OBJECTIVES Non-infectious aortitis is often refractory to standard immunosuppressive therapy. Since IL-6 has been implicated in the pathogenesis of aortitis, we assessed the efficacy of the anti-IL6 receptor monoconal antibody tocilizumab (TCZ) in a series of patients with refractory non-infectious aortitis. METHODS Review of 16 patients (14 women/2 men)(More)
UNLABELLED A formula for calculating disease activity score with 28 joint counts (DAS28) with C-reactive protein (CRP) instead of the erythrocyte sedimentation rate (ESR) has been proposed. OBJECTIVE Here we analyze the factors that contribute to the differences in the DAS28 when calculated using either the ESR (DAS28-ESR) or the CRP values (DAS28-CRP).(More)
OBJECTIVE To assess the efficacy of tocilizumab (TCZ) in giant cell arteritis (GCA) patients with refractory disease and/or with unacceptable side effects due to corticosteroids. METHODS A retrospective multicenter open-label study on 22 GCA patients treated with TCZ at standard dose of 8mg/kg/month. The main outcomes were achievement of disease remission(More)
The VLA-4 (CD49d/CD29) integrin is a cell surface receptor involved in the interaction of lymphoid cells with both extracellular matrix (ECM) and endothelial cells. We have investigated the expression and function of VLA-4 fibronectin (FN) receptors on T cells localized in the inflammed synovium of patients with rheumatoid arthritis (RA). A high proportion(More)
OBJECTIVE To study the expression of L-selectin, CD43, and CD44 on peripheral blood (PB) and synovial fluid (SF) neutrophils from patients with inflammatory joint diseases, and to investigate the presence of soluble L-selectin in both SF and plasma from patients with acute and chronic arthritis. METHODS PB and SF neutrophils were isolated from 13 patients(More)
BACKGROUND Interleukin-15 (IL-15) is thought to be involved in the physiopathological mechanisms of RA and it can be detected in the serum and the synovial fluid of inflamed joints in patients with RA but not in patients with osteoarthritis or other inflammatory joint diseases. Therefore, the objective of this work is to analyse whether serum IL-15 (sIL-15)(More)
Adhesion of T cells to extracellular matrix (ECM) proteins through VLA integrin receptors is crucial for lymphocyte trafficking, tissue localization and inflammatory function. We have investigated the expression of different VLA integrins (VLA-1-5) on peripheral blood (PB) and synovial fluid (SF) T lymphocytes from patients with rheumatoid arthritis (RA).(More)
OBJECTIVES To assess the efficacy of tocilizumab (TCZ) in patients with Takayasu arteritis (TA). METHODS Multicentre open-label retrospective study. RESULTS Eight patients (all women) with a mean age of 34±16 years, median 36 years (range: 7-57) were assessed. The main clinical features at TCZ therapy onset were: constitutional symptoms (n=4), fever(More)
The regulation of the cell surface expression of ICAM-3 (CD50) was investigated in human neutrophils. Immunofluorescence flow cytometry analysis revealed a remarkable and very rapid down-regulation of the ICAM-3 cell surface expression upon neutrophil activation with stimulating agents such as phorbol myristate acetate (PMA) or calcium ionophore.
