Antineutrophil cytoplasmic antibodies in myelodysplasia.

Auto-antibodies in Patients with Inflammatory Bowel Disease Unclassified

Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...

Antineutrophil Cytoplasmic Antibodies in Patients with Pulmonary Tuberculosis

Background: Mycobacterium tuberculosis is a major cause of mortality and morbidity worldwide. Infection with this bacterium is known to induce the development of autoantibodies of which a few are also known to be diagnostic markers for some other diseases. Antineutrophil Cytoplasmic Antibodies (ANCA's) are among those autoantibodies used in clinical setting for diagnosing systemic vasculitic sy...

ANTINEUTROPHIL CYTOPLASMIC AUTOANTIBODI ES IN RHEUMATOID ARTHRITIS

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 ...

Predictive value of antineutrophil cytoplasmic antibodies in small-vessel

Familial clusters of ANCA small-vessel vasculitis

Small-vessel vasculitides associated with the presence of antineutrophil cytoplasmic antibodies in the serum are characterized by inflammation and necrosis of small vessels. A pauci-immune necrotizing crescentic glomerulonephritis typically occurs when there is renal damage. Pathogenesis of these diseases remains unclear although infectious, genetic and environmental factors have been involved....
