Ghrelin is a new gastric peptide involved in food intake control and growth hormone release. We aimed to assess its cell localisation in man during adult and fetal life and to clarify present interspecies inconsistencies of gastric endocrine cell types. A specific serum generated against amino acids 13–28 of ghrelin was tested on fetal and adult gastric(More)
Objective: Intrahepatic cholangiocarcinoma (ICC) is a rare type of primary liver cancer (PLC) arising from intrahepatic bile ducts. We carried out a case–control study to assess the association between ICC and hepatitis B and C virus (HBV and HCV) infections, alcohol intake, and hepatolithiasis in Brescia, North Italy. Methods: Among 370 subjects with(More)
OBJECTIVE To determine the effect of eradicating Helicobacter pylori infection on the course of low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. DESIGN Prospective cohort study. SETTING University internal medicine clinics, a referral oncology center in southern Switzerland, and a gastroenterology referral center in northern Italy.(More)
BACKGROUND & AIMS The majority of patients with Helicobacter pylori infection have autoantibodies cross-reacting with gastric antigens. In this study, the relation between autoantibody status, histopathology of body mucosa, and antigenic profile of H. pylori was investigated. METHODS One hundred patients were examined for H. pylori infection, body(More)
We aimed to assess the occurrence of ghrelin, a new gut hormone, in endocrine growths of the stomach. In addition, since ghrelin has been detected in other gut derivatives during adult and/or fetal life, we also studied endocrine tumours of the pancreas, intestine and lung. A specific serum generated against amino acids 13–28 of ghrelin was tested on 16(More)
Recently, it has been shown that the lipopolysaccharide (LPS) O antigen of Helicobacter pylori contains Lewis x (Lex), Lewis y (Ley), or both Lex and Ley antigens. We applied a serotyping method for H. pylori by an enzyme-linked immunosorbent assay with monoclonal antibodies (MAbs) specific for these antigens and the related fucosylated H type 1 (H1)(More)
Knowledge on the role of Helicobacter pylori (HP) infection is continually evolving, and treatment is becoming more challenging due to increasing bacterial resistance. Since the management of HP infection is changing, an update of the national Italian guidelines delivered in 2007 was needed. In the III Working Group Consensus Report 2015, a panel of 17(More)
We performed a case-control study to assess the role of hepatitis B virus (HBV), hepatitis C virus (HCV), GB virus C/hepatitis G virus (HGV), TT virus, alcohol intake, and tobacco smoking as risk factors for hepatocellular carcinoma (HCC) in the presence or absence of cirrhosis. We prospectively recruited 174 patients with a first diagnosis of HCC admitted(More)
The effect of eradication of Helicobacter pylori on early stage gastric low-grade MALT lymphoma in 76 patients with follow-up of at least 1 year (12-63 months, mean 28) is reported. No regression was found in five cases after 12-48 months. In one case surgical resection detected the involvement of perigastric lymph nodes overlooked by endoscopic(More)
