritis (APSGN) and results in the formation of the terminal complement complexes (TCC). To examine the possible role of TCC in the pathogenesis of glomerular injury in APSGN, we studied 30 patients with the clinical diagnosis of APSGN. All patients had an elevated plasma SC5b-9 concentration at the onset of clinical nephritis. Serial plasma concentrations showed an inverse linear relationship with time after onset of clinical disease (r=–0.59,P=0.0008), while plasma C3 concentrations showed a positive linear relationship (r=0.78,P=0.0001). Renal biopsies of 5 patients demonstrated co-localization of C5b-9, S-protein, and C3 deposition in a glomerular capillary loop and mesangial distribution. Urinary excretion of TCC in the acute phase of APSGN was not elevated and was not a useful marker of disease activity. These data suggest that in APSGN with terminal complement pathway activation the local generation of TCC may contribute to the pathogenesis of the disease.

Changing perspectives in children hospitalized with poststreptococcal acute glomerulonephritis

Changing perspectives in 95 children with poststreptococcal acute glomerulonephritis (PSAGN) in our hospital between 1979 and 1988 are reported. Between 1961 and 1970 an average of 31±6.3 patients/year with PSAGN were treated and 70% had antecedent pyoderma. In the present study antecedent pharyngitis was observed in 59 children und pyoderma in 36. In comparison to the decade ending in 1970 our data show: (1) a marked decline in the prevalence of PSAGN (P=<0.0005), (2) a predominance of antecedent pharyngeal infection (P=0.044), (3) a decline in urban and an increase in rural patients with PSAGN (P=0.0483); and in the last decade: (1) a predominance of antecedent pharyngeal infection in children over 6 years of age (P=0.0009) and (2) a predominance of antecedent pyoderma in black children (P=0.0004).
