Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is usually a multisystem disorder, and pulmonary renal syndrome is a common presentation. Patients with AAV are less likely to experience relapse when they progress to end-stage renal disease (ESRD). We report a rare case of diffuse alveolar hemorrhage (DAH) in relapsing AAV after eight years of haemodialysis. A 58-year-old woman was admitted to our hospital with the chief complaints of dyspnea and hemoptysis accompanied by anemia, fever, fatigue, and weight loss...

ANCA-associated vasculitis (AAV) is characterized by inflammation and destruction of small and medium-sized vessels. Current management strategies for AAV have been validated in large groups of patients. However, recent insights indicate that distinct patient subsets may actually exist within AAV, thereby justifying the development of more personalized treatment strategies. In this review, we discuss current evidence for a better classification of AAV based on ANCA type. We describe how thus defined categories of AAV patients may differ in genetic background, clinical presentation, immune pathology, response to treatment and disease outcome...

PURPOSE: We report the case of a 59-year-old man with chronic hepatitis B and C infection presenting with acute kidney injury and enterococcus faecalis-infective endocarditis (IE). An elevated proteinase-3 (PR3)-ANCA and pauci-immune glomerulonephritis (GN) on renal biopsy were discovered, corresponding to ANCA-mediated GN. We conducted a literature review to assess the role of ANCA in IE and treatment implications. METHODS: On systematic review of the literature, we found five previous cases whereby IE caused by streptococcus and bartonella species were related to ANCA vasculitis-associated GN...

AIM: To determinate the prognostic significance of low serum C3 at the time of diagnosis of ANCA-associated vasculitis (AAV). METHODS: Our cohort included 75 consecutive patients with AAV diagnosed from January 2005 to December 2015. C3 levels were measured at the time of diagnosis. Patients were divided into two groups, those with low serum C3 levels (< 0.9 g/l) and those with normal serum C3 levels (0.9-1.8 g/l). We analysed association between serum C3 levels and both combined and singularly patient and renal survival (ESRD)...

A previously healthy 77-year-old Japanese man presented with a 2-week history of daily fevers peaking at 38°C, chills, hearing loss, and almost 10 kg of unintentional weight loss over 2 months. Pure tone audiometry showed mixed conductive-sensorineural hearing loss: right, 63.6 dB, left, 80.0 dB. Blood tests after admission showed a high myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) level (>300 U/mL), so we suspected ANCA-related vasculitis. The Japanese Otorhinolaryngology Society has recently been advocating the concept of otitis media with ANCA-associated vasculitis (OMAAV)...

OBJECTIVES: The treatment of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is based on remission-induction and remission-maintenance. Methotrexate is a widely used immunosuppressant but only a few studies explored its role for maintenance in AAV. This trial investigated the efficacy and safety of methotrexate as maintenance therapy for AAV. METHODS: In this single-centre, open-label, randomised trial we compared methotrexate and cyclophosphamide for maintenance in AAV...

This article presents the case of a patient with dyspnea, a history of poorly controlled asthma, sinonasal polyposis, blood eosinophilia and transient pulmonary infiltrates. The autoantibodies antinuclear antibodies, cytoplasmic anti-neutrophil cytoplasmic antibodies (c-ANCA) and perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) were negative. These symptoms are typical for eosinophilic granulomatosis with polyangiitis (EGPA, alternatively known as Churg-Strauss syndrome). The delay between onset and diagnosis in this case was several years...

The primary systemic vasculitides are heterogeneous, multisystem disorders characterized by inflammation and necrosis of small and medium blood vessels. Patients with antineutrophil cytoplasmic autoantibodies associated vasculitis have increased mortality rate as a consequence of cardiovascular disease. Measures to reduce the risk of cardiovascular disease should be integral to the management of systemic vasculitis. The preventive therapy for accelerated atherosclerosis in systemic vasculitis should be based on aggressive approach against inflammation and against risk factors of premature atherosclerosis such as hypertension, smoking, inactivity, obesity and unhealthy diet...

BACKGROUND: Targeted proteomics, which involves quantitative analysis of targeted proteins using selected reaction monitoring (SRM) mass spectrometry, has emerged as a new methodology for discovery of clinical biomarkers. In this study, we used targeted serum proteomics to identify circulating biomarkers for prediction of disease activity and organ involvement in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: A large-scale SRM assay targeting 135 biomarker candidates was established using a triple-quadrupole mass spectrometer coupled with nanoflow liquid chromatography...

PURPOSE OF REVIEW: Patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) have an increased malignancy risk compared with the general population. This review aims to evaluate recent evidence for changes in the incidence of malignancy in patients with AAV and to examine explanations for the association between AAV and malignancy. RECENT FINDINGS: The overall malignancy risk in patients with AAV has decreased, most likely as a result of recent changes in therapeutic regimen, that is, a decrease in the exposure to cyclophosphamide...

The European League Against Rheumatism recommendations for the management of antineutrophil cytoplasmic antibody-associated vasculitis have been recently published. Unique to recommendation development, they were also voted on by members of a learned society. This paper explores the wider validity of the recommendations among people who self-identify as clinicians caring for patients with vasculitis. In addition to the task force, a learned society (European Vasculitis Society-EUVAS) was invited, through online survey, to rate independently the strength of evidence of each recommendation to obtain an indication of the agreement among the final target audience and ultimate end-users of the recommendations...

Myeloperoxidase (MPO) anti-neutrophil cytoplasmic Ab (ANCA)-associated vasculitis results from autoimmunity to MPO. IL-17A plays a critical role in generating this form of autoimmune injury but its cell of origin is uncertain. We addressed the hypothesis that IL-17A-producing γδ T cells are a nonredundant requisite in the development of MPO autoimmunity and glomerulonephritis (GN). We studied MPO-ANCA GN in wild type, αβ, or γδ T cell-deficient (C57BL/6, βTCR(-/-) , and δTCR(-/-) respectively) mice...
