MP157SYSTEMIC SMALL VESSEL VASCULITIS ASSOCIATED WITH ANTINEUTROPHIL CYTOPLASMIC ANTIBODIES-OWN EXPERIENCE

Predictive value of antineutrophil cytoplasmic antibodies in small-vessel vasculitis.

OBJECTIVE . The predictive value of antineutrophil cytoplasmic antibodies (ANCA) as markers of clinical activity of small vessel vasculitis is controversial. We reviewed the outcome of patients with ANCA-associated vasculitis from a single center and evaluated the predictive value of ANCA as markers of relapse. METHODS The medical history of all consecutive patients with ANCA-associated vascu...

Monitoring proteinase 3 antineutrophil cytoplasmic antibodies for detection of relapses in small vessel vasculitis.

The clinical usefulness of antineutrophil cytoplasmic antibodies (ANCAs) in the monitoring of patients treated for small vessel vasculitis is debated. A capture enzyme-linked immunosorbent assay (ELISA) based on anti-proteinase 3 (anti-PR3) monoclonal antibody 4A3 has previously been proven to be superior to indirect immunofluorescence (IIF) and standard ELISA for the diagnosis of vasculitis. T...

Pulmonary Fibrosis in Antineutrophil Cytoplasmic Antibodies (ANCA)-Associated Vasculitis

Pulmonary fibrosis (PF) is an uncommon manifestation observed in patients with antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), particularly microscopic polyangiitis (MPA). While patients with PF associated with AAV seem to e Brun, MD, Philip D, avid Saadoun, MD, PhD patients with PF associated with AAV, fulfilling the American College of Rheumatology criteria and/or Ch...

Refractory disease in antineutrophil cytoplasmic antibodies associated vasculitis.

PURPOSE OF REVIEW Induction treatment of antineutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) is not always successful and nonresponding patients are considered refractory. RECENT FINDINGS Refractory disease should be subdefined to the treatment that was received. Cyclophosphamide refractory AAV occurs in up to 5% of patients. Many more patients develop contraindications t...
