- Objective There is a lack of standardisation in the terminology used to describe gout. The aim of this project was to develop a consensus statement describing the recommended nomenclature for disease states of gout. Methods A content analysis of gout-related articles from rheumatology and general internal medicine journals published over a 5-year period identified potential disease states and the labels commonly assigned to them. Based on these findings, experts in gout were invited to participate in a Delphi exercise and face-to-face consensus meeting to reach agreement on disease state labels and definitions. Results The content analysis identified 13 unique disease states and a total of 63 unique labels. The Delphi exercise (n=76 respondents) and face-to-face meeting (n=35 attendees) established consensus agreement for eight disease state labels and definitions. The agreed labels were as follows: 'asymptomatic hyperuricaemia', 'asymptomatic monosodium urate crystal deposition', 'asymptomatic hyperuricaemia with monosodium urate crystal deposition', 'gout', 'tophaceous gout', 'erosive gout', 'first gout flare' and 'recurrent gout flares'. There was consensus agreement that the label 'gout' should be restricted to current or prior clinically evident disease caused by monosodium urate crystal deposition (gout flare, chronic gouty arthritis or subcutaneous tophus). Conclusion Consensus agreement has been established for the labels and definitions of eight gout disease states, including 'gout' itself. The Gout, Hyperuricaemia and Crystal-Associated Disease Network recommends the use of these labels when describing disease states of gout in research and clinical practice.

- Objective The language currently used to describe gout lacks standardization. The aim of this project was to develop a consensus statement on the labels and definitions used to describe the basic disease elements of gout. Methods Experts in gout (n = 130) were invited to participate in a Delphi exercise and face-to-face consensus meeting to reach consensus on the labeling and definitions for the basic disease elements of gout. Disease elements and labels in current use were derived from a content analysis of the contemporary medical literature, and the results of this analysis were used for item selection in the Delphi exercise and face-to-face consensus meeting. Results There were 51 respondents to the Delphi exercise and 30 attendees at the face-to-face meeting. Consensus agreement (>= 80%) was achieved for the labels of 8 disease elements through the Delphi exercise; the remaining 3 labels reached consensus agreement through the face-to-face consensus meeting. The agreed labels were monosodium urate crystals, urate, hyperuric(a)emia, tophus, subcutaneous tophus, gout flare, intercritical gout, chronic gouty arthritis, imaging evidence of monosodium urate crystal deposition, gouty bone erosion, and podagra. Participants at the face-to-face meeting achieved consensus agreement for the definitions of all 11 elements and a recommendation that the label "chronic gout" should not be used. Conclusion Consensus agreement was achieved for the labels and definitions of 11 elements representing the fundamental components of gout etiology, pathophysiology, and clinical presentation. The Gout, Hyperuricemia, and Crystal-Associated Disease Network recommends the use of these labels when describing the basic disease elements of gout.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To describe electrocardiographic (ECG) development in patients with ankylosing spondylitis (AS) and identify associations between baseline characteristics and cardiac conduction disturbances (CCD) at 5-year follow-up.Methods: In a longitudinal cohort study, 172 patients (54% men, mean age (SD) of 50 (13) years at baseline) with AS underwent ECG, physical examination, questionnaires and laboratory testing at baseline and at 5-year follow-up. Descriptive statistics and univariate and age- and sex-adjusted logistic regression analyses were used. CCD included both atrioventricular and intraventricular blocks.Results: Twenty-three of the 172 patients (13.4%) had a CCD at follow-up. Eight patients had developed a new CCD and eight had normalised their ECG. In the age- and sex-adjusted analyses, CCD at baseline (OR 24.8, 95% CI 7.3 to 84.5), male sex (OR 6.4, 95% CI 2.0 to 20.8), history of anterior uveitis (OR 4.4, 95% CI 1.3 to 14.5), higher ASDAS-CRP (OR 2.3, 95% CI 1.3 to 4.0), greater waist circumference (OR 1.3, 95% CI 1.1 to 1.6, per 5 cm), and medication with antiplatelets (OR 7.0, 95% CI 1.5 to 31.8) and beta-blockers (OR 3.4, 95% CI 1.0 to 11.5) were associated with a CCD at follow-up. Higher age and longer symptom duration were highly correlated and were both associated with a CCD at follow-up.Conclusions: The presence of CCD in AS is in part dynamic and associated with both AS and non-AS characteristics. Our results suggest that patients especially prone to present with CCDs are older men with a previous CCD, longer symptom duration, higher AS disease activity, a history of anterior uveitis and medication reflecting cardiovascular disease.

- BackgroundObesity is over-represented in patients with psoriatic arthritis (PsA) and associated with higher disease activity, poorer effect of treatment and increased cardiovascular morbidity. Studies on the effects of weight loss are however needed. This study aimed to prospectively study the effects of weight loss treatment with very low energy diet (VLED) on disease activity in patients with PsA (CASPAR criteria) and obesity (body mass index BMI 33kg/m(2)).MethodsVLED (640kcal/day) was taken during 12-16weeks, depending on pre-treatment BMI. Afterwards, an energy-restricted diet was gradually reintroduced. Weight loss treatment was given within a structured framework for support and medical follow-up.Treatment with conventional synthetic and/or biologic disease-modifying anti-rheumatic drugs was held constant from 3months before, until 6months after baseline.Patients were assessed with BMI, 66/68 joints count, Leeds enthesitis index, psoriasis body surface area (BSA), questionnaires and CRP at baseline, 3 and 6months. Primary outcome was the percentage of patients reaching minimal disease activity (MDA) and secondary outcomes were reaching Psoriatic Arthritis Response Criteria (PsARC) and American College of Rheumatology (ACR) response criteria.ResultsTotally 41/46 patients completed the study, 63% women, median age 54years (IQR 48-62). At baseline increased BMI was associated with higher disease activity and poorer function.The median weight loss was 18.7kg (IQR 14.6-26.5) or 18.6% (IQR 14.7-26.3) of the baseline weight. A majority of the disease activity parameters improved significantly after weight loss, including 68/66 tender/swollen joints count, CRP, BSA, Leeds enthesitis index, HAQ and patient VAS for global health, pain and fatigue. A larger weight loss resulted in more improvement in a dose-response manner. The percentage of patients with MDA increased from 29 to 54%, (p=0.002). PsARC was reached by 46.3%. The ACR 20, 50 and 70 responses were 51.2%, 34.1% and 7.3% respectively.ConclusionsShort-term weight loss treatment with VLED was associated with significant positive effects on disease activity in joints, entheses and skin in patients with PsA and obesity. The study supports the hypothesis of obesity as a promotor of disease activity in PsA.Trial registrationClinicalTrials.gov identifier: NCT02917434, registered on September 21, 2016retrospectively registered

- Introduction: Low serum urate (sU) has been suggested to increase the risk of dementia since a reduction might impair antioxidant capacity. On the other hand, high sU is associated with increased cardiovascular risk which might increase the risk of dementia, especially for vascular dementia. Methods: In 1968-1969, a population-based sample of 1462 women aged 38 to 60 years was examined and were followed up over 44 years (mean 33.1 years). We examined whether sU (determined in 1968-1969 and 1992-1994) is associated with risk of late-life dementia. Results: During 44 years of follow-up, a higher sU (per standard deviation of 76.5 mu mol/L) was associated with lower risk for dementia (n = 320; hazard ratio [HR] 0.81; confidence interval [CI] 0.72-0.91), Alzheimer's disease (n = 152; HR 0.78; CI 0.66-0.91), and vascular dementia (n = 52; HR 0.66; CI 0.47-0.94). Discussion: Our findings support the hypothesis that sU has a protective role in the development of dementia, regardless of dementia subtype. This may have important implications in the treatment of dementia and treatment goals for hyperuricemia in patients with gout. (C) 2019 the Alzheimer's Association. Published by Elsevier Inc.

- Introduction: A recent survey showed that 27% of rheumatoid arthritis (RA) patients had inadequately controlled disease activity. Hence, there is a need for new strategies aiming at improving patient outcomes. The aim of the present study was to evaluate the effect of a nurse-led clinic with frequent visits, treat-to-target and person-centred care of patients with established RA and moderate-to-high disease activity compared with patients receiving regular care. Methods: The study was a randomized, controlled trial over 26weeks, with a nonrandomized extension to week 50. Patients were randomized to an intervention group (IG; nurse-led clinic) based on person-centred care, frequent visits and “treat to target”, or to a control group (CG) which visited the clinic according to care as usual. The primary outcome was the difference in the DAS28 change between the IG and the CG groups. Results: A total of 332 patients were screened for eligibility, of which 70 were randomly assigned to either the IG (n=36) or the CG (n=34) group. The primary outcome was not met, although patients in the IG group tended to improve more than those in the CG group (difference: 0.43 (95% confidence interval [CI] –0.27, 1.13). In both the IG and CG groups, delta-DAS28 improved significantly. The European League Against Rheumatology moderate or good response was achieved by 76% (95% CI 58, 89) in the IG and 49% (95% CI 32, 65) in the CG group. Conclusions: Disease activity tended to improve more with the nurse-led intervention compared with regular care, although the difference was not significant, probably partly due to the lack of statistical power. © 2019 The Authors Musculoskeletal Care published by John Wiley & Sons Ltd

- Objective: To estimate the prevalence and incidence of non-gout crystal arthropathy in relation to socioeconomic factors in southern Sweden. Methods: All patients (age >= 18 years) with at least one visit to a physician with the diagnosis of interest in the Skane region (population of 1.3 million) in 1998-2014 were identified. Non-gout crystal arthropathy (ICD-10 codes M11.0-M11.9) was subclassified in four different groups: calcium pyrophosphate crystal deposition related arthropathy (CPPD), unspecified non-gout arthropathies, chondrocalcinosis, and hydroxyapatite crystal deposition disease. The crude and age-adjusted point prevalence on December 31, 2014, and the cumulative incidence during 2014 were calculated for all non-gout crystal arthropathies, CPPD, and other unspecified non-gout arthropathies overall and in relation to occupation, income, and level of education. Results: The crude 2014 point prevalence (95% CI) and 2014 cumulative incidence (95% CI) of all non-gout crystal arthropathies were 0.23% (0.23-0.24) and 21.5 (19-25) cases/100,000 persons. Mean age (range) among all prevalent cases in 2014 was 71 (20-102) years and 56% were males. The point prevalence and cumulative incidence of CPPD were 0.09% (0.08-0.09) and 8 (7-10)/100,000 persons, respectively. The corresponding data for unspecified non-gout crystal deposition disease was 0.16% (0.16-0.17) and 15.6 (13-18)/100,000 persons, respectively. The prevalence and incidence of CPPD and unspecified non-gout crystal arthropathies were slightly higher in men and increased with age irrespective of gender. Unspecified non-gout crystal arthropathy but not CPPD was less prevalent in persons with >= 15 years of education, whereas there were no clear associations with occupation and income. Conclusion: The prevalence of all diagnosed non-gout crystal arthropathies was 0.23%, thus considerably less prevalent than gout in southern Sweden. CPPD and other unspecified non-gout crystal arthropathies are the predominant diagnoses, increasing with age and in men. With the exception for unspecified non-gout crystal arthropathies being inversely correlated to a higher level of education, no convincing association with the socioeconomic factors was found.

Tidskriftsartikel (refereegranskat)abstract
- Objective Although clinical trials support equivalence of originator products and biosimilars for etanercept and infliximab, real-world studies among biologics-naive patients with spondyloarthritis (SpA) are lacking. The objectives were to compare treatment retention in biologics-naive patients with SpA starting either the originator product or a biosimilar of infliximab and etanercept, and to explore the baseline characteristics of these patients. Methods Patients with SpA (ankylosing spondylitis/non-radiographical axial SpA/undifferentiated SpA), starting infliximab or etanercept as their first-ever biological disease-modifying antirheumatic drug during January 2014-June 2017 were identified in five Nordic biologics-rheumatology registers. Baseline characteristics were retrieved from each registry; comorbidity data were identified through linkage to national health registers. Country-specific data were pooled, and data on infliximab and etanercept were analysed separately. Comparisons of treatment retention between originators and biosimilars were assessed through survival probability curves, retention rates (2 years for infliximab/1 year for etanercept) and Hazard Ratios (HR). Results We included 1319 patients starting infliximab (24% originator/76% biosimilar), and 1015 patients starting etanercept (49% originator/51% biosimilar). Baseline characteristics were largely similar for the patients treated with the originators compared with the corresponding biosimilars. Survival probability curves were highly similar for the originator and its biosimilar, as were retention rates: infliximab 2-year retention originator, 44% (95% CI 38% to 50%)/biosimilar, 46% (95% CI: 42% to 51%); and etanercept 1-year retention originator, 66% (95% CI 61% to 70%)/biosimilar, 73% (95% CI 68% to 78%). HRs were not statistically significant. Conclusion This observational study of biologics-naive patients with SpA from five Nordic countries showed similar baseline characteristics and very similar retention rates in patients treated with originators versus biosimilars, for both infliximab and etanercept, indicating comparable effectiveness in clinical practice.

- Several studies have shown a negative association between smoking and primary Sjogren's syndrome (pSS), and smoking may interfere with the immune response. The purpose of this study was to investigate if smoking affects disease activity and disease phenotype in pSS. In this cross-sectional study, consecutive pSS patients filled out the EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) form and a structured questionnaire regarding smoking habits. EULAR Sjogren's Syndrome Disease Activity Index (ESSDAI) scores were calculated and blood samples were analysed for type I interferon signature using RT-PCR. Of 90 patients (93% women, median age 66.5 years), 72% were type I IFN signature positive and 6, 42 and 53% were current, former and never smokers, respectively. No significant differences by smoking status were found regarding ESSDAI total score, activity in the ESSDAI domains or type I IFN signature. Patients with a higher cumulative cigarette consumption (>= median) had higher scores in ESSPRI total [5.0 (3.0-6.3) vs 8.0 (6.0-8.3); p < 0.01] and ESSPRI sicca and pain domains. Comparing type I IFN signature negative and positive patients, the latter had significantly lower activity in ESSDAI articular domain (7/25 vs 3/64; p < 0.01) and lower scores in ESSPRI total [7.7 (5.2-8.2) vs 6.0 (4.0-7.7); p = 0.04]. Smoking was not associated with disease phenotype although patients with a higher cumulative cigarette consumption had worse symptoms in some disease domains. Current smokers were few making it difficult to draw any firm conclusions about associations to current smoking.
