Neonatal necrotizing enterocolitis: implications for an infectious disease.

R M Kliegman

    Pediatric Clinics of North America
    |May 1, 1979
    PubMed
    Summary

    Necrotizing enterocolitis (NEC) is a complex syndrome, not a single disease, often involving formula feeding, ischemia, and bacterial growth. Therapeutic approaches for NEC should always consider it an infectious disease.

    Area of Science:

    • Neonatal Medicine
    • Gastroenterology
    • Infectious Disease

    Background:

    • Necrotizing enterocolitis (NEC) presents with a wide spectrum of severity and clinical manifestations.
    • NEC may represent a syndrome with diverse etiologies rather than a distinct disease entity.

    Purpose of the Study:

    • To elucidate the multifactorial pathogenesis of necrotizing enterocolitis.
    • To emphasize the central role of bacterial involvement in NEC development and management.

    Main Methods:

    • Review of proposed etiological factors in necrotizing enterocolitis.
    • Analysis of the role of bacterial agents in NEC pathogenesis, including pneumatosis and intestinal injury.

    Main Results:

    • Formula feeding, intestinal ischemia, and bacterial proliferation are key components in NEC pathogenesis.
    • Bacteria are crucial for pneumatosis and can exacerbate ischemic intestinal injury.
    • Infectious gastroenteritis can cause NEC in low-risk infants; in stressed newborns, bacteria can initiate NEC following mucosal injury.

    Conclusions:

    • Necrotizing enterocolitis is a syndrome with varied causes, where bacteria play a pivotal role.
    • Regardless of whether bacteria are primary or secondary factors, NEC must be managed as an infectious condition.
