OBJECTIVE Different sets of diagnostic criteria have been proposed for Sjögren's syndrome (SS), but none have been validated with a large series of patients or in a multicenter study. We conducted the present study involving 26 centers from 12 countries (11 in Europe, plus Israel), with the goals of reaching a consensus on the diagnostic procedures for SS(More)
BACKGROUND AND OBJECTIVES Rituximab reacts specifically with the CD20 antigen and induces B-cell depletion. This could interfere with the production of autoantibodies in some immune diseases. The objective of this study was to assess the effects of rituximab in autoimmune hemolytic anemia and thrombocytopenia. DESIGN AND METHODS Seven patients (one with(More)
OBJECTIVE The aims of this study were to describe the clinical presentation of primary SS (pSS) in a large cohort of patients by assessing the prevalence of the patient subgroups at high risk for severe extraglandular manifestations and to explore the influence of the patients' serological profile on disease severity and on immunosuppressive drug(More)
BACKGROUND AND OBJECTIVES Rituximab is a chimeric anti-CD20 monoclonal antibody active against normal and malignant B cells. Treatment with rituximab is associated with the development of a severe (even if transient) B-cell depletion from peripheral blood and lymphatic tissues. These effects could be useful in autoimmune diseases in order to interfere with(More)
OBJECTIVE To evaluate the efficacy and safety in the long term of a retreatment regimen with Rituximab (RTX) alone administered at clinical relapse in cryoglobulinemic vasculitis (CV). METHODS Thirty patients with severe HCV-related CV, previously enrolled in the multicentre Italian trial on RTX in the treatment of CV, were retrospectively evaluated after(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)
To define the clinical and immunologic pattern of expression of Sjögren syndrome (SS) associated with chronic hepatitis C virus (HCV) infection, we conducted a multicenter study aiming to collect a large number of patients with SS and HCV infection. Inclusion criteria were the fulfillment of at least 4 of the classification criteria for SS proposed by the(More)
OBJECTIVE To determine factors affecting the severity of cognitive impairment in systemic lupus erythematosus (SLE) and to analyze its anatomic location. METHODS Fifteen cognitive functions grouped into 8 domains were evaluated in 52 patients with SLE and 20 with rheumatoid arthritis. Patients were classified according to severity of impairment as normal,(More)
OBJECTIVE Rituximab, an anti-CD20 monoclonal antibody, has been used in lupus nephritis and membranous idiopathic nephropathy and has proved effective in non-renal manifestations of type II mixed cryoglobulinaemia (MC) syndrome. We investigated the possible efficacy and safety of rituximab in the treatment of cryoglobulinaemic nephritis. METHODS Five(More)
OBJECTIVES To investigate the role of B-Lymphocyte stimulator (BLyS) in mixed cryoglobulinaemia syndrome (MCsn), a systemic vasculitis associated with a high risk to develop lymphoma, since BLyS up-regulation may favour both autoimmunity and lymphoproliferation. METHODS BLyS serum levels were analysed by enzyme-linked immunosorbent assay (positive when(More)
