ABSTRACT

OBJECTIVE: Treat-to-target (T2T) leads to improved clinical outcomes in early rheumatoid arthritis (RA). The question is whether these results sustain in the long term. Our objective was to investigate the 3-year results of a protocolized T2T strategy in daily clinical practice. METHODS: In the Dutch Rheumatoid Arthritis Monitoring remission induction cohort, patients newly diagnosed with RA were treated according to a T2T strategy aimed at remission (Disease Activity Score in 28 joints [DAS28] <2.6). Patients were treated with methotrexate, followed by the addition of sulfasalazine, and exchange of sulfasalazine with anti-tumor necrosis factor α agents in case of failure. Primary outcomes were disease activity, Health Assessment Questionnaire (HAQ) score, Short Form 36 physical component summary (PCS) and mental component summary (MCS) scores, and the Sharp/van der Heijde score (SHS) after 3 years. Secondary outcomes were sustained DAS28 remission (≥6 months) and remission according to the provisional American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) definition. RESULTS: After 3 years (n = 342), 61.7% of patients were in DAS28 remission and 25.3% met the provisional ACR/EULAR definition of remission. Sustained remission was experienced by 70.5%, which in the majority was achieved with conventional disease-modifying antirheumatic drugs only. The median scores were 0.4 (interquartile range [IQR] 0.0-1.0) for the HAQ, 45.0 (IQR 38.4-53.2) for the PCS, 53.1 (IQR 43.2-60.8) for the MCS, and 6.0 (IQR 3.0-13.0) for the total SHS. CONCLUSION: In very early RA, T2T leads to high (sustained) remission rates, improved physical function and health-related quality of life, and limited radiographic damage after 3 years in daily clinical practice.

ABSTRACT

Previously reported data on 5 computer-based programs for measurement of joint space width focusing on discriminating ability and reproducibility are updated, showing new data. Four of 5 different programs for measuring joint space width were more discriminating than observer scoring for change in narrowing in the 12 months interval. Three of 4 programs were more discriminating than observer scoring for the 0-18 month interval. The program that failed to discriminate in the 0-12 month interval was not the same program that failed in the 0-18 month interval. The committee agreed at an interim meeting in November 2007 that an important goal for computer-based measurement programs is a 90% success rate in making measurements of joint pairs in followup studies. This means that the same joint must be measured in images of both timepoints in order to assess change over time in serial radiographs. None of the programs met this 90% threshold, but 3 programs achieved 85%-90% success rate. Intraclass correlation coefficients for assessing change in joint space width in individual joints were 0.98 or 0.99 for 4 programs. The smallest detectable change was < 0.2 mm for 4 of the 5 programs, representing 29%-36% of the change within the 99th percentile of measurements.
