Granulomatous gastritis, iron deficiency, vitamin B12 malabsorption and immunoglobulin deficiency

Abstract
Summary: A 24-year-old male with recurrent iron deficiency anaemia was found to have a generalized reduction in his immunoglobulin levels, granulomatous gastritis and impaired vitamin B12 absorption corrected by Intrinsic Factor. There is discussion of the possibility that cell mediated mechanisms may have been involved in the cause of the vitamin B12 malabsorption.
