Mesangial IgM deposition predicts renal outcome in patients with IgA nephropathy: a multicenter, observational study.

Mesangial IgM deposition is found in patients with immunoglobulin A nephropathy (IgAN). This study aims to investigate the relationships between mesangial IgM deposition and disease progression in IgAN patients. A total of 1239 patients with biopsy-proven primary IgAN were enrolled in this multicenter, observational study between January 2013 and August 2017.

Modifications of gut microbiota are associated with the severity of IgA nephropathy in the Chinese population.

Immunoglobulin A nephropathy (IgAN) is a common glomerular disease. The pathogenesis of IgAN is associated with dysregulated intestinal mucosal immunity. However, whether gut microbial modifications play a role in IgAN remains unclear.

Goodpasture syndrome manifesting as nephrotic-range proteinuria with anti-glomerular basement membrane antibody seronegativity: A case report.

Rationale: The Goodpasture syndrome is an extremely rare disease, with renal and pulmonary manifestations, and is mediated by anti-glomerular basement membrane (anti-GBM) antibodies. Renal pathological changes are mainly characterized by glomerular crescent formation and linear immunofluorescent staining for immunoglobulin G on the GBM. There are few reports on the atypical course of the syndrome involving serum-negative anti-GBM antibodies.

Corticosteroids could improve the renal outcome of IgA nephropathy with moderate proteinuria.

Background: The specific treatment regimens of IgA nephropathy (IgAN) patients with moderate proteinuria (1.0-3.5 g/day) remain controversial.

Crescent lesions are not a predictive factor in adult-onset Henoch-Schönlein purpura nephritis.

Henoch-Schönlein purpura nephritis (HSPN) is a common secondary glomerulonephritis, and its prognosis mainly depends on the severity of renal impairment. To date, the significance of crescent lesions in adult-onset HSPN is still unclear. Therefore, the purpose of this research was to assess whether crescents could predict the renal outcomes in adult HSPN patients.
