Automated Text Message-Enhanced Monitoring Versus Routine Monitoring in Early Rheumatoid Arthritis: A Randomized Trial.

OBJECTIVE: Frequent monitoring of patients with early rheumatoid arthritis (RA) is required for achieving good outcomes. This study was undertaken to investigate the influence of text message (SMS)-enhanced monitoring on early RA outcomes. METHODS: We randomized 166 patients with early, disease-modifying antirheumatic drug-naive RA to receive SMS-enhanced follow-up or routine care. All patients attended visits at 0, 3, and 6 months, and a follow-up visit at 12 months. Treatment was at the physicians' discretion. The intervention included 13 SMSs during weeks 0-24 with questions concerning medication problems (yes/no) and disease activity (patient global assessment [PtGA], scale 0-10). Patients were contacted if response SMSs indicated medication problems or PtGA exceeded predefined thresholds. Primary outcome was 6-month Boolean remission (no swollen or tender joints and normal C-reactive protein levels). Quality of life (QoL; measured by the Short Form 36 survey) and Disease Activity Score in 28 joints (DAS28) were assessed. RESULTS: Six and 12-month follow-up data were available for 162 and 157 patients, respectively. In the intervention group, 46% of the patients (38 of 82) reported medication problems and 49% (40 of 82) reported text message PtGAs above the alarm limit. Remission rates at 6 months (P = 0.34) were 51% in the intervention group and 42% in the control group. These rates were 57% and 43% at 12 months (P = 0.17) in the intervention and control groups, respectively. The respective mean ± SD DAS28 scores for the intervention and control groups were 1.92 ± 1.12 and 2.22 ± 1.11 at 6 months (P = 0.09); and 1.79 ± 0.91 and 2.08 ± 1.22 at 12 months (P = 0.28). No differences in QoL were observed. CONCLUSION: The study did not meet the primary outcome despite a trend favoring the intervention group. This may be explained by the notably high overall remission rates.

Cervical Spine Involvement among Patients with Rheumatoid Arthritis Treated Actively with Treat-to-target Strategy: 10-year Results of the NEO-RACo Study.

OBJECTIVE: To evaluate the development of radiological changes of the cervical spine in patients with rheumatoid arthritis (RA) in the NEO-RACo trial treated with an intensive, remission-targeted combination of conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and additional infliximab (IFX) or placebo (PLA) for the first 6 months. METHODS: Ninety-nine patients with early, DMARD-naive RA were treated with a triple combination of csDMARD and prednisolone, and randomized to double-blindly receive either IFX (FIN-RACo+IFX) or PLA (FIN-RACo+PLA) infusions during the first 6 months. After 2 years the treatment strategies became unrestricted, but the treatment goal was strict NEO-RACo remission. At the 10-year visit, radiographs of the cervical spine were taken of 85 patients (38 in the FIN-RACo+IFX group and 47 in the FIN-RACo+PLA group). The study was registered at ClinicalTrials.gov (NCT00908089). RESULTS: There were 4/85 patients (4.7%) with cervical spine involvement (CSI) by 10 years. Atlantoaxial subluxation was found in 2/85 patients (2.4%), both in the FIN-RACo+IFX group, and none in the FIN-RACo+PLA group. Atlantoaxial impaction was found in 1/85 patients (1.2%) in the FIN-RACo+IFX group. Subaxial subluxation was found in 1/85 patients (1.2%). CONCLUSION: Early and intensive remission-targeted treatment has reduced the incidence of CSI and our results show that intensive treatment also prevents its development in the long run.

Early Targeted Combination Treatment With Conventional Synthetic Disease-Modifying Antirheumatic Drugs and Long-Term Outcomes in Rheumatoid Arthritis: Ten-Year Follow-Up Results of a Randomized Clinical Trial.

OBJECTIVE: The short-term outcomes of remission-targeted treatments of rheumatoid arthritis (RA) are well-established, but the long-term success of such strategies is speculative, as is the role of early add-on biologics. We assessed the 10-year outcomes of patients with early RA treated with initial remission-targeted triple combination of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), 7.5-mg prednisolone, and additional infliximab (IFX) or placebo infusions. METHODS: Ninety-nine patients with early, DMARD-naive RA were treated with a triple combination of csDMARDs and prednisolone and randomized to double-blind receipt of infusions of either IFX (the Finnish Rheumatoid Arthritis Combination Therapy Trial [FIN-RACo] + IFX) or placebo (FIN-RACo + placebo) during the first 6 months. After 2 years, the treatment strategies became unrestricted, but the treatment goal was strict remission in the TNF-Blocking Therapy in Combination With Disease-Modifying Antirheumatic Drugs in Early Rheumatoid Arthritis (NEO-RACo) study. At 10 years, the clinical and radiographic outcomes and the drug treatments used between 5 and 10 years were assessed. RESULTS: Ninety patients (91%) were followed after 2 years, 43 in the FIN-RACo + IFX and 47 in the FIN-RACo + placebo group. At 10 years, the respective proportions of patients in strict NEO-RACo remission and in Disease Activity Score using 28 joints remission in the FIN-RACo + IFX and FIN-RACo + placebo groups were 46% and 38% (P = 0.46) and 82% and 72% (P = 0.29), respectively. The mean total Sharp/van der Heijde score was 9.8 in the FIN-RACo + IFX and 7.3 in the FIN-RACo + placebo group (P = 0.34). During the 10-year follow-up, 26% of the FIN-RACo + IFX group and 30% of the FIN-RACo + placebo group had received biologics (P = 0.74). CONCLUSION: In early RA, excellent results can be maintained up until 10 years in most patients treated with initial combination csDMARDs and remission-targeted strategy, regardless of initial IFX/placebo infusions.

Decreasing muscle performance associated with increasing disease activity in patients with rheumatoid arthritis.

OBJECTIVES: Increasing evidence suggests that inflammation has a detrimental effect on muscle strength. Our objective was to analyse the association between muscle performance and different disease activity levels in patients with rheumatoid arthritis (RA). METHOD: A total of 199 consecutive outpatients were subject to cross-sectional assessment. Measurements of grip strength, endurance of the upper and lower limbs and trunk strength were combined as a muscle performance composite score (MPCS), using a standardised method. The disease activity for 28 joints (DAS28), radiographs of small joints (Larsen score), rheumatoid factor, body mass index (BMI), comorbidities and anti-rheumatic drugs were verified. Patients' questionnaires included sociodemographic information, pain level, global disease activity, the Beck Depression Inventory, the mental and physical component scores of Short Form-36 and physical activity level. RESULTS: Of the 199 patients, 36%, 17% and 47% patients had remission, low/moderate and high DAS28, respectively. The patients in remission had significantly shorter disease duration, better parameters in terms of pain, physician's assessment, Larsen, Beck or physical component score of Short Form-36, and they were more physically active than other patients. After adjustments for age, sex, RA duration, radiographs and BMI, the decreasing MPCS associated linearly with the increasing DAS28 activity levels (linearity, P <0.001). CONCLUSION: Poorer MPCS is clearly associated with higher disease activity in patients with RA. Muscle performance is a modifiable risk factor. The findings suggest evaluating muscle performance in clinical practice as a part of patient care.

Glycoprotein YKL-40: A potential biomarker of disease activity in rheumatoid arthritis during intensive treatment with csDMARDs and infliximab. Evidence from the randomised controlled NEO-RACo trial.

OBJECTIVE: YKL-40, a chitinase-like glycoprotein associated with inflammation and tissue remodeling, is produced by joint tissues and recognized as a candidate auto-antigen in rheumatoid arthritis (RA). In the present study, we investigated YKL-40 as a potential biomarker of disease activity in patients with early RA at baseline and during intensive treatment aiming for early remission. METHODS: Ninety-nine patients with early DMARD-naïve RA participated in the NEO-RACo study. For the first four weeks, the patients were treated with the combination of sulphasalazine, methotrexate, hydroxychloroquine and low dose prednisolone (FIN-RACo DMARD combination), and subsequently randomized to receive placebo or infliximab added on the treatment for further 22 weeks. Disease activity was evaluated using the 28-joint disease activity score and plasma YKL-40 concentrations were measured by immunoassay. RESULTS: At the baseline, plasma YKL-40 concentration was 57 ± 37 (mean ± SD) ng/ml. YKL-40 was significantly associated with the disease activity score, interleukin-6 and erythrocyte sedimentation rate both at the baseline and during the 26 weeks' treatment. The csDMARD combination decreased YKL-40 levels already during the first four weeks of treatment, and there was no further reduction when the tumour necrosis factor-α antagonist infliximab was added on the combination treatment. CONCLUSIONS: High YKL-40 levels were found to be associated with disease activity in early DMARD-naïve RA and during intensive treat-to-target therapy. The present results suggest YKL-40 as a useful biomarker of disease activity in RA to be used to steer treatment towards remission.

Effectiveness and drug survival of TNF-inhibitors in the treatment of psoriatic arthritis: A prospective cohort study.

BACKGROUND AND OBJECTIVES: Tumor necrosis factor (TNF)-inhibitors are used to treat psoriatic arthritis (PsA), but only a limited number of observational studies on this subject have been published thus far. The aim of this research was to analyze the effectiveness and drug survival of TNF-inhibitors in the treatment of PsA. METHODS: PsA patients identified from the National Register for Biologic Treatment in Finland (ROB-FIN) starting their first, second, or third TNF-inhibitor treatment between 2004 and 2014 were included. Effectiveness was measured using ACR and EULAR response criteria and modeled using ordinal logistic regression. Treatment persistence was analyzed using Kaplan-Meier survival analysis and Cox proportional hazards model. RESULTS: The study comprised 765 patients and 990 TNF-inhibitor treatment courses. EULAR moderate treatment responses at 6 months were achieved by 68% and 37% of the users of the first and the second or the third biologic, respectively. The probabilities of discontinuing the treatment within 12 and 24 months were 20% and 28%, respectively. Adjusted treatment responses to all TNF-inhibitors were similar; however, co-therapy with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) was not associated with better effectiveness. Adalimumab [hazard ratio (HR) = 0.62; 95% confidence interval (CI): 0.44-0.88] was superior to infliximab in drug survival while etanercept (HR = 0.77, 95% CI: 0.55-1.1) and golimumab (HR = 0.75, 95% CI: 0.46-1.2) did not differ from it. Co-medication with csDMARDs did not statistically improve drug survival. CONCLUSION: All available TNF-inhibitors showed similar treatment responses with or without csDMARDs. Adalimumab was associated with better drug survival when compared to infliximab.

Failure in longterm treatment is rare in actively treated patients with rheumatoid arthritis, but may be predicted by high health assessment score at baseline and by residual disease activity at 3 and 6 months: the 5-year followup results of the randomized clinical NEO-RACo trial.

OBJECTIVE: With modern initial aggressive combination treatments with synthetic disease-modifying antirheumatic drugs (sDMARD), most patients with rheumatoid arthritis (RA) achieve remission, have marginal radiographic progression, and sustain normal function. Here we aim to identify the patients failing these targets even after aggressive treatment. METHODS: Ninety-nine patients with early, active RA were treated with a combination of 3 sDMARD and prednisolone (PRD), and either infliximab or placebo infusions during the first 6 months, aiming at strict remission. After 24 months, the treatments became unrestricted. At 60 months, 4 evident clinical features of treatment failure were defined: area under curve (AUC) between 6-60 months for disease activity score assessing 28 joints > 2.6; AUC 6-60 for health assessment questionnaire > 0.5; progression in total Sharp/van der Heijde score 0-60 months > 3 units; and need of PRD or biologic DMARD treatment at 60 months. RESULTS: A total of 93 patients were followed up for 60 months. Of them, 45 had no features of treatment failure, 30 had 1, 10 had 2, 7 had 3, and 1 patient had all 4 features. Having 2-4 features of treatment failure at 5 years was predicted by the health assessment score at baseline, and by even low residual disease activity at 3 and 6 months. CONCLUSIONS: Only 20% of the patients with RA treated early with combination sDMARD and PRD have more than 1 clinical feature of treatment failure at 60 months. Residual clinical disease activity at 3-6 months was the most important predictor for identifying these patients. The study was registered at www.clintrials.gov (NCT00908089).

Infliximab for 6 months added on combination therapy in early rheumatoid arthritis: 2-year results from an investigator-initiated, randomised, double-blind, placebo-controlled study (the NEO-RACo Study).

OBJECTIVE: Early treatment of patients with rheumatoid arthritis (RA) with combination treatment starting with methotrexate, sulfasalazine, hydroxychloroquine and prednisolone (FIN-RACo strategy) is superior to monotherapy. A study was undertaken to determine whether infliximab (INFL) added to intensified FIN-RACo treatment for the initial 6 months improves the 2-year outcome. METHODS: 99 patients with early untreated active RA were enrolled in an investigator-initiated, randomised, double-blind, multicentre, parallel-group trial. Primary outcomes were remission and radiological changes at 2 years. All patients started with FIN-RACo. In addition, they were randomised to receive INFL or placebo (Pla) from weeks 4 to 26. RESULTS: At 24 months, 66% and 53%, respectively, of the patients in the FIN-RACo+INFL and FIN-RACo+Pla groups were in remission according to the modified American College of Rheumatology (ACR) criteria (p=0.19), 26% and 10% were in sustained modified ACR remission (p=0.042) and 82% in both groups were in remission by 28-joint disease activity score (not significant). Mean changes in the total Sharp-van der Heijde score were 0.2 and 1.4, respectively (p=0.0058). CONCLUSIONS: Most patients with early active RA achieve clinical remission and develop negligible joint damage with the intensified FIN-RACo regimen. Adding INFL for the first 6 months delays radiological progression.

Sustained improvement of health-related quality of life in patients with early rheumatoid arthritis: a ten-year follow-up study.

OBJECTIVES: To assess long-term impact of RA on the HR-QoL in a cohort of working-age patients with early disease treated by a multidisciplinary team including early and active use of disease-modifying anti-rheumatic drugs (DMARDs). METHODS: Fifty-five consecutive patients with RA who were naïve to DMARDs and glucocorticoids were assessed at baseline and at 6 months, 1, 2, 5 and 10 years. HR-QoL, disease activity, function, and joint destruction of hands and feet were assessed by using the Nottingham Health Profile (NHP) instrument, the 28-joint based Disease Activity Score (DAS28), the Health Assessment Questionnaire (HAQ), and the Larsen scores, respectively. GEE (generalised estimation equations)-method was used to evaluate longitudinal relationships between the HR-QoL changes and other variables. RESULTS: All NHP dimensions except social isolation improved significantly during the first six months and remained favourable up to 10 years. The most prominent improvements were seen in the dimensions for pain and emotional reaction (p<0.001). In longitudinal evaluation statistically significant associations (p<0.001) were found between the DAS28 and the NHP dimensions for pain, energy and emotional reaction, and between the HAQ and the NHP dimensions for pain, energy and mobility. The extent of joint damage had no statistically significant associations to the six dimensions of the NHP instrument. CONCLUSIONS: Early improvements in HR-QoL carried over the ten-year follow-up in patients with recent-onset RA treated with a multidisciplinary strategy including early and active DMARD therapy. HR-QoL changes were longitudinally associated especially with disease activity and function.

Effectiveness of anakinra in rheumatic disease in patients naive to biological drugs or previously on TNF blocking drugs: an observational study.

The aim of this study was to evaluate the effectiveness of IL-1 inhibition in rheumatic disease using real-life, observational methods. We analyzed data from 47 patients collected from the national ROB-FIN for rheumatic disease. Commonly used, validated measures of efficacy and adverse effects were documented and analyzed. The series contains 47/1,135 patients (mean age 47+/-11 years, range 25-73, females 83%) on anakinra of whom 39 patients suffered from rheumatoid arthritis (RA), two presented with psoriatic arthritis, and four with juvenile RA. At 3 months (26/40), 46% reached American College of Rheumatology (ACR) 20 and 27% ACR 50. In patients naive to biological drugs, the response rate at 3 months was 60% for ACR 20 and 20% for ACR 50. At follow-up of the total series, ACR responses at 6 and 12 months were 69/56% for ACR 20 and 23/22% for ACR 50. These data give room for IL-1 suppression when treating patient with rheumatic disease. Careful selection of patients, together with combining anakinra with disease-modifying antirheumatic drugs, perhaps adds effectiveness. For treating clinicians in Finland, these results are encouraging, as reimbursed treatment alternatives for patients refractory to all other therapies are still few.

Evaluation of the MDHAQ in Finnish patients with RA [corrected].

OBJECTIVE: To study the characteristics of the Multidimensional Health Assessment Questionnaire (MDHAQ) in Finnish patients with rheumatoid arthritis. METHODS: The reliability of the questionnaire was tested by test-retest procedure. Construct validity was studied by factor analysis and convergent validity by calculating correlations between the Finnish MDHAQ (Finn-MDHAQ) scales and the Finnish Health Assessment Questionnaire (HAQ) and the Finnish Arthritis Impact Measurement Scales (Finn-AIMS2). Correlations between Finn-MDHAQ and measures of clinical characteristics, disease activity, and functional class were also measured. An item analysis was made of the Finn-MDHAQ scales Function (FN) and Psychological (PS). RESULTS: Internal consistency on the FN scale was 0.92 (95% lower limit 0.89) and 0.66 (0.56) on the PS scale. Reproducibility (95% CI) on FN was 0.93 (0.82 to 0.97) and on PS 0.84 (0.70 to 0.92). Factor analysis identified 2 factors, mobility of upper extremities and trunk, and mobility of lower extremities. Strong correlations were found between the FN scale and HAQ and physical subscales of Finn-AIMS2 and between PS and the psychological subscales of Finn-AIMS2. In item analysis corrected item correlation was high on the Finn-MDHAQ scales, except in one item on the PS scale. CONCLUSION: The Finn-MDHAQ is an applicable, reliable, and valid instrument for the part of the FN scale measuring functional ability in Finnish rheumatic patients. The incongruity in the PS scale structure that produced moderate internal consistency can be overcome with minor modifications.
