Impaired 1,25-dihydroxyvitamin D production in pregnancy-induced hypertension.

Abstract

The aim of the study was to evaluate the calcium metabolism in pregnancy-induced hypertension. Fifty-three women with pregnancy-induced hypertension were studied and the control groups comprised 20 women with uncomplicated pregnancies in the third trimester and 51 non-pregnant women, respectively. The mean serum concentrations of 1,25-dihydroxyvitamin D in women with pregnancy-induced hypertension was low (38.6 +/- 21.4 pg/ml) compared to women with uncomplicated pregnancies (91.0 +/- 18.2 pg/ml), but comparable to levels in non-pregnant women (32.2 +/- 11.9 pg/ml). Mean serum levels of PTH and ionized calcium were comparable in women with pregnancy-induced hypertension and women with uncomplicated pregnancies. In conclusion, the calcium metabolism in pregnancy-induced hypertension was changed compared to uncomplicated pregnancies with respect to the serum concentration of 1,25-dihydroxyvitamin D.
