A new report from researchers at the First Affiliated Hospital of Guangxi Medical University in China explores the use of urinary N-acetyl-b-D-glucosaminidase (uNAG) and serum homocysteine (sHCY) as potential predictors for the early detection and prognosis of contrast-induced nephropathy (CIN) in patients after percutaneous coronary intervention (PCI). The study found that the combination of uNAG and sHCY demonstrated better sensitivity and specificity for predicting the diagnosis and prognosis of CIN compared to using either biomarker alone. The panel of uNAG and sHCY also detected CIN earlier than serum creatinine (sCr). However, the combined detection did not significantly enhance the predictive capability for major adverse cardiovascular events (MACE) in patients with CIN. [Extracted from the article]

A recent study conducted by researchers at Thomas Jefferson University Sidney Kimmel Medical College provides new insights into IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide. The study highlights the pathogenesis of IgAN, which involves the activation and proliferation of mesangial cells, inflammatory cell recruitment, complement activation, and podocyte damage. Diagnosis of IgAN requires a biopsy interpreted by the Oxford criteria, and biomarkers such as proteinuria, reduced GFR, hypertension, and pathology can predict adverse outcomes. The mainstay of therapy for IgAN is supportive care, including lifestyle modifications and medication interventions. Immunosuppression may be considered for high-risk patients, but the use of corticosteroids and other immunosuppressants carries a high risk of side effects. Ongoing research is focused on B-cell inhibition and complement inhibition as potential treatment strategies. [Extracted from the article]

A recent study conducted by researchers at Juntendo University Faculty of Medicine in Tokyo, Japan, has shed light on the pathogenesis of IgA nephropathy (IgAN), the most common form of glomerulonephritis (GN) worldwide. The researchers discovered that IgAN is a tissue-specific autoimmune disease, characterized by the deposition of IgA in the glomerular mesangium of the kidneys. They identified two autoantigens, b2-spectrin and CBX3, that are targeted by autoantibodies specific to mesangial cells. The production of these autoantibodies is induced by certain strains of commensal bacteria in the oral cavity. This research provides new insights into the mechanisms underlying IgAN and offers a new perspective on its pathogenesis. [Extracted from the article]

Researchers from Ainshams University in Cairo, Egypt have conducted a study to predict the development of contrast-induced nephropathy (CIN) in patients with chronic total occlusion (CTO) after percutaneous coronary intervention (PCI).

A preprint abstract discusses a study on the unique susceptibility of the human kidney to pH dysfunction and injury in cystinosis, a lysosomal storage disease. The study involved profiling renal proximal tubular epithelial cells (RPTECs) and fibroblasts isolated from patients with cystinosis. The researchers found that loss of cystinosin in RPTECs led to a reduction in ATP6V0A1 expression, resulting in changes in intracellular pH, mitochondrial integrity, mitochondrial function, and autophagosome-lysosome clearance. The study suggests a novel mechanism of tubular injury in cystinosis and calls for further research in animal models to explore its potential clinical applications. [Extracted from the article]

A recent study conducted at Kowsar Hospital in Shiraz, Iran, explored the association between different patterns of immunofluorescence deposits in IgA nephropathy (IgAN) patients and various clinical and morphological parameters. The study found that certain morphological parameters, such as endocapillary hypercellularity and tubular atrophy/interstitial fibrosis, were independent risk factors for mesangiocapillary deposits of IgA. Additionally, the presence of IgG deposition and the total MEST score were also identified as risk factors. The research suggests that hyperactivation of immunoglobulins and the complement system may contribute to mesangial-capillary proliferation in IgAN. [Extracted from the article]

This case report suggests that telitacicept may be an effective and safe treatment option for women with IgAN who wish to conceive. [Extracted from the article]

A recent study conducted by researchers at Mashhad University of Medical Sciences in Iran examined the correlation between the MEST-C score in kidney biopsies of patients with IgA nephropathy (IgAN) and their prognosis. IgAN is the most common type of primary glomerulonephritis and can lead to end-stage renal disease (ESRD). The study found that the urinary protein level at diagnosis and the T-score on biopsy were significant prognostic factors, while other pathological factors did not show significance. However, further research is needed to validate the MEST-C scoring system in different populations before it can be used in routine clinical practice. [Extracted from the article]

A recent study conducted at Tianjin Medical University in China explored the levels of IgA binding and sialylation profiles of IgG in IgA nephropathy (IgAN), a kidney disorder characterized by the deposition of immune complexes in the glomeruli.
