The relationship between unexplained elevated serum markers in triple test, uterine artery Doppler measurements and adverse pregnancy outcome.
OBJECTIVE
To investigate the relationship between adverse pregnancy outcomes and unexplained elevations of second trimester maternal serum human chorionic gonadotropin (hCG), alpha fetoprotein (AFP) levels and uterine artery Doppler measurements.


METHODS
A total of 144 women between 16-20 weeks of gestation that applied to our clinic for triple test were enrolled into the study. Study group consisted of 84 pregnant women with hCG and/or AFP levels > or =2 MoM. Control group comprised of 60 pregnant women with hCG and AFP levels <2 MoM. Study group was further subdivided into 3 subgroups: Subgroup I; only AFP> or =2 MoM (n=30), subgroup II; only hCG > or =2 MoM (n=64) and subgroup III; both AFP and hCG > or =2 MoM (n=10).


RESULTS
Operative delivery rate (p = 0.0017), overall complication rate (p=0.0002), bilateral early diastolic notch presence rate (p = 0.015) were high and mean birth weight was low (p=0.045) in the study group. In subgroup I patients, low birth weight [LBW] (p = 0.0008), preterm delivery (p = 0.0001), preeclampsia (p = 0.003) and preterm premature rupture of membranes [PPROM] (p = 0.012) rates were high. In subgroup II patients, only small for gestational age baby [SGA] (p = 0.016) rate was high. In subgroup III patients LBW (p = 0.009), preterm delivery (p = 0.0001) and PPROM (p = 0.01) rates were high. According to Doppler velocimetry studies, bilateral early diastolic notch presence rate was high (p = 0.015) in the study group.


CONCLUSIONS
Patients with high AFP levels and bilateral uterine artery diastolic notch presence, are candidates for pregnancy complications and these groups of patients should be followed up more intensively.
