Diffuse large B cell lymphoma (DLBCL) is the largest subtype of non-Hodgkin's lymphomas (NHLs) and is characterized by relatively frequent extranodal presentation. In these cases, the most common extranodal localizations are stomach, CNS, bone, testis and liver. Simultaneous detection of multiple extranodal involvement at presentation is quite uncommon,(More)
INTRODUCTION Hyperthyroid Graves' disease (GD) is a B-cell-mediated condition caused by TSH receptor antibodies (TRAb), which decline when GD remits. Anti-CD20 monoclonal antibody rituximab (RTX) induces transient B-cell depletion that may potentially modify the active inflammatory phase of thyroid-associated ophthalmopathy (TAO). METHODS Nine patients(More)
OBJECTIVE Increased body iron stores and hepcidin have been hypothesized to promote atherosclerosis by inducing macrophage iron accumulation and release of cytokines, but direct demonstration in human cells is lacking. The aim of this study was to evaluate the effect of iron on cytokine release in monocytes ex vivo and the correlation with vascular damage(More)
The CD69 glycoprotein is an early activation antigen of T and B lymphocytes but it expression is induced in vitro on cells of most hematopoietic lineages, including neutrophils after stimulation with PMA or fMLP. In this study, we investigated whether CD69 expression on human neutrophils could be modulated by inflammatory or anti-inflammatory cytokines(More)
OBJECTIVE To investigate the role of antibodies reacting with beta 2 glycoprotein I (beta 2GPI) in the antiendothelial cell binding activity present in sera from patients with the anti-phospholipid syndrome. METHODS Sera positive for anti-phospholipid, anti-endothelial and anti-beta 2 GPI antibodies were studied for their binding activity on endothelial(More)
OBJECTIVE To investigate interactions of immune cells with vascular endothelium in patients with systemic sclerosis (SSc) and in patients with idiopathic or autoimmune Raynaud's phenomenon (RP). METHODS Lymphocytes obtained from 11 patients with SSc, 9 with RP and 14 control subjects were pre-stimulated in vitro with alloantigens and cultured together(More)
Monocytes differentiating in vitro into macrophages increase their capacity to ingest particles via FcgammaR and CR3. Because human recombinant IL-10 is a potent up-regulator of phagocytosis in human monocytes, we investigated whether spontaneously produced IL-10 could be a signal for the modulation of phagocytosis by cultured monocytes. We show here that(More)
The study compares the ability of the PSI (pneumonia severity index), CURB-65 (confusion, urea >7 mol·L(-1), respiratory rate ≥ 30 breaths·min(-1), blood pressure <90 mmHg systolic or ≤ 60 mmHg diastolic, and age ≥ 65 yrs), CURB and CRB-65 scales and the Severe Community-Acquired Pneumonia (SCAP) score to predict 30-day mortality in healthcare-associated(More)
