A 70-year-old man presented with proteinuria, microscopic hematuria, and an increased level of serum creatinine. systemic workup revealed that the patient had bronchogenic carcinoma anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis concurrently. Despite increase in cumulative number publications on paraneoplastic glomerulopathies, awareness link between cancer ANCA-assoc...

Antibodies to neutrophil cytoplasmic antigens (ANCA) are good serological markers for patients with mainly vasculitic conditions. Two main types of ANCAs have been detected, the first termed cytoplasmic antineutrophil cytoplasmic antibody (cANCA) are mainly associated with patients with Wegener's granulomatosis, the other termed perinuclear antineutrophil cytoplasmic antibody (pANCA) are mainly...

Neutrophils are pivotal to host defence during infectious diseases. However, activated neutrophils may also cause undesired tissue damage. Ample examples include small-vessel inflammatory diseases (vasculitis) that are associated with anti-neutrophil cytoplasmic autoantibodies (ANCA) residing in the patients' plasma. In addition to being an important diagnostic tool, convincing evidence shows t...

The objective was to evaluate the frequency of cytoplasmic and peripheral antineutrophil cytoplasmic antibodies (ANCA) in patients with leprosy, and to correlate the presence of ANCA with type and disease activity. Consecutive patients with leprosy were assessed clinically, and IgG ANCA were measured by indirect immunofluorescence. The presence of three of the following was used to assess disea...

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, ...

The anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides are a group of uncommon diseases characterised by inflammatory cell infiltration and necrosis of blood vessel walls. ANCA there has been considerable progress towards understanding their pathogenesis. This results in endothelial activation with increased transmigration and adherence of neutrophils to vessel walls. Specific ...
