Abstract
Objective. Retrospective study of the results of the first-trimester combined screening for fetal trisomies with ultrasound and biochemical markers. Methods. In the period from February 2006 to July 2008, a total of 1112 pregnant-women underwent screening between the 10th and 14th gestational week. Individual risk for trisomies 21, 18 and 13, combining maternal age, ultrasonography (nuchal translucency, crown-rump length) and serum biochemical analytes (free -hCG, PAPP-A) was computed by means of licensed Typolog software. Concentrations of biochemical markers were determined by chemiluminiscent immunometric assay (IMMULITE). Both biochemical markers, as well as NT, were expressed as Multiples of the Median (MoM), based on the regressed medians of the corresponding gestational age in unaffected pregnancies. Results. All studied pregnancies were followed up to term. A total of 62 pregnant women were categorized as high-risk for trisomy 21, and 10 of them had also an elevated risk for trisomies 18/13, respectively. Four trisomies 21 and one trisomy 18 were detected through combined test and confirmed with prenatal diagnostic procedure. Detection rate was 100%. In those with high risk, 7 chorionic villi sampling and 38 amniocenteses were performed. False-positive rate was 5.1%. Conclusion. The results of the first-trimester screening in Croatia confirmed high sensitivity and better specificity of the combined ultrasonic and biochemical markers, in relation with the second-trimester biochemical screening test.
