Aortitis syndrome associated with positive perinuclear antineutrophil cytoplasmic antibody: report of three cases

Int J Cardiol. 2000 Aug 31;75 Suppl 1:S89-94; discussion S95-7. doi: 10.1016/s0167-5273(00)00176-5.

Abstract

We recently experienced three cases of aortitis syndrome that were associated with perinuclear antineutrophil cytoplasmic antibody (ANCA). In the three cases, roentgenographic examination revealed the typical appearance of stenosis or occlusive subclavian arteries. In addition, two cases showed a thickened thoracic aorta wall and the remaining case had irregular stenosis of both common iliac arteries. All three cases had persistently increased ESR and CRP over the years. These findings suggested the diagnosis of aortitis syndrome. ANCA tests were performed because of rapidly progressive glomerulonephritis symptoms in two patients and marked excretion of beta(2)-microglobulin in urine in one patient. The test showed P-ANCA in all three patients, with two patients identified as anti-MPO antibody and the third patient as non-MPO antibody. The implication of ANCA in the pathogenesis of aortitis syndrome is presumed to be: ANCA, which plays an important role in the pathogenesis of small vessel vasculitis, induces vasculitis of the vasa vasorum in the aorta or main branches (or both) and this pathologic process results in the pathogenesis of aortitis syndrome.
