The importance of disease associations and concomitant therapy for the long-term management of psoriasis patients
It is well established that several inflammatory-type conditions, such as arthritis, diabetes, cardiovascular disease, and irritable bowel disease exist comorbidly and at an increased incidence in patients with psoriasis. Psoriasis and other associated diseases are thought to share common inflammatory pathways. Conditions such as these, with similar pathogenic mechanisms involving cytokine dysregulation, are referred to as immune-mediated inflammatory diseases (IMIDs). Considerable evidence for the genetic basis of cormobidities in psoriasis exists. The WHO has reported that the occurrence of chronic diseases, including IMIDs, are a rising global burden. In addition, conditions linked with psoriasis have been associated with increasing rates of considerable morbidity and mortality. The presence of comorbid conditions in psoriasis patients has important implications for clinical management. QoL, direct health care expenditures and pharmacokinetics of concomitant therapies are impacted by the presence of comorbid conditions. For example, methotrexate is contraindicated in hepatic impairment, while patients on ciclosporin should be monitored for kidney function. In addition, some agents, such as beta blockers, lithium, synthetic antimalarial drugs, NSAIDs and tetracycline antibiotics, have been implicated in the initiation or exacerbation of psoriasis. Consequently, collaboration between physicians in different specialties is essential to ensuring that psoriasis treatment benefits the patient without exacerbating associated conditions
Elevated triglyceride and cholesterol levels after intravenous antitumour necrosis factor-? therapy in a patient with psoriatic arthritis and psoriasis vulgaris
Smoking, low formal level of education, alcohol consumption, and the risk of rheumatoid arthritis.
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

Prognostic factors for change in self-reported anxiety and depression in spondyloarthritis patients : data from the population-based SpAScania cohort from southern Sweden
Objectives: Anxiety and depression symptoms are more common in patients with spondyloarthritis (SpA) than in the general population. This study describes prognostic factors for change in self-reported anxiety and depression over 2 years in a well-defined SpA cohort. Method: In 2009, 3716 adult patients from the SpAScania cohort received a postal questionnaire to assess quality of life (QoL) and physical and mental functioning. A follow-up survey was performed in 2011. The Hospital Anxiety and Depression Scale indicated ‘no’, ‘possible’, and ‘probable’ cases of anxiety and depression. Transitions between the three different categories were analysed and logistic regression analysis determined prognostic factors (patient-reported outcomes and characteristics) for improvement or deterioration. Results: In total, 1629 SpA patients responded to both surveys (44%) (mean ± SD age 55.8 ± 13.1 years, disease duration 14.6 ± 11.7 years); 27% had ankylosing spondylitis, 55% psoriatic arthritis, and 18% undifferentiated SpA. The proportion of patients reporting possible/probable anxiety decreased from 31% to 25% over 2 years, while no changes in depression were seen. Factors associated with deterioration or improvement were largely the same for anxiety as for depression: fatigue, general health, QoL, level of functioning, disease activity, and self-efficacy. However, reporting chronic widespread pain (CWP) at baseline increased the risk of becoming depressed and decreased the probability of recovering from anxiety. Conclusion: Self-reported anxiety and depression is common and fairly stable over time in SpA patients. The association between mental health and CWP indicates that both comorbidities need to be acknowledged and treated in the clinic
Responsiveness of different dynamic contrast-enhanced magnetic resonance imaging approaches: a post-hoc analysis of a randomized controlled trial of certolizumab pegol in rheumatoid arthritis
Multiplex cytokine analyses in patients with rheumatoid arthritis require use of agents blocking heterophilic antibody activity
Objectives: Heterophilic antibodies, such as rheumatoid factor (RF), are known to interfere with enzyme-linked immunosorbent assays (ELISAs). Treatment of rheumatoid arthritis (RA) with tumour necrosis factor (TNF)-α blockers is well established. The aims of this study were to develop a protocol for blocking the interaction of present heterophilic antibodies and to validate this procedure by evaluating the effect on correlations of cytokine levels to clinical response in RA patients treated with adalimumab. Method: Fourteen patients with active RA were evaluated at baseline and 3 months after starting adalimumab treatment. Cytokines were analysed with a commercial 12-plex bead ELISA. To block interference by RF, a commercial blocker (HeteroBlock) was used. To determine the optimal concentration of HeteroBlock, patient sera were analysed with different concentrations of HeteroBlock. Subsequently, baseline and follow-up sera from the 14 patients were analysed and correlated with clinical outcome. Results: Measured cytokine levels were reduced in the majority of samples when adding the blocker. The optimal concentration of HeteroBlock was 1600 μg/mL of serum. Sera with high RF levels were more prone to produce false positive values, although some RF-negative sera also demonstrated evidence of interference. HeteroBlock did not interfere with the analysis. In RA patients treated with adalimumab, changes in interleukin (IL)-6 levels between baseline and follow-up correlated with changes in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in sera with added HeteroBlock. Conclusions: When analysing sera from patients with RA with multiplex bead ELISA, the assay should be evaluated for interference by heterophilic antibodies, and if present corrected with, for example, HeteroBlock
