OBJECTIVE: Although, oral replacement for vitamin B12 deficiency has been proved to be effective in adults, it is mainly treated with parenteral therapy. There are only few studies on oral replacement therapy of vitamin B12 with children. Therefore, we aimed to compare the efficacy of oral treatment with intramuscular vitamin B12 injections in pediatric population.
METHODS: Children with serum cobalamin concentrations less than 300 pg/mL, were treated either with the parenteral therapy or with oral vitamin B12. The primary and secondary outcomes of the study were the normalization of serum vitamin B12 and hemoglobin at first month, respectively.
RESULTS: Post-treatment vitamin B12 values were significantly higher than pre-treatment values (p-value <.001). Vitamin B12 increased from 183.5 ± 47 pg/mL to 482 ± 318.9 pg/mL in the oral and from 175.5 ± 42.5 pg/mL to 838 ± 547 pg/mL in the parenteral treatment arm (p-value <.001). Before treatment, 82 children had anemia according to age and gender. After treatment, 14/41 and 8/41 patients still had anemia at the first month of treatment in the parenteral and oral arms, respectively. The number of patients who still have anemia at the end of the 1st month of treatment did not significantly changed in the parenteral and oral treatment groups (p-value = .44).
CONCLUSIONS: In this study, both oral and parenteral formulations were shown to be effective in normalizing vitamin B12 levels. We suggest that oral formulations may be considered to be safe as a first line treatment for vitamin B12 deficiency in children.
