BACKGROUND Proteinuria varies in different glomerular diseases and even the same one. Podocin, encoded by gene NPHS2, is important in maintaining the integrity of slit diaphragm structure and avoiding proteinuria. Presently, case-control association studies were performed to investigate the genetic effect of variants in NPHS2 in a mass proteinuric(More)
Increasing evidence points to the importance of aberrant O-glycosylated immunoglobulin A1 (IgA1) in the pathogenesis of IgA nephropathy (IgAN), a disease widely considered to be a polygenic disorder. We earlier found that haplotypes in two key glycosyltransferase genes, C1GALT1 and ST6GALNAC2, were associated with susceptibility to IgAN. Here we measured(More)
BACKGROUND KDIGO (Kidney Disease: Improving Global Outcomes) guidelines recommend that a lateral abdominal radiograph should be performed to assess vascular calcification (VC) in dialysis patients. However, abdominal aortic calcification is a prevalent finding, and it remains unclear whether other anatomical areas of VC can predict mortality more(More)
Introduction Lateral abdominal radiograph is suggested as an alternative to coronary artery computed tomography (CT) in evaluating vascular calcification. Simple scoring systems including pelvic radiograph scoring and abdominal scoring system were utilized to study their correlation with coronary artery calcification. Methods In 106 MHD patients, coronary(More)
IgA nephropathy (IgAN) is a polygenic disorder. Increasing evidence has implicated that aberrant glycosylation of IgA1 molecules, including alpha2,6 sialic acid defects, are involved in the pathogenesis of IgAN. In the present study, we designed an association study to investigate polymorphisms of two important genes, ST6GALNAC2 and NEU1, which are involved(More)
BACKGROUND The Wenchuan Earthquake resulted in calamitous destruction and massive death. We report the characteristics of crush syndrome (CS) and acute kidney injury (AKI) brought by the earthquake, which took place in a mountainous area. METHODS We conducted a cross-section survey of total 2,316 consecutive admissions because of seismic trauma, of which(More)
MUC20, an upregulated novel gene in the renal tissues of patients with IgA nephropathy (IgAN), was recently identified. The variable number of tandem repeats (VNTR) polymorphism of the MUC20 gene was detected in several cell lines. In the present study, we investigated a possible association of MUC20 VNTR polymorphism with the clinical manifestations and(More)
BACKGROUND Malnutrition and inflammation are common and serious complications in patients with acute kidney injury (AKI). However, the profile of these complications in patients with AKI caused by crush syndrome (CS) remains unclear. This study describes the clinical characteristics of malnutrition and inflammation in patients with AKI and CS due to the(More)
AIM Meta-analysis of data from a genome-wide association study (GWAS) identified seven single nucleotide polymorphisms (SNPs) as strong predictors of IgA nephropathy (IgAN). To replicate the association of these seven SNPs and understand whether they influence the clinical characteristics of IgAN, a case-control study including 521 IgAN patients and 535(More)
