Abstract: | This study was undertaken to determine the longitudinal changes of serum 1,25-dihydroxyvitamin D (1,25-(OH)(2)D) and insulin like growth factor I (IGF-I) levels at 20.7, 27.6, and 35.5 week periods of gestation in 40 pregnant women who remained normotensive (NT) and in 10 women who developed preeclampsia (PE). As compared with the first period, significant increases (P < 0.01) in maternal serum 1,25-(OH)(2)D and IGF-I were observed in the NT group. In the PE group, a similar increase in serum 1,25-(OH)(2)D was observed. In contrast, significant (P < 0.05) lower IGF-I levels were observed in the PE group at the moment of diagnosis. In addition a high incidence of subjects with low increase in IGF-I levels (
