We conducted the current study to characterize the clinical presentation of primary Sjögren syndrome (SS) in a large cohort of Spanish patients and to determine whether epidemiologic, clinical, and analytical features modulate disease expression. Patients were from the GEMESS Study group, which was formed in 2005 and included 12 Spanish reference centers.(More)
OBJECTIVE To determine survival and mortality in a cohort of Spanish patients with scleroderma (systemic sclerosis, SSc) and to analyse whether survival is influenced by demographic, clinical or immunological variables or the extent of skin involvement. METHODS The study included 79 patients diagnosed with SSc and taking part in a study to determine the(More)
OBJECTIVES To analyse the influence of geolocation and ethnicity on the clinical presentation of primary Sjögren's syndrome (SjS) at diagnosis. METHODS The Big Data Sjögren Project Consortium is an international, multicentre registry designed in 2014. By January 2016, 20 centres from five continents were participating. Multivariable logistic regression(More)
UNLABELLED Salivary gland dysfunction has been described in patients undergoing radioiodine therapy but associated lacrimal gland dysfunction (sicca syndrome) has never been reported. We conducted a prospective cohort study with follow-up for up to 3 y in a tertiary care university center to determine the prevalence of sicca syndrome in patients after(More)
OBJECTIVE To identify survival prognostic factors and markers of morbidity among patients with systemic sclerosis (SSc). PATIENTS AND METHODS The study included 72 patients diagnosed with SSc. According to the extent of skin involvement, three groups of patients were established: group 1, without sclerosis and with sclerosis of fingers and neck; group 2,(More)
OBJECTIVE To elucidate whether oxidative injury occurs in systemic sclerosis (SSc) and whether it affects the erythrocyte membrane (EM) properties. METHODS EM fluidity and lipid composition (cholesterol:phospholipid molar ratio [C:PL], fatty acid composition) were studied in 52 patients with SSc and in 53 subjects without SSc (32 with primary Raynaud's(More)
OBJECTIVE Signal-transducer and activator of transcription protein 3 (STAT3) gene encodes a transducer and transcription factor that plays an important role in many cellular processes such as cell growth, apoptosis and immune response. Several STAT3 genetic variants have been associated to different autoimmune diseases. Our aim was to reveal the possible(More)
