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)
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)
Iloprost is a stable prostacyclin analog commonly employed in the treatment of peripheral vascular disease and also indicated in the treatment of patients affected by systemic sclerosis (SSc) in the presence of severe Raynaud's phenomenon (RP). Several mechanisms of action of the drug other than vasodilation and antiplatelet effect have been demonstrated(More)
citing role as increased levels of dopamine have been shown to cause choroidal vasodilation. The time course of effusion development in this case is similar to that with topiramate. This suggests that if bupropion use were causative, one of its major active metabolites, hydroxybupropion or theobupropion (both with half-lives similar to that of topiramate),(More)
Rituximab (RTX) has been shown in previous work to improve thyroid-associated ophthalmopathy (TAO), but very little data is available on the effects of RTX in the target tissues. We studied the effects of RTX on peripheral lymphocytes and on the intra-orbital infiltrates in one patient with severe TAO who was treated with two cycles of therapy.(More)
In active Graves' orbitopathy (GO), proinflammatory cytokines predominate. Circulating thyroid stimulating hormone (TSH)-receptor antibodies (TRAb) have been correlated with GO clinical activity and severity. In preliminary studies rituximab (RTX), an anti-CD 20 monoclonal antibody, has induced clinical improvement of active GO without a change in serum(More)
In vitro models of human erythropoiesis are useful in studying the mechanisms of erythroid differentiation from BFU-E to mature erythrocytes both in normal and pathological conditions. Most of the available in vitro liquid cultures are from cell lines or are limited by the production of few erythroid cells mixed with myeloid cells. Here we describe an(More)
BACKGROUND Pru p 3 is the major peach allergen recognized by more than 90% of peach-allergic individuals of the Mediterranean area. Identification of the dominant Pru p 3 T-cell epitopes can improve our understanding of the immune responses against this protein and could be helpful in the development of hypoallergenic immunotherapy. For this purpose, we(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)
