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)
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)
We studied interferon-gamma (IFN-gamma), alpha-tumor necrosis factor (alpha-TNF) and granulocyte macrophage colony-stimulating factor (GM-CSF) in the cerebrospinal fluid and serum of 18 patients with multiple sclerosis (MS) and 10 subjects with other neurological diseases (OND). We also studied the cerebrospinal-fluid CD 69 expression, and T cells with T(More)
Hepatitis C virus (HCV) is one of the major risk factors for chronic hepatitis, which may progress to cirrhosis and hepatocellular carcinoma, as well as for type II mixed cryoglobulinemia (MC), which may further evolve into an overt B-cell non-Hodgkin's lymphoma (NHL). It has been previously shown that B-cell receptor (BCR) repertoire, expressed by clonal(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)
OBJECTIVE 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. METHODS The distribution of HIV-1 subtypes has been evaluated in 25 seropositive individuals residing in Italy, most of whom(More)
Cerebrospinal fluid (CSF) and serum concentration of beta-2-microglobulin (beta-2-m) were evaluated in 30 patients in various stages of HIV-1 infection. CSF beta-2-m and CSF/serum ratio were significantly higher in patients with neurological complications respect to asymptomatic subjects. These findings indicate that CSF beta-2-m and CSF/serum ratio may be(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)
OBJECTIVES The mechanisms involved in the pathogenesis of relapsing-remitting multiple sclerosis are still unclear. The aim of the present study was to evaluate both cerebrospinal fluid (CSF) CD4+ CD7+ T cells and peripheral blood (PB) interleukin-10 (IL-10) as well as tumor necrosis-alpha (TNF-alpha) levels in patients with definite multiple sclerosis of(More)
The aim of the present study was to assess the significance of IgE and interleukin-6 (IL-6) in paired CSF and serum of patients with viral and bacterial infections of the central nervous system. The results suggest that the detection of IL-6 and IgE in CSF is an useful marker for monitoring course and prognosis of these patients.
