- Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996-1998 and 463 patients were included in the second cohort (TIRA-2) during 2006-2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

- Objectives: To determine socioeconomic inequalities in frequent knee pain (FKP), knee osteoarthritis (OA), and associated health-related quality of life (HRQoL) in Sweden. Method: In 2007 a postal questionnaire about knee pain was sent to a random sample of 10 000 residents of Malmö, Sweden (7402 individuals responded). Subjects reporting pain with duration ≥ 4 weeks in one or both knees in the past 12 months were classified as having FKP. A random sample of 1527 subjects with and without FKP attended a clinical and radiographic knee examination and responded to generic and disease-specific HRQoL questionnaires. We used the individuals’ level of education and occupation as socioeconomic status (SES) measures, and we calculated the relative index of inequality (RII) using Poisson regression with robust standard errors adjusted for age and gender. We applied weighting to account for a possible selection bias that might arise from non-responses in the study. Results: With education, the RIIs for FKP and knee OA were 0.71 [95% confidence interval (CI) 0.61–0.84] and 0.56 (95% CI 0.34–0.93), respectively. With occupation, the corresponding figures were 0.70 (95% CI 0.60–0.82) and 0.59 (95% CI 0.37–0.94), respectively. There were socioeconomic gradients in HRQoL in favour of people with better SES. RIIs for FKP and HRQoL but not knee OA were essentially similar after additional adjustment for mediators. Conclusions: In Sweden there are socioeconomic gradients related to both FKP and knee OA as well as HRQoL in favour of people with better SES. SES should be taken into account in health resource allocation pertaining to knee-related disorders.

- To test the hypothesis that non-HLA single-nucleotide polymorphisms (SNPs) associated with the risk of juvenile idiopathic arthritis (JIA) are risk factors for an unfavourable disease outcome at long-term follow-up.The Nordic JIA cohort is a prospective multicentre study cohort of patients from the Nordic countries. In all, 193 patients met the inclusion criteria of having an 8year follow-up assessment and available DNA sample. Seventeen SNPs met the inclusion criteria of having significant associations with JIA in at least two previous independent study cohorts. Clinical endpoints were disease remission, actively inflamed joints and joints with limitation of motion (LOM), articular or extra-articular damage, and history of uveitis.Evidence of associations between genotypes and endpoints were found for STAT4, ADAD1-IL2-IL21, PTPN2, and VTCN1 (p=0.003-0.05). STAT4_rs7574865 TT was associated with the presence of actively inflamed joints [odds ratio (OR) 20.6, 95% confidence interval (CI) 2.2->100, p=0.003] and extra-articular damage (OR 7.9, 95% CI 1-56.6, p=0.057). ADAD1_rs17388568 AA was associated with a lower risk of having joints with LOM (OR 0.1, 95% CI 0-0.55, p=0.016). PTPN2_rs1893217 CC was associated with a lower risk of having joints with LOM (OR 0.2, 95% CI 0-0.99, p=0.026), while VTCN1_rs2358820 GA was associated with uveitis (OR 3.5, 95% CI 1-12.1, p=0.029).This exploratory study, using a prospectively followed JIA cohort, found significant associations between long-term outcome and SNPs, all previously associated with development of JIA and involved in immune regulation and signal transduction in immune cells.

- Objectives: To determine the health-related quality of life (HRQOL) and its relationship to disease variables, vertebral fractures, and employment status in female patients with systemic lupus erythematosus (SLE). Methods: HRQOL was assessed with the Swedish version of the Medical Outcomes Study (MOS) 36-Item Short Form Survey (SF-36) in female patients (n=163) and in age- and sex-matched controls (n=1045). Associations between the SF-36 score and demographics, disease variables, prevalent vertebral fractures, and employment status were analysed. Results: The SLE patients, aged 20 to 82 years, scored significantly lower than the controls on all SF-36 subscales. Patients with vertebral fractures were older, had greater disease damage, and lower physical functioning (PF) than patients without fractures. Of the SLE patients of working age (n=142), 54% worked full or part time. These patients scored their HRQOL significantly higher (better) than patients not working. Being able to work was significantly associated with low age and high scores in PF and role physical (RP): the area under the receiver operating characteristic (ROC) curve for these variables was 0.82, confidence interval 0.75-0.89. Conclusions: HRQOL is substantially lower in SLE than in the general population but working ability indicates better health. We encourage further research regarding the effects on HRQOL by preventive actions taken against work disability in SLE.

- Increased serum levels of hyaluronan (HA) have been found in patients with liver diseases, psoriasis, malignancies as well as in rheumatoid arthritis and osteoarthritis. In the two latter groups serum HA levels may reflect the extent of synovial involvement and inflammation, rather than only unspecific information. This study was performed to elucidate the value of measuring HA in children with juvenile chronic arthritis (JCA) and to study its relation to class specific rheumatoid factors (IgM Rf and IgA Rf). HA was analysed in sera from 271 patients with JCA and 130 controls using a radiometric assay and IgM Rf and IgA Rf were analysed using an enzyme immunoassay. The results were analysed in relation to JCA subgroup, disease activity and functional outcome. In patients and controls higher levels of HA were found in young children than in older. Raised levels of HA and IgM Rf were mainly found in children with polyarticular disease. Impaired functional outcome was related to raised HA levels. No correlation was found between HA levels and IgM Rf or IgA Rf. Measurement of HA levels in JCA is of no diagnostic value because of low sensitivity. Quantification of HA may, however, have prognostic value in a subgroup of patients belonging to the polyarticular subgroup.

- The relation between reported chronic pain and clinical findings was studied by comparing survey data six months before and eighteen months after a clinical examination. Studied individuals (n = 165) were randomly selected from subsamples of an initial survey (n = 1806) to a general population. Among individuals reporting chronic pain 85% were assessed to have chronic pain at the examination. Diagnoses were found in 22% of examined pain individuals. Myofascial pain syndrome and myalgia were the most common findings. Compared with located neck-shoulder pain, widespread pain had a greater impact on the individual, a worse prognosis regarding pain duration and working capacity, and revealed a raised serum urate level of unclear significance. Although no specific cause of pain is found in individuals with widespread pain it is important to identify and treat this group due to the great effects on functional capacity and the worse prognosis.

- OBJECTIVE: To study the relationship between reported chronic pain and the level of serum urate (SU) among women with various diagnoses of the musculoskeletal system. METHODS: Consecutive female patients (aged 20-70 years, n = 124), at rheumatology and rehabilitation practices, with chronic musculoskeletal pain of different origins were followed for 1 year after an initial survey of pain, lifestyle, quality of life, and disability. Repeated blood samples (including urate, creatinine, cholesterol, and glucose) were analysed. Multiple regression analysis was performed to explain initial variations in SU level in relation to pain and confounding factors. RESULTS: The level of SU was increased among individuals with widespread pain (>5 locations) independent of underlying diagnoses compared to those with fewer pain sites (270.5 vs. 241.2 micromol/L). Serum creatinine, body mass index (BMI), the number of pain locations, and sleep disturbances independently contributed to the SU level and explained 43% of the variation in SU. Individual variation in SU during 4 months was low. CONCLUSIONS: Epidemiological data on the relationship between the extent of body pain and SU were confirmed in a clinical setting. Besides known factors such as impaired renal function and obesity, widespread pain and sleep disturbances were related to an increase in SU. Medication and alcohol intake could not explain the findings. Longitudinal studies are necessary to elucidate whether the level of SU has any implications for the prognosis of chronic pain.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To study transitions from and to chronic widespread pain (CWP) over 7 years in patients with rheumatoid arthritis (RA). Method: Two postal questionnaires were sent to patients included in the BARFOT (Better Anti-Rheumatic Pharmacotherapy) study, the first in 2010 and the second in 2017. The questionnaires assessed pain, number of tender and swollen joints, functional disability, health-related quality of life (HRQoL), pharmacological treatment, lifestyle factors, and patient-reported body mass index (BMI). The responders to both questionnaires were divided into three groups according to the reported pain duration and distribution: patients having no chronic pain (NCP), chronic regional pain (CRP), and CWP. Results: In all, 953 patients answered the questionnaires at both time-points. One-third (324) of the patients reported CWP in 2010, and 140 (43%) of the patients had transition to NCP or CRP in 2017. In multivariate logistic regression models, adjusting for age, gender, and disease duration, transition from CWP was associated with normal BMI, fewer tender joints, less pain, less fatigue, fewer pain regions, less disability, better HRQoL, and biologic treatment. In 2010, 628 patients reported NCP or CRP, whereas 114 of them reported CWP in 2017. Transition to CWP was associated with female gender, obesity, more tender and swollen joints, higher pain-related variables, worse disability, and worse HRQoL. Conclusion: There are modifiable factors associated with transitions from and to CWP that could be identified. Paying attention to these factors could improve pain treatment in the management of RA.

Tidskriftsartikel (refereegranskat)abstract
- Objective Patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) require immunosuppressive therapy for disease control and relapse prevention and may be at risk for severe coronavirus disease 2019 (COVID-19). The study objective was to analyse risk factors and outcomes of COVID-19 in well-characterized AAV patients. Method Data were retrieved from March 2020 to May 2021 from medical records of AAV cohorts in Stockholm and Uppsala, Sweden. COVID-19 was confirmed by positive PCR test or by ELISA. Severe COVID-19 was defined as need for non-invasive ventilation, intensive care unit care, and/or death. Age, gender, ANCA antibody type, ongoing immunosuppressive medication, and estimated glomerular filtration rate were recorded. Results The cohort comprised 310 AAV patients, of whom 29 (9%) were diagnosed with COVID-19. Four deaths were attributed to COVID-19. Fifteen patients (52%) were on prednisolone in the COVID-19 group and 130 (46%) in the non-COVID group, with significantly higher doses in COVID-19 patients (p < 0.01). Ongoing induction therapy was more prevalent in the COVID-19 group (p < 0.01). Severe COVID-19 was diagnosed in 9/29 (31%). Significant risk factors for severe COVID-19 were impaired kidney function (p = 0.01) and more intense immunosuppressive therapy (p = 0.02), with a trend for age (p = 0.07). Maintenance therapy with rituximab was not associated with severe COVID-19. Conclusions Our findings highlight risks and suggest that more attention should be given to optimal AAV treatment in a pandemic situation. They also emphasize the need for continued shielding, mitigation strategies, and effective vaccination of AAV patients.

- OBJECTIVE: To investigate long-term sick leave among primary care patients with musculoskeletal disorders and the predictive value of health-status and sense-of-coherence measures. METHODS: Patients aged 17 to 64 years who, during seven weeks, attended one of six primary care centers because of non-traumatic musculoskeletal pain and who completed the SF-36 health questionnaire and the sense of coherence (SOC) scale at baseline and after one year. RESULTS: Of 189 patients, 36 (19%) were sicklisted for at least three months before and/or after their visit; the most common diagnoses were non-specific soft-tissue or multiple joint, low back, and shoulder pain. The long-term sicklisted patients had significantly worse baseline SF-36 and SOC scores than the non-sicklisted patients; moderate improvement in the SF-36 bodily pain but no improvement in the physical functioning scores occurred. The duration of sick leave at baseline and the SF-36 bodily pain score were significant predictors of continuos one-year work disability. CONCLUSION: Long-term sick leave was common among primary care patients with musculoskeletal pain. The physical functioning and return-to-work outcomes after one year were poor. The SF-36 bodily pain scale might be helpful in identifying at risk patients.

Cone-beam computed tomography, a new low-dose three-dimensional imaging technique for assessment of bone erosions in rheumatoid arthritis : reliability assessment and comparison with conventional radiography – a BARFOT study
- 2018
-
Ingår i: Scandinavian Journal of Rheumatology. - : Informa UK Limited. - 0300-9742 .- 1502-7732. ; 47:3, s. 173-177

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To determine the intra- and inter-observer agreement of erosions detected and scored with cone-beam computed tomography (CBCT) of bones in the hands and feet, and to compare CBCT with conventional radiography (CR) for assessment of bone erosions in patients with long-standing rheumatoid arthritis (RA). Method: Thirty patients with long-standing RA from the Better Anti-Rheumatic PharmacOTherapy (BARFOT) cohort were examined with CBCT and CR of hands and feet at their 15 year follow-up. Intra- and inter-class correlation coefficients (ICCs) were calculated. Erosions were analysed with the total rheumatoid arthritis magnetic resonance imaging erosion score (RAMRIS erosion score) for ICCs with CBCT, and with the modified RAMRIS erosion score (RAMRIS-mod.) for the same locations as used in the Sharp van der Heijde score and Sharp van der Heijde erosion score for CR. Results: All 30 patients showed erosions on CBCT and 26 on CR. The ICCs for both intra- and inter-observer reliability were 0.92–0.99. CBCT showed numerically more erosions than CR for all regions compared, although a statistically significant difference was found only for the metacarpophalangeal joints [median number of eroded joints 1.0 (range 0–14) with CBCT and 0.5 (0–13) with CR, p = 0.044]. Conclusion: CBCT has high reproducibility and is more sensitive than CR in detecting erosions in this cohort of patients with long-standing RA. CBCT has the potential to become an important tool in the detection and follow-up of erosions in patients with RA.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim was to explore dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as an early marker of therapeutic response in patients with rheumatoid arthritis (RA) starting treatment with certolizumab pegol (CZP). Method: In 40 RA patients initiating CZP (27 patients) or 2 weeks of placebo (PCB) followed by CZP (13 patients), DCE-MRI of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints was performed at weeks 0, 1, 2, 4, 8, and 16. Using semi-automated software, three methods for drawing volume regions of interest (ROIs) in MCP2-5 and PIP2-5 were applied: 'Standard' (slices: all; joints: MCP2-5 together and PIP2-5 together), 'Detailed' (slices: slices with high-quality visualization; joints: as Standard), and 'Single-joint' (slices: as Detailed; joints: each joint separately). The number of enhancing voxels (Nvoxel), initial rate of enhancement (IRE), and maximum enhancement (ME) were extracted and analysed for each method. Results: Nvoxel in MCP2-5, and IRE and ME in PIP2-5 decreased statistically significantly (Wilcoxon rank-sum test, p < 0.02-0.03) after 16 weeks of treatment for the Standard method. Nvoxel and ME decreased significantly more in the CZP group than in the PCB group after 1 week of treatment, but not at later time-points. There were no significant changes for DCE-MRI parameters for the Detailed and Single-joint methods. Conclusions: Certain DCE-MRI parameters detected decreased inflammation during CZP treatment in RA patients. Using specific criteria for ROIs, as in the Detailed and Single-joint methods, decreased the statistical power and could not show any changes over time.

- Proteoglycan subunits (PGS) were isolated from bovine articular cartilage of calves and from cows, 18 months and 8 years old respectively. From the latter cartilage of osteoarthrotic and of non-osteoarthrotic sites was taken. PGS were characterized by gel-chromatography on Sepharose 2B columns and subjected to digestion with chondroitinase ABC and with papain. The isolated keratan sulphate-protein cores obtained from chondroitinase digestion were characterized on Sepharose 4B and the chondroitin sulphate chains on Sephadex G-200 gels. A larger molecular size of PGS was found in calf cartilage than in the other samples. This was attributed to the larger molecular size of chondroitin, whereas no change was observed in the keratan sulphate-protein cores. No change was observed in molecular size of PGS, isolated chondroitin sulphates or keratan sulphate-protein cores in osteoarthrosis in compariith non-osteoarthrotic cartilage from the same joint or from younger adult animals.

- OBJECTIVES: Patients with rheumatoid arthritis (RA) are at increased risk of lymphoma. There is no biomarker to indicate future lymphoma risk in RA and it is not known whether factors associated with an increased risk of RA also confer an increased risk of lymphoma. We investigated whether anti-cyclic citrullinated peptide (CCP) antibodies, other autoantibodies, and smoking, are associated with lymphoma development in RA.METHOD: subclasses of anti-CCP antibodies and for 15 antinuclear antibody (ANA)-associated specific autoantibodies. Relative risks were estimated as crude and adjusted odds ratios (adjOR) with 95% confidence intervals (CIs) using logistic regression.RESULTS: We found no association between anti-CCP IgG ≥ 25 units/mL (adjOR 1.4, 95% CI 0.7-2.7), anti-CCP IgG ≥ 500 units/mL (adjOR 1.4, 95% CI 0.7-3.0), anti-CCP Ig of other isotypes, other autoantibodies (adjOR any vs none 0.6, 95% CI 0.3-1.2), or cigarette smoking (adjOR ever vs never 1.1, 95% CI 0.5-2.2) and lymphoma risk among patients with RA.CONCLUSION: In this study, neither anti-CCP antibodies (IgG, IgG1–4, IgM, or IgA), nor other common autoantibodies, nor smoking predicted lymphoma risk in RA

- Objectives: To study anal sphincter morphology, anal sphincter pressure, and rectoanal inhibitory reflex (RAIR) in patients with systemic sclerosis (SSc) complicated by anal incontinence (AI) and to investigate possible risk factors for AI in SSc. Method: Nineteen SSc patients with severe AI were investigated using anal endosonography, anal manometry, and rectal manovolumetry. To determine risk factors for AI, disease characteristics of SSc patients with AI were compared with those of 95 SSc patients without AI; there were five matched SSc patients without AI for each SSc patient with AI. Results: The mean (SD) internal sphincter thickness was 1.3 (0.46) mm in patients with AI, which was thinner (p < 0.001) than reference data from healthy individuals whose internal sphincter measured 2.2 (0.45) mm, whereas the external sphincter thickness did not differ. The mean (SD) resting pressure in AI patients was lower than the reference data from healthy individuals [60 (22) vs. 94 (29) mmHg, p < 0.002] whereas the squeeze pressure did not differ. Centromeric antibodies and features of vascular disease [i.e. the presence of pulmonary arterial hypertension (PAH), digital ulcers, pitting scars, or the need for iloprost infusions] were associated with AI whereas fibrotic manifestations [i.e. modified Rodnan skin score (mRss), the diffuse cutaneous SSc (dcSSc) subset, or low vital capacity (VC)] were not. Conclusions: SSc patients with AI have a thin internal anal sphincter and a low resting pressure. Risk factors for AI among SSc patients are centromeric antibodies and vascular disease, which supports the hypothesis that gastrointestinal involvement in SSc is in part a vascular manifestation of the disease.

- Objective: To compare application of the 1987 American College of Rheumatology (ACR) and 2010 ACR/European League Against Rheumatism (EULAR) classification criteria for diagnosing rheumatoid arthritis (RA) in clinical practice. Method: The medical records of patients with early arthritis attending the Rheumatology Department, Umea University Hospital (n = 1026) were analysed. Patients with synovitis in at least one joint, no diagnosis other than RA being better for explaining the synovitis, and duration of symptoms less than 1 year at first visit, and at least 1 year of follow-up were included consecutively. Fulfilment of the 1987 and 2010 criteria at baseline was evaluated. Sensitivity and specificity for each criterion set, where estimated by using the outcome measures: initiation of methotrexate (MTX) therapy during the first year, and a clinical diagnosis of RA at the 1-year follow-up. Radiographs of hands and feet were evaluated using the Larsen score. Results: The study included 313 patients, of whom 56% fulfilled the 1987 ACR criteria, 74% the 2010 ACR/EULAR criteria, and 53% both sets of criteria at baseline. The sensitivity/specificity for the 1987 and 2010 criteria with MTX within the first year as the outcome measure was 0.68/0.79 and 0.84/0.54, respectively, and with a diagnosis of RA at follow-up 0.72/0.83 and 0.91/0.65, respectively. Older patients (i.e. >= 60 years) more often fulfilled the 2010 criteria. Patients who fulfilled the 2010 ACR/EULAR but not the 1987 ACR criteria had a lower Larsen score at inclusion and after 2 years. Conclusions: Compared with the 1987 ACR criteria, the 2010 ACR/EULAR criteria have higher sensitivity but lower specificity, especially in patients aged >= 60 years. The 1987 ACR criteria are suggested to predict a more erosive disease.

- Objective: The aim of this study was to analyse how support from significant others affects the associations between disease-related variables and sickness absence during the first 2 years after rheumatoid arthritis (RA) diagnosis. Method: Data from 274 people with RA (73% women) of working age (18-63 years) were retrieved from the Swedish early RA cohort TIRA-2. These data concerned disease-related variables (disease activity, activity limitations, pain intensity, and grip force), sickness absence, and perceived support from significant others. Associations of disease-related variables with sickness absence and how these associations were moderated by support from significant others were analysed using zero-inflated negative binomial regression. Results: During the 2 years after diagnosis, higher disease activity was significantly associated with increased odds of sickness absence, a connection strengthened by perceived support from family during the first year. More perceived support was also directly and significantly associated with increased odds of sickness absence during the first year. Conclusions: Support from significant others is related to sickness absence in RA, specifically during the first year after diagnosis. Although patients report high levels of support from significant others, this does not necessarily lead to more positive work outcomes. Therefore, it is important to consider other aspects of support that might influence work outcomes, e.g. type and quality of support. Future research should investigate these forms of support, and when significant others should be encouraged to support in the rehabilitation process to increase the chances of people with RA having a well-functioning and sustainable work life.

- Objective: Suggested predictors of rheumatoid arthritis (RA) include environmental exposure, such as smoking. Our purpose was to investigate potential predictors of RA in a nested case-control study based on a prospective cohort. Method: Between 1991 and 1996, 30 447 persons were included in the Malmö Diet and Cancer Study (MDCS). Individuals who developed RA after inclusion up to 31 December 2004 were identified by linking the database to different registers. Four controls were selected for every case. Data on lifestyle factors were collected in the MDCS. Results: We identified 172 incident cases of RA [36 men/136 women, mean age at diagnosis 63 years, 69% rheumatoid factor (RF) positive, median time from inclusion to diagnosis 5 (range 1-13) years]. In bivariate analyses, baseline smoking [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.31-3.12] and a low level of formal education (i.e. ≤ 8 years; OR 2.42, 95% CI 1.18-4.93 vs. University degree) predicted subsequent development of RA. Infrequent baseline alcohol consumption was a predictor of RA (OR 3.47, 95% CI 1.91-6.30) compared to recent use (within the past month), and individuals with moderate baseline alcohol consumption (3.5-15.2 g/day vs. < 3.5 g/day) tended to have a reduced risk of RA (OR 0.48, 95% CI 0.22-1.05) in multivariate analyses, adjusted for smoking and level of education. Conclusions: Smoking and a low level of formal education were found to be independent predictors of RA. Moderate alcohol consumption may also be associated with a reduced risk.

- Objective: To study whether serum levels of tumour necrosis factor-α (TNF-α), free or bound to etanercept, in biological-naïve adults with rheumatoid arthritis (RA) could predict the long-term efficacy of etanercept, measured as drug survival. Method: We identified 145 biological-naïve patients with RA starting treatment with etanercept at the Department of Rheumatology, Skåne University Hospital (1999–2008), of whom 16 had seronegative and 129 seropositive RA. TNF-α in serum was quantified using enzyme-linked immunosorbent assay in samples from the onset of treatment and at 6 week follow-up. Drug survival time was used to evaluate the long-term efficacy of etanercept. Results: Levels of TNF-α were significantly increased at follow-up compared to at the start. At the 6 week follow-up, circulating TNF-α mainly comprised TNF-α in complex with etanercept. Longer drug survival time correlated with increased TNF-α at 6 week follow-up in the patients with seronegative RA, but not in the seropositive patients. Conclusion: We demonstrated that levels of circulating TNF-α increased in almost all individuals after initiation of treatment with etanercept and that this increase mainly comprised TNF-α in complex with etanercept. More importantly, this increase may predict drug survival in adults with seronegative, but not seropositive, RA and suggests that measuring TNF-α/etanercept complexes in serum may be relevant in patients with seronegative RA.

- Objectives: To investigate, in a population-based cohort of patients with juvenile chronic arthritis (JCA), onset characteristics, progression, outcome, and prognostic factors longitudinally for 5 years. Methods: This cohort consisted of 132 incidence cases identified between 1984 and 1986 in southwestern Sweden followed for 5 years with annual reports of subgroup, joint assessment, disease activity, eye examinations, laboratory measurements, and medication. At the 5-year follow-up, the Childhood Health Assessment Questionnaire (Child-HAQ) was evaluated. European League Against Rheumatism (EULAR) criteria for diagnosis and disease activity were used. Results: During the 5 years only four patients were lost to follow-up, 34% changed subgroup and 8% developed uveitis. At the 5-year follow-up the disease was active in 12% of the patients, stable in 28%, inactive in 25%, and in remission in 34%. Among those examined, 24% had radiological changes, of whom half had advanced changes. The Child-HAQ median score at the 5-year follow-up was 0.13 (range 0.0-1.9). The number of involved joints at inclusion correlated positively with active disease at the 5-year follow-up. Age at disease onset, the number of involved joints, and the number of joints with arthritis correlated positively with continuous disease and Child-HAQ score. Conclusion. Our study shows a diverse disease course during the first 5 years of JCA where one-third changed subgroup and two-thirds did not reach remission. Age of disease onset, the number of involved joints, and the number of joints with arthritis at inclusion were associated with poor outcome at the 5-year follow-up.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of the study was to determine the prevalence of widespread pain (WP) in women with early rheumatoid arthritis (RA) and to compare physical function, activity limitations, health-related quality of life, mental distress, and disease activity between women with WP and non-widespread pain (NWP). Method: This cross-sectional study included 102 women with early RA. Participants were provided with self-reported questionnaires quantifying activity limitations, physical activity, pain intensity, health-related quality of life, and fatigue. Hand-grip force, muscle function test of the lower extremities, erythrocyte sedimentation rate, and number of tender and swollen joints were assessed. Results: One-third (35.9%) of the women fulfilled the American College of Rheumatology criteria for WP 20 months after disease onset. Women with RA + WP had significantly higher 28-joint Disease Activity Score (DAS28) (p = 0.004), number of tender joints (p = 0.001), pain intensity (p < 0.001), fatigue (p < 0.001), Health Assessment Questionnaire score (p < 0.001), and Hospital Anxiety and Depression Scale - Depression (p = 0.001). Furthermore, women with RA + WP showed significantly worse global health (p < 0.001) and physical health (36-item Short Form Health Survey - Physical Component Summary) (p < 0.001). The hand-grip force was found to be significantly reduced (p = 0.001), as was the muscle function of the lower extremities (p < 0.001), for women with RA + WP compared to women with RA + NWP. After adjustment for inflammatory joint disease, the significant differences between the groups remained. Conclusion: A significant group of women with early RA experience WP with a high DAS28 and increased pain intensity level. These women display severe muscle function deficiency in clinical examinations, and report general activity limitations and low psychological and physical health, despite an absence of or low objective signs of inflammation.

- Objectives: The aim of this study was to investigate work status and associated factors in patients with early rheumatoid arthritis (RA), with the emphasis on shoulder function, work-related mechanical exposure, and activity limitations related to the shoulder-arm-hand. Method: Patients with early RA were provided with self-report questionnaires quantifying work-related mechanical exposure and activity limitations. Shoulder function (i.e. isometric muscle strength, shoulder-arm movement, and shoulder pain), hand-grip force, and number of tender and swollen joints were assessed. Results: The study comprised 135 patients (103 women and 32 men), with a mean age of 48 (SD 9.6) years, a mean disease duration of 21 (SD 9.6) months, and a mean Disease Activity Score using 28 joint counts (DAS28) of 3.7 (SD 1.4). The majority (75.6%) were working full- or part-time. Work hours correlated with work-related mechanical exposure (rs = -0.34, p < 0.001) and with physical work load (rs = 0.26, p = 0.0036). Work hours also correlated with shoulder function, that is shoulder-arm movement (rs = 0.34, p < 0.0001), shoulder strength (rs = 0.25, p = 0.0032), and activity-induced shoulder pain (rs = -0.45, p < 0.0001). Significant correlations were found between work hours and hand-grip force (rs = 0.45, p < 0.0001), activity limitations related to the shoulder-arm-hand (using the Disabilities of the Arm, Shoulder and Hand Questionnaire, DASH) (rs = -0.61, p < 0.0001), and DAS28 (rs = -0.43, p < 0.0001). DASH was found to be the only significant (p < 0.001) variable to independently explain the ability of working full-time [odds ratio (OR) 0.40, 95% confidence interval (CI) 0.29-0.55 per 10 increments, area under the receiver operating characteristic (ROC) curve (AUC) 0.81, 95% CI 0.74-0.89]. Conclusions: Work status in early RA is associated with shoulder function and activity limitations related to the shoulder-arm-hand accentuated by work-related mechanical exposure.
