Abstract

Background Early and aggressive targeted treatment with disease modifying anti-rheumatic drugs (DMARDs) has been shown to lead to substantial reductions in disease activity (1,2) and radiologic damage in patients with early rheumatoid arthritis (RA) (3,4).

Objectives The aim of this study was to compare the first-year radiographic progression rates between a treat-to-target (T2T) strategy with initial combination therapy (strategy II) versus an initial step-up monotherapy (strategy I).

Methods A total of 128 patients from strategy II was individually matched with 128 patients from strategy I on sex, age (± 5 yrs.) and baseline disease activity (± 0.5 on the DAS28). Differences in radiographic progression scores and the number of patients experiencing a minimal clinically important difference (≥5 SHS points; MCID) between both strategies were tested with Mann Whitney U test and chi-square test. Next, linear and logistic regression analyses were performed to examine which baseline variables were associated with radiographic progression scores and the probability of experiencing an MCID within 1 year.

Results Patients with initial combination therapy had slightly higher baseline disease activity scores and pain scores, but better mental health scores. Patients with initial monotherapy had significantly more, and more frequently clinically relevant, radiographic progression after one year. Experiencing a MCID was associated with fewer tender joints (p=0.05) and higher ESR (p=0.02) at baseline.

Conclusions Excellent radiographic outcome was achieved for patients treated according to a protocolled T2T strategy in daily clinical practice. Patients treated with initial monotherapy had significantly more short-term radiographic progression than patients treated with initial combination therapy.
