A 61-year-old male with chronic cough, paraesthesia of the extremities, and sinusitis presented for acute worsening symptoms despite initial treatment antibiotics prednisone. Emergency department evaluation revealed mild elevated troponin without ECG changes in absence coronary symptoms, but markedly eosinophil count an abnormal chest CT. nuclear stress test basal inferoseptal dyskinesis fixed ...
Autoantibodies against a constituent of the glomerular basement membrane (GBM), the α3-chain of type IV collagen, can cause both rapidly progressive glomerulonephritis and alveolar hemorrhage, referred to as anti-GBM disease or Goodpasture disease. Anti-GBM antibodies generally are of immunoglobulin G subclass 1 (IgG1) and can in most cases readily be detected in the circulation using enzyme-li...
Systemic vasculitis is a heterogeneous group of disorders characterized by inflammation andnecrosis in the vessel wall. The diagnosis of a systemic vasculitis is challenging, because patients usually present a broad spectrum of manifestations that vary according to the predominant size of vessels affected, organs and systems involved, and the extent of the inflammatory process (1). In systemic ...
Granulopoiesis-related genes are distinctively upregulated in peripheral leukocytes of patients with antineutrophil cytoplasmic autoantibodies (ANCA)-associated glomerulonephritis. Affymetrix microarrays identified the upregulation of nine neutrophilic primary granule genes, including myeloperoxidase (MPO) and proteinase 3 (PR3), plus five secondary granule genes. Coordinate expression of granu...
Proteinase-3 (PR-3) is a neutral serine proteinase present in azurophil granules of human polymorphonuclear leukocytes and serves as the major target antigen of antineutrophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA) in Wegener's granulomatosis (WG). The WG disease appears as severe vasculitis in different organs (e.g. kidney, nose and lung). Little is known about the...
