Objectives Herein, we investigate the presence and prognostic value of autoantibodies against carbamylated proteins (anti-CarP) in the serum of patients with primary Sjögrens syndrome (pSS). Patients and methods Serum levels of anti-CarP antibodies were measured in Norwegian patients with pSS (n=78) and corresponding controls (n=74) using ELISA and analysed in relation with exocrine gland function, degree of salivary gland inflammation, signs of ectopic germinal centre (GC) formation and immunological markers. For univariate comparisons, the Mann–Whitney U test and χ2 or Fishers exact tests were used. Correlations were assessed with Spearmans rank testing. Multivariate regression analyses were used to assess the effect of anti-CarP positivity on clinical manifestations. Results Of the patients with pSS, 27% were positive for anti-CarP IgG antibodies. Levels of anti-CarP correlated positively with total IgG, IgM, rheumatoid factor and β2-microglobulin. Importantly, after adjusting for confounding factors, patients positive for anti-CarP had significantly higher focus score. Furthermore, positive anti-CarP status coincided with 9.2-fold higher odds of having developed GC-like structures in the minor salivary glands. As a patient group considered having worse disease outcome, individuals with ectopic GC-like structures also presented with significantly higher levels of anti-CarP antibodies. Conclusions Presence of anti-CarP in patients with pSS is strongly associated with increased focal lymphocytic infiltration, formation of ectopic GC-like structures in minor salivary glands, and diminished salivary gland function. Even taking into consideration our relatively small cohort we believe that anti-CarP antibodies offer new possibilities for identifying patients with more active disease and at risk of developing additional comorbidity.

Abstract Autoimmune polyendocrine syndrome type I (APS-I) is a severe disease caused by mutations in the autoimmune regulator (AIRE) gene. We hypothesized that salivary gland dysfunction could be a possible unexplored component of these patients and here aimed to investigate salivary and lachrymal symptoms in the Norwegian cohort of APS-I patients (N = 41) and the aetiology behind it. Sicca symptoms and possible corresponding underlying factors were assessed by subjective reports combined with objective measures of saliva and tear flow, serological testing, immune fluorescence microscopy, ultrasonography and searching for putative autoantibodies in the salivary glands. In addition, defensin and anti-defensin levels were analysed in patients and compared with healthy controls. Our results indicate mild salivary and/or lachrymal gland dysfunction manifesting in low saliva or tear flow in a total of 62% of APS-I patients. Serum IgG from 9 of 12 patients bound to targets in salivary gland biopsy slides, although the specificity and pattern of binding varied. There was no reactivity against known Sjögren-associated autoantigens in sera from APS-I patients using quantitative methods, but 11% were ANA positive by immunofluorescence microscopy. We identified several putative autoantigens in one patient, although none of these were verified as APS-I specific. We conclude that impaired salivary gland activity is part of the clinical picture of APS-I and our findings could indicate an autoimmune aetiology. We further show that APS-I patients have an altered antimicrobial signature in both sera and saliva, which requires further investigations.

Objectives To analyse the diagnostic approach used in the largest international cohort of patients with primary Sjögren syndrome (pSS) Methods The Big Data Sjögren Project is a multicentre registry formed in 2014 by experts participating in the EULAR-SS Task Force. By January 2016, the database included 8315 consecutive patients fulfilling the 2002 criteria. The main features at diagnosis/recruitment (time of criteria fulfilment) were collected and analysed Results The cohort included 7753 (93%) women (mean age at diagnosis 53 years). Sicca symptoms were reported in more than 90% of patients at diagnosis (92% for dry eye and 92.5% for dry mouth). The diagnostic tests used included the determination of anti-Ro/La antibodies in 8250 (99%) patients, Schirmer test in 6205 (75%), salivary gland biopsy in 5988 (72%), salivary flows in 4941 (59%), corneal stainings in 3304 (40%), scintigraphy in 2578 (31%) and sialography in 873 (10%) patients. The mean number of diagnostic tests included in the 2002 AE criteria was 4.85 ± 1.44 (of a maximum of 8 different tests), and was higher in patients with negative ANA (5.18 vs 4.80 in ANA+, p<0.001) or negative RF (5.06 vs 4.81 in RF+, p<0.001), and was also higher in American patients vs European or Asian patients (5.28 vs 4.83 and 4.63, respectively). A correlation was found between the number of tests carried out and the number of 2002 criteria finally fulfilled (R=0.48) Conclusions We found a heterogeneous diagnostic approach of pSS with respect to the number of 2002AE diagnostic tests carried out; the approach varied significantly according to geographic origin and baseline immunological profile Disclosure of Interest None declared

Are Ankylosing Spondylitis, Psoriatic Arthritis and Undifferentiated Spondylarthritis Associated with an Increased Risk of Cardiovascular Disease?For a searchable version of these abstracts, please visit www.acrabstracts.org. Please Note: It may take several minutes for this file to download.Background/Purpose: Person-centred care (PCC) is a holistic approach with respectful and individualized care allowing negotiation of care where persons with health problems are empowered to be involved in health decisions. Patients’ illness narratives constitute a starting point for building a collaboration with health care professionals and to empower them to play an active role in their health care. Little is known of the impact of PCC vs. regular care on patients’ skills as health care consumers. The aim was to study the impact on effective consumers’ skills over 6 and 12 months as measured by the Effective Consumer Scale (EC17) in patients undergoing biological therapy and randomly assigned to either a nurse-led rheumatology clinic (NLC) based on PCC or to a rheumatologist-led clinic (RLC) based on regular care.Methods: A 12 month RCT in 107 patients with chronic inflammatory arthritis1. Inclusion criteria were ongoing biological therapy and a DAS28 ≤3.2. All patients met a rheumatologist at inclusion and after 12 months, while the 6 month follow-up was randomized to either at an NLC (PCC) or at an RLC (regular care). Outcome measure was the EC17, developed and endorsed by the OMERACT, including five subscales; 1. Use of health information, 2. Clarifying personal priorities, 3. Communicating with others, 4. Negotiating roles and 5. Deciding and taking action. EC17 total score ranges from 0-100, worse to best. Differences between and within NLC and RLC were analyzed with Friedmans’ test or Mann Whitney U-test.Results: After 12 months 97 patients completed the RCT (NLC n=47, RLC n=50), mean (SD) age 55.4 (12.7) years, disease duration 16.7 (11.5) years, DAS28 2.1 (0.7), HAQ 0.54 (0.38), global health 20.4 (17.1), pain 21.1 (18.0) and 56% were women. There were no statistically significant differences within or between the two intervention groups at baseline nor in EC17 total score mean (SD) at baseline (NLC 83.5 (9.4) vs. RLC 83.2 (10.8), 6 months (NLC 85.4 (10.4) vs. RLC 82.9 (10.9) and 12 months (NLC 85.3 (11.1) vs. RLC 82.3 (10.9)). However, in NLC there was a statistically significant improvement in EC17 subscale “1. Use of health information” at both 6 and 12 months (p=0.041 and p=0.004 respectively).Conclusion: Replacing just one of three visits over 12 months to an NLC based on PCC instead of an RLC based on regular care resulted in more effective consumers concerning the use of health information. Larger studies over longer time frames focusing on PCC are needed to better understand its full impact on effective consumer skills measured by EC17.References:1. Larsson I, et al. Randomized controlled trial of a nurse-led rheumatology clinic for monitoring biological therapy. J Adv Nurs 2014;70:164-75.Background/Purpose: Chronic widespread pain (CWP), one of the hallmarks of fibromyalgia, is not uncommon in adolescents and it has previously been shown that adolescents with pain often become young adults with pain. CWP often co-varies with anxiety, depression, and stress symptoms in adults, but the knowledge regarding this is small in youth and young adults.The aim was to study the associations between CWP, anxiety, depression and stress in adolescents attending first year of high school.Methods: A computerized questionnaire to 296 adolescents attending Swedish high school, with validated questions regarding presence and distribution of pain (Epipain mannequin), stress symptoms (ELO question), anxiety and depression (Hospital Anxiety and Depression Scale – HADS), and health related quality of life (HRQL as measured by EQ5D). Pain was considered chronic when persistent for more than three months, and the subgroup CWP was defined according to the 1990 ACR criteria for fibromyalgia. Statistical analyses in SPSS v21 with comparison of means by Student’s t-test and proportions by chi2-test or Fischer’s exact test.Results: 257 (87%) out of 296 eligible students, mean (SD) age 16.1 (0.7) and 65.8% girls, responded to the questionnaire. Prevalence of chronic pain was 20.8% and that of the subgroup CWP was 4.7%, without any gender differences (boys 18.2% vs girls 22.2%; p=0.224, and 3.4% vs 5.4%; p=0.692). High level (4 or 5 on a 5 point scale) of stress symptoms were less common in boys (16.0% vs 28.2%; p=0.015), as was possible or probable anxiety (17.1% vs 44.4%; p<0.001), but not depression (10.3% vs 12.5%; p=0.764). Students with high level of stress reported CWP five times more often than those with less stress (30.4% vs 5.8%; p=0.001). Students with probable anxiety reported CWP ten times more often than students with no anxiety (17.6% vs 1.8%; p=0.001), and CWP was also more common, but not statistically significant, in students with probable depression (20.0% vs 3.1%; p=0.163). Those reporting CWP had significantly lower HRQL (0.58 vs 0.87; p=0.038) than students with no chronic pain.Conclusion: The high prevalence of chronic pain and the strong associations between CWP and reports of stress and anxiety in adolescents highlights that a multifactorial background to chronic pain must be considered early in life. An apparent lower score in EQ5D also indicates that the presence of CWP has an marked impact on HRQL also in adolescents.Background/Purpose: The treatment target for axial spondyloarthritis (SpA) is to maximize health-related quality of life (HRQoL) by controlling disease activity and improving functioning. The treatment cornerstones are a combination of patient education, pharmacological and non-pharmacological treatment. Health professionals are familiar with providing patient education but the knowledge is scarce concerning how this education is experienced by the patients.The aim was to describe patients’ experiences of education in SpA management.Methods: The study had a descriptive design with a qualitative conventional content analysis approach performed in seven steps in accordance with Graneheim & Lundman (1). The analysis aimed to describe and preserve contextual meanings. After coding and subgrouping meaningful parts of the text were merged into categories. Eleven interviews were conducted between 2014-2015 in patients with SpA based on a strategic sampling in order to achieve variation with regard to sex (7 men, 4 women), age (38-66 years), subdiagnoses (5 patients with AS, 6 with USpA), quality of life (EQ5D 0.29-1.0), disease activity (BASDAI 1-6), physical function (BASFI 0-5), and global health (BASG 0-7) .Results: Three categories representing patients’ experiences of patient education in disease management emerged; guiding education, reliable education and available education. Guiding education comprised SpA management including disease knowledge such as symptoms, prognosis, treatment, self-management, climate impact, heredity, and assisting devices. Reliable education meant how and by whom the education was communicated and was considered reliable if it was based on science and communicated by specialists, for example by physician, nurse, PT, dietician and senior patients with experience of rheumatic diseases. The patients experienced difficulties in assessing the large flow of education coming from various sources. Individualized education also increased the reliability. Available education meant that the education can and should be presented in varied formats, and that the amount of information could be chosen. The education could be given orally (through meetings, videos, lectures), in writing (by pamphlets, e-mails, journals, webpages) or obtained through own personal experiences. There were requests to utilize newer media like skype, video and chat forums. Furthermore, individual contacts with healthcare professionals when needed were of importance.Conclusion: This study highlights the importance of obtaining a guiding, reliable and available patient education for management of SpA. Health care professionals need to consider the importance of presenting varied formats of education based on patients’ experiences and expectations.References:1.Graneheim UH, Lundman B.
