In this study, we investigated the efficacy of oxymatrine, a phytochemical alkaloid, in reducing inflammation and fibrosis in a rat model of IgA nephropathy (IgAN) through modulation of the TGF-β/SMAD signaling pathway. Thirty Sprague Dawley rats were randomized into control, IgAN, and treatment groups, the latter receiving oxymatrine postinduction of IgAN. Induced by bovine serum albumin, carbon tetrachloride, and lipopolysaccharides, the disease model was validated by immunofluorescence and histopathological analyses, confirming significant renal deposition of IgA and increased fibrosis markers (IL-6, TGF-β, SMAD 3, and α-SMA).

Immunoglobulin A nephropathy (IgAN) is the most prevalent form of primary glomerulonephritis globally, yet its pathogenesis remains incompletely understood. While much research has focused on the gut microbiome in the development of the disease, emerging evidence suggests that the oropharyngeal microbiota may also be a potential contributor. Studies have revealed significant alterations in oropharyngeal microbial diversity and specific bacterial taxa in IgAN patients, correlating with disease severity and progression.

Article Synopsis
  • - A 27-year-old female with a decade-long history of Crohn's disease was diagnosed with both Fabry disease (FD) and IgA nephropathy (IgAN) after presenting with kidney issues, including microscopic hematuria and proteinuria.
  • - Kidney biopsy results showed characteristics of IgAN, such as mesangial matrix widening, and electron microscopy revealed findings consistent with both IgAN and FD.
  • - The diagnosis of FD was confirmed by low enzyme activity, leading to the start of enzyme replacement therapy; this case is notable as the first documented occurrence of FD, IgAN, and Crohn's disease coexisting in one patient.

Endothelin receptor antagonists in chronic kidney disease.

Nat Rev Nephrol

December 2024

Department of Clinical Pharmacy and Pharmacology, University Medical Center Groningen, University of Groningen, Groningen, the Netherlands.

Endothelin-1 is a potent vasoconstrictor that has diverse physiological functions in the kidney, including in the regulation of blood flow and glomerular filtration, electrolyte homeostasis and endothelial function. Overexpression of endothelin-1 contributes to the pathophysiology of both diabetic and non-diabetic chronic kidney disease (CKD). Selective endothelin receptor antagonists (ERAs) that target the endothelin A (ET) receptor have demonstrated benefits in animal models of kidney disease and in clinical trials.

The billing database of the universal healthcare system in Japan potentially includes large-cohort data of patients with immunoglobulin A nephropathy, diagnosis codes aimed at billing should not be directly used for clinical research because of the risk of misdiagnosis. To solve this problem, we aimed to develop a novel method for identifying patients with immunoglobulin A nephropathy from billing data using machine learning. The medical records and bills of 3,743 patients who consulted nephrologists at a single center were extracted.
