چکیده
A 58-year-old man with a 15-year history of idiopathic pulmonary fibrosis was hospitalized for rapid progression of muscle weakness to bilateral foot drop. Although laboratory data revealed high titers of myeloperoxidase anti-neutrophil cytoplasmic antibody (489 EU), the patient was diagnosed as polyarteritis nodosa limited to the lower portions of the legs. Despite of the treatment with large doses of corticosteroids and cyclosporin A, his symptoms barely improved during the following two months.

Antineutrophil cytoplasmic antibody-positive conversion and microscopic polyangiitis development in patients with idiopathic pulmonary fibrosis
BACKGROUND Increasing evidence indicates that antineutrophil cytoplasmic antibody (ANCA)-positive conversion occurs in patients initially diagnosed with idiopathic pulmonary fibrosis (IPF) and as a result, some of these patients develop microscopic polyangiitis (MPA). However, the incidence density of these patients is not well known. OBJECTIVES To explore the incidence of ANCA-positive conve...

The association between interstitial lung disease (ILD) and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), particularly microscopic polyangiitis (MPA), has been described in a number of case reports and case series reports in the last 2 decades. In addition, patients with pulmonary fibrosis and ANCA positivity but without other manifestations of systemic vasculitis hav...

Antineutrophil cytoplasmic autoantibodies (ANCA) were detected in patients with autoimmune and vascular diseases such as Wegener's granulomatosis, polyarteritis nodosa and systemic lupus erythematosus. Indirect immunofluorescence (IIF) technique was employed to detect these autoantibodies. By this method, two general patterns of ANCA were seen: a cytoplasmic (cANCA) and a perinuclear form ...
متن کاملPolyarteritis Nodosa
Polyarteritis nodosa (PAN) is the systemic necrotizing vasculitis on small and median muscular vessels. Recent studies reveal that PAN consists of classical PAN and microscopic polyangitis (MPA). MPO-ANCA, which is one of anti-neutrophil cytoplasmic antibody (ANCA), is involved in the pathogenesis of MPA. In future, by the progress of research of ANCA, the definition or criteria of systemic vas...
