Abstract
SIGNIFICANCE STATEMENT Reliable prediction tools are needed to personalize treatment in ANCA-associated GN. More than 1500 patients were collated in an international longitudinal study to revise the ANCA kidney risk score. The score showed satisfactory performance, mimicking the original study (Harrell's C=0.779). In the development cohort of 959 patients, no additional parameters aiding the tool were detected, but replacing the GFR with creatinine identified an additional cutoff. The parameter interstitial fibrosis and tubular atrophy was modified to allow wider access, risk points were reweighted, and a fourth risk group was created, improving predictive ability (C=0.831). In the validation, the new model performed similarly well with excellent calibration and discrimination ( n =480, C=0.821). The revised score optimizes prognostication for clinical practice and trials. BACKGROUND Reliable prediction tools are needed to personalize treatment in ANCA-associated GN. A retrospective international longitudinal cohort was collated to revise the ANCA renal risk score. METHODS The primary end point was ESKD with patients censored at last follow-up. Cox proportional hazards were used to reweight risk factors. Kaplan-Meier curves, Harrell's C statistic, receiver operating characteristics, and calibration plots were used to assess model performance. RESULTS Of 1591 patients, 1439 were included in the final analyses, 2:1 randomly allocated per center to development and validation cohorts (52% male, median age 64 years). In the development cohort ( n =959), the ANCA renal risk score was validated and calibrated, and parameters were reinvestigated modifying interstitial fibrosis and tubular atrophy allowing semiquantitative reporting. An additional cutoff for kidney function (K) was identified, and serum creatinine replaced GFR (K0: <250 µ mol/L=0, K1: 250-450 µ mol/L=4, K2: >450 µ mol/L=11 points). The risk points for the percentage of normal glomeruli (N) and interstitial fibrosis and tubular atrophy (T) were reweighted (N0: >25%=0, N1: 10%-25%=4, N2: <10%=7, T0: none/mild or <25%=0, T1: ≥ mild-moderate or ≥25%=3 points), and four risk groups created: low (0-4 points), moderate (5-11), high (12-18), and very high (21). Discrimination was C=0.831, and the 3-year kidney survival was 96%, 79%, 54%, and 19%, respectively. The revised score performed similarly well in the validation cohort with excellent calibration and discrimination ( n =480, C=0.821). CONCLUSIONS The updated score optimizes clinicopathologic prognostication for clinical practice and trials.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides are a group of diseases characterised by necrotizing inflammation of small vessels such as arterioles, venules, and capillaries. ANCA-associated vasculitides (AAV) are referred to as small vessel vasculitides. Three AAV subgroups, namely granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic GPA (EGPA), are defined according to clinical features. The most common disease with renal involvement in AAV is MPA Approximately 90% of patients with MPA have renal involvement. While this rate is 70-80% in GPA, less than half of EGPA patients have renal involvement. Untreated survival in AAVs is less than one year. With appropriate immunosuppressive therapy, the 5-year renal survival rate is 70-75%. Without therapy, the prognosis is poor but treatments, typically immunosuppressants, have improved survival, albeit with considerable morbidity from glucocorticoids and other immunosuppressive medications. Current challenges include improving the measures of disease activity and risk of relapse, uncertainty about optimal therapy duration and a need for targeted therapies with fewer adverse effects. In this review, we described the treatment of renal involvement in AAV in line with current studies.

Abstract
Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a necrotizing vasculitis characterized by small-to-medium-sized vessel involvement and the presence of antineutrophil cytoplasmic antibodies (ANCA). We present a case of a 26-year-old Asian woman who was transferred to our center from a nearby hospital, where she presented with shortness of breath, tested positive for COVID-19, and was being managed for COVID-19 pneumonia. She also had hemoptysis, skin lesions, and left foot numbness. Serological markers and VATS-guided lung biopsy confirmed the diagnosis. Treatment with methylprednisolone and rituximab led to stabilization, despite complications of subcutaneous emphysema and lower extremity neuropathic symptoms. Early recognition and appropriate management of GPA are crucial for optimal outcomes.

Abstract
Abstract
ANCA-associated vasculitides (AAV) are a group of rare, primary, systemic necrotizing small-vessel vasculitides. Granulomatosis with polyangiitis and microscopic polyangiitis account for ∼80–90% of all AAV. Exposure to silica dust, farming and chronic nasal Staphylococcus aureus carriage are associated with increased risk of developing AAV. When a diagnosis of AAV is suspected, as in patients with multisystem organ dysfunction or those with features such as chronic recurrent rhinosinusitis, cavitated lung nodules, palpable purpura or acute kidney injury, then appropriate further investigations are needed, including ANCA testing. In this scenario, a structured clinical assessment should be conducted, evaluating all the organs possibly involved, and tissue biopsy may be necessary for confirmation of the diagnosis. Therapeutic algorithms vary based on the severity of AAV, the clinical diagnosis/ANCA specificity, and the patient’s age, weight, comorbidities and prognosis. Recent data favour rituximab as a preferable option for both induction and maintenance of remission. In addition, regimens with less glucocorticoids are equally effective and safer in inducing remission compared with conventional regimens, and avacopan is an effective glucocorticoid-sparing option. In contrast, there is not compelling evidence to support the routine use of plasma exchange in addition to standard remission-induction therapy in AAV. ANCA and other biomarkers can be helpful in association with clinical assessment to guide diagnosis and treatment decisions. Patients should be frequently evaluated during follow-up for possible disease relapses or treatment-related morbidity, and for monitoring damage accrual, especially metabolic and cardiovascular damage.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are a group of multisystemic autoimmune diseases characterized by necrotizing inflammation of small vessels. Kidney involvement is frequent in granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), and accounts for a significant proportion of the morbidity and mortality related to these diseases. Despite improvement in therapeutic management of ANCA-glomerulonephritis (ANCA-GN), end-stage kidney disease (ESKD) still occurs in up to 30% of affected patients within 5 years following diagnosis. Thus, identifying patients for whom aggressive immunosuppressive therapy will be more beneficial than deleterious is of great importance. Several clinical, biological and histological factors have been proposed as predictors of ESKD. The kidney biopsy is essential not only for the diagnosis, but also for evaluating renal prognosis. In this review, we discuss the prognostic value of renal lesions at the diagnosis of ANCA-GN by analyzing each compartment of the nephron. We also review existing ESKD risk classification in ANCA-GN and finally propose an example of a standardized pathology report that could be used in routine practice.

Abstract
Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is a destructive small vessel vasculitis affecting multiple organs. Renal involvement often leads to end-stage renal disease and increases mortality. Prompt diagnosis and initiation of adequate immunosuppressive therapy are critical for the best patient and kidney outcomes. However, considerable heterogeneity in symptoms and severity across the patients frequently hinder the diagnosis and management. The objective of this review is to emphasize the heterogeneity of the ANCA-associated vasculitis, facilitate the recognition and give guidance to the therapeutical possibilities. We present epidemiologic and risk factors, pathogenesis, and provide comprehensive clinical features of the disease. This article also focuses on the currently available therapeutic options and emerging cellular and molecular targets for the management of systemic and especially renal disease. We conducted extensive literature research published on PubMed and Google Scholar. We systematically reviewed, analyzed, and assembled databases, covering a broad spectrum of aspects of the disease. We compared and summarized the recommendations of two recent guidelines on ANCA-associated vasculitis. The incidence of ANCA-associated vasculitis, hence glomerulonephritis shows a steady increase. Familiarity with the presenting symptoms and laboratory abnormalities are necessary for rapid diagnosis. Early initiation of treatment is the key aspect for favorable patient and renal outcomes. A better understanding of the pathogenesis constantly leads to more targeted and therefore more efficient and less toxic treatment.

Abstract
Objectives Diagnosing patients with ANCA-associated vasculitis (AAV) can be challenging owing to
its rarity and complexity. Diagnostic delay can have severe consequences, such as
chronic organ damage or even death. Given that few studies have addressed diagnostic
pathways to identify opportunities to improve, we performed a clinical audit to evaluate
the diagnostic phase. Methods This retrospective, observational study of electronic medical records data in hospitals
focused on diagnostic procedures during the first assessment until diagnosis. Results We included 230 AAV patients from nine hospitals. First assessments were mainly
performed by a specialist in internal medicine (52%), pulmonology (14%), ENT (13%) or
rheumatology (10%). The overall median time to diagnosis was 13 [interquartile range:
2–49] days, and in patients primarily examined by a specialist in internal medicine it
was 6 [1–25] days, rheumatology 14 [4–45] days, pulmonology 15 [5–70] days and ENT 57
[16–176] days (P = 0.004). Twenty-two of 31 (71%) patients primarily
assessed by a specialist in ENT had non-generalized disease, of whom 14 (64%) had
ENT-limited activity. Two hundred and nineteen biopsies were performed in 187 patients
(81%). Histopathological support for AAV was observed in 86% of kidney biopsies, 64% of
lung biopsies and 34% of ENT biopsies. Conclusion In The Netherlands, AAV is diagnosed and managed predominantly by internal medicine
specialists. Diagnostic delay was associated with non-generalized disease and ENT
involvement at presentation. Additionally, ENT biopsies had a low diagnostic yield, in
contrast to kidney and lung biopsies. Awareness of this should lead to more frequent
consideration of AAV and early referral for a multidisciplinary approach when AAV is
suspected.

Abstract
The ANCA associated vasculitides (AAVs) affect a range of internal organs including ear nose and throat, respiratory tract, kidneys, skin and nervous system. They include granulomatosis with polyangiitis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA) and microscopic polyangiitis (MPA). The AAVs are treated with high dose glucocorticoids, immunosuppressants, and targeted biological medications. Since the 1990s classification criteria for the AAVs have been based on clinical features, laboratory tests and basic imaging; an initiative to update the classification criteria incorporating newer tests, for example, anti-neutrophil cytoplasmic antibodies (ANCA) and novel imaging techniques will be published this year. There is also evidence for classification of patients based on ANCA subtype; those with anti-proteinase 3 antibodies (PR3) or anti-myeloperoxidase antibodies (MPO) have differences in response to treatment and clinical outcomes. An update is described within this review. The pathogenesis of AAV involves necrotizing inflammation of small to medium blood vessels involving multiple immunological pathways. We present an update on emerging evidence related to auto-antibodies, complement and lymphocyte pathways. This review describes emerging treatment regimens, including evidence for plasma exchange in severe disease and the inhibitor of the complement C5a receptor (C5aR) inhibitor, Avacopan. Lastly, patient reported outcomes are key secondary outcomes in randomised controlled trials and increasingly clinical practice, we report development in disease specific and glucocorticoid-specific PROs.

Abstract
Granulomatosis with polyangiitis (GPA), formerly named Wegner’s granulomatosis is an antineutrophilic cytoplasmic antibody (ANCA) associated vasculitis of the small vessels. GPA can affect several organ systems even though predominantly affects respiratory and renal systems. Pathogenesis is initiated by activation of the immune system to produce ANCA, Cytoplasmic (C-ANCA) antibody, which thereby leads to widespread necrosis and granulomatous inflammation. Multisystem involvement with varied symptomatology makes GPA diagnosis more challenging. Early diagnosis and management are vital and can alter the prognosis of the disease. We present a literature review and a clinical scenario of a 26-year-old male with a history of chronic sinusitis, testicular carcinoma in remission, recent onset of worsening cough, epistaxis, hoarseness of voice, weight loss, and dark-colored urine. Workup revealed high titers of C-ANCA, C-reactive protein, procalcitonin, CT chest evidence of mass-like consolidation, and bronchoscopy findings of friable tissue that was not amenable for biopsy. Methylprednisolone and rituximab (RTX) were administered, which resulted in marked clinical improvement. Therefore, a keen eye for details is necessary to diagnose GPA early, which can improve disease outcomes dramatically.

Association between biopsies for anti-neutrophil cytoplasmic antibody-associated vasculitis and prognosis: a retrospective cohort study. Clin Rheumatol 2021; 41:541-548. [PMID: 34505212 DOI: 10.1007/s10067-021-05889-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 08/04/2021] [Accepted: 08/16/2021] [Indexed: 01/01/2023]
Abstract
OBJECTIVES Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic vasculitis with unknown aetiology. Although biopsies are helpful for diagnosing AAV, whether they improve the outcomes of AAV patients remains unknown. The objective of this study was to elucidate the association between biopsies and prognosis. METHOD This retrospective cohort study analysed health care records that were routinely collected at 190 hospitals in Japan from April 2005 to March 2019. Patients who were 18 years or older and hospitalized for AAV were eligible for inclusion. The primary outcome was the composite outcome of death and renal replacement therapy (RRT) during the first admission. We compared the outcome between the biopsy group and the no-biopsy group. The chi-square test was performed as a univariable analysis, and logistic regression analysis was performed as a multivariable analysis. RESULTS Three hundred and eighty-six patients were assessed in this study. One hundred fifty-four (39.9%) patients underwent biopsy, and 232 (60.1%) patients did not undergo biopsy during the first admission with AAV. In univariable analysis, the composite outcome of death and RRT were observed in 7 (4.5%) patients in the biopsy group and 25 (10.8%) patients in the no-biopsy group (OR 0.39 [95% CI 0.17, 0.94], P = 0.01). The result was consistent in the multivariable analysis (OR 0.31 [95% CI 0.12, 0.79], P = 0.01) after adjusting for potential confounders. CONCLUSIONS We showed that patients who underwent biopsy had a better prognosis in the composite outcome of mortality and RRT during admission using a Japanese healthcare record database. Key Points • This is the first study to elucidate the association between undergoing biopsy and prognosis. • Patients undergoing biopsy had a better prognosis in the composite outcome of mortality and RRT. • The proportion of patients who received transfusions was not significantly different between the two groups.

Abstract
Background Kidney biopsy is valuable for prognostic assessment of renal outcomes in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) with glomerulonephritis (AAV-GN) but the impact of chronic changes is not determined. Methods We conducted a retrospective cohort study of myeloperoxidase (MPO)- or proteinase 3 (PR3)-ANCA-positive patients with AAV and active renal disease. We applied the Mayo Clinic Chronicity Score (MCCS) and validated and evaluated its implications on outcome prediction in AAV-GN. Results We analyzed 329 patients with kidney biopsies available to score. The extent of chronicity was graded by MCCS as minimal [102 (31.0%)], mild [106 (32.2%)], moderate [86 (26.1%)] and severe [35 (10.6%)]. The MCCS grades correlated with the degree of renal function impairment at presentation [mean estimated glomerular filtration rate (eGFR) 48.3 versus 29.2 versus 23.7 versus 18.5 mL/min/1.73 m2, respectively; P < 0.0001]. Higher degrees of the individual components of the MCCS (glomerulosclerosis, interstitial fibrosis, tubular atrophy and arteriosclerosis) were associated with lower median eGFR (P < 0.0001) and decreased event-free [kidney failure (KF) and death] survival (P = 0.002, P < 0.0001, P < 0.0001 and P = 0.017, respectively). Patients with lower MCCS grades recovered renal function more frequently (P < 0.0001). Increasing MCCS grades were associated with decreased renal recovery (P = 0.001), more frequent events and shorter time to KF (P < 0.0001), KF and death (P < 0.0001) and death (P = 0.042), independent of the remission induction treatment used (cyclophosphamide or rituximab). The MCCS stratified renal outcomes for each MCCS grade and can be used in clinical practice as a cutoff for KF prediction (MCCS ≥4). Conclusions Chronic changes on kidney histology independently predict renal function, outcomes and response to treatment in AAV-GN.

Abstract
Acute kidney injury (AKI) is increasingly emerging as a global emergency. Sepsis, major surgery, and nephrotoxic drugs are the main causes of AKI in hospitalized patients. However, glomerulonephritis accounts for about 10% of AKI episodes in adults, mainly related to rapidly progressive glomerulonephritis resulting from granulomatous polyangiitis (GPA, Wegener granulomatosis), microscopic polyangiitis (MPA), and anti-glomerular basement membrane (GBM) disease. Also, diffuse proliferative lupus nephritis, immunoglobulin A nephropathy, post-streptococcal glomerulonephritis, mixed cryoglobulinemia, mesangiocapillary glomerulonephritis, membranous nephropathy, hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, and scleroderma can induce acute renal failure. Early diagnosis of AKI due to glomerulonephritis is crucial for prompt, effective management to improve short- and long-term outcomes. Kidney biopsy is the gold standard for the diagnosis of glomerular disease, but it is not frequently performed in critically ill patients because of their clinical conditions. In this setting, a growing number of diagnostic assays can support the working hypothesis, including antineutrophil cytoplasmic antibodies (ANCAs), anti-double-stranded DNA antibodies, anti-GBM antibodies, antistreptolysin O and anti-DNase B antibodies, cryoglobulins, antiphospholipid antibodies, and complement levels. Therapeutic strategies in AKI patients with glomerulonephritis include high-dose corticosteroids, cyclophosphamide, and plasma exchange. This article reviews the wide spectrum of glomerulopathies associated with AKI, describing the immunological mechanisms underlying glomerular diseases and presenting an overview of the therapeutic options.

Abstract
BACKGROUND AND OBJECTIVES The histopathologic classification for ANCA-associated GN distinguishes four classes on the basis of patterns of injury. In the original validation study, these classes were ordered by severity of kidney function loss as follows: focal, crescentic, mixed, and sclerotic. Subsequent validation studies disagreed on outcomes in the crescentic and mixed classes. This study, driven by the original investigators, provides several analyses in order to determine the current position of the histopathologic classification of ANCA-associated GN. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A validation study was performed with newly collected data from 145 patients from ten centers worldwide, including an analysis of interobserver agreement on the histopathologic evaluation of the kidney biopsies. This study also included a meta-analysis on previous validation studies and a validation of the recently proposed ANCA kidney risk score. RESULTS The validation study showed that kidney failure at 10-year follow-up was significantly different between the histopathologic classes (P<0.001). Kidney failure at 10-year follow-up was 14% in the crescentic class versus 20% in the mixed class (P=0.98). In the meta-analysis, no significant difference in kidney failure was also observed when crescentic class was compared with mixed class (relative risk, 1.15; 95% confidence interval, 0.94 to 1.41). When we applied the ANCA kidney risk score to our cohort, kidney survival at 3 years was 100%, 96%, and 77% in the low-, medium-, and high-risk groups, respectively (P<0.001). These survival percentages are higher compared with the percentages in the original study. CONCLUSIONS The crescentic and mixed classes seem to have a similar prognosis, also after adjusting for differences in patient populations, treatment, and interobserver agreement. However, at this stage, we are not inclined to merge the crescentic and mixed classes because the reported confidence intervals do not exclude important differences in prognosis and because an important histopathologic distinction would be lost.

Abstract
Vasculitis is characterized by inflammation of the vascular wall. It reaches vessels of different sizes and locations, conditioning multisystem and complex manifestations that require a holistic approach. Antineutrophil cytoplasmic antibody-associated vasculitis has an annual incidence rate of 20 per million inhabitants. It is the result of the interaction of infectious, genetic and environmental factors and manifest itself with varied and unspecific symptoms, often reaching the general state, respiratory and renal systems. The combination of clinical, laboratory, imaging and fundamentally histological changes allows the diagnosis and classification of the extent / severity of the disease necessary for the decision of the therapeutics to be taken. Glucocorticoids are generally used; with methotrexate being considered when localized disease and cyclophosphamide, rituximab or azathioprine when generalized disease. A systematized approach can increase survival rates from 12% to 70% over a 5-year span.

Abstract
ENT involvement is common in ANCA-associated vasculitis (AAV), particularly in GPA and EGPA. Early recognition and treatment is important for good outcomes, yet evidence suggests that UK ENT surgeons may not consistently recognise the early features of AAV, despite a similar incidence to vestibular schwannoma. AAV is a rapidly advancing field, with significant developments in the understanding of its pathogenesis, classification and treatment over the past decade. Relevant vasculitis mimics are also discussed with a particular focus on the increasing prevalence of vasculitis mimics driven by an increase in recreational cocaine use, as well as the emergence and reclassification of several other vasculitis mimics in the head and neck. This article reviews key recent updates in the vasculitis literature, with a particular focus on those relevant to recognition and diagnosis of AAV for the ENT surgeon. Strengths and limitations of relevant diagnostic testing are discussed, and a method of evaluation of patients with features of AAV presenting to ENT services is outlined.

Abstract
ANCA-associated vasculitis (AAV) may lead to irreversible organ damage, particularly end-stage renal disease (ESRD) requiring dialysis. The chances of renal recovery diminish with prolonged dialysis. We describe a case of a 32-year-old woman admitted for pulmonary infiltrates and acute renal failure. Autoimmune workup revealed an elevated titer of proteinase 3-antineutrophil cytoplasmic antibody (PR3-ANCA). The diagnosis of granulomatosis with polyangiitis (GPA) was confirmed by renal biopsy. The patient received induction therapy with IV rituximab (375 mg/m2 per week for 4 weeks) along with systemic high-dose IV corticosteroids and one pulse of IV cyclophosphamide (1000 mg). Rapid deterioration of her kidney function led to pulmonary edema requiring intensive care (ICU) hospitalization. Dialysis and plasmapheresis were initiated. Significant clinical improvement ensued, but the patient remained dialysis dependent. No immunosuppressive maintenance therapy other than prednisone was given. Chronic dialysis was discontinued successfully after eight months. At a follow-up of 30 months since her hospitalization, the patient is in complete remission without relapses. We suggest that rituximab induction without maintenance therapy for GPA ESRD may be adequate.

Abstract
Background Classification of patients with anti-neutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN) into histological classes is useful for predicting a patient's risk of progression to end-stage renal disease (ESRD). However, even in the worst prognostic group, the 5-year end-stage renal disease-free survival rate is as high as 50%. Objectives To investigate those prognostic factors indicative of progression to ESRD in patients with ANCA-GN and sclerosing histology. Methods Patients from the Norwegian Kidney Biopsy Registry between 1991 and 2012 who had biopsy verified pauci-immune glomerulonephritis, positive ANCA serology, and sclerosing histology were included. Cases with ESRD during follow-up were identified via linkage with the Norwegian Renal Registry. Potential prognostic factors with relevant cut-offs were compared in patients with and without progression to ESRD during follow-up. Results Of 23 included patients, 10 progressed to ESRD. ESRD patients had a lower initial estimated glomerular filtration rate (eGFR; 21 versus 52 ml/min/1.73 m2) and a lower percentage of normal glomeruli (4% versus 15%). Five-year risks of ESRD with eGFR >15 versus ≤15 ml/min/1.73 m2 were 77% and 15%, with percentage normal glomeruli >10% versus ≤10%, 83% and 39%. Conclusions eGFR and percentage of normal glomeruli are strong risk factors for ESRD in ANCA-GN with sclerosing histology.

[PMID: 29955611 PMCID: PMC6000915 DOI: 10.1155/2018/7581567] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 04/03/2018] [Accepted: 05/07/2018] [Indexed: 12/03/2022]
Abstract
Background The value of a histologic classification scheme to classify patients with anti-neutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN) into focal, mixed, crescentic, and sclerotic types for predicting risk of end-stage renal disease (ESRD) is well documented. However, the prognostic value of histological classification specifically in elderly patients (≥70 years) with ANCA-GN has not previously been investigated. Methods Patients with biopsy-verified pauci-immune necrotizing glomerulonephritis were identified from the Norwegian Kidney Biopsy Registry between 1991 and 2012 and those ≥70 years of age at the time of diagnosis and having positive anti-neutrophil cytoplasmic antibody serology were included in this study. The incidence rate of ESRD and/or death was determined by linking the study cohort to the Norwegian Renal Registry and the Population Registry of Norway. The ESRD-free survival and patient survival were compared between the 4 histological types. Results Of the 81 patients included, 20 progressed to ESRD and 34 died. The 1-year and 5-year ESRD-free survival varied between histological groups (p = 0.003) as follows: focal, 97% and 97%, respectively; mixed, 70% and 57%; crescentic, 76% and 63%; and sclerotic, 49% and 49%. Patient survival did not differ significantly between groups (p = 0.30). Conclusion Histological classification in elderly patients with ANCA-GN is useful for predicting ESRD but not survival.

Abstract
Background End-stage renal disease (ESRD) risk in patients with antineutrophil cytoplasmic antibody- (ANCA-) associated glomerulonephritis (ANCA-GN) according to ANCA serotype and stratified by histological classification has not been previously investigated. Methods Patients from the Norwegian Kidney Biopsy Registry (NKBR) between 1991 and 2012 who had biopsy-verified pauci-immune glomerulonephritis and positive antineutrophil cytoplasmic antibody serology were included. Cases with ESRD during follow-up were identified in the Norwegian Renal Registry. ESRD-free survival with proteinase 3 (PR3) versus myeloperoxidase- (MPO-) ANCA positivity stratified into 4 histological classes was investigated. Results Three hundred fifty-eight patients, of whom 87 progressed to ESRD during follow-up, were included. Patients with PR3- as compared to MPO-ANCA were younger (58 versus 64 years, p = 0.001), had a higher percentage of males (62 versus 41%, p < 0.001), had a lower percentage with a sclerozing glomerulonephritis pattern (4 versus 16%, p < 0.001), and had a significantly higher cumulative ESRD-free survival (90 versus 80%, p = 0.007) at 1-year follow-up. No significant differences in cumulative ESRD-free survival with PR3- as compared to MPO-ANCA were observed by histological stratification. Conclusion Advanced glomerular sclerosis is found more frequently in patients with MPO-ANCA, explaining the higher risk of ESRD. ANCA serotypes have no impact on prognosis of patients with similar histological findings.

Abstract
PURPOSE Sex-specific differences in the risk of end-stage renal disease (ESRD) in patients with anti-neutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN) stratified by histological classification have not been previously investigated. METHODS Patients with biopsy-verified pauci-immune necrotizing GN and positive ANCA serology in the Norwegian Kidney Biopsy Registry between 1991 and 2012 were included. Patients with ESRD during follow-up were identified from the Norwegian Renal Registry. ESRD-free survival stratified by histological classifications was investigated. RESULTS We analyzed 358 patients, of whom 87 progressed to ESRD during follow-up. Overall ESRD-free survival at 1 and 5 years in the entire cohort was 81 and 71% in males versus 90 and 80% in females, respectively; 94 and 84% in males versus 98 and 98% in females with focal histology, respectively; 85 and 76% in males versus 89 and 77% in females with mixed histology, respectively; 72 and 58% in males versus 90 and 78% in females with crescentic histology, respectively; and 52 and 46% in males versus 60 and 38% in females with sclerotic histology, respectively. Males had an increased risk of ESRD (adjusted hazard ratio, 2.44 [1.56-3.82]; p < 0.001). CONCLUSION Male sex is associated with increased risk of ESRD across all histological classes of ANCA-GN.

Abstract
BACKGROUND Immunosuppressive therapy for antineutrophil cytoplasmic antibody-associated vasculitis has been associated with increased malignancy risk. OBJECTIVES To quantify the cancer risk associated with contemporary cyclophosphamide-sparing protocols. METHODS Patients from the Norwegian Kidney Biopsy Registry between 1988 and 2012 who had biopsy-verified pauci-immune glomerulonephritis and positive antineutrophil cytoplasmic antibody (ANCA) serology were included. Standardised incidence ratios (SIRs) were calculated to compare the study cohort with the general population. RESULTS The study cohort included 419 patients. During 3010 person-years, cancer developed in 41 patients (9.79%); the expected number of cancer cases was 37.5 (8.95%). The cohort had SIRs as follows: 1.09, all cancer types (95% CI, 0.81 to 1.49); 0.96, all types except nonmelanoma skin cancer (95% CI, 0.69 to 1.34); 3.40, nonmelanoma skin cancer (95% CI, 1.62 to 7.14); 3.52, hematologic cancer (95% CI, 1.32 to 9.37); 2.12, posttransplant cancer (95% CI, 1.01 to 4.44); and 1.53, during the 1-5-year follow-up after diagnosis (95% CI, 1.01 to 2.32). CONCLUSIONS Cancer risk did not increase significantly in this cohort with ANCA-associated glomerulonephritis. However, increased risk of nonmelanoma skin cancer, posttransplant cancer, and hematologic cancer indicates an association between immunosuppression and malignancy.

Abstract
BACKGROUND Immunopathologic features predict renal function at baseline and follow-up in antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN). The interstitial infiltrate consists predominantly of T lymphocytes, but their pathophysiologic significance is unclear, especially in light of the success of B-cell-directed therapy. METHODS Renal biopsies from 33 patients treated with cyclophosphamide (CYC; n = 17) or rituximab (RTX; n = 16) in the RTX in ANCA-associated vasculitis (RAVE) trial were classified according to the new ANCA GN classification. T- and B-cell infiltration in the interstitium was assessed by immunostaining for CD3 and CD20. Correlations of clinical and histologic parameters with renal function at set time points were examined. RESULTS The mean (SD) baseline estimated glomerular filtration rate was 36 (20) mL/min/1.73 m2. ANCA GN class distribution was 46% focal, 33% mixed, 12% sclerotic and 9% crescentic. The interstitial infiltrate consisted of >50% CD3 positive cells in 69% of biopsies, but >50% CD20 positive cells only in 8% of biopsies. In a multiple linear regression model, only baseline glomerular filtration rate (GFR) correlated with GFR at 6, 12, and 18 months. Interstitial B- and T-cell infiltrates had no significant impact on long-term prognosis, independent of the treatment limb. A differential effect was noted only at 6 months, where a dense CD3 positive infiltrate predicted lower GFR in the RTX group and a CD20 positive infiltrate predicted higher GFR in the CYC group. CONCLUSIONS In ANCA-associated GN, the interstitial infiltrate contains mainly T lymphocytes. However, it is neither reflecting baseline renal function nor predictive of response to treatment, regardless of the immunosuppression regimen employed.

Abstract
Vasculitides comprise several diseases affecting vessels of different sizes, mainly arteries, but also capillaries and veins. Antineutrophil cytoplasm antibody-associated vasculitides (AAVs) belong to the systemic necrotizing small-vessel vasculitis group that comprises granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. Internists often see AAV patients, and although their outcomes are usually good, the disease can be responsible for morbidity and mortality. Herein, after reviewing the literature, we concentrate on selected aspects important for the internist, including classification, diagnostic dilemmas, treatment novelties, and follow-up.

Abstract
PURPOSE To evaluate significance of clinical and histopathological prognostic factors for renal and patient outcome in AAV patient cohort. METHODS Retrospective study included consecutive patients diagnosed with pauci-immune crescentic glomerulonephritis from January 2003 to December 2013. Primary outcome was combined endpoint patient death or progression to end-stage renal disease (ESRD). Secondary outcomes were patient survival and progression to ESRD (renal survival) singularly and disease relapse. Kaplan-Meyer survival analysis and multivariate Cox proportional hazard regression analysis were used to explore difference between phenotypes and finding significant predictors regarding outcomes. RESULTS Out of 81 patients, 40.7% patients reached primary endpoint, 22.2% died, 29.6% reached ESRD and 16% relapsed during follow-up. Multivariate Cox proportional hazards regression-adjusted analysis found higher BVAS (HR 1.08, 95% CI 1.01-1.17, p = 0.042), higher baseline maximal serum creatinine (HR 1.02, 95% CI 1.01-1.03, p = 0.04) and lower haemoglobin (HR 0.97, 95% CI 0.95-0.99, p = 0.011) significantly associated with primary endpoint. Higher BVAS (HR 1.25, 95% CI 1.01-1.43, p = 0.001) and lower haemoglobin (HR 0.95, 95% CI 0.91-0.99, p = 0.008) were significantly associated with patient survival, while for renal survival, lower haemoglobin (HR 0.97, 95% CI 0.94-0.99, p = 0.041) and the need for acute haemodialysis (HR 3.15, 95% CI 1.20-8.26, p = 0.02) were significant predictors. On multivariate-adjusted analysis, no significant predictors for disease relapse were found. Kaplan-Meier survival analysis found no difference between clinical, serological and pathohistological phenotypes for all of the endpoints. CONCLUSIONS Renal function at presentation, anaemia and BVAS should be included in prediction models for the outcomes for the AAV patients.

Abstract
Context.—Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis commonly presents with pulmonary and renal involvement that may present diagnostic challenges.
Objectives.—To highlight the updates in the classification of small vessel vasculitis, present the patterns of pulmonary and renal pathology in which ANCA-associated vasculitis is included in the differential diagnosis, analyze the screening and specific antineutrophil cytoplasmic antibody testing methods in the clinical laboratory, compare and contrast the 3 major ANCA-associated vasculitis diseases, and review the pathophysiologic mechanisms of tissue injury in this setting.
Data Sources.—Data are derived from published literature and clinical experience.
Conclusions.—Although rare, ANCA-associated vasculitis diseases are often considered in the differential diagnosis of many pathologic patterns of pulmonary and renal disease. Histopathologic diagnosis of specific entities in this context nearly always requires correlation of the pathology with clinical and serologic data.

Abstract
Uveitic glaucoma consists one of the most serious complications of intraocular inflammation and, despite its rarity, is considered as one of the leading causes of preventable loss of vision worldwide. It has been associated with a wide spectrum of inflammatory diseases, but its pathogenesis is still not fully comprehended. It appears that the type of inflammation, the steroid-response and the anatomical alterations of the anterior chamber play a pivotal role. To our knowledge, the mechanisms may be both acute and chronic. The main targets of the treatment are to control the inflammation and reduce the intraocular pressure (IOP). The management of glaucoma associated with uveitis remains an extremely challenging condition for ophthalmologists. The successful treatment of uveitic glaucoma is inextricably correlated with prompt and immediate therapeutic decisions. Very often a solid collaboration between clinicians from different specialties may be required for treating the underlying disease. Further understanding of its pathogenesis can indicate therapeutic targets and may lead to the development of new and more efficient therapeutic approaches. New glaucoma surgical modalities may ameliorate the prognosis after surgical intervention, but this calls for further evaluation. This study aims to highlight the complexity of uveitic glaucoma analyzing the main pathogenetic mechanisms and the correlations with the inflammatory response.

Abstract
BACKGROUND AND OBJECTIVES A kidney biopsy is preferred for the diagnosis of ANCA-associated vasculitis with renal involvement. The aim of our study was to evaluate the prognostic value of a histopathologic classification scheme recently proposed by an international consortium of renal pathologists in a large Norwegian cohort. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients diagnosed with ANCA-associated GN were included from the Norwegian Kidney Biopsy Registry 1991-2012. Renal morphology was classified as focal, mixed, crescentic, or sclerotic. Study end point was ESRD. Patients were followed from kidney biopsy to end of 2012. RESULTS Two hundred fifty patients with ≥10 glomeruli in the biopsy were included in our study. During a median follow-up of 3.5 years (0.7-7.6), 60 cases of ESRD occurred. Ninety-six (38%) biopsies were classified as focal, 61 (24%) biopsies were classified as mixed, 71 (28%) biopsies were classified as crescentic, and 22 (9%) biopsies were classified as sclerotic; 1- and 5-year cumulative renal survival rates were 96% and 90%, respectively, for the focal class, 86% and 75%, respectively, for the mixed class, 81% and 69%, respectively, for the crescentic class, and 56% and 51%, respectively, for the sclerotic class. By multivariate Cox regression analyses, the sclerotic class had a significantly worse renal prognosis than the focal (hazard ratio, 9.65; 95% confidence interval, 2.38 to 39.16) or combined mixed/crescentic classes (hazard ratio, 3.27; 95% confidence interval, 1.41 to 7.61), but no significant differences in outcome were observed in the crescentic class compared with the mixed class (hazard ratio, 1.13; 95% confidence interval, 0.44 to 2.87) or the combined mixed/crescentic class compared with the focal class (hazard ratio, 1.93; 95% confidence interval, 0.61 to 6.12). Accuracy by receiver operator characteristic curve analysis was estimated to be 0.72 (95% confidence interval, 0.65 to 0.80). In 108 additional patients with three to nine glomeruli in the biopsy, the prognostic value of this classification scheme was unchanged. CONCLUSIONS The histopathologic classification is a predictor of renal outcome of moderate quality. Merging the mixed and crescentic classes in the future could simplify the scheme.

Abstract
Interstitial Lung Disease Program, National Jewish Medical and Research Center, Division of Pulmonary Sciences and Critical Care Medicine, University of Colorado Health Sciences Center, Denver, Colorado, USA The diagnosis and management of SVV remains one of the most challenging clinical scenarios encountered by a clinician. Careful attention to detail and a thorough knowledge of the specific disorders, their therapies, and complications thereof is required to optimally care for these patients. The recent completion of a number of randomized, controlled, multicenter clinical trials has greatly improved our knowledge base and ability to care for vasculitis patient. The next decade holds even more promise.

Abstract
In this article, the 2009 European League Against Rheumatism (EULAR) recommendations for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) have been updated. The 2009 recommendations were on the management of primary small and medium vessel vasculitis. The 2015 update has been developed by an international task force representing EULAR, the European Renal Association and the European Vasculitis Society (EUVAS). The recommendations are based upon evidence from systematic literature reviews, as well as expert opinion where appropriate. The evidence presented was discussed and summarised by the experts in the course of a consensus-finding and voting process. Levels of evidence and grades of recommendations were derived and levels of agreement (strengths of recommendations) determined. In addition to the voting by the task force members, the relevance of the recommendations was assessed by an online voting survey among members of EUVAS. Fifteen recommendations were developed, covering general aspects, such as attaining remission and the need for shared decision making between clinicians and patients. More specific items relate to starting immunosuppressive therapy in combination with glucocorticoids to induce remission, followed by a period of remission maintenance; for remission induction in life-threatening or organ-threatening AAV, cyclophosphamide and rituximab are considered to have similar efficacy; plasma exchange which is recommended, where licensed, in the setting of rapidly progressive renal failure or severe diffuse pulmonary haemorrhage. These recommendations are intended for use by healthcare professionals, doctors in specialist training, medical students, pharmaceutical industries and drug regulatory organisations.

Abstract
In the early 1990s, an international working group of experienced renal pathologists, the Renal Histology group, set up a scoring system for biopsies with anti-neutrophil cytoplasmic autoantibody (ANCA)-associated glomerulonephritis. This scoring system subdivided glomerular, interstitial and vascular lesions and served as a tool for the evaluation of all renal biopsies from studies of the European Vasculitis Study Group (EUVAS). Histopathological studies gave new insights into the prediction of renal outcome in patients with ANCA-associated glomerulonephritis. Percentage of normal glomeruli and a selected number of interstitial parameters were reliable predictors of long-term follow-up glomerular filtration rate in all studies. Out of these results, a histopathological classification distinguishing focal, crescentic, mixed and sclerotic classes of ANCA-associated glomerulonephritis was developed. Until today, 13 studies have validated this classification system. Future studies will try to determine if and how renal histology could be helpful in guiding treatment of ANCA-associated glomerulonephritis.

Abstract
BACKGROUND AND OBJECTIVES A proposed histopathologic classification for ANCA-associated GN is predictive of long-term renal outcome in adult populations. This study sought to validate this system in a pediatric cohort. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This was a retrospective, single-center, cohort study of 40 children diagnosed and followed until their transition to adult care at one institution between 1987 and 2012. Renal biopsy specimens were reviewed by a pathologist blinded to patient outcome and were classified using the new histopathologic classification system of focal, crescentic, mixed, and sclerotic groups. Time to the composite outcome of CKD stages 3 and 4 (determined by eGFR with repeated creatinine measures using the Schwartz equation) or ESRD (defined as dialysis dependence or transplantation) were ascertained. RESULTS The study population consisted of 40 children (70% female), followed for a median of 2.4 years. The biopsy specimens were categorized as focal in 13 patients (32.5%), crescentic in 20 (50%), mixed in two (5%), and sclerotic in five (12.5%). Mixed and crescentic were combined for analyses. Survival analysis of time to the composite renal endpoint of at least 3 months of eGFR<60 ml/min per 1.73 m(2) or ESRD differed significantly among the three biopsy groups log-rank P<0.001), with an adjusted hazard ratio of 3.14 (95% confidence interval, 0.68 to 14.4) in the crescentic/mixed group and 23.6 (95% confidence interval, 3.9 to 144.2) in the sclerotic category compared with the focal category. The probability of having an eGFR>60 ml/min per 1.73 m(2) at 2 years was 100% for the focal, 56.5% for the crescentic/mixed, and 0% for the sclerotic biopsy categories. CONCLUSIONS This study showed the clinical utility of this histopathologic classification system and its ability to discriminate renal outcomes among children with ANCA GN.

Abstract
BACKGROUND Histopathological lesions in renal biopsy (RB) at presentation of ANCA-associated vasculitis (AAV) have been described in depth but repeat protocolized renal biopsies are seldomly performed in AAV. In this study, we present a group of AAV patients with repeat protocolized biopsies, and we evaluate their clinical significance. METHODS A total of 17 consecutive patients diagnosed between 1991 and 1995 with AAV and renal involvement confirmed by biopsy at presentation in a single center underwent a protocol planned rebiopsy in remission after a median of 13 months (range 11-28) from diagnosis. Biopsies were assessed by two independent pathologists, blinded to patient data. Clinical data were collected retrospectively. RESULTS Patients were followed-up for a median of 189 months from diagnosis. Renal relapse was observed in eight patients (47.1%), seven patients died, three patients reached end-stage renal failure. There was a significant decrease in the percentage of acute lesions (cellular crescents, fibrinoid necrosis, P < 0.001) and a significant increase in chronic lesions (glomerulosclerosis, interstitial fibrosis, P ≤ 0.01) in the repeat RB compared with the first RB. This resulted in a class change over the biopsies within most patients. The percentage of normal glomeruli in the first biopsy positively correlated with estimated GFR at the end of follow-up (rs = 0.509, P = 0.05). CONCLUSIONS This is the first study on protocolized repeat biopsies in AAV, giving insight into disease activity under immunosuppressive treatment. Apparently, many AAV patients have grumbling disease with ongoing activity, eventually leading to an increased amount of chronic lesions.

Abstract
Granulomatosis with polyangiitis (GPA), previously referred to as Wegener's granulomatosis, is a rare necrotizing granulomatous vasculitis, especially in children. GPA affects small- to medium-sized vessels, leading to involvement of multiple organs, including the upper and lower respiratory tracts and kidneys. Glomerular lesions associated with GPA typically present as crescentic glomerulonephritis with necrotizing lesions, with little or no staining for immunoglobulins and complement proteins. We report a unique pediatric case of GPA associated with IgA nephropathy, a representative immune-mediated glomerular disease. The initial renal biopsy specimen revealed fibrous sclerosis and mild mesangial proliferation without deposition of IgA. However, after clinical remission of GPA by treatment, the serum IgA level continued to be significantly higher than normal, and her paranasal sinusitis was poorly controlled. An acute upper respiratory infection resulted in worsened urinary findings without any systemic signs of GPA. The second renal biopsy specimen revealed deposition of IgA and C3 in the mesangium. The patient was treated with oral prednisolone alone, which led to complete remission of proteinuria within 1 month. IgA nephropathy is possibly associated with GPA during remission stage, and serum IgA level may be a valuable indicator to predict its association.

Abstract
Background Renal biopsies provide important diagnostic and prognostic information in ANCA associated glomerulonephritis. A new classification for prognostication of pauci-immune glomerulonephritis (GN) based on four categories (Mixed, Crescentic, Sclerotic and Focal) was proposed by an international working group of renal pathologists (IWGRP). The goal of our study was to apply the proposed classification system to a United States cohort of vasculitis patients and determine the association of IWGRP class with estimated glomerular filtration rate (eGFR) at one year. Methods Seventy-six cases of pauci-immune glomerulonephritis diagnosed from 1995 to 2011 from a single center were identified for this retrospective study. Clinical data were collected by abstraction from medical records. Histology was reviewed by a pathologist and classified according to the new classification. MDRD formula was used to calculate eGFR. We correlated IWGRP class to renal function at presentation and at one year. ×2, ANOVA, and linear regression analysis were performed as appropriate. Results Renal biopsies were categorized as focal: n = 20, crescentic: n = 18, mixed: n = 27, sclerotic: n = 11. The baseline e-GFR was lowest in the crescentic class and highest in the focal class. In linear regression analysis investigating e-GFR at 1 year; age and baseline e-GFR were independent predictors of e-GFR at 1 year. Conclusions The e-GFR at diagnosis and age were predictors of e-GFR at 1 year. Pathologic class at diagnosis may also be a helpful tool in risk stratification at diagnosis.

Abstract
Granulomatosis with polyangiitis (GPA), also known as Wegener's granulomatosis, is a rare disease in childhood. Of 39 GPA patients that we diagnosed during a 20-year period, only 3 (7.7%) were younger than 18 years. We report the course of GPA in three girls whose disease started at the ages of 16, 11, and 6 years. All had cutaneous manifestations: the first had necrotizing vasculitis, the second had palpable purpura, and the third had right upper-eyelid edema and infiltration and proptosis caused by extraocular pseudotumor, initially histologically misdiagnosed as orbital immunoglobulin G4 (IgG4)-related disease. Unlike with skin vasculitis and glomerulonephritis, upper-airway and orbital inflammation were resistant to immunosuppressive therapy. Our report emphasizes that children presenting with cutaneous vasculitis, chronic eyelid swelling, sinusitis, or hoarseness should be tested for antineutrophil cytoplasmic antibodies. We emphasize that the upper-eyelid edema and infiltration, with histologic characteristics of orbital IgG4-related disease, may be the initial presentation of localized GPA in children, a feature that, until now, has been described only in adults.

Abstract
Wegener's granulomatosis (WG) is an idiopathic, systemic inflammatory disease characterized by necrotizing granulomatous inflammation and pauci-immune small-vessel vasculitis of upper and lower respiratory tract and kidneys. The condition affects both genders equally, although some inconsistent gender differences have been observed. The aetiology of WG remains unknown although a number of exogenous factors have been suggested to be of aetiological relevance. Most clinical characteristics of this disease are non-specific, making clinical diagnosis challenging. Histopathological examination of lesional and peritoneal tissue is not pathognomonic, but is an essential investigation to confirm the presence of disease and exclude other disorders. At present, despite the increasingly wide range of potential therapies, cyclophosphamide plus corticosteroids remain the most recognized and effective means of inducing and sustaining remission of WG.

CONTEXT Vasculitis is a clinicopathological entity characterized by inflammation and necrosis of blood vessels. EVIDENCE ACQUISITIONS Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. RESULTS Two major autoantigens for ANCA are myeloperoxidase (MPO) and proteinase 3 (PR3), which are proteins in the primary granules of neutrophils and in the lysosomes of monocytes. They are expressed in mature neutrophils of patients with ANCA, while absent in healthy subjects. CONCLUSIONS The kidney is the most commonly affected vital organ in ANCA-associated vasculitis, and patient outcomes are largely determined by the severity of renal disease at diagnosis and by its response to treatment.

Abstract
A 60-year-old man had experienced cough, bloody sputum, and a 38 °C fever for 1.5 months. He visited an outpatient clinic and received antibiotics and nonsteroidal anti-inflammatory drugs. However, because the symptoms continued, he visited our hospital. The past medical history included chronic sinusitis, hypertension, and diabetes mellitus. A chest x-ray film and computed tomography showed multiple pulmonary nodules with cavities. Macrohematuria had developed 3 days before admission, and renal function had deteriorated (creatinine, 2.45 mg/dL) in 2 weeks. He was admitted to our hospital because of rapidly progressive glomerulonephritis (RPGN) and multiple pulmonary nodules. On admission, the clinical diagnosis was suspected to be granulomatosis with polyangiitis (Wegener's) (GPA), although tests for proteinase-3 anti-neutrophil cytoplasmic antibody (PR3-ANCA) were negative. Antibiotics were administered for 5 days. After renal biopsy, methylprednisolone pulse therapy and cyclophosphamide pulse therapy were performed. The pathological diagnosis on the basis of the renal biopsy was glomerular and interstitial hemorrhage, possibly associated with vasculitis. After the treatment, the pulmonary symptoms, multiple pulmonary nodules, and severe inflammatory reactions in the peripheral blood were resolved. However, renal dysfunction progressed to end-stage renal disease 1 month after renal biopsy. Hemodialysis was started, and the steroid therapy was continued. During hemodialysis, a second renal biopsy was performed and led to a diagnosis of pauci-immune focal segmental crescentic glomerulonephritis. Renal function gradually recovered, and hemodialysis was discontinued. This case was (double) ANCA-negative GPA which presented prominent glomerular and interstitial hemorrhage, may be associated with small vessel vasculitis, but without active necrotizing and crescentic glomerular lesions, in the rapidly progressive glomerulonephritis.

Abstract
Pulmonary-renal syndromes are a group of disorders characterised by necrotising glomerulonephritis and pulmonary haemorrhage. Small vessel systemic vasculitis is the most common cause of pulmonary-renal syndromes presenting to respiratory physicians. Rarer causes include systemic lupus erythematosus and connective tissue diseases though severe pneumonia or cardiac failure may mimic their presentation. Some forms of small vessel vasculitides have a predilection for the pulmonary and renal vascular beds and if left untreated can result in fulminant organ failure. Whilst the aetiology of these syndromes remains unclear, much is known about the disease mechanisms including the pathogenic role of autoantibodies, immune-complex mediated inflammation and microangiopathic in-situ thrombosis. Despite established treatments achieving successful remission induction, patient tolerability and side effect profiles have limited their use which has led to searches for more targeted treatments. Consequently newer biological therapies have gained wider acceptance despite little being known about their long term safety and efficacy. The European Vasculitis Study Group (EUVAS) have recently formulated guidelines to provide consensus on diagnosis and management in this area and work to define survival rates in these conditions with longer term follow-up studies is ongoing. This review summarises the current aetiopathogenesis thought to underlie these complex diseases, the diagnostic definitions and classification criteria currently in use and the evidence base for modern therapies. Though unusual for respiratory specialists to coordinate overall management of these patients, an update on their current management is regarded as important to their practice given the recently changing trends in treatments.

Abstract
Wegener’s Granulomatosis is a condition associated with systemic vasculitis which can present with upper respiratory tract symptoms initially. On September 2001, a 15-year-old girl presented with symptoms of nasal block for 3 weeks. She later developed joint pains and worsening renal status requiring dialysis. A renal biopsy was performed which showed pauci-immune cresentric glomerulonephritis. Her cANCA levels were positive. She was treated with oral cyclophosphamide and steroids and later responded.
