Abstract
The KDIGO 2021 Clinical Practice Guideline for the Management of Glomerular Diseases represents the first update to this set of recommendations since the initial set of KDIGO guideline recommendations was published in 2012. The pace of growth in our molecular understanding of glomerular disease has quickened and a number of newer immunosuppressive and targeted therapies have been introduced since the original set of guideline recommendations, making such an update necessary. Despite these updates, many areas of controversy remain. In addition, further updates since the publication of KDIGO 2021 have occurred which this guideline does not encompass. With this commentary, the KDOQI work group has generated a chapter-by-chapter companion opinion article that provides commentary specific to the implementation of the KDIGO 2021 guideline in the United States.

Habibi MA, Alesaeidi S, Zahedi M, Hakimi Rahmani S, Piri SM, Tavakolpour S. The Efficacy and Safety of Rituximab in ANCA-Associated Vasculitis: A Systematic Review. BIOLOGY 2022; 11:biology11121767. [PMID: 36552276 PMCID: PMC9774915 DOI: 10.3390/biology11121767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/25/2022] [Accepted: 11/30/2022] [Indexed: 12/12/2022]
Abstract
Background and aim: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a rare multisystem autoimmune disease developed by autoantibody production against human neutrophilic granulocytes, including proteinase-3 (PR3) and myeloperoxidase (MPO). The management of AAV patients is difficult due to the multiorgan involvement, high rate of relapse, and complications of immunosuppressive agents that make it challenging. This study aims to investigate the efficacy and safety of rituximab (RTX) therapy in patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) subtypes. Method: The PubMed/Medline database was searched for any studies related to RTX therapy in ANCA-associated vasculitis (GPA and MPA subtypes), from inception to 1 August 2022, and proceeded in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: Our search resulted in 1082 initial records. After the elimination of review papers, irrelevant studies, and non-English records, 223 articles were included, and the data related to the efficacy and safety of RTX therapy were extracted. Several randomized and non-randomized studies showed that RTX is an effective treatment option for patients with AAV. Most of the studies showed the very effective effect of RTX in controlling disease in AAV patients, including pediatrics, adults, and elderlies, although RTX cannot completely prevent relapse. However, maintenance therapy helps delay the disease's relapse and causes sustained remission. Not only the licensed dose (375 mg/m2 intravenous per week for 4 weeks) could induce disease remission, but studies also showed that a single infusion of RTX could be effective. Although RTX could resolve many rare manifestations in AAV patients, there are few reports showing treatment failure. Additionally, few sudies have reported the unexpeted worsening of the disease after RTX administration. Generally, RTX is relatively safe compared to conventional therapies, but some serious adverse effects, mainly infections, cytopenia, hypogammaglobinemia, malignancy, and hypersensitivity have been reported. Conclusions: RTX is an effective and relatively safe therapeutic option for AAV. Studies on the evaluation of the safety profiles of RTX and the prevention of severe RTX-related side effects in AAV patients are required.

Front Immunol 2022; 12:803175. [PMID: 35095887 PMCID: PMC8789753 DOI: 10.3389/fimmu.2021.803175] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 12/15/2021] [Indexed: 12/12/2022] Open
Abstract
Background Time to relapse after rituximab for the treatment of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is variable, and optimal retreatment strategy has remained unclear. In AAV following rituximab induction, the study objective was to evaluate clinical and B-cell predictors of relapse in order to develop a retreatment algorithm. Methods A retrospective observational study was conducted in 70 rituximab-treated ANCA-associated vasculitis patients followed up for over 10 years. Complete response (CR) was defined as Birmingham Vasculitis Activity Score v3.0 = 0. Retreatment was given on clinical relapse, defined as new features or worsening of persistent disease (not by biomarker status). Peripheral B-cell subsets were measured using highly sensitive flow cytometry. Predictors were tested using multivariable Cox regression. Results Median time to retreatment for cycles 1–5 were 84, 73, 67, 60, and 73 weeks. Over 467 patient-years follow-up, 158 relapses occurred in 60 patients; 16 (in 15 patients) were major (renal = 7, neurological = 4, ENT = 3, and respiratory = 2). The major-relapse rate was 3.4/100 patient-years. In multivariable analysis, concomitant immunosuppressant [HR, 0.48 (95% CI, 0.24–0.94)], achieving CR [0.24 (0.12–0.50)], and naïve B-cell repopulation at 6 months [0.43 (0.22–0.84)] were associated with longer time to relapse. Personalized retreatment using these three predictors in this cohort would have avoided an unnecessary fixed retreatment in 24% of patients. Area under the receiver operating characteristic for prediction of time to relapse was greater if guided by naïve B-cell repopulation than if previously evaluated ANCA and/or CD19+ cells return at 6 months had been used, 0.82 and 0.53, respectively. Conclusion Our findings suggest that all patients should be coprescribed oral immunosuppressant. Those with incomplete response or with absent naïve B cells should be retreated at 6 months. Patients with complete response and naïve repopulation should not receive fixed retreatment. This algorithm could reduce unnecessary retreatment and warrant investigation in clinical trials.

Abstract
Objective The objective of this study was to compare the efficacy and safety of two rituximab (RTX) regimens for the induction of remission in severe antineutrophil cytoplasm antibody–associated vasculitis (AAV): the four‐dose (375 mg/m2 intravenously weekly) versus the two‐dose (1000 mg intravenously biweekly) regimen. Methods A systematic review was performed to identify studies using the four‐ and/or two‐dose RTX regimens for induction of remission in severe AAV. Disease status 6 months after RTX infusion was required for inclusion. Patients were excluded if they received concomitant cyclophosphamide or plasma exchange. The primary end point was the proportion of patients in complete remission at 6 months. The pooled estimate was obtained by using meta‐analysis methods for proportions with random effects. Secondary end points included antineutrophil cytoplasm antibody status, number of patients with B‐cell depletion, mean prednisone dose, infections, and death. Results A total of 27 studies and 506 patients were included for analysis: 361 patients received the four‐dose regimen, and 145 patients received the two‐dose regimen. Most patients had relapsing disease at inclusion (83% and 92% of patients, respectively). There was no significant difference between the four‐ and two‐dose regimens, with a complete remission achieved in 85% (95% confidence interval [CI]: 70‐96) and 91% (95% CI: 79‐99) of patients, respectively. At 6 months, both regimens were associated with a similar mean daily prednisone dose (8.1 mg), infections (12% in both), and death (1% vs 0%, respectively). Conclusion No difference was found in terms of efficacy or safety between the four‐ and two‐dose RTX regimens for induction of remission in severe AAV.

Abstract
Introduction: Anti-neutrophil cytoplasm autoantibodies (ANCA)-associated vasculitides (AAVs) are a group of rare heterogeneous diseases characterized by blood vessel inflammation resulting in organ destruction and death. Although various treatment strategies have resulted in marked improvement in vasculitis-specific outcomes, many patients with AAV continue to suffer from complications related to the prolonged use of glucocorticoids (GC) such as infections, metabolic abnormalities, and increased cardiovascular morbidity. Recently, activation of the alternative complement pathway has been implicated in the augmentation of the damage caused by AAV via the complement C5a receptor (C5aR1, CD88). Specifically targeting this pathway may lead to improved outcomes in patients with AAV.Areas covered: In this article, we have summarized the rationale for targeting the complement pathway in AAV. The relevant pre-clinical, phase I, II and III findings with emphasis on the efficacy, and safety of avacopan, a new oral competitive inhibitor that interferes with the binding of C5a to C5aR1 (CD88), are reviewed.Expert opinion: These results are encouraging, may led to major changes in the treatment approach for AAV, and give rise to future studies utilizing complement inhibitors in AAV patients, and potentially in other immune mediated diseases.

Abstract
The analysis of the mechanisms of the formation of a rare clinical combination of pulmonary embolism (PE) and diffuse alveolar hemorrhage (DAH), which are complications of systemic vasculitis associated with antibodies to the cytoplasm of neutrophils (primarily granulomatosis with polyangiitis), systemic lupus erythematosus and secondary antiphlogistic syndrome primary antiphospholipid syndrome and Goodpastures syndrome. Taking into account the chronological sequence of the occurrence of PE and DAH, 3 variants of the onset of these potentially fatal additions to the underlying disease were considered: the anticipatory DAH development of PE, delayed from DAH PE and joint (within 24 hours) formation of PE and DAH. A review of single descriptions of such a combination of complications of granulomatosis with polyangiitis is carried out, criteria are indicated, a working classification of severity is given and, taking this into account, a modern program of therapy for DAH as an independent event and in combination with PE.

Abstract
BACKGROUND The value of myeloperoxidase and proteinase 3 antibodies titers in the assessment of renal disease activity and flare prediction in patients with ANCA-associated-vasculitis (AAV) is not well-known. METHODS Retrospective study including 113 AVV patients with a renal biopsy-proven pauci-immune necrotizing glomerulonephritis from seven Spanish hospitals. The main inclusion criteria were assessment of MPO antibodies (MPOab) using multiplex flow immunoassay and PR3 antibodies (PR3ab) measurements using immunoassay chemiluminescence with an identical range of values for all participating centers. RESULTS Serum MPOab, 3 ± 1.2 months before relapse, was higher in patients who relapsed (19.2 ± 12.2 vs 3.2 ± 5.1 AI, p < 0.001). The discrimination value of MPOab 3 months before renal relapse had an AUC of 0.82 (95%CI 0.73-0.92; p < 0.001). ΔMPOab (change in antibodies titration 6 months before relapse) was higher in patients who relapsed [8.3 ± 12 vs 0.9 ± 3.1 AI, p = 0.001) (AI; antibody index unit). The discrimination value of ΔMPO had an AUC of 0.76 (95%CI 0.63-0.88; p < 0.001). The positive predictive value of renal relapse in PR3 patients is 100% and the negative predictive value of renal relapse in patients with PR3 positive titers is 57.1%. Serum PR3ab was higher in patients who relapsed 2.8 ± 1.4 months before relapse (58.6 ± 24.6 vs 2.0 ± 0.6 AI, p < 0.001). CONCLUSIONS MPO antibody level monitorization using multiplex flow immunoassay and PR3 measurements using immunoassay chemiluminescence are useful and sensitive tools for the prediction of renal relapse in the follow-up of AAV patients with renal disease, and relevant surrogate markers of renal disease activity.

Abstract
Treatment of vasculitides associated with anti-neutrophil cytoplasm antibodies (ANCA) (AAVs) has evolved dramatically in recent years, particularly since the demonstration of rituximab efficacy as remission induction and maintenance therapy for granulomatosis with polyangiitis and microscopic polyangiitis. In 2013, the French Vasculitis Study Group (FVSG) published recommendations for its use by clinicians. Since then, new data have made it possible to better specify and codify prescription of rituximab to treat AAVs. Herein, the FVSG Recommendations Committee, an expert panel comprised of physicians with extensive experience in the treatment and management of vasculitides, presents its consensus guidelines based on literature analysis, the results of prospective therapeutic trials and personal experience.

Abstract
Posterior scleritis is a rare sight-threatening condition that typically presents with an acutely painful eye, often with associated reduced visual acuity. Diagnosis can be challenging and requires specialist ophthalmological assessment. Consequences of delayed treatment include permanent loss of vision. We present a case of posterior scleritis initially managed as periorbital cellulitis. We highlight the importance of broad differential diagnoses when assessing painful periorbital swelling, and present a review of current management strategies for posterior scleritis.

Abstract
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 Register of Studies up to 21 November 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA Randomised controlled trials investigating any intervention for the treatment of renal vasculitis in adults. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Statistical analyses were performed using a random effects model and results expressed as risk ratio (RR) with 95% confidence intervals (CI) for dichotomous outcomes or mean difference (MD) for continuous outcomes. MAIN RESULTS Forty studies (3764 patients) were included. Studies conducted earlier tended to have a higher risk of bias due to poor (or poorly reported) study design, broad inclusion criteria, less well developed disease definitions and low patient numbers. Later studies tend to have improved in all areas of quality, aided by the development of large international study groups. Induction therapy: Plasma exchange as adjunctive therapy may reduce the need for dialysis at three (2 studies: RR 0.43, 95% CI 0.23 to 0.78; I2 = 0%) and 12 months (6 studies: RR 0.45, 95% CI 0.29 to 0.72; I2 = 0%) (low certainty evidence). Plasma exchange may make little or no difference to death, serum creatinine (SCr), sustained remission or to serious or the total number of adverse events. Plasma exchange may increase the number of serious infections (5 studies: RR 1.26, 95% CI 1.03 to 1.54; I2 = 0%; low certainty evidence). Remission rates for pulse versus continuous cyclophosphamide (CPA) were equivalent but pulse treatment may increase the risk of relapse (4 studies: RR 1.79, 95% CI 1.11 to 2.87; I2 = 0%) (low certainty evidence) compared with continuous cyclophosphamide. Pulse CPA may make little or no difference to death at final follow-up, or SCr at any time point. More patients required dialysis in the pulse CPA group. Leukopenia was less common with pulse treatment; however, nausea was more common. Rituximab compared to CPA probably makes little or no difference to death, remission, relapse, severe adverse events, serious infections, or severe adverse events. Kidney function and dialysis were not reported. A single study reported no difference in the number of deaths, need for dialysis, or adverse events between mycophenolate mofetil (MMF) and CPA. Remission was reported to improve with MMF however more patients relapsed. A lower dose of steroids was probably as effective as high dose and may be safer, causing fewer infections; kidney function and relapse were not reported. There was little of no difference in death or remission between six and 12 pulses of CPA. There is low certainty evidence that there were less relapses with 12 pulses (2 studies: RR 1.57, 95% CI 0.96 to 2.56; I2 = 0%), but more infections (2 studies: RR 0.79, 95% CI 0.36 to 1.72; I2 = 45%). One study reported severe adverse events were less in patients receiving six compared to 12 pulses of CPA. Kidney function and dialysis were not reported. There is limited evidence from single studies about the effectiveness of intravenous immunoglobulin, avacopan, methotrexate, immunoadsorption, lymphocytapheresis, or etanercept. Maintenance therapy: Azathioprine (AZA) has equivalent efficacy as a maintenance agent to CPA with fewer episodes of leucopenia. MMF resulted in a higher relapse rate when tested against azathioprine in remission maintenance. Rituximab is an effective remission induction and maintenance agent. Oral co-trimoxazole did not reduce relapses in granulomatosis with polyangiitis. There were fewer relapses but more serious adverse events with leflunomide compared to methotrexate. There is limited evidence from single studies about the effectiveness of methotrexate versus CPA or AZA, cyclosporin versus CPA, extended versus standard AZA, and belimumab. AUTHORS' CONCLUSIONS Plasma exchange was effective in patients with severe AKI secondary to vasculitis. Pulse cyclophosphamide may result in an increased risk of relapse when compared to continuous oral use but a reduced total dose. Whilst CPA is standard induction treatment, rituximab and MMF were also effective. AZA, methotrexate and leflunomide were effective as maintenance therapy. Further studies are required to more clearly delineate the appropriate place of newer agents within an evidence-based therapeutic strategy.

Abstract
In recent decades, antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis has transformed from an almost uniformly fatal disease to a treatable form of primary systemic vasculitis. Substantial disease heterogeneity exists within ANCA-associated vasculitis and the increasing understanding of this heterogeneity has implications for guiding treatment decisions. Approaches to induction and maintenance therapy vary depending on disease severity, clinical manifestations, and patient-specific factors. In this narrative Review, we examine how disease heterogeneity in ANCA-associated vasculitis, with respect to disease severity, clinical presentations, and ANCA specificity, influences therapeutic decision making. Many questions regarding therapeutic strategies in ANCA-associated vasculitis remain unanswered, and these should guide future research in this complex group of diseases.

Abstract
OBJECTIVE To evaluate the clinical efficacy and safety of off-label biological therapies in patients with ANCA-associated vasculitis (AAV) and non-ANCA-associated small-vessel vasculitis (nAAV) in clinical practice. METHODS The German Registry in Autoimmune Diseases 2 (GRAID2) is a national, retrospective, non-interventional, multicentre observational study (August 2006 until December 2013) on patients with autoimmune diseases refractory to standard immunosuppressive therapy treated with off-label biologicals. RESULTS Data from 64 patients (20.6% of all GRAID2 patients) were collected: 54 patients (84.4%) had ANCA-associated vasculitis (AAV) and 10 patients (15.6%) had non-ANCA-associated small-vessel vasculitis (nAAV). Of the AAV patients, 96.3% were treated off-label with rituximab (RTX) and 3.7% with tumor necrosis factor alpha (TNFα)-inhibitors. Of patients with nAAV, 30% were treated with RTX, 60% with TNFα-inhibitors, and 10% with tocilizumab. The main reasons for off-label biological treatment in AAV patients were pulmonary, renal, or ear, nose, and throat involvement. These manifestations clearly improved in most patients after off-label biological therapy was initiated. Daily glucocorticoid dosage could be reduced. The off-label biological therapy was generally well tolerated. In AAV patients, 4.18 severe infections per 100 patient years were observed. There was one death in the nAAV group caused by fungal infection and ileus. A correlation between this fatality and RTX treatment was regarded as possible. CONCLUSION Safety and efficacy of off-label RTX-treatment in AAV-patients could be assessed in the GRAID2 data. Results point to good efficacy and safety of RTX in this special patient cohort and support the approval of RTX for AAV induction therapy.

Abstract
Background: During the past years biologic agents (also termed biologicals or biologics) have become a crucial treatment option in immunological diseases. Numerous articles have been published on biologicals, which complicates the decision making process on the use of the most appropriate biologic for a given immune-mediated disease. This systematic review is the first of a series of articles assessing the safety and efficacy of B cell-targeting biologics for the treatment of immune-mediated diseases. Objective: To evaluate rituximab's safety and efficacy for the treatment of immune-mediated disorders compared to placebo, conventional treatment, or other biologics. Methods: The PRISMA checklist guided the reporting of the data. We searched the PubMed database between 4 October 2016 and 26 July 2018 concentrating on immune-mediated disorders. Results: The literature search identified 19,665 articles. After screening titles and abstracts against the inclusion and exclusion criteria and assessing full texts, 105 articles were finally included in a narrative synthesis. Conclusions: Rituximab is both safe and effective for the treatment of acquired angioedema with C1-inhibitor deficiency, ANCA-associated vasculitis, autoimmune hemolytic anemia, Behçet's disease, bullous pemphigoid, Castleman's disease, cryoglobulinemia, Goodpasture's disease, IgG4-related disease, immune thrombocytopenia, juvenile idiopathic arthritis, relapsing-remitting multiple sclerosis, myasthenia gravis, nephrotic syndrome, neuromyelitis optica, pemphigus, rheumatoid arthritis, spondyloarthropathy, and systemic sclerosis. Conversely, rituximab failed to show an effect for antiphospholipid syndrome, autoimmune hepatitis, IgA nephropathy, inflammatory myositis, primary-progressive multiple sclerosis, systemic lupus erythematosus, and ulcerative colitis. Finally, mixed results were reported for membranous nephropathy, primary Sjögren's syndrome and Graves' disease, therefore warranting better quality trials with larger patient numbers.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of systemic necrotizing vasculitides that includes granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis. Treatment of these conditions has improved during the past 2 decades with better understanding of these conditions and availability of newer agents. Cyclophosphamide (CYC) was the first drug demonstrated to afford successful treatment and improvement in AAV. With the emergence of newer agents with more favorable safety profiles, CYC is no longer the cornerstone of management of AAV. This article reviews existing data for treatment and the current role of CYC in the management of AAV.

Abstract
Granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis) and microscopic polyangiitis (MPA) are associated with the detection of antibodies against neutrophilic cytoplasmic antigens (ANCA) and are referred to as ANCA-associated vasculitides (AAV). In the event of the clinical suspicion of AAV the ANCA should first be determined by means of an antigen-specific immunoassay for proteinase 3‑ANCA and myeloperoxidase-ANCA, according to current consensus recommendations. The diagnosis of AAV should also be confirmed by biopsy if possible. The classification criteria for AAV are currently being revised. Diagnostic criteria do not exist. The standard induction therapy consists of rituximab or cyclophosphamide, each in combination with glucocorticoids (GC). In the absence of severe organ involvement, methotrexate can alternatively be used. Recent study data suggest that additive plasmapheresis does not improve the long-term outcome. After remission, remission-preserving treatment with azathioprine, methotrexate or rituximab should be given for at least 48 months. The risk of severe infections is markedly increased, especially during the remission induction phase but can also be reduced during treatment with rituximab by the prophylactic administration of trimethoprim-sulfamethoxazole. In view of the increased risk of infection, GC-reduced or GC-free treatment regimens are currently the focus of clinical development.

Abstract
Antineutrophil cytoplasmic antibodies (ANCAs) are autoantibodies specific for antigens located in the cytoplasmic granules of neutrophils and lysosomes of monocytes. ANCAs are associated with a spectrum of necrotizing vasculitis that includes granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis. Pulmonary vasculitis and related extravascular inflammation and fibrosis are frequent components of ANCA vasculitis. In this review, we detail the factors that have been associated with the origin of the ANCA autoimmune response and summarize the most relevant clinical observations, in vitro evidence, and animal studies strongly indicating the pathogenic potential of ANCA. In addition, we describe the putative sequence of pathogenic mechanisms driven by ANCA-induced activation of neutrophils that result in small vessel necrotizing vasculitis and extravascular granulomatous necrotizing inflammation.

Abstract
Targeted immunotherapy is substantially improving the management of ANCA-associated vasculitides (AAV), which include granulomatosis with polyangiitis (GPA, Wegener's granulomatosis), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome). This article reviews the current role for targeted immunotherapy in AAV, its validated indications, and avenues for further development. Rituximab is a validated induction treatment for GPA and severe MPA. Rituximab in these indications is not less effective than cyclophosphamide and is particularly useful in patients with refractory or relapsing disease, women of childbearing potential, and patients previously treated with cyclophosphamide. Rituximab is more effective than cyclophosphamide for treating relapses. For remission maintenance therapy, which is indispensable, rituximab has been proven superior over conventional immunosuppressive treatment. Rituximab is licensed in the USA and in Europe for the induction treatment of severe forms of GPA and MPA. An extension study for remission maintenance therapy is ongoing. In EGPA, although maintenance treatment with the interleukin-5 antagonist mepolizumab is effective in decreasing glucocorticoid requirements and in alleviating asthma and sinonasal symptoms, its efficacy on the vasculitis remains somewhat unclear. Mepolizumab is licensed for use in EGPA, and rituximab is also being evaluated as an induction and maintenance agent. Immunoglobulins can be helpful as an adjuvant treatment for active AAV with severe immunedepression, notably when infections occur. Plasma exchange is indicated in AAV with advanced renal dysfunction and, perhaps, in the event of alveolar hemorrhage, a possibility that will be assessed in 2018 in a large international study.

Abstract
PURPOSE OF REVIEW The purpose of this study is to describe the most relevant advances concerning lung involvement in the ANCA-associated vasculitides (excluding eosinophilic granulomatosis with polyangiitis which may have different disease mechanisms). Focus is on pathophysiology, recent important imagenological procedures, treatment, and outcome. RECENT FINDINGS Emerging information exists on potential newly investigated diagnostic procedures (v.g. transbronchial cryobiopsies), detailed tomographic abnormalities, the potential favorable role of rituximab and the still uncertain one of plasma exchange in the treatment, and the increasing description of interstitial lung disease. Survival is reduced in case of both, diffuse alveolar hemorrhage and diffuse parenchymal disease. There is the need to expand the knowledge concerning better long-term treatment options with specific regimes, and to incorporate other measures regarding integral treatment in patients afflicted with lung involvement these maladies, as the outcome seems adverse in this scenario.

Abstract
Renal involvement with rapidly progressive glomerulonephritis is a common manifestation of antineutrophil cytoplasmic antibody (ANCA) associated vasculitides, which is characterized by end-stage renal disease and high mortality rates in untreated and/or late referral patients. The long-term renal survival has improved dramatically since the addition of cyclophosphamide (CYC) and recently of rituximab (RTX) in association with corticosteroids in the remission induction therapeutic regimens. However, renal prognosis remains unfavorable for many patients and the mortality rate is still significantly high. In this review, we analyze the open challenges to be addressed to optimize the induction remission therapy, principally in patients with advanced kidney failure. This concern the first-line therapy (CYC or RTX) based on different parameters (estimated glomerular filtration rate at baseline, new or relapsed disease, ANCA specificity, tissue injury, safety), the role of plasma exchange and the role of new therapies. Indeed, we discuss future perspectives in induction remission therapy by reporting recent advances in new targeted therapies with particular reference to avacopan, an orally administered selective C5a receptor inhibitor.

Abstract
Objectives To study the determinants of the pharmacokinetics (PK) of rituximab (RTX) in patients with ANCA-associated vasculitis (AAV) and its association with clinical outcomes. Methods This study included data from 89 patients from the RTX in AAV trial who received the full dose of RTX (four weekly infusions of 375 mg/m2). RTX was quantified at weeks 2, 4, 8, 16 and 24, and summarized by computing the trapezoidal area under the curve. We explored potential determinants of the PK-RTX, and analysed its association with clinical outcomes: achievement of remission at 6 months, duration of B-cell depletion and time to relapse in patients who achieved complete remission. Results RTX serum levels were significantly lower in males and in newly diagnosed patients, and negatively correlated with body surface area, baseline B-cell count and degree of disease activity. In multivariate analyses, the main determinants of PK-RTX were sex and new diagnosis. Patients reaching complete remission at month 6 had similar RTX levels compared with patients who did not reach complete remission. Patients with higher RTX levels generally experienced longer B-cell depletion than patients with lower levels, but RTX levels at the different time points and area under the curve were not associated with time to relapse. Conclusion Despite the body-surface-area-based dosing protocol, PK-RTX is highly variable among patients with AAV, its main determinants being sex and newly diagnosed disease. We did not observe any relevant association between PK-RTX and clinical outcomes. The monitoring of serum RTX levels does not seem clinically useful in AAV.

Abstract
Hepatitis C Virus (HCV)-related Mixed Cryoglobulinemia (MC) is a unique condition with complex pathogenesis that involves HCV antigen-driven B-lymphocyte clonal proliferation and mutagenesis. Clinical spectrum of MC ranges from asymptomatic state to clinically-apparent vasculitis involving multiple organs. In the era of Direct-Acting Antiviral (DAA) therapy, patients with HCV-related MC achieve high rates of viral clearance that is commonly accompanied by an improvement in clinical symptoms as well as immunological profiles. Rituximab, either alone or in combination with DAA, has also been shown to be effective. Nevertheless, there have been limited and somewhat conflicting data, particularly over the long-term, regarding the rate and degree of clinical response of MC following DAA therapy. It appears that we have come quite a long way in the last decade with this condition. As with non-MC related HCV, undoubtedly long term outcome data will be forthcoming over the next few years. As we move forward successful therapy of HCV is not likely to be a challenge in contrast to access to therapy.

Abstract
Rituximab (RTX) is becoming a standard treatment for patients with anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) but heterogeneity exists regarding its use. We present our uncontrolled experience with RTX in patients with refractory AAV and also the results of a systematic review of non-randomized studies on RTX in AAV patients. We retrospectively reviewed the records of AAV patients treated with RTX following an inadequate response to immunosuppressives between 2011 and 2015. The systematic review covered all English articles listed in PubMed until June 2017. There were 25 AAV patients (21 GPA, four unclassified) treated with RTX (median 2, IQR 1-3 courses; median follow-up 24, IQR 17-50 months). The kidney and the lung were the most commonly affected organs, observed in 14 and 16 patients, respectively. Complete remission rate was 72% at month 6 and 88% at month 12. Two patients had died and three serious adverse events occurred. The systematic review included 56 studies on 1422 patients with the majority being on refractory or relapsing disease. There was wide variability regarding disease characteristics, endpoints, concomitant immunosuppressives and RTX schedule. Most studies reported > 80% complete or partial remission rates with the lowest response (37.5%) for granulomatous lesions. The relapse rate was 30%. Infections and infusion reactions were the main adverse events. Our experience with RTX in refractory AAV is in line with the literature in terms of efficacy and safety. The systematic review underlines many uncertainties on its optimal use.

Abstract
The results of a number of prospective randomized controlled clinical trials have led to changes in established strategies for the treatment of antineutrophil cytoplasmic antibody (ANCA) associated vasculitides (AAV) in recent years. Since 2014, a total of 4 scientific societies and study groups have systematically reviewed the new data and have formulated evidence-based recommendations for the management of AAV based on the analysis. These recommendations contain information on diagnosis, treatment (induction and maintenance), supportive care and monitoring of disease activity and resulting damage. This review compares the recently published recommendations of the German Society of Rheumatology (Deutschen Gesellschaft für Rheumatologie, DGRh), the European League Against Rheumatism (EULAR)/European Renal Association (ERA), the British Society of Rheumatology (BSR) and the Canadian Vasculitis Research Network (CanVasc). The comparative analysis reveals a high level of agreement on numerous topics but also shows some minor and even a few major differences in the respective recommended approach to diagnosis and treatment of AAV. Divergent recommendations predominantly exist in areas with little scientific evidence from clinical studies. Furthermore, some differences result from different interpretation of existing data or are influenced by characteristic features of the respective national healthcare system.

Abstract
PURPOSE OF REVIEW The purpose of this review is to describe the efficacy and safety of rituximab (RTX) as a remission induction and maintenance therapy in ANCA-associated vasculitis (AAV). RECENT FINDINGS A PubMed search was carried out to track down articles published between February 2006 and February 2016. Randomized controlled trials (RCTs) that encompassed patients with AAV were included. The American College of Rheumatology (ACR) and the European League against Rheumatism (EULAR) 2014-2015 online abstracts were also reviewed whether they were RTCs or not. Ten PubMed RCTs were analyzed along with eight ACR and four EULAR abstracts. RTX was not inferior to cyclophosphamide (CYC) for remission induction in AAV; it was superior to CYC in patients with relapsing disease and superior for remission maintenance in comparison with azathioprine (AZA). Rituximab is a therapeutic option to induce and maintain remission in patients with AAV.

Abstract
The prognosis of the antineutrophil cytoplasmic antibody associated vasculitides (AAV), microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA) and eosinophilic GPA (EGPA), has been fundamentally improved over the last five decades by the use of glucocorticoids and immunosuppressants, turning them from consistently fatal diseases into chronic conditions. The long-term course is now largely determined by the frequency of disease flares and by accruing damage caused by disease activity and treatment-related comorbidities. This review summarizes the evidence derived from clinical trials performed during the last 30 years and the remaining clinical unmet needs that new studies aim to address. In MPA and GPA, ongoing studies assess (i) different strategies to reduce cumulative glucocorticoid doses currently used for induction and maintenance of remission, (ii) the efficacy of new drugs and (iii) the optimal duration of immunosuppression and the use of biomarkers to individualize therapy. Prospective randomized trials also target disease-associated cardiovascular risk and infections. The first prospective controlled trials specifically designed for EGPA have recently been launched and could lead to new therapeutic options for patients diagnosed with this rare disease. This is an exciting time for researchers in the field of AAV, and for patients as collaborative efforts raise the hope of developing new therapies and more individualized approaches to the management of the diseases, maximizing efficacy while minimizing treatment toxicities.

Abstract
Limited orbital granulomatosis with polyangiitis (GPA) is uncommon and its diagnosis may be delayed, especially when isolated lacrimal involvement is the initial presentation, because clinical manifestations are non-specific and systemic diagnostic criteria are not applicable. Making an early diagnosis despite the absence of systemic progression is extremely important because in some cases the disease is locally destructive, with irreversible visual and functional loss, and it can be refractory to corticosteroids and conventional immunosuppressive drugs to induce remission. The authors report an unusual limited form of orbital GPA in a 35-year-old woman presenting with bilateral dacryoadenitis, evolving later to locally aggressive bilateral orbital pseudotumour leading to proptosis, extraocular myositis, diplopia and medial deviation of the nasal septum. She had never had systemic manifestations but her disease was persistently active and unresponsive to corticosteroids and immunosuppressors. The aim of this paper is to provide further evidence of aggressive and refractory limited forms of GPA.

Abstract
Granulomatosis with polyangiitis (GPA) is an idiopathic vasculitis of medium and small arteries, characterized by necrotizing granulomatous inflammation. GPA typically affects upper and lower respiratory tract with coexisting glomerulonephritis. This disease is generally characterized by antineutrophil cytoplasm antibodies (ANCA), nevertheless, there are rare cases with negative ANCA. GPA affects people at any age, with predominance of the sixth and seventh decade of life. In 80%-95% of the patients the first symptoms of GPA are otorhinolaryngological manifestations of head and neck including nose/sinuses, ears, eyes, larynx/trachea, oral cavity, and salivary glands. Diagnosis of GPA is based on Criteria of the American College of Rheumatology. In clinical practice diagnosis, the presence of distinctive ANCA antibodies and biopsy of affected organ are crucial. GPA must be differentiated from neoplastic, infectious or inflammatory ulcerative lesions of the head and neck. The standard treatment procedure is divided into two essential phases, induction and maintenance. The induction phase is based on combination of systemic corticosteroid and immunosuppressant therapy, whereas the maintenance phase comprises corticosteroids and azathioprine/methotrexate supplementation. Surgical treatment ought to be considered for patients who are not responding to pharmacotherapy.

Abstract
BACKGROUND Granulomatosis with polyangiitis is a rare multisystemic autoimmune disorder predominantly affecting the upper and lower respiratory tracts and the kidneys, and rarely affecting other organ systems. Tuberculosis can mimic the presentation of granulomatosis with polyangiitis, and both can occur simultaneously in the same patient. Here we report what we believe to be the first case of concurrent granulomatous breast lesions and hemorrhagic retinal angiopathy in a Sri Lankan woman with refractory granulomatosis with polyangiitis complicated by probable tuberculosis. CASE PRESENTATION A 48-year-old Sri Lankan Moorish woman presented with a 6-month history of ulcerating bilateral breast lumps, a 3-month history of non-healing painful ulcers on the palate, and sudden bilateral painless loss of vision. Retinoscopy confirmed left-sided retinal hemorrhages and bilateral panuveitis. An examination of her respiratory system showed bilateral coarse crepitations. Histologic examination of the palatal and breast lesions showed chronic granulomatous inflammation. Her levels of immune markers were elevated but her renal function was normal. Chest radiography showed bilateral mid-zone and lower-zone infiltrates with cavitation and small pleural effusions. Her serum proteinase 3 anti-neutrophil cytoplasmic antibody titer and the level of adenosine deaminase in her pleural fluid were significantly elevated. She was diagnosed with generalized granulomatosis with polyangiitis complicated with probable pulmonary tuberculosis, and was started on methylprednisolone and cyclophosphamide pulse therapy with anti-tuberculous treatment. She later developed cerebral vasculitis, indicating refractory disease, and was treated with second-line rituximab with excellent response. CONCLUSION Proteinase 3 anti-neutrophil cytoplasmic antibody may be a valuable diagnostic marker in patients with atypical symptoms of granulomatosis with polyangiitis or in the presence of probable tuberculosis. Retinal vascular angiopathy needs to be diagnosed and treated early to prevent the development of complete blindness. Concomitant cytotoxic and anti-tuberculous treatments may be safe and effective in patients with simultaneous refractory disease with probable tuberculosis.

Abstract
Reports of hypertrophic pachymeningitis associated with myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) localized exclusively in the spine were quite rare. Two cases of ANCA-associated systemic vasculitis (AASV) presenting with hypertrophic spinal pachymeningitis (HSP) causing low back pain and numbness are described. Two patients showed prominent systemic and local inflammatory reactions manifested as fever, elevated levels of erythrocyte sedimentation rate and C-reactive protein, and markedly increased levels of total protein of cerebrospinal fluid. The gadolinium (Gd)-enhanced T1-weighted magnetic resonance imaging scan of spinal cord demonstrated diffuse spinal dura matter thickening. Additionally, simple microscopic hematuria was found in 1 case suggestive of renal involvement and the other 1 complicated with interstitial lung disease. Then, a diagnosis of HSP secondary to AASV was made. Combination therapy of corticosteroids and cyclophosphamide produced a rapid improvement in the clinical symptoms and laboratory parameters. Followed up for 6 months, 1 case relapsed when the dosage of prednisone was tapered to 10 mg daily. Since the patient refused rituximab-based regimen, an immunosuppressive triple-therapy (corticosteroid, cyclophosphamide, and azathioprine) was initiated and brought control of the disease during the subsequent 6 months of follow-up.HSP is a relatively rare form of central nervous system involvement of AASV. Early recognition and intervention are of great significance since the pathogenesis of HSP starts with an inflammatory and fibrosing process.

Abstract
BACKGROUND Renal vasculitis presents as rapidly progressive glomerulonephritis which comprises of a group of conditions characterised by acute kidney injury (AKI), haematuria and proteinuria. Treatment of these conditions comprises 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 an update of a review first published in 2008. 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 Specialised Register up to 27 July 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA Randomised controlled trials investigating any intervention for the treatment of renal vasculitis in adults. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Statistical analyses were performed using a random effects model and results expressed as risk ratio (RR) with 95% confidence intervals (CI) for dichotomous outcomes or mean difference (MD) for continuous outcomes. MAIN RESULTS Thirty one studies (2217 patients) were included. Studies conducted earlier tended to have a higher risk of bias due to poor (or poorly reported) study design, broad inclusion criteria, less well developed disease definitions and low patient numbers. Later studies tend to have improved in all areas of quality, aided by the development of large transnational study groups.Plasma exchange as adjunctive therapy significantly reduces the risk of end-stage kidney disease at three months (2 studies: RR 0.43, 95% CI 0.23 to 0.78) and 12 months (6 studies: RR 0.45, 95% CI 0.29 to 0.72). Four studies (300 patients) compared the use of pulse and continuous administration of cyclophosphamide. Remission rates were equivalent but pulse treatment causes an increased risk of relapse (4 studies: RR 1.79, 95% CI 1.11 to 2.87) compared with continuous cyclophosphamide. Azathioprine has equivalent efficacy as a maintenance agent to cyclophosphamide with fewer episodes of leucopenia. Mycophenolate mofetil may be equivalent to cyclophosphamide as an induction agent but resulted in a higher relapse rate when tested against azathioprine in remission maintenance. Rituximab is an effective remission induction agent. Methotrexate or leflunomide are potential choices in remission maintenance therapy. Oral co-trimoxazole did not reduce relapses significantly in granulomatosis with polyangiitis. AUTHORS' CONCLUSIONS Plasma exchange was effective in patients with severe AKI secondary to vasculitis. Pulse cyclophosphamide results in an increased risk of relapse when compared to continuous oral use but a reduced total dose. Whilst cyclophosphamide is standard induction treatment, rituximab and mycophenolate mofetil were also effective. Azathioprine, methotrexate and leflunomide were effective as maintenance therapy. Further studies are required to more clearly delineate the appropriate place of newer agents within an evidence-based therapeutic strategy.

Abstract
OBJECTIVE Nonsevere relapses are more common than severe relapses in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but their clinical course and treatment outcomes remain largely unexamined. We undertook this study to analyze the outcomes of patients with nonsevere relapses in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial who were treated with prednisone according to a prespecified protocol. METHODS RAVE was a randomized, double-blind, placebo-controlled trial comparing rituximab (RTX) to cyclophosphamide (CYC) followed by azathioprine (AZA) for induction of remission. Patients who experienced nonsevere relapses between months 1 and 18 were treated with a prednisone increase without a concomitant change in their nonglucocorticoid immunosuppressants, followed by a taper. RESULTS Forty-four patients with a first nonsevere relapse were analyzed. In comparison to the 71 patients who maintained relapse-free remission over 18 months, these patients were more likely to have proteinase 3-ANCAs, diagnoses of granulomatosis with polyangiitis (Wegener's), and a history of relapsing disease at baseline. A prednisone increase led to remission in 35 patients (80%). However, only 13 patients (30%) were able to maintain second remissions through the followup period (mean 12.5 months); 31 patients (70%) had a second disease relapse, 14 of them with severe disease. The mean time to second relapse was 9.4 months (4.7 months in the group treated with RTX versus 13.7 months in the group treated with CYC/AZA; P < 0.01). Patients who experienced nonsevere relapses received more glucocorticoids than those who maintained remission (6.7 grams versus 3.8 grams; P < 0.01). CONCLUSION Treatment of nonsevere relapses in AAV with an increase in glucocorticoids is effective in restoring temporary remission in the majority of patients, but recurrent relapses within a relatively short interval remain common. Alternative treatment approaches are needed for this important subset of patients.

Abstract
ANCA-associated vasculitides (AAV) are chronic autoimmune diseases characterized by inflammation and destruction of small vessels. Rituximab is now licensed for use as a remission-induction agent in the treatment of these disorders. During recent years, several non-controlled studies have suggested that rituximab may be of value in maintaining disease remission in AAV. In these series, 3 techniques have been tried: "watch-and-wait", repeated cycles in fixed intervals, or administration based on proposed biomarkers. More importantly, the results of the MAINRITSAN trial showed that this anti-CD20 agent is superior to azathioprine for preventing major relapses in AAV. This review summarizes current information regarding the effectiveness, timing, dosing, duration and safety of rituximab as a valid option for remission maintenance.

Abstract
BACKGROUND Recent data from randomized controlled clinical trials have allowed the development of recommendations for treatment of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides (AAV). METHODS A selective literature search was carried out for studies and recommendations for treatment of AAV. RESULTS In active severe AAV a combination of prednisolone and cyclophosphamide or rituximab leads to a therapeutic response in approximately 90 % of cases. Once remission is attained the administration of azathioprine or methotrexate for 2-4 years is required for maintenance of remission. Relapse occurs in more than 30 % of patients despite maintenance treatment. In cases of persistence or progression of disease activity during standard therapy, referral to an expert center should be considered. Despite improvement in the prognosis in recent years early mortality is increased, particularly due to infections. CONCLUSION Stage and activity adapted treatment strategies have improved the outcome of AAV in the past three decades. The elevated early mortality and the risk of relapse show the need for further improvement of current treatment protocols with respect to substance selection, dosage of glucocorticoids and immunosuppressants and the duration of therapy.

Abstract
The introduction of glucocorticoids and cyclophosphamide has transformed ANCA associated vasculitis (AAV) from a fatal to a largely treatable condition. Over the past 40 years, considerable progress has been made in refining immunosuppressive regimens with a focus on minimising toxicity. As knowledge of the pathogenesis of AAV grows, it is mirrored by the availability of biological agents. Lymphocyte and cytokine targeted agents have been evaluated for the treatment of AAV and are entering the routine therapeutic arena with the potential to improve patient outcomes. Rituximab has transformed management of AAV in the past decade. However, there remains unmet need in the treatment of AAV; the majority of patients will relapse within five years of diagnosis despite maintenance immunosuppression; a small number of patients remain refractory to current therapies and treatment toxicity continues to contribute to mortality and chronic disability. As in rare diseases, treatment advances in vasculitis depend on international collaborative research networks to both establish an evidence base for newer agents and develop recommendations for optimal patient management.

Abstract
Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the accumulation of surfactant-like lipoproteinaceous material in the distal air spaces and terminal bronchi, which may lead to impaired gas exchange. This accumulation of surfactant is due to decreased clearance by the alveolar macrophages. Its primary, most common form, is currently considered an autoimmune disease. Better knowledge of the causes of PAP have led to the emergence of alternatives to whole lung lavage, although this is still considered the treatment of choice. Most studies are case series, often with limited patient numbers, so the level of evidence is low. Since the severity of presentation and clinical course are variable, not all patients will require treatment. Due to the low level of evidence, some objective criteria based on expert opinion have been arbitrarily proposed in an attempt to define in which patients it is best to initiate treatment.
