“SERUM PLACENTAL GROWTH FACTOR LEVELS AND UTERINE ARTERY DOPPLER
PULSATILITY INDEX AT 11-13 WEEKS 6 DAYS GESTATION AS EARLY PREDICTIVE
MARKERS OF PRE-ECLAMPSIA AT TERTIARY CARE HOSPITAL: A PROSPECTIVE
OBSERVATIONAL STUDY”
Abstract
ABSTRACT OBJECTIVE: To detect serum
placental growth factor levels and uterine artery doppler pulsatility
index for predicting pre-eclampsia and assess their association with the
severity of pre-eclampsia. DESIGN: Prospective observational
study SETTING: Tertiary care centre POPULATION: All
antenatal women from 11 to 13+6weeks gestation attending antenatal
clinic during study period. METHODS: This involved 160
antenatal women, from 11-13+6 weeks gestation. Serum PlGF levels and UA
doppler mean P.I measured and patients were followed up upto delivery
and observed for the development of pre-eclampsia and its severity.
MAIN OUTCOME MEASURES: PIGF Value cut-off was 40.33pg/ml with
the sensitivity of 97.5 % and Specificity was 98.3%. For the PI Value
of 1.85 the sensitivity was found to be 74.4% and Specificity was found
to be 92.5%. RESULTS: Mean serum PlGF levels for pre-eclampsia
patients was 25.09pg/ml and for normotensive patients mean PlGF level
was 65.05pg/ml. Mean UA doppler P.I for pre-eclampsia patients was 2.02
and for normotensive patients was 1.39. Mean PI value increased with
increasing severity of preeclampsia. CONCLUSION: Early
recognition of women will help initiation of prophylactic measures and
enhanced surveillance. First trimester UA Doppler with serum PlGF
together with maternal characteristics can be used as a reliable
screening test for preeclampsia prediction and to reduce feto-maternal
morbidity KEYWORDS: uterine artery (UA) doppler pulsality index
