Abstract

Methylmalonic acid and total homocysteine in plasma and serum have previously been used as indicators of intracellular cobalamin function in adults. To assess the usefulness of quantitation of these metabolites in the diagnosis of dietary cobalamin deficiency in infants, they were determined in plasma from 41 infants (aged 10-20 mo) on a macrobiotic diet and in 50 healthy group-matched omnivorous controls. In the macrobiotic infants, both methylmalonic acid and total homocysteine were markedly increased compared with controls (8-fold and 2-fold, respectively). Both metabolites showed an inverse relation to the plasma cobalamin level. The very low cobalamin content of the macrobiotic diet and low plasma cobalamin in macrobiotic infants makes an impaired cobalamin function likely in these infants. We therefore used dietary group as an independent indicator of cobalamin status. Different test parameters for cobalamin status were evaluated by comparing their ability to discriminate between the two dietary groups. Logistic regression analysis showed that methylmalonic acid followed by total homocysteine and cobalamin, in that order, were the strongest predictors of dietary group. Mean corpuscular volume and Hb had low discriminative power. We conclude that the determination of methylmalonic acid and total homocysteine represents a sensitive and specific test for the diagnosis and follow-up of nutritional cobalamin deficiency in infants. Furthermore, the finding of high methylmalonic acid and total homocysteine in plasma of most macrobiotic infants demonstrates a functional cobalamin deficiency in these subjects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
