The concentration of insulin-like growth factor-1 in pregnancies complicated by pregnancy-induced hypertension and/or intrauterine hypotrophy.

Objectives: The aim of the study was to compare Insulin-like Growth Factor-1 (IGF-1)concentration in pregnancies complicated by pregnancy-induced hypertension and/or intrauterine hypotrophy, and its correlation with maternal pressure and umbilical artery pulsatility and resistance indices.

Material And Methods: 65 pairs pregnant-newborn were included to four groups: I - control, II - PIH, III - Hypotrophy, IV - PIH and Hypotrophy. In the study we analyzed cord blood IGF-1 concentration, newborns antropometry, umbilical artery pulsatility and resistance indices and maternal pressure before delivery.

Results: The concentration of IGF-1 was the lowest in IV group of hypotrophic newborns from pregnancies complicated by pregnancy-induced hypertension. In this group of patients there was strong negative correlation between IGF-1 concentration and maternal systolic and diastolic pressure.

Conclusions: There is a strong negative correlation between IGF-1 concentration and maternal systolic pressure in group of hypotrophic newborns from pregnancies complicated by pregnancy-induced hypertension.
