Details


Specifically, ANCA have been found (at frequencies ranging from 70% to 90%) in patients with active Wegener granulomatosis, microscopic polyarteritis nodosa, and idiopathic crescentic glomerulonephritis (with manifestations ranging from kidney-limited disease to extrarenal systemic disease, including pulmonary-renal syndromes). Glomerular lesions in patients with ANCA-associated systemic vasculitis or renal-limited disease are virtually identical. Normal controls are negative for ANCA and <10% of patients with other renal diseases are positive. ANCA may be directly involved in the pathogenesis of the vascular injury that causes the clinical manifestations in ANCA-associated disease. 


Antineutrophil cytoplasmic autoantibodies exhibiting pANCA or cANCA patterns are detected using indirect immunofluorescent antibody (IFA) techniques with a substrate of ethanol-fixed human neutrophils. Positive patient sera with perinuclear or nuclear patterns are repeated using a formalin-fixed substrate in order to differentiate the presence of true pANCA antibodies from possible interference with antinuclear antibodies (ANA).
