Aim: To report a case of a patient with myeloperoxidase-antineutrophil cytoplasmic antibody (ANCA)-negative microscopic polyangiitis (MPA) and IgA nephropathy associated with severe pulmonary haemorrhage.
Case Report: A 59-year-old man presented with ANCA-negative systemic vasculitis accompanied by purpura, nephritis and pulmonary haemorrhage. A skin biopsy specimen revealed pandermal leucocytoclastic vasculitis without IgA deposition and a kidney biopsy showed mesangial nephritis with IgA deposition. Considering these findings, the patient was diagnosed as having MPA with IgA nephropathy.
Discussion: In most cases, MPA presents with rapidly progressive necrotizing glomerulonephritis and sometimes lung haemorrhage, while IgA nephropathy is less common among MPA cases. As recent research suggested that in MPA immunoglobulin deposition in the kidney may be an exacerbating factor for renal dysfunction and poor prognosis, close observation is required in these cases.

Phospholipase A2 receptor 1 (PLA2R1) exists in many animals and plays an important role in membranous nephropathy. In this study, we aimed to evaluate a PLA2R1 knock-in rat model with repaired kidney function to study the molecular mechanisms of membranous nephropathy. We constructed the PLA2R1 knockout [PLA2R1(-)] model and PLA2R1 knock in [PLA2R1(+)] model in rats.

Introduction: Endothelin A (ETA) receptor activation is a driver of proteinuria, kidney inflammation, and fibrosis in IgA nephropathy (IgAN). Atrasentan, a selective ETA receptor antagonist, has potential to reduce proteinuria and preserve kidney function in IgAN. ALIGN (NCT04573478) is a phase 3, randomized, double-blind, placebo-controlled clinical trial of atrasentan in patients with IgAN at high risk of kidney function loss.

Background: The factors influencing diffuse crescentic glomerulonephritis renal survival and prognosis remain uncertain. Additionally, there's no literature on the clinical outcomes of IgA nephropathy, lupus nephritis, and IgA vasculitis nephritis in type II patients.
Methods: This study retrospectively examined 107 patients diagnosed with diffuse crescentic glomerulonephritis through biopsy.
This article provides an overview of treatment approaches for chronic kidney disease (CKD) in patients with IgA nephropathy (IgAN). IgAN is the most common primary glomerulonephritis and results from an autoimmune reaction to aberrantly glycosylated immunoglobulin A (IgA) antibodies. Although historically considered largely benign, it is now recognized that a significant percentage of patients develop dialysis-dependent kidney disease over the years.

Nephrotic syndrome (NS) occurs in 5-15% of patients with IgA nephropathy (IgAN), resulting in poorer long-term outcomes compared to those without NS. Clinical features and renal prognosis for patients with both NS and IgAN across different kidney pathologies have not been fully elucidated. This study included patients with primary IgAN through renal biopsy at the First Affiliated Hospital of Sun Yat-sen University from January 2001 to November 2021 presenting with NS.
