- OBJECTIVE: To assess mortality related to musculoskeletal (MSK) disorders and rheumatoid arthritis (RA), specifically, among adults (aged ≥ 20 yrs) in southern Sweden using the multiple-cause-of-death approach.METHODS: All death certificates (DC; n = 201,488) from 1998 to 2014 for adults in the region of Skåne were analyzed when mortality from MSK disorders and RA was listed as the underlying and nonunderlying cause of death (UCD/NUCD). Trends in age-standardized mortality rates (ASMR) were evaluated using joinpoint regression, and associated causes were identified by age- and sex-adjusted observed/expected ratios.RESULTS: MSK (RA) was mentioned on 2.8% (0.8%) of all DC and selected as UCD in 0.6% (0.2%), with higher values among women. Proportion of MSK disorder deaths from all deaths increased from 2.7% in 1998 to 3.1% in 2014, and declined from 0.9% to 0.5% for RA. The mean age at death was higher in DC with mention of MSK/RA than in DC without. The mean ASMR for MSK (RA) was 15.5 (4.3) per 100,000 person-years and declined by 1.1% (3.8%) per year during 1998-2014. When MSK/RA were UCD, pneumonia and heart failure were the main NUCD. When MSK/RA were NUCD, the leading UCD were ischemic heart disease and neoplasms. The greatest observed/expected ratios were seen for infectious diseases (including sepsis) and blood diseases.CONCLUSION: We observed significant reduction in MSK and RA mortality rates and increase in the mean age at death. Further analyses are required to investigate determinants of these improvements in MSK/RA survival and their potential effect on the Swedish healthcare systems.

- To investigate muscle impairment (isometric and dynamic) and disease activity during the first year after diagnosis of polymyositis (PM) and dermatomyositis (DM), and to study the relationship between muscle impairment, patient-reported health, and disease activity.Methods.Seventy-two patients enrolled in the Swedish Myositis Register, 2003–2010, were followed prospectively. The Manual Muscle test (MMT-8; isometric muscle strength), the Functional Index of myositis test (FI-2; dynamic, repetitive muscle function), and disease activity (6-item core set) were retrieved at the time of diagnosis, and after 6 and 12 months. Self-reported health (Medical Outcomes Study Short Form-36; SF-36) was retrieved at 12 months.Results.At the time of diagnosis, median (Q1–Q3) for the FI-2 was 27.2% (7.9–60.5%) of maximal score compared to 93.8% (92.5–98.8%) of maximal MMT-8. At 12 months, the FI-2 and the MMT-8 improved to 29.4% (16.5–60.7%; p < 0.05) and 96.1% (88.1–99.4%), respectively (p < 0.01). At 12 months, 45% of patients improved ≥ 20%, and 27% worsened ≥ 20% in FI-2 score, while 10% improved ≥ 20% in MMT-8. Physician’s global visual analog scale (VAS), Health Assessment Questionnaire, and creatine phosphokinase levels improved significantly at 12 months (p < 0.05–0.001) while patient’s global and extramuscular VAS remained unchanged. The SF-36 physical function correlated strongly with the FI-2 (rs = 0.74; CI 0.55–0.85) and moderately with the MMT (rs = 0.54; CI 0.27–0.73), with lower correlations between muscle function and other SF-36 domains.Conclusion.Patients with PM/DM were characterized by impaired dynamic repetitive muscle function (DRMF) that correlated well with patient-reported physical function. Assessment of DRMF adds information regarding muscle impairment in these patients.

- Objective. To compare outcomes over the first 8 years in patients with early rheumatoid arthritis (RA) recruited in the 1990s and the 2000s, with a special focus on functional disability and its possible predictors. Methods. Data were acquired from 1938 patients with early RA (American College of Rheumatology 1987 criteria) included in the BARFOT study, who had completed the 8-year followup. The patients were divided into 2 cohorts: cohort 1 (n = 928, 68% women) included from 1992 to 1999 and cohort 2 (n = 1010, 70% women) included from 2000 to 2006. Health Assessment Questionnaire (HAQ), 28-joint Disease Activity Score (DAS28), visual analog scale pain, and radiographs of hands and feet scored by the van der Heijde modified Sharp method were assessed during the 8 years. Longitudinal data analyses were performed using a generalized linear model. Results. Despite more active medical treatment during the 2000s, the courses of HAQ and pain showed no difference between the cohorts during followup, in either women or in men, with significantly higher levels in women compared with men. However, as expected, disease activity decreased more over time in cohort 2 compared with cohort 1, for both sexes, and women in cohort 2 had less radiographic progression compared with cohort 1. HAQ was associated with DAS28, pain, radiological scores, and sex in both cohorts, and in cohort 2 also with age and smoking. Conclusion. Patients included in the 2000s had lower disease activity, but not less activity limitation and pain over 8 years of followup despite more active treatment. Pain, aging, and smoking might explain why patients included in the 2000s still had the same disability levels as those included in the 1990s.

- Indicators of work role functioning (being at work, and being productive while at work) are important outcomes for persons with arthritis. As the worker productivity working group at OMERACT (Outcome Measures in Rheumatology), we sought to provide an evidence base for consensus on standardized instruments to measure worker productivity [both absenteeism and at-work productivity (presenteeism) as well as critical contextual factors].

- Several aspects of rituximab (RTX) retreatment in rheumatoid arthritis (RA) need to be further elucidated. The aim of this study was to describe the effect of repeated courses of RTX on disease activity and to compare 2 retreatment strategies, fixed-interval versus on-flare retreatment, in a large international, observational, collaborative study.Methods.In the first analysis, patients with RA who received at least 4 cycles with RTX were included. In the second analysis, patients who received at least 1 RTX retreatment and for whom information about the strategy for retreatment was available were identified. Two retreatment strategies (fixed-interval vs on-flare) were compared by fitting-adjusted, mixed-effects models of 28-joint Disease Activity Score (DAS28) over time for first and second retreatment.Results.A total of 1530 patients met the eligibility criteria for the first analysis. Significant reductions of mean DAS28 between the starts of subsequent treatment cycles were observed (at start of first treatment cycle: 5.5; second: 4.3; third: 3.8; and fourth: 3.5), suggesting improved response after each additional cycle (p < 0.0001 for all pairwise comparisons). A total of 800 patients qualified for the second analysis: 616 were retreated on flare and 184 at fixed interval. For the first retreatment, the fixed-interval retreatment group yielded significantly better results than the on-flare group (estimated marginal mean DAS28 = 3.8, 95% CI 3.6–4.1 vs 4.6, 95% CI 4.5–4.7, p < 0.0001). Similar results were found for the second retreatment.Conclusion.Repeated treatment with RTX leads to further clinical improvement after the first course of RTX. A fixed-interval retreatment strategy seems to be more effective than on-flare retreatment.

- Rheumatoid arthritis (RA) that is negative for anticitrullinated protein antibodies (ACPA) is a subentity of RA, characterized by less severe disease. At the individual level, however, considerable differences in the severity of joint destruction occur. We performed a study on genetic factors underlying the differences in joint destruction in ACPA-negative patients.

- It was with great interest that we read the letter from Watson and colleagues1 describing their investigation of how a primary care diagnosis of gout compares to a primary care diagnostic rule for gout and the 1977 American Rheumatism Association (ARA) classification criteria of acute arthritis of primary gout. They present positive predictive values (PPV) of 74% for the diagnostic rule and 80% for the ARA criteria.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: It has been proposed that remission should be maintained throughout the course of rheumatoid arthritis (RA); however, the evidence supporting this is limited. Physical function measured by the Health Assessment Questionnaire (HAQ) is a major outcome in RA, and HAQ is shown to be one of the strongest predictors of longterm outcomes. The purpose of this study was to investigate the physical function over a long time in patients with RA who achieved sustained remission (SR) compared with that of patients occasionally achieving remission [non-sustained remission (NSR)].METHODS: Patients with RA treated with antitumor necrosis factor and included in the South Swedish Arthritis Treatment Group register were eligible for this study. We identified patients with a Disease Activity Score at 28 joints (DAS28) < 2.6 or Simplified Disease Activity Index (SDAI) ≤ 3.3 at some point and those who achieved SR, i.e., remission during consecutive visits for at least 6 months. The course of functional status was assessed using the HAQ at each visit.RESULTS: Of the 2416 patients, 1177 (48.7%) reached DAS28 remission at some point. SR was achieved by 382 (15.8%) for the DAS28 and 186 (7.7%) for the SDAI criteria. Comparing the SR and NSR groups, HAQ improved during the first 12 months in the DAS28 remission. HAQ continued to improve relatively as long as SR was maintained. A higher proportion of patients in SR reached full physical function.CONCLUSION: In patients with established RA, physical function measured by the HAQ improves in patients reaching SR compared with patients who only occasionally reach remission. The improvement continues while in remission, which supports that maintaining remission should be a treatment goal.
