“…Antibodies ag ainst cytoplasmic constituents of neutrophils (ANCAs) were initially described in patients with glomerulonephritis and systemic vasculitis [39,40] . In UC patients, antibodies against nuclear antigens were reported by Calabresi et al in 1961 [41] and Nielsen et al in 1983 (granulocyte specific-ANA) [42] .…”

The aetiology of primary sclerosing cholangitis (PSC) is not known and controversy exists as to whether PSC should be denominated an autoimmune disease. A large number of autoantibodies have been detected in PSC patients, but the specificity of these antibodies is generally low, and the frequencies vary largely between different studies. The presence of autoantibodies in PSC may be the result of a nonspecific dysregulation of the immune system, but the literature in PSC points to the possible presence of specific antibody targets in the biliary epithelium and in neutrophil granulocytes. The present review aims to give an overview of the studies of autoantibodies in PSC, with a particular emphasis on the prevalence, clinical relevance and possible pathogenetic importance of each individual marker.

“…The association between ANCA and vasculitis was first described in 1982, in a short report describing the clinical course of eight patients diagnosed with a segmental necrotising glomerulonephritis. 1 The discovery of perinuclear and cytoplasmic patterns on indirect immunofluorescence (P-ANCA and C-ANCA) and the main specificities myeloperoxidase and proteinase 3 (PR3) were recognised in the 1980s. The AAV comprise granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA, previously known as Churg-Strauss syndrome).…”

The vasculitides are a heterogeneous group of conditions typified by their ability to cause vessel inflammation with or without necrosis. They present with a wide variety of signs and symptoms and, if left untreated, carry a significant burden of mortality and morbidity. The ANCA-associated vasculitides (AAV) are three separate conditions - granulomatosis with polyangiitis (GPA - formerly known as Wegener’s granulomatosis); microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA - previously known as Churg-Strauss Syndrome). This review examines recent developments in the pathogenesis and treatment of AAV

Objective. Human neutrophil elastase (HNE) and proteinase 3 (PR3) are structurally and functionally related. PR3 is the prominent target antigen for antineutrophil cytoplasmic antibodies (ANCAs) in Wegener's granulomatosis (WG). Reported frequencies of HNE ANCAs in WG and other autoimmune diseases range from 0% to 20%. We previously detected HNE ANCAs in patients with cocaine-induced midline destructive lesions (CIMDL). We tested the hypothesis that discrepancies in the reported frequencies of HNE ANCAs in patients with vasculitis may be related to differences in detection methods, and that HNE ANCA may be a marker for CIMDL.Methods. HNE ANCA reactivity in 25 patients with CIMDL was characterized and compared with that in a control cohort of 604 consecutive patients (64 with WG, 14 with microscopic polyangiitis [MPA], and 526 others) and 45 healthy volunteers. HNE ANCAs were measured by indirect immunofluorescence using a previously undescribed expression system for recombinant HNE and by direct and capture enzyme-linked immunosorbent assays using purified native HNE as target antigen.Results. Among patients with CIMDL, HNE ANCAs were detectable by 1 assay in 84%, by 2 assays in 68%, and by all 3 assays in 36%. Fifty-seven percent of HNE ANCA-positive CIMDL sera were also PR3 ANCA-positive by at least 1 assay. In contrast, only 8 (1.3%) of 604 control sera reacted with HNE in at least 1 assay, 3 (0.5%) reacted in 2 assays, and only 1 serum sample (0.16%) reacted in all 3 assays. Sera obtained from patients with WG or MPA were universally HNE ANCA-negative, as were sera obtained from healthy controls.Conclusion. Optimal sensitivity for HNE ANCA requires multimodality testing. HNE ANCAs are frequent in CIMDL but not in other autoimmune diseases, including classic ANCA-associated vasculitis. HNE ANCAs may discriminate between CIMDL and WG, whereas a positive test result for PR3 ANCA may not.
