OBJECTIVE: To develop valid instruments for the assessment of disease-related damage and disease activity in Sjögren's syndrome (SS).

METHODS: Data on 206 patients with primary SS were collected in 12 Italian centers. Each patient was scored by 1 investigator, on the basis of a global assessment of the degree of disease damage and disease activity. Patients judged to have active disease at the time of enrollment underwent a second evaluation after 3 months. Univariate and multivariate ...

OBJECTIVE: Mixed cryoglobulinemia syndrome (MCs) is a systemic vasculitis characterized by multiple organ involvement due to the vascular deposition of immune-complexes, mainly the cryoglobulins. B-lymphocyte expansion represents the underlying pathological alteration frequently triggered by hepatitis C virus (HCV) infection. The treatment of MCs syndrome is generally based on antiviral drugs and/or immunosuppressors, among which rituximab, an anti-CD20 monoclonal antibody, has been ...

BACKGROUND: Even when treated with current protocols, 25 to 30% of systemic lupus erythematosus (SLE) patients with diffuse proliferative glomerulonephritis (DPGN) evolve to end-stage renal disease (ESRD). The occurrence of renal flares is considered to be an important risk factor for the evolution to ESRD. The aim of this retrospective study was to evaluate the incidence and prognostic significance of renal flares in SLE patients with DPGN and to identify predictors for the occurrence ...

The objective of this work was to evaluate the clinical and serological profiles of patients with undifferentiated connective tissue diseases (UCTD) who had been followed for at least 1 year. The retrospective analysis (197495) was based on UCTD patients diagnosed on the basis of clinical manifestations suggestive of a connective tissue disease, and the presence of at least one non-organ-specific autoantibody. A total of 91 patients were evaluated. The condition of 79 remained stable ...

OBJECTIVE: To conduct a long-term, prospective, randomized controlled trial evaluating rituximab (RTX) therapy for severe mixed cryoglobulinemia or cryoglobulinemic vasculitis (CV).

METHODS: Fifty-nine patients with CV and related skin ulcers, active glomerulonephritis, or refractory peripheral neuropathy were enrolled. In CV patients who also had hepatitis C virus (HCV) infection, treatment of the HCV infection with antiviral agents had previously failed or was not indicated. Patients ...

BACKGROUND/AIM: The IgG4-related disease (IgG4-RD) is a fibroinflammatory condition that can affect almost any organ, often associated with eosinophilia and increased levels of IgE and IgG4. Overexpression in tissues of Th2-related cytokines but also of IFN-γ has been reported. Given the major role of Il-1 family cytokines in inducing and regulating inflammation, and the paucity of data so far available in IgG-RD, we performed a comprehensive analysis of IL-18, related IL-1 family ...

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 utilization.

METHODS: Cumulative demographic, clinical, serological, histological and therapeutic data of 1115 pSS patients were ...

Undifferentiated connective tissue disease (UCTD) is a group of systemic autoimmune conditions not fulfilling the classification criteria for a definite connective tissue disease (CTD). While an average of 20% of UCTD patients develop a defined CTD during follow-up, the remaining patients maintain an undefined disease. Since pregnancy is considered to be an important factor that may alter the course of autoimmune diseases, we examined 25 pregnancies in 20 UCTD patients being followed at ...

Chronic glucocorticoid (GC) therapy is associated with an increased risk of developing cataracts and glaucoma, and recommendations have been developed for monitoring these side effects in patients with rheumatic diseases. The aim of this study was to assess the prevalence of cataracts and glaucoma and the adherence to the existing recommendations for monitoring eye toxicity of chronic GC therapy among systemic lupus erythematosus (SLE) patients in routine clinical practice. Clinical ...

Lung function was assessed in 20 patients with primary Sjögren's syndrome (SS) and in a group of patients with SS associated with a variety of connective tissue diseases. Signs of small airway disease and of altered diffusion capacity, together with chest x-ray features of mild interstitial involvement, were the most common findings in primary SS. On the whole, lung involvement was more frequent and severe in patients with the secondary form of the syndrome. In both primary and secondary ...

Rituximab (RTX) represents a milestone in the treatment of mixed cryoglobulinemic vasculitis (MCV). Despite usually well-tolerated, RTX may induce different types of adverse drug reactions, including exacerbation of vasculitis. Recently, RTX biosimilar CT-P10 has been approved in Europe for the treatment of rheumatoid arthritis, but no data are available about effectiveness and safety of CT-P10 in the treatment of MCV. In this multicenter open-label study, we analyzed the safety of ...
