| Pernicious anemia is one of the most common causes of cobalamin deficiency. |
| It was reported that cobalamin had potent superoxide scavenging ability. |
| Folic acid, pyridoxine, and cobalamin are known to reduce homocysteine levels. |
| The B vitamins consist of thiamin, riboflavin, niacin, pyridoxine, folic acid, pantothenic acid, biotin, and cobalamin. |
| This neuropathy is very similar to that in cases of pernicious anaemia, which is also due to a deficiency of cobalamin. |
| A low cobalamin concentration had been noted several years earlier in the 57-year-old propositus, for which she received intermittent cobalamin injections. |
