Resum:
OBJECTIVES: We investigated whether early pregnancy hyperhomocysteinemiais a biomarker of pathological fetoplacental Doppler or intrauterine growth retardation (IUGR). METHODS: A nested case-control study with a group of cases based onpopulation birthweightcurves (IUGR-Pop) and another group with customisedcurves(IUGR-Cus) was performed. RESULTS: 43 cases were matched with 161 controls in the IUGR-Pop group, and 145 cases with 63 controls in the group IUGR-Cus. Hyperhomocysteinemia was defined as plasma homocysteine above the 90th percentile and was associated with reduced birth weight, increased resistance of the uterine arteries, increased risk of pathological umbilical Doppler (OR = 3.1), IUGR-Poprisk (OR=8.2) andIUGR-Cus risk (OR=4.9). CONCLUSION : Early pregnancy hyperhomocysteinemiais associated with reduced birth weight, altered feto-placental Doppler function and increased IUGR risk in the two populations studied .
