Abstract
INTRODUCTION We summarize evidence for the role of therapeutic plasma exchange (TPE) in the treatment of anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). TPE rapidly removes ANCA IgG, complement and coagulation factors important in the pathogenesis of AAV. TPE has been used in patients with rapidly deteriorating renal function to achieve early disease control, allowing time for immunosuppressive agents to prevent resynthesis of ANCA. The PEXIVAS trial challenged the utility of TPE in AAV, as it did not show benefit of adjunctive TPE on a combined end point of end stage kidney disease (ESKD) and death. AREAS COVERED We analyze data from PEXIVAS and other trials of TPE in AAV, an up-to-date meta-analysis, and recently published large cohort studies. EXPERT OPINION There remains a role for the use of TPE in AAV in certain groups of patients, in particular those with severe renal involvement (Cr >500 μmol/L or dialysis-dependent). It should be considered in patients with Cr >300 μmol/L and rapidly deteriorating function, or with life-threatening pulmonary hemorrhage. A separate indication is patients double positive for anti-GBM antibodies and ANCA. TPE may have the greatest benefit as part of steroid-sparing immunosuppressive treatment strategies.

Abstract
Introduction In the 330-patient ADVOCATE trial of avacopan for the treatment of antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, in which 81% of patients had renal involvement, estimated glomerular filtration rate (eGFR) increased on average 7.3 ml/min per 1.73 m2 in the avacopan group and 4.1 ml/min per 1.73 m2 in the prednisone group (P = 0.029) at week 52. This new analysis examines the results in the patient subgroup with severe renal insufficiency at enrollment into the trial, i.e., eGFR ≤20 ml/min per 1.73 m2. Methods eGFR was determined at baseline and over the course of the trial. Changes in eGFR were compared between the 2 treatment groups. Results In ADVOCATE, 27 of 166 patients (16%) in the avacopan group and 23 of 164 patients (14%) in the prednisone group had a baseline eGFR ≤20 ml/min per 1.73 m2. At week 52, eGFR increased on average 16.1 and 7.7 ml/min per 1.73 m2 in the avacopan and prednisone groups, respectively (P = 0.003). The last eGFR value measured during the 52-week treatment period was ≥2-fold higher than baseline in 41% of patients in the avacopan group compared to 13% in the prednisone group (P = 0.030). More patients in the avacopan group versus prednisone group had increases in eGFR above 20, 30, and 45 ml/min per 1.73 m2, respectively. Serious adverse events occurred in 13 of 27 patients (48%) in the avacopan group and 16 of 23 patients (70%) in the prednisone group. Conclusion Among patients with baseline eGFR ≤20 ml/min per 1.73 m2 in the ADVOCATE trial, eGFR improved more in the avacopan group than in the prednisone group.

Abstract
CLINICAL QUESTIONS What is the role of plasma exchange and what is the optimal dose of glucocorticoids in the first 6 months of therapy of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV)? This guideline was triggered by the publication of a new randomised controlled trial. CURRENT PRACTICE Existing guideline recommendations vary regarding the use of plasma exchange in AAV and lack explicit recommendations regarding the tapering regimen of glucocorticoids during induction therapy. RECOMMENDATIONS The guideline panel makes a weak recommendation against plasma exchange in patients with low or low-moderate risk of developing end stage kidney disease (ESKD), and a weak recommendation in favour of plasma exchange in patients with moderate-high or high risk of developing ESKD. For patients with pulmonary haemorrhage without renal involvement, the panel suggests not using plasma exchange (weak recommendation). The panel made a strong recommendation in favour of a reduced dose rather than standard dose regimen of glucocorticoids, which involves a more rapid taper rate and lower cumulative dose during the first six months of therapy. HOW THIS GUIDELINE WAS CREATED A guideline panel including patients, a care giver, clinicians, content experts, and methodologists produced these recommendations using GRADE and in adherence with standards for trustworthy guidelines. The recommendations are based on two linked systematic reviews. The panel took an individual patient perspective in the development of recommendations. THE EVIDENCE The systematic review of plasma exchange identified nine randomised controlled trials (RCTs) that enrolled 1060 patients with AAV. Plasma exchange probably has little or no effect on mortality or disease relapse (moderate and low certainty). Plasma exchange probably reduces the one year risk of ESKD (approximately 0.1% reduction in those with low risk, 2.1% reduction in those with low-moderate risk, 4.6% reduction in those with moderate-high risk, and 16.0% reduction in those with high risk or requiring dialysis) but increases the risk of serious infections (approximately 2.7% increase in those with low risk, 4.9% increase in those with low-moderate risk, 8.5% increase in those with moderate-high risk, to 13.5% in high risk group) at 1 year (moderate to high certainty). The guideline panel agreed that most patients with low or low-moderate risk of developing ESKD would consider the harms to outweigh the benefits, while most of those with moderate-high or high risk would consider the benefits to outweigh the harms. For patients with pulmonary haemorrhage without kidney involvement, based on indirect evidence, plasma exchange may have little or no effect on death (very low certainty) but may have an important increase in serious infections at 1 year (approximately 6.8% increase, low certainty). The systematic review of different dose regimens of glucocorticoids identified two RCTs at low risk of bias with 704 and 140 patients respectively. A reduced dose regimen of glucocorticoid probably reduces the risk of serious infections by approximately 5.9% to 12.8% and probably does not increase the risk of ESKD at the follow-up of 6 months to longer than 1 year (moderate certainty for both outcomes). UNDERSTANDING THE RECOMMENDATION The recommendations were made with the understanding that patients would place a high value on reduction in ESKD and less value on avoiding serious infections. The panel concluded that most (50-90%) of fully informed patients with AAV and with low or low-moderate risk of developing ESKD with or without pulmonary haemorrhage would decline plasma exchange, whereas most patients with moderate-high or high risk or requiring dialysis with or without pulmonary haemorrhage would choose to receive plasma exchange. The panel also inferred that the majority of fully informed patients with pulmonary haemorrhage without kidney involvement would decline plasma exchange and that all or almost all (≥90%) fully informed patients with AAV would choose a reduced dose regimen of glucocorticoids during the first 6 months of therapy.

Abstract
Due to complex comorbidity, high infectious complication rates, an elevated risk of relapsing for primary renal disease, as well as inferior recipient and allograft survivals, individuals with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs) are often considered as poor transplant candidates. Although several aspects of recurrent and de novo AAVs remain unclear, recent evidence suggests that kidney transplantation (KT) represents the best option, which is also the case for this particular subgroup of patients. Special counselling and individualized approaches are strongly recommended at the time of enlistment and during the entire post-transplant follow-up. Current strategies include avoiding transplantation within one year of complete clinical remission and thoroughly assessing the recipient for early signs of renal or systemic vasculitis. The main clinical manifestations of allograft AAV are impaired kidney function, proteinuria, and hematuria with ANCA positivity in most cases. Mixed results have been obtained using high-dose steroids, mycophenolate mofetil, or cyclophosphamide. The aim of the present review was to summarize the available literature on AAVs in KT, particularly focusing on de novo pauci-immune glomerulonephritis.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis can present with life-threatening lung-kidney syndromes. However, many controlled treatment trials excluded patients with diffuse alveolar hemorrhage or severely impaired glomerular filtration rates, and so the optimum treatment in these cases is unclear. In this retrospective cohort study, we report the outcomes of 64 patients with life-threatening disease treated with a combination regimen of rituximab, low-dose intravenous cyclophosphamide, oral glucocorticoids, and plasma exchange. At entry, the median estimated glomerular filtration rate was 9 mL/min, 47% of patients required dialysis, and 52% had diffuse alveolar hemorrhage. All patients received a minimum of seven plasma exchanges, and the median cumulative doses of rituximab, cyclophosphamide, and glucocorticoid were 2, 3, and 2.6 g, respectively, at six months. A total of 94% of patients had achieved disease remission (version 3 Birmingham Vasculitis Activity Score of 0) at this time point, and 67% of patients who required dialysis recovered independent kidney function. During long-term follow-up (median duration 46 months), overall patient survival was 85%, and 69% of patients remained free from end-stage kidney disease, which compares favorably to a historic cohort with severe disease treated with a conventional induction regimen. Combination treatment was associated with prolonged B cell depletion and low rates of relapse; 87% of patients were in continuous remission at month 36. The serious infection rate during total follow-up was 0.28 infections/patient/year, suggesting that combination treatment is not associated with an enduring risk of infection. Thus, we suggest that combination immunosuppressive therapy may permit glucocorticoid avoidance and provide rapid and prolonged disease control in patients with severe ANCA-associated vasculitis.

Abstract
Introduction Crescentic glomerulonephritis (CrGN) is a histologic feature of severe glomerular injury, clinically characterized by a rapid decline of renal function when not treated in a timely fashion. Factors associated with CrGN prognosis have not been thoroughly investigated. This study investigated the prognostic predictors of renal outcomes associated with CrGN, such as the histopathologic classification of anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis, arteriosclerosis, and tertiary lymphoid organ (TLO) formation. Methods A total of 114 patients diagnosed with CrGN between 2010 and 2018 at two university-based hospitals has been retrospectively analyzed. Relationships between potential predictors and renal outcomes were analyzed using Cox proportional hazards model and linear regression analysis. Results The mean age was 61.0 ± 15.3 years, and 49.1% were male. Among them, 92 (80.7%) and 11 (9.6%) patients were positive for ANCA and for anti-glomerular basement membrane antibody, respectively. During the median follow-up of 458.0 days, 55 patients (48.2%) had advanced to end-stage renal disease (ESRD). Cox proportional hazards analysis revealed that patients under the mixed and sclerotic classes had worse renal survival compared to those in the focal class (mixed: hazard ratio [HR], 3.74; 95% confidence interval [CI], 1.18 to 11.82; P = 0.025; sclerotic: HR, 4.84; 95% CI, 1.44 to 16.32; P = 0.011). Severe arteriosclerosis was also associated with poor renal survival (HR, 2.44; 95% CI, 1.04 to 5.77; P = 0.042). TLOs were observed in 41 patients (36.0%). Moreover, TLO formation was also a prognostic factor for ESRD (HR, 1.82; 95% CI, 1.03 to 3.21; P = 0.040). In the multivariate linear regression analysis, age and sclerotic class were independent predictors for the change in estimated glomerular filtration rate during 1 year after biopsy. Conclusions Specific histopathologic findings, histopathologic classification, severity of arteriosclerosis, and TLO formation provide helpful information in predicting renal outcomes associated with CrGN.

Abstract
Therapeutic plasma exchanges (TPE) is considered as one of the treatment modalities that is used in systemic autoimmune diseases. This study aimed to describe the early and late effect of TPE in patients with systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) presented with acute kidney injury (AKI). Retrospective study comprised patients with SLE and AAV with AKI seen between January 2000 and June 2014 at King Faisal Specialist Hospital and Research Center in Riyadh. All patients underwent TPE. Retrospectively, all patients were assessed for early and late renal outcome at 12- month and 24-month intervals. Renal outcome was assessed according to serum creatinine level, glomerular filtration rate, active urine sediment, and proteinuria. P <0.05 was considered significant. A total of 68 patients were included, 58 patients (51 females) had SLE and 10 patients (7 females) had AAV completed TPE. All patients had active disease and had AKI. At the first 12 months, 18 patients (17 SLE and 1 AAV) showed complete response and 14 patients had partial response while 22 patients did not show therapeutic benefit. The nonresponders (22 patients) entered the late assessment interval (24 months) without any therapeutic response. Statistically, there was no significant difference between the patient's response to TPE at the first and second assessment intervals and the baseline serum creatinine level. TPE might be an alternative rescue treatment in lupus nephritis with AKI.

Abstract
Plasma exchange (PEX) can be an effective treatment in anti-neutrophil cytoplasmic antibody-associated vasculitis with severe renal damage; however, it is still controversial. Among cases of newly diagnosed AAV with rapidly progressive glomerulonephritis at our department from 2008 onward, 11 patients who received PEX (seven cases for severe renal damage [R-PEX] and four cases for lung hemorrhage [L-PEX]) were retrospectively analyzed. All cases of R-PEX were dependent on hemodialysis at the beginning of PEX and all received seven sessions of PEX (50 mL/kg or 1.3 plasma volume per exchange) within 2 weeks. All cases became dialysis-independent within 8 weeks, with 3- and 12-month cumulative renal survival rates of 100% and 80%, respectively. All cases of L-PEX retained their renal function. In rapidly developing, newly dialysis-dependent antibody-associated vasculitis with rapidly progressive glomerulonephritis patients with normal renal function before disease onset, standard PEX can be expected to induce sufficient renal recovery to establish dialysis independence.

Abstract
Introduction Autoimmune diseases include a diverse and complex group of pathologies with a broad clinical spectrum due to the production of autoantibodies, which generates multisystemic compromise. Therapeutic plasma exchange (TPE) is a good additive treatment for immunosuppression due to its action over the autoantibodies. Objectives To describe the main clinical characteristics and outcomes of patients with systemic lupus erythematosus and other systemic autoimmune diseases managed with TPE. Methodology This descriptive retrospective study enrolled patients with systemic autoimmune diseases who received TPE. Results In total, 66 patients with a median age of 33.5 years (24-53 years) were included; the majority were females [n=51 (77.27%)]. Forty (60.61%) patients were diagnosed with systemic lupus erythematosus. In these cases, the main indication for TPE was diffuse alveolar hemorrhage (DAH; n=20, 30.3%) and neurolupus (n=9, 13.6%). No TPE-related deaths occurred, and the main complication was hemorrhage, without significant differences among the four types of TPE solutions used. The overall outcome was improvement in 41 (62.12%) patients. Conclusion TPE is safe and effective in patients with severe manifestations of autoimmune diseases.

Abstract
Rituximab (RTX) has become a therapeutic option for inducing remission of anti-neutrophil cytoplasmic autoantibody-associated vasculitis (AAV). However, the optimum dosage of RTX to induce remission of AAV and reduce adverse events, such as infection, remains unclear. We herein report an elderly and renally impaired patient with alveolar hemorrhaging due to refractory AAV who was successfully treated with single infusion of RTX. Single infusion of RTX may be a therapeutic option in refractory AAV patients who are vulnerable to infections.

Abstract
The prognosis of ANCA-associated vasculitis has been transformed in recent years. Once it was a set of invariably acute and fatal conditions, but these disorders are currently considered to be chronic diseases. This change is largely attributable to earlier diagnosis and the careful application of immunotherapeutics. However, patients still experience premature mortality, relapse, comorbid ill health and poor quality of life. Mortality rates in large-vessel vasculitis are not comparable; however, morbidity and poor patient outcomes prevail. Toxicity secondary to glucocorticoids represents a common driver of poor outcomes across systemic vasculitis. The main thrust of future treatment strategies is to reduce if not eliminate exposure to these agents.

Abstract
Background: Recently proposed histopathological classification may predict patient outcome in pauci-immune glomerulonephritis. This study sought to prove that the prognostic effect could be extended to all types of rapidly progressive glomerulonephritis. Methods: Retrospective analysis of patients diagnosed with rapidly progressive glomerulonephritis between April 1999 and August 2015 was performed. Epidemiological and clinical data were collected from medical records. The descriptions of renal biopsies were reviewed and classified into focal, sclerotic, crescentic and mixed class according to classification proposed by Berden et al. The study end points were end stage renal disease (ESRD) or death. Survival analyses were modelled using Cox regression. Results: 73 renal biopsies with diagnosis of rapidly progressive glomerulonephritis were included in the study. 25 (34.2%), 16 (21.9%), 24 (32.9%) and 8 (11%) patients were assigned to focal, crescentic, mixed and sclerotic class, respectively. Thirty-two (42.5%) patients were anti-neutrophil cytoplasmic antibody (ANCA) negative, of which eight (10.9%) were anti–glomerular basement membrane antibody (anti–GBM) positive and 24 (32.8%) were negative for autoimmune antibodies. Six (8.2%) patients died within one year. Among patients who survived, median change in estimated glomerular filtration rate (eGFR) values were: −10.5 mL/min in focal, 4.2 mL/min in crescentic, −4.3 mL/min in mixed and 4.1 mL/min in sclerotic group, p > 0.05. In the Cox regression model, there was no significant predictor of patient survival whereas the sclerotic group (HR 3.679, 95% CI, 1.164–11.628, p < 0.05) and baseline eGFR of <15 mL/min (HR 4.832, 95% CI, 1.55–15.08, p < 0.01) had an unfavorable effect for renal survival. Conclusions: Predominant glomerular sclerosis and low eGFR at baseline are associated with higher risk of ESRD in cases with crescentic glomerulonephritis. Therefore, despite the origin of injury, histological classification might aid in prediction of patient outcomes in rapidly progressive glomerulonephritis.

Abstract
Therapeutic plasma aphresis (plasmapheresis) is one form of treatment that is frequently used in practice of Nephrology. Plasmapheresis is the most important part of the therapies for Goodpasture's syndrome and anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis which are causes of rapidly progressive glomerulonephritis. The reason why the effectiveness of plasmapheresis therapy cannot be clearly demonstrated in renal involvement in these diseases is that it does not appear to be possible to recruit an adequate number of patients and plasmapheresis is not effective in advanced disease if early treatment is not initiated.

Abstract
<b><i>Background:</i></b> Rapidly progressive glomerulonephritis (RPGN) is characterized by a rapid deterioration of renal function and by extracapillary proliferation in >50% of glomeruli. The most common type of RPGN is “pauci-immune” glomerulonephritis caused by anti-neutrophil cytoplasmic antibodies-associated vasculitis (AAV). <b><i>Summary:</i></b> The incidence of AAV increases with age<b><i></i></b> and pauci-immune glomerulonephritis is the most common diagnosis found in renal biopsies in the elderly population. Age was identified as an independent negative risk factor for both death and end-stage renal disease in AAV, and the mortality of older patients was uniformly higher than in younger patients in all retrospective studies. Early diagnosis may be difficult particularly in elderly patients with renal-limited disease but is important for the good outcome of the patients. Immunosuppressive treatment options include cyclophosphamide or rituximab combined with corticosteroids with or without plasma exchange in case of severe disease. Data from randomized trials are completely missing for patient aged >75 years. Based on retrospective studies, elderly patients seem to respond to immunosuppressive drugs just as younger patients are able to, but they are at a higher risk of adverse events.<b><i> Key Messages:</i></b> RPGN is relatively common in the elderly patients. Immunosuppressive treatment in older patients with AAV or RPGN may be useful but needs to be strictly individualized with all the risks taken into consideration. Further studies are needed to examine the role of novel therapeutic options in the elderly population with RPGN.

Abstract
This paper reviews the recently published scientific information regarding ANCA-associated vasculitis (AAV), aiming to highlight the most important data from the clinical nephrologists' perspective. The classification, pathomechanism, recent achievements of the treatment, short-term and long-term outcomes of the disease, and the difficulties nephrologists face when taking care for patients with AAV are summarized. There has been significant progress in the understanding of the genetic and pathologic background of the disease in the last years, and results of histological studies guide us to predict long-term renal function. Findings of several multicentered trials with reasonable number of participants provide comparison of the efficacy and safety of different remission induction and maintenance therapies, and evaluate recently introduced immunosuppressive agents. Although the clinical outcome of patients with AAV has improved significantly since modern immunosuppressive drugs are available, the treatment-related complications still contribute to the morbidity and mortality. To improve the survival and quality of life of patients with AAV further, knowledge of the predictors of relapse, end-stage kidney disease, and mortality, also prevention of infections and other treatment-related adverse events are important. The eligibility for renal transplantation and the option for successful pregnancies for young women are also important factors which influence the patients' quality of life. In order to provide favorable outcome, the clinicians need to establish personalized treatment strategies to optimize the intensity and minimize the toxicity of the immunosuppressive therapy.

Abstract
BACKGROUND/AIMS Anti-neutrophil cytoplasmic autoantibody-associated vasculitis (AAV) is a cause of biopsy-proven acute kidney injury, more common in the elderly. Treatment requires immunosuppression, which can have significant toxic effects. The aim of this study was to assess whether morbidity and mortality that are associated with immunosuppression for AAV varied with age. METHODS A retrospective review of 232 patients given induction therapy with prednisolone and cyclophosphamide was conducted. Information was collected on baseline characteristics (including requirement for dialysis at presentation) and the occurrence of leukopenia, infection, end-stage renal disease and death during follow-up. RESULTS Median follow-up was 51 months. Older patients (aged ≥70 years) were treated with lower total cyclophosphamide doses than those aged <70 years (mean 7.3 g (SD 4.4) vs. 10.7 g (SD 7.4), respectively). Increasing age was associated with an increased risk of leukopenia (odds ratio (OR) 1.50; 95% confidence interval (CI) 1.20-1.86; p < 0.001), and older patients were more likely to develop infections in the first year (OR 1.87; 95% CI 1.1-3.2). Older patients were also significantly more likely to require dialysis at presentation (OR 1.66; 95% CI 1.13-2.5) and longer term. After multivariable adjustment, age and requirement for dialysis at presentation were significant predictors of death (hazard ratio (HR) per year of age 1.07; 95% CI 1.03-1.11; p < 0.001 and HR 2.2; 95% CI 1.10-4.38; p = 0.03, respectively). CONCLUSIONS Among patients treated with prednisolone and cyclophosphamide, increasing age and dialysis dependency were associated with worse survival. Older patients were more likely to develop treatment-related complications despite lower cumulative doses of immunosuppression. Morbidity and mortality associated with treatment must therefore be carefully balanced against that associated with the disease process itself.

Abstract
BACKGROUND Plasma exchange (PLEX) has been used routinely for treatment of severe renal vasculitis and/or alveolar haemorrhage (AH) in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but the long-term benefit of PLEX in AAV remains unclear. We aimed to describe the characteristics and outcomes of patients treated with PLEX in a single centre. METHODS Patients with AAV were identified by performing a case review of medical records of 705 patients who received PLEX in a single tertiary referral centre between 2000 and 2010. Patient characteristics and outcomes were recorded. The Kaplan-Meier method, log-rank tests and Cox regression analysis were used for survival analyses. RESULTS A total of 94 patients with AAV were identified (44 men, 50 women; median age 60 years, range 21-90 years; 52 proteinase 3-ANCA, 41 myeloperoxidase-ANCA and 1 ANCA-negative; 8 double-positive for ANCA and anti-glomerular basement membrane; 93 newly diagnosed/1 relapse; 55 [58.5 %] required dialysis). The reasons for initiating PLEX therapy were severe renal involvement alone in 52 %, AH in 10 %, both renal involvement and AH in 35 %, and "other" in 3 %. The patients had 3-27 (median 7) PLEX sessions. At 3 months, 81 (86 %) of 94 were alive and 62 (66 %) of 94 were alive and dialysis-independent. The median follow-up was 41 months (minimum-maximum 0.5-137 months), when 56 (59.6 %) of 94 patients were alive and 47 (50 %) were dialysis-independent. The estimated overall survival rates were 75.3 % at 1 year and 61.1 % at 5 years. Patient survival decreased with increasing age at presentation (5-year survival 85 % for age <50 years, 64.4 % for ages 50-65 years, and 41 % for >65 years; p < 0.01 for comparison between all groups). Estimated renal survival rates were 65.5 % at 1 year and 43 % at 5 years. Renal survival was worse in patients aged >65 years than in the younger patients (5-year survival 25.1 % in patients >65 years vs. 50.8 % for those ≤65 years, p < 0.01). The estimated renal survival was better in patients with higher Disease Extent Index (DEI) >6 than in patients with DEI ≤6 (5-year survival 52.1 % vs. 39.4 %, p = 0.04), even though this was not confirmed in multivariate analysis. CONCLUSIONS The mortality of patients presenting with severe manifestations of AAV remains high despite the use of PLEX. Older age at presentation is associated with worse overall and renal prognosis.

Abstract
BACKGROUND Diffuse alveolar hemorrhage (DAH) is an uncommon but potentially life-threatening manifestation of systemic lupus erythematosus (SLE) associated with high mortality. Although survival and its associated clinical, laboratory, and therapeutic features have been reported for case reports and series, they have not been systematically reviewed. OBJECTIVES The purpose of this systematic review was to assess survival of episodes of DAH in SLE over 3 decades and to categorize trends in therapies, commonly utilized to treat this disorder. RESULTS Overall, SLE patients survived 61% of 174 DAH episodes representing 140 patients. Episode survival was 67% in the time period from 2000 to 2013. Corticosteroids were nearly universally used therapeutically, and cyclophosphamide was used in 55%. Plasmapheresis was used in 31% and did not appear to be associated with survival. CONCLUSIONS Diffuse alveolar hemorrhage in SLE still carries a high risk of mortality; however, survival trends appear to demonstrate an increase from approximately 25% in the 1980s to 67% in the current decade. Increased use of cyclophosphamide appears to be associated with better survival, whereas plasmapheresis does not appear to influence outcome. Although these results need to be interpreted with caution because they are not derived from randomized controlled trials, we believe this represents the largest reported compilation of survival data in DAH associated with SLE.

Abstract
Antiglomerular basement membrane (anti-GBM) antibodies are more often accompanied by myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) than by proteinase 3 antineutrophil cytoplasmic antibody (PR3-ANCA). Both disease processes can affect the kidneys and/or the lungs. Patients with dual positive disease may have an atypical presentation which may delay diagnosis and treatment. Here we report a case of crescentic glomerulonephritis associated with positive PR3-ANCA and anti-GBM antibodies who underwent both lung and kidney biopsies.

Abstract
Our aim was to investigate the clinical efficacy of double filtration plasmapheresis (DFPP) in the treatment of antineutrophil cytoplasmic autoantibody-(ANCA) associated vasculitis (AAV) with severe renal involvement. Fifteen AAV patients who had severe renal failure (median SCr 5.6(IQR 5.2-9.0) mg/dL) and needed initial renal replacement therapy (RRT) were treated with DFPP and immunosuppressive therapy. Two plasma volumes were processed during each DFPP session. The changes of serum ANCA and renal function were investigated. After the DFPP treatment for three to five sessions, serum MPO-ANCA level decreased from 250.0 ± 86.9 RU/mL to 70.5 ± 64.7RU/mL (P = 0.00), with a median reduction rate of 67.6%. Eleven patients (73.3%) no longer needed from RRT 3 months after DFPP treatment, while another four patients remained on dialysis. During the follow up for median 10 (IQR 6-24) months, SCr level decreased to normal in one patient, one patient progressed into ESRD. The 1 year renal survival rate was 62.9%. Five (33.3%) patients were complicated with pulmonary infection. DFPP combined with immunosuppressive therapy could increase the renal recovery rate through rapidly decreasing serum ANCA levels for AAV patients with severe renal failure, but its clinical efficacy and impact on long-term renal survival require further studies.

Abstract
Background Current recommendations for ANCA-associated vasculitis (AAV) support its management within a dedicated clinical service. Therapies for AAV are imperfect with many patients failing to achieve disease control and others experiencing disease relapse. Plasma exchange (PEX) may be beneficial especially when the kidney is involved. Methods Within a new, dedicated service we retrospectively assessed, over a 6-year period, the benefits of PEX in two patient cohorts, discriminated by PEX treatment alone. Patients received PEX alongside standard of care if they fulfilled any of the following criteria: 1. serum creatinine >500 μmol/l or dialysis-requiring renal failure, 2. alveolar haemorrhage, 3. renal biopsy showing ≥30 % focal and necrotising lesions ± cellular crescents. Outcome measures included disease remission and relapse, cumulative immunosuppression, and morbidity and mortality. Results Of 104 new patients, 58 patients received PEX at presentation, 46 did not. Cyclophosphamide and/or rituximab dosing was similar for both groups. Although patients receiving PEX had poorer renal function, a higher C-reactive protein and disease activity score at presentation disease remission rate was similar in both groups (no PEX vs. PEX: 96 % vs. 98 %). The PEX group entered remission quicker (no PEX vs. PEX: 3.9 ± 4.0 vs. 2.8 ± 1.3 months, p < 0.05), with a lower 3-month cumulative glucocorticoid dose (no PEX vs. PEX: 2.5 ± 0.4 vs. 2.3 ± 0.2 g, p < 0.001). Relapse was similar between groups but adverse events lower in the PEX group. Conclusions PEX may be of benefit in AAV. Larger, longer randomised controlled trials are now needed.

Abstract
A 69-year-old male had initially presented with low-grade proteinuria, microhematuria, and a positive myeloperoxidase anti-neutrophilic antibody (ANCA). He subsequently developed deterioration of kidney function and developed uremic symptoms. Creatinine was 486.2 μmol/L (5.5 mg/dL). Anti-MPO was positive (titer >8 U, normal <0.4). He was clinically diagnosed with rapidly proliferative glomerulonephritis most likely due to ANCA vasculitis. He received three doses of pulse methylprednisolone therapy. Kidney biopsy showed pauci-immune glomerulonephritis. Immunofluorescence was positive for faint linear IgG staining of glomerular basement membrane (GBM). Anti-GBM antibody was positive 2.1 U (normal <1). He was started on high-dose oral steroids; monthly intravenous cyclophosphamide and plasmapheresis were also initiated. His symptoms improved and creatinine is 247.5 μmol/L (2.8 mg/dL). His repeat anti-GBM antibody was negative. This is a rare case of rapidly progressive glomerulonephritis due to dual MPO-ANCA antibodies and anti-GBM antibodies (DAV).

Abstract
INTRODUCTION Antineutrophil cytoplasmic antibodies-associated vasculitis (AAV) is a group of autoimmune diseases characterized by the necrotizing inflammation of small vessels and associated with the antineutrophil cytoplasmic antibodies. Treatment of AAV can be divided into the induction phase aimed at achieving remission of the disease and the maintenance phase aimed at prevention of relapses. Long-term outcome of AAV dramatically improved with the introduction of cyclophosphamide. Recent clinical studies resulted in the reduction of the cumulative dose of cyclophosphamide and introduction of new treatment options, namely B-cell-depleting antibody rituximab, into both induction and maintenance treatment. This paper aims to evaluate the current role of the conventional induction and maintenance treatment in view of the gradually increasing use of rituximab. AREAS COVERED This paper provides an overview of the main clinical studies in induction and maintenance treatment of adult patients with AAV, treatment of relapses of AAV and shortly comments also on the treatment of refractory AAV, treatment of different subgroups of AAV (based on the age, renal function, clinical presentation and type of autoantibody), long-term outcome of patients with AAV, adverse events of treatment and treatment of end-stage renal disease in AAV. EXPERT OPINION Our analysis demonstrates that although the introduction of rituximab modified the approach to both the induction and maintenance treatment of AAV, more conventional induction and maintenance treatment with standard immunosuppressive drugs still retains its importance as we need more data on long-term efficacy and safety of biologic treatment, and also its cost-effectiveness still remains an open issue.

Abstract
BACKGROUND Pauci-immune glomerulonephritis (GN) represents a severe form of glomerular injury and is the most common cause of crescentic GN in adults. To date, the clinicopathologic features of pauci-immune GN are not well characterized in the pediatric population. METHODS Twenty-six biopsies from 21 pediatric patients with pauci-immune GN were identified retrospectively from the pathology archives of the University of Chicago (biopsy incidence 5 % among pediatric patients). RESULTS There was distinct female predominance (2.5:1) among the patient cohort. Serologic studies identified anti-neutrophil cytoplasmic antibodies (ANCA) in 85 % of patients, and 80 % had systemic manifestations of vasculitis. The median estimated glomerular filtration rate (eGFR) at presentation was 43 ml/min/1.73 m(2). Based on a previously proposed classification of ANCA-associated GN, we identified a spectrum of injury, including crescentic (n = 9), focal (n = 7), mixed (n = 5) and sclerotic GN (n = 5). Necrotizing arteritis was identified in a minority of patients (n = 3). The majority of those patients for whom data were available had been treated with cyclophosphamide and corticosteroids, with or without rituximab. Of the 21 pediatric patients, 58 % had developed chronic kidney disease at follow-up (eGFR <90 ml/min/1.73 m(2)), of whom 85 % of those had crescentic, mixed or sclerotic GN. CONCLUSION Pediatric patients with pauci-immune GN are similar to their adult counterparts in terms of clinical manifestations and histopathologic findings. Among the 21 patients in our study, those with focal GN had the best outcomes while patients with crescentic, mixed or sclerotic GN overwhelmingly had a poor long-term outcome for kidney function.

Abstract
BACKGROUND Rituximab (RTX) is approved for remission induction in ANCA associated vasculitis (AAV). However, data on use of RTX in patients with severe renal disease is lacking. METHODS We conducted a retrospective multi-center study to evaluate the efficacy and safety of RTX with glucocorticoids (GC) with and without use of concomitant cyclophosphamide (CYC) for remission induction in patients presenting with e GFR less than 20 ml/min/1.73 m(2). We evaluated outcomes of remission at 6 months (6 M), renal recovery after acute dialysis at diagnosis, e-GFR rise at 6 M, patient and renal survival and adverse events. RESULTS A total 37 patients met the inclusion criteria. The median age was 61 years. (55-73), 62 % were males, 78 % had new diagnosis and 59 % were MPO ANCA positive. The median (IQR) e-GFR at diagnosis was 13 ml/min/1.73 m(2) (7-16) and 15 required acute dialysis. Eleven (30 %) had alveolar hemorrhage. Twelve (32 %) received RTX with GC, 25 (68 %) received RTX with GC and CYC and seventeen (46 %) received plasma exchange. The median (IQR) follow up was 973 (200-1656) days. Thirty two of 33 patients (97 %) achieved remission at 6 M and 10 of 15 patients (67 %) requiring dialysis recovered renal function. The median prednisone dose at 6 M was 6 mg/day. The mean (SD) increase in e-GFR at 6 months was 14.5 (22) ml/min/m(2). Twelve patients developed ESRD during follow up. There were 3 deaths in the first 6 months. When stratified by use of concomitant CYC, there were no differences in baseline e GFR, use of plasmapheresis, RTX dosing regimen or median follow up days between the groups. No differences in remission, renal recovery ESRD or death were observed. CONCLUSIONS This study of AAV patients with severe renal disease demonstrates that the outcomes appear equivalent when treated with RTX and GC with or without concomitant CYC.

Abstract
Demonstration of a pathogenic role for antineutrophil cytoplasmic antibodies (ANCA) underlies the scientific rationale for plasma exchange (PLEX) in the treatment of ANCA-associated vasculitis (AAV). Most clinical evidence of efficacy concerns the use of PLEX for the recovery of renal function in severe nephritis, when used in conjunction with immunosuppressive drug therapy. The development of PLEX for this indication, the strength of the clinical trial evidence supporting its use, its roles in other AAV indications and ongoing research are discussed.

Abstract
Antineutrophil cytoplasmic autoantibody (ANCA)-associated diseases are small-vessel vasculitides, encompassing granulomatosis with polyangiitis (formerly Wegener's granulomatosis), microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. Once considered life-threatening diseases, the introduction of stage-adapted immunosuppressive therapy and medications with decreased toxicity has improved patients' survival. Treatment is biphasic, consisting of induction of remission (3-6 months) for rapid control of disease activity and maintenance of remission (at least 18 months) to prevent disease relapse using therapeutic alternatives that have reduced toxicity. This Review summarizes current treatment strategies for these diseases, with a special focus on long-term follow-up data from key randomized controlled trials and new developments in remission induction and maintenance therapy. Current treatment strategies have substantial short-term and long-term adverse effects, and relapses are frequent; thus, less-toxic and more-effective approaches are needed. Moreover, the optimal intensity and duration of maintenance therapy remains under debate. Clinical trials have traditionally considered ANCA-associated vasculitides as a single disease entity. However, future studies must stratify participants according to their specific disease, clinical features (different types of organ manifestation, PR3-ANCA or MPO-ANCA positivity) and disease severity.

Abstract
The value of classification systems applied to the examination of renal biopsies is based on several factors: first, on the ability to provide efficient communication between pathologists and between pathologists and clinicians; second, on the possibility to implement diagnostic information with prognostic indication. Even more important, the practical value of a classification is proved by the ability of providing elements that guide therapeutic decisions and can be used in the follow-up of the patient. With these aims, new histologic classification systems have been proposed in the last decade for lupus nephritis and IgA nephropathy under the leadership of the Renal Pathology Society and the International Society of Nephrology. These classifications have gained a significant level of worldwide acceptance and have been the subject of multiple single-center and multicenter validation studies, which have underpinned their clinical benefits and limitations and served to highlight remaining questions and difficulties of interpretation of the biopsy sample. More recently, a classification system has also been proposed for ANCA-associated crescentic glomerulonephritis (ANCA-GN), although the validation process for this is still in an early stage. In this review, we examine in some detail the ISN/RPS classification for lupus nephritis and the Oxford classification for IgA nephropathy, with emphasis on clinicopathologic correlations, their value for and evolving impact on clinical studies and clinical practice, and their significant limitations in this regard as exposed by validation studies. We also suggest possible ways by which these classifications might be modified to make them more applicable to clinical practice. Finally, we more briefly discuss the newly proposed classification for ANCA-GN.

Abstract
Objective Immunosuppression is cornerstone treatment of antineutrophil cytoplasmic antibody associated vasculitis (AAV) but is later complicated by infection, cancer, cardiovascular and chronic kidney disease. Caveolin-1 is an essential structural protein for small cell membrane invaginations known as caveolae. Its functional role has been associated with these complications. For the first time, caveolin-1 (CAV1) gene variation is studied in AAV. Methods CAV1 single nucleotide polymorphism rs4730751 was analysed in genomic DNA from 187 white patients with AAV from Birmingham, United Kingdom. The primary outcome measure was the composite endpoint of time to all-cause mortality or renal replacement therapy. Secondary endpoints included time to all-cause mortality, death from sepsis or vascular disease, cancer and renal replacement therapy. Validation of results was sought from 589 white AAV patients, from two European cohorts. Results The primary outcome occurred in 41.7% of Birmingham patients. In a multivariate model, non-CC genotype variation at the studied single nucleotide polymorphism was associated with increased risk from: the primary outcome measure [HR 1.86; 95% CI: 1.14-3.04; p=0.013], all-cause mortality [HR:1.83; 95% CI: 1.02-3.27; p=0.042], death from infection [HR:3.71; 95% CI: 1.28-10.77; p=0.016], death from vascular disease [HR:3.13; 95% CI: 1.07-9.10; p=0.037], and cancer [HR:5.55; 95% CI: 1.59-19.31; p=0.007]. In the validation cohort, the primary outcome rate was far lower (10.4%); no association between genotype and the studied endpoints was evident. Conclusions The presence of a CC genotype in Birmingham is associated with protection from adverse outcomes of immunosuppression treated AAV. Lack of replication in the European cohort may have resulted from low clinical event rates. These findings are worthy of further study in larger cohorts.
