Immunoreactive urinary prostaglandins A and E in neonates, children, and adults.
Urinary prostaglandins were measured by radioimmunoassay in neonates (31-35 weeks gestational age), children (4-15 years) and adults (24-36 years). Neonates showed significantly lower levels of both iPGE and iPGA compared to children (p less than 0.01) and adults (p less than 0.01). Children also had significantly lower levels than adults (p less than 0.01). Since urinary prostaglandins reflect intrarenal levels of prostaglandins, the results support other studies that suggest prostaglandins may play a role in controlling renal blood flow in infants.
