Complete cure of urinary and faecal incontinence after intravenous vitamin B12 therapy in a patient with post-gastrectomy megaloblastic anaemia.
The case of a 59-year-old Japanese woman with post-gastrectomy megaloblastic anaemia having urinary and faecal incontinence and paraesthesia in four extremities is described. While the haematological abnormalities were improved by administration of a total dose of 17 mg of intramuscular mecobalamin, the neurological abnormalities remained unchanged. Five months later, a total dose of 7.5 mg of mecobalamin was injected intravenously over a period of 5 weeks, although the serum level of vitamin B12 was greater than 1180 pmol l-1. Immediately after initiation of the therapy, the urinary and faecal incontinence were gradually improved, and were completely cured within 2 months. The peripheral neuropathy was also ameliorated. The effectiveness of intravenous vitamin B12 injection for the neurological abnormalities due to vitamin B12 deficiency is emphasized.
