The testing of anti-neutrophil cytoplasmic antibodies (ANCA) takes an important place in the diagnostic workup to ANCA-associated vasculitis (AAV). Nowadays, it is recommended screen for presence PR3 and MPO specific first using immunoassay, without need ANCA measurement by indirect immunofluorescence (IIF). A literature search was performed assess test value IIF PR3- MPO-antibody immunoassay d...

A monoclonal antibody that recognizes a cell-surface glycoprotein associated with glucose transport was reported previously. Additional information about the function and intracellular distribution of the antigen recognized by this antibody is presented. The monoclonal antibody recognizes a cell-surface and a cytoplasmic determinant. The density of the cell-surface determinant is heterogeneous ...

UNLABELLED INTRODUCTION Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expr...

Recent studies have implicated the complement system in pathogenesis of antineutrophil cytoplasmic antibody-associated vasculitis (AAV), prompting development novel therapeutic agents to target accordingly. The pivotal role component C5a, particular, has been subject a number phase II and III clinical trials. Indeed, US Food Drug Administration already approved avacopan, an oral C5a receptor in...

Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome are small- to medium-vessel vasculitides linked by overlapping pathology and the presence of antineutrophil cytoplasmic antibodies (ANCA). Commonly referred to as the ANCA-associated vasculitides, these diseases are challenging to diagnose and to treat. Distinguishing the ANCA-associated vasculitides from other forms...

Teaching NeuroImages: Myeloperoxidase–anti-neutrophil cytoplasmic antibody–positive hypertrophic pachymeningitis A woman in her 40s presents with painless monocular vision loss and is found to have optic perineuritis and dural thickening. Comprehensive laboratory testing,MRI of the brain, and dural biopsy reveal a diagnosis of myeloperoxidase–antineutrophil cytoplasmic antibody–positive hypertr...

BACKGROUND Breast carcinoma in situ (CIS) is classified into ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). DCIS is treated with surgical excision while LCIS can be clinically followed with or without hormonal treatment. Thus, it is critical to distinguish DCIS from LCIS. Immunohistochemical (IHC) staining for E-cadherin is routinely used to differentiate DCIS from LCIS i...

Anti neutrophil cytoplasmic antibody (ANCA) is strongly associated with some vasculitic disorders. Behçet's disease (BD) is a systemic vasculitis of unknown etiology. In this study, ANCA was found to be positive in 8 out of 66 patients (10.2%) with BD by combination testing consisting of immunofluorescence and ELISA [one patient showed an atypical pattern by indirect immunofloresence techique, ...

PURPOSE OF REVIEW The primary idiopathic small-vessel vasculitis syndromes include granulomatosis with polyangiitis, Churg-Strauss syndrome, and microscopic polyangiitis. These disorders are commonly referred to as antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides and prominently affect the pulmonary vasculature. Although significant progress has been made in the management of ...
