A kidney biopsy is valuable in establishing a diagnosis and prognosis for end-stage renal disease in older patients with ANCA-associated vasculitis who have kidney involvement, although they are not useful for predicting overall survival, a study shows. “Prognosis and Histological Classification in Elderly Patients with ANCA-Glomerulonephritis: A Registry-Based…

While rare, patients with scleroderma — a disease that causes skin hardening — can also develop ANCA-associated vasculitis, a case report shows. The study, “Perinuclear Antineutrophil Cytoplasmic Antibody Positive Glomerulonephritis in a Case of Limited Cutaneous Scleroderma,” was published in the Indian Journal of Nephrology.

A deficiency in leptin — the hormone that signals the brain when a person has eaten enough — may lead to the development of ANCA-associated vasculitis (AAV), according to a new case study from India. The report, “ANCA-associated Vasculitis in a Case of Congenital Leptin Deficiency,” was published…

Excessive activation of a defense mechanism of neutrophils — key immune cells in ANCA-associated vasculitis (AAV) — is a potential biomarker for active disease, according to researchers. Their study, “Excessive neutrophil extracellular trap formation in ANCA-associated vasculitis is independent of ANCA,” was published in the journal Kidney…

Patients with granulomatosis with polyangiitis whose autoantibodies are against the myeloperoxidase protein (MPO) have increased disease activity at diagnosis but milder kidney manifestations than other vasculitis patients. Based on findings from a retrospective analysis, a research team in China proposes that these patients should be considered a unique subtype of…

Tracheobronchial stenosis, a lung complication characterized by the narrowing of the trachea and bronchi, is common in patients with granulomatosis with polyangiitis (GPA) and is often the first disease symptom, researchers have found. However, despite its frequent occurrence, there are no standardized treatment protocols for this serious complication. More prospective…
