Decreases in the number of lymphocytes and CD8+ cells and in the proportion of CD4+ cells, an abnormally high CD4/CD8 ratio, and suppressed NK cell activity were noted in patients compared with control subjects. Disruption of the mechanisms to render dietary B12 bioavailable all involve a failure of adequate gastric acid production, disrupting the proteolytic activity of peptic digestion.52 A similar failure of the digestive process applies in the case of chronic pancreatic disease,53 in which the release of B12 from salivary haptocorrin (HC) in the upper small intestine is disrupted through lack of bicarbonate and trypsin production.54 There are some less common causes of B12 deficiency that do not fit nicely into either category, such as infestation with the fish tapeworm, Diphyllobothrium latum, in which the degree of deficiency and hence its clinical severity can vary considerably.55, Two pathophysiologic processes contribute to the anemia resulting from B12 deficiency.
