HHS Vulnerability Disclosure, Help In the case of chemical inactivation of B12 by nitrous oxide, depending on the frequency and duration of its use and the state of B12 reserves, deficiency can develop either suddenly or insidiously.22,23, Severe and mild categories of B12 deficiency, The causes of mild B12 deficiency, on the other hand, involve either a disruption of the ability to render natural dietary B12 bioavailable or a primary dietary lack of B12 that is obtained among unsupplemented vegans or, to a lesser extent, among vegetarians.51 There are several conditions that disrupt the normal processes, as discussed in the review by Nielsen et al12 and depicted in Figure 1, whereby food B12 is rendered bioavailable for absorption through the physiological intrinsic factor-cubam receptor pathway (Table 1).

Deficiency causes megaloblastic anemia, damage to the white matter of the spinal cord and brain, and peripheral neuropathy. 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. 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 most instances, however, it would be prudent to top up a B12-deficient patient through parenteral injection before switching to the oral route for maintenance, with due vigilance concerning compliance, particularly in the elderly.
