The purpose of this study was to evaluate the prevalence of intestinal parasites in 277 healthy subjects in the city of Mamuras (Albania, South Eastern Europe) and the correlation between parasitic infections and possible risk factors. Faecal samples collected with sodium-acetate-formalin fixative were concentrated by formalin ethylacetate sedimentation and(More)
This study presents the initial results derived from a collaborative project aimed at the surveillance of the toxoplasma infection in a population of 496 Albanian pregnant women. From October 2004 to March 2005, serum samples were tested to detect IgG, IgM and IgG avidity for toxoplasmosis. Of the 496 pregnant women examined, 241 (48.6% [range 44-53]; IC(More)
Sera from 28 HBsAg chronic carriers were tested for the presence of HBeAg, anti-HBe and Dane particle-associated DNA-polymerase activity, in order to evaluate the relationship between the presence of these markers and the spread of HBV infection in their family contacts. A highly significant prevalence of HBV infection was observed in the relatives of HBsAg(More)
The prevalence of serum markers of primary delta infection was determined in 532 patients with acute benign hepatitis B seen in Italy, and in 111 patients with fulminant hepatitis B seen in Italy, France and England. Patients with fulminant hepatitis had significantly higher prevalence of delta markers (43/111, 39%) than did those with benign hepatitis(More)
To assess hepatitis C virus (HCV) incidence rates and identify determinants of infection among hemodialysis patients, a multicenter study was conducted in 58 units in ITALY: An initial seroprevalence survey was conducted among 3,492 patients already on hemodialysis therapy as of January 1997 and among an additional 434 patients who began dialysis up to(More)
To establish the mechanism of progression to chronicity of the HBsAg-associated delta infection, serum hepatitis B virus and delta markers were tested in five babies born to HBsAg-positive mothers with anti-delta, in 42 follow-up patients with acute hepatitis B virus and delta hepatitis, and in collections of sera from 8 HBsAg carriers with anti-delta.(More)
Hepatocellular carcinoma (HCC) is the fifth most frequent cancer in the world and a common occurrence in patients with liver cirrhosis in western and North American countries. Ultrasound screening is a powerful technique for HCC diagnosis, whereas the only available serologic test, alpha-fetoprotein, has poor reliability. It has been reported that the(More)
The prevalence of antibodies against hepatitis C virus (HCV) was assessed in 246 hemodialysis patients who attended a dialysis unit in Bari, using a recombinant enzyme immunoassay test (Abbot Lab.). Fifty-six (22.8%) sera were reactive to anti-HCV. The reactivity was confirmed in 46 specimens (18.7%) using the Abbott EIA HCV neutralization test. The(More)
Serum concentrations of alpha-foetoprotein (AFP) were measured sequentially by radioimmunoassay in 32 patients with fulminant hepatitis and coma, 22 of whom died. Levels were significantly elevated in 100% of patients who survived and in 7 out of 22 patients (38.5%) who died (P = less than 0.005). In the survivors the rise of AFP levels was found early(More)
To assess the epidemiology of infection with the delta agent associated with hepatitis B virus, sera from 1314 carriers of the hepatitis B surface antigen (HBsAg) and 687 patients with hepatitis B collected in 1978-1981 from different regions of Italy were tested for delta antigen and antibody to the antigen (anti-delta), and the characteristics of(More)
