Abstract
INTRODUCTION Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare but potentially lethal systemic vasculitis. Only a few prospective therapeutic trials had been conducted in EGPA, and its treatment was mostly adapted from other vasculitides. Monoclonal antibodies inhibiting various pathways (e.g. interleukin-5 [IL5] or B cells) have been investigated. AREAS COVERED Published studies on treatments for EGPA using glucocorticoids, conventional immunosuppressants (such as cyclophosphamide or azathioprine), antiIL5 pathway agents (mepolizumab, approved by the Food and Drug Administration (FDA) and European Medicines Agency (EMA) for EGPA; benralizumab and reslizumab), other and future possible treatments [PubMed search, 01/1990-02/2023] are reviewed. EXPERT OPINION With advances made in the pharmacotherapeutic management of EGPA, the prognosis has gradually shifted from a potentially fatal to a more chronic course, for which more targeted and safer treatments can be used. However, glucocorticoids remain central. Rituximab is now a possible alternative to cyclophosphamide for induction, although data are still limited. AntiIL5 pathway therapies have been shown to be safe and effective in relapsing patients with EGPA, who often experience asthma and/or ears, nose, and throat (ENT) manifestations, but long-term data are needed. Treatment strategies need to be optimized based on individual patient characteristics, likely with sequential, combination-based approaches, while topical airway treatments should not be forgotten.

Abstract
The eosinophilic lung diseases may manifest as chronic eosinophilic pneumonia, acute eosinophilic pneumonia, or as the Löffler syndrome (generally of parasitic etiology). The diagnosis of eosinophilic pneumonia is made when both characteristic clinical-imaging features and alveolar eosinophilia are present. Peripheral blood eosinophils are generally markedly elevated; however, eosinophilia may be absent at presentation. Lung biopsy is not indicated except in atypical cases after multidisciplinary discussion. The inquiry to possible causes (medications, toxic drugs, exposures, and infections especially parasitic) must be meticulous. Idiopathic acute eosinophilic pneumonia may be misdiagnosed as infectious pneumonia. Extrathoracic manifestations raise the suspicion of a systemic disease especially eosinophilic granulomatosis with polyangiitis. Airflow obstruction is frequent in allergic bronchopulmonary aspergillosis, idiopathic chronic eosinophilic pneumonia, eosinophilic granulomatosis with polyangiitis, and hypereosinophilic obliterative bronchiolitis. Corticosteroids are the cornerstone of therapy, but relapses are common. Therapies targeting interleukin 5/interleukin-5 are increasingly used in eosinophilic lung diseases.

Abstract
OBJECTIVE To analyse the available evidence about the use of rituximab (RTX) and other biologic agents in eosinophilic granulomatosis with polyangiitis (EGPA) patients and to provide useful findings to inform the design of future, reliable clinical trials. METHODS A systematic review was performed. A systematic search was conducted in PubMed/MEDLINE, Scopus, Web of Science and the Cochrane library databases on RTX, and an extensive literature search was conducted on other biologic agents. RESULTS Forty-five papers pertinent to our questions were found: 16 retrospective cohort studies, 8 case series, 3 prospective cohort studies and 18 single case reports, for a total of 368 EGPA patients. More than 80% of evaluable patients achieved complete or partial remission with a tendency towards a higher rate of complete response in the pANCA-positive subgroup. CONCLUSION Although the majority of the evaluable EGPA patients treated with RTX appears to achieve complete remission, we strongly believe that a number of sources of heterogeneity impair a clear interpretation of results and limit their transferability in clinical practice. Differences in design, enrolment criteria, outcome definition and measurement make a comparison among data obtained from studies on RTX and other biologic agents unreliable.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA, formerly Churg-Strauss syndrome) is the least frequent antineutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). Major advances of our knowledge on its pathophysiology have revealed features of both AAV and eosinophilic disorders. The development of targeted biotherapies for both diseases opened new possibilities for EGPA management. In this review, we highlight the rationale underlying the routine treatment strategy, which relies mainly on corticosteroids, with immunosuppressant adjunction for severe disease. However, novel therapies are still needed for refractory/relapsing disease and to alleviate the corticosteroid-dependence of asthma and chronic rhinosinusitis. At present, the most promising biotherapies target either eosinophil biology, like mepolizumab, an anti-interleukin-5, or the B-cell compartment, with rituximab. Recent clinical data on new treatment options are discussed and therapeutic strategies are proposed.

Abstract
For the treatment of eosinophilic granulomatosis with polyangiitis (EGPA) much less data are available when compared to the other anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV). At the same time EGPA also differs in many aspects from AAVs. Treatment is guided by the German and international guidelines. An adapted induction therapy is chosen depending on the disease activity, manifestations and factors determining the prognosis. For patients without negative prognostic factors glucocorticoids alone may be sufficient. A medium potent immunosuppressive agent may be added in order to economize on steroids. For patients with severe organ manifestations and adverse prognostic factors, a highly potent immunosuppression usually with cyclophosphamide, is necessary. In cases of remission a maintenance therapy is recommended in the same way as for other AAVs. Recently, a biological, the IL-5 antibody mepolizumab has also become available, although its precise role still has to be established.

Abstract
INTRODUCTION Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis characterized by asthma, hypereosinophilia, and progressive multiorgan involvement. Although not fully elucidated, advancement in our understanding of the pathophysiology of EGPA has led to the development of multiple new treatment targets. AREAS COVERED Herein we review the epidemiology, clinical manifestations, pathophysiology, treatments, and ongoing research in the management of EGPA. The central role of Interleukin-5 (IL-5) in the development and maintenance of hypereosinophilia will be discussed. The value of mepolizumab, an anti-IL-5 monoclonal antibody, in the treatment of EGPA is reviewed in detail. EXPERT OPINION The available literature supports the use of mepolizumab for the induction and maintenance of remission of refractory, relapsing, or glucocorticoid-dependent EGPA with potentially greater benefit in those who are ANCA-positive or those with greater eosinophilia ( ≥ 150 cells/ μ L). Despite these positive results, relapses remain frequent, and the need for both short- and long-term glucocorticoid use remains common. More research is needed to address these needs and determine the precise role of mepolizumab.

Abstract
Eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) is a rare type of anti-neutrophil cytoplasm antibody-associated vasculitis. Nevertheless, eosinophilic granulomatosis with polyangiitis stands apart because it has features of vasculitis and eosinophilic disorders that require targeted therapies somewhat different from those used for other anti-neutrophil cytoplasm antibody-associated vasculitides. Considerable advances have been made in understanding the underlying pathophysiology of eosinophilic granulomatosis with polyangiitis that have highlighted the key role of eosinophils and opened new therapeutic opportunities. Its conventional treatment relies mainly on agents that decrease inflammation: corticosteroids and immunosuppressant adjunction for severe manifestations. New therapeutic approaches are needed for refractory disease, relapses and issues associated with corticosteroid dependence, especially for asthma manifestations. Drugs under evaluation mostly target eosinophils and B cells. Results of low-evidence-based trials suggested possible efficacies of biologicals: B-cell-blocking rituximab and anti-immunoglobulin E omalizumab. Recently, the first large-scale randomised controlled trial on eosinophilic granulomatosis with polyangiitis proved the efficacy of anti-interleukin-5 mepolizumab. That finding opens a new era in eosinophilic granulomatosis with polyangiitis management, with mepolizumab approval but also in future drug evaluations and trial designs for eosinophilic granulomatosis with polyangiitis. Additional studies are needed to determine which patients would benefit most from targeted therapies and achieve personalised treatment for patients with eosinophilic granulomatosis with polyangiitis. Herein, we review eosinophilic granulomatosis with polyangiitis characteristics and provide an overview of established and novel pharmacological agents.

Abstract
Despite the progress in the last years on the field of vasculitides, there are several unmet needs regarding classification, disease activity assessment, predictors of flares and complications, and type of treatment for the different forms. The 1990 American College of Rheumatology (ACR) classification criteria currently used to define giant cell arteritis and Takayasu arteritis were designed to discriminate between different types of vasculitides but not to differentiate vasculitis from other disorders. Recently, efforts have been made to overcome the shortcomings of the ACR criteria. The lack of an accepted definition of disease activity in large-vessel vasculitides presents a major challenge in creating useful and valid outcome tools for the assessment of disease course. Identification of predictors of flares can aid in optimizing therapeutic strategies, minimizing disease flares, and reducing treatment-related side effects. It is furthermore important to recognize and characterize the risk factor that might predict the manifestations associated with poor outcome and prognosis. Two RCTs have evidenced the efficacy of tocilizumab in addition to glucocorticoids (GCs) in the treatment of giant cell arteritis (GCA). However, the role of tocilizumab or other biological agents without GCs needs to be investigated. Recent observational studies have suggested that rituximab is also effective in patients with eosinophilic granulomatosis with polyangiitis and in antineutrophil cytoplasmic antibodies (ANCA)-negative patients with granulomatosis with polyangiitis and microscopic polyangiitis. Rituximab or anti-TNF alfa may represent a possible alternative therapy in case of refractory or difficult to treat polyarteritis nodosa (PAN) patients. The new International Criteria for Behçet's Disease have shown a better sensitivity and a better accuracy compared to the older International Study Group on Behçet's Disease criteria. The EULAR recommendations for the management of Behçet's disease (BD) have been recently updated. However, the treatment of refractory disease is still a real challenge.

Abstract
Pembrolizumab, an anti-programmed death-1 monoclonal antibody, has been approved by the Food and Drug Administration in 2014 on the basis of improved progression-free and overall survival in metastatic melanoma. We report for the first time a successful treatment with a programmed death-1 antibody in a 69-year-old metastastic melanoma patient with a Churg-Strauss lung vasculitis and a prior ipilimumab-induced autoimmune colitis. This case report suggests that pembrolizumab can be given with caution to patients with underlying autoimmune disease. As the use of checkpoint inhibitors expands, knowledge about their safety in patients with underlying autoimmune diseases will become increasingly important, in particular because these patients are typically excluded from clinical trials with immune-checkpoint inhibitors.

Abstract
Eosinophilic lung diseases especially comprise eosinophilic pneumonia or as the more transient Löffler syndrome, which is most often due to parasitic infections. The diagnosis of eosinophilic pneumonia is based on characteristic clinical-imaging features and the demonstration of alveolar eosinophilia, defined as at least 25% eosinophils at BAL. Peripheral blood eosinophilia is common but may be absent at presentation in idiopathic acute eosinophilic pneumonia, which may be misdiagnosed as severe infectious pneumonia. All possible causes of eosinophilia, including drug, toxin, fungus related etiologies, must be thoroughly investigated. Extrathoracic manifestations should raise the suspicion of eosinophilic granulomatosis with polyangiitis.

Abstract
INTRODUCTION The prevalence of eosinophilic granulomatosis with polyangiitis (EGPA; previously known as Churg-Strauss syndrome) is lower than that of other antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV's), and only a few randomized controlled trials have been conducted for this rare disease. However, recent international efforts have helped delineate the best treatment approach. AREAS COVERED At present, EGPA conventional therapy is by default similar to that of other AAVs. Limited, non-severe EGPA can initially be treated with glucocorticoids (GCs) alone. Patients with life-threatening manifestations and/or major organ involvement must receive a combination of GCs and an immunosuppressant, mainly cyclophosphamide. Remission can be achieved in >85% of patients with these first-line treatments, but vasculitis relapses occur in more than one-third of patients, and about 85% cannot stop GC treatment because of GC-dependent asthma and/or ENT manifestations. A few biologic agents, including rituximab or mepolizumab, are now under investigation after interesting preliminary results. Expert commentary: Treatment for EGPA still has several unmet needs. Several biologic agents are now under investigation in randomized controlled trials, but a few others should be considered soon. Their benefit should be demonstrated for devising more EGPA-tailored therapeutic strategies (ideally GC-free).

Abstract
OBJECTIVE To develop disease-specific recommendations for the diagnosis and management of eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome) (EGPA). METHODS The EGPA Consensus Task Force experts comprised 8 pulmonologists, 6 internists, 4 rheumatologists, 3 nephrologists, 1 pathologist and 1 allergist from 5 European countries and the USA. Using a modified Delphi process, a list of 40 questions was elaborated by 2 members and sent to all participants prior to the meeting. Concurrently, an extensive literature search was undertaken with publications assigned with a level of evidence according to accepted criteria. Drafts of the recommendations were circulated for review to all members until final consensus was reached. RESULTS Twenty-two recommendations concerning the diagnosis, initial evaluation, treatment and monitoring of EGPA patients were established. The relevant published information on EGPA, antineutrophil-cytoplasm antibody-associated vasculitides, hypereosinophilic syndromes and eosinophilic asthma supporting these recommendations was also reviewed. DISCUSSION These recommendations aim to give physicians tools for effective and individual management of EGPA patients, and to provide guidance for further targeted research.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare eosinophil-rich disorder characterised by necrotising granulomatous inflammation affecting small to medium sized vessels. Extrapulmonary manifestations can be life-threatening when heart, central nervous system (CNS), gastrointestinal tract or kidneys are affected. We describe a case of a 56-year-old woman with a long-standing history of asthma, who presented with an acute sudden painless loss of vision after she had been recently diagnosed with EGPA and induced with pulse steroids and cyclophosphamide. The patient had a complicated hospital course with multisystemic involvement of active vasculitis, involving heart, kidneys, muscles, eyes and CNS. The patient's devastating condition responded remarkably to Rituximab. The role of Rituximab in EGPA is not yet proven. Few cases are reported in the literature about the role of Rituximab in EGPA, of which only one described retinal artery occlusion as a presentation of a recently treated patient with EGPA.

Abstract
The anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides granulomatosis with polyangiitis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA) and microscopic polyangiitis (MPA) constitute a wide spectrum of clinical manifestations of systemic vasculitis which may range from limited disease to organ or life-threatening disease. The introduction of biologics for the management of severe ANCA-associated vasculitis and severe, relapsing disease refractory to conventional immunosuppressants, has significantly improved the clinical prognosis of these autoimmune disorders. Rituximab, an anti-CD20 monoclonal antibody is licenced for remission induction in severe GPA and MPA and the management of severe relapsing, refractory GPA and MPA. Belimumab, an anti-B lymphocyte stimulatory monoclonal antibody is in clinical trials for the management of the ANCA-associated vasculitis GPA. Mepolizumab and Omalizumab are biologics which have been reported to be efficacious in refractory asthma associated with EGPA. The role of anti-TNF therapy and T cell targeting drugs in ANCA-associated vasculitis is less clear due to limited study data. This review will summarise the clinical trials and clinical practice use of biologic treatment strategies for the management of ANCA-associated vasculitis.

Abstract
OBJECTIVE Rituximab is approved for the treatment of granulomatosis with polyangiitis and microscopic polyangiitis. Our objective was to review published clinical evidence on the efficacy of rituximab in the treatment of eosinophilic granulomatosis and polyangiitis (EGPA). METHODS We describe a case of refractory EGPA with severe vasculitic neuropathy, which responded impressively to B-cell-depleting therapy. A systematic search of the English literature was also performed to capture all available clinical evidence on the use of rituximab in EGPA. RESULTS We identified a total of 73 EGPA patients who have been treated with rituximab, all data coming from case series or isolated case reports. The majority of patients (85.1%) were treated for refractory or relapsing disease; a mean (SD) of 2.1 (0.9) different immunosuppressive agents were used prior to rituximab administration. Efficacy of RTX therapy was significant in the majority of cases and in a wide variety of disease manifestations; however, a lack of standardized assessment of disease activity before and after treatment was observed in many reports. Overall, 54.0% of patients were treated with a single cycle of rituximab and only 10.8% experienced relapses of the disease. Few significant side effects were observed during a highly variable period of follow-up (3 months to 5 years), mainly severe infections and allergic reactions. CONCLUSIONS RTX seems to be effective in cases of severe EGPA refractory to standard of care immunosuppressive treatment, although support comes from case reports and non-controlled studies.

Abstract
BACKGROUND The general consensus is that for patients with EGPA with poor prognosis, intensive therapy with both GC and CF is indicated. The maintenance of remission is made with GC and AZA. A considerable number of patients with EGPA are refractory to first line therapy, experience dose-limiting side effects or relapse. In clinical trials, RTX was effective for the treatment of ANCA-associated vasculitis. However, patients with a diagnosis of EGPA were not included. OBJECTIVE to review and analyze the published literature regarding the use of RTX in the treatment of EGPA. METHODS The literature search was performed in MEDLINE and LILACS from 1965 and 1986 respectively until february 2014. RESULTS 27 patients were included. RTX treatment was due to refractory disease (n=20), relapse (n=5) and with newly diagnosed (n=2). The affected organs were the lungs, peripheral nervous system, kidney and the eyes. Sixteen patients had clinical remission and 8 patients had clinical response. CONCLUSIONS RTX was effective and well tolerated for the treatment of EGPA.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic disorder, belonging to the small vessel anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, defined as an eosinophil-rich and necrotizing granulomatous inflammation often involving the respiratory tract, and necrotizing vasculitis predominantly affecting small to medium-sized vessels, associated with asthma and eosinophilia. EGPA pathogenesis is not well known: HLA-DRB1*04 and *07, HLA-DRB4 and IL10.2 haplotype of the IL-10 promoter gene are the most studied genetic determinants. Among the acquired pathogenetic factors, the exposure to different allergens, infections, vaccinations, drugs, and silica exposure have been involved. Eosinophils are the most characteristic cells in EGPA and different studies have demonstrated their role as effector and immunoregulatory cells. EGPA is considered as a disease with a prevalent activation of the Th-2 cellular-mediated inflammatory response and also humoral immunity plays an important role. A link between B and T inflammatory responses may explain different disease features. EGPA typically develops into three sequential phases: the allergic phase, distinguished by the occurrence of asthma, allergic rhinitis, and sinusitis, the eosinophilic phase, in which the main pathological finding is the eosinophilic organ infiltrations (e.g., lungs, heart, and gastrointestinal system), and the vasculitic phase, characterized by purpura, peripheral neuropathy, and constitutional symptoms. ANCA (especially pANCA anti-myeloperoxidase) are present in 40-60% of the patients. An elevation of IgG4 is frequently found. Corticosteroids and cyclophosphamide are classically used for remission induction, while azathioprine and methotrexate are the therapeutic options for remission maintenance. B-cell depletion with rituximab has shown promising results for remission induction.

Abstract
BACKGROUND Central disinhibition is a mechanism involved in the physiopathology of fibromyalgia. Melatonin can improve sleep quality, pain and pain threshold. We hypothesized that treatment with melatonin alone or in combination with amitriptyline would be superior to amitriptyline alone in modifying the endogenous pain-modulating system (PMS) as quantified by conditional pain modulation (CPM), and this change in CPM could be associated with serum brain-derived neurotrophic factor (BDNF). We also tested whether melatonin improves the clinical symptoms of pain, pain threshold and sleep quality. METHODS Sixty-three females, aged 18 to 65, were randomized to receive bedtime amitriptyline (25 mg) (n = 21), melatonin (10 mg) (n = 21) or melatonin (10 mg) + amitriptyline (25 mg) (n = 21) for a period of six weeks. The descending PMS was assessed with the CPM-TASK. It was assessed the pain score on the Visual Analog Scale (VAS 0-100 mm), the score on Fibromyalgia Impact Questionnaire (FIQ), heat pain threshold (HPT), sleep quality and BDNF serum. Delta values (post- minus pre-treatment) were used to compare the treatment effect. The outcomes variables were collected before, one and six weeks after initiating treatment. RESULTS Melatonin alone or in combination with amitriptyline reduced significantly pain on the VAS compared with amitriptyline alone (P < 0.01). The delta values on the VAS scores were-12.85 (19.93),-17.37 (18.69) and-20.93 (12.23) in the amitriptyline, melatonin and melatonin+amitriptyline groups, respectively. Melatonin alone and in combination increased the inhibitory PMS as assessed by the Numerical Pain Scale [NPS(0-10)] reduction during the CPM-TASK:-2.4 (2.04) melatonin + amitriptyline,-2.65 (1.68) melatonin, and-1.04 (2.06) amitriptyline, (P < 0.05). Melatonin + amitriptyline treated displayed better results than melatonin and amitriptyline alone in terms of FIQ and PPT improvement (P < 0.05, fort both). CONCLUSION Melatonin increased the inhibitory endogenous pain-modulating system as assessed by the reduction on NPS(0-10) during the CPM-TASK. Melatonin alone or associated with amitriptyline was better than amitriptyline alone in improving pain on the VAS, whereas its association with amitriptyline produced only marginal additional clinical effects on FIQ and PPT.

Abstract
Prior to the 1970s, severe cases of antineutrophil cytoplasmic antibody associated vasculitis (AAV) were thought to be invariably fatal. However, the use of cyclophosphamide-based treatment regimens fundamentally altered disease outcomes, transforming AAV into a manageable, chronic illness. Despite the tremendous success of cyclophosphamide in the treatment of AAV, there remained a need for alternative therapies, due to high rates of treatment failures and significant toxicities. In recent years, with the introduction of targeted biologic response modifiers into clinical practice, many have hoped that the treatment options for AAV could be expanded. Rituximab, a chimeric monoclonal antibody directed against the B-lymphocyte protein CD20, has been the most successful biologic response modifier to be used in AAV. Following the first report of its use in AAV in 2001, experience with rituximab for treatment of AAV has rapidly expanded. Rituximab, in combination with glucocorticosteroids, is now well established as a safe and effective alternative to cyclophosphamide for remission induction for severe manifestations of granulomatosis with polyangiitis and microscopic polyangiitis. In addition, initial experiences with rituximab for remission maintenance in these diseases have been favorable, as have experiences for remission induction in eosinophilic granulomatosis with polyangiitis.

Abstract
ANCA-associated vasculitis (AAV) is a subgrouping of autoimmune disorders characterized by a chronic relapsing course. Induction therapy is usually effective, but 70% of patients will relapse and 20% develop refractory disease. In the relapsing and refractory subgroups, treatment is complicated by the cumulative exposure to toxic drugs that contribute to poor long-term outcomes. The anti-CD20 monoclonal antibody rituximab (RTX) depletes B cells, and the success of this targeted therapy has contributed to the evidence supporting a central role for B cells in AAV pathogenesis. Initial proof of RTX effectiveness originated from small, prospective trials and retrospective surveys conducted in AAV patients with relapsing and refractory disease; high remission rates permitted the reduction of glucocorticoids (GCS) doses and withdrawal of immunosuppressives. There has been controversy over the effectiveness of RTX in patients with predominantly granulomatous manifestations, where response rates have varied between studies, in part due to different RTX dosing regimens. These studies were followed by comparison of RTX against cyclophosphamide (CYC) for remission induction of new or relapsing AAV in two randomized trials, which led to the licensing of RTX for this indication. Subsequent attention has been turned to the use of RTX as a relapse prevention agent, to the potential for GCS sparing and to RTX-associated toxicity. We will discuss the impact that the results of RTX clinical trials have had on the management of AAV patients.

Abstract
Increasing rituximab prescription for ANCA-associated necrotizing vasculitides justifies the publication of recommendations for clinicians. Rituximab is approved in the United States to induce and maintain remission. In Europe, rituximab was recently approved for remission induction. However, governmental agencies' approvals cannot replace clinical practice guidelines. Herein, the French Vasculitis Study Group Recommendations Committee, comprised of physicians with extensive experience in the treatment of vasculitides, presents its consensus guidelines based on literature analysis, the results of prospective therapeutic trials and personal experience.

Abstract
Introduction Eosinophilic granulomatosis with polyangiitis (EGPA) is part of antineutrophil cytoplasmic antibodies (ANCAs)-associated vasculitides. In EGPA small-vessel vasculitis is associated with eosinophilia and asthma. About 40% of EGPA patients are ANCA-positive, suggesting a role for B cells in the pathogenesis of EGPA. B cell-depleting therapy with rituximab (RTX) can be effective in ANCA-positive EGPA, but very few patients have been published to date. The role of RTX in the treatment of ANCA-negative EGPA is unclear. Methods We report a single-center cohort of patients with eosinophilic granulomatosis with polyangiitis. Of these patients, nine (six ANCA-positive, three ANCA-negative) had been treated with RTX for relapsing or refractory disease on standard immunosuppressive treatment. In a retrospective analysis, data on treatment response, frequency of relapses, adverse events, and peripheral B-cell reconstitution were evaluated. Furthermore, serum immunoglobulin concentrations, ANCA status, and peripheral B cell subpopulations were assessed after RTX treatment. Results All patients had high disease activity before RTX treatment. At presentation 3 months after RTX therapy, all ANCA-positive and ANCA-negative patients had responded to RTX, with one patient being in complete remission, and eight patients being in partial remission. After a mean follow-up of 9 months, C-reactive protein concentrations had normalized, eosinophils had significantly decreased, and prednisone had been tapered in all patients. In all patients, RTX therapy was combined with a standard immunosuppressive therapy. Within the 9-month observation period, no relapse was recorded. Three patients were preemptively retreated with RTX, and during the median follow-up time of 3 years, no relapse occurred in these patients. During the follow-up of 13 patient-years, five minor but no major infections were recorded. Conclusions In our analysis on nine patients with EGPA resistant to standard therapy, rituximab proved to be an efficient and safe treatment for ANCA-positive and ANCA-negative patients. Preemptive retreatment with RTX, combined with standard maintenance immunosuppressants, resulted in a sustained treatment response. Prospective, randomized trials evaluating the use of RTX in EGPA are warranted.

Abstract
The Churg-Strauss syndrome (CSS) is the rarest subtype of the so-called anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) and has the lowest frequency of ANCA-positivity (around 30%). In addition to asthma and blood eosinophilia, CSS is characterized by end-organ damage, which can be caused by either vasculitis and/or tissue infiltration of eosinophilic granulocytes. The CSS shares many etiological and clinical features of other hypereosinophilic syndromes. Recently, a distinct genetic background could be demonstrated for both the ANCA-positive and ANCA-negative subtypes of CSS as compared to the other two forms of AAV. Among other cytokines, interleukin-5 (IL-5) could be identified as a key mediator of eosinophilia. Therefore, recent clinical trials in CSS aimed to target IL-5. Outside of clinical trials, treatment of CSS is adapted to disease stage and activity, as recommended for other types of AAV.

Abstract
Eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA) is a systemic small-vessel vasculitis associated with asthma and eosinophilia. Histology of EGPA shows tissue eosinophilia, necrotizing vasculitis, and eosinophil-rich granulomatous inflammation. EGPA commonly presents with upper airway tract and lung involvement, peripheral neuropathy, cardiac and skin lesions. Antineutrophil cytoplasmic antibodies (ANCA) are positive in ~40% of the cases and more often in patients with clinical manifestations due to small-vessel vasculitis. The pathogenesis of EGPA is multifactorial: the disease can be triggered by exposure to allergens or drugs, but a genetic background has also been recognized, particularly an association with HLA-DRB4. Th2 responses are prominent, with up-regulation of IL-4, IL-13, and IL-5; however, Th1 and Th17 responses are not negligible. Eosinophils are activated, have a prolonged lifespan and probably cause tissue damage by releasing their granule proteins; their tissue recruitment can be regulated by chemokines such as eotaxin-3 and CCL17. Humoral immunity is also dysregulated, as demonstrated by prominent IgG4 and IgE responses. EGPA promptly responds to glucocorticoid therapy, although combinations of glucocorticoids and immunosuppressants (e.g., cyclophosphamide, azathioprine) are eventually required in most cases. Newer therapeutic options include the anti-IL5 antibody mepolizumab, whose efficacy has been described in small clinical trials, and the B-cell-depleting agent rituximab, reported in several case series.

Abstract
Allergic diseases of the lungs may affect the airways, the pulmonary parenchyma and the pulmonary vessels. The most relevant representatives are allergic asthma, hypersensitivity pneumonitis, bronchopulmonary aspergillosis and the Churg-Strauss syndrome. The type of allergic reaction and the pathophysiological consequences vary considerably between these entities. New drugs target specific mechanisms based on new insights into the pathogenetic processes of the underlying disease.

Abstract
PURPOSE OF REVIEW To review the present knowledge about the use of rituximab (RTX) in patients with granulomatosis with polyangiitis (Wegener's; GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (Churg-Strauss; EGPA), also collectively referred to as antineutrophil cytoplasmic antibody-associated vasculitis. RECENT FINDINGS More than 20 case series and cohort studies involving more than 200 patients focusing on RTX use for patients with refractory GPA and MPA have been reported. Two randomized controlled trials have shown that RTX is not inferior to cyclophosphamide (CYC) for induction of remission in severe GPA and MPA. The RAVE trial has further shown that RTX is superior to CYC for patients with severe disease relapses. In addition, reports are emerging on the use of RTX for remission maintenance in chronically relapsing patients. There are also preliminary reports on the beneficial use of RTX in eosinophilic granulomatosis with polyangiitis (Churg-Strauss). SUMMARY RTX is the first proven alternative to CYC for remission induction in severe GPA and MPA. RTX is the preferred agent for patients presenting with severe disease flares, and its use had become the de facto standard of care for patients with chronically relapsing refractory GPA. Its use in EGPA requires further investigation.

Abstract
PURPOSE OF REVIEW Churg-Strauss syndrome (CSS) has a clear clinical phenotype but its pathogenesis is not fully elucidated. Recent studies have focused on its immunogenetic aspects and cytokine and chemokine-mediated pathogenetic mechanisms, providing the rationale for the use of newer targeted therapies. This study will review recent findings on the pathogenesis of CSS and its therapeutic approaches. RECENT FINDINGS CSS is usually considered a Th2-mediated disease, but Th1 and Th17 responses might also play a role; the reported association between CSS and HLA-DRB4 further underlines the pathogenetic relevance of CD4 T cells which, thanks to their ability to secrete cytokines such as IL4, IL5, and IL13, promote allergic and eosinophilic reactions. Resident cells such as endothelial and epithelial cells might also amplify the immune response by producing eosinophil-attracting chemokines such as eotaxin-3 and CCL17. Conventional immunosuppressive therapies offer high chances of achieving sustained remission, but steroid exposure remains high. Targeting IL5 with mepolizumab seems promising in sparing steroids, but relapses often follow its withdrawal. B-cell depletion using rituximab has proved effective in refractory CSS cases. SUMMARY Current knowledge on CSS pathogenesis is evolving; the identification of key molecular mechanisms will pave the way for newer, more specific treatments.

Abstract
Rheumatoid arthritis (RA) is an immune-mediated disease involving chronic low-grade inflammation that may progressively lead to joint destruction, deformity, disability and even death. Despite its predominant osteoarticular and periarticular manifestations, RA is a systemic disease often associated with cutaneous and organ-specific extra-articular manifestations (EAM). Despite the fact that EAM have been studied in numerous RA cohorts, there is no uniformity in their definition or classification. This paper reviews current knowledge about EAM in terms of frequency, clinical aspects and current therapeutic approaches. In an initial attempt at a classification, we separated EAM from RA co-morbidities and from general, constitutional manifestations of systemic inflammation. Moreover, we distinguished EAM into cutaneous and visceral forms, both severe and not severe. In aggregated data from 12 large RA cohorts, patients with EAM, especially the severe forms, were found to have greater co-morbidity and mortality than patients without EAM. Understanding the complexity of EAM and their management remains a challenge for clinicians, especially since the effectiveness of drug therapy on EAM has not been systematically evaluated in randomized clinical trials.

Abstract
Presentation of the Nephrology Quiz and Questionnaire (NQQ) has become an annual "tradition" at the meetings of the American Society of Nephrology. It is a very popular session judged by consistently large attendance. Members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. They can also compare their answers in real time, using audience response devices, to those of program directors of nephrology training programs in the United States, acquired through an Internet-based questionnaire. As in the past, the topics covered were transplantation, fluid and electrolyte disorders, end-stage renal disease and dialysis, and glomerular disorders. Two challenging cases representing each of these categories along with single best answer questions were prepared by a panel of experts (Drs. Hricik, Palmer, Bargman, and Fervenza, respectively). The "correct" and "incorrect" answers then were briefly discussed, after the audience responses and the results of the questionnaire were displayed. The 2010 version of the NQQ was exceptionally challenging, and the audience, for the first time, gained a better overall correct answer score than the program directors, but the margin was small. Last month we presented the transplantation and fluid and the electrolyte cases; in this issue we present the remaining end-stage renal disease and dialysis and the glomerular disorder cases. These articles try to recapitulate the session and reproduce its educational value for a larger audience--that of the readers of the Clinical Journal of the American Society of Nephrology. Have fun.

Abstract
Interstitial lung disease (ILD) is an increasingly recognized complication of rheumatoid arthritis (RA) contributing to significantly increased morbidity and mortality. Diagnosis can be challenging since patients are unlikely to report dyspnea due to an overall decrease in physical activity with advanced arthritic symptoms. Additionally, infections, drug toxicity, and environmental toxins can mimic ILD, creating significant diagnostic dilemmas for the clinician. In this paper we will explore an effective clinical algorithm for the diagnosis of RA-ILD. We will also discuss features of drug-related toxicities, infections, and environmental toxins that comprise the main entities in the differential diagnosis of RA-ILD. Finally, we will explore the known and experimental treatment options that may have some benefit in the treatment of RA-ILD.

Abstract
INTRODUCTION Churg-Strauss syndrome (CSS) is a small vessel systemic vasculitis associated with asthma and eosinophilia that causes glomerulonephritis (GN) in ∼25% of patients. Rituximab (RTX) is a chimeric anti-CD20 monoclonal antibody that depletes B cells and is effective in numerous autoimmune diseases including antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. We aim to evaluate the safety and efficacy of RTX in inducing remission of renal disease activity in patients with CSS. METHODS We conducted a single-center, open-label pilot study using RTX (375 mg/m(2)/week × 4) for induction of remission in CSS patients with renal involvement [defined as having >25% dysmorphic red cells, red blood cell casts or pauci-immune GN on biopsy]. Written informed consent was obtained from all individuals. Patients were eligible if they were untreated, had failed glucocorticoid therapy or had failed glucocorticoid dose reductions because of disease relapses. The primary outcome was remission of renal disease activity defined as stability or improvement of creatinine clearance, absence of active urinary sediment and reduction of the glucocorticoid dose to <50% of the average dose received over 3 months before enrollment or <10 mg/day (whichever is smaller) at 6 months. Patients were followed up for 1 year. RESULTS Only three patients (two females; ages 54, 55 and 65) were enrolled. All patients had positive myeloperoxidase-ANCA and renal involvement. Two patients had biopsy-proven pauci-immune crescentic GN. All achieved the primary end point of renal remission within the first 3 months and remained in renal remission during the year following RTX treatment. One patient experienced a nonrenal relapse (eye and joint involvement) at 6 months coinciding with the reconstitution of CD19+ cells and eosinophilia. He was retreated with RTX and achieved remission within 6 weeks. No major adverse effects were recorded. CONCLUSIONS In this pilot study, RTX was safe and successful in controlling renal disease activity in three patients with CSS. This agent deserves further study in CSS.

Abstract
Churg-Strauss syndrome is a rare small-vessel vasculitis that is associated with asthma, granulomatous inflammation, peripheral/tissue eosinophilia and a positive antineutrophil cytoplasmic antibody status (in approximately 40% of patients). The disease can be organ- and life-threatening, either due to tissue eosinophil infiltration such as myocarditis or due to vasculitis manifestations, for example glomerulonephritis. Furthermore, life-threatening disease can also occur due to the side effects of immunosuppression, for example, infection. A thorough diagnostic work-up should be performed in order to identify all organs involved and to rule out other disorders with similar features, such as hypereosinophilic syndrome. Therapeutic management is conducted according to disease stage and activity. Glucocorticoids remain the mainstay of therapy; however, further immunosuppressants (e.g., cyclophosphamide for life-threatening disease) are usually required. Future promising therapy options target cytokines involved in the disease process, such as IL-5.
