Having More Tender Than Swollen Joints Is Associated With Worse Patient-Reported Outcomes in Patients With Early RA.

BACKGROUND/OBJECTIVE: In patients with rheumatoid arthritis (RA), high tender-swollen joint differences (TSJDs) have been associated with worse outcomes. A better understanding of the phenotype and impact of high TSJD on patient-reported outcomes (PROs) in early RA may lead to earlier personalized treatment targeting domains that are important to patients today. Our objectives were to evaluate the impact of TSJD on updated PROs in patients with early RA over 1 year and to determine differences in associations by joint size. METHODS: This longitudinal cohort study followed patients with active, early RA enrolled in the Canadian Early Arthritis Cohort between 2016 and 2022, who completed clinical assessments and PROMIS-29 measures over 1 year. Twenty-eight joint counts were performed and TSJDs calculated. Adjusted associations between TSJD and PROMIS-29 scores were estimated using separate linear-mixed models. Separate analyses of large versus small-joint TJSDs were performed. RESULTS: Patients with early RA (n = 547; 70% female; mean [SD] age, 56 [15] years; mean [SD] symptom duration, 5.3 [2.9] months) were evaluated. A 1-point increase in TSJD was significantly associated with worse PROMIS T-scores in all domains: physical function (adjusted regression coefficient, -0.27; 95% confidence interval [CI], -0.39, -0.15), social participation (adjusted regression coefficient, -0.34; 95% CI, -0.50, -0.19), pain interference (adjusted regression coefficient, 0.49; 95% CI, 0.35, 0.64), sleep problems (adjusted regression coefficient, 0.29; 95% CI, 0.16, 0.43), fatigue (adjusted regression coefficient, 0.34; 95% CI, 0.18, 0.50), anxiety (adjusted regression coefficient, 0.23; 95% CI, 0.08, 0.38), and depression (adjusted regression coefficient, 0.20; 95% CI, 0.06, 0.35). Large-joint TSJD was associated with markedly worse PROs compared with small-joint TSJD. CONCLUSIONS: Elevated TSJD is associated with worse PROs particularly pain interference, social participation, and fatigue. Patients with more tender than swollen joints, especially large joints, may benefit from earlier, targeted therapeutic interventions.

Medical cannabis use by rheumatology patients in routine clinical care: results from The Ontario Best Practices Research Initiative.

OBJECTIVES: Medical cannabis is often used to alleviate common symptoms in patients with chronic conditions. With cannabis legalisation in Canada and easier access, it is important that rheumatologists understand its potential impact on their practice. Among patients attending rheumatology clinics in Ontario we assessed: the prevalence of medical cannabis use; symptoms treated; rheumatologists' perceptions. METHODS: Eight rheumatology clinics recruited consecutive adult patients in a 3-part medical cannabis survey: the first completed by rheumatologists; the second by all patients; the third by medical cannabis users. Student's t-test and Chi-square test were used to compare medical cannabis users to never users. RESULTS: 799 patients participated, 163 (20.4%) currently using medical cannabis or within <2 years and 636 never users; most had rheumatoid arthritis (37.8%) or osteoarthritis (34.0%). Compared to never users, current/past-users were younger; more likely to be taking opioids/anti-depressants, have psychiatric/gastrointestinal disorders, and have used recreational cannabis (p<0.05); had higher physician (2.9 vs. 2.1) and patient (6.0 vs. 4.2) global scores, and pain (6.2 vs. 4.7) (p<0.0001). Pain (95.5%), sleeping (82.3%) and anxiety (58.9%) were the most commonly treated symptoms; 78.2% of current/past-users reported medical cannabis was at least somewhat effective. Most rheumatologists reported being uncomfortable to authorise medical cannabis, primarily due to lack of evidence, knowledge, and product standardisation. CONCLUSIONS: Medical cannabis use among rheumatology patients in Ontario was two-fold higher than that reported for the general population of similar age. Use was associated with more severe disease, pain, and prior recreational use. Reported lack of research, knowledge, and product standardisation were barriers for rheumatologist use authorisation.

"From Where I Stand": using multiple anchors yields different benchmarks for meaningful improvement and worsening in the rheumatoid arthritis flare questionnaire (RA-FQ).

PURPOSE: The Rheumatoid Arthritis Flare Questionnaire (RA-FQ) is a patient-reported measure of disease activity in RA. We estimated minimal and meaningful change from the perspective of RA patients, physicians, and using a disease activity index. METHODS: Data were from 3- to 6-month visits of adults with early RA enrolled in the Canadian Early Arthritis Cohort. Participants completed the RA-FQ, the Patient Global Assessment of RA, and the Patient Global Change Impression at consecutive visits. Rheumatologists recorded joint counts and MD Global. Clinical Disease Activity Index (CDAI) scores were computed. We compared mean RA-FQ change across categories using patients, physicians, and CDAI anchors. RESULTS: The 808 adults were mostly white (84%) women (71%) with a mean age of 55 and moderate-high disease activity (85%) at enrollment. At V2, 79% of patients classified their RA as changed; 59% were better and 20% were worse. Patients reporting they were a lot worse had a mean RA-FQ increase of 8.9 points, whereas those who were a lot better had a -6.0 decrease. Minimal worsening and improvement were associated with a mean 4.7 and - 1.8 change in RA-FQ, respectively, while patients rating their RA unchanged had stable scores. Physician and CDAI classified more patients as worse than patients, and minimal and meaningful RA-FQ thresholds differed by group. CONCLUSION: Thresholds to identify meaningful change vary by anchor used. These data offer new evidence demonstrating robust psychometric properties of the RA-FQ and offer guidance about improvement or worsening, supporting its use in RA care, research, and decision-making.

Safety and therapeutic value of radiosynoviorthesis with yttrium-90: a Canadian single-centre experience.

BACKGROUND: Yttrium-90 (90Y) is approved in several countries as a radiosynoviorthesis agent in the intra-articular treatment of synovitis, however, no such radiopharmaceuticals are approved in Canada. The aim of this Health Canada-approved study was to examine the safety and efficacy of 90Y synovectomy among patients with refractory synovitis. METHODS: We performed a subset analysis of a prospective, phase III, single-arm, pan-Canadian trial. Large and medium-sized joints of adults with refractory inflammatory mono- or oligo-arthritis and minimal cartilage/bone destruction who failed treatment with two intra-articular corticosteroid injections were eligible. Patient follow-up was at 3, 6 and 12 months. Outcome measures included joint tenderness, swelling, effusion, joint function and bone scans. RESULTS: A total of 79 joints were included (90% knees). The underlying diagnosis included SpA (35.2% of patients), RA (26.8%), JIA (8.5%) and other (29.6%). Non-biologic DMARDs were concurrently used in 59.2% of patients and biologic/targeted synthetic DMARDs in 31%. Five adverse events occurred, including one serious radiation burn requiring surgery. All events were non-life-threatening and resolved. Significant improvements in joint tenderness, swelling and effusion were achieved at 3 months (P < 0.001), which were maintained until 12 months. During follow-up, 92.3% of joints did not show radiographic progression. Per the treating physician, clinically important improvement in joint function was observed in 90% of joints. CONCLUSION: Our results confirm the safety of 90Y radiosynoviorthesis in refractory synovitis and provide preliminary evidence supporting its clinical efficacy with sustained benefit at 12 months, suggesting that it is a safe alternative to surgical synovectomy in such cases. This is the first such study in a Canadian cohort.

The Scleroderma Patient-Centered Intervention Network Cohort: baseline clinical features and comparison with other large scleroderma cohorts.

Objectives: The Scleroderma Patient-centered Intervention Network (SPIN) Cohort is a web-based cohort designed to collect patient-reported outcomes at regular intervals as a framework for conducting trials of psychosocial, educational, self-management and rehabilitation interventions for patients with SSc. The aim of this study was to present baseline demographic, medical and patient-reported outcome data of the SPIN Cohort and to compare it with other large SSc cohorts. Methods: Descriptive statistics were used to summarize SPIN Cohort characteristics; these were compared with published data of the European Scleroderma Trials and Research (EUSTAR) and Canadian Scleroderma Research Group (CSRG) cohorts. Results: Demographic, organ involvement and antibody profile data for SPIN (N = 1125) were generally comparable with that of the EUSTAR (N = 7319) and CSRG (N = 1390) cohorts. There was a high proportion of women and White patients in all cohorts, though relative proportions differed. Scl70 antibody frequency was highest in EUSTAR, somewhat lower in SPIN, and lowest in CSRG, consistent with the higher proportion of interstitial lung disease among dcSSc patients in SPIN compared with in CSRG (48.5 vs 40.3%). RNA polymerase III antibody frequency was highest in SPIN and remarkably lower in EUSTAR (21.1 vs 2.4%), in line with the higher prevalence of SSc renal crisis (4.5 vs 2.1%) in SPIN. Conclusion: Although there are some differences, the SPIN Cohort is broadly comparable with other large prevalent SSc cohorts, increasing confidence that insights gained from the SPIN Cohort should be generalizable, although it should be noted that all three cohorts include primarily White participants.

Sirukumab for rheumatoid arthritis: the phase III SIRROUND-D study.

OBJECTIVES: Interleukin-6 (IL-6) is implicated in rheumatoid arthritis (RA) pathophysiology. Unlike IL-6 receptor inhibitors, sirukumab is a human monoclonal antibody that selectively binds to the IL-6 cytokine. The phase III, multicentre, randomised, double-blind, placebo-controlled, parallel-group SIRROUND-D study (ClinicalTrials.gov identifier NCT01604343) evaluated the efficacy and safety of sirukumab in patients with active RA refractory to disease-modifying antirheumatic drugs. METHODS: Patients were randomised 1:1:1 to treatment with sirukumab 100 mg every 2 weeks, 50 mg every 4 weeks or placebo every 2 weeks subcutaneously. Results through week 52 are reported. RESULTS: Of 1670 randomised patients, significantly more patients achieved American College of Rheumatology 20% (ACR20) response at week 16 (coprimary endpoint) with sirukumab 100 mg every 2 weeks (53.5%) or 50 mg every 4 weeks (54.8%) versus placebo (26.4%; both p<0.001). Mean (SD) change from baseline in modified Sharp/van der Heijde score at week 52 (coprimary endpoint) was significantly lower with sirukumab (100 mg every 2 weeks: 0.46 (3.26); 50 mg every 4 weeks: 0.50 (2.96)) versus placebo (3.69 (9.25); both p<0.001). All major secondary endpoints (week 24 Health Assessment Questionnaire-Disability Index change from baseline, ACR50 response, 28-joint Disease Activity Score based on C reactive protein and major clinical response (ACR70 for six continuous months by week 52)) were met. The most common adverse events with sirukumab were elevated liver enzymes, upper respiratory tract infection, injection site erythema and nasopharyngitis. CONCLUSIONS: Sirukumab 100 mg every 2 weeks and 50 mg every 4 weeks led to significant reductions in RA symptoms, inhibition of structural damage progression and physical function and quality of life improvements, with an expected safety profile. TRIAL REGISTRATION NUMBER: NCT01604343; Results.

Clinical correlates of faecal incontinence in systemic sclerosis: identifying therapeutic avenues.

Objectives: The aim was to establish the prevalence and severity of faecal incontinence (FI) in SSc, its association with other intestinal manifestations and potential predictors of FI, and its impact on quality of life. Methods: A multicentre, cross-sectional study of 298 SSc subjects followed in the Canadian Scleroderma Research Group cohort was performed using validated questionnaires: Jorge-Wexner score (an FI severity scale), Bristol stool scale (a visual scale of stool consistency) and FI Quality-of-Life scale. Constipation was defined by the Rome III criteria. Associations between the Jorge-Wexner score and other clinical variables were determined using multivariate regression analyses. Results: Eighty-one (27.2%) subjects had FI, which was mild in 37 (12.4%) and moderate to severe in 44 (14.8%). Most patients had well-formed stools, 111 (38.8%) reported constipation and 38 (13.4%) had been previously treated for small intestinal bacterial overgrowth (SIBO). Variables independently associated with FI were: loose vs well-formed stools [odds ratio (OR) = 7.01, 95% CI: 2.09, 23.51)], constipation (OR = 3.64, 95% CI: 1.61, 8.27, P = 0.002), history of SIBO (OR = 2.97, 95% CI: 1.06, 8.27) and urinary incontinence (OR = 2.45, 95% CI: 1.14, 5.27). Quality of life measured with the FI Quality-of-Life scale was inversely correlated with FI severity (correlation coefficients between -0.602 and -0.702, P < 0.001). Conclusion: FI was common and often severe in SSc. Loose stools, SIBO, constipation and urinary incontinence were strongly associated with FI. Other than targeting anorectal dysfunction, concomitant treatment of clinical correlates could lead to improvement in FI and quality of life in SSc.

The effect of rheumatoid arthritis-associated autoantibodies on the incidence of cardiovascular events in a large inception cohort of early inflammatory arthritis.

Objective: . RA is associated with an increased risk of cardiovascular events (CVEs). The objective was to estimate independent effects of RA autoantibodies on the incident CVEs in patients with early RA. Methods: Patients were enrolled in the Canadian Early Inflammatory Arthritis Cohort, a prospective multicentre inception cohort. Incident CVEs, including acute coronary syndromes and cerebrovascular events, were self-reported by the patient and partially validated by medical chart review. Seropositive status was defined as either RF or ACPA positive. Multivariable Cox proportional hazards survival analysis was used to estimate the effects of seropositive status on incident CVEs, controlling for RA clinical variables and traditional cardiovascular risk factors. Results: . A total of 2626 patients were included: the mean symptom duration at diagnosis was 6.3 months ( s . d . 4.6), the mean age was 53 years ( s . d . 15), 72% were female and 86% met classification criteria for RA. Forty-six incident CVEs occurred over 6483 person-years [incidence rate 7.1/1000 person-years (95% confidence interval 5.3, 9.4)]. The CVE rate did not differ in seropositive vs seronegative subjects and seropositivity was not associated with incident CVEs in multivariable Cox regression models. Baseline covariates independently associated with incident CVEs were older age, a history of hypertension and a longer duration of RA symptoms prior to diagnosis. Conclusion: The rate of CVEs early in the course of inflammatory arthritis was low; however, delays in the diagnosis of arthritis increased the rate of CVEs. Hypertension was the strongest independent risk factor for CVEs. Results support early aggressive management of RA disease activity and co-morbidities to prevent severe complications.

Treating rheumatoid arthritis to target: 2014 update of the recommendations of an international task force.

BACKGROUND: Reaching the therapeutic target of remission or low-disease activity has improved outcomes in patients with rheumatoid arthritis (RA) significantly. The treat-to-target recommendations, formulated in 2010, have provided a basis for implementation of a strategic approach towards this therapeutic goal in routine clinical practice, but these recommendations need to be re-evaluated for appropriateness and practicability in the light of new insights. OBJECTIVE: To update the 2010 treat-to-target recommendations based on systematic literature reviews (SLR) and expert opinion. METHODS: A task force of rheumatologists, patients and a nurse specialist assessed the SLR results and evaluated the individual items of the 2010 recommendations accordingly, reformulating many of the items. These were subsequently discussed, amended and voted upon by >40 experts, including 5 patients, from various regions of the world. Levels of evidence, strengths of recommendations and levels of agreement were derived. RESULTS: The update resulted in 4 overarching principles and 10 recommendations. The previous recommendations were partly adapted and their order changed as deemed appropriate in terms of importance in the view of the experts. The SLR had now provided also data for the effectiveness of targeting low-disease activity or remission in established rather than only early disease. The role of comorbidities, including their potential to preclude treatment intensification, was highlighted more strongly than before. The treatment aim was again defined as remission with low-disease activity being an alternative goal especially in patients with long-standing disease. Regular follow-up (every 1-3 months during active disease) with according therapeutic adaptations to reach the desired state was recommended. Follow-up examinations ought to employ composite measures of disease activity that include joint counts. Additional items provide further details for particular aspects of the disease, especially comorbidity and shared decision-making with the patient. Levels of evidence had increased for many items compared with the 2010 recommendations, and levels of agreement were very high for most of the individual recommendations (≥9/10). CONCLUSIONS: The 4 overarching principles and 10 recommendations are based on stronger evidence than before and are supposed to inform patients, rheumatologists and other stakeholders about strategies to reach optimal outcomes of RA.

Treatment preferences of patients with early rheumatoid arthritis: a discrete-choice experiment.

OBJECTIVE: To quantify the preferences of patients with early RA (ERA) with the benefits and harms of DMARDs. METHODS: We assessed patients' preferences using a discrete-choice experiment, an experimentally designed survey to measure trade-offs. Consecutive adult patients with ERA (<2 years since diagnosis) were presented 13 different sets of three treatment options described by eight attributes (clinical outcomes, risks and dosing regimens) and asked to choose one. From patients' responses we estimated the average importance of each attribute and explored preference heterogeneity through latent-class analysis. RESULTS: A total of 152 patients completed the survey (86% response rate): mean age 52 years, 63% female, disease duration 7.8 months. Treatment benefits (increasing the chance of a major symptom improvement and reducing the chance of serious joint damage) were most important. Of potential adverse events, a small risk of serious infections/possible increased risk of cancer was most important. Patients were willing to accept this risk for a 15% absolute increase in the chance of a major symptom improvement. Patients had an aversion to i.v. therapy, but were relatively indifferent to other dosing regimens. Through latent-class analysis, we identified two patient groups: 54% who were more risk averse, particularly to a possible risk of cancer/infection, and others who were highly benefit-driven. CONCLUSION: On average, patients with ERA were risk tolerant, but important differences in preferences were identified. In particular, a subgroup of patients may prefer to avoid treatments with a possible increased risk of cancer/infection if other effective options are available.

Self-reported comorbidity is common in early inflammatory arthritis and associated with poorer function and worse arthritis disease outcomes: results from the Canadian Early Arthritis Cohort.

OBJECTIVE: Comorbid medical conditions may influence treatment and contribute to poor outcomes in early RA. We aimed to assess the association of baseline comorbidity with outcomes in early inflammatory arthritis using data from the Canadian Early Arthritis Cohort. METHODS: Patients (n = 2090) with early inflammatory arthritis (symptom duration of < 1 year) reported comorbid medical conditions at baseline. Functional status (HAQ), detailed clinical assessments and treatment were assessed. Treatment is not protocolized but participating rheumatologists aim for remission. The influence of comorbidity on clinical outcomes was determined using multivariate models. RESULTS: At least one comorbid condition was reported by 76% of patients. Patients with comorbidity were older (mean age 56 vs 44 years, P < 0.0001) and had worse baseline function [median (interquartile range, IQR) HAQ score (0.88 (1) vs 0.75(1), P < 0.0001] compared with those without comorbidity even after controlling for age, sex and symptom duration. At 1 year, patients with baseline comorbidity were less likely to achieve remission (odds ratio, OR = 0.67; 95% CI: 0.51, 0.88, P = 0.004) and had higher HAQ [median (IQR) 0.25 (1) vs 0 (0), P < 0.0001] and pain scores [median (IQR) 2.85 (4) (out of 10) vs 1 (4), P < 0.0001] than patients without comorbidity after adjusting for age, sex, symptom duration, baseline disease activity and arthritis treatment. CONCLUSION: Comorbidity is common in early inflammatory arthritis and associated with higher disease activity, worse functional status and greater pain scores during the first year of follow-up. While the mechanisms for this association require investigation, addressing comorbidity may improve clinical outcomes in early RA.

Calcinosis is associated with digital ischaemia in systemic sclerosis-a longitudinal study.

OBJECTIVE: To determine if ischaemia is a causal factor in the development of calcinosis in SSc. METHODS: Patients with SSc were assessed yearly. Physicians reported the presence of calcinosis, digital ischaemia (digital ulcers, digital necrosis/gangrene, loss of digital pulp on any digits and/or auto- or surgical digital amputation) and nailfold capillary dropout assessed using a dermatoscope. The number of digits with digital ischaemia was used as an assessment of the severity of digital ischaemia. SSc specific antibodies were detected with a line immunoassay. Multiple logistic regression and Cox proportional hazards models were generated to determine associations between calcinosis, digital ischaemia and capillary dropout. RESULTS: One thousand three hundred and five patients were included in this study, of whom 300 (23.0%) had calcinosis at study entry. In a cross-sectional multivariate analysis, at baseline, calcinosis was associated with digital ischaemia (odds ratio (OR) = 2.37, 95% CI: 1.66, 3.39), severity of ischaemia (OR = 1.12, 95% CI: 1.06, 1.18), capillary dropout (OR = 1.41, 95% CI: 1.05, 1.89), ACAs (OR = 1.68, 95% CI: 1.17, 2.43) and anti-RNA polymerase III antibodies (OR = 1.77, 95% CI: 1.08, 2.89). Current use of calcium channel blockers was inversely associated with the presence of calcinosis (OR = 0.70, 95% CI: 0.52, 0.96). Of the 805 patients with no calcinosis at study entry and at least one follow-up visit, 215 (26.7%) developed calcinosis during follow-up. Significant baseline predictors of the development of calcinosis in follow-up were digital ischaemia (hazard ratio (HR) = 1.82, 95% CI: 1.30, 2.54), capillary dropout (HR = 1.46, 95% CI: 1.08, 1.99), dcSSc (HR = 1.57, 95% CI: 1.11, 2.21), ACA (HR = 2.18, 95% CI: 1.50, 3.17) and anti-RNA polymerase III antibodies (HR = 2.58, 95% CI: 1.65, 4.04). CONCLUSION: Ischaemia may play a role in the development of calcinosis in SSc.

The rapid kinetics of optimal treatment with subcutaneous methotrexate in early inflammatory arthritis: an observational study.

BACKGROUND: Methotrexate (MTX) is standard treatment for RA. Absorption is better in subcutaneous MTX (scMTX), which may impact speed of onset. In RA, earlier time to remission improves long-term results. Our objectives were to determine rapidity of response of subcutaneous methotrexate in early rheumatoid arthritis. METHODS: The change in several disease activity measures (including DAS28) from 0 to 6 weeks (early period) and 6 to 12 weeks (late period) was compared. The proportion achieving DAS28/CDAI/SDAI remission and/or low disease activity state was also compared. RESULTS: One hundred three patients were included from a single site between 2008 and 2014. All received MTX (98.0 % scMTX, 98 % 25 mg/week). There were no dropouts. There was a significantly greater early change in DAS28 (-1.9 vs. -0.2, p < 0.00); this effect was seen for several outcome measures. By 6 weeks, 59 % had achieved either DAS28 remission or low disease activity state, with 74 % achieving either state by 12 weeks. There were a larger proportion of patients achieving CDAI and DAS28 remission in the early versus late period (p < 0.0002 for both). There was significant improvement when using combination MTX and HCQ, however sample size was small (n = 9). The use of intra-articular steroids with MTX yielded the most disease measures that demonstrated early significant improvement. CONCLUSION: Subcutaneous MTX is rapid, as the change in many disease activity scores was significantly greater between 0-6 weeks compared to 6-12 weeks. Combination MTX + HCQ gave added value, although generalizability is limited by combination cohort sample size. Intra-articular steroid injections may contribute to the early effect.

Physician global assessment at 3 months is strongly predictive of remission at 12 months in early rheumatoid arthritis: results from the CATCH cohort.

OBJECTIVE: The objective of this study was to determine predictors of 1-year remission in early RA (ERA) using baseline and 3-month data. METHODS: The Canadian Early Arthritis Cohort (CATCH) patients were included if baseline, 3- and 12-month data were available. Regression analyses for four different definitions of remission at 12 months were done to determine baseline and 3-month predictors of remission. RESULTS: Five hundred and sixty-two patients had complete data at 12 months (mean age 53.4 years, disease duration 6.2 years, 73% female). The factors at baseline associated with all four remission outcomes at 12 months were age, gender, income, education, tender joint count (TJC), patient global assessment (PtGA), HAQ and pain. Baseline ESR was associated with the 28-joint DAS (DAS28) remission only. At 3 months, all four remission definitions were associated with TJC, swollen joint count, physician global assessment (PGA), PtGA, HAQ, pain, ESR and CRP in univariate analyses. In the regression model, variables associated with Simple Disease Activity Index remission were PGA [odds ratio (OR) 0.77, P < 0.001), pain (OR 0.85, P = 0.004), age (OR 0.98, P = 0.006) and HAQ (OR 0.49, P = 0.011); Clinical Disease Activity Index remission was associated with PGA (OR 0.77, P < 0.001), pain (OR 0.85, P = 0.003), age (OR 0.98, P = 0.015) and CRP (OR 0.80, P = 0.031). DAS28 remission was predicted by ESR (OR 0.95, P < 0.001), PGA (OR 0.76, P < 0.001), age (OR 0.98, P = 0.001), HAQ (OR 0.57, P = 0.006) and male gender (OR 2.01, P = 0.005), whereas Boolean remission was associated with pain (OR 0.79, P = 0.009), age (OR 0.98, P = 0.016), PtGA (OR 0.83, P = 0.025) and PGA (OR 0.86, P = 0.038). CONCLUSION: A low PGA at 3 months was consistently associated with 1-year remission in ERA.

Are there differences between young- and older-onset early inflammatory arthritis and do these impact outcomes? An analysis from the CATCH cohort.

OBJECTIVE: The aim of this study was to determine the impact of age on disease and remission in suspected early RA (ERA). METHODS: Data from the Canadian Early Arthritis Cohort (CATCH) were examined at baseline, 6 and 12 months. Patients were divided into three groups based on age. Analysis of variance (ANOVA) and regression models were performed to determine the impact of age on the 28-joint DAS (DAS28) and remission at 12 months. RESULTS: A total of 1809 patients were initially assessed: 442 (24.4%) young (<42 years), 899 (49.7%) middleaged (542<64 years) and 468 (25.9%) old (564 years); 72.9% female; 63.8% met 2010 ACR/European League Against Rheumatism (EULAR) classification criteria for RA; symptom duration at first visit 186.0 days; DAS28 4.9; HAQ 1.0; 25.3% had baseline erosions. A significant correlation existed between older age and a lower percentage of females, less positive RF and CCP, fewer meeting RA criteria, shorter symptom duration, more erosions at first visit, higher DAS28 and HAQ at baseline and 12 months and fewer DAS28 remission at 12 months (all P<0.003). The age group did not affect the change in DAS28 and HAQ from 0 to 12 months. Co-morbidities increased with age; more DMARDs, including MTX and steroids, and fewer biologics were used in older age. Age and female had a lesser chance of remission in the regression model. CONCLUSION: In suspected ERA, older-onset patients start and end their first year worse in terms of DAS28 and HAQ, with fewer meeting RA criteria, less remission, more DMARDs and steroids use but less biologics use. However, there were no differences between age groups in the change in DAS28.

A training program designed to improve interprofessional knowledge, skills and attitudes in chronic disease settings.

For over 25 years, The Arthritis Program (TAP) at Southlake Regional Health Centre has worked within a successful interprofessional model. TAP recognized the need to teach its model and developed The Arthritis Program - Interprofessional Training Program (TAP-ITP). This pilot study evaluated perceptions of 22 TAP-ITP participants related to effectiveness and satisfaction. The study employed a longitudinal survey design and data were collected at the baseline (T1), post-program (T2), and at one year (T3) by use of the following instruments: W(e)Learn Program Assessment; Interprofessional (IP) Learner and Team Contracts; Interprofessional Collaborative Competencies Attainment Survey (ICCAS); Bruyère Clinical Team Self Assessment Scale; and Attitudes Toward Health Care Teams (ATHCT). Data analysis included descriptive, non-parametric and parametric tests. Results indicated participants were very satisfied with TAP-ITP. ICCAS scores revealed statistically significant differences (Wilcoxon rank sum tests) from T1 to T2 in perceptions of IPC competencies (p < 0.05). Paired t-tests for each T1 to post (T2 and T3) scores were all significant (p < 0.05) for each Bruyère subscale and overall scores. For ATHCT, paired t-tests for each T1 to T2 were significant for Quality of Care/Process (p = 0.04) and borderline significant for Physician Centrality scale (p = 0.06). At T3, improvement in both scales was maintained. This pilot study suggests that TAP-ITP improves self-assessed scores of knowledge and skills, as well as attitudes in interprofessional care post-program and sustained at one year.

Treating rheumatoid arthritis to target: a Canadian patient survey.

BACKGROUND: Recently, many countries, including Canada, evaluated rheumatologists' acceptance and agreement with a set of 10 Treat to Target (T2T) recommendations for rheumatoid arthritis (RA), developed by an international task force. In this study, the Canadian T2T steering committee evaluated how Canadian patients with RA perceive these recommendations. OBJECTIVES: The objectives of this study were to assess the current state of RA management in Canada from a patient perspective and to assess whether and to what extent Canadians with RA agree with each of the 10 T2T recommendations and to compare the results with a previous survey completed by physicians. METHODS: Participating rheumatologists were asked to invite consecutive RA patients to complete a 20-question survey. The survey was designed to assess relevant sociodemographic variables, the current treatment, and the approach to RA management as seen from the patient's perspective, as well as their agreement with the T2T recommendations. RESULTS: A total of 959 patients (77% were female) were recruited by 22 participating rheumatologists from 6 Canadian provinces. Patients had a mean age of 59.1 years and mean disease duration of 12.9 years. Approximately 72% of patients were on methotrexate (76.1% combination therapy), and 36.7% were treated with biologics (6.4% monotherapy, 30.3% combination therapy). The agreement with T2T recommendations ranged from 8.6 for recommendation 4 (frequency of adjustment of drug therapy) to 9.5 for recommendation 8 (maintenance of treatment targets). These results are comparable to a previous physicians' survey except that there was more acceptance on the part of patients for more frequent visits (recommendation 5; patient agreement score was 9.06 vs physician agreement score of 6.92) and evaluations for adjustments of therapy (recommendation 6 patient agreement score was 9.39 vs physician agreement score of 7.49) to achieve the stated goal. CONCLUSIONS: The results of this survey showed that Canadian patients are being treated for their RA according to the published treatment recommendations with combination disease-modifying antirheumatic drugs and biologics and a small percentage with oral corticosteroids. The majority of patients seems to be satisfied with their management and is in agreement with the T2T recommendations, although they tended to place greater emphasis than did physicians on flexibility of visit frequency and detailed assessments.

Use of Apremilast to Achieve Psoriatic Arthritis Treatment Goals and Satisfaction at 1 Year in the Canadian Real-World APPRAISE Study.

INTRODUCTION: The APPRAISE study was conducted to better understand the 12-month effectiveness, tolerability, and patient satisfaction with apremilast treatment for patients with psoriatic arthritis (PsA) in real-world settings. METHODS: APPRAISE (NCT03608657), a prospective, multicenter, observational study, enrolled adults with active PsA prescribed apremilast per routine care between July 2018 and March 2020. Patients were followed for 12 months with visits suggested every 4 months. The primary outcome measure was achievement of remission (REM) or low disease activity (LDA), defined as a Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) score ≤ 13. RESULTS: Of the 102 patients who enrolled, 45 (44.1%) discontinued the study by 12 months. Most patients (75.5%) had moderate or high disease activity, and 24.5% were in REM/LDA at baseline based on cDAPSA score. Achievement of cDAPSA REM/LDA was 63.7%, 67.2%, and 53.8% at months 4, 8, and 12, respectively. In those continuing in the study, significant improvements were seen in swollen and tender joint counts, pain visual analog scale, psoriasis body surface area, and complete dactylitis resolution. Enthesitis reduction was also observed. Improvements in treatment satisfaction and patient-reported outcomes, including Health Assessment Questionnaire-Disability Index and the 36-item Short Form physical and mental component scores, were observed over 12 months. The proportion of patients achieving a Patient-Acceptable Symptom State (PASS) increased significantly from baseline at months 4, 8, and 12 (P < 0.001). Apremilast was well tolerated; the most frequent adverse events (AEs) leading to discontinuation were diarrhea (9/102 [8.8%]), nausea (4/102 [3.9%]), and migraine (4/102 [3.9%]). CONCLUSION: In this real-world study conducted in Canadian rheumatology clinics, apremilast demonstrated clinical effectiveness in patients with active PsA, along with patient satisfaction with treatment. Safety findings were consistent with previously reported clinical data. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03608657.

Having More Tender Than Swollen Joints is Associated With Worse Function and Work Impairment in Patients With Early Rheumatoid Arthritis.

OBJECTIVE: Patients with early rheumatoid arthritis (RA) may present with more tender than swollen joints, which can persist. Elevated tender-swollen joint difference (TSJD) is often challenging, because there may be multiple causes and it may contribute to overestimating disease activity. Little is known about the phenotype and impact of TSJDs on patient function. Our objective was to evaluate the impact of TSJD on functional outcomes in early RA and to see whether associations vary by joint size. METHODS: Data were from patients with active, early RA (≤12 months) enrolled in the Canadian Early Arthritis Cohort, who completed assessments of general function (Multidimensional Health Assessment Questionnaire [MDHAQ]), upper extremity (UE) function (Quality of Life in Neurological Disorders [Neuro-QoL] UE scale), and work/activity impairment (Work Productivity and Activity Impairment RA) over their first year of follow-up. A total of 28 joint counts were performed. TSJDs were calculated. Adjusted associations between TSJDs and functional outcomes were estimated in separate multivariable linear mixed effects models. Separate analyses were performed for large- versus small-joint TSJD. RESULTS: Patients (N = 547) were 70% female, mean age 56 (SD 15) years, mean disease duration 5.3 (SD 2.9) months. At baseline, 287 (52%) had TSJD >0 (43% involved large joints and 34% small joints), decreasing to 32% at 12 months. A one-point increase in TSJD was significantly associated with worse function (MDHAQ: adjusted mean change 0.10, 95% confidence interval [CI] 0.08-0.13; Neuro-QoL UE function T score: adjusted mean change -0.59, 95% CI -0.76 to -0.43; and greater work impairment: adjusted mean change 1.95%, 95% CI 0.85%-3.05%). Higher large-joint TSJDs were associated with the worst functional outcomes. CONCLUSION: Having more tender than swollen joints is common in early RA and is associated with worse function, most notably when involving large joints. Early identification and targeted intervention strategies may be needed.

Risk factors for prevalent and incident hypertension in rheumatoid arthritis: data from the Canadian Early Arthritis Cohort.

Objective: Hypertension (HTN) is a common comorbidity in RA. This study aimed to explore the prevalence and incidence of HTN and baseline factors associated with incident HTN in early RA (ERA). Methods: Data were from the Canadian Early Arthritis Cohort (CATCH), an inception cohort of ERA patients having <1 year of disease duration. HTN was determined by patient- or physician-reported diagnosis, the use of anti-hypertensives and/or blood pressure. Multivariable logistic regression was performed to determine baseline factors associated with prevalent and incident HTN in this population. Results: The study sample included 2052 ERA patients [mean age 55 years (s.d. 14), 71% female). The prevalence of HTN at study enrolment was 26% (23% in females and 34% in males). In both sexes, prevalent HTN was associated with older age, diabetes and hyperlipidaemia. HTN was associated with being overweight or high alcohol consumption in females. Of the RA patients who did not have HTN at enrolment, 24% (364/1518) developed HTN during the median follow-up period of 5 years (range 1-8). Baseline factors significantly associated with incident HTN were older age, being overweight, excess alcohol consumption and having hyperlipidaemia. Incident HTN was associated with high alcohol consumption in males and with hyperlipidaemia in females. RA-associated disease factors and treatments were not significantly associated with prevalent or incident HTN. Conclusions: Early RA patients had a high incidence of hypertension with the highest risk in older patients with traditional cardiovascular risk factors.
