Long-term outcome in children with nutritional vitamin B12 deficiency

Abstract

All the patients achieved full hematologic recovery within 1 month of treatment onset. Neurological symptoms resolved following B12 administration; however, during long-term follow-up ranged from 17% to 37% of the tested patients had persistent VEP; BERA, and Denver II abnormalities. Neurological symptoms resolved following B12 administration; however, during long-term followup 33% of the patients had persistent VEP, BERA, and Denver II abnormalities. As such, clinicians should continue to follow-up such patients even after hematologic and clinical improvement are obtained in order to assess their neurologic status.
