Vitamin B12 deficiency anaemia associated with chronic atrophic gastritis – http://id.who.int/icd/entity/1276530307

Pernicious anaemia is associated with chronic atrophic gastritis, which is linked with autoantibodies directed against gastric parietal cells in approximately 90% of patients. A potential relation between susceptibility to infection with Helicobacter pylori, atrophic gastritis and low serum B12 levels has been suggested; secondary to a common variation in the FUT2 secretor gene, whose product is a mediator of Helicobacter pylori attachment to human gastric mucosa.
