Recurrent anaemia in a patient with lymphocytic gastritis and vitamin B-12 deficiency

Lymphocytic gastritis is an idiopathic disease, characterized by intraepithelial infiltration of large numbers of T lymphocytes and often described in association with coeliac disease and Helicobacter pylori infection. Although usually associated with iron deficiency anaemia, there is no description on the association between lymphocytic gastritis and secondary vitamin B-12 deficiency anaemia. We describe a rare case of recurrent anaemia in a patient with lymphocytic gastritis reversed with vitamin B-12 replacement. (C) 2017 Pan-Arab Association of Gastroenterology.
