It has been suggested that vitamin B12 (vit.B12) plays an important role in immune system regulation, but the details are still obscure. Both are caused by impaired DNA synthesis that results in a prolongation of the S phase of the cell cycle16 and causes maturation arrest.17 Prolongation of the cell cycle is associated with delayed migration of the DNA replication fork and the annealing of DNA fragments synthesized from the lagging strand.18 The retardation of DNA replication in megaloblasts arises from failure of the folate-dependent conversion of deoxyuridine to deoxythymidine. 9. Epub 2008 Feb 19.

In an adult, the total body B12 store is 3 to 5 mg, and the recommended daily intake (RDI) is 2.4 g.8 Natural food sources of B12 are restricted to food of animal origin. An extreme example of this is seen in a B12-deficient patient with normal serum B12 levels who has an underlying myeloproliferative disease with high HC levels.66 In almost 50% of patients with low vitamin B12 levels, levels of the biochemical markers, MMA and Hcy, were found to be normal, and these patients had no hematologic or neurologic response to B12 replacement therapy, suggesting that the low B12 values were false positive results.67 Serum B12 levels are usually normal in functional B12 deficiency, resulting from exposure to nitrous oxide, which chemically inactivates the methylcobalamin at the active site of the methionine synthase during its catalytic cycle.68 Serum B12 levels are also usually normal in TC deficiency, and inborn errors of cobalamin metabolism.69 Conversely, serum B12 levels may be low in the presence of normal tissue B12 in vegetarians,70 in subjects taking megadoses of ascorbic acid,71 in inherited benign HC deficiency,72,73 and in a substantial proportion of patients with megaloblastic anemia resulting from folate deficiency (30%).4, The B12 bound to HC comprises 70% to 90% of the total plasma B12, yet is unavailable for cellular delivery.

In B12 deficiency, folate becomes trapped as methylTHF. Lack of a validated B12 absorption test hampers accurate diagnosis of pernicious anemia as the cause of B12 deficiency and clinical investigations related to all causes of B12 malabsorption.92 One possible test that shows promise, the Cobasorb test, is based on the measurement of the change in holoTC following oral administration of nonradiolabeled cobalamin.82,93,94 An alternative approach has been described using accelerator mass spectrometry to quantify 14C in the blood following an orally administered dose of [14C]-cyanocobalamin.95, In absence of any test for B12 absorption, definitive diagnosis of pernicious anemia is problematic and depends on the demonstration of circulating antibodies to intrinsic factor and gastric parietal cells.
