Background:The role of ANCA type is well established for the risk of relapses of ANCA-associated vasculitis (AAV). However their association with renal involvement and its outcomes is less well understood.Objectives:To assess clinical and morphological features of ANCA-associated glomerulonephritis (ANCA-GN) and renal survival in ANCA-negative patients, proteinase-3-ANCA (pr3-ANCA) positive and myeloperoxidase-ANCA (MPO-ANCA) positive patients.Methods:We enrolled 53 patients with AAV, diagnosed according to Chapel Hill Consensus Conference (2012) definition and/or ACR (1990) criteria, with histologically proven renal involvement. There were 13 (24.5%) males, median age at onset was 48 (33; 57) years. Seven patients were ANCA-negative (13.3%), 17 (32.0%) patients were pr-3-ANCA positive and 29 (54.7%) patients were MPO-ANCA-positive. ANCA-associates glomerulonephritis (ANCA-GN) class was established according to Berden et al classification.1We retrospectively assessed ANCA renal risk score (ARRS) at disease onset.2Twelve patients (22.6%) developed end-stage renal disease (ESRD) after a median of 12 (6.5; 28) months. Renal survival rates were assessed by Kaplan-Meier method and compared by log-rank test.Results:The only significant difference was median BVAS score which was significantly higher in pr3-ANCA-positive (18 (17;20)) than in MPO-ANCA positive patients (15 (12; 18), p=0.012). Creatinine levels, eGFR, percentage of glomeruli with crescents, global sclerosis, and interstitial fibrosis and tubular atrophy didn’t depend on the presence of ANCA or type of the antibodies. The proportion of patients with focal, crescentic, mixed of sclerotic class of ANCA-GN was similar in all groups. There was no significant difference in the numbers of patients with low, medium or high risk of ESRD according to ARRS. One- and three-year renal survival rates were similar in ANCA-negative (81.7% and 60.0% respectively) and ANCA-positive patients (84.2% and 74.6% respectively, Figure 1A). One-year and three-year survival rates were higher in MPO-ANCA-positive (84.4% and 84.4% respectively) than in pr3-ANCA-positive patients (73.1% and 50.1% respectively), however the difference was not statistically significant (Figure 1B).Figure 1.Kaplan-Meier curves showing renal survival in ANCA-positive and ANCA-negative patients (A), and pr3-ANCA-positive and MPO-ANCA-positive patients (B)Conclusion:Our small study indicates that clinical and morphological features of renal involvement, as well as renal survival are similar in ANCA-negative and ANCA-positive patients and don’t depend on the type of ANCA.References:[1]Berden AE, Ferrario F, Hagen EC, et al.

Abstract Background and Aims Despite significant progress in treatment of ANCA-associated vasculitis (AAV), at least 20% of patients with renal involvement develop end-stage renal disease (ESRD). Histopathologic classification by Berden et al, which addresses only glomerular pathology, has been used to predict renal outcome in ANCA-assoicted glomerulonephritis (ANCA-GN) since 2010.1 In 2018 Brix et al proposed ANCA renal risk score (ARRS), which combines assessment of morphological (percentage of normal glomeruli, tubular atrophy and interstitial fibrosis) and clinical parameters (estimated glomerular filtration rate) to predict probability of ESRD.2 The aim of our study was to compare clinical utility of these two methods. Methods In our retrospective study we enrolled 57 patients with ANCA-associated vasculitis, diagnosed according to Chapel Hill Consensus Conference (2012) definition and/or American College of Rheumatology (1990) criteria, with histologically proven renal involvement. There were 14 (24.6%) males and 43 (75.4%) females, median age at AAV onset was 48 (33; 57) years. Fifty-one (89.5%) patients were ANCA-positive. Eight (14.0%) patients were diagnosed with renal-limited AAV. Median Birmingham vasculitis activity score (BVAS v.3) at onset was 16 (13; 19). In each case ANCA-GN class was established according to Berden classification: focal (>50% normal glomeruli); crescentic (>50% cellular crescents); mixed (<50% normal, <50% crescentic, and <50% globally sclerotic glomeruli) or sclerotic (>50% globally sclerotic glomeruli). ARRS at onset was also retrospectively assessed and all patients were divided into three groups depending on the risk of ESRD: low risk (0 points), intermediate risk (2 to 7 points), or high risk (8 to 11 points). Thirteen patients (22.8%) developed ESRD after a median of 12 (6.5; 28) months. Renal survival rates were assessed by Kaplan-Meier method and compared by log-rank test. Results Among the 57 patients seven (12.3%) had focal, 10 (17.5%) – crescentic, 24 (43.2%) – mixed, and 16 (28.1%) – sclerotic ANCA-GN class according to Berden et al classification. 1- and 3-year renal survival rates were the highest (100% and 100% respectively) in focal, and the lowest in sclerotic class (67% and 50.2% respectively). 1- and 3- year renal survival was similar in crescentic (80% and 80% respectively) and mixed (80.6% and 80.6% respectively) classes (Fig. 1A). The differences were not statistically significant (Log-rank (Mantel-Cox) p = 0.17). Then we retrospectively re-evaluated all cases according to ARSS: 12 cases were classified as low-risk, 27 – as medium risk, 18 – as high risk. One-year and three-year survival rates were 100% and 100% in low-risk group, 86.1% and 74.2% in medium risk group, 50.6% and 50.6% in high risk group (Figure 1B). The differences were statistically significant (Log-rank (Mantel-Cox) p=0.003). Conclusion In our limited group of patients ANCA renal risk score classification provided better and more clear stratification of patients in terms of ESRD prediction than Berden classification. ARRS is a simple and valuable tool for assessment of renal survival prognosis which can contribute to personalized approach to the management of AAV.

Abstract Background and Aims Seasonal variation of ANCA associated vasculitis (AAV) and a possible link to extrinsic infective triggers is predominantly based on single centre epidemiological data. Despite frequent confounding factors including difficulty in identifying the precise time of disease onset, seasonality may be associated with the type of vasculitis and may impact the incidence of renal involvement. Therefore, the aim of this study was to explore if there is an association between seasonality, severity and incidence of biopsy-proven renal vasculitis in the Scottish population. Method Using the Scottish renal biopsy registry, we identified all adult native renal biopsies performed across Scotland between 2014 and 2018 with a diagnosis of AAV, including microscopic polyangiitis (MPA) and granulomatosis with polyangitis (GPA). Demographic data including ANCA antibody status, histological diagnosis, estimated glomerular filtration rate (eGFR) and proteinuria at presentation were recorded. Seasons were defined as autumn (September – November), winter (December-February), spring (March – May) and summer (June - August). Statistical analysis was performed using multivariate ANOVA analysis and Student’s t-test in parametric data. Results 339 cases of biopsy proven AAV were identified and included in the analysis. In this cohort, 53% were female with mean patient age of 65.6 years (± 13). Mean estimated glomerular filtration rate (eGFR) at the time of diagnosis of AAV was 32 (± 27.2) mL/min/1.73m2 and median urinary protein creatinine ratio (uPCR) was 146mg/mmol (IQR 79.8 – 271.3). Diagnosis of MPA n=209(62%) was more common than GPA n=130(38%) and patients with MPA were significantly younger at presentation (63.5 ± 13.6 ‘vs’ 67 ± 12.7 years, p = 0.017). Otherwise, these groups did not differ in mean eGFR (MPA 29.6 ± 25.7 ‘vs’ GPA 34.8 ± 27.6 mL/min/1.73m2) or median uPCR (MPA 147, IQR 78.6 – 286.5 ‘vs’ GPA 139, IQR 80.5 – 261 mg/mmol) at onset. We observed a mean of 3.5 (± 1) new cases of MPA and 2.1 (± 0.7) new cases of GPA per month, with no significant difference observed in month-to-month comparison. Seasonal analysis showed mean occurrence of 11.4 (± 4.5) cases of MPA in autumn, 11.2 (± 4.9) in winter, 10.6 (± 1.5) in spring and 8.6 (± 1.9) in summer months. In GPA, mean 6.6 (±2.7) cases occurred each autumn, 5.4 (± 3) in winter, 7.2 (± 2.9) in spring and 6.4 (± 0.9) in summer months. Overall, no significant differences in monthly or seasonal incidence across 5 years of monitoring were detected. Similarly, we observed no difference in renal function at presentation during different seasons for MPA (mean eGFR range 21.8 – 37.6 mL/min/1.73m2, uPCR median range 112 – 167.5 mg/mmol) or GPA (mean eGFR range 32-37 mL/min/1.73m2; uPCR median range 110 – 244 mg/mmol). Conclusion Our data suggest that there is no seasonal variation in the incidence of AAV diagnosed on kidney biopsy in patients living in Scotland. Additionally, patients present with similar levels of kidney function regardless of season. Thus traditional holiday periods i.e. Easter/Christmas do not seem to lead to a delay in diagnosis. This is the first study to consider seasonality in a complete national cohort and suggests that seasonal extrinsic factors do not play a major role in the pathogenesis leading to AAV onset.

Background:Tofacitinib (TOFA) is an oral, small molecule drug used for rheumatoid arthritis (RA) treatment and is prescribed alone or with methotrexate (MTX). Tofa can be used as an alternative to biologic disease modifying antirheumatic drugs (bDMARDs) including tumor necrosis factor inhibitors (TNFi).Objectives:We aimed to evaluate the discontinuation rate of this drug, with and without concurrent MTX in comparison with TNFi, in patients with RA in the Ontario Best Practices Research Initiative (OBRI).Methods:RA patients enrolled in the OBRI initiating their TOFA or TNFi (adalimumab, certolizumab, etancercept, golimumab, and infliximab) within 30 days prior to or any time after enrolment between 1stJune 2014 (TOFA approval date in Canada) and 31stDec 2018 were included. Time to discontinuation (due to any reason) were assessed using Kaplan-Meier survival (adjusted for propensity score using inverse probability of treatment weight) to compare patients with and without MTX use at initiation of TOFA or TNFi.Results:A total of 565 patients initiated TOFA (n=208) or TNFi (n=357). Of those, 106 (51%) and 222 (62%) were treated with MTX in the TOFA and TNFi group, respectively and mean (SD) disease duration were 13.1 (9.4) and 9.5 (9.4) years. In the TOFA group, 86% were female and mean (SD) age at treatment initation was 60.4 (10.6) years. In the TNFi group 82% were female and mean age (SD) at treatment initation was 57.0 (12.6) years. The TOFA group was more likely to have prior biologic use (61.5%) compared with the TNFi group (31%). At treatment initiation, the mean (SD) clinical disease activcity index was 24.8 (12.1) in the TOFA group and 21.8 (12.0) in the TNFi group.Over a mean of 17.3 month follow-up, discontinuation was reported in 75 (36%) and 103 (29%) of all TOFA and TNFi patients, respectively. After adjusting for propensity score, patients treated with TNFi and MTX remained on treatment longer than those treated without MTX (Logrank p=0.002) while there was no significant difference in TOFA discontinuation in patients with and without MTX (Logrank p=0.31).Conclusion:In this real world data study, we found that TOFA retention is similar in patients with and without MTX, while patients treated with TNFi and MTX remained on treatment longer than those treated without MTX. Merging data with other RA registries in Canada is proposed to increase study power and to provide more robust results.Disclosure of Interests:Mohammad Movahedi Consultant of: Allergan, Angela Cesta: None declared, Xiuying Li: None declared, Edward Keystone Grant/research support from: AbbVie; Amgen; Gilead Sciences, Inc; Lilly Pharmaceuticals; Merck; Pfizer Pharmaceuticals; PuraPharm; Sanofi, Consultant of: AbbVie; Amgen; AstraZeneca Pharma; Bristol-Myers Squibb Company; Celltrion; F.

Background:Several biologic DMARDs (bDMARDs) exist for PsA, TNFi and UST being the earliest on European markets. When bDMARDs are insufficiently effective, later-line bDMARDs typically have shorter persistence. Treatment persistence reflects a mix of effectiveness and adverse events (AEs), and persistence data are limited in PsA.Objectives:Comparative analysis of 1-year persistence of UST and TNFi within the prospective PsABio cohort.Methods:PsABio is an observational, multinational study of PsA patients (pts) treated with 1st to 3rd line UST or TNFi at their rheumatologist’s discretion.1Treatment persistence (up to 15 months of follow-up) was defined as time between start of first bDMARD treatment in PsABio, and either stop or switch to another bDMARD, or withdrawal.Persistence of UST and TNFi is shown by Kaplan-Meier curves and compared using Cox regression analysis, with propensity score (PS) to adjust for baseline imbalanced demographic and disease-related covariates (age, sex, bDMARD line, BMI, Clinical Disease Activity index for PSoriatic Arthritis [cDAPSA], 12-item PsA Impact of Disease [PsAID-12], Fibromyalgia Rapid Screening Tool [FiRST] score, co-treatments with MTX, NSAIDs, glucocorticoids, cardiovascular/metabolic comorbidities, dactylitis, enthesitis and body surface area [BSA]). Factors including concomitant MTX use and skin involvement: <3%, 3–10% and >10%, were added to the Cox model to investigate their impact on the PS-adjusted treatment effect.Results:Of 438 and 455 pts who started UST and TNF, respectively, 121 (28%) and 134 (29%) stopped or switched treatment before Month 15, with differences (as expected) according to treatment line (Fig. 1a, b). Reasons for stop/switch were related to safety/AEs in 12% (UST) and 28% (TNFi), and effectiveness (joints, nails or skin) in 77% (UST) and 69% (TNFi) of pts.The observed mean time on drug was 397 days for UST and 385 days for TNFi pts (1st line 410/397 days, 2nd 390/382 days, 3rd 381/338 days). Fig. 1b shows similar persistence for all drugs and treatment lines, except for lower persistence in TNFi 3rd line vs 1st/2nd. In PS-adjusted Cox analysis, no statistically significant difference between UST and TNFi persistence was seen; hazard ratio (HR; 95% CI) for stop/switch bDMARD (UST vs TNFi) was 0.82 (0.60, 1.13). In the model, bDMARD monotherapy (without MTX) and extensive skin involvement (BSA >10%), showed significantly better persistence for UST (HR 0.61 [0.42, 0.90] and 0.41 [0.19, 0.89] respectively; unadjusted Kaplan-Meier graphs shown in Fig. 1c, d). MTX co-therapy and low BSA did not affect the PS-adjusted treatment effect. Other factors added to the PS-adjusted Cox model did not show significant effects.Conclusion:In this real-world PsA cohort undergoing bDMARD treatment, persistence was generally comparable for UST and TNFi, but some clinical situations led to better drug persistence with UST compared to TNFi – particularly monotherapy, more extensive skin involvement, and in 3rd-line treatment. Our data emphasise the importance of skin involvement for pts with PsA.References:[1]Gossec L, et al.Ann Rheum Dis. 2018;77(suppl 2):Abstract AB0928Acknowledgments:This study was funded by Janssen.Disclosure of Interests:Laure Gossec Grant/research support from: Lilly, Mylan, Pfizer, Sandoz, Consultant of: AbbVie, Amgen, Biogen, Celgene, Janssen, Lilly, Novartis, Pfizer, Sandoz, Sanofi-Aventis, UCB, Stefan Siebert Grant/research support from: BMS, Boehringer Ingelheim, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, UCB, Consultant of: AbbVie, Boehringer Ingelheim, Janssen, Novartis, Pfizer, UCB, Speakers bureau: AbbVie, Celgene, Janssen, Novartis, Paul Bergmans Shareholder of: Johnson & Johnson, Employee of: Janssen, Kurt de Vlam Consultant of: Celgene Corporation, Eli Lilly, Novartis, Pfizer, UCB – consultant, Speakers bureau: Celgene Corporation, Eli Lilly, Novartis, Pfizer, UCB – speakers bureau and honoraria, Elisa Gremese Consultant of: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer, Speakers bureau: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer, Beatriz Joven-Ibáñez Speakers bureau: Abbvie, Celgene, Janssen, Merck Sharp & Dohme, Novartis, Pfizer, Tatiana Korotaeva Grant/research support from: Pfizer, Consultant of: Abbvie, BIOCAD, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Novartis-Sandoz, Pfizer, UCB, Speakers bureau: Abbvie, BIOCAD, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Novartis-Sandoz, Pfizer, UCB, Wim Noel Employee of: Janssen Pharmaceuticals NV, Michael T Nurmohamed Grant/research support from: Abbvie, Bristol-Myers Squibb, Celltrion, GlaxoSmithKline, Jansen, Eli Lilly, Menarini, Merck Sharp & Dohme, Mundipharma, Pfizer, Roche, Sanofi, USB, Consultant of: Abbvie, Bristol-Myers Squibb, Celltrion, GlaxoSmithKline, Jansen, Eli Lilly, Menarini, Merck Sharp & Dohme, Mundipharma, Pfizer, Roche, Sanofi, USB, Speakers bureau: Abbvie, Bristol-Myers Squibb, Celltrion, GlaxoSmithKline, Jansen, Eli Lilly, Menarini, Merck Sharp & Dohme, Mundipharma, Pfizer, Roche, Sanofi, USB, Petros Sfikakis Grant/research support from: Grant/research support from Abvie, Novartis, MSD, Actelion, Amgen, Pfizer, Janssen Pharmaceutical, UCB, Elke Theander Employee of: Janssen-Cilag Sweden AB, Josef S.

Abstract Background : To investigate whether there is a distinct difference in prognosis between hepatoid adenocarcinoma of the stomach ( HAS) and non-hepatoid adenocarcinoma of the stomach (non-HAS) and whether HAS can benefit from radical surgery. Methods : We retrospectively reviewed 722 patients with non-HAS and 75 patients with HAS who underwent radical gastrectomy between 3 November 2009 and 17 December 2018. Propensity score matching (PSM) analysis was used to eliminate the bias among the patients in our study. The relationships between gastric cancer type and overall survival (OS) were evaluated by the Kaplan-Meier method and Cox regression. Results : Our data demonstrate that there was no statistically significant difference in the OS between HAS and non-HAS {K-M, P=log rank (Mantel-Cox), (before PSM P=0.397); (1:1 PSM P=0.345); (1:2 PSM P=0.195)}. Moreover, there were no significant differences in the 1-, 2-, or 3-year survival rates between patients with non-HAS and patients with HAS (before propensity matching, after 1:1 propensity matching, and after 1:2 propensity matching). Conclusion : HAS was generally considered to be an aggressive gastric neoplasm, but its prognosis may not be as unsatisfactory as previously believed.

Aim. This study aimed to retrospectively compare the survival outcomes over two years between teeth with proximal dental caries that were restored with stainless-steel crowns to those that were pulpotomized and then restored with a stainless-steel crown in patients who were rehabilitated under general anesthesia. Participants and Methods. The records of 131 patients aged between two to six years who had stainless-steel crowns placed under general anesthesia and had two-year follow-up were screened. 340 teeth with moderate proximal caries on the radiograph (D2) were included in the study. Of these, 164 teeth were treated with a pulpotomy and stainless-steel crown, while 176 teeth were crowned without a pulpotomy. The type of each tooth was compared using the Chi-squared test and Kaplan–Meier survival analysis, and curves were plotted based on the two-year outcomes. Results. Treatment: the sample comprised 59 males (mean age 4.73 years, SD ± 1.4 years) and 72 females (mean age 5.2 years, SD ± 2.0 years). The Kaplan–Meier regression model showed no significant difference in survival outcomes between teeth that had been pulpotomized and those that had not ( p  = 0.283). Conclusion. Within the limitations of the current study, we can conclude that performing a pulpotomy does not influence the survival outcome of mild/moderate proximal caries restored with stainless-steel crowns under general anesthesia.

185 Background: Obesity is one of the factors commonly associated with pancreatic cancer risk, but its prognostic role for survival is debatable. This study aimed to determine the role of BMI in treatment outcomes of pancreatic cancer patients (pts) undergoing surgical resection followed by adjuvant therapy. Methods: We retrospectively reviewed 165 consecutive pts with pancreatic cancer undergoing pancreaticoduodenectomy at Indiana University Hospital between 2004 and 2008. Fifty-three pts who received adjuvant treatment [gemcitabine alone (C-group): n=19; gemcitabine + radiotherapy (CRT-group): n=34] at our institution were included in the analysis. The Kaplan-Meier method was used to estimate the disease-free survival (DFS) and overall survival (OS); log-rank test was used to compare these outcomes between BMI groups (normal 18.5-24.99 kg/m2 vs. overweight/obese ≥ 25 kg/m2). Results: The sample comprised 53 pts (28 males; median age 62 yrs) with a median follow-up of 18.6 months (mos). Thirty pts (56.6%) had their BMIs recorded before the date of surgery, and 23 pts prior to starting adjuvant therapy. Two (3.8%) pts were underweight, 21 (39.6%) had a normal BMI and 30 (56.6%) were overweight/obese. There was no statistically significant difference in the median DFS of obese/overweight and normal BMI pts irrespective of adjuvant therapy (C or CRT) (14.47 vs. 11.80 mos; p= 0.111). Obese/overweight pts had a better median OS [25.2 vs. 14.6 mos; p=0.045 overall (25.7 vs. 16.9 mos; p= 0.143 for the CRT-group and 17.3 vs. 13.4 mos; p= 0.050 for the C-group)], 1-year survival [96.7% vs. 61.9%; p < 0.0001 overall (95% vs. 64.3%; p= 0.001 for the CRT-group, and 90% vs. 57.1%; p=0.016 with C)], and 2-year survival [52.6% vs. 25.4%; p < 0.0001 overall (60.0% vs. 30.0%; p=0.0001 for the CRT-group and 37.5% vs. 14.3%; p=0.0002 for the C-group)] than patients with normal BMI. Conclusions: In our experience, overweight/obese pts undergoing surgery followed by adjuvant therapy have better survival rates than patients with normal BMI.

The purpose of this retrospective study was to evaluate the survival rate by comparing Class II restoration using flowable resin composite with stainless steel crown in primary molars.Electronic medical records and radiographs of 1,504 primary molars with proximal caries of 590 patients from June 2015 to August 2019 were analyzed. With the collected data, survival analysis was performed using the Kaplan-Meier method.The 1-year survival rate of flowable resin composite in the primary molar was 98.5%, 3-year survival rate was 87.7%, and mean survival time was 39 months. There was no statistically significant difference between flowable resin composite and stainless steel crown (<i>p</i> = 0.896).Within the limits of this study, Class II restoration using flowable resin composite can be considered a promising option for the treatment of proximal caries in primary molars.

The Matrix

Background:There is a paucity of information on the current phenotypes, ethnic and geographic differences of PAN. A global PAN study group has been working for clinical subphenotype and GWAS studies.Objectives:This study is aimed to look for target organ associations in PAN.Methods:PAN patients fulfilling the EMA vasculitis classification algorithm were recruited. In addition to baseline characteristics, treatment and outcome data, occurrence of any of the clinical manifestations related to PAN during disease course was recorded.Factor analysis was used to analyse target organ associations of 306 patients. Five factors were identified by factor analysis of variables sex, paediatric-onset, HBV, monogenic disease relationship, cutaneous features, musculoskeletal symptoms, constitutional symptoms and involved areas (abdominal, renal, neurologic, ENT, cardiac, pulmonary).Results:PAN cohort from 7 countries were used (Italy: n=59, Japan: n=39, Mexico: n=29, Slovenia: n=14, Sweden:11, TUR: n=106, UK: n=48). 306 (M/F: 171/135 and Caucasian 77.1%, Asian 13.4%, and Hispanic 9.5%) patients were included. 8 were HBV-related, and 22 of TUR patients had a monogenic form of disease (FMF n=15, DADA2 n=7). 21.8% of patients were cutaneous-only PAN patients. 48.4% of patients had radiologic, 64% had biopsy-proven PAN. Median age at disease onset was 40 (IQR 27.0-57.5) years. During a median 57 (16-120) months follow-up, 39 (13%) patients died.Factor analysis revealed 5 factors that explained 54.1% of the original information on the matrix as follows:Factor 1,represented the association between gastrointestinal and renal involvement, male gender and negatively associated with cutaneous features;Factor 2,the association between monogenic relationship with paediatric onset disease;Factor 3,any of musculoskeletal findings with positive constitutional symptoms;Factor 4any neurologic involvement was associated with ENT and pulmonary findings;Factor 5cardiac involvement in non-HBV patients (Table).The eigenvalues of the 5 factors were 2.034, 1.470, 1.427, 1.079 and 1.030, in decreasing order, i.e., the highest contribution to the overall variance in the matrix came from the togetherness of the 4 clinical and demographic characteristics that made up Factor 1.Conclusion:Target organ associations could support distinctive subphenotypes in PAN. Factor 1 seems the most severe form. Patients with FMF or DADA2 have distinct target organ associations. The jury is out to decide whether these patients should be classified as ‘vasculitis associated with probable etiology’ just as HBV-related-PAN. Factor 4 might define a different subphenotype (ANCA- medium vessel vasculitis?).Disclosure of Interests:Omer Karadag: None declared, Ertugrul Cagri Bolek: None declared, Shunsuke Furuta: None declared, Giacomo Emmi: None declared, ALOJZIJA HOCEVAR: None declared, Andrea Hinojosa-Azaola: None declared, Aladdin J Mohammad Speakers bureau: lecture fees from Roche and Elli Lilly Sweden, PI (GiACTA study), Serdal Ugurlu: None declared, Fatma Alibaz-Oner: None declared, Ayten Yazici: None declared, Luca Quartuccio: None declared, Enrica Bozzolo: None declared, Lorenzo Dagna Grant/research support from: Abbvie, BMS, Celgene, Janssen, MSD, Mundipharma Pharmaceuticals, Novartis, Pfizer, Roche, SG, SOBI, Consultant of: Abbvie, Amgen, Biogen, BMS, Celltrion, Novartis, Pfizer, Roche, SG, and SOBI, Giuseppe Alvise Ramirez: None declared, Luca Cantarini: None declared, Gina Gregorini: None declared, Jeannin Guido: None declared, Sara Monti: None declared, Eduardo Martin-Nares: None declared, Franco Schiavon: None declared, Roberto Padoan: None declared, Hajime Kono: None declared, Augusto Vaglio: None declared, Saadettin Kiliçkap: None declared, Ali İhsan Ertenli: None declared, Haner Direskeneli: None declared, Seza Özen Consultant of: Novartis, Pfizer, Speakers bureau: SOBI, Novartis, David Jayne Grant/research support from: ChemoCentryx, GSK, Roche/Genentech, Sanofi-Genzyme, Consultant of: Astra-Zeneca, ChemoCentryx, GSK, InflaRx, Takeda, Insmed, Chugai, Boehringer-Ingelheim

Background Renal involvement in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is associated with poor outcomes. The clinical significance of arteritis of the small kidney arteries has not been evaluated in detail. Methods In a multicenter cohort of AAV patients with renal involvement, we sought to describe the clinicopathologic characteristics of patients with AAV who had renal arteritis at diagnosis and to retrospectively analyze their prognostic value. Results We included 251 patients diagnosed with AAV and renal involvement between 2000 and 2019, including 34 patients (13.5%) with arteritis. Patients with AAV-associated arteritis were older and had a more pronounced inflammatory syndrome compared with patients without arteritis; they also had significantly lower renal survival (P=0.01). In multivariable analysis, the ANCA renal risk score, age at diagnosis, prior history of diabetes mellitus, and arteritis on index kidney biopsy were independently associated with end-stage renal disease. The addition of the arteritis status significantly improved the discrimination of the ANCA renal risk score, with a concordance index (C-index) of 0.77 for the ANCA renal risk score alone versus a C-index of 0.80 for the ANCA renal risk score plus arteritis status (P=0.008); ESRD-free survival was significantly worse for patients with an arteritis involving small arteries who were classified as having low or moderate risk according to the ANCA renal risk score. In two external validation cohorts, we confirmed the incidence and phenotype of this AAV subtype. Conclusions Our findings suggest that AAV with renal arteritis represents a different subtype of AAV with specific clinical and histologic characteristics. The prognostic contribution of the arteritis status remains to be prospectively confirmed.
