“…In one of them the mother had vitamin A deficiency during pregnancy. Although in the patient reported here the vitamin A status was documented for the first time at 16 weeks' gestation, it is very unlikely that it would have been normal during the first weeks of pregnancy as under normal physiological conditions the plasma vitamin A level does not decrease during pregnancy [10]. From the 12th week of gestation onwards, the mother was supplemented with vitamins, but it took until 24 weeks' gestation for vitamin A levels to reach normal values.…”

Já nas concentrações plasmáticas médias das mães em ambos os grupos, verificou-se que estas eram superiores às de seus recém-nascidos, fato semelhante ao descrito anteriormente na literatura 7,11,15,25 .…”
