MARTINEZ MARIN, Julián David; HENAO RIVEROS, Sandra Consuelo  y  REY TOVAR, Mario Humberto. Levels of vitamin B12 in colombian patients with chronic atrophic gastritis. Rev Col Gastroenterol [online]. 2010, vol.25, n.3, pp.261-264. ISSN 0120-9957.

We present a group of 75 Colombian adults who were diagnosed with chronic atrophic gastritis in accordance with the Sydney criteria. 28% of the group had vitamin B12 deficiencies: 9% were diagnosed with Pernicious anemia. Hemoglobin and mean corpuscular volume were not correlated with vitamin B12 deficiency. We found no statistical association of vitamin B12 deficiency with gender, patients over 60 years of age, or the presence of Helicobacter pylori (H. pylori). The average age of patients with vitamin B12 deficiency or pernicious anemia is less than that traditionally reported for these diseases

Palabras clave : Vitamin B12; chronic gastritis; atrophy; pernicious anemia.
