BACKGROUND AND PURPOSE DTI has shown increased MD of water molecules in the brain of patients with cirrhosis, consistent with low-grade edema. This study further characterizes this edema by using biexponential analysis of DTI data, a technique that may differentiate cytotoxic and vasogenic edema. MATERIALS AND METHODS A total of 41 patients with cirrhosis(More)
OBJECTIVES To examine the prevalence of seizures, epilepsy and seropositivity to cysticercosis in rural villagers (cysticercosis-endemic setting), rural-to-urban migrants into a non-endemic urban shanty town and urban inhabitants of the same non-endemic shanty town. METHODS Three Peruvian populations (n = 985) originally recruited into a study about(More)
The frequency of hepatitis C virus (HCV) infection in Spain was assessed by means of a recombinant-based immunoassay for serum anti-HCV antibodies. 836 serum samples were tested from 676 patients selected according to their risk of blood-borne viral infections and presence of liver disease. Among patients at high risk of infection (with or without liver(More)
We analysed the humoral immune response to glatiramer acetate (GA, Copaxone) in 20 multiple sclerosis patients treated with GA, 20 patients not treated with GA and 20 normal control subjects. Using an ELISA for detection of total GA-reactive immunoglobulins (all isotypes), all treated patients but also 3/20 untreated and 8/20 healthy subjects scored(More)
BACKGROUND AND AIMS The risk of recurrent hepatitis B virus (HBV) infection and prognosis of liver transplantation in patients with HBV has dramatically changed with the use of prophylaxis including hepatitis B immune globulin (HBIg) and antiviral agents. METHODS This study analyzes the prognostic value of HBV DNA level before orthotopic liver(More)
To determine whether cytomegalovirus (CMV) disease is an independent risk factor for graft loss and death after orthotopic liver transplantation, we performed a 3-year follow-up study of 143 consecutive liver transplant recipients and six patients who underwent retransplantation. Thirty-seven patients (25%) had had CMV disease and were alive after(More)
BACKGROUND & AIMS To study the origin of fat excess in the livers of morbidly obese (MO) individuals, we analysed lipids and lipases in both plasma and liver and genes involved in lipid transport, or related with, in that organ. METHODS Thirty-two MO patients were grouped according to the absence (healthy: DM - DL -) or presence of comorbidities(More)
