Anti-neutrophil cytoplasmic autoantibodies (ANCA) targeting proteinase 3 (PR3) and myeloperoxidase expressed by innate immune cells (neutrophils and monocytes) are salient diagnostic and pathogenic features of small vessel vasculitis, comprising granulomatosis with polyangiitis (GPA), microscopic polyangiitis, and eosinophilic GPA. Genetic studies suggest that ANCA-associated vasculitides (AAV) constitute separate diseases, which share common immunological and pathological features, but are otherwise heterogeneous...

BACKGROUND/OBJECTIVE: Several studies have identified predictors of relapse in antineutrophil cytoplasmic antibody-associated small-vessel vasculitis. However, the role of smoking as a risk factor of relapse has not been elucidated. Therefore, this study aimed to evaluate whether a history of smoking is a dose-dependent independent risk factor for antineutrophil cytoplasmic antibody-associated small-vessel vasculitis relapse. METHODS: This multicenter retrospective cohort study included 122 patients with granulomatosis with polyangiitis and microscopic polyangiitis (MPA) from 9 nephrology centers in Japan...

Massive pulmonary haemorrhage is a life-threatening and difficult-to-manage condition. In certain circumstances, traditional approaches for haemoptysis may not be effective. Here, we report a 64-year-old man presenting with dyspnoea and leg oedema. He was diagnosed with microscopic polyangiitis due to positive perinuclear anti-neutrophil cytoplasmic antibody and other supportive evidence. His hospital course was complicated with massive pulmonary haemorrhage, which led to hypoxic respiratory failure, shock, and pulseless electrical activity...

Recent data suggest the existence of a complement alternative pathway activation in the pathogenesis of antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV), a condition that remains poorly understood. This study aims to assess the clinical characteristics and outcomes of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) patients with regard to their plasma complement levels at diagnosis. A retrospective monocentric study carried out at Caen University Hospital led to the identification of proteinase-3- or myeloperoxidase-ANCA-positive GPA and MPA patients from January 2000 to June 2016 and from September 2011 to June 2016, respectively...

PURPOSE: Delta neutrophil index (DNI) represents the immature granulocytes count associated with neutrophil-consumption. We investigated whether DNI might be associated with Birmingham vasculitis activity score (BVAS) at diagnosis and could predict relapse during the follow-up in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). MATERIALS AND METHODS: We reviewed the medical records of 97 patients having DNI results. Twenty patients had granulomatosis with polyangiitis (GPA), 58 had microscopic polyangiitis (MPA), and 19 had eosinophilic GPA (EGPA)...

Vasculitides with positivity of autoantibodies to neutrophil leukocytes cytoplasm (ANCA, AAV) belong to primary vasculitides involving small and less commonly medium size blood vessels. Three different clinical types of AAV can be distinguished: granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis. Since these autoantibodies seem to be weak activity biomarkers of AAV new molecules and factors start to come up, e.g. neutrophil extracellular traps NET, several T-lymphocyte subpopulations and different immunoglobulins classes of ANCA...

Mean platelet volume (MPV) was known to be associated with the inflammatory burdens in various diseases, but not microscopic polyangiitis (MPA) yet. In this study, we investigated the association between MPV and Birmingham vasculitis activity score (BVAS) in 88 patients with MPA. We retrospectively reviewed the medical records of 88 patients with MPA. Clinical and laboratory data at diagnosis and partially at follow-up were collected. Linear regression analyses were used to clarify the association between MPV and BVAS...

Anti-neutrophil cytoplasmic antibodies (ANCA) are a group of autoantibodies that cause systemic vascular inflammation by binding to target antigens of neutrophils. These autoantibodies can be found in serum from patients with systemic small-vessel vasculitis and they are considered as a biomarker for ANCA-associated vasculitis (AAV). A conventional screening test to detect ANCA in the serum is indirect immunofluorescence study, and subsequently confirmed by enzyme-linked immunosorbent assay. A positive staining of ANCA can be classified into three main categories based on the staining patterns: cytoplasmic, perinuclear, and atypical...

The classification of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) remains controversial. The main objective of this study was to define the respective values of ANCA serotype-based classification, clinicopathological classification, and histopathological classification in predicting patient and renal outcomes in a Spanish cohort of patients with ANCA with specificity for myeloperoxidase, MPO-ANCA, versus ANCA with specificity for proteinase 3, PR3-ANCA. Two hundred and forty-five patients with ANCA-AAV and biopsy-proven renal involvement diagnosed between 2000 and 2104 were recruited in 12 nephrology services...

INTRODUCTION: Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are two related forms of systemic vasculitis. Patients with these conditions often experience relapses affecting various body systems. Here we describe rates of relapse and review healthcare costs resulting from relapse among patients with GPA/MPA. METHODS: Two groups of patients with GPA and MPA were selected from the MarketScan claims databases between 2011 and 2013 based on diagnosis codes...

Cutaneous leukocytoclastic vasculitis (LCV) can occur as skin-limited disease or as part a systemic vasculitis. Appropriate workup includes the evaluation of antineutrophil cytoplasmic antibodies (ANCAs), with a positive titer raising concern for the associated primary vasculitides including microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), or eosinophilic granulomatosis with polyangiitis (EGPA). In the absence of systemic findings, however, a drug etiology must also be considered. Tumor necrosis factor (TNF) inhibitors, propylthiouracil, levamisole-adulterated cocaine, hydralazine, and minocycline have been previously documented to induce ANCA-positive vasculitis (APV), which may present with conspicuously high ANCA titers...

Polyarteritis nodosa (PAN) is a rare form of primary systemic vasculitis with heterogeneous presentations, treatments and disease course. Historical approaches to classification and diagnostic terminology are reviewed. Since differentiation of PAN from microscopic polyangiitis (MPA) and other ANCA vasculitides by the Chapel Hill conference statements, and with hepatitis associated PAN defined as a secondary vasculitis, the phenotyping and subclassification of PAN has received little attention. Monogenic disorders similar to PAN have been described (familial Mediterranean fever, Adenosine Deaminase-2 deficiency), and cutaneous PAN and single organ vasculitis, discussed...

This study investigated the risk factors of peritonitis during early peritoneal dialysis for renal failure in patients with antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (AASV). This study enrolled hospitalized AASV patients with renal failure who underwent peritoneal dialysis at the Department of Nephrology of our hospital between 2008 and 2015. The primary aim of this study was to perform a retrospective analysis to characterize peritonitis during the early period (≤ 8 weeks) of dialysis, and to compare the differences in initial clinical manifestations, vasculitis activity, immunosuppressive therapies prior to the renal replacement therapy, and prognosis between patients with or without peritonitis...

The small vessel vasculitides granulomatosis with polyangiitis (GPA) and microscopic polyangiitis are associated with autoantibodies to neutrophil cytoplasm antigens (ANCA), principally proteinase-3 (PR3) and myeloperoxidase (MPO). There is an association between GPA and nasal carriage of Staphylococcus aureus. The recent finding that S. aureus produces proteins that bind tightly to and block the function of both PR3 and MPO suggests a mechanism for ANCA formation. The bacterial protein-autoantigen conjugate is recognised by B cells with ANCA specificity, internalised, and the bacterial protein processed and presented to T cells with specificity for bacterial peptides...
