Vitamin D Deficiency and Its Clinical Results in Preeclamptic Mothers and Their Babies.

INTRODUCTION

Vitamin D deficiency during pregnancy may lead to many health problems by negatively affecting the metabolism of the newborn and the mother, such as infantile rickets, poor fetal and neonatal growth and development, gestational diabetes, and preeclampsia. We aimed to investigate the levels and clinical results of vitamin D in preeclamptic mothers and their babies.

METHODS

The study group consisted of 42 preeclamptic mothers, and their babies diagnosed with preeclampsia according to the International Society for the Study of Hypertension in Pregnancy (ISSHP) criteria, while the control group consisted of 49 healthy mothers and babies with similar gestational age and birth weight. All pregnant women participating in the study were routinely taking 1200 IU of vitamin D3 daily supplements. The cord blood vitamin D level of both groups of newborns was measured and the results were statistically compared.

RESULTS

The birth week, weight, and height averages and APGAR score averages measured at the first minutes of the babies in the study group (preeclamptic mother babies) were statistically significantly lower than those of the babies in the control group (babies of healthy mothers) (p=0.001, p=0.001, p<0.001, p=0.004, respectively). Vitamin D and calcium levels of the mothers in the study group were lower than those of the mothers in the control group. When the infants were examined, only the level of vitamin D was statistically significantly lower in infants in the patient group (p<0.001, p<0.001, p=0.001, respectively).

CONCLUSION

There is consistent evidence of an association between low vitamin D concentrations and adverse preeclampsia outcomes. Since vitamin D deficiency is more common in preeclamptic mothers and their infants, higher-dose vitamin D supplementation than routine may be recommended to the patients.
