The effects of interferon-alpha (IFN-alpha) on clinical and serologic manifestations of mixed cryoglobulinemia (MC) were investigated by randomized, crossover-controlled trial in 26 patients. The trial alternated 6 months with and 6 months without IFN-alpha therapy (2 x 10(6) IU daily for a month, then every other day for 5 months). In 22 patients,(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)
OBJECTIVE To assess the 1-year efficacy and safety of a regimen of tocilizumab plus methotrexate or placebo, which was augmented by a treat-to-target strategy from week 24. METHODS ACT-RAY was a double-blind, 3-year trial. Adults with active rheumatoid arthritis despite methotrexate were randomised to add tocilizumab to ongoing methotrexate (add-on(More)
A therosclerosis is a multifactorial process that commences in childhood but manifests clinically later in life. Atherosclerosis is increasingly considered an immune system–mediated process of the vascular system. The presence of macrophages and activated lymphocytes within ath-erosclerotic plaques supports the concept of atherosclerosis as an immune(More)
Objective-To assess the recently proposed preliminary criteria for the classification of Sjogren's syndrome (SS) in a multicentre European study of a new series of clinically defined cases. Methods-The criteria included six items: I = ocular symptoms; II = oral symptoms; II = evidence of keratoconjunctivitis sicca; IV = focal sialoadenitis by minor salivary(More)
OBJECTIVE To assess the prevalence and clinical and serological associations of anti-ribosomal P protein antibodies (anti-P antibodies) in patients with connective tissue diseases (CTDs) and investigate the immunobiological nature of autoantibody clustering in which anti-P antibodies play a part. METHODS IgG anti-P antibodies in the sera of 267 patients(More)
Several lines of evidence point to a profound remodelling of the cytokine network in healthy elderly subjects, with decreased type-1 cytokine production (IL 2) and a shift to type 0 and 2. We have also observed an increase of proinflammatory cytokines (IL-1, IL-6, TNF-alpha) in vitro, and an increase of circulating stem cell factor in vivo. In this setting,(More)
OBJECTIVE To evaluate the contribution of the MHC class I chain-related A (MICA) gene polymorphism to the genetic risk of systemic lupus erythematosus (SLE). METHODS HLA-DRB1-DQA1-DQB1 genotyping, MICA exon 5 microsatellite genotyping and HLA-B8 genotyping were performed in 48 Italian SLE patients and in 158 healthy control subjects. RESULTS Of HLA(More)
OBJECTIVE To study those conditions with a proven or hypothesised immunologic pathogenesis and denominated under a working definition of undifferentiated connective tissue diseases (UCTD). METHODS A multicentre prospective study was organised involving 10 tertiary referral centers of internal medicine in Italy, with the aim of describing the natural(More)
T-cell cytokines play a crucial role in the pathogenesis and progression of rheumatoid arthritis (RA). Their detection in the joint, however, is impaired by the complex network present in the synovium. Although many synovial T cells show signs of previous activation, only a few express interleukin (IL)-2 receptor, marker of recent activation. The aim of(More)
