We evaluated cerebrospinal fluid (CSF) and serum concentrations of interleukin-1-alpha (IL-1 alpha), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-alpha) in 30 patients with AIDS dementia complex (ADC), and in 20 HIV-seronegative subjects with other neurological diseases (OND). CSF TNF alpha, IL-1-alpha and IL-6 were more frequently detectable(More)
Mechanisms involved in the pathogenesis of the AIDS-dementia complex are still unclear. The dichotomy between a small number of HIV-infected cells in the brain and their marked dysfunction could be related to a cellular amplification and/or activation of cerebral viral load by several cytokines. This link between cytokines and viral load could play a role(More)
OBJECTIVE To evaluate the efficacy and safety in the long term of a retreatment regimen with Rituximab (RTX) alone administered at clinical relapse in cryoglobulinemic vasculitis (CV). METHODS Thirty patients with severe HCV-related CV, previously enrolled in the multicentre Italian trial on RTX in the treatment of CV, were retrospectively evaluated after(More)
The continuous identification of HIV-1 non-B subtypes and recombinant forms in Italy indicates the need of constant molecular epidemiology survey of genetic forms circulating and transmitted in the resident population. The distribution of HIV-1 subtypes has been evaluated in 25 seropositive individuals residing in Italy, most of whom were infected through a(More)
BACKGROUND Few studies are available on possible hepatitis C virus (HCV)-specific T-cell immune response in health care workers (HCWs) involved in the care of patients with HCV infection. We aimed to investigate whether a HCV-specific interferon (IFN)-gamma T-cell response, known to be involved in infection resolution, was present in those HCWs involved in(More)
To determine the association among the clinical, biochemical, and histological features of cholestasis, we analyzed all the relevant data of the patients recorded in our non-alcoholic fatty liver disease (NAFLD) database. We selected 20 NAFLD patients with abnormal transaminase levels, with both alkaline phosphatase ≥500 U/L and γ-glutamyl transpeptidase(More)
Levels of tumor necrosis factor (TNF)-alpha, granulocyte macrophage-colony stimulating factor (GM-CSF), interleukin (IL)-10 and transforming growth factor (TGF)-beta in cerebrospinal fluid (CSF) and serum of 29 patients with multiple sclerosis (MS) of the relapsing-remitting type and of 20 controls with other non inflammatory neurological diseases were(More)
Cerebrospinal fluid (CSF) and serum levels of transforming growth factor (TGF)-beta and soluble intercellular adhesion molecule-1 (sICAM-1) were evaluated in ten patients with definite multiple sclerosis (MS) of the relapsing-remitting type. CSF TGF-beta levels of MS patients in remission were significantly (p < 0.01) higher than of MS patients in active(More)
AIM To asses the expression of myeloid dendritic cells (CD11c+) subset during acute HCV hepatitis and its possible involvement in natural history of the infection. METHODS We enrolled 11 patients with acute hepatitis C (AHC) (Group A), 10 patients with acute hepatitis A (AHA) (as infective control-Group B) and 10 healthy donors (group C) in this study.(More)
BACKGROUND AND AIM Refractory ascites in liver-cirrhosis is associated with a poor prognosis. We performed a prospective study to investigate whether aggressive nutritional-support could improve outcomes in cirrhotic patients. METHODS Cirrhotic patients undergoing serial large-volume paracentesis for refractory-ascites were enrolled and randomized into(More)
