    • OBJECTIVES: To increase understanding of the aetiology and pathogenesis of rheumatoid arthritis (RA), genetic and environmental risk factors for RA subsets, defined by the presence or absence of different anticitrullinated protein/peptide antibodies (ACPAs) targeting citrullinated peptides from α-enolase, vimentin, fibrinogen and collagen type II, were investigated. METHODS: 1985 patients with RA and 2252 matched controls from the EIRA case-control cohort were used in the study. Serum samples were assayed by ELISA for the presence of anticyclic citrullinated peptides (anti-CCP) antibodies and four different ACPA fine specificities. Cross-reactivity between ACPAs was examined by peptide absorption experiments. Genotyping was performed for HLA-DRB1 shared epitope (SE) alleles and the PTPN22 gene, while information regarding smoking was obtained by questionnaire. The association of genetic and environmental risk factors with different subsets of RA was calculated by logistic regression analysis. RESULTS: Limited cross-reactivity was observed between different ACPA fine specificities. In total, 17 RA subsets could be identified based on their different ACPA fine specificity profiles. Large differences in association with genetic and environmental determinants were observed between subsets. The strongest association of HLA-DRB1 SE, PTPN22 and smoking was identified for the RA subset which was defined by the presence of antibodies to citrullinated α-enolase and vimentin. CONCLUSION: This study provides the most comprehensive picture to date of how HLA-DRB1 SE, PTPN22 and smoking are associated with the presence of specific ACPA reactivities rather than anti-CCP levels. The new data will form a basis for molecular studies aimed at understanding disease development in serologically distinct subsets of RA.

    • Lung cancer is a common malignancy in rheumatoid arthritis (RA)1,2. Since smoking is a risk factor for both (seropositive) RA and lung cancer, it remains unclear whether RA, in itself, increases lung cancer risk.ObjectivesThe aim of this study was to examine whether and to what extent the increased risk of lung cancer in RA may (or may not) be attributable to smoking, and to examine this association, both in terms of absolute and relative risks, specifically in relation to RA serostatus.MethodsWe performed a population-based cohort study of RA patients and individually matched general population reference individuals identified in Swedish registers and from the EIRA early RA study, prospectively followed for lung cancer occurrence 1995 through 2018. We calculated incidence rates and performed Cox regression to estimate hazard ratios (HR) including 95% confidence intervals (CI) of lung cancer, taking smoking and sero-status into account.ResultsOverall, we included 44,101 RA patients (590 incident lung cancers, 56 per 100,000), and 216,495 matched general population individuals (1,691 incident lung cancers, 33 per 100,000), corresponding to a crude HR (95% CI) of 1.76 (1.60-1.93). In subset analyses this increased risk remained after adjustment for smoking (HR=1.77, 95% CI 1.06-2.97). Compared to general population subjects who were never smokers, RA patients who were ever smokers had almost 7 times higher risk of lung cancer.Positive autoantibody status was associated with an at least doubled risk of lung cancer in ACPA positive patients (vs. ACPA negative patients) and double seropositive (vs. double seronegative) patients after adjusting for comorbidities and smoking (Table 1).Table 1.Number of events, person-years of follow-up, number of events per 100,000 person-years, and relative risk of lung cancer according to autoantibody status in the EIRA sub-cohort. Five Hazard ratios are presented: a) crude; b) adjusted for age, sex, index year, county of residency (model A); c) age, sex, index year, county of residency and comorbidities (renal failure, heart failure, ischemic heart disease, COPD, respiratory infections, hospitalization) (model B) c) all the above plus smoking (model C) and d) as model C with packet-years instead of smoking ever vs. never.No of events (person years of follow-up; No of events/100 000 person years)Crude Hazard ratio (95% CI)Model A Hazard ratio* (95% CI)Model BHazard ratio** (95% CI)Model CHazard ratio** (95% CI)Model D with smoking as pack-years instead of ever/neverPositiveNegativeRF (N=2060)30(49,440; 60.7)6(49,440; 12.1)2.78 (1.16-6.69)3.01 (1.25-7.26)2.82 (1.17-6.82)2.44 (1.01-5.89)2.16 (0.88-5.28)ACPA (N=2060)30(49,440; 60.7)6(49,440; 12.1)3.13 (1.30-7.51)3.43 (1.42-8.25)3.22 (1.33-7.77)2.88 (1.19-6.95)3.29 (1.26-8.58)RF and/or ACPA (N=2060)34(49,440; 68.8)2(49,440; 4.0)6.38 (1.53-26.56)7.62 (1.83-31.83)7.20 (1.72-30.11)6.29 (1.51-26.30)5.76 (1.37-24.21)RF and ACPA (positive vs. double negative)(N=1608)26(38,592; 67.4)2(38,592; 5.2)6.67 (1.58-28.08)7.92 (1.87-33.50)7.08 (1.67-29.98)6.21 (1.47-26.33)5.86 (1.37-25.01)The average absolute five-year risk of lung cancer counting from RA diagnosis was 1.3% in ever-smoking seropositive RA. At 20 years the risk was almost 3% in RA overall, and over 4% for patients who were ever smokers and had at least one autoantibody.ConclusionRA seropositivity is a strong and at least seemingly independent risk factor for lung cancer in RA. The absolute risks point to the potential for regular lung cancer screening, at least in seropositive RA.References[1]Simon TA, Thompson A, Gandhi KK, et al.

    • Initial studies on the immunogenicity of COVID-19 vaccines in patients with immune-mediated inflammatory rheumatic diseases (IRD) reported diminished antibody response in general, and particularly when treated with rituximab or abatacept (1). Additional data are needed, especially for patients with IRD and immunomodulatory treatments.ObjectivesTo elucidate the antibody response after two doses of COVID-19 vaccine in patients with IRD treated with biologic or targeted synthetic disease modifying anti-rheumatic drugs (b/ts DMARDs) as monotherapy or combined with conventional synthetic DMARDS (csDMARDs).MethodsAntibodies against two antigens representing Spike full length protein and Spike S1 and a Nucleocapsid C-terminal fragment (used to confirm previously COVID-19 infection) were measured in serum obtained before and after the second vaccination using a multiplex bead-based serology assay (2). Patients with IRD receiving immunomodulating treatment, followed at a rheumatology department and healthy individuals (controls) were recruited from five Swedish regions. Antibody positivity was classified as the signal passing an antigen specific cutoff based on the mean intensity signal of 12 selected negative pre-pandemic controls plus 6SD for Spike/S1 and 12SD for Nucleocapsid-C. Good vaccine response was defined as having antibodies over cut-off level for both spike antigens. Percentage of responders in each treatment group was compared to controls (Chi2 test). Predictors of antibody response were determined using logistic regression analysis.ResultsIn total, 414 patients (320 RA/JIA/psoriatic arthritis/axial spondylarthritis, 60 systemic vasculitis and 32 other IRD) and 61 controls participated. Patients receiving rituximab (n=145; 65% female; mean age 65years), abatacept (n=21; 77% female; mean age 66 years), IL6 inhibitors (n=77; 74% female; mean age 64years), JAK-inhibitors (n=58; 75% female, mean age 53years), TNF-inhibitors (n=68; 66% female; mean age 44years;), IL17 inhibitors (n=42; 54% female; mean age 44years) and controls (n=61; 74% female, mean age 49years) were studied. Patients receiving IL6 inhibitor (81.0%), abatacept (43.8%) or rituximab (33.8%) had a significantly lower antibody response rate compared to controls (98.4%), further pronounced if combined with csDMARD (p<0.001) (Figure 1). In the adjusted logistic regression analysis, higher age, rituximab, abatacept, concomitant csDMARD but not IL6 inhibitors, concomitant prednisolone, or a vasculitis diagnosis, remained significant predictors of antibody response (Table 1). All vaccines were well tolerated. 14 (3.4%) patients reported an increased activity in their IRD following vaccination.ConclusionIn this nationwide study including IRD patients receiving b/ts DMARDs a decreased immunogenicity of COVID-19 vaccines was observed in patients receiving rituximab, abatacept and to some extent IL-6 inhibitors. Concomitant csDMARD gave further attenuation. Patients on rituximab and abatacept should be prioritized for booster doses of COVID19 vaccine.References[1]Jena, et al.

    • Knowledge of changes over time in baseline characteristics and tumor necrosis factor inhibitor (TNFi) response in bionaïve psoriatic arthritis (PsA) patients treated in routine care is limited.Objectives:To investigate secular trends in baseline characteristics and retention, remission and response rates in PsA patients initiating a first TNFi.Methods:Prospectively collected data on bionaïve PsA patients starting TNFi in routine care from 15 European countries were pooled. According to year of TNFi initiation, three groups were defined a priori based on bDMARD availability: Group A (1999–2008), Group B (2009–2014) and Group C (2015–2018).Retention rates (Kaplan-Meier), crude and LUNDEX adjusted1 remission (Disease Activity Score (DAS28) <2.6, 28-joint Disease Activity index for PsA (DAPSA28) ≤4, Clinical Disease Activity Index (CDAI) ≤2.8) and ACR50 response rates were assessed at 6, 12 and 24 months. No statistical comparisons were made.Results:A total of 17453 PsA patients were included (4069, 7551 and 5833 in groups A, B and C).Patients in group A were older and had longer disease duration compared to B and C. Retention rates at 6, 12 and 24 months were highest in group A (88%/77%/64%) but differed little between B (83%/69%/55%) and C (84%/70%/56%).Baseline disease activity was higher in group A than in B and C (DAS28: 4.6/4.3/4.0, DAPSA28: 29.9/25.7/24.0, CDAI: 21.8/20.0/18.6), and this persisted at 6 and 12 months. Crude and LUNDEX adjusted remission rates at 6 and 12 months tended to be lowest in group A, although crude/LUNDEX adjusted ACR50 response rates at all time points were highest in group A. At 24 months, disease activity and remission rates were similar in the three groups (Table).Table 1.Secular trends in baseline characteristics, treatment retention, remission and response rates in European PsA patients initiating a 1st TNFiBaseline characteristicsGroup A(1999–2008)Group B(2009–2014)Group C(2015–2018)Age, median (IQR)62 (54–72)58 (49–67)54 (45–62)Male, %514847Years since diagnosis, median (IQR)5 (2–10)3 (1–9)3 (1–8)Smokers, %161717DAS28, median (IQR)4.6 (3.7–5.3)4.3 (3.4–5.1)4.0 (3.2–4.8)DAPSA28, median (IQR)29.9 (19.3–41.8)25.7 (17.2–38.1)24.0 (16.1–35.5)CDAI, median (IQR)21.8 (14.0–31.1)20.0 (13.0–29.0)18.6 (12.7–26.1)TNFi drug, % (Adalimumab / Etanercept / Infliximab / Certolizumab / Golimumab)27 / 43 / 30 / 0 / 036 / 31 / 14 / 5 / 1421 / 40 / 21 / 8 / 10Follow up6 months12 months24 monthsGr AGr BGr CGr AGr BGr CGr AGr BGr CRetention rates, % (95% CI)88 (87–89)83 (82–84)84 (83–85)79 (78–80)72 (71–73)72 (71–73)68 (67–69)60 (59–61)60 (59–62)DAS28, median (IQR)2.7 (1.9–3.6)2.4 (1.7–3.4)2.3 (1.7–3.2)2.5 (1.8–3.4)2.2 (1.6–3.1)2.1 (1.6–2.9)2.1 (1.6–3.1)2.0 (1.6–2.9)1.9 (1.5–2.6)DAPSA28, median (IQR)10.6 (4.8–20.0)9.5 (3.9–18.3)8.7 (3.6–15.9)9.1 (4.1–17.8)7.7 (3.1–15.4)7.6 (2.9–14.4)6.7 (2.7–13.7)6.6 (2.7–13.5)5.9 (2.4–11.8)CDAI, median (IQR)7.8 (3.0–15.2)8.0 (3.0–15.0)6.4 (2.6–12.2)6.4 (2.5–13.0)6.2 (2.5–12.1)5.8 (2.2–11.4)5.0 (2.0–11.0)5.5 (2.0–11.2)5.0 (2.0–9.0)DAS28 remission, %, c/L47 / 4255 / 4661 / 5153 / 4362 / 4566 / 4864 / 4268 / 3775 / 41DAPSA28 remission, %, c/L22 / 1926 / 2228 / 2325 / 2031 / 2232 / 2336 / 2334 / 1938 / 21CDAI remission, %, c/L23 / 2123 / 1926 / 2227 / 2127 / 2029 / 2134 / 2231 / 1735 / 19ACR50 response, %, c/L26 / 2322 / 1824 / 2027 / 2223 / 1721 / 1523 / 1518 / 1014 / 8Gr, Group; c/L, crude/LUNDEX.Conclusion:Over the past 20 years, patient age, disease duration and disease activity level at the start of the first TNFi in PsA patients have decreased. Furthermore, TNFi retention rates have decreased while remission rates have increased, especially remission rates within the first year of treatment. These findings may reflect a greater awareness of early diagnosis in PsA patients, a lowered threshold for initiating TNFi and the possibility for earlier switching in patients with inadequate treatment response.References:[1]Arthritis Rheum 2006; 54: 600-6.Acknowledgements:Novartis Pharma AG and IQVIA for supporting the EuroSpA Research Collaboration Network.Disclosure of Interests:Sara Nysom Christiansen Speakers bureau: BMS and GE, Grant/research support from: Novartis, Lykke Midtbøll Ørnbjerg Grant/research support from: Novartis, Simon Horskjær Rasmussen: None declared, Anne Gitte Loft Speakers bureau: AbbVie, Janssen, Lilly, MSD, Novartis, Pfizer, UCB, Consultant of: AbbVie, Janssen, Lilly, MSD, Novartis, Pfizer, UCB, Grant/research support from: Novartis, Johan K Wallman Consultant of: Celgene, Eli Lilly, Novartis, Florenzo Iannone Speakers bureau: Abbvie, MSD, Novartis, Pfizer and BMS, Brigitte Michelsen Consultant of: Novartis, Grant/research support from: Novartis, Michael J.

    • OBJECTIVES: To confirm and define the genetic association of STAT4 and systemic lupus erythematosus, investigate the possibility of correlations with differential splicing and/or expression levels, and genetic interaction with IRF5. METHODS: 30 tag SNPs were genotyped in an independent set of Spanish cases and controls. SNPs surviving correction for multiple tests were genotyped in 5 new sets of cases and controls for replication. STAT4 cDNA was analyzed by 5'-RACE PCR and sequencing. Expression levels were measured by quantitative PCR. RESULTS: In the fine-mapping, four SNPs were significant after correction for multiple testing, with rs3821236 and rs3024866 as the strongest signals, followed by the previously associated rs7574865, and by rs1467199. Association was replicated in all cohorts. After conditional regression analyses, two major independent signals represented by SNPs rs3821236 and rs7574865, remained significant across the sets. These SNPs belong to separate haplotype blocks. High levels of STAT4 expression correlated with SNPs rs3821236, rs3024866 (both in the same haplotype block) and rs7574865 but not with other SNPs. We also detected transcription of alternative tissue-specific exons 1, indicating presence of tissue-specific promoters of potential importance in the expression of STAT4. No interaction with associated SNPs of IRF5 was observed using regression analysis. CONCLUSIONS: These data confirm STAT4 as a susceptibility gene for SLE and suggest the presence of at least two functional variants affecting levels of STAT4. Our results also indicate that both genes STAT4 and IRF5 act additively to increase risk for SLE.

    • Immune-mediated inflammatory diseases (IMIDs) are heterogeneous and complex conditions with overlapping clinical symptoms and elevated familial aggregation, which suggests the existence of a shared genetic component. In order to identify this genetic background in a systematic fashion, we performed the first cross-disease genome-wide meta-analysis in systemic seropositive rheumatic diseases, namely, systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis and idiopathic inflammatory myopathies.MethodsWe meta-analysed ~6.5 million single nucleotide polymorphisms in 11 678 cases and 19 704 non-affected controls of European descent populations. The functional roles of the associated variants were interrogated using publicly available databases.ResultsOur analysis revealed five shared genome-wide significant independent loci that had not been previously associated with these diseases: NAB1, KPNA4-ARL14, DGQK, LIMK1 and PRR12. All of these loci are related with immune processes such as interferon and epidermal growth factor signalling, response to methotrexate, cytoskeleton dynamics and coagulation cascade. Remarkably, several of the associated loci are known key players in autoimmunity, which supports the validity of our results. All the associated variants showed significant functional enrichment in DNase hypersensitivity sites, chromatin states and histone marks in relevant immune cells, including shared expression quantitative trait loci. Additionally, our results were significantly enriched in drugs that are being tested for the treatment of the diseases under study.ConclusionsWe have identified shared new risk loci with functional value across diseases and pinpoint new potential candidate loci that could be further investigated. Our results highlight the potential of drug repositioning among related systemic seropositive rheumatic IMIDs.

  • EULAR recommendations for cardiovascular disease risk management in patients with rheumatoid arthritis and other forms of inflammatory joint disorders: 2015/2016 update
  • 2017
  • Ingår i: Ann Rheum Dis. - : BMJ. - 0003-4967 .- 1468-2060. ; 76:1, s. 17-28

    • Patients with rheumatoid arthritis (RA) and other inflammatory joint disorders (IJD) have increased cardiovascular disease (CVD) risk compared with the general population. In 2009, the European League Against Rheumatism (EULAR) taskforce recommended screening, identification of CVD risk factors and CVD risk management largely based on expert opinion. In view of substantial new evidence, an update was conducted with the aim of producing CVD risk management recommendations for patients with IJD that now incorporates an increasing evidence base. A multidisciplinary steering committee (representing 13 European countries) comprised 26 members including patient representatives, rheumatologists, cardiologists, internists, epidemiologists, a health professional and fellows. Systematic literature searches were performed and evidence was categorised according to standard guidelines. The evidence was discussed and summarised by the experts in the course of a consensus finding and voting process. Three overarching principles were defined. First, there is a higher risk for CVD in patients with RA, and this may also apply to ankylosing spondylitis and psoriatic arthritis. Second, the rheumatologist is responsible for CVD risk management in patients with IJD. Third, the use of non-steroidal anti-inflammatory drugs and corticosteroids should be in accordance with treatment-specific recommendations from EULAR and Assessment of Spondyloarthritis International Society. Ten recommendations were defined, of which one is new and six were changed compared with the 2009 recommendations. Each designated an appropriate evidence support level. The present update extends on the evidence that CVD risk in the whole spectrum of IJD is increased. This underscores the need for CVD risk management in these patients. These recommendations are defined to provide assistance in CVD risk management in IJD, based on expert opinion and scientific evidence.

    • To develop response criteria for adult dermatomyositis (DM) and polymyositis (PM). Expert surveys, logistic regression, and conjoint analysis were used to develop 287 definitions using core set measures. Myositis experts rated greater improvement among multiple pairwise scenarios in conjoint analysis surveys, where different levels of improvement in 2 core set measures were presented. The PAPRIKA (Potentially All Pairwise Rankings of All Possible Alternatives) method determined the relative weights of core set measures and conjoint analysis definitions. The performance characteristics of the definitions were evaluated on patient profiles using expert consensus (gold standard) and were validated using data from a clinical trial. The nominal group technique was used to reach consensus. Consensus was reached for a conjoint analysis-based continuous model using absolute per cent change in core set measures (physician, patient, and extramuscular global activity, muscle strength, Health Assessment Questionnaire, and muscle enzyme levels). A total improvement score (range 0–100), determined by summing scores for each core set measure, was based on improvement in and relative weight of each core set measure. Thresholds for minimal, moderate, and major improvement were ≥20, ≥40, and ≥60 points in the total improvement score. The same criteria were chosen for juvenile DM, with different improvement thresholds. Sensitivity and specificity in DM/PM patient cohorts were 85% and 92%, 90% and 96%, and 92% and 98% for minimal, moderate, and major improvement, respectively. Definitions were validated in the clinical trial analysis for differentiating the physician rating of improvement (p<0.001). The response criteria for adult DM/PM consisted of the conjoint analysis model based on absolute per cent change in 6 core set measures, with thresholds for minimal, moderate, and major improvement.

    • Limited therapies are available for patients with idiopathic inflammatory myopathy (IIM), a heterogenous group of chronic, systemic, autoimmune inflammatory diseases characterized by progressive muscle weakness and/or distinct skin rashes.1 Abatacept, a selective co-stimulation modulator, may be a useful treatment option.2ObjectivesTo evaluate efficacy, safety, and tolerability of abatacept + standard of care (SOC) in patients with IIM compared with SOC alone (placebo).MethodsA 24-week, randomized, double-blind, placebo-controlled phase 3 trial of SC abatacept (125 mg weekly) + SOC (corticosteroids and immunosuppressants alone or combined; NCT02971683) in patients with active, treatment-refractory IIM (Manual Muscle Testing-8 [MMT-8] ≤ 135) was performed. Primary endpoint was proportion of patients meeting International Myositis Assessment and Clinical Studies definition of improvement (IMACS DOI) at week 24. Change from baseline in myositis Functional Index-2 (FI-2), HAQ-DI, Myositis Disease Activity Assessment Tool (MDAAT), and Myositis Response Criteria (MRC) were secondary endpoints with safety. Post hoc analyses by disease subtype were performed.ResultsOverall, 148 patients were randomized (75 abatacept; 73 placebo); IIM subtypes were dermatomyositis (DM; 53.3% vs 57.5%), polymyositis (PM; 25.3% vs 34.2%), and autoimmune necrotizing myopathy (ANM; 21.3% vs 8.2%). Mean baseline MMT-8 and HAQ-DI scores were 112.7 and 1.5, respectively. Approximately 90% of patients completed week 24. Week 24 IMACS DOI rates were abatacept 56.0% vs placebo 42.5% (adjusted odds ratio, 1.8 [95% CI, 0.9–3.5]; P = 0.083). Pre-specified IMACS DOI analysis showed no differences for patients with DM but notable benefit for those with non-DM subtypes, PM and ANM (Table 1). Secondary endpoints showed similar differences (Table 1). MRC at day 169 by category is shown in Figure 1. Proportion of AEs (69.3% and 75.3%) and serious AEs (5.3% and 5.5%) were similar in the abatacept and placebo arms.Table 1.Primary and secondary (mean change from baseline at week 24) endpointsOutcomeIIMAbataceptPlaceboNominal P value (abatacept vs placebo) or adjusted mean difference from placebo (95% CI)IMACS DOI,a n/N (%)All42/75 (56.0)31/73 (42.5)P = 0.083DM22/40 (55.0)21/42 (50.0)P = 0.679Non-DM20/35 (57.1)10/31 (32.3)P = 0.040FI-2All4.1 (1.3)1.2 (1.4)2.9 (0 to 5.8)DM2.3 (1.6)0.3 (1.4)1.9 (−2.3 to 6.2)Non-DM3.2 (1.4)−0.6 (1.5)3.7 (−0.3 to 7.8)HAQ-DIAll−0.31 (0.07)0.20 (0.07)−0.12 (−0.28 to 0.04)DM−0.31 (0.08)−0.19 (0.07)−0.11 (−0.32 to 0.10)Non-DM−0.25 (0.09)−0.07 (0.09)−0.18 (−0.44 to 0.07)MDAAT, Extramuscular Global Activity, (95% CI)bAll−1.56 (−1.96 to −1.16)−1.40 (−1.81 to −0.99)−0.16 (−0.63 to 0.30)DM−1.90 (−2.43 to −1.37)−1.85 (−2.35 to 1.36)−0.05 (−0.77 to 0.68)Non-DM−1.09 (−1.46 to −0.72)−0.85 (−1.27 to −0.43)−0.24 (−0.80 to 0.32)MMT-8All12.9 (1.9)11.0 (2.0)1.8 (−2.7 to 6.4)DM14.4 (2.2)14.0 (2.2)0.4 (−5.7 to 6.4)Non-DM12.1 (2.5)7.8 (2.7)4.3 (−3.0 to 11.7)Physician Global AssessmentbAll−2.89 (0.30)−2.69 (0.30)−0.20 (−0.92 to 0.52)DM−2.78 (0.29)−2.43 (0.28)−0.35 (−1.15 to 0.46)Non-DM−2.35 (0.43)−2.21 (0.48)−0.14 (−1.43 to 1.15)Patient Global AssessmentbAll−1.4 (0.31)−0.98 (0.32)−0.38 (−1.11 to 0.35)DM−1.4 (0.33)−1.4 (0.31)−0.00 (−0.91 to 0.90)Non-DM−1.2 (0.41)−0.3 (0.44)−0.93 (−2.14 to 0.29)Data are adjusted mean change from baseline score (SE) unless stated.aDefined as improvement of ≥ 20% in 3 IMACS core measures, worsening by ≥ 25% in ≤ 2 IMACS core measure scores, and a reduction of < 25% in MMT-8; b100 mm visual analog scale.ConclusionIn this double-blind trial of SC abatacept vs placebo, abatacept failed to meet primary or secondary endpoints.

  • INTEGRATION OF GWAS AND EPIGENETIC STUDIES IDENTIFIES NOVEL GENES THAT ALTER EXPRESSION IN THE MINOR SALIVARY GLAND IN SJOGREN'S DISEASE
  • 2022

    • Sjogren’s disease (SjD) is an autoimmune disease characterized by reduced function of exocrine glands (i.e., salivary and lacrimal glands). Epithelial cell damage resulting from lymphocytic infiltration has been implicated in SjD etiology [1]. How genetic and epigenetic changes influence epithelial-immune cell interactions in SjD pathogenesis remain understudied.ObjectivesEvaluate the role of SjD risk loci in salivary gland tissue to gain insights into the potential genes involved in salivary gland dysfunction.MethodsSNPs from 16 regions with SNP-SjD associations (P<5x10-8) in our GWAS study (3232 SjD cases) and meta-analysis of ImmunoChip data (619 SjD cases) [2] were interrogated for eQTLs using Genotype-Tissue Expression (GTEx) minor salivary gland data. Subsequent analysis identified genes that were both eQTLs in the minor salivary gland and significantly expressed in RNA-seq and ATAC-seq data from the submaxillary salivary gland epithelial cell line, A253. Pathway enrichment analysis was performed using gProfiler on the genes where coalescence of eQTL, RNA-seq, and ATAC-seq data was observed. To further validate the results, we performed transcriptome-wide association study (TWAS) analysis using GWAS summary statistics and minor salivary gland eQTL GTEx data.ResultsIn total, 5884 genome-wide significant SNPs from 16 SjD risk loci were identified as potential minor salivary gland eQTLs using two discovery thresholds: p(FDR)<0.05 provided by eQTL study (3566 SNPs) and p(FDR)>0.05 and p<0.05 in eQTL study (2318 SNPs). Further analysis revealed 10 SjD risk loci with SNPs that were minor salivary gland eQTLs for a total of 155 unique genes that had a coalescence of RNA- and ATAC-seq data in A253 cells. Many SNPs altered the expression of the nearest gene to the risk allele (i.e., index gene), such as IRF5 and TNPO3 on chromosome 7 at 128Mb; however, this locus had 12 additional genes that were eQTLs in minor salivary gland. In contrast, other loci had no reported eQTLs for the index gene, but several reported eQTLs for other genes, such TYK2 on chromosome 19 at 10Mb that showed no change in TYK2 expression but eQTLs for 8 distant genes, including ICAM1. Pathway enrichment analysis revealed an enrichment in Butyrophilin (BTN) family interactions (R-HSA-8851) (PAdj=1.564x10-5), including the BTN2A1, BTN2A2, BTN3A1, BTN3A2 and BTN3A3 gene cluster in the MHC region. In further support, TWAS of the minor salivary gland and the SjD GWAS summary statistics (after Bonferroni correction) showed association between SjD and BTN3A2 (p=1.24x10-42), as well as many other loci in the MHC region. In addition, several long non-coding (lnc) RNAs on chromosome 17 were significant, peaking at RP11-259G18.1 (p=4.43x10-10).ConclusionThis study shows that SjD-associated risk alleles influence disease by altering gene expression in immune cells and minor salivary glands. Further, our analysis suggests that altered gene expression in the minor salivary gland expands beyond effects on the index gene to several genes on each locus. Interestingly, we observed minor salivary gland eQTLs for several BTN family genes, which act as cell-surface binding partners to regulate cell-cell interactions, including interactions between epithelial cells and activated T cells [3]. Future work will assess chromatin-chromatin-interactions within the 10 SjD risk loci in salivary gland cells and tissues to map local chromatin regulatory networks that regulate gene expression. Additional transcriptional studies of SjD minor salivary gland tissues will provide further insights into how altered gene expression in the salivary gland influences SjD pathology.References[1]Verstappen.

  • International recommendations for the assessment of autoantibodies to cellular antigens referred to as anti-nuclear antibodies
  • 2014

    • Anti-nuclear antibodies (ANA) are fundamental for the diagnosis of autoimmune diseases, and have been determined by indirect immunofluorescence assay (IIFA) for decades. As the demand for ANA testing increased, alternative techniques were developed challenging the classic IIFA. These alternative platforms differ in their antigen profiles, sensitivity and specificity, raising uncertainties regarding standardisation and interpretation of incongruent results. Therefore, an international group of experts has created recommendations for ANA testing by different methods. Two groups of experts participated in this initiative. The European autoimmunity standardization initiative representing 15 European countries and the International Union of Immunologic Societies/World Health Organization/Arthritis Foundation/Centers for Disease Control and Prevention autoantibody standardising committee. A three-step process followed by a Delphi exercise with closed voting was applied. Twenty-five recommendations for determining ANA (1-13), anti-double stranded DNA antibodies (14-18), specific antibodies (19-23) and validation of methods (24-25) were created. Significant differences between experts were observed regarding recommendations 24-25 (p<0.03). Here, we formulated recommendations for the assessment and interpretation of ANA and associated antibodies. Notably, the roles of IIFA as a reference method, and the importance of defining nuclear and cytoplasmic staining, were emphasised, while the need to incorporate alternative automated methods was acknowledged. Various approaches to overcome discrepancies between methods were suggested of which an improved bench-to-bedside communication is of the utmost importance. These recommendations are based on current knowledge and can enable harmonisation of local algorithms for testing and evaluation of ANA and related autoantibodies. Last but not least, new more appropriate terminologies have been suggested.

    • To evaluate gender differences in score on 28-joint Disease Activity Score (DAS28), Health Assessment Questionnaire (HAQ) and Signals Of Functional Impairment (SOFI) and to relate these scores to radiographic joint destruction.Methods:In all, 549 patients with early RA (62% women) from the BARFOT (for “Better Anti-Rheumatic FarmacOTherapy”) study were included. At baseline, 1, 2 and 5 years DAS28, HAQ and SOFI scoring, and radiographs of hands and feet were performed. The radiographs were scored using the van der Heijde–Sharp score.Results:In women the DAS28 was significantly higher than in men due to higher scores for general health and tender joints. Likewise, HAQ and VAS pain were rated significantly higher in women. The SOFI score was worse in men during the first 2 years, depending on higher upper limb scores. Total Sharp score (TotSharp), erosion score and joint space narrowing score did not differ between the sexes at any time point. The DAS28 area under the curve (AUC) correlated significantly with TotSharp at 5 years in both genders (r = 0.316, r = 0.313) mainly owing to swollen joints and erythrocyte sedimentation rate (ESR). The SOFI AUC correlated significantly with TotSharp in women (r = 0.135 to 0.220) but not in men.Conclusions:Despite a similar degree of radiographic joint destruction women had, compared with men, worse scores for DAS28 and HAQ, possibly due to higher pain perception and less muscular strength and perhaps because men overestimate their functional capacity.

  • Less pain and activity limitations in today's early RA patients compared with patients diagnosed 10 years earlier (the swedish TIRA-project)
  • 2014
  • Ingår i: EULAR 2014: Scientific Abstracts. - : BMJ. ; , s. 141-142
  • Konferensbidrag (refereegranskat)abstract
    • Background: Over the last decades the RA-treatment strategies have changed considerably. Routines for early RA diagnosis and instituted disease modifying anti rheumatic drugs (DMARDs) have been established. In the early 2000s biologic agents also became available for treatment purposes. Despite these altered and improved strategies RA patients continue to report pain and activity limitations; women more so than men.Objectives: To study differences regarding pain and activity limitations during the first three years after diagnosis of RA in today's patients compared with patients diagnosed 10 years earlier from a gender perspective.Methods: This study was based on patients recruited to the project “early interventions in RA” (TIRA). In the first cohort (TIRA-1) 320 patients were included during 1996-1998. In the second cohort (TIRA-2) 463 patients were included during 2006-2008. Disease activity score 28 joint count (DAS-28) and medication were registered. Pain intensity (VAS), bodily pain (BP) in Short Form36 (SF-36) and activity limitation (Health Assessment Questionnaire, HAQ) were reported at inclusion and at follow-ups after one, two and three years.Results: Disease activity did not differ between cohorts at inclusion, but was significant lower at the follow ups in the TIRA-2 cohort compared with the TIRA-1 cohort. Patients in TIRA2 were prescribed traditional DMARD:s and biologic agents more frequent than in TIRA-1. The TIRA-2 patients reported significantly higher pain intensity and activity limitations at inclusion but lower pain intensity and activity limitations at all follow-ups than TIRA-1 patients. There were no significant differences between cohorts regarding bodily pain at inclusion, but thereafter the TIRA-2 patients showed significant lower bodily pain than the TIRA-1 patients. Men reported lower activity limitation than women in TIRA-1; otherwise there were no gender differences in TIRA-1. In TIRA-2, there were no significant gender differences regarding pain at inclusion. However, men reported lower pain than women at all follow-ups. Women, in turn, reported significantly higher activity limitations at all time points in TIRA-2. Pain and activity limitations were significantly reduced from inclusion to the one year follow-up but remained stable thereafter.Conclusions: Both women and men in today's early RA patient cohort report lower pain and less activity limitations at the follow ups after diagnosis of RA compared to 10 years earlier. However, both activity limitations and bodily pain are still pronounced.

    • Background Experience of balance in everyday activities where work is an essential part is important to health and well-being, as has also been observed in previous studies in people with rheumatoid arthritis (RA). The Valued life activity scale (VLA-swe) is a questionnaire in which patient’s first report if the separate activities are valued or not to perform and secondly difficulties to perform these activities. Occupational Balance Questionnaire (OBQ) focuses on satisfaction with the amount and variation of occupations.Objectives The objectives were to 1) describe the relationship between performance of valued activities and experienced occupational balance, and to 2) identify aspects associated with low occupational balance in persons with RA.Methods 368 persons (age 18–65 years, 77% women) with RA responded to a questionnaire measuring occupational balance (OBQ) and performance of valued life activities (VLA-swe). Other aspects of interest were activity limitations measured by Health Assessment Questionnaire (HAQ), pain (measured by VAS), continuous stress (stressed continuously for more than a month during the last 12 months), children at home, education, and living situation. The relation between OBQ and performance in VLA across genders and Workers/Non-workers were analysed using non-parametric correlation analyses. To identify the impact of different aspects on the likelihood that participants would report lower occupational balance, OBQ was analysed using workers/nonworkers, stress, gender, age, pain and difficulties performing valued activities as independent variables in logistic regressions models. The study was approved by the Regional Ethics Committee (Dnr2011/452–31).Results The OBQ was significantly related to difficulties to perform valued activities reported by VLA (r=-0.41, p<0.001). Having more difficulties performing valued activities was the strongest predictor of lower occupation balance and increased the risk of reporting lower occupation balance with nearly five times (OR=4.54, p 0.001). Continuous stress increased the risk of having lower occupation balance more than three times (OR=3.27, p<0.0001) than those who not reported being stressed. The other variables show no significant impact on the likelihood that the participants would report lower occupational balance.Conclusions The results showed support for the relationship between occupation balance and performance of valued life activities and highlights to identify what’s important for the individual and to assume that in the rehabilitation. The results also show the importance of ability to manage stress, in order to enable for retaining ability to work and achieve high occupational balance.

  • Long term trajectories of chronic widespread pain : a 21-year prospective cohort latent class analysis
  • 2019
  • Ingår i: Annals of the Rheumatic Diseases. - London, UK : BMJ Publishing Group Ltd. - 0003-4967 .- 1468-2060. ; 78:Suppl 2, s. 239-239
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Chronic widespread pain (CWP) is common (population prevalence of approximately 10%) and has a significant impact on the individual, healthcare, and society. Currently little is known about the actual course of CWP over time, in particular the pathways to the development and maintenance of CWP. One useful way to understand these pathways is to identify common clusters of people who share pain trajectories. Such information is clinically useful to identify factors that predict development, persistence, and resolution of CWP.Objectives: To identify different longitudinal pain trajectories over a period of 21 years.Methods: A 21-year longitudinal open-population cohort of n=1858 adults (aged 20-74) who completed surveys relating to their pain status in at least three of the five time points 1995, 1998, 2003, 2007, and 2016. Pain status (presence of persistent pain) was ascertained from a report of painful regions (0-18) on a pain mannequin and categorised into: NCP (No chronic pain), CRP (Chronic regional pain) and CWP (chronic widespread pain). Latent Class Growth Analysis (LCGA) was carried out based on these categories. Participants were assigned to a trajectory cluster where the posterior probability was the highest. Model fit was assessed by statistical indices and clinical interpretations of clusters.Results: LCGA identified five clusters describing different pathways of NCP, CRP and CWP over the 21 years. The cluster “Persistent NCP” was the most common pathway (n = 1052, 57%) representing those with no chronic pain over the whole time period. The “Persistent CRP or Migration from CRP to NCP” cluster included 411 individuals (22%) representing a group with stable or improving regional pain. In the groups who were shown to increase pain status, the “Migration from NCP to CRP or CWP” cluster included 92 individuals (5%), and there were 184 individuals (10%) in the cluster “Migration from CRP to CWP” representing a group with regional pain who developed CWP. The final cluster “Persistent CWP” included 119 individuals (6%) representing those with stable CWP throughout the time period. Figure 1 presents the mean number of pain sites over time by cluster.Conclusion: This study showed that whilst half of adults report no chronic pain over 21 years, a substantial proportion develop CWP or have persistent CWP over this time period. Whilst a common trajectory was movement from chronic regional pain to no chronic pain, a pattern of improving CWP was not seen suggesting this is an uncommon trajectory. This is the first study to show long-term trajectories for CWP, and further work is now required to understand factors that may identify individuals at risk of worsening pain status and factors that might promote improvement. These identified pathways of chronic pain over a lifespan improve the understanding of long-term development of chronic pain and chronic widespread pain. © Aili et al. 2019. No commercial re-use.

  • Passive coping strategies but not physical function are associated with worse mental health, in women with chronic widespread pain – a mixed method study
  • 2019
  • Ingår i: Annals of the Rheumatic Diseases. - London, UK : BMJ Publishing Group Ltd. - 0003-4967 .- 1468-2060. ; 78:Suppl 2, s. 2159-2159
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Chronic widespread pain (CWP) is a common condition (approximately 10% prevalence), that affects women twice as often as men. There is a lack of knowledge in how different coping strategies relates to health status during CWP development in a general population.Objectives: To explore different ways of coping with CWP and to relate the different coping strategies to health-related factors, before and after developing CWP.Methods: A sequential explorative mixed methods study including 19 women 45-67 of age, who had reported CWP in a survey 2016, but not in 1995. Individual interviews were analysed with a phenomenographic approach, and resulted in four categories of coping strategies. These categories were further explored with regard to four dimensions of health status (physical function, bodily pain, vitality and mental health) as measured by SF-36 (0-100, a lower score indicates more disability) and sleep problems measured both in 1995, and 2016.Results: The qualitative analysis revealed four categories representing different coping strategies, where each woman was labelled by the most dominant category; the mastering woman, the persistent woman, the compliant woman and the conquered woman. The first two categories emerged as being active coping strategies, and the latter two as passive. Women with passive strategies reported significantly lower vitality (median 57.5 vs 75, p=0.007) and worse mental health (median 54 vs 93, p=0.021) in 1995, before they had developed CWP compared with those with active coping strategies. No differences were seen between the groups on physical function, bodily pain or sleep.In 2016, there were still a difference between the passive and active group regarding mental health (median 56 vs 80, p=0.022), but not for vitality (median 35 vs 40, p=0.707). No differences were seen between the groups on physical function or bodily pain. All eight women with passive strategies reported problems with sleep in 2016, as compared to 6 of the 11 women with active strategies (p=0.045).Conclusion: Women that reported CWP in 2016, but not in 1995, described both active and passive coping strategies. The qualitative findings were associated with differences in vitality and mental health already in 1995, before they had developed CWP. Further, those with passive coping strategies reported worse health with regard to mental health and sleep problems in 2016. Interestingly, the groups did not differ in bodily pain or physical function neither in 1995 nor in 2016, which implicates the importance for the clinician to take the typical coping strategy into consideration, when meeting these patients in clinical settings. © Aili, Bergman, Bremander, Haglund & Larsson 2019.

    • Background: If localised pain represent one end of a pain spectra, with overall better general health, chronic widespread pain (CWP) and fibromyalgia represent the other end of the spectra with worse general health and more comorbidities with other somatic diseases and mental illness. Sleep problems and fatigue are common among individuals reporting CWP and previous research indicate that sleep problems may be an important predictor for pain prognosis.Objectives: The aim of this population-based study was to investigate if sleep problems and fatigue predict the onset of CWP 5 and 18 years later.Methods: In order to get more stable baseline classifications of CWP, a wash-out period was used, including only individuals who had not reported CWP (according to ACR 1990 criteria for fibromyalgia) at baseline (−98) and three years prior baseline (−95). In all, data from 1249 individuals entered the analyses for the 5 year follow-up (−03) and 791 entered for the 18 year follow-up (−16). Four parameters related to sleep (difficulties initiating sleep, maintaining sleep, early morning awakening and non-restorative sleep), and one parameter related to fatigue (SF-36 vitality scale) were investigated as predictors for CWP. Binary logistic regression analysis were used for analyses.Results: All investigated parameters predicted the onset of CWP five years later (problems with initiating sleep (OR 1.91; 1.16–3.14), maintaining sleep (OR 1.85; 1.14–3.01), early awakening (OR 2.0; 1.37–3.75), non-restorative sleep (OR 2.27; 1.37–3.75) and fatigue (OR 3.70; 1.76–7.84)) in a model adjusted for age, gender, socio-economy and mental health. All parameters except problems with early awakening predicted the onset of CWP also 18 years later. In all, 785 individuals did not report any of the sleeping problems at baseline (fatigue not included), 268 reported one of the problems, 167 two, 128 three and 117 subjects reported to have all four sleep problems. Reporting all four sleep problems was significantly associated with CWP at follow-up at both time points when adjusting for age, gender, socio economy and mental health (OR 4.00; 2.03–7.91 and OR 3.95; 1.90–8.20); adjusting for age, gender, socio economy and number of pain regions (OR 2.94; 1.48–5.82 and OR 2.65; 1.24–5.64) and in a model adjusting for age, gender, socio economy and pain severity (OR 2.97;1.53–5.76; and OR 3.02;1.47–6.21) for the 5 year and 18 year follow-up respectively, compared to not reporting any of the sleep problems at baseline.Conclusions: Both sleeping problems and fatigue predicts the onset of CWP 5- and 18 years later. The results highlight the importance of the assessment of sleep quality in the clinic.

  • Women’s experiences of coping with chronic widespread pain – a qualitative study
  • 2018
  • Ingår i: Annals of the Rheumatic Diseases. - London : BMJ Publishing Group Ltd. - 0003-4967 .- 1468-2060. ; 77, s. 1815-1815
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Approximately ten percent of the population report chronic widespread pain (CWP), the condition is more common among women than men. For most people, the pain interferes with many aspects of every-day life and implies large consequences. However, the group reporting CWP is heterogeneous and there is a need for better understanding of the different strategies used for coping with pain in every-day life.Objectives: The purpose of this study was to describe women’s experiences of how to cope with CWP.Methods: The study had a descriptive design with a qualitative content analysis approach. Individual interviews were conducted with 19 women, 31–66 of age, who had reported CWP in a survey 2016. CWP was defined according to the 1990 ACR criteria for fibromyalgia. To be considered chronic, the pain should have persisted for more than three months during the last 12 months. A manifest qualitative content analysis was used to analyze the main question “How do you cope with your chronic widespread pain?” The analysis resulted in four categories.Results: Women described their coping with CWP in four different ways; to take control, to continue as usual, to follow instructions and to rest. To take control meant to make deliberate decisions to handle everyday day life. It also meant to take care of oneself, to think positive and to exercise at an adequate level. To continue as usual meant not to listen to body signals and either to ignore or accept the pain. To follow instructions meant listening to the health professionals and following advices, but without taking any part of the responsibility for the treatment outcome. To rest meant to perceive an unreasonable need for recovery, to resign and let the pain set the terms for the daily living.Conclusions: Women expressed different ways of coping with CWP including both active and passive strategies. The coping strategies included two dimensions, where one ranged from actively taking control over the pain, to passively following instructions and the other from actively continue as usual by either accepting or ignoring the pain to passively rest and being mastered by pain.
