Inverse association between Helicobacter pylori infection and allergic rhinitis in young Japanese.

Background And Aim: The prevalence of allergic disorders, including asthma, atopic dermatitis, and allergic rhinitis has been increasing, and the prevalence of Helicobacter pylori (H. pylori) infection has been decreasing. Chronic bacterial infection during childhood is reported to protect the development of allergic diseases.

IL-17 is involved in Helicobacter pylori-induced gastric inflammatory responses in a mouse model.

Background: Helicobacter pylori (H. pylori) is the major cause of chronic active gastritis and peptic ulcer disease. Recent studies have shown that H.

[A case of miliary tuberculosis complicating acute Q fever].

A 73-year-old man was admitted with fever and abnormal liver function test. After admission, his fever persisted in spite of administrating a variety of antibiotics. He was diagnosed as acute Q fever on the basis of a high titer of IgM antibodies against phase II Coxiella burneti.

Influence of Helicobacter pylori infection on iron accumulation in hepatitis C.

Goal: Iron may play a role in the pathogenesis of chronic hepatitis C. Helicobacter pylori (Hp) infection was recently associated with iron-deficiency anemia. We examined the influence of Hp infection on hepatic iron accumulation in hepatitis C.

[A case of pancreatic intraductal papillary-mucinous carcinoma with penetration to the stomach and splenic abscess].

We report the case of an 80-year-old man given a diagnosis of pancreatic intraductal papillary-mucinous carcinoma (IPMC) and early gastric cancer. He refused surgery, therefore endoscopic mucosal resection (EMR) for gastric cancer and careful observation were performed. Penetration of the IPMC to the stomach was observed 3 months later.

Vector potential of cockroaches for Helicobacter pylori infection.

Objectives: The routes of human infection with Helicobacter pylori remain unclear. In the present study, we examined cockroaches as possible vectors for transmission of H. pylori.

Antimicrobial activity of essential oils against Helicobacter pylori.

Background: Helicobacter pylori is an important pathogen responsible for gastroduodenal diseases in humans. Although the eradication of H. pylori using antibiotics often improves gastroduodenal diseases, resistance to the antibiotics is emerging.

Helicobacter pylori infection in mice: Role of outer membrane proteins in colonization and inflammation.

Background & Aims: Mouse models of Helicobacter pylori infection have yielded variable results with respect to colonization and inflammation. We examined whether outer membrane proteins (OMPs) or the cag pathogenicity island (PAI) was responsible for some of this variability.

Methods: C57BL/6 mice received clinical H.
