RESUMEN
OBJECTIVE: While the incidence and type of blood malignancies are well documented amid primary Sjögren's syndrome patients (pSS), data focusing on solid neoplasms are more conflicting. We aimed to describe clinical, pathological, and immunological characteristics of pSS patients with cancers, along with the chronological interplay between the two conditions. METHODS: Outcomes concerning both pSS and cancer were retrospectively collected from Montpellier University Hospital (tertiary center) between 2019 and 2020. pSS characteristics were compared to a control group of pSS patients without cancer. RESULTS: A total of 165 patients with pSS were included: 55 patients with cancer (52 female, mean age 58.4 ± 10.4 years at pSS diagnosis; mean follow-up 10.5 ± 10.1 years, 12 patients had multiple cancers) and 110 controls without cancer. Characteristics of pSS patients with cancers were different from controls mostly for lymphoma prognosis factors. Among the 70 cancers, we recorded 55 solid neoplasms (whom 27 breast cancers and 8 lung cancers, and 82% of adenocarcinomas), with no evidence of disease at the end of follow-up in 85% of them. Among the 15 recorded blood malignancies, ten were lymphomas with an excellent prognosis. Regarding chronological interplay between cancer and pSS, most cancers (43%) were diagnosed close (± 5 years) to pSS diagnosis. Breast cancers were diagnosed before or close to pSS diagnosis (mean delay - 1.8 ± 13.0 years), at an early stage, with only two relapses (no cancer-related death), while lung cancers were diagnosed late after. CONCLUSIONS: The tight chronological interplay between breast cancer and pSS and the intriguing pathological and immunological pattern of pSS in these patients suggest a hypothesis of immune control of cancer.

OBJECTIVES: This study aimed to estimate the prevalence of ANCA-associated vasculitis (AAV), ie granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA), in Southern France in 2018, and evaluate differences among Europeans and non-Europeans. METHODS: This population-based, cross-sectional study used four sources (hospitals, community-based physicians, laboratories, National Health Insurance) to identify adults ≥ 15 years diagnosed with GPA, MPA or EGPA, living in Hérault and Gard in 2018. Cases were defined using the ACR/EULAR classification criteria, and if necessary, the European Medicines Agency algorithm. Prevalence estimates were standardised to the world population and capture-recapture analysis was used to assess the comprehensiveness of the estimation. The influence of geographical origin was evaluated. RESULTS: 202 patients were selected, with 86 cases of GPA (42.6%), 85 cases of MPA (42.1%), and 31 cases of EGPA (15.3%). The standardised prevalence estimates per million inhabitants for 2018 were: 103 (95%CI 84 - 125) for AAV, 48 (95%CI 35 - 64) for GPA, 39 (95%CI 28 - 53) for MPA and 16 (95%CI 9 - 26) for EGPA, 36 (95%CI 25 - 50) for anti-PR3 positive AAV, 46 (95%CI 34 - 61) for anti-MPO positive AAV, and 16 (95%CI 9 - 26) for ANCA-negative AAV. The global estimation of comprehensiveness by capture-recapture analysis was 80.5%. The number of AAV cases was higher for non-European residents (P=0.001), particularly for MPA (P<0.0001). CONCLUSION: We provide a new estimate of AAV prevalence in France and show a higher prevalence of MPA in non-European patients.
RESUMEN
OBJECTIVES: Heart involvement is one of the leading causes of death in systemic sclerosis (SSc). The prevalence of SSc-related cardiac involvement is poorly known. Our objective was to investigate the prevalence and prognosis burden of different heart diseases in a nationwide cohort of patients with SSc. METHODS: We used data from a multicentric prospective study using the French SSc national database. Focusing on SSc-related cardiac involvement, we aimed to determine its incidence and risk factors. RESULTS: Over the 3528 patients with SSc 312 (10.9%) had SSc-related cardiac involvement at baseline. They tended to have a diffuse SSc subtype more frequently, more severe clinical features, and presented more cardiovascular risk factors. From the 1646 patients available for follow-up analysis, SSc-related cardiac involvement was associated with an increased risk of death. There was no significant difference in overall survival between SSc-related cardiac involvement, ischaemic heart disease or pulmonary arterial hypertension. Regarding survival analysis, 98 patients developed SSc-related cardiac involvement at five years (5-year event rate: 11.15%). Regarding reduced LVEF < 50% and left ventricular diastolic dysfunction, the 5-year event rate was 2.49% and 5.84% respectively. Pericarditis cumulative incidence at five years was 3%. Diffuse SSc subtype was a risk factor for SSc-related cardiac involvement and pericarditis. Female sex was associated with less left ventricular diastolic dysfunction incidence. CONCLUSIONS: Our results describe the incidence and prognostic burden of SSc-related cardiac involvement at a large scale, with gender and diffuse SSc subtype as risk factors. Further analyses should assess the potential impact of treatment on these various cardiac outcomes.
RESUMEN
OBJECTIVE: To describe the main features at diagnosis and evolution over time of patients with localized granulomatosis with polyangiitis (L-GPA) compared with those of systemic GPA (S-GPA). METHODS: EULAR definitions of L-GPA, i.e. upper and/or lower respiratory tract involvement, and S-GPA were applied to patients from the French Vasculitis Study Group Registry. L-GPA and S-GPA patients' characteristics at diagnosis and long-term outcomes were analysed and compared. RESULTS: Among the 795 Registry patients, 79 (10%) had L-GPA. Their main clinical manifestations were rhinitis, lung nodules, sinusitis and otitis. L-GPA vs S-GPA patients at diagnosis, respectively, were younger, more frequently had saddle nose deformity or subglottic stenosis and were less often PR3-ANCA-positive. L-GPA vs S-GPA induction therapy less frequently included CYC but more often a combination of MTX and glucocorticoids; 64% of MTX-treated patients experienced disease progression within 18 months post-diagnosis. L- and S-GPA patients' estimated relapse-free-survival probabilities, relapse rates and refractory disease rates at each time point were comparable, but L-GPA patients had more frequent ENT and lung relapses, and higher overall survival rates (P<0.02). Over a median follow-up of 3.5 years, 18 (22.8%) L-GPA progressed to S-GPA, either as a relapse after a period in remission or more frequently in the context of refractory disease. L-GPA patients experienced more ENT-related damage. CONCLUSIONS: The relapse risks of L-GPA and S-GPA were similar, but relapse patterns differed and L-GPA overall survival rate was higher. About one-quarter of L-GPA patients developed S-GPA over time, but without end-stage organ involvement.

OBJECTIVE: Adult-onset Still's disease (AOSD) is a rare inflammatory disease that may be life-threatening if complicated by cardiac problems. We performed a retrospective multicenter study to describe the manifestations, treatments and outcomes of cardiac involvement in AOSD. METHODS: We reviewed the medical databases of eight centers. All AOSD patients identified as fulfilling Yamagushi's or Fautrel's criteria were included in the study. Cardiac involvement, clinical manifestations, laboratory features, the course of the disease and treatments were evaluated. RESULTS: We included 96 AOSD patients in this study: 28 (29%) had documented cardiac involvement (AOSD + C group) and 68 (71%) had no cardiac involvement (control group). Cardiac complications were observed at diagnosis in 89% of cases. It were pericarditis (n = 17), tamponade (n = 5), myocarditis (n = 5) and non-infectious endocarditis (n = 1). Levels of leukocytes, neutrophils and C-reactive protein were significantly higher (p = 0.02, p = 0.02 and p = 0.002, respectively in the AOSD + C group than in the control group. Admission to intensive care, and the use of biotherapy were more frequent during follow-up in the AOSD + C group than the control group (p = 0.0001 and p = 0.03 respectively). Cardiac involvement was associated with refractory form in multivariate analyzed (p = 0.01). Corticosteroids were effective with or without methotrexate in 71% of patients but not in severe involvement as myocarditis or tamponade. CONCLUSION: Cardiac complications are frequent, inaugural, can be life-threatening and predictive of a refractory course in patients with AOSD. Systematic cardiac screening should be proposed at diagnosis and biotherapy early use should be considered especially in myocarditis.

OBJECTIVE: To describe characteristics and long-term outcomes of patients with microscopic polyangiitis (MPA), an antineutrophil cytoplasm antibody (ANCA)-associated small-vessel necrotizing vasculitis. METHODS: MPA patients from the French Vasculitis Study Group Registry satisfying the European Medicines Agency algorithm were analyzed retrospectively. Characteristics at diagnosis, treatments, relapses and deaths were analyzed to identify factors predictive of death or relapse. RESULTS: Between 1966 and 2017, 378 MPA patients (median age 63.7 years) were diagnosed and followed for a mean of 5.5 years. At diagnosis, the main clinical manifestations included renal involvement (74%), arthralgias (45%), skin (41%), lung (40%) and mononeuritis multiplex (32%), with less frequent alveolar hemorrhage (16%), cardiomyopathy (5%) and severe gastrointestinal signs (4%); mean serum creatinine was 217 µmol/L. ANCA were detected in 298/347 (86%) patients by immunofluorescence and/or enzyme-linked immunosorbent assay (ELISA). Among the 293 patients with available ELISA specificities, 272 (92.8%) recognized myeloperoxidase and 13 (4.4%) proteinase-3. During follow-up, 131 (34.7%) patients relapsed and 78 (20.6%) died, mainly from infections. Respective 5-year overall and relapse-free survival rates were 84.2% and 60.4%. Multivariable analyses retained age >65 years, creatinine >130 µmol/L, severe gastrointestinal involvement and mononeuritis multiplex as independent risk factors for death. Renal impairment was associated with a lower risk of relapse. CONCLUSION: Non-renal manifestations and several risk factors for death or relapse were frequent in this nationwide cohort. While mortality was low, and mainly due to treatment-related complications, relapses remained frequent, suggesting that MPA management can be further improved.

PURPOSE: Patients with primary immunodeficiency (PID) are at risk of serious complications. However, data on the incidence and causes of emergency hospital admissions are scarce. The primary objective of the present study was to describe emergency hospital admissions among patients with PID, with a view to identifying "at-risk" patient profiles. METHODS: We performed a prospective observational 12-month multicenter study in France via the CEREDIH network of regional PID reference centers from November 2010 to October 2011. All patients with PIDs requiring emergency hospital admission were included. RESULTS: A total of 200 admissions concerned 137 patients (73 adults and 64 children, 53% of whom had antibody deficiencies). Thirty admissions were reported for 16 hematopoietic stem cell transplantation recipients. When considering the 170 admissions of non-transplant patients, 149 (85%) were related to acute infections (respiratory tract infections and gastrointestinal tract infections in 72 (36%) and 34 (17%) of cases, respectively). Seventy-seven percent of the admissions occurred during winter or spring (December to May). The in-hospital mortality rate was 8.8% (12 patients); death was related to a severe infection in 11 cases (8%) and Epstein-Barr virus-induced lymphoma in 1 case. Patients with a central venous catheter (n = 19, 13.9%) were significantly more hospitalized for an infection (94.7%) than for a non-infectious reason (5.3%) (p = 0.04). CONCLUSION: Our data showed that the annual incidence of emergency hospital admission among patients with PID is 3.4%. The leading cause of emergency hospital admission was an acute infection, and having a central venous catheter was associated with a significantly greater risk of admission for an infectious episode.

Glomerulonephritis is a severe complication of microscopic polyangiitis (MPA), a small-vessel vasculitis associated with anti-myeloperoxidase antibodies (MPO-ANCA). We previously showed the pathogenic effects of MPO-ANCA that activate MPO to trigger an oxidative burst mainly through HOCl production, contributing to endothelial injury and lung fibrosis. The aim of this study was to investigate the relationship between MPO-induced oxidative stress, anti-oxidant defenses and renal histological lesions in MPA patients. We therefore analyzed histological data from a prospective cohort of ANCA-associated glomerulonephritis. Serum-mediated HOCl production, advanced oxidation protein products (AOPP), and thiol concentration in sera were determined. From 38 patients included, histological classification noted 50% focal glomerulonephritis, 15.8% crescentic-glomerulonephritis, and 34.2% mixed-glomerulonephritis. MPA patients' sera displayed higher HOCl production by MPO ( P < 0.001), higher AOPP ( P < 0.001) and thiol ( P < 0.01) levels, compared with healthy subjects. The presence of cellular crescents was associated with higher serum-mediated HOCl production ( P = 0.049) and lower thiol levels ( P = 0.022) at disease onset. Higher thiol concentrations were associated with focal glomerulonephritis ( P = 0.042), less interstitial fibrosis ( P = 0.039) and hyalinosis ( P = 0.066). In remission, HOCl production was decreased ( P < 0.01), and thiol concentration remained high ( P = 0.39). Our findings suggest that HOCl production by activated MPO could contribute to the very early stage of glomerulonephritis, whereas thiol may exert a protective effect against the development of renal vasculitis and glomerulosclerosis. This study highlights the importance of oxidative defenses to counteract the process of MPO-ANCA associated glomerulonephritis.

Adult onset Still's disease (AOSD) is a rare inflammatory disorder that remains poorly understood. Its pathophysiology is yet to be completely elucidated, but is known to consist mainly on a cytokine cascade, responsible for the systemic manifestations. AOSD diagnosis is usually difficult and delayed, with physicians having to rule out several other conditions, including cancer or infectious diseases. Prognosis is heterogeneous and difficult to establish, ranging from benign outcome to chronic destructive polyarthritis and/or life-threatening events. In addition, treatment remains to be codified, especially considering the development of new drugs. In this commentary, we attempt to elucidate the complexity of AOSD and to highlight the need of working on prognostic tools for this disorder. We also discuss the numerous advances that would be useful for patients in the daily management of this disease.Please see related article: http://bmcmedicine.biomedcentral.com/articles/ 10.1186/s12916-016-0738-8 .

OBJECTIVE.: Renal involvement is a rare event during primary SS (pSS). We aimed to describe the clinico-biological and histopathological characteristics of pSS-related nephropathy and its response to treatment. METHODS.: We conducted a French nationwide, retrospective, multicentre study including pSS patients fulfilling American-European Consensus Group criteria or enlarged American-European Consensus Group criteria, and with biopsy-proven renal involvement. RESULTS.: A total of 95 patients were included (median age 49 years). An estimated glomerular filtration rate (eGFR) of <60 ml/min was found in 82/95 patients (86.3%). Renal biopsy demonstrated tubulointerstitial nephritis (TIN) in 93 patients (97.9%), and frequent (75%) plasma cell infiltrates. Glomerular lesions were found in 22 patients (23.2%), mainly related to cryoglobulin. The presence of anti-SSA (76.8%) and anti-SSB (53.8%) antibodies was particularly frequent among patients with TIN and was associated with a worse renal prognosis. Eighty-one patients (85.3%) were treated, with CSs in 80 (98.8%) and immunosuppressive agents (mostly rituximab) in 21 cases (25.9%). Despite marked interstitial fibrosis at initial biopsy, kidney function improved significantly during the 12-month period following diagnosis (final eGFR 49.9 vs 39.8 ml/min/1.73 m 2 at baseline, P < 0.001). No proven benefit of immunosuppressive agents over steroid therapy alone was found in this study. CONCLUSION.: Renal involvement of pSS is mostly due to TIN with marked T, B and especially plasma cell infiltration. Renal dysfunction is usually isolated but can be severe. Use of CSs can improve the eGFR, but further studies are needed to define the best therapeutic strategy in this disease.

OBJECTIVES: Displaying immunosuppressive and trophic properties, mesenchymal stem/stromal cells (MSC) are being evaluated as promising therapeutic options in a variety of autoimmune and degenerative diseases. Although benefits may be expected in systemic sclerosis (SSc), a rare autoimmune disease with fibrosis-related mortality, MSC have yet to be evaluated in this specific condition. While autologous approaches could be inappropriate because of functional alterations in MSC from patients, the objective of the present study was to evaluate allogeneic and xenogeneic MSC in the HOCl-induced model of diffuse SSc. We also questioned the source of human MSC and compared bone marrow- (hBM-MSC) and adipose-derived MSC (hASC). METHODS: HOCl-challenged BALB/c mice received intravenous injection of BM-MSC from syngeneic BALB/c or allogeneic C57BL/6 mice, and xenogeneic hBM-MSC or hASC (3 donors each). Skin thickness was measured during the experiment. At euthanasia, histology, immunostaining, collagen determination and RT-qPCR were performed in skin and lungs. RESULTS: Xenogeneic hBM-MSC were as effective as allogeneic or syngeneic BM-MSC in decreasing skin thickness, expression of Col1, Col3, α-Sma transcripts, and collagen content in skin and lungs. This anti-fibrotic effect was not associated with MSC migration to injured skin or with long-term MSC survival. Interestingly, compared with hBM-MSC, hASC were significantly more efficient in reducing skin fibrosis, which was related to a stronger reduction of TNFα, IL1ß, and enhanced ratio of Mmp1/Timp1 in skin and lung tissues. CONCLUSIONS: Using primary cells isolated from 3 murine and 6 human individuals, this preclinical study demonstrated similar therapeutic effects using allogeneic or xenogeneic BM-MSC while ASC exerted potent anti-inflammatory and remodeling properties. This sets the proof-of-concept prompting to evaluate the therapeutic efficacy of allogeneic ASC in SSc patients.

OBJECTIVE: Coexistence of ANCA-associated vasculitis (AAV) and IBD is a rare condition that is rarely described in the literature. The aim of the study was to describe the main characteristics of patients presenting with both IBD and AAV. METHODS: A retrospective study of AAV patients in the French Vasculitis Study Group cohort who also had a diagnosis of IBD was conducted. We reviewed the medical records and outcomes of these patients. RESULTS: We identified 11 patients with AAV and IBD. Four patients with eosinophilic granulomatosis with polyangiitis (Churg-Strauss) also had ulcerative colitis and seven patients with granulomatosis with polyangiitis (GPA) had Crohn's disease. No Crohn's disease was observed in eosinophilic GPA and no ulcerative colitis in GPA. IBD started before AAV manifestations in six cases, simultaneously in two cases and after AAV manifestations in three cases. CONCLUSION: Coexistence of IBD and AAV is a rare condition. The therapeutic management of these patients includes corticosteroids in all cases and immunosuppressive drugs in some patients. Coexistence of IBD and AAV might be explained by common underlying inflammatory responses and cytokine profiles polarized towards either Th1 or Th2. Finally, in the presence of digestive manifestations in the context of AAV, the hypothesis of IBD should be assessed.

OBJECTIVE: The aim of this study was to describe the presentation and outcomes of patients with granulomatosis with polyangiitis (GPA) presenting with CNS involvement. METHODS: Patients were included in this nationwide retrospective study if they had GPA according to ACR criteria and/or the European Medicines Agency algorithm and CNS involvement. RESULTS: Thirty-five patients were included in the study. CNS involvement was observed in 51% of patients at GPA diagnosis. Headache (66%) was the main symptom, followed by sensory (43%) and motor impairment (31%). CNS involvement was characterized by pachymeningitis in 20, cerebral ischaemic lesions in 15 and haemorrhagic lesions in 2, with hypophyseal involvement in 2 patients. According to the clinical-radiological presentation, we distinguished granulomatous (G-CNS) and vasculitic (V-CNS) phenotypes. G-CNS patients more frequently had headaches, while V-CNS patients more frequently had motor impairment and renal involvement. Induction therapy produced clinical responses in 86% of patients. Baseline modified Rankin scale was higher for V-CNS than G-CNS patients (3 vs 2, P = 0.002). Initial spinal cord pachymeningitis was significantly associated with the need for a new induction regimen for relapsing/refractory disease (P = 0.01). Long-term neurological sequelae were noted in 51% of patients, including 35% with G-CNS and 69% with V-CNS (P = 0.08). Neurological sequelae were mainly noted in cases of spinal cord pachymeningitis (100%) and ischaemic or haemorrhagic lesions (73%). CONCLUSION: The clinical-radiological phenotype distinguished different long-term outcomes in patients with GPA and CNS involvement. Long-term neurological sequelae persisted in half of patients, mainly those with spinal cord pachymeningitis and vasculitic lesions.

OBJECTIVE: Earlier studies of eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA), with limited patient numbers and followup durations, demonstrated that clinical presentation at diagnosis, but not outcome, differed according to antineutrophil cytoplasmic antibody (ANCA) status. This study was undertaken to describe the main characteristics of a larger patient cohort and their long-term outcomes. METHODS: A retrospective study of EGPA patients in the French Vasculitis Study Group cohort who satisfied the American College of Rheumatology criteria and/or Chapel Hill definitions was conducted. Patient characteristics and outcomes were compared according to ANCA status and year of diagnosis. RESULTS: We identified 383 patients diagnosed between 1957 and June 2009 (128 [33.4%] before 1997 or earlier) and followed up for a mean±SD of 66.8±62.5 months. At diagnosis, their mean±SD age was 50.3±15.7 years, and 91.1% had asthma (duration 9.3±10.8 years). Main manifestations included peripheral neuropathy (51.4%); ear, nose, and throat (ENT) signs (48.0%); skin lesions (39.7%); lung infiltrates (38.6%); and cardiomyopathy (16.4%). Among the 348 patients tested at diagnosis for ANCA, the 108 ANCA-positive patients (31.0%) had significantly more frequent ENT manifestations, peripheral neuropathy, and/or renal involvement, but less frequent cardiac manifestations, than the ANCA-negative patients. Vasculitis relapses occurred in 35.2% of the ANCA-positive versus 22.5% of the ANCA-negative patients (P=0.01), and 5.6% versus 12.5%, respectively, died (P<0.05). The 5-year relapse-free survival rate was 58.1% (95% confidence interval [95% CI] 45.6-68.6) for ANCA-positive and 67.8% (95% CI 59.8-74.5) for ANCA-negative patients (P=0.35). Multivariable analysis identified cardiomyopathy, older age, and diagnosis during or prior to 1996 as independent risk factors for death and lower eosinophil count at diagnosis as predictive of relapse. CONCLUSION: The characteristics and long-term outcomes of EGPA patients differ according to their ANCA status. Although EGPA relapses remain frequent, mortality has declined, at least since 1996.

INTRODUCTION: Involvement of subcutaneous tissue in idiopathic inflammatory myopathies (IIM) is poorly known. METHODS: We conducted a systematic review of the literature regarding panniculitis and lipodystrophy/lipoatrophy in juvenile and adult IIM via PubMed/Medline, Embase and Scopus databases. Three local observations are included in this review. Epidemiological, clinical, paraclinical and therapeutic data were collected. RESULTS: Panniculitis appears to be more common in adults than in juveniles. It was mainly localised in the upper and lower limbs. Panniculitis improved in most cases with steroids and panniculitis and myositis had a similar course in 83.3% and 72.2% of cases in juveniles and adults, respectively. Lipodystrophy appeared to be more frequent in juveniles and was only observed in dermatomyositis in both juveniles and adults. Lipodystrophy was mainly partial in juveniles and adults. The median time from myositis to the diagnosis of lipodystrophy was 6 years [0-35] and 2.5 years [0-10] in juveniles and adults, respectively. Lipodystrophy was associated with anti-TIF1 gamma auto-antibody positivity, a polycyclic/chronic course of myositis and the occurrence of calcinosis and might be an indicator of poor disease control. CONCLUSION: Adipose tissue involvement, particularly lipodystrophy, occurs almost exclusively in dermatomyositis. The insidious onset and lack of awareness of the diagnosis may underestimate its prevalence. Larger studies are needed to identify possible risk factors in these patients, to better potential underlying pathophysiological process, in order to discuss potential therapeutic targets.

Primary Sjögren's syndrome (pSS) is an autoimmune disease with frequent neurological involvement. Memory complaints are common, but their precise patterns remain unclear. We wanted to characterize patterns of neurocognitive profiles in pSS patients with cognitive complaints. Only pSS patients with memory complaints were included, prospectively. Cognitive profiles were compiled through a comprehensive cognitive evaluation by neuropsychologists. Evaluations of anxiety, depression, fatigue, sleep disorders and quality of life were performed for testing their interactions with cognitive profiles. All 32 pSS patients showed at least borderline cognitive impairment, and 17 (53%) exhibited a pathological cognitive profile: a hippocampal profile (37%), a dysexecutive profile (22%), and an instrumental profile (16%) (possible overlap). Regarding the secondary objectives: 37% of patients were depressed, and 48% exhibited a mild-to-severe anxiety trait. Sleep disorders were frequent (excessive daytime sleepiness (55%), high risk for sleep apnea (45%), and insomnia (77%)). Cognitive impairments could not be explained alone by anxiety, depression or sleep disorders. Fatigue level was strongly associated with sleep disorders. Our study highlights that cognitive complaints in pSS patients are supported by measurable cognitive impairments, apart from frequently associated disorders such as depression, anxiety or sleep troubles. Sleep disorders should be screened.

OBJECTIVE: To investigate whether antineutrophil cytoplasm antibody (ANCA)-negative and myeloperoxidase (MPO)-ANCA-positive granulomatosis with polyangiitis (GPA) differ from proteinase-3 (PR3)-ANCA-positive GPA. METHODS: Diagnostic characteristics and outcomes of newly diagnosed French Vasculitis Study Group Registry patients with ANCA-negative, MPO-ANCA-positive or PR3-ANCA-positive GPA satisfying American College of Rheumatology criteria and/or Chapel Hill Conference Consensus Nomenclature were compared. RESULTS: Among 727 GPA, 62 (8.5%) were ANCA-negative, 119 (16.4%) MPO-ANCA-positive and 546 (75.1%) PR3-ANCA-positive. ANCA-negative patients had significantly (p<0.05) more limited disease (17.7% vs 5.8%) and less kidney involvement (35.5% vs 58.9%) than those PR3-ANCA-positive or MPO-ANCA-positive, with comparable relapse-free (RFS) and overall survival (OS). MPO-ANCA-positive versus PR3-ANCA-positive and ANCA-negative patients were significantly more often female (52.9% vs 42.1%), older (59.8 vs 51.9 years), with more frequent kidney involvement (65.5% vs 55.2%) and less arthralgias (34.5% vs 55.1%), purpura (8.4% vs 17.1%) or eye involvement (18.5% vs 28.4%); RFS was similar but OS was lower before age adjustment. PR3-positive patients' RFS was significantly lower than for ANCA-negative and MPO-positive groups combined, with OS higher before age adjustment. PR3-ANCA-positivity independently predicted relapse for all GPA forms combined but not when comparing only PR3-ANCA-positive versus MPO-ANCA-positive patients. CONCLUSIONS: Based on this large cohort, ANCA-negative versus ANCA-positive patients more frequently had limited disease but similar RFS and OS. MPO-ANCA-positive patients had similar RFS but lower OS due to their older age. PR3-ANCA-positive GPA patients' RFS was lower than those of the two other subsets combined but that difference did not persist when comparing only PR3 versus MPO-ANCA-positive patients.
