The prevalence of Helicobacter pylori infection in patients with gastric and duodenal ulcers - a 10-year, single-centre experience.

Introduction: Helicobacter pylori (H. pylori) occurs throughout the world and causes gastroduodenal diseases. There is data indicating a change in the prevalence of H.

Pegylated interferon Alfa-2b monotherapy and pegylated interferon Alfa-2b plus lamivudine combination therapy for patients with hepatitis B virus E antigen-negative chronic hepatitis B.

Forty-eight hepatitis B virus (HBV) E antigen-negative chronic hepatitis B patients received pegylated interferon alfa-2b either alone or with lamivudine for 48 weeks and were followed for an additional 24 weeks. At the end of follow-up, virological response rates (HBV DNA levels of <400 copies/ml) were similar in the monotherapy (24%) and combination therapy (26%) groups.

YMDD motif variants in inactive hepatitis B carriers detected by Inno-Lipa HBV DR assay.

Introduction: Mutations of hepatitis B virus (HBV) polymerase, especially occurring at the highly conserved YMDD region, are related to resistance to lamivudine. Although these mutations are frequently secondary to lamivudine use, they can also occur naturally. The aim of the present study was to determine the prevalence of YMDD variants that exist naturally in patients who are inactive HBV carriers.

Alanine aminotransferase deficiency in a hepatitis B surface antigen positive patient presenting with acute hepatitis.

This report presents a hepatitis B surface antigen positive case presenting with acute hepatitis and with findings of low serum alanine aminotransferase in contrast to very high levels of aspartate aminotransferase. A 64 year-old female patient was admitted to our hospital with fatigue and jaundice. Hepatitis B surface antigen was positive.

Diagnostic usefulness of carbohydrate antigen-125 in cancerous and noncancerous peritoneal effusions.

Carbohydrate antigen-125 (CA-125) is a tumor marker that has been used for differential diagnosis of peritoneal malignancies. The aim of the present study was to evaluate the diagnostic usefulness of simultaneous quantification of CA-125 in peritoneal fluid and serum for abdominal cancer cases and noncancer diseases. Noncancer disease group included cirrhotic patients (n=28) and spontaneous bacterial peritonitis (SBP) patients (n=11).

The role of serum leptin levels in chronic hepatitis C with steatosis.

Background/aims: Leptin has recently been suggested to play a role in the pathogenesis of hepatic steatosis and steatohepatitis in the absence of viral infection. The aim of this study was to evaluate whether leptin levels are associated with hepatic steatosis in chronic hepatitis C.

Methodology: Thirty-one patients (22 female, 9 male, mean age: 51 +/- 9) with histologically proven chronic hepatitis C were included in this prospective, controlled, observational, clinical study with blind outcome assessment.

Relationship between non-steroidal anti-inflammatory drug use and Helicobacter pylori infection in bleeding or uncomplicated peptic ulcers: A case-control study.

Background And Aims: Non-steroidal anti-inflammatory drug (NSAID) use has been closely associated with an increased risk of bleeding peptic ulcers, while the prevalence of Helicobacter pylori infection has been reported to be lower in bleeding ulcers than in non-bleeding ones. However, whether an interaction exists between NSAID use and H. pylori infection has not clearly been elucidated yet.

Effect of ursodeoxycholic acid on hepatic steatosis in rats.

Ursodeoxycholic acid (UDCA) has been shown to have hepatoprotective effects in various liver diseases. This drug has also been found to be effective in patients with nonalcoholic steatohepatitis, improving hepatic steatosis (HS) significantly. The aim of this study was to evaluate whether UDCA has an effect on both preventing and regressing HS in rats.
