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...
متن کاملMyeloperoxidase-Antineutrophil Cytoplasmic Antibody-Negative Microscopic Polyangiitis with Pulmonary Haemorrhage and IgA Nephropathy
AIM To report a case of a patient with myeloperoxidase-antineutrophil cytoplasmic antibody (ANCA)-negative microscopic polyangiitis (MPA) and IgA nephropathy associated with severe pulmonary haemorrhage. CASE REPORT A 59-year-old man presented with ANCA-negative systemic vasculitis accompanied by purpura, nephritis and pulmonary haemorrhage. A skin biopsy specimen revealed pandermal leucocyto...
متن کاملAntineutrophil 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...
متن کاملAntineutrophil cytoplasmic antibody associated microscopic polyangiitis and sinobronchial syndrome.
Antineutrophil cytoplasmic antibodies (ANCA)are well known to be associated with small sized vessel vasculitic diseases such as microscopic polyangiitis (MPA), allergic granulomatous angiitis (AGA), and Wegener's granulomatosis (WG) (1). One subtype is an antibody against myeloperoxidase (MPO), which stains in a perinuclear pattern (P ANCA)by indirect immunofluorescence (IIF) using a neutrophil...
