Canadian Rheumatology Association Recommendations for Pharmacological Management of Rheumatoid Arthritis with Traditional and Biologic Disease-modifying Antirheumatic Drugs

Objective. The Canadian Rheumatology Association (CRA) has developed recommendations for the pharmacological management of rheumatoid arthritis (RA) with traditional and biologic disease-modifying antirheumatic drugs (DMARD) in 2 parts. Part 1 is reported here. Methods. The CRA Therapeutics Committee assembled a national working group of RA clinical experts, researchers, patient consumers, and a general practitioner. Treatment questions were developed a priori based on results of a national needs assessment survey. A systematic review of all clinical practice guidelines and consensus statements regarding treatment with traditional and biologic DMARD in patients with RA published between January 2000 and June 2010 was performed in Medline, Embase, and CINAHL databases, and the grey literature. Guideline quality was assessed by 2 independent reviewers, and guideline characteristics, recommendations, and supporting evidence from observational studies and randomized controlled trials were synthesized into evidence tables. The full working group reviewed the evidence tables and developed recommendations using a modified Delphi technique. Results. Five overarching principles and 26 recommendations addressing general RA management strategies and treatment with glucocorticoids and traditional and biologic DMARD were developed for rheumatologists, other primary prescribers of RA drug therapies, and patients with RA. Conclusion. These recommendations were developed based on a synthesis of international guidelines, supporting evidence, and expert consensus considering the Canadian healthcare context with the intention of promoting best practices and improving healthcare delivery for persons with RA.

Frequency and impact of symptoms experienced by patients with systemic sclerosis: results from a Canadian National Survey

OBJECTIVE Knowledge about the range of symptoms experienced by patients with SSc, and their impact on daily functioning is limited. The objective of the present study was to identify symptoms of SSc that patients rated as frequent and that highly impacted their ability to carry out daily activities. METHODS A total of 464 persons with SSc responded to the Canadian Scleroderma Patient Survey of Health Concerns and Research Priorities, including questions regarding the frequency and impact of 69 SSc symptoms. Descriptive analyses were performed dichotomizing symptom frequencies as never or rarely vs sometimes, most of the time or always and symptom impact on daily activities as no or minimal impact vs moderate to severe impact. RESULTS The five highest rated symptoms in terms of frequency and moderate to severe impact on daily activities, respectively, were: fatigue (89 and 72%), RP (86 and 67%), hand stiffness (81 and 59%), joint pain (81 and 64%) and difficulty sleeping (76 and 59%). In addition to these symptoms, items related to decreased hand function (difficulty making a fist and difficulty holding objects) and pain (muscle pain and joint tenderness) were frequently endorsed and commonly associated with moderate to severe impact on daily activities. CONCLUSION This study confirmed the importance for quality of life of core symptoms of SSc, such as pain, fatigue and limitations in hand function. It also identified areas with very little research, such as sleep problems, that appear to play important roles in daily functioning, and that merit more focused study.

Reliability and validity of the center for epidemiologic studies depression scale in patients with systemic sclerosis.

OBJECTIVE Reported rates of depressive symptoms in patients with systemic sclerosis (SSc) are high. No depression assessment tools, however, have been validated for patients with SSc. Our objective was to assess the internal consistency reliability, convergent validity, and structural/construct validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in patients with SSc. METHODS We conducted a cross-sectional, multicenter study of 470 SSc patients. Internal consistency reliability was assessed with Cronbachs alpha and structural/construct validity with confirmatory factor analysis. RESULTS Internal consistency reliability was good for the overall CES-D scale (alpha = 0.88) and for its 4 factors (alpha = 0.67-0.88). Correlations of the CES-D total score were -0.73 with mental health, -0.36 with physical health, 0.41 with disability, and 0.44 with pain. The 4-factor model originally found in the general population and validated for patients with rheumatoid arthritis (depressed affect, somatic/vegetative, [lack of] positive affect, and interpersonal factors) fit the data well, as did a second-order version of the same model with an overarching depression factor that loaded onto each of the 4 first-order factors. The 4-factor model fit the SSc data better than alternative models. CONCLUSION Internal consistency reliability and convergent validity were good, the 4-factor structure reported in the general population was replicated, and a second-order model with an overarching depression factor fit well. These findings indicate that the CES-D is a valid and reliable measure of depressive symptoms for patients with SSc.

Prevalence, severity, and clinical correlates of pain in patients with systemic sclerosis†

Large descriptive studies of pain in systemic sclerosis (SSc) are lacking. The present study estimated prevalence, severity, and associations between SSc clinical variables and pain in all patients with SSc and in limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subsets.

The clinimetric properties of the World Health Organization Disability Assessment Schedule II in early inflammatory arthritis.

OBJECTIVE To assess the clinimetric properties of a new health-related quality of life (HRQOL) instrument, the World Health Organization Disability Assessment Schedule II (WHODAS II), in patients with early inflammatory arthritis. METHODS Internal consistency as well as criterion, construct, and discriminative validity of the WHODAS II were assessed in 172 patients with early inflammatory arthritis who completed the WHODAS II, the Medical Outcomes Study Short Form 36 (SF-36), and other measures of disease severity, functioning, pain, depression, and resource use. Test-retest reliability of the WHODAS II was assessed by having a subset of 20 patients complete the WHODAS II a second time, 1 week after the first assessment. RESULTS The WHODAS II had high internal consistency (Cronbachs alpha = 0.96 for patients working or in school and 0.93 for patients not working or in school). Test-retest intraclass correlation coefficients of the WHODAS II total score and subscales ranged from 0.82-0.96. The WHODAS II total score was strongly correlated with the SF-36 physical component score (Kendalls tau-b 0.51, P < 0.001) and moderately correlated with the SF-36 mental component score (tau-b 0.43, P < 0.001). WHODAS II correlations with disease outcomes ranged from Kendalls tau-b 0.15-0.55. The WHODAS II significantly differentiated between every aspect of disease severity assessed with the exception of measures of health resource use. CONCLUSION The WHODAS II is a valid and reliable measure of HRQOL in cross-sectional studies of patients with early inflammatory arthritis. Research is still required to investigate potential item redundancy and determine its usefulness in longitudinal studies.

Psychological health and well-being in systemic sclerosis: State of the science and consensus research agenda.

Introduction Systemic sclerosis (SSc; scleroderma) is a multisystem disorder characterized by disturbance in fibroblast function, microvascular disease, and immune system activation, culminating in fibrosis of the skin and internal organs (1,2). SSc is associated with extensive morbidity, including disfiguring skin thickening, finger ulcers, joint contractures, pulmonary hypertension, interstitial lung disease, chronic diarrhea, and renal failure (1,2). The rate of disease onset is highest between 30 and 50 years of age, with the risk for women being 4 to 5 times higher than for men (3,4). Median survival time from diagnosis is 11 years, and patients are 3.7 times more likely to die within 10 years of diagnosis (44.9% mortality) than age-, sex-, and race-matched individuals without SSc (12.0% mortality) (3).

Symptoms of depression predict the trajectory of pain among patients with early inflammatory arthritis: a path analysis approach to assessing change.

Objective. To assess the longitudinal relationships, including directionality, among chronic pain, symptoms of depression, and disease activity in patients with early inflammatory arthritis (EIA). Methods. One hundred eighty patients with EIA completed an examination, including swollen joint count, and were administered the Center for Epidemiological Studies Depression Scale (CES-D) and the McGill Pain Questionnaire (MPQ) at 2 timepoints 6 months apart. Cross-lagged panel path analysis was used to simultaneously assess concurrent and longitudinal relationships among pain, symptoms of depression, and number of swollen joints. Results. Pain, symptoms of depression, and number of swollen joints decreased over time (p < 0.001) and were prospectively linked to pain, symptoms of depression, and number of swollen joints, respectively, at 6 months. Symptoms of depression and pain were correlated with each other at baseline (0.47) and at 6-month followup assessments (0.28). Baseline symptoms of depression significantly predicted pain symptoms at 6 months (standardized regression coefficient = 0.28, p = 0.001), whereas pain and disease activity did not predict the course of any other variable after controlling for baseline values. Conclusion. Symptoms of depression predicted the trajectory of pain from baseline to 6 months. In addition, there were reciprocal/bidirectional associations between pain and symptoms of depression over time. More research is needed to better understand the relationship between pain and depressive symptoms and how to best manage patients with EIA who have high levels of both.

High rates of depressive symptoms among patients with systemic sclerosis are not explained by differential reporting of somatic symptoms.

OBJECTIVE Between 36% and 65% of patients with systemic sclerosis (SSc) report symptoms of depression above cutoff thresholds on self-report questionnaires. The objective of this study was to assess whether these high rates result from differential reporting of somatic symptoms related to the high physical burden of SSc. METHODS Symptom profiles reported on the Center for Epidemiologic Studies Depression Scale (CES-D) were compared between a multicenter sample of 403 patients with SSc and a sample of respondents to an Internet depression survey, matched on total CES-D score, age, race/ethnicity, and sex. An exact nonparametric generalized Mantel-Haenszel procedure was used to identify differential item functioning between groups. RESULTS Patients with SSc reported significantly higher frequencies (moderate to large effect size; P < 0.01) on 4 CES-D somatic symptom items: bothered, appetite, effort, and sleep. Internet respondents had higher item scores on 2 items that assessed interpersonal difficulties (unfriendly, large effect size; P < 0.01; disliked, large effect size; P < 0.01) and on 2 items that assessed lack of positive effect (happy, moderate effect size; P = 0.01; enjoy, large effect size; P < 0.01). Adjustment of standard CES-D cutoff criteria for potential bias due to somatic symptom reporting resulted in a reduction of only 3.6% in the number of SSc patients with significant symptoms of depression. CONCLUSION High rates of depressive symptoms in SSc are not due to bias related to the report of somatic symptoms. The pattern of differential item functioning between the SSc and Internet groups, however, suggests some qualitative differences in depressive symptom presentation.

Incident myocardial infarction associated with major types of arthritis in the general population: a systematic review and meta-analysis

Objective To synthesise, quantify and compare risks for incident myocardial infarction (MI) across five major types of arthritis in population-based studies. Methods A systematic search was performed in MEDLINE, EMBASE and CINAHL databases with additional manual/hand searches for population-based cohort or case-control studies published in English of French between January 1980 and January 2015 with a measure of effect and variance for associations between incident MI and five major types of arthritis: rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), gout or osteoarthritis (OA), adjusted for at least age and sex. All search screening, data abstraction quality appraisals were performed independently by two reviewers. Where appropriate, random-effects meta-analysis was used to pool results from studies with a minimum of 10 events. Results We identified a total of 4, 285 articles; 27 met review criteria and 25 criteria for meta-analyses. In studies adjusting for age and sex, MI risk was significantly increased in RA (pooled relative risk (RR): 1.69, 95% CI 1.50 to 1.90), gout (pooled RR: 1.47, 95% CI 1.24 to 1.73), PsA (pooled RR: 1.41, 95% CI 1.17 to 1.69), OA (pooled RR: 1.31, 95% CI 1.01 to 1.71) and tended towards increased risk in AS (pooled RR: 1.24, 95% CI 0.93 to 1.65). Traditional risk factors were more prevalent in all types of arthritis. MI risk was attenuated for each type of arthritis in studies adjusting for traditional risk factors and remained significantly increased in RA, PsA and gout. Conclusions MI risk was consistently increased in multiple types of arthritis in population-based studies, and was partially explained by a higher prevalence of traditional risk factors in all types of arthritis. Findings support more integrated cardiovascular (CV) prevention strategies for arthritis populations that target both reducing inflammation and enhancing management of traditional CV risk factors.

Identifying Target Areas of Treatment for Depressed Early Inflammatory Arthritis Patients

Background: The goal of this study was to identify target areas for psychosocial intervention for depressed patients with earlyinflammatory arthritis. Methods:One hundred and sixty-five patients with early inflammatory arthritis (≧1 joint with synovitis for ≧6 weeks and <1 year with a diagnosis of either rheumatoid or undifferentiated inflammatory arthritis) were referred to the McGill Early Arthritis Registry (McEAR) by their rheumatologist. McEAR patients agree to periodic physical exams and to completing questionnaires. Demographic, disease and psychosocial factors were compared between patients screening positive and negative for depression using independent samples t tests and Pearson’s χ2 test and then were entered into a logistic regression model examining the likelihood of screening positive for depression. Results: Thirty-eight (23%) patients screened positive for depressive symptoms. Patients with symptoms of depression had significantly worse disease severity, disability, and pain, engaged in more emotional preoccupation coping, had less self-efficacy for pain and other arthritis-related symptoms, smaller social networks and were less satisfied with social support than the nondepressed group. In logistic regression analyses, pain and emotional preoccupation coping were positively related to the likelihood of screening positive for depression, while satisfaction with social support was negatively related to the likelihood of screening positive for depression Conclusion: Higher pain levels, emotional preoccupation coping and dissatisfaction with social support were related to depressive symptoms in this study. This suggests that the optimal care of depressed patients with inflammatory arthritis would include a psychosocial approach that addresses these specific target areas.
