  • Cytokine mRNA profile of alveolar T lymphocytes and macrophages in patients with systemic sclerosis suggests a local Tr1 response
  • 2011
  • Ingår i: Scandinavian Journal of Immunology. - Oslo : Univ.forl.. - 0300-9475 .- 1365-3083. ; 74:3, s. 272-81

    • The development of an autoimmune disease like systemic sclerosis (SSc) is suspected to be driven by an activated T lymphocyte subset, expressing a cytokine profile specific to the disease. To further characterize the type of immune reaction in SSc, we searched for a broad panel of cytokine messenger ribonucleic acids (mRNAs) in T lymphocytes and monocytes/macrophages from paired samples of bronchoalveolar lavage fluid and peripheral blood in 18 patients and 16 age- and sex-matched controls. RNA from CD3(+) T lymphocytes and CD14(+) monocytes/macrophages was examined by means of the reverse transcriptase polymerase chain reaction. SSc alveolar T lymphocytes expressed a cytokine profile suggestive of a mixed Th1/Th2 reaction, showing an increased frequency of mRNA for interleukin (IL)-10, IL-6 and interferon (IFN)γ, while IL-1β, IFNγ and tumour necrosis factor β were expressed in blood T lymphocytes in a higher percentage of patients with SSc than controls. SSc alveolar T cells expressed IL-10 mRNA more often than peripheral T cells, a phenomenon not found in controls and which may point at local IL-10 activation/response in SSc lung. Transforming growth factor β mRNA was present in all alveolar as well as peripheral blood T cell samples in patients and controls. The cytokine mRNA profile in SSc with interstitial lung disease (ILD) was similar to the profile found in SSc without ILD. Our findings point at a mixed Th1/Th2 reaction in SSc and may indicate regulatory T 1 cell activation/response in the lungs of patients with SSc.

  • Cardiovascular event in systemic lupus erythematosus in northern Sweden: Incidence and predictors in a 7-year follow-up study
  • 2012
  • Ingår i: Lupus. - London : SAGE Publications. - 0961-2033 .- 1477-0962. ; 21:4, s. 452-459

    • Introduction. An increased rate of cardiovascular disease (CVD) has been suggested in patients with systemic lupus erythematosus (SLE). The risk for myocardial infarction (MI), coronary artery disease and stroke has been reported as particularly prevalent in younger females compared with the reference population. This study was performed to analyse the standard incidence ratio (SIR) of and predictors for cardiovascular events (CVEs) in patients with SLE from northern Sweden, with a fairly homogenous population. Methods. In 2000 all prevalent patients with SLE (>= 4 American College of Rheumatology [ACR] criteria; n=277) from the four northern-most counties of Sweden were assessed with clinical and laboratory analyses. Seven years follow-up data concerning MI and stroke were extracted from the national registers of hospitalization and death in Sweden. The incidence ratio among the patients was compared with that for the general population from the same catchment area using data from the same register and Statistics Sweden. To identify time to event and CVE predictors, two matched controls for each patient were used and disease related variables as CVD predictors. Results. The SIR for a CVE was 1.27 (95% CI 0.82-1.87) and for females separately aged 40-49 years was 8.00 (95% CI 1.65-23.38). The overall SIR for MI was 2.31 (95% CI 1.34-3.7), for females overall was 1.75 (95% CI 0.84-3.22) and for females aged between 40 and 49 years was 8.7 (95% CI 1.1-31.4). The time to an event was significantly shorter among SLE patients (p<0.001) and was predicted by hypertension adjusted for smoking and disease. High SLEDAI and anti-cardiolipin IgG antibodies predicted an event in Cox proportional hazards regression models adjusted for age and previous MI. Diabetes, smoking ever and sex did not affect the prediction models. Conclusion. The risk of a CVE, or MI, was eight-or nine-fold greater among middle-aged female SLE patients. Time to event was significantly shorter and CVE was associated with SLE-related factors including hypertension and age. Lupus (2012) 21, 452-459.

  • Systemic lupus erythematosus and cardiac risk factors : medical record documentation and patient adherence
  • 2011
  • Ingår i: Lupus. - Houndmills, Basingstoke, Hampshire : Stockton. - 0961-2033 .- 1477-0962. ; 20:10, s. 1057-1062
  • Tidskriftsartikel (refereegranskat)abstract
    • This study explores patients' knowledge of cardiac risk factors (CRFs), analyses how information and advice about CRFs are documented in clinical practice, and assesses patient adherence to received instructions to decrease CRFs. Systemic lupus erythematosus (SLE) patients with >= 4 ACR criteria participated through completing a validated cardiovascular health questionnaire (CHQ). Kappa statistics were used to compare medical records with the self-reported CHQ (agreement) and to evaluate adherence. Two hundred and eleven (72%) of the known patients with SLE participated. The mean age of the patients was 55 years. More than 70% of the SLE patients considered hypertension, obesity, smoking and hypercholesterolaemia to be very important CRFs. The agreement between medical record documentation and patients' reports was moderate for hypertension, overweight and hypercholesterolaemia (kappa 0.42-0.60) but substantial for diabetes (kappa 0.66). Patients' self-reported adherence to advice they had received regarding medication was substantial to perfect (kappa 0.65-1.0). For lifestyle changes in patients with hypertension and overweight, adherence was only fair to moderate (kappa 0.13-0.47). Swedish SLE patients' awareness of traditional CRFs was good in this study. However, the agreement between patients' self-reports and medical record documentation of CRF profiles, and patients' adherence to medical advice to CRF profiles, could be improved.

  • Comparison of the 1987 ACR and 2010 ACR/EULAR classification criteria for rheumatoid arthritis in clinical practice : a prospective cohort study
  • 2013
  • Ingår i: Scandinavian Journal of Rheumatology. - : Informa UK Limited. - 0300-9742 .- 1502-7732. ; 42:5, s. 362-368
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Survivin but not Fms-like tyrosine kinase 3 ligand is up-regulated before the onset of rheumatoid arthritis: a pilot study.
  • 2014
  • Ingår i: Arthritis research & therapy. - : Springer Science and Business Media LLC. - 1478-6362 .- 1478-6354. ; 16:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Antibodies against citrullinated peptides (anti-CCP) and increased levels of cytokines precede the development of rheumatoid arthritis (RA) by several years. Recently, the proteins survivin and Fms-like tyrosine kinase 3 ligand (Flt3L) have been identified as biomarkers of RA associated with joint destruction. Our objective was to investigate the potential of survivin and Flt3L as predictors of RA in samples from patients prior to onset of symptoms.
