Genetic factors and risk of persistent pulmonary hypertension in newborns

Official title: Prostaglandin G/H Synthase-1 (PTGS1) Genetic Variation and Increased Risk for Persistent Pulmonary Hypertension of the Newborn (PPHN)

Run by Medical College of Wisconsin · NCT00710177 · Data updated 2026-11-12

This study is trying to see if certain genetic changes in newborns are linked to a higher risk of persistent pulmonary hypertension when their mothers used pain relievers during pregnancy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are infants born at or after 34 weeks gestational age, either diagnosed with PPHN or healthy controls.

Probably not a fit

Patients with lethal congenital anomalies or significant structural congenital heart or gastrointestinal tract abnormalities may not benefit from this study.

What this trial studies

This observational study aims to investigate the association between genetic variations in the PTGS1 gene and the risk of persistent pulmonary hypertension of the newborn (PPHN) related to in utero exposure to non-steroidal anti-inflammatory drugs (NSAIDs). The study will compare the incidence of PTGS1 genetic variants in infants diagnosed with PPHN to healthy control infants. By analyzing the genetic sequences, the researchers hope to identify specific variations that may increase susceptibility to ductal constriction and PPHN. This research could provide insights into the biological mechanisms underlying PPHN and its association with NSAID exposure during pregnancy.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and prevention strategies for PPHN in newborns.

How similar studies have gone: Other studies have suggested associations between genetic variations and susceptibility to conditions like PPHN, but this specific genetic focus on PTGS1 in relation to NSAID exposure is relatively novel.
