Helicobacter pylori and functional dyspepsia: review of previous studies and commentary on new data.

What Is the Difference Between Helicobacter pylori-Associated Dyspepsia and Functional Dyspepsia?

Advances in basic and clinical research have revealed that Helicobacter pylori (H. pylori) infection plays an important role in the development of gastroduodenal dysmotility and hypersensitivity, as also in dyspepsia symptoms. In addition, recent studies have proposed an inflammation-immunological model for the pathogenesis of functional dyspepsia. Since H. pylori is the major microbe that prov...

Comparison of CD4+ and CD8+ T- lymphocyte in Helicobacter pylori-negative functional dyspepsia

Systematic review of the epidemiological evidence on Helicobacter pylori infection and nonulcer or uninvestigated dyspepsia.

BACKGROUND Previous studies have yielded conflicting results and substantial uncertainty about any independent association of Helicobacter pylori infection with dyspepsia, and about any benefits of antibiotic treatments for nonulcer or uninvestigated dyspepsia. OBJECTIVES To perform a systematic review of the literature to determine whether chronic infection with H pylori is relevant to nonul...

The Role of H. pylori CagA in Regulating Hormones of Functional Dyspepsia Patients

Helicobacter pylori (H. pylori, Hp) colonizes the stomachs of approximately 20%-80% of humans throughout the world. The Word Healthy Organization (WHO) classified H. pylori as a group 1 carcinogenic factor in 1994. Recently, an increasing number of studies has shown an association between H. pylori infection and various extragastric diseases. Functional dyspepsia (FD) is considered a biopsychos...

Refractory iron deficiency anemia and Helicobacter Pylori Infection in pediatrics: A review

Background Since the discovery of Helicobacter pylori, several clinical reports have demonstrated that H. Pylori infection has emerged as a new cause of refractory iron stores in children. We carried out a systematic literature review to primarily evaluate the existing evidence on the association between childhood H. Pylori infection and iron deficiency anemia (IDA) and secondly, to investigat...
