Placental inflammation, particularly chorioamnionitis, is linked to necrotizing enterocolitis (NEC) severity in premature infants. Early detection of intrauterine inflammation can improve outcomes for infants at risk of NEC.
Area of Science:
- Neonatalogy
- Perinatology
- Gastroenterology
Background:
- Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in premature infants.
- Risk factors include preterm birth, intrauterine inflammation, and hypoxia.
- Chorioamnionitis is a significant factor linked to intestinal injury.
Purpose of the Study:
- To review the clinical impact of the intrauterine environment on intestinal injury.
- To explore the link between placental pathology and NEC development.
- To identify infants at risk for NEC and inform treatment strategies.
Main Methods:
- Literature search of PubMed, EMBASE, and Scopus databases.
- Inclusion of own clinical and laboratory research.
- Emphasis on prospective multicenter studies with detailed predictors.
Main Results:
- Placental inflammatory and vascular lesions correlate with NEC severity.
- Higher-grade chorioamnionitis with fetal response increases surgical NEC risk.
- Routine placental pathology use in clinical decisions is recommended.
Conclusions:
- Understanding in utero inflammation is crucial for NEC prediction.
- Identifying at-risk infants early can lead to timely interventions.
- Novel immunomodulatory treatments may improve outcomes for vulnerable infants.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
