- OBJECTIVES: Antibodies against anti-CD74 are related to axial spondyloarthritis (axSpA). The objectives were (i) to study IgA anti-CD74 in radiographic (r)-axSpA patients in the Backbone cohort and to calculate the sensitivity and specificity of anti-CD74, (ii) to study the fluctuation of IgA anti-CD74 levels in prospectively collected samples, and (iii) to explore the relation between IgA anti-CD74 and radiographic spinal changes.METHODS: IgA anti-CD74 was analysed by ELISA in 155 patients with r-axSpA and age- and sex-matched controls. BASDAI, ASDAS, BASFI and BASMI were assessed and spinal radiographs were scored for r-axSpA-related changes with mSASSS. Previously donated samples, before inclusion in the Backbone study, were identified in the Medical Biobank of Northern Sweden.RESULTS: A total of 155 patients comprising 69% men and 31% women, age [mean (s.d.)] 55.5 (11.4) years and 152 (98.1%) HLA-B27 positive, were included. The plasma level of IgA anti-CD74 was significantly higher in the patients [median (interquartile range), 12.9 (7.9-17.9) U/ml] compared with controls [10.9 (7.2-14.6) U/ml, P = 0.003]. IgA anti-CD74 was above the cut-off level of 20 U/ml in 36/155 (23.2%) patients and in 15/151 (9.9%) controls (P = 0.002). Multivariable logistic regression analyses revealed ≥1 syndesmophyte associated with IgA anti-CD74 (odds ratio 5.64; 95% CI: 1.02, 35.58; P = 0.048) adjusted for hsCRP, smoking, BMI, sex and age. No distinct pattern of IgA anti-CD74 over time was revealed.CONCLUSION: Plasma levels of IgA anti-CD74 were increased in r-axSpA and independently associated with radiographic spinal changes, which suggests that IgA anti-CD74 could play a role in the pathogenies of r-axSpA.

- Objectives. To investigate metabolic features that may predispose to GCA in a nested case-control study. Methods. Individuals who developed GCA after inclusion in a population-based health survey (the Malmo Preventive Medicine Project; N = 33 346) were identified and validated through a structured review of medical records. Four controls for every validated case were selected from the database. Results. A total of 76 cases with a confirmed incident diagnosis of GCA (61 % female, 65% biopsy positive, mean age at diagnosis 70 years) were identified. The median time from screening to diagnosis was 20.7 years (range 3.0-32.1). Cases had significantly lower fasting blood glucose (FBG) at baseline screening compared with controls [mean 4.7 vs 5.1 mmol/l (s.D. overall 1.5), odds ratio (OR) 0.35 per mmol/l (95% CI 0.17, 0.71)] and the association remained significant when adjusted for smoking [OR 0.33 per mmol/l (95% CI 0.16, 0.68)]. Current smokers had a reduced risk of GCA [OR 0.35 (95% CI 0.18, 0.70)]. Both cholesterol [mean 5.6 vs 6.0 mmol/l (s.D. overall 1.0)] and triglyceride levels [median 1.0 vs 1.2 mmol/l (s.D. overall 0.8)] were lower among the cases at baseline screening, with significant negative associations with subsequent GCA in crude and smoking-adjusted models [OR 0.62 per mmol/l (95% CI 0.43, 0.90) for cholesterol; 0.46 per mmol/l (95% CI 0.27, 0.81) for triglycerides]. Conclusion. Development of GCA was associated with lower FBG and lower cholesterol and triglyceride levels at baseline, all adjusted for current smoking, suggesting that metabolic features predispose to GCA.

Journal article (peer-reviewed)abstract
- Objectives. Patients with rheumatoid arthritis (RA) and clinicians have different views about benefits from treatments. More knowledge is needed about how patients assess outcomes in order to update current measurements. Methods. Focus group interviews were performed at four Swedish rheumatology clinics. A total of 25 patients with RA were included, representing a wide range of ages and disease duration. Predetermined topics relating to important outcomes from and satisfaction/dissatisfaction with RA treatments were discussed. Results. The participants’ initial outcome assessments included physical and psychosocial items, which comprised overall treatment goals such as impairment in social roles, fatigue, daily activities and self-confidence. The identified themes were ‘Normal life’, ‘Physical capacity’, ‘Independence’ and ‘Well-being’. Satisfaction with treatment was associated with the quality of communication between staff and the patient. The participants assumed this as a prerequisite for a treatment to work. Patients wanted to be accepted as experts on their own bodies, and expected all clinicians to be experts on RA. This made it possible for patients to ‘take charge’ of their life situation. Good resources for and access to rheumatology care were desired. Conclusions. Suggesting a holistic approach to rheumatology care, the study results indicate that the illness and outcomes have to be evaluated within an individual RA patient's total life situation, described in the identified themes: ‘Normal life’, ‘Physical capacity’, ‘Independence’ and ‘Well-being’. Development and validation of measurements covering these issues is suggested. More research is needed about communication and how patients experience their roles in the rheumatology clinic.

- Treatment with CTLA-4Ig blocks T cell activation and is clinically effective in rheumatoid arthritis (RA). However, it is unknown if specific CD4+ T cell subsets in blood at baseline predict remission after CTLA-4Ig, or other biological treatments with different modes of action, and how treatment affects CD4+ T cells in patients with untreated early RA (eRA).This study included 60 patients with untreated eRA from a larger randomised trial. They were treated with methotrexate combined with CTLA-4Ig (abatacept, n=17), anti-IL6 receptor (tocilizumab, n=21) or anti-TNF (certolizumab-pegol, n=22). Disease activity was assessed by clinical disease activity index (CDAI), DAS28, swollen joint counts, tender joint counts, CRP and ESR. The primary outcome was CDAI remission (CDAI≤2.8) at week 24. Proportions of 12 CD4+ T cell subsets were measured by flow cytometry at baseline and after 4, 12 and 24weeks of treatment.In patients treated with CTLA-4Ig, the proportions of PD-1+TFh and CTLA-4+ conventional CD4+ T cells at baseline predicted CDAI remission at week 24. CD4+ T cell subset proportions could not predict remission after treatment with anti-IL6R or anti-TNF. The percentage of regulatory T cells (Tregs) expressing CTLA-4 decreased in all treatment arms by 24weeks, but only CTLA-4Ig treatment significantly reduced the proportions of Tregs and PD-1+T follicular helper (TFh) cells.These findings indicate that circulating proportions PD-1+TFh and CTLA-4+ conventional CD4+ T cells at baseline may serve as predictive biomarkers for remission in early RA after CTLA-4Ig treatment.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To determine the frequency of osteoporosis and possible risk factors of low bone mineral density (BMD) in women with systemic lupus erythematous (SLE) in western Sweden. In addition, to evaluate if adequate anti-osteoporotic treatment was provided. METHODS: BMD was measured at radius, lumbar spine and hip by dual X-ray absorptiometry (DXA). An 'expected' control BMD was calculated for each patient. Simple and multiple linear regression analyses were performed to determine associations between BMD and demographic and disease-related variables. RESULTS: One hundred and sixty-three women were included. Median age was 47 (20-82) yrs, 89 (55%) were post-menopausal and 85 (52%) were taking glucocorticosteroids. BMD was significantly reduced in all measured sites compared with expected BMD. Thirty-seven (23%), 18 (11%) and 6 (4%) of the patients were osteoporotic in at least one, two and three or more measured locations. Bisphosphonates were used by 23 (27%) of patients taking glucocorticosteroids and 13 (35%) with osteoporosis. High age and low weight or BMI were associated with low BMD in all measured sites. In total hip, high SLICC/American Collage of Rheumatology (ACR), ESR and 'combinations of DMARD' were additional markers of low BMD. High S-creatinine was associated with low BMD in lumbal spine whereas high S-creatinine and CRP were markers in radius. CONCLUSION: Women with SLE are at greater risk of osteoporosis compared with controls and few are treated adequately. Factors associated with low BMD in SLE are high age and low weight but also markers of inflammation, impaired kidney function and disease damage, however glucocorticosteroids were not associated.

Journal article (peer-reviewed)abstract
- RA predominantly affects post-menopausal women and is strongly associated with development of generalised osteoporosis. To find treatments that target both joint manifestations and osteoporosis in RA is desirable. The third generation of selective oestrogen receptor modulators (SERMs) [lasofoxifene (LAS) and bazedoxifene (BZA)] are new treatment options for post-menopausal osteoporosis. The aim of this study was to investigate the effects of LAS and BZA on arthritic disease and inflammation-associated bone loss using CIA in mice.
