- 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.

- 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.

- 2020
-
In: Scandinavian Journal of Rheumatology. - : Informa UK Limited. - 0300-9742 .- 1502-7732. ; 49:2, s. 105-111
-
Journal article (peer-reviewed)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.

The role of support from significant others in the association between disease-related factors and sickness absence in early rheumatoid arthritis : a longitudinal study
- 2021
-
In: Scandinavian Journal of Rheumatology. - : TAYLOR & FRANCIS LTD. - 0300-9742 .- 1502-7732. ; 50:6, s. 427-434
-
Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- Objective: Cardiovascular disease (CVD) is increased among patients with rheumatoid arthritis (RA). The underlying cause is not clear. In this prospective study, patients with early RA were investigated for associations between subclinical atherosclerosis and CVD risk factors as well as inflammation.Method: At diagnosis, RA patients were recruited into a prospective study. A subgroup was included (n = 55) for ultrasound measurements of intima–media thickness (IMT) at inclusion (T0), and after 5 years (T5) and 11 years (T11). Thirty-one age and gender-matched controls were also included for comparison.Results: IMT increased significantly between T0 and T11 among patients and controls (p < 0.0001). No statistically significant differences in IMT between patients and controls were detected at T11, T5, or T0 (p > 0.05 for all). In simple regression models, IMT at T11 was significantly associated with age (p < 0.0001), as well as systolic blood pressure at T0 (p < 0.01) and T11 (p < 0.01) among RA patients. Furthermore, the composite Systematic COronary Risk Evaluation (SCORE) measurements (p < 0.0001) and Reynolds risk score (p < 0.01) and the radiographic Larsen score (p < 0.05) at T0 were all significantly associated with IMT at T11. Results from conditional logistic regression analysis showed an increased progression rate between T0 and T11 in the RA group compared with controls (p < 0.05).Conclusion: We found increased atherosclerotic development among patients with RA compared with controls 11 years after diagnosis. The atherosclerotic burden was associated with disease severity at baseline.

Journal article (peer-reviewed)abstract
- This study aimed to identify lifestyle factors associated with gout in patients with prevalent gout compared to the general population.Adult patients with gout identified in primary and secondary care in Western Sweden between 2015 and 2017 were sent a questionnaire asking about demographics, lifestyle, and comorbidities. Five age- and gender-matched controls were identified in a random sample of 52348 individuals aged 16-84years who participated in the National Public Health survey in Sweden, year 2015. Logistic regression models were used to compare cases and controls with regard to lifestyle factors and comorbidities.Of the 1589 invited gout patients, 868 (55%) responded. After matching for age and gender, 728 were included in the analysis (82.4% male; mean±sd age 69.3±10.5 years for men and 71.8±9.9 years for women with gout). Male and female gout patients were significantly more likely to be overweight or obese (men 79% vs 66%; women 78.5% vs 65.3%), to have binge-drinking behaviour (men 29.9% vs 11%; women 13.7% vs 2.9%), and to be ex-smokers, compared to controls. Moreover, male gout patients reported lower levels of physical activity, while diabetes and hypertension were more common in both genders with gout than in controls.In this questionnaire study, gout patients reported significantly more obesity and binge-drinking behaviour and less physical activity than controls. This suggests that there are great unmet needs for the management of lifestyle factors, particularly regarding overweight/obesity and binge drinking, in patients with gout.

Journal article (peer-reviewed)abstract
- Compare characteristics, sex differences, and management of gout in Sweden and the UK.The results from two separate primary care gout surveys from Sweden and the UK were compared. Participants aged ≥18 years with gout were sent a questionnaire asking about lifestyle, gout characteristics, uratelowering therapy (ULT), comorbidities, disability, and disease impact. For sex comparison, participants were pooled across countries.In total, 784 (80% male) participants from Sweden and 500 (87% male) from the UK were included. Swedish patients were significantly older at gout onset, mean (SD) age 72 (12) versus 63 (13) years, (p<0.0001), with more comorbidities, and more frequent use of ULT (48% vs 35%, p=0.0005, age-adjusted). Use of alcohol and diuretics was significantly more common among UK patients, who also reported a higher number of gout flares, mean (SD) 2.2 (1.7) versus 1.6 (3.6), (p=0.003) age-adjusted. Females with gout were older at gout onset, mean (SD) age 67 (13) versus 56 (15), (p<0.0001), more often obese, and reported higher use of diuretics. Furthermore, females reported greater impact of gout, more pain and physical limitations, whereas no sex differences were seen in ULT or flares.In the UK, gout was more frequently associated with modifiable risk factors. People with gout in Sweden were more commonly taking ULT and had lower frequency of gout flares and impact of gout. Females with gout more commonly took diuretics, had higher body mass index, and reported greater physical disability, which should be considered when managing gout in women.

Treatment with a tissue-selective oestrogen complex does not affect disease pathology but reduces pre-BI cells in lupus-prone mice.
- 2024

Journal article (peer-reviewed)abstract
- Systemic lupus erythematosus (SLE or lupus) is an autoimmune disease characterized by B-cell dysfunction, production of autoantibodies, and immune complex formation. Lupus is overrepresented in females, indicating that sex hormones play a role in the pathophysiology. Treatment with a tissue-selective oestrogen complex (TSEC) containing conjugated oestrogens and the selective oestrogen receptor modulator bazedoxifene (BZA) protects against postmenopausal vasomotor symptoms and osteoporosis, but its impact on organ damage in lupus is not fully understood.We used ovariectomized MRL/lpr mice, treated with two different physiological doses of 17β-oestradiol-3-benzoate (E2), BZA, or TSEC (E2 plus BZA), to assess early and late B-cell development and to determine histological disease manifestations in the kidneys and salivary glands.TSEC treatment reduced the frequency of the pre-BI population in bone marrow to levels equivalent to treatment with physiological doses of E2 alone but did not affect any of the other examined B-cell populations. Our earlier studies indicated that TSEC treatment did not aggravate disease development in ovariectomized MRL/lpr mice, while protecting against trabecular bone loss. Here, we follow up on our previous study and show that neither ovariectomy alone nor TSEC treatment of ovariectomized MRL/lpr mice influenced perivascular lymphocyte infiltration to the kidneys or salivary glands.TSEC does not aggravate a mouse model of lupus, when given in doses that protect against postmenopausal lupus-associated bone loss. This indicates that further investigations into TSEC as a treatment for osteoporosis or vasomotor symptoms in postmenopausal women with SLE are warranted.

Autoantibodies are major predictors of arthritis development in patients with anti-citrullinated protein antibodies and musculoskeletal pain
- 2021
-
In: Scandinavian Journal of Rheumatology. - : Taylor & Francis Group. - 0300-9742 .- 1502-7732. ; 50:3, s. 189-197

Journal article (peer-reviewed)abstract
- Objectives: Predictors of arthritis development are highly warranted among patients with anti-citrullinated protein antibodies (ACPAs) and musculoskeletal symptoms to optimize clinical management. We aimed to identify clinical and laboratory predictors of arthritis development, including biochemically assessed alcohol consumption, among ACPA-positive patients with musculoskeletal pain.Method: 82 ACPA-positive individuals with musculoskeletal pain but no clinical arthritis were followed for a median of 72 months (interquartile range 57–81 months). We evaluated the prognostic value of baseline clinical and laboratory factors including smoking, symptom duration, age, gender, shared epitope, rheumatoid factor (RF), anti-carbamylated protein antibodies, ACPA levels, erythrocyte sedimentation rate, C-reactive protein levels, tender joint count, patient-reported general well-being, 28-joint Disease Activity Score, and alcohol consumption as measured by phosphatidyl ethanol (PEth) levels in whole blood.Results: During follow-up, 48% developed at least one arthritis. Multivariable analysis revealed an increased risk of arthritis development with RF positivity [hazard ratio (HR) = 2.3, 95% confidence interval (CI) 1.1–4.8, p = 0.028] and higher ACPA levels (HR = 1.0, 95% CI 1.000–1.001, p = 0.002). High levels of RF (HR = 4.4, 95% CI 1.7–11) entailed the highest HR in this ACPA-positive population. Neither clinical characteristics nor alcohol consumption measured by PEth conferred significant prognostic value.Conclusions: ACPA levels and concurrent presence of RF are independent predictors of arthritis development among ACPA-positive patients with musculoskeletal pain. The results are compatible with a dose–response relationship between RA-related autoantibodies and risk of arthritis development.
