Dermatitis herpetiformis (DH) is an autoimmune blistering skin disease associated with gluten-sensitive enteropathy (CD). In order to investigate the pathogenesis of skin lesions at molecular level, we analysed the gene expression profiles in skin biopsies from 6 CD patients with DH and 6 healthy controls using Affymetrix HG-U133A 2.0 arrays. 486 genes were(More)
Vasculopathy, immunological abnormalities, and excessive tissue fibrosis are key elements in the pathogenesis of progressive systemic sclerosis (SSc). Extracorporeal shock waves (ESW) have anti-inflammatory and regenerative effects on different tissues. We hypothesized that ESW can reduce endothelial cell damage and skin fibrosis in patients with SSc. We(More)
BACKGROUND Human cytomegalovirus (hCMV) is involved in the pathogenesis of atherosclerosis. We have previously shown in patients with atherosclerosis that antibodies directed against the hCMV-derived proteins US28 and UL122 are able to induce endothelial cell damage and apoptosis of non-stressed endothelial cells through cross-rection with normally(More)
INTRODUCTION Circulating endothelial cells are increased in patients affected by systemic sclerosis (SSc) and their number strongly correlates with vascular damage. The effects of iloprost in systemic sclerosis are only partially known. We aimed at studying the gene expression profile of circulating endothelial cells and the effects of iloprost infusion and(More)
The objectives of the study are to evaluate DNase I serum levels and their correlation with soluble Fas (sFas) and soluble Fas ligand (sFasL) and with cell surface Fas expression in patients with systemic lupus erythematosus (SLE), thus contributing to the dysregulated apoptosis typical of the disease. The methods include the following: Serum DNase I levels(More)
BACKGROUND Psoriatic arthritis (PsA) is a chronic inflammatory disease of unknown origin, characterized by erosions and new bone formation. Diagnosis of PsA is mainly clinical and there are no biomarkers available. Moreover in PsA autoantibodies have not been described so far. Indeed an autoimmune origin has been suggested but never proven. Aim of the study(More)
BACKGROUND Regular intravenous immunoglobulin treatment is used to replace antibody deficiency in primary immunodeficiency diseases; however the therapeutic effect seems to be related not only to antibody replacement but also to an active role in the modulation of the immune response. Common variable immunodeficiency is the most frequent primary(More)
We describe the case of a 59 year old man with systemic sclerosis and superficial siderosis of the central nervous system characterized by progressive worsening of walking with signs of pyramidal liberation associated with cerebellar ataxia and bilateral hypoacusia. Ferritin and oligoclonal bands were found on lumbar puncture and Magnetic Resonance Imaging(More)
Human cytomegalovirus (hCMV) infection and its reactivation correlate both with the increased risk and with the worsening of graft-versus-host disease (GVHD). Because scleroderma-like skin lesions can occur in chronic GVHD (cGVHD) in allogeneic stem-cell transplant (HCT) patients and hCMV is relevant in the pathogenesis of systemic sclerosis (SSc), we(More)
Ankylosing spondylitis (AS) is a chronic inflammatory arthritis of unknown origin. Its autoimmune origin has been suggested but never proven. Several reports have implicated Klebsiella pneumoniae as a triggering or perpetuating factor in AS; however, its role in the disease pathogenesis remains debated. Moreover, despite extensive investigations, a(More)
