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)
OBJECTIVE To conduct a long-term, prospective, randomized controlled trial evaluating rituximab (RTX) therapy for severe mixed cryoglobulinemia or cryoglobulinemic vasculitis (CV). METHODS Fifty-nine patients with CV and related skin ulcers, active glomerulonephritis, or refractory peripheral neuropathy were enrolled. In CV patients who also had hepatitis(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)
BACKGROUND Highly active antiretroviral therapy (HAART) is strongly effective in reducing morbidity and mortality in HIV-1-positive individuals. Its main drawback is the potential toxicity. Data on the frequency and determinants of severe hepatotoxicity in a clinical setting are still sparse. METHODS This is a prospective study of HIV-1-positive(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)
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 gamma-glutamyl(More)
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)
The authors evaluate the involvement of various cytokines (interleukin-1, interleukin-2, interleukin-4, interleukin-6, tumor necrosis factor alpha and gamma-interferon) in the pathogenesis of multiple sclerosis. The cytokines might participate in nervous tissue damage by promoting demyelination and oligodendrocyte injury or by enhancing local immune(More)
We detected the cytokines interleukin-6 (IL-6) and granulocyte macrophage-CSF (GM-CSF) by ELISA in the CSF and serum of 30 HIV-infected patients classified as AIDS dementia complex (ADC), and 20 subjects with other neurological diseases (OND). We have found a high incidence of detectable IL-6 and GM-CSF in the CSF of ADC patients compared with OND patients.(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)
