A 58-year-old woman, who had undergone total gastrectomy for early gastric cancer 9 years previously, visited the outpatient clinic complaining of progressive difficulty in walking for 15 d. Laboratory examinations showed macrocytic anemia and a decreased serum vitamin B12 concentration and increased serum concentrations of folate, vitamin E and copper. Magnetic resonance imaging showed multifocal high signal intensities along the posterior column of the cervical and thoracic spinal cord. Treatment consisted of intramuscular injections of vitamin B12 for 7 d, which increased her serum level of vitamin B12 to normal...

Many patients with pernicious anemia are treated with lifelong intramuscular (IM) vitamin B12 replacement. As early as the 1950s, there were studies suggesting that oral vitamin B12 replacement may provide adequate absorption. Nevertheless, oral vitamin B12 replacement in patients with pernicious anemia remains uncommon in clinical practice. The objective of this review is to provide an update on the effectiveness of oral vitamin B12 for the treatment of pernicious anemia, the recommended dosage, and the required frequency of laboratory test and clinical monitoring...

BACKGROUND: A combined supplement of vitamins B9 and B12 was reported to increase milk and milk component yields of dairy cows without effect on feed intake. The present study was undertaken to verify whether this supplementation positively modifies the pathways involved in milk and milk component synthesis. Thus, by studying the transcriptome activity in these tissues, the effect of supplements of both vitamins on the metabolism of both liver and mammary gland, was investigated. For this study, 24 multiparous Holstein dairy cows were assigned to 6 blocks of 4 animals each according to previous 305-day milk production...

Elevated levels of total homocysteine impair endothelial dysfunction and increase thrombosis. Homocysteine is causal in animal models, and in human studies, elevated total homocysteine is significantly associated with carotid atherosclerosis, lacunar infarction, and markedly increased risk of stroke in atrial fibrillation. Because two of the early large trials of B vitamin therapy (Vitamin Intervention for Stroke Prevention and the Norwegian Vitamin Study) did not show any reduction of stroke, and the Heart Outcomes Prevention Evaluation 2 trial was mistakenly interpreted as not showing a reduction of stroke (because the authors could not think of a biological difference between stroke and myocardial infarction), there has been widespread pessimism regarding treatment to lower total homocysteine for stroke prevention...

Chronic arsenic toxicity is a serious environmental health problem across the world. Bangladesh and India (particularly the state of West Bengal) are the worst affected countries with such problem. The present study reports plasma-aminothiols (p-aminothiols) like L-cysteine (L-Cys), cysteinyl glycine (Cys-gly), total homocysteine (t-Hcy) and glutathione (GSH) status, and the inverse relationship of t-Hcy with B-vitamins (B1, B6, B9 and B12) in arsenic exposed population of West Bengal, India. Reverse phase HPLC was used to measure p-aminothiols and serum B-vitamins in different arsenic exposed population...

A 47-year-old woman developed severe bilateral visual loss 4 years after a Roux-en-Y gastric bypass and 24 years after vertical banded gastroplasty. Her serum copper level was 35 μg/dL (normal, 80-155 μg/dL). She was prescribed elemental copper tablets. Because her methylmalonic acid was slightly elevated, she received vitamin B12 injections as well. Five weeks later, she reported that her vision had improved and, at 10 months, her vision had recovered from 20/400 bilaterally to 20/25 in each eye. This case highlights the importance of checking copper levels in addition to the "more routine" vitamin levels, such as B1, B6, B12, E, and serum folate in patients with suspected nutritional optic neuropathy after bariatric surgery, particularly if it involved a bypass procedure...

PURPOSE: A vitamin B12 supplement is required in pemetrexed single agent therapy. Intramuscular administration is the method of choice; however, oral administration is simpler and easier and may be sufficiently effective. We conducted a Phase II study to evaluate the safety of oral administration of vitamin B12 in patients with advanced non-small cell lung cancer who received pemetrexed single agent therapy. METHODS: Folic acid and vitamin B12 were given orally for ˃ 1 week before pemetrexed administration...
