Identifying persistent or relapsing disease in anti-neutrophil cytoplasmic autoantibody- associated vasculitis (AAV) remains a clinical challenge with an unmet need for reliable biomarker of multisystem disease. In this study, we confirm the first time that Raman spectroscopy offers novel cost-effective candidate to discriminate active from remission AAV excellent accuracy. Spectrochemical inte...

Enormous progress has been made during the last 25 years in our understanding of the aetiopathogenesis of the anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitides (AAV). This has led to improvements in early diagnosis, treatment and secondary prevention of these diseases. Nevertheless, there are still unmet needs in the AAV. With respect to diagnosis and follow-up, sensitive ...

Organizing pneumonia (OP) is a clinicopathological entity that occurs idiopathically or in association with several conditions, but there are few reports about myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-associated OP. We describe a patient with OP whose clinical conditions improved spontaneously. Moreover, serum MPO-ANCA titers paralleled the clinical activity of the diseas...

AIMS To study ulcerative colitis associated neutrophil cytoplasmic antibodies (p-ANCA) in respect of class and subclass distribution, antigen specificity, and (sub)cellular localisation of the antigen(s) to which these antibodies are directed. METHODS p-ANCA positivity was determined using the standard indirect immunofluorescence test (IIFT). The immunoglobulin (Ig) subclass distribution of p...

Sir, Tubulointerstitial diseases including tubulointerstitial nephritis (TIN) have an impact on overall renal function and eventual prognosis of renal diseases [1]. However, the detailed pathogenesis of human TIN has not been fully studied. Renal involvement in anti-neutrophil cytoplasmic antibody (ANCA)-associated diseases shows mainly glomerular lesion, especially necrotizing crescentic glome...

The genetics of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a complex area of investigation because of the low frequency of AAVs, the rarity of familial cases and the complexity of disease phenotypes. However, recent studies have been able to gather significant numbers of patients, and multicentre collaborative efforts have allowed the performance of two genome-wi...

ANCA-associated vasculitides are a well-known clinico-pathological group of systemic diseases comprising microscopic poliangiitis, granulomatosis with poliangiitis and eosinophilic granulomatosis with poliangiitis. This article shows contemporary treatment of this diseases with extensive literature review. Stepwise treatment of ANCA-associated vasculitides is divided into induction therapy and ...

Our previous study demonstrated that plasma levels of complement factor H (FH) were inversely associated with the disease activity of patients with anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). In addition to serving as an inhibitor of the alternative complement pathway, there is increasing evidence demonstrating direct regulatory roles of FH on several cell types...

Renal involvement is a common and often severe complication of anti-neutrophil cytoplasmic autoantibody (ANCA) associated vasculitides (AAV). With the exception of Churg-Strauss syndrome (CSS), where kidney involvement is not a prominent feature, renal disease is present in about 70% of patients with Wegener's granulomatosis, now called granulomatosis with polyangiitis (GPA) and in almost 100% ...

Short-chain fatty acids, particularly succinic acid, are major metabolic by-products of Bacteroides species. To determine their role as potential virulence factors in infections containing Bacteroides species, short-chain fatty acids were examined for their effect on the neutrophil respiratory burst. Succinate (30 to 50 mM) irreversibly impaired superoxide and hydrogen peroxide production in re...
