Epidemiologic characteristics of infection in southeast Hungary.

Background: Epidemiologic studies have revealed a decrease in the prevalence of () infection in Western Europe.

Aim: To obtain data regarding the prevalence of in Csongrád and Békés Counties in Hungary, evaluate the differences in its prevalence between urban and rural areas, and establish factors associated with positive seroprevalence.

Methods: One-thousand and one healthy blood donors [male/female: 501/500, mean age: 40 (19-65) years] were enrolled in this study.

Genetic polymorphisms of NOD1 and IL-8, but not polymorphisms of TLR4 genes, are associated with Helicobacter pylori-induced duodenal ulcer and gastritis.

Background: Intracellular pathogen receptor NOD1 is involved in the epithelial cell sensing Helicobacter pylori, which results in a considerable interleukin (IL)-8 production. The aim of this study was to evaluate the relationship between NOD1 and IL-8 genetic polymorphisms and the development of H. pylori-induced gastritis and duodenal ulcer (DU), as compared with TLR4 polymorphisms.

Genetic polymorphism of interleukin-8 (IL-8) is associated with Helicobacter pylori-induced duodenal ulcer.

Background And Aims: Helicobacter pylori infection almost invariably causes chronic gastritis, but only a proportion of the infected subjects develop peptic ulcers. The local inflammation associated with H. pylori infection is characterized by an increased production of the proinflammatory cytokines IL-1-B, IL-6, IL-8 and TNF-alpha.

Helicobacter pylori-induced immunological responses in patients with duodenal ulcer and in patients with cardiomyopathies.

The interaction between the bacteria and the host is a key factor determining the clinical consequences of H. pylori infection. The immune system plays an important role in either promoting or preventing the disease.

Local and peripheral cytokine response and CagA status of Helicobacter pylori-positive patients with duodenal ulcer.

The mucosal production of TNF-alpha, IL-6, IL-8, IL-10 and nitrotyrosine was investigated in H. pylori-positive patients with duodenal ulcer (DU). The concentrations of these cytokines in gastric antrum mucosal specimens from patients infected with H.

[Studying the effect of enzyme replacement in chronic pancreatitis].

Authors studied the effect of Neo-Panpur in chronic pancreatitis patients with moderate or severe exocrine pancreatic insufficiency. Patient's complaints, laboratory parameters and pancreatic function were also registered. Indications of pancreatic substitution therapy and the advantages of Neo-Panpur treatment are also discussed.

[Angioimmunoblastic lymphadenopathy and Hodgkin's disease].

In the lymph node biopsy specimen of a 80 year old male patient with clinical symptoms of malignant lymphoma histologically angioimmunoblastic lymphadenopathy have been diagnosed (AIBLP). In the second biopsy specimen obtained several weeks later histological picture of Hodgkin's disease (Hd) of the mixed cellularity type was found. In the first biopsy specimen micro-Sternberg -Reed-cells (micro-S-R) were also observed.
