Hypochlorhydria (Low Stomach Acid): Symptoms, Tests, Treatment The essential role for both flaA and flaB in establishment of persistent colonization has been previously demonstrated by Eaton et al., who showed that aflagellate H. pylori strains only transiently colonized gnotobiotic piglets.59 Ultrastructural studies have demonstrated that the H. pylori flagellum is cloaked by a sheath that is an extension of the bacterial outer membrane, which likely protects the acid-labile flagellar structure from gastric contents.62 Similar to urease production, motility is required for persistent infection and McGee and colleagues have reported that FlbA, a component of the flagellar secretion apparatus that regulates flagellar biosynthesis, also mediates urease activity;63 thus, FlbA may couple urease production and motility, bacterial phenotypes that are necessary for the establishment and maintenance of gastric colonization. The normal human stomach has a pH which can range from approximately 1-3 but is usually closer to 2.

This increase corresponds with a reciprocal decrease in gastric acid output.51 Demonstration that administration of recombinant IL-1 receptor agonist normalizes acid output implicates IL-1 as a key modulator of acid secretion.51 Host polymorphisms associated with increased expression of IL-1 have been linked with increased risk for atrophic gastritis and gastric adenocarcinoma.5256 High expression alleles of another proinflammatory cytokine with acid-suppressive properties, TNF-, are also associated with an increased risk for gastric cancer.53,55, To facilitate locomotion within gastric mucus and to counteract peristalsis, H. pylori possesses five or six polar flagella that are comprised of two major structural subunits: a 53kDa FlaA and a 54kDa FlaB.57,58 The genes encoding these two flagellins are located at distant sites on the H. pylori chromosome and are transcriptionally regulated by different promoters.57,59 Expression of flaB and a gene encoding a component of the flagellar basal body export apparatus (flhA), peaks early during the bacterial growth phase and precedes expression of flaA.60 Flagellin-dependent motility is also regulated at a post-transcriptional level by an H. pylori bicistronic operon comprised of neuA, encoding a cytidyl monophosphate-N-acetylneuraminic acid synthetase, and flmD, which encodes a putative glycosyl transferase gene.61 Inactivation of flmD results in a motility-defective H. pylori mutant that is incapable of glycosylating FlaA.61.

Acute ingestion of H. pylori in humans leads to transient hypochlorhydria,31,32 but in untreated hosts, microbial-dependent inhibition of acid secretion resolves within several months and intraluminal pH decreases to within the normal range.32 In some individuals, acid production continues to increase, which is likely to result from a compensatory rise in serum gastrin and fall in mucosal somatostatin levels induced by gastric inflammation.3336, Table 76.1.
