Helicobacter pylori infection leads to an inflammatory response in 100% of infected individuals. The inflammatory cells which are recruited to the gastric mucosa during infection produce several pro- and anti-inflammatory cytokines including several cytokines in the interleukin-17 family. The anti-inflammatory cytokine, interleukin 25 (IL-25, also known as IL-17E), signals through a receptor, w...
background: it has been reported that several species of helicobacter colonize the biliary tract of animals and human, but their participation in hepatobiliary diseases are not established. this study is undertaken to determine if helicobacter genus members, especially with regard to h. pylori , could be detected in the bile and gallbladder diseases. methods: thirty-eight gallbladder tissues ...
BACKGROUND Helicobacter pylori (H. pylori) infection is very common worldwide, with varying frequency. According to data from epidemiological reports, a third of the population of children in Poland are infected with H. pylori before the age of 18. In recent years, a decrease in the incidence of H. pylori infection in both children and adults has been observed in many countries. OBJECTIVES Th...
OBJECTIVE To determine whether Helicobacter pylori is associated with infantile colic. DESIGN Case-control study. SETTINGS Local tertiary hospital in rural Gizan, Saudi Arabia. PARTICIPANTS A total of 55 patients with infantile colic who were 2 weeks to 4 months of age and who fulfilled modified Wessel criteria (ie, crying and fussy behavior) and a total of 30 healthy controls with no his...
Helicobacter pylori is the primary cause of peptic ulcer disease and an etiologic agent in the development of gastric cancer. H. pylori infection is curable with regimens of multiple antimicrobial agents, and antimicrobial resistance is a leading cause of treatment failure. The Helicobacter pylori Antimicrobial Resistance Monitoring Program (HARP) is a prospective, multicenter U.S. network that...
The prevalence of Helicobacter pylori is increased in healthcare workers and in intensive care nurses. Exposure to H. pylori from gastric secretions and faeces are probably the main sources of transmission to healthcare workers. Routine use of selective decontamination of digestive tract (SDD) in an intensive care unit suppresses H. pylori in critically ill patients. It was questioned whether t...
Foods with animal origins play a substantial role in the transmission of Helicobacter pylori. The present investigation was carried out to study the vacA and cagA genotypes status of H. pylori isolated from various types of meat samples. Two hundred and twenty meat samples were collected and cultured. H. pylori-positive strains were analyzed for the ...
Background: Until now, no study has been reported investigating the association between β-thalassemia minor and Helicobacter pylori (H. pylori) infection. This study was designed to compare H. pylori infection rate between β-thalassemia minor patients and healthy controls. Methods: A number of 100 β-thalassemia minor patients (50 males, 50 females) and 100 gender-matched healthy...
Introduction: Helicobacter pylori (H. pylori) is suggested to play a role in dyspepsia. The aim of this study was to assess the prevalence of H. pylori, in dyspeptic patients. Methods: This cross-sectional study was conducted on 850 patients with dyspepsia in Iran (2006-2007). The patients were selected using convenience sampling method. Data was collected using ROME III criteria questionnaire...
Development of a stool antigen immunoassay to detect Helicobacter pylori infection requires monoclonal antibody against the specific antigen. Alkylhydroperoxide reductase (AhpC) of Helicobacter pylori has been described as a specific and unique enzyme for H. pylori and therefore, both H. pylori AhpC and Anti-AhpC could be useful in the development of serologic and stool antigen tests, for detec...
