Study Details

Brief summary:

Neonatal respiratory distress syndrome affects babies who are born preterm and requires them to be placed on a ventilator in the Intensive Care Unit. Over 15 million babies were born premature and these numbers have been increasing. It is caused by lungs which are still too immature to produce adequate amounts of surfactant. This surfactant reduces the alveolar surface tension and maintains the alveoli from collapsing. Collapsed alveoli prevent gas exchange and greatly increase work of breathing. Surfactant is a biochemical complex made up mostly of phospholipids such as phosphatidylcholine and phosphatidylglycerol and these, in turn, appear to be synthesized by lysophosphatidylcholine acyltransferase 1 (LPCAT 1). The investigators have previously established that hLPCAT1 mRNA in maternal serum correlates with lamellar body count, a well established clinical marker of fetal lung maturity.

Interventions and Outcome Measures

Arms

Women Receiving Antenatal Steroids

Group 2: Determine how (and if) serum hLPCAT1 mRNA changes with administration of a course of steroids by measuring its plasma levels before, 24hrs after the first dose and 24hrs after the second dose of bethamethasone as well as one and two week after the first dose. This is accomplished through a simple blood draw. We seek to understand the effects of the 2nd dose of steroids and determine if, once the hLPCAT1 expression begins, does it continue or does it turn off again after some time from steroid administration.

Normal Pregnancy Controls

1) Group 1: Determine the plasma levels of hLPCAT1 mRNA in pregnant women from 32- 36+6/7 weeks gestation. This is accomplished through a simple blood draw. More specifically, we seek to find out, at what moment in gestation, expression spontaneously begins.

Interventions

blood draw

Blood draw (2.5mL) to assess mRNA LPCAT1 levels

Primary outcome measure

  • Change in LPCAT1 mRNA levels in maternal plasma after antenatal steroid administration [ Time Frame: The time points will be a baseline before steroids, 24h after the first dose, 24h after the second dose, a week after steroids and two weeks after steroids. ]
