目的 :观察前列腺素E1脂微球载体制剂 (Lipo PGE1)对原发性肾病综合征局灶节段性肾小球硬化 (FS GS)患者血管内皮生长因子 (VEGF)生成的影响。方法 :39例肾活检确诊为FSGS患者随机分为治疗组 2 0例 ,未治疗组 19例 ,另选性别、年龄相匹配的健康查体者 2 0例作为对照组。治疗组用Lipo PGE110 μg ,未治疗组用ATP 2 0mg ,两组药物均溶于 10 0ml生理盐水中静脉滴注 ,1次 /d ,2周为 1疗程。 1疗程完成后采用ELISA方法测定三组血、尿VEGF水平 ,同时测定三组内生肌酐清除率和 2 4h尿蛋白定量。结果 :FSGS组血、尿VEGF及 2 4h尿蛋白定量与对照组相比明显增高 ,内生肌酐清除率较低 ;治疗组血、尿VEGF浓度显著下降 ,2 4h尿蛋白定量明显降低 ,内生肌酐清除率上升。两两比较P <0 .0 5 ,差异有统计学意义。结论 :Lipo PGE1治疗FSGS可以有效减轻蛋白尿 ,改善肾功能 ,对早期防治慢性肾衰竭有重要意义 ,VEGF的表达生成与治疗作用有一定的关系。 相似文献

Vinai M, Waber P, Seikaly MG. Recurrence of focal segmental glomerulosclerosis in renal allograft: An in‐depth review.Pediatr Transplantation 2010: 14: 314–325. © 2010 John Wiley & Sons A/S. Abstract: Focal segmental glomerulosclerosis is a major cause of chronic kidney disease requiring transplantation in children. Recurrence rate in the renal allograft transplantation is as high as 50%. Recurrence of FSGS is associated with renal dysfunction and early graft loss. To date, there is no established therapy for recurrent FSGS after renal transplant. We have reviewed the current English literature in order to summarize current practices with emphasis on graft outcome. We conclude that despite multiple approaches to the post transplant management of recurrent FSGS, none have been shown to be consistently beneficial. Currently, pheresis combined with high dose anti‐calcineurin with or without rituximab seems to be the most promising. Further controlled studies are needed to define the optimal therapeutic regimens to treat recurrent of FSGS. 相似文献

Apolipoprotein L1 gene (APOL1) G1 and G2 variants are strongly associated with progressive nondiabetic nephropathy in populations with recent African ancestry. Selection for these variants occurred as a result of protection from human African trypanosomiasis (HAT). Resequencing of this region in 10 genetically and geographically distinct African populations residing in HAT endemic regions identified eight single nucleotide polymorphisms (SNPs) in strong linkage disequilibrium and comprising a novel G3 haplotype. To determine whether the APOL1 G3 haplotype was associated with nephropathy, G1, G2, and G3 SNPs and 70 ancestry informative markers spanning the genome were genotyped in 937 African Americans with nondiabetic ESRD, 965 African Americans with type 2 diabetes–associated ESRD, and 1029 non-nephropathy controls. In analyses adjusting for age, sex, APOL1 G1/G2 risk (recessive), and global African ancestry, the G3 haplotype was not significantly associated with ESRD (P=0.05 for nondiabetic ESRD, P=0.57 for diabetes-associated ESRD, and P=0.27 for all-cause ESRD). We conclude that variation in APOL1 G3 makes a nominal, if any, contribution to ESRD in African Americans; G1 and G2 variants explain the vast majority of nondiabetic nephropathy susceptibility. 相似文献

Genetic variants in apolipoprotein L1 (APOL1) confer risk for kidney disease. We sought to better define the phenotype of APOL1-associated nephropathy. The FSGS Clinical Trial involved 138 children and young adults who were randomized to cyclosporin or mycophenolate mofetil plus pulse oral dexamethasone with a primary outcome of proteinuria remission. DNA was available from 94 subjects who were genotyped for APOL1 renal risk variants, with two risk alleles comprising the risk genotype. Two APOL1 risk alleles were present in 27 subjects, of whom four subjects did not self-identify as African American, and 23 of 32 (72%) self-identified African Americans. Individuals with the APOL1 risk genotype tended to present at an older age and had significantly lower baseline eGFR, more segmental glomerulosclerosis and total glomerulosclerosis, and more tubular atrophy/interstitial fibrosis. There were differences in renal histology, particularly more collapsing variants in those with the risk genotype (P=0.02), although this association was confounded by age. APOL1 risk genotype did not affect response to either treatment regimen. Individuals with the risk genotype were more likely to progress to ESRD (P<0.01). In conclusion, APOL1 risk genotypes are common in African-American subjects with primary FSGS and may also be present in individuals who do not self-identify as African American. APOL1 risk status is associated with lower kidney function, more glomerulosclerosis and interstitial fibrosis, and greater propensity to progress to ESRD. The APOL1 risk genotype did not influence proteinuria responses to cyclosporin or mycophenolate mofetil/dexamethasone. 相似文献
