OBJECTIVES To compare over 2 years the safety, efficacy and radiographic outcomes of subcutaneous abatacept versus adalimumab, in combination with methotrexate (MTX), in patients with rheumatoid arthritis (RA). METHODS AMPLE is a phase IIIb, 2-year, randomised, investigator-blinded study with a 1-year primary endpoint. Biologic-naive patients with active(More)
BACKGROUND Over the last decade, significant progresses have been achieved in the development and validation of new tools for the evaluation of disease activity in axial spondyloarthritis (SpA). Despite they play a key role in the assessment of these patients, the calculation scores are relatively complex and difficult to be quickly assessed in the busy(More)
OBJECTIVE To describe differential characteristics of axial involvement in ankylosing spondylitis (AS) as compared with that seen in psoriatic arthritis (PsA) and inflammatory bowel disease (IBD) in a cohort of Ibero-American patients. METHODS This study included 2044 consecutive patients with spondyloarthritis (SpA; ESSG criteria). Demographic, clinical,(More)
BACKGROUND The Health Assessment Questionnaire (HAQ) is one of the most frequently used instruments to assess functional capacity in activities of daily living. OBJECTIVE The objective of our study was to determine the reproducibility and validity of an Argentinean version of the HAQ disability index (HAQ-DI) in patients with rheumatoid arthritis (RA).

This study aimed to develop a simplified version of the Ankylosing Spondylitis Disease Activity Score (ASDAS). The study included consecutive patients with ankylosing spondylitis according to modified New York and/or Assessment in Ankylosing Spondylitis 2009 criteria. Sociodemographic data and characteristics of the disease (Bath Ankylosing Spondylitis(More)
Pulmonary involvement is one of the extra-articular manifestations of rheumatoid arthritis (RA) and includes pleurisy, parenchymal nodules, interstitial involvement, and airway disease. Rheumatoid pulmonary vasculitis is rare. Pulmonary disease also may be observed as a toxic event consequent to treatment for RA. Although RA is more common in women,(More)
OBJECTIVE There is a need for comparative studies to provide evidence-based treatment guidance for biologic agents in rheumatoid arthritis (RA). Therefore, this study was undertaken as the first head-to-head comparison of subcutaneous (SC) abatacept and SC adalimumab, both administered along with background methotrexate (MTX), for the treatment of RA.

The aim of the study was to determine the possible effect of melatonin treatment on disturbed sleep, fatigue and pain symptoms observed in fibromyalgia (FM) patients. Twenty-one consecutive patients with FM were included in an open 4-week-duration pilot study. Before and after treatment with melatonin 3 mg at bedtime, patients were evaluated using tender(More)
OBJECTIVE To identify susceptibility loci for rheumatoid arthritis (RA) in Latin American individuals with admixed European and Amerindian genetic ancestry. METHODS Genotyping was performed in 1,475 patients with RA and 1,213 control subjects, using a customized BeadArray containing 196,524 markers covering loci previously associated with various(More)
OBJECTIVE To assess the efficacy of etanercept in the treatment of early active nonsteroidal antiinflammatory drug (NSAID)-refractory nonradiographic axial spondyloarthritis (SpA). METHODS The study population consisted of patients who met the Assessment of SpondyloArthritis international Society (ASAS) classification criteria for axial SpA but not the(More)
