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.

Anti-citrullinated peptide antibodies and the progression of radiographic joint erosions in patients with early rheumatoid arthritis treated with FIN-RACo combination and single disease-modifying antirheumatic drug strategies.

Objectives: To evaluate the impact of antibodies to cyclic citrullinated peptide (ACPAs) on radiographic progression in patients with early rheumatoid arthritis (RA) initially treated either with a combination of 3 disease-modifying antirheumatic drugs (DMARDs) or with a single DMARD.

Methods: This study included 129 patients with early active RA initially randomised to treatment either with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone (FIN-RACo) (n=69) or with a single DMARD (initially sulfalasalazine) with or without prednisolone (SINGLE) (n=60). After 2 years, the use of DMARDs and prednisolone became unrestricted.

The predictive value of rheumatoid factor isotypes, anti-cyclic citrullinated peptide antibodies, and antineutrophil cytoplasmic antibodies for mortality in patients with rheumatoid arthritis.

Objective: To evaluate the significance of rheumatoid factor (RF) and its isotypes (IgA RF, IgG RF, and IgM RF), anti-cyclic citrullinated peptide antibodies (anti-CCP), and antineutrophil cytoplasmic antibodies (ANCA) in predicting mortality in patients with rheumatoid arthritis (RA).

Methods: The study population comprised 604 patients with RA participating in a cross-sectional study in 1987. Presence of RF (n = 604), RF isotypes (n = 206), anti-CCP (n = 184), and ANCA (n = 200) were determined in these patients from available baseline sera.

Antineutrophil cytoplasmic antibodies in patients with early rheumatoid arthritis: an early marker of progressive erosive disease.

Objective: To evaluate the clinical associations of antineutrophil cytoplasmic antibodies (ANCA) in patients with early rheumatoid arthritis (RA), as well as the possible predictive role of ANCA. We also assessed the overlap of ANCA with other specific serologic markers of RA.

Methods: Eighty-two RA patients with symptoms for < or = 12 months were studied for the presence of ANCA by immunofluorescence and specific enzyme immunoassays.
