Helicobacter pylori and type 1 diabetes mellitus: Possibility of modifying chronic disease susceptibility with vaccinomics at the anvil

Abstract

The human gastric pathogen, Helicobacter pylori, colonizes more than 50% of the world population and is a well-known cause of peptic ulcer disease. H. pylori has been epidemiologically linked to various other diseases, among which its putative link with certain complex diseases such as type 1 diabetes mellitus (T1DM) is of interest. Although antibiotic resistance is a significant clinical problem in H. pylori infection control, the exact cause and much of the underlying mechanisms of T1DM are not clearly understood. In addition, commensal microflora, gut-adapted microbial communities, and plausible roles of some of the chronic human pathogens add an important dimension to the control of T1DM. Given this, the present review attempts to analyze and examine the confounding association of H. pylori and T1DM and the approaches to tackle them, and how the emerging field of vaccinomics might help in this pursuit. © Copyright 2011, Mary Ann Liebert, Inc.
