The antiphospholipid syndrome (APS) is defined by the presence of thrombosis and/or pregnancy morbidity in combination with the persistent presence of circulating antiphospholipid antibodies: lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein I antibodies in medium to high titers. The management of thrombosis in patients with APS is(More)
OBJECTIVE The aim of this study was to analyse the relationship between glucocorticoids and damage accrual in SLE. METHODS We report an observational cohort study including 230 patients with SLE enrolled at diagnosis with 5 years of follow-up. Damage was calculated using the SLICC damage index. Glucocorticoid-related damage was defined as avascular(More)
INTRODUCTION Infections commonly complicate the course of systemic lupus erythematosus (SLE). Our aim is to investigate the clinical predictors of major infections in patients with SLE. METHODS A nested case-control study design was used within the prospective Lupus-Cruces cohort. The endpoints of the study were major infections. Cases were defined as(More)
OBJECTIVE To compare the efficacy and safety of high vs. low-moderate oral doses of prednisone to treat patients with highly active lupus at diagnosis. PATIENTS AND METHODS Patients from the Lupus-Cruces cohort with an SLEDAI score ≥6 at diagnosis and treated with regimes containing low-medium prednisone doses (≤30 mg/day) were identified (group M). They(More)
PURPOSE To assess the safety and efficacy of intravitreal dexamethasone implants in the treatment of macular edema secondary to infectious uveitis. METHODS We retrospectively reviewed clinical records from three uveitis referral units in Spain. The main outcome measures were rate of reactivation of infection, improvements in visual acuity and resolution(More)
OBJECTIVE A state of minimal disease activity (MDA) was defined and validated as target for treatment in psoriatic arthritis (PsA). We aimed to identify disease characteristics, outcome, and predictors of MDA in patients treated with tumor necrosis factor α (TNFα) blockers. METHODS Patients fulfilling the Classification of Psoriatic Arthritis criteria(More)
BACKGROUND Large-scale genetic studies have reported several loci associated with specific disorders involving uveitis. Our aim was to identify genetic risk factors that might predispose to uveitis per se, independent of the clinical diagnosis, by performing a dense genotyping of immune-related loci. METHODS 613 cases and 3693 unaffected controls from(More)
This study was undertaken to investigate the possible genetic association of functional CTLA4 polymorphisms with susceptibility to non-anterior uveitis. Four hundred and seventeen patients with endogenous non-anterior uveitis and 1517 healthy controls of Spanish Caucasian origin were genotyped for the CTLA4 polymorphisms rs733618, rs5742909 and rs231775,(More)
OBJECTIVE To analyse the differential influence of risk factors of peripheral artery disease (PAD) according to age in patients with SLE. METHODS 216 patients from the Lupus-Cruces cohort were divided in three age groups: ≤34 years, 35-49 years and ≥50 years. A low ankle-brachial index defined PAD. Significant variables were identified by univariant and(More)
BACKGROUND/AIMS A pathogenic role of Th17 cells in uveitis has become clear in recent years. Therefore, in the present study, we aimed to evaluate the possible influence of the IL17A locus on susceptibility to non-anterior uveitis and its main clinical subgroups. METHODS Five IL17A polymorphisms (rs4711998, rs8193036, rs3819024, rs2275913 and rs7747909),(More)
