We suggest that patients should be followed up for some time after testing for severe hematological diseases.

The causes that are listed as severe usually involve disease processes that disrupt some aspect of the physiological pathway for B12 absorption comprising intrinsic factor and the cubam receptor in the terminal ileum.

However, as ever more sensitive methods were developed to assess subtle degrees of deficiency of the vitamin,4,5 it became clear that the effects of B12 deficiency were not restricted to the hematopoietic system but were often overshadowed by neurological complications and were sometimes entirely absent.6 Just as folate deficiency is associated with effects beyond anemia,7 B12 deficiency also can be associated with nonhematological complications, including increased risk of neural tube defect pregnancy, cognitive impairment, osteopenia, and vascular occlusive disease, perhaps attributable to the accumulation of homocysteine (Hcy) that occurs in B12 deficiency.3 Even so, because the most conspicuous manifestations of established B12 deficiency affect the blood and bone marrow and are a leading cause of macrocytic and megaloblastic anemia, it is ultimately the practicing hematologist who remains front and center of the clinical diagnosis and management of patients with suspected or confirmed B12 deficiency. 2022 Nov 24. doi: 10.1007/s10072-022-06518-6.
