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.

The extent to which absorption of B12 is compromised, whether partial or complete and whether absorption is totally abrogated or whether it relates only to poor bioavailability of food B12 is also important. This assignation has deep historical roots, going back to the earliest recognition of the disease that acquired the eponymic title of Addisonian pernicious anemia following the somewhat vague description by the Guys Hospital physician, Thomas Addison, of a very remarkable form of general anemia occurring without any discoverable cause whatsoever. It was the astute clinical observations of Richard Cabot, William Osler, and others that brought the picture of the syndromic disease with its classical triad of associated jaundice, glossitis, and myeloneuropathy into sharper focus, as nicely recorded in William Castles historical review of the disease.1 Coller,2 in his commentary to mark the 70th anniversary of Blood, wrote: The most dramatic and far reaching event in hematology in the United States in the pre-Blood period was Minot and Murphys 1926 report that feeding liver to patients with pernicious anemia could cure this otherwise fatal disorder.

The folate product tetrahydrofolate regains a one-carbon methylene group through the serine hydroxymethyltransferase (SHMT) reaction, and the resulting methylenetetrahydrofolate is essential for conversion of deoxyuridine to thymidine in the thymidylate synthase (TS) reaction. In B12 deficiency, folate becomes trapped as methylTHF. Doctor told me that chest x-ray report is good and he just told I have low vitamin B12 level and I have bacteria in stomach. There is well-described evidence in the early literature that amounts of folic acid exceeding 1 mg daily given to patients with pernicious anemia were fraught with deleterious outcome.3,8 Although at first ameliorating hematological features of the disease, even at times with temporary improvement in neurological symptoms, continued administration of folic acid would precipitate or aggravate neurological complications, usually with subsequent recurrence of the anemia.8,43 Linked to these observations are reports of dissociation between neurological and hematological manifestations in B12-deficient patients6 as well as an inverse correlation between the degree of anemia and the severity of neurological involvement.44,45 There is some evidence that this relationship might be related to higher serum folate concentrations in patients with exclusively or predominantly neurological manifestations.44 More recently, and occurring in the wake of national folic acid fortification programs designed to reduce neural tube defect pregnancies, there have been several reports from longitudinal population studies that individuals with low serum B12 levels, who had associated high serum folate levels, had significantly higher levels of methylmalonic acid (MMA) and Hcy and were more likely to show cognitive decline and have lower hemoglobin concentrations than those with low B12 but without high serum folate.46-48 Moreover, individuals with low serum B12 and high serum folate had depressed levels of holotranscobalamin (holoTC), indicating an apparent depletion of circulating active B12 when serum folate was high.48 A report that the prevalence of anemia in patients with low B12 levels before and after the introduction of folic acid fortification was unchanged argues against the proposition that food fortification may have caused an increase in masking the hematological complications of B12 deficiency.49 However, it is possible that if there is any deleterious effect of folate in B12-deficient persons, this occurs only in individuals consuming amounts of folate well in excess of the recommended safe upper limit.8.

Plasma bilirubin is increased,58 as is serum lactic dehydrogenase (LDH),59 with LDH-1 predominating over LDH-2.60 Serum AST levels are, however, often normal.61 There is an increase in serum erythropoietin levels, but the increase is relatively modest, compared with other anemias of similar severity.62 Another feature arising from the ineffective erythropoiesis is a block in iron utilization, resulting in increased serum iron and ferritin levels,63 but with increased levels of soluble serum transferrin receptor, presumably related to hemolysis.64 Corresponding to the increase in LDH, there may be an increase in serum muramidase caused by increased granulocyte turnover.65, Although often used as the first-line screening test for B12 deficiency, serum B12 measurement used in isolation has a generally poor sensitivity and specificity for reliable detection of B12 deficiency.4,5 A low serum B12 level does not always indicate B12 deficiency, and a serum B12 within the reference range does not always connote normalcy.

Assuming that the lowest possible MMA level is consistent with optimal well-being, a large segment of the population may exist in a state of precarious B12 balance, as evidenced by the fact that concentrations of serum MMA leveled off to a nadir in healthy individuals consuming 4 to 7 g B12 daily.98 One of the possible implications of this finding is that individuals consuming less B12 may have a narrow margin of safety in the event that they were to develop any condition that further compromised their state of B12 repletion.
