Treating primary membranous nephropathy with extremely high titer of anti-phospholipase A2 receptor antibodies: A case of failed treatment with very high-dose rituximab.

Rituximab (RTX) is the anti-CD20 monoclonal antibody that has been used as the first-line therapy for primary membranous nephropathy (PMN) in recent years. However, the optimal dosing regimen and timing of RTX, or combination with other immunosuppressants, especially in patients with extremely high titers (> 1,000 RU/mL) of anti-PLA2R antibody (aPLA2R), are unclear at present. This report describes the case of a 70-year-old PMN patient with extremely high aPLA2R titer who failed to respond to very high doses of RTX.

Dapagliflozin improves podocytes injury in diabetic nephropathy via regulating cholesterol balance through KLF5 targeting the ABCA1 signalling pathway.

Diabetic nephropathy (DN), one of the more prevalent microvascular complications in patients diagnosed with diabetes mellitus, is attributed as the main cause of end-stage renal disease (ESRD). Lipotoxicity in podocytes caused by hyperglycemia has been recognised as a significant pathology change, resulting in the deterioration of the glomerular filtration barrier. Research has demonstrated how dapagliflozin, a kind of SGLT2i, exhibits a multifaceted and powerful protective effect in DN, entirely independent of the hypoglycemic effect, with the specific mechanism verified.

GDF-15 alleviates diabetic nephropathy via inhibiting NEDD4L-mediated IKK/NF-κB signalling pathways.

Podocyte inflammatory injury has been indicated to play a pivotal role in the occurrence and development of diabetic nephropathy (DN). However, the pathogenesis of inflammation remains unclear. Recent researches have shown that GDF-15, a member of the transforming growth factor-β superfamily, were elevated under pathological conditions, such as myocardial ischemia, cancer, as well as inflammation.

Inhibition of EZH2 mitigates peritoneal fibrosis and lipid precipitation in peritoneal mesothelial cells mediated by klotho.

Background: Peritoneal fibrosis caused by long-term peritoneal dialysis (PD) is the main reason why patients withdraw from PD treatment. Lipid accumulation in the peritoneum was shown to participate in fibrosis, and klotho is a molecule involved in lipid metabolism. GSK343 (enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) inhibitor) has been verified to inhibit epithelial mesenchymal transdifferentiation (EMT) and peritoneal fibrosis, but its related mechanism remains unclear.

Recurrent peritonitis relapse in a patient with atrial septal defect undergoing peritoneal dialysis: a case report.

Background: Peritonitis is the most common complication in patients undergoing peritoneal dialysis (PD). Most patients recover with appropriate antibiotic treatment; however, when peritonitis repeatedly relapses, the cause of recurrence must be explored. The relationship between atrial septal defect (ASD), infective endocarditis (IE), and peritonitis is rarely reported.

Faster lipid β-oxidation rate by acetyl-CoA carboxylase 2 inhibition alleviates high-glucose-induced insulin resistance via SIRT1/PGC-1α in human podocytes.

Diabetic nephropathy (DN) is becoming a research hotspot in recent years because the prevalence is high and the prognosis is poor. Lipid accumulation in podocytes induced by hyperglycemia has been shown to be a driving mechanism underlying the development of DN. However, the mechanism of lipotoxicity remains unclear.

Associations between the concentrations of CD68, TGF-β1, renal injury index and prognosis in glomerular diseases.

The present study aimed to investigate the association between the concentrations of CD68, TGF-β1, renal injury index and prognosis in glomerular diseases. Altogether 218 patients with glomerular diseases admitted to Weifang People's Hospital from January, 2014 to March, 2017 were used as the study group. A total of 100 healthy individuals who visited Weifang People's Hospital for a physical examination during the same time period were used as the control group.
