<prompt> Which of the following conditions are associated with raised ANCA exceptWegeners granulomatosisPolyaeritis NodosaMicroscopic PolyangitisChurg-Strauss syndrome  <response>: Many patients with vasculitis have circulating antibodies that react with neutrophil cytoplasmic antigens, so-called anti-neutrophil cytoplasmic antibodies ANCAs. ANCAs are a heterogeneous group of autoantibodies directed against constituents mainly enzymes of neutrophil primary granules, monocyte lysosomes, and endothelial cells. ANCAs are very useful diagnostic markers; their titers generally mirror clinical severity, and a rise in titers after periods of quiescence is predictive of disease recurrence. PR3-ANCAs are associated with Wegener granulomatosis. MPO-ANCAs are associated with microscopic polyangiitis and Churg-Strauss syndrome. Robbins Basic Pathology,9th edition,pg no.350
