Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are extremely preterm infants born between gestational ages 22+0 to 27+6 weeks.

Probably not a fit

Patients with severe complications detected within the first 72 hours of life or major congenital anomalies may not benefit from this study.

What this trial studies

This research aims to evaluate the effectiveness of probiotic supplementation in reducing the risk of necrotizing enterocolitis (NEC) and neonatal mortality among extremely preterm infants born before 28 weeks of gestation. The study involves a double-blinded, multicenter randomized controlled trial with 1620 participants across six neonatal units in Sweden and four in Denmark. Infants in the intervention group will receive a specific probiotic combination mixed with breastmilk, while the control group will receive breastmilk without probiotics. The primary outcome will assess the incidence of NEC and mortality, with secondary outcomes focusing on other neonatal morbidities.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of NEC and neonatal mortality in extremely preterm infants.

How similar studies have gone: Previous studies have shown reduced incidence of NEC in preterm infants, but this specific approach for extremely preterm infants is novel and underexplored.
