Terlipressin and albumin in patients with cirrhosis and type I hepatorenal syndrome.

Purpose: Hepatorenal syndrome (HRS) is a pre-renal-like dysfunction that generally onsets in cirrhotic patients presenting ascites. We investigated the improvement of renal function in subjects with hepatorenal syndrome after terlipressin administration and the survival times after this treatment. Fifty-two patients affected by cirrhosis, with diagnosis of hepatorenal syndrome were treated with intravenous terlipressin plus albumin (group A) or with albumin alone (group B).

Immune response in addicts with chronic hepatitis C treated with interferon and ribavirin.

Background: The role played by the immune system in the progression of chronic hepatitis C (CHC) is not completely clear. Opioids may facilitate the outbreak of infections through marked immunomodulating effects on the immune response against a virus. To asses if addicts can be treated successfully with interferon (IFN) during detoxification treatment, we evaluated some immune response mediators in addicts affected by CHC.

Psychiatric symptoms induced by antiviral therapy in chronic hepatitis C: comparison between interferon-alpha-2a and interferon-alpha-2b.

Background And Objective: Interferon-alpha treatment is associated with a large number of adverse effects. Depressive symptoms are not unexpected, and potentially dangerous psychiatric adverse effects can induce life-threatening conditions. We compared the incidence of depressive symptoms in patients with chronic hepatitis C during treatment with pegylated interferon-alpha-2a (IFNalpha-2a) and pegylated interferon-alpha-2b (IFNalpha-2b).

Oxidative stress, nitric oxide, endothelial dysfunction and tinnitus.

To assess whether pathogenic endothelial dysfunction is involved in acute idiopathic tinnitus we enrolled 44 patients and 25 healthy volunteers. In blood from the internal jugular vein and brachial vein we determined malonaldehyde, 4-hydroxynonenal, myeloperoxidase, glutathione peroxidase, nitric oxide, L-arginine and L-ornitine, thrombomodulin (TM) and von Willebrand factor (vWF) activity during tinnitus and asymptomatic period. Higher plasma concentrations of oxidative markers and L-arginine, and lower nitric oxide and L-ornitine levels were observed in jugular blood of patients with tinnitus, there being a significant difference between brachial and jugular veins.

Effects of antioxidant supplementation on postprandial oxidative stress and endothelial dysfunction: a single-blind, 15-day clinical trial in patients with untreated type 2 diabetes, subjects with impaired glucose tolerance, and healthy controls.

Background: Increased generation of reactive oxygen species (ROS) and oxidative stress may be of crucial importance in the pathogenesis of endothelial damage. Furthermore, there is understood to be a relationship between endothelial damage, glycemic control, disorders of lipid metabolism, and coagulative hemostatic disorders.

Objective: This study investigated within- and between-group changes in various circulating markers of oxidation-reduction balance and endothelial function after a balanced moderate-fat meal with and without antioxidant supplementation in patients with early-stage, untreated type 2 diabetes mellitus; subjects with impaired glucose tolerance (IGT); and healthy controls.

Can ultrasonographic findings of perihepatic lymphadenopathy promote investigations to detect possible presence of virus C infection in non-symptomatic subjects?

PURPOSE: Only early detection of non-symptomatic patients is able to arrest the diffusion of the non-symptomatic HCV infection and lead to prompt treatment. Our aim was to attempt to correlate the presence of perihepatic lymph nodes and hepatitis C infection and to assess whether ultrasonography can have a role to promote specific investigations for pre-clinical diagnosis of virus C infection. METHOD: We performed a controlled study on a cohort of 7974 subjects from a town of 27000 inhabitants on the eastern coast of Sicily.

Controlled clinical trial to assess the response of recent heroin abusers with chronic hepatitis C virus infection to treatment with interferon alpha-n2b.

Background: Chronic infection with hepatitis C virus (HCV) is the most common infectious disease among heroin abusers, but it is recommended that specific treatment with interferon be delayed until at least 6 to 12 months after the end of drug addiction.

Objective: We investigated the response of heroin abusers to interferon treatment shortly after the end of detoxification treatment with methadone.

Methods: We studied 2 homogeneous groups of white Italian patients with chronic HCV infection: former male heroin abusers and males without a history of drug addiction.
