  • Title: Helicobacter pylori link to pernicious anaemia.
    Author: Desai HG, Gupte PA.
    Journal: J Assoc Physicians India; 2007 Dec; 55():857-9. PubMed ID: 18405134.
    Abstract:
    An immunological classification of chronic gastritis based on the detection of Helicobacter pylori (H. pylori) antibody, parietal cell antibody, intrinsic factor antibody, is reported. H. pylori chronic gastritis, slowly progresses to atrophic gastritis, in the majority of patients; in a few patients, with genetic susceptibility to form intrinsic factor antibody, it progresses to pernicious anaemia. In majority of patients of pernicious anaemia, H. pylori gradually disappears from the gastric mucosa, on development of intestinal metaplasia in them. Atrophic gastritis results from H. pylori or non H. pylori. H. pylori infection is diagnosed in the presence of H. pylori in the gastric mucosal biopsy and/or H. pylori antibody (IgG) in the serum. The presence of the genetic factor (intrinsic factor antibody) is essential for the diagnosis of pernicious aneamia. Pernicious anaemia patients without intrinsic factor antibody, should be correctly diagnosed as atrophic gastritis, in view of the absence of the genetic factor (intrinsic factor antibody) in them.
