Biomarkers of intrauterine growth restriction

Abstract

Intrauterine growth restriction (IUGR) is a serious clinical problem affecting about 10% of all pregnancies, and even up to 15% of all monochorionic twin pregnancies. This disorder is accompanied by strongly increased perinatal mortality. IUGR has multiple causes including maternal, fetal, placental, and environmental factors. Importantly, IUGR is associated with a number of negative effects exerted just after the birth, as well as during the later years of life. Despite multiple clinical trials conducted for many years, there is no reliable algorithm to diagnose the disease at an early stage, and lack of efficient therapy increases the risk of abnormal fetus development. In this short review, we present recent progress on potential IUGR biomarkers that could be determined during pregnancy and in the umbilical blood after delivery to provide more accurate diagnosis, prophylaxis and efficient treatment.
