- The role of psychosocial conditions on the disease course of rheumatoid arthritis (RA) is getting increased attention. In our previous study, low social support and low decision latitude at work were associated with known modifiable risk factors for RA disease development, such as smoking and low educational level (1). Further, smoking and low educational level have previously been shown to be associated with worse RA disease outcome (2-4). Whether psychosocial characteristics are related to RA disease outcome needs further investigation.Objectives:To investigate the relationship between two psychosocial characteristics: low social support and low decision latitude at work, and achievement of remission in patients with RA.Methods:At inclusion in the Swedish EIRA study, incident RA cases (N=3724) and controls (N=5937), matched for age, sex and residential area, responded to a questionnaire including questions on social support and decision latitude at work. The answers were recoded into separate scores and the distribution of the scores among controls were used to define the exposures. Low social support and low decision latitude at work, respectively, among patients, were set as the level corresponding to the lowest quartile among controls, and were compared with scores corresponding to the remaining three quartiles.The outcome, disease activity score 28-joint count (DAS28) remission, defined as DAS28<2.6, was captured through linkage with the Swedish Rheumatology Quality Register (SRQ) with data available from diagnosis for 2693 out of 3700 cases for social support and for 847 out of 1248 cases for decision latitude at work.Logistic regression was used to evaluate the association between low social support or low decision latitude at work, respectively, and the chance of remission at the time-points 3 months, 12 months and 60 months after inclusion. All results were adjusted for age, sex and residential area and the fully adjusted models were also adjusted for smoking, obesity, physical activity and educational level.Results:Low social support (n=655) was associated with a reduced chance for remission at all three time points in the model adjusted for age, sex and residential area; OR 3 months 0.77 (95% CI 0.61-0.97), OR 12 months 0.78 (95% CI 0.64-0.95) OR 60 months 0.77 (95% CI 0.59-0.99). This association was diminished after further adjustment. After stratifying for sex, this association was enhanced in women but inverse among men (Figure 1).No association between low decision latitude at work (n=166) and chance for remission was observed neither in the analyses stratified for matching variables, nor in the full model. This result was only marginally changed after stratifying for sex (Figure 1).Conclusion:Low social support was associated with lower chance of remission in early RA, but the association was not independent of other risk factors for worse outcome (smoking, physical activity, obesity and low educational level).The interrelationship between social stressors and previously known risk factors for worse outcome highlights the importance of supportive actions at many levels to increase the possibility for the individual to make healthy decisions.References:[1]Hedenstierna. et al.

- Pulmonary manifestations in rheumatoid arthritis (RA) are common comorbidities but the underlying mechanisms are largely unknown. We found in a previous study 3 SNPs associated with pulmonary fibrosis (PF); rs35705950 (MUC5B), rs111521887 (TOLLIP), and rs2609255 (FAM13A) besides age, rheumatoid factor positivity and methotrexate treatment.ObjectivesTo evaluate for the added value of a multiplex of anti-citrullinated peptide antibodies (ACPA) for the development of pulmonary fibrosis (PF) in an inception cohort of RA patients.MethodsA total of 1184 patients with early RA were consecutively included and followed prospectively from the date of diagnosis (index date) until death or until 31 December 2016. The diagnosis of PF was based on high resolution tomography. The presence of 21 ACPA fine specificities were analysed in plasma sampled at index date, using a custom-made microarray chip (Thermo Fisher Scientific, Uppsala, Sweden). Data on both ACPA and genetic data was available for 841 RA patients, of whom 50 developed PF. Associations were analysed using logistic regression analysis and presented as the odds ratio (OR) with the 95% confidence interval (CI). Models were adjusted for sex, age, DAS28 and presence of RF at RA diagnosis, smoking ever, and HLA-SE and in a second step for the three SNPs (.rs35705950, rs111521887 and rs2609255), respectively.ResultsIn unadjusted analyses eight ACPA reactivities were found associated with PF development (p< 0.05-0.001). The number of ACPA reactivities was related to PF development, both in crude and adjusted models (p<0.05 for both). In models concomitantly adjusted for the three SNPs (rs35705950, rs111521887 and rs2609255) respectively, in addition to mentioned adjustments the number of ACPA reactivities (p<0.05 for all three nmodels), Vim60-75 (p<0.05, in all three models), Fibβ62–78 (72) (p<0.001-p<0.05) and F4-CIT-R (p<0.01-p<0.05) were all found significantly associated to PF development irrespective of the SNPs.ConclusionThe development of PF in an inception cohort of RA patients was associated both with risk genes and, independently of the risk genes, the presence of certain ACPA, and the number of ACPA reactivities.References[1]Jönsson E, et al.

- Ankylosing spondylitis (AS) is associated with an elevated risk of cardiovascular disease (CVD) related to atherosclerosis, preceded by arterial stiffness. We aimed to examine common carotid artery (CCA) biomechanical properties using ultrasound to calculate β stiffness index (indicating arterial stiffness) and, a more recently developed technique, 2-dimensional (2D) speckle tracking strain (indicating arterial motion and deformation, strain) to (1) compare with age- and sex-matched controls, and (2) analyze relationships between strain and stiffness with disease characteristics and traditional risk factors for CVD in patients with AS.Methods.In this cross-sectional study, a cohort of 149 patients with AS, mean age 55.3 ± 11.2 years, 102 (68.5%) men, and 146 (98%) HLA-B27–positive, were examined. Bilateral CCA were examined for circumferential 2D strain and β stiffness index. A subgroup of 46 patients was compared with 46 age- and sex-matched controls, both groups without hypertensive disease, diabetes, myocardial infarction, or stroke.Results.Mean bilateral circumferential 2D strain was lower in AS patients compared with controls (7.9 ± 2.6% vs 10.3 ± 1.9%, P < 0.001), whereas mean bilateral β stiffness index was higher (13.1 ± 1.7 mmHg/mm vs 12.3 ± 1.3 mmHg/mm, P = 0.02). In multivariable linear regression analyses, strain was associated with age, erythrocyte sedimentation rate, history of anterior uveitis, and treatment with conventional synthetic disease-modifying antirheumatic drugs (DMARD) and/or biological DMARD (R2 0.33), while stiffness was associated with age (R2 0.19).Conclusion.Both CCA circumferential 2D strain and β stiffness index differed between patients with AS and controls. Strain was associated with AS-related factors and age, whereas only age was associated with stiffness, suggesting that the obtained results reflect different pathogenic vascular processes.

Tidskriftsartikel (refereegranskat)abstract
- Black carbon (BC), spheroidal carbonaceous particles (SCP), and polycyclic aromatic hydrocarbons (PAH) are carbonaceous pollutants affecting the climate, environment, and human health. International regulations limit their emissions, and the present emissions are followed by monitoring programs. However, the monitoring programs have limited spatio-temporal coverage and only span the last decades. We can extend the knowledge of historical emission rates by measuring pollution levels in radiometrically dated marine and lacustrine sediment sequences. Here we present measurements of BC, SCP, and PAH from a sediment sequence sampled in the Öresund strait, between Denmark and Sweden and dated back to CE 1850. Our data show a massive increase in the burial rates of all measured pollutants starting in the 1940s. The pollution deposition peaked in the 1970-1980s and declined through the 1990s. However, the declining trend was reversed in the 2000s. Source appointment of PAHs shows a relatively higher contribution of emissions from wood-burning since CE 2000. This coincides with a change towards the increased use of biomass for both municipal and regional energy production in Scandinavia. Our results demonstrate that changes in energy production have caused changes in the delivery of carbonaceous pollution to marine environments. The increase in particle emissions from wood burning is potentially posing a future environmental and health risk.

- Rheumatoid arthritis (RA) patients have a reduced life expectancy, with cardiovascular disease (CVD) being the most frequent cause of death. The mechanisms behind the increased CVD morbidity and mortality in RA are not fully understood. Systemic inflammation is an important contributor to the accelerated arteriosclerosis in RA, and traditional risk factors for CVD are usually more prevalent in RA patients than in the general population. How much the current state of RA disease control impacts the short-term risk of CVD events remains unclear.ObjectivesTo estimate the short-term risks and relative risks of acute coronary syndrome (ACS) in patients with RA as a function of RA disease activity, with particular focus on remission.MethodsWe identified patients with RA from the clinical rheumatology registers (CRR) in Sweden (SE) and Norway (NO), and for these patients we retrieved all registered clinical rheumatology visits from January 1st, 2012 to December 31st, 2020. At each visit, we assessed whether the patient was in remission or not according to multiple definitions including DAS28, ACR criteria, and SDAI. We also categorised the disease activity at each visit into categories (remission, low, moderate and high) using DAS28-ESR. Patients had to be free of any history of ACS in a five-year look back window (assessed at the visit date), and were followed for 6 months from each visit date until ACS event (defined as hospitalization due to ACS or death due to either ACS or sudden death) or censoring (death due to other causes, migration, end of the study). We compared the risk of ACS between patients who were (vs. were not) in remission using Cox regression with robust standard errors (accounting for the correlated data structure), adjusted for covariates (including age at the visit, sex, number of previous treatment courses, use of prednisolone, the expanded risk score in RA (ERS-RA), and defined co-morbidities: diabetes, malignancy, respiratory failure, liver failure and kidney disease) and stratified by country.ResultsWe included 43,338 RA patients and their 223,197 visits (211,158 (SE), 12,039 (NO)). 74% of the visits were from women, with a mean age (SD) at visit of 62 (14) years. Several clinical characteristics including treatments and comorbidity history varied with disease activity (Table 1). By contrast, age, number of previous DMARDs, disease duration and smoking habits were relatively similar across categories of disease activity (Table 1).Table 1.Median [Q1-Q3] or percentage for clinical characteristics in remission (DAS28-ESR<=2.6) and high disease activity (DAS28-ESR>5.1) categoriesVariableRemissionHigh disease activityN (visits)91,49725,364Age, years65[53-72]63[53-72]Disease duration10[4-18]8[2-17]N treatment courses0[0-0]0[0-1]Prednisolon28%58%Tender joint count, 28-joints (TJC)0[0-0]10[6-14]Swollen joint count, 28-joints (SJC)0[0-0]7[4-10]Erythrocyte sedimentation rate, ESR10[6-18]28[15-47]C-reactive protein (CRP)3[1-4]14[5-32]Patient global assessment, PGA13[4-27]70[55-82]Pain12[4-27]70[55-82]ERS-RA8[3-16]12[5-23]Ischemic heart disease6%7%Diabetes9%13%Hypertension39%42%Hyperlipidemia23%25%Ever smoking45%50%We observed 598 ACS events (in 554 patients) during the 6-month follow-up window. Comparing patients not in remission to patients in remission, adjusting for the covariates described above, indicated that not being in remission increased the risk of ACS occurrence (Figure 1). Similarly, there was an association between DAS28-ESR at the visit and the risk of ACS during the coming six months.Figure 1.Hazard ratio (95% confidence interval) comparing patients not in remission to patients in remission, using several remission definitions. Percentage of visits with an ACS event within 6 months (bottom panel).ConclusionBeing in RA remission at any visit is associated with a noticeably lower risk of ACS during the following months, suggesting that RA disease activity not only affects CVD risk in the longer term but also in the short term.AcknowledgementsNordForsk and Foreum partially funded this research project.Disclosure of InterestsBénédicte Delcoigne: None declared, Sella Aarrestad Provan: None declared, Eirik kristianslund: None declared, Johan Askling Grant/research support from: AbbVie, AstraZeneca, Bristol Myers Squibb, Eli Lilly, Janssen, Merck, Pfizer, Roche, Samsung Bioepis, Sanofi, and UCB, Lotta Ljung: None declared.
