Objectives: To provide a survey of disease activity in patients treated with standard care in Italian clinical practice.
Methods: This was an observational prospective cohort study in patients with early, aggressive rheumatoid arthritis (RA; duration ≤2 years but ≥6 weeks; DAS28 >3.2) naïve to anti-tumour necrosis factor (TNF) therapy who were treated with disease-modifying anti-rheumatic drugs (DMARDs) and/or biologics according to standard practice at 15 Italian ARPA (Artrite Reumatoide Precoce Aggressiva) centres. Patients were evaluated at baseline and after 6, 12 and 24 months. The primary endpoint was the proportion of patients achieving remission, as defined by disease activity score in 28 joints (DAS28) <2.6, after 1 year.
Results: Among the 152 patients enrolled, 92 were evaluable after 1 year and 77 after 2 years for DAS28. At baseline, patients had a mean DAS28 of 6.1±1.0. At 12 months, 62.6% of patients were treated with DMARDs (in monotherapy or in combination), and 37.4% with anti-TNFs (in monotherapy or in association with DMARDs). At 24 months, 35.1% were receiving anti-TNF therapy. The rate of DAS28 remission rates at 12 months and 24 months were 28.3% (95% confidence interval [CI] 19.1-37.5) and 41.6% (95% confidence interval [CI] 30.6-52.6), respectively.
Conclusions: The remission rate was lower at 12 months compared with previous large randomised clinical trials for early, aggressive RA, but significantly improved at 24 months. These results suggest that patients in real-world clinical settings in Italy may experience a delay in receiving the best possible care.
