Spanish Registry of Recent-onset Psoriatic Arthritis (REAPSER study): Aims and methodology.

Aims: To describe the methodology of REAPSER (Spanish Registry of Recent-onset Psoriatic Arthritis), its strengths and limitations. The aim of this study is to identify prognostic factors for the clinical and radiographic course in a cohort of patients with psoriatic arthritis (PsA) diagnosed within 2years of symptom evolution.

Methods: Multicenter, observational and prospective study (with 2-year follow-up including annual visits).

Two-year efficacy of tocilizumab in patients with active rheumatoid arthritis in clinical practice.

Objectives: To evaluate the efficacy of tocilizumab (TCZ) in patients with rheumatoid arthritis (RA) in clinical practice, retention rates of the drug and predictors of response.

Methods: We performed a descriptive, prospective, longitudinal, open-label study in patients receiving TCZ (8mg/kg/4 weeks) in a clinical practice setting. The clinical responses were evaluated using the European League Against Rheumatism (EULAR) response criteria, and the low activity and remission rates according to the Disease Activity Score 28-erythrocyte sedimentation rate (DAS28-ESR) and the Clinical Disease Activity Index (CDAI).
