Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides are a heterogeneous group of diseases corresponding to necrotising inflammation of small vessels with a wide range of clinical presentations. At least two of the diseases are believed to exhibit a common ground of pathophysiological mechanisms. These are granulomatosis with polyangiitis (GPA, formerly known as Wegeners granulomatosis) and microscopic polyangiitis (MPA). ANCA directed against proteinase 3 (PR3) are preferentially associated with GPA, and anti-myeloperoxidase (MPO) ANCA are associated mainly with MPA and eosinophilic GPA (formerly known as Churg-Strauss syndrome). Anti-MPO and anti-PR3 antibodies can activate neutrophils in vitro. In vivo data are available for humans and mice on the pathogenicity of anti-MPO but it is more controversial for PR3-ANCA. A recent genome-wide association study of patients with ANCA-associated vasculitides confirmed the genetic contribution to the pathogenesis of these conditions, with ...

Objective. Treatment resistance and relapse in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are major challenges for physicians. The aim of this study was to assess the risk factors for treatment resistance and relapse in a single-center cohort of Chinese patients with AAV.. Methods. Four hundred thirty-nine consecutive patients with AAV were recruited for inclusion in this study. The value of various clinical and pathologic parameters for the prediction of treatment resistance and relapse was analyzed.. Results. Treatment resistance occurred in 47 (10.7%) of 439 patients and was independently associated with a higher serum creatinine level (odds ratio [OR] 1.087, 95% confidence interval [95% CI] 1.001-1.180, P = 0.047), a higher erythrocyte sedimentation rate (OR 1.009, 95% CI 1.001-1.018, P = 0.025), therapy with corticosteroids plus cyclophosphamide (OR 0.115, 95% CI 0.051-0.256, P = 0.000), and the presence of muscle pain (OR 0.249, 95% CI 0.083-0.747, P = 0.013). ...

Objectives: Glucocorticoids (GCs) are a mainstay of treatment for patients with ANCA-associated vasculitis (AAV) but are associated with significant adverse effects. Effective remission induction in severe AAV using extremely limited GC exposure has not been attempted. We tested an early rapid GC withdrawal induction regimen for patients with severe AAV. Methods: Patients with active MPO- or PR3-ANCA vasculitis or ANCA-negative pauci-immune glomerulonephritis were included. Induction treatment consisted of two doses of rituximab, 3 months of low-dose CYC and a short course of oral GC (for between 1 and 2 weeks). Clinical, biochemical and immunological outcomes as well as adverse events were recorded. Results: A total of 49 patients were included, with at least 12 months of follow-up in 46. All patients achieved remission, with decreases observed in creatinine, proteinuria, CRP, ANCA level and BVAS. Three patients requiring dialysis at presentation became dialysis independent. Two patients ...

Introduction: Evidence from a number of open-label, uncontrolled studies has suggested that rituximab may benefit patients with autoimmune diseases who are refractory to standard-of-care. The objective of this study was to evaluate the safety and clinical outcomes of rituximab in several standard-of-care-refractory autoimmune diseases (within rheumatology, nephrology, dermatology and neurology) other than rheumatoid arthritis or non-Hodgkins lymphoma in a real-life clinical setting. Methods: Patients who received rituximab having shown an inadequate response to standard-of-care had their safety and clinical outcomes data retrospectively analysed as part of the German Registry of Autoimmune Diseases. The main outcome measures were safety and clinical response, as judged at the discretion of the investigators. Results: A total of 370 patients (299 patient-years) with various autoimmune diseases (23.0% with systemic lupus erythematosus, 15.7% antineutrophil cytoplasmic antibody-associated ...

Purpose: Combined use of cyclophosphamide (CYC) and glucocorticoids (GCS) has been the standard of care for remission induction for ANCA-associated vasculitis (AAV) for decades. Uncontrolled studies suggest rituximab (RTX) may be effective for AAV, and its use may avoid some of the toxicities associated with CYC therapy. This trial compares the efficacy of RTX to that of CYC for AAV.. Method: A multicenter, randomized, double-blind, placebo-controlled trial was conducted to determine if treatment with RTX (375 mg/m2 i.v. weekly x 4) was not inferior to CYC (2 mg/kg/d p.o.) for inducing remission in severe AAV. Once remission was achieved, CYC was replaced by azathioprine between months 3-6. All patients received the same GCS treatment protocol: 1-3 g i.v. methylprednisolone followed by prednisone 1 mg/kg/d p.o. reduced to 40 mg/d by month 1, and then tapered and discontinued completely by month 6. The primary endpoint was disease remission in the absence of prednisone therapy at month 6. ...

Background Secondary pulmonary hemorrhage increases the risk of mortality in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV); plasma exchange therapy may improve outcomes in these patients. We conducted a retrospective cohort study to investigate the effect of plasma exchange therapy on short-term prognoses in patients with pulmonary hemorrhage secondary to AAV. Methods This study utilized the Diagnosis Procedure Combination database, which is a nationwide inpatient database in Japan. We checked the abstract data and medical actions and identified the patients with pulmonary hemorrhage secondary to AAV who required proactive treatment between 2009 and 2014. To compare the in-hospital mortality, we performed propensity score matching between the plasma exchange and non-plasma exchange groups at a ratio of 1:1. Results Of the 52,932 patients with AAV, 940 developed pulmonary hemorrhage as a complication. A total of 249 patients from 194 hospitals were eligible for the

Antineutrophil cytoplasmic antibodies (ANCA) and Anti-glomerular basement membrane (GBM) antibodies often induce rapidly progressive glomerulonephritis (RPGN). Some reports have demonstrated RPGN with the sequential appearance of ANCA then anti-GBM antibodies, suggesting that ANCA may induce the development of anti-GBM antibodies. Whereas, many reports have shown that the development of ANCA is associated with various infectious diseases, such as non-tuberculous mycobacterial infection. A 65-year-old woman with pulmonary non-tuberculous mycobacterial (NTM) infection was monitored without treatment. One year later, serum myeloperoxidase (MPO)- ANCA were elevated (14.1 U/mL (normal value | 3.0 U/ml)). A high fever and RPGN appeared 1 year later, and serum MPO-ANCAs were 94.1 U/mL. Anti-GBM antibodies were also detected. A renal biopsy revealed crescentic glomerulonephritis with linear deposits of IgG and C3c along the GBM and interstitial inflammation with endarteritis of arterioles. The diagnosis was

The etiology of anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitides (AAV) is unknown, but the association between infections and autoimmunity has been studied extensively. In 2004, a novel theory was proposed that could link infection and autoimmunity. This theory of autoantigen complementarity was based on the serendipitous finding of antibodies against complementary-PR3 (cPR3) in patients with PR3-ANCA-associated vasculitis. cPR3 demonstrated homology to several bacterial proteins, and it was hypothesized that PR3-ANCA develop in response to anti-cPR3 antibodies, as a consequence of the anti-idiotypic network. These data have not been confirmed in other patient cohorts. We investigated the presence of anti-cPR3 antibodies in a Dutch cohort of PR3-ANCA-associated vasculitis patients. Anti-cPR3 reactivity was determined in serum using ELISA. Two separate batches of cPR3 were used to determine reactivity in two separate cohorts of PR3-ANCA-associated vasculitis patients. We ...

In this study, we investigated the mechanism of platelet activation in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), as well as the activation of the alternative complement pathway by platelets in AAV. CD62P and platelet-leukocyte aggregates in AAV patients were tested by flow cytometry. Platelets were stimulated by plasma from active AAV patients. The effect of the thrombin-protease-activated receptors (PARs) pathway was evaluated by blocking thrombin or PAR1 antagonists. After platelets were activated by plasma from AAV patients, Ca/Mg-Tyrodes buffer and Mg-EGTA buffer were used to measure complement activation in liquid phase and on the surface of platelets. The levels of CD62P-expressing platelets and platelet-leukocyte aggregates were significantly higher in active AAV patients than those in remission and normal controls. Platelets were activated by plasma from active AAV patients (percentage of CD62P-expressing platelets, 97.7 ± 3% vs. 1 ± 0.2%, p | 0

Most patients with ANCA-associated vasculitis will not present with visual or other overt signs of renal involvement: macroscopic haematuria is usually absent as one of the presenting symptoms and proteinuria is frequently mild, not leading to the clinical signs of nephrotic syndrome. This is also nicely illustrated by the paper by Houben as only 21 of the patients from their cohort were diagnosed by the renal department. This means that patients present with combinations of other signs and symptoms and are referred to other disciplines. Renal involvement, therefore, has to be actively investigated once the diagnosis of ANCA-associated vasculitis is suspected. This means that in every patient in whom the diagnosis of ANCA-associated vasculitis is seriously considered, assessment of renal function (serum creatinine, estimated glomerular filtration rate (eGFR), 24-hour urine creatinine clearance) and urinalysis (erythrocyturia and if present urinary microscopy for glomerular erythrocyturia and/or ...

Objectives: There are few data on clinical profiles of ANCA-associated vasculitis (AAV) in different ethnic populations. The aim of this study was to examine the differences in the ANCA type and clinical features of AAV between populations using the Diagnostic and Classification Criteria in Vasculitis Study (DCVAS) dataset. Methods: The DCVAS is an international, multicentre, observational study recruiting in 133 sites. Eight ethnic categories were analysed: Northern European, Caucasian American, Southern European, Middle Eastern/Turkish, Chinese, Japanese, Indian subcontinent and other. ANCA type was categorized as myeloperoxidase (MPO), PR3 and ANCA negative. Organ system involvement was recorded using a standard dataset. Differences were analysed by chi-squared tests using a Bonferroni correction and logistic regression (adjusting for age and sex). Northern European was the reference population. Results: Data from 1217 patients with AAV were available and the 967 (79.5%) patients recruited by

The main result of our analysis is that in AAV patients with predominant renal and pulmonary involvement, comorbidity score independently predicted short term survival. It also proved to be a predictor of infectious mortality. On protocolized immunosuppressive therapy, patients, who had high BVAS at baseline, had significantly poorer short term survival and more frequent relapses than subjects with lower than median score. When analyzing early and late mortality separately, BVAS did not predict outcome in univariable analysis.. BVAS, originally designed to standardize disease assessment in AAV, shows good correlation with clinical activity of the disease [8]. Flossmann et al. documented, that BVAS was a significant predictor of mortality by analyzing the data of patients recruited for randomized controlled trials. Patients in that study were somewhat different from the ones enrolled in ours, since the median BVAS was lower, renal function was less severely compromised, and subjects with ...

The treatment strategy for MPA follows that of GPA, as most of the data regarding treatment comes from trials that have included patients with both diseases (under the term ANCA associated vasculitis). Treatment should be urgently instituted after confirming the diagnosis. In patients with severe organ-threatening or life-threatening manifestations, high dose glucocorticoids may be used even while diagnostic confirmation is in progress. Treatment of MPA involves two-stages: induction of remission and maintenance of remission. Induction therapy includes high dose glucocorticoids (typically prednisone 1 mg/kg/day with or without preceding intravenous methylprednisolone 1000 mg for 3 doses) along with methotrexate (MTX) or rituximab (RTX) for non-severe disease and cyclophosphamide (CYC) or RTX for severe disease should be used. Untreated severe MPA has high mortality. Glucocorticoids form the cornerstone of treatment. The choice of the second agent is determined by disease severity, which can be ...

A monoclonal antibody may pose less of a malignancy risk than cyclophosphamide in certain patients with vasculitis, researchers report.

Antibody-mediated and paraneoplastic autoimmune encephalitides (AE) present with a broad spectrum of clinical symptoms. They often lead to progressing inflammatory changes of the central nervous system with subacute onset and can cause persistent brain damage. Thus, to promptly start the appropriate and AE-specific therapy, recognition of symptoms, initiation of relevant antibody diagnostics and confirmation of the clinical diagnosis are crucial, in particular as the diseases are relatively rare. This standard operating procedure (SOP) should draw attention to the clinical presentation of AE, support the diagnostic approach to patients with suspected AE and guide through the necessary steps including therapeutic decisions, tumour screening and exclusion of differential diagnoses. Based on existing diagnostic algorithms, treatment recommendations and personal experiences, this SOP gives an overview of clinical presentation, diagnostic procedures and therapy in AE.

Extracellular adenosine, generated via the concerted action of CD39 and CD73, contributes to T-cell differentiation and function. Adenosine concentrations are furthermore influenced by adenosine deaminase binding protein CD26. Because aberrant T-cell phenotypes had been reported in anti-neutrophil cytoplasmic auto-antibody (ANCA)-associated vasculitis (AAV) patients, an impaired expression of these molecules on T-cells of AAV patients was hypothesized in the present study. While in AAV patients (n = 29) CD26 was increased on CD4+ lymphocytes, CD39 and CD73 were generally reduced on patients T-cells. In CD4+ cells significant differences in CD73 expression were confined to memory CD45RA- cells, while in CD4- lymphocytes differences were significant in both naïve CD45RA+ and memory CD45RA- cells. The percentage of CD4-CD73+ cells correlated with micro-RNA (miR)−31 expression, a putative regulator of factor inhibiting hypoxia-inducible factor 1 alpha (FIH-1), inversely with serum C-reactive protein

Anti-neutrophil cytoplasmic antibody (ANCA) - associated vasculitis (AAV) is a life-threatening autoimmune disease characterized by an antibody-mediated glomerulonephritis and necrotizing vasculitis. Apart from antibodies, T cells are also involved in disease pathogenesis. This review stresses the hallmarks of T cell-mediated pathology in AAV and highlights the characteristics of lesional and circulating T cells in the immune response in AAV. Circulating effector T-cell populations are expanded and are in a persistent state of activation. Circulating regulatory T-cell subsets are less well characterized but seem to be impaired in function. Lesional effector T cells are present in granulomas, vasculitic lesions, and nephritis. Lesional T cells usually show pro-inflammatory properties and promote granuloma formation. Apart from T cells, dendritic cells are abundantly present at the sites of inflammation and locally orchestrate the immune response. Targeting the above-mentioned T cell-mediated disease

Avacopan is noninferior, but not superior, to prednisone with respect to remission at week 26 for patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis.

N2 - BACKGROUND: Renal vasculitis presents as rapidly progressive glomerulonephritis and comprises of a group of conditions characterised by acute kidney injury (AKI), haematuria and proteinuria. Treatment of these conditions involve the use of steroid and non-steroid agents in combination with plasma exchange. Although immunosuppression overall has been very successful in treatment of these conditions, many questions remain unanswered in terms of dose and duration of therapy, the use of plasma exchange and the role of new therapies. This 2019 publication is an update of a review first published in 2008 and updated in 2015. OBJECTIVES: To evaluate the benefits and harms of any intervention used for the treatment of renal vasculitis in adults. SEARCH METHODS: We searched the Cochrane Kidney and Transplant ...

Human Heat Shock Protein 60 (hHSP60) has been implicated in autoimmunity through molecular mimicry, based on the high degree of homology with HSP65 of micro-organisms leading to autoimmune recognition of the human protein. Additionally, sequence homology between hHSP60 and myeloperoxidase (MPO) has been described. MPO is a major autoantigen in vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA). We hypothesized that infections may trigger the ANCA response against MPO through hHSP60. In 86 consecutive patients with ANCA-associated vasculitis (AAV), anti-hHSP60 and anti-mycobacterial HSP65 were measured by ELISA. Patients were compared with 69 healthy controls (HC). Continuous data between groups were compared using Wilcoxon signed rank test and Kruskal-Wallis test with Dunns post-test when appropriate. Correlations between data were derived using Spearman correlation. Odds ratios and 95% confidence intervals were obtained using Fishers exact test. At diagnosis, median anti-mHSP65

Results We included 857 patients (77% women), age 18-85 years, disease duration 0-58 years. Persons with SLE were younger 47(34-57) than persons with SSc 60(52-69) p,0.001 and AAV 62(49-69) p,0.001, and they had longer disease duration 10 (2-20) than both the SSc 2 (0-8) p,0.001 and the AAV 3 (0-8) p,0.001 groups.. SLE patients reported a higher anxiety level and more impact of fatigue on all analysed subscales compared to the AAV patients, and all but impact on daily activities compared to SSc.
