Sometimes ANCA vasculitis can affect kidney function slowly- over weeks, months, or even years- but in many people, it can happen very quickly, in days. The inflammation leads to scarring, or permanent damage to the kidney.

Kidney involvement is very common in ANCA associated vasculitis. Diagnosis of kidney involvement is made from blood tests, urine tests and often a kidney biopsy. Treatment usually involves high dose steroids combined with immunosuppressive medications such as cyclophosphamide or rituximab.

The kidney is the most commonly affected vital organ in ANCA-associated vasculitis, and patient outcomes are largely determined by the severity of renal disease at diagnosis and by its response to treatment.

Kidney involvement in ANCA-associated vasculitis is frequent and the most common predictor of mortality. Patients with estimated glomerular filtration rate (eGFR) <50 mL/min have a 50% risk of death or kidney failure within 5 years of diagnosis.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of pauci-immune small vessel vasculitides that often affect the kidneys manifesting as rapidly progressive glomerulonephritis.

Patients with systemic ANCA-associated vasculitis, pulse cyclophosphamide versus continuous cyclophosphamide Table S10. Patients with ANCA-associated vasculitis and severe kidney disease, reduced-dose oral glucocorticoid versus standard-dose oral glucocorticoid Table S11.

2024年8月22日 · In The Lancet Rheumatology, Karl Gisslander and colleagues present a cluster analysis using real-world data, identifying five distinct phenotypic clusters among patients with ANCA-associated vasculitis. 5 Of particular interest are three clusters characterised by substantial kidney involvement: the severe kidney cluster (SK), the ...

2019年7月26日 · Serologic classification of AAV into proteinase 3–ANCA disease and myeloperoxidase-ANCA disease correlates with a number of disease characteristics. AAV has a predilection for the kidney, with >75% of patients having renal involvement characterized by rapidly progressive glomerulonephritis.

ANCA are serum autoantibodies directed against proteins present in the cytoplasmic granules of neutrophils and represent the serological markers of small vessel vasculitis.

2024年8月31日 · Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitides are a heterogeneous group of rare autoimmune conditions that cause inflammation of blood vessels with various manifestations. The 3 main ANCA–associated vasculitides are granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis.
