OBJECTIVES The aim of this study was to assess the involvement of the endoplasmic reticulum aminopeptidase 1 (ERAP1) gene in AS susceptibility and functional severity in a Spanish population. METHODS Eight single nucleotide polymorphisms (SNPs) spanning the ERAP1 gene were genotyped by allele-specific fluorescent PCR in 300 AS Spanish patients and 300(More)
OBJECTIVE To evaluate the smallest detectable difference (SDD) of symptomatic outcome or process variables in ankylosing spondylitis (AS) patients from various countries. METHODS Thirty consecutive AS patients with axial involvement were recruited from 1 center in each of 4 countries (Spain, Morocco, France, The Netherlands), for a total of 120 patients.(More)

OBJECTIVES To determine the type and proportion of patients with ankylosing spondylitis who rheumatologists consider to be candidates for treatment with tumour necrosis factor (TNF)-blocking agents, and to what extent this is in agreement with the ASsessment in Ankylosing Spondylitis (ASAS) international working group recommendations on initiation of(More)
OBJECTIVES When evaluating patients for spondyloarthropathy, clinicians use the 'possible spondyloarthropathy' category to indicate that they are unsure about the diagnosis. We sought to determine whether Amor's criteria or the European Spondyloarthropathy Study Group (ESSG) criteria could lift thi uncertainty. PATIENTS AND METHODS During a Spanish study(More)
OBJECTIVE Recommendations and/or guidelines represent a popular way of integrating evidence-based medicine into clinical practice. The 3E Initiatives is a multi-national effort to develop recommendations for the management of rheumatic diseases, which involves a large number of experts combined with practising rheumatologists addressing specific questions(More)
