Polymorphic differences in genes involved in the complex repertoire that comprises the pathways of B12 absorption, assimilation, cellular metabolism, and plasma transport of the vitamin (Figure 1) are known to affect the susceptibility to develop B12 deficiency.32,33 Whether these genetic factors can also influence the disease phenotype in B12 deficiency is not well understood at this time. Ter Arkh. Between 1% and 4% of an oral dose of B12 is absorbed passively, even when the intrinsic factor-dependent pathway is abrogated.102 Consequently, oral replacement therapy with B12, which was used successfully in the past,103 has again come into vogue,104 because of convenience and cost.

This vitamin is needed to make red blood cells, which carry oxygen to all parts of your body. 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. FULL STORY. 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.
