Bleeding disorder from the "fat overload" syndrome.

A N Campbell, M H Freedman, P B Pencharz

    JPEN. Journal of Parenteral and Enteral Nutrition
    |July 1, 1984
    PubMed
    Summary

    Fat overload syndrome in a child receiving parenteral nutrition caused a bleeding disorder due to abnormal platelet function. The condition resolved when lipid levels normalized, highlighting the impact of Intralipid on platelet activity.

    Area of Science:

    • Pediatric Medicine
    • Hematology
    • Nutrition Science

    Background:

    • Total parenteral nutrition (TPN) is a critical intervention for patients unable to receive enteral nutrition.
    • Intralipid, a common lipid emulsion in TPN, provides essential fatty acids and calories.
    • Fat overload syndrome (FOS) is a rare but serious complication of lipid-intensive therapies.

    Observation:

    • A 7-year-old girl on TPN with 20% Intralipid developed FOS.
    • The patient presented with a significant bleeding disorder, specifically severe hematemesis.
    • Electron microscopy revealed lipid phagocytosis within platelets.

    Findings:

    • The bleeding disorder was attributed to impaired platelet function.
    • Abnormal platelet function correlated with the presence of lipid within the platelets.
    • Resolution of lipemia led to the reversal of platelet dysfunction and bleeding.

    Implications:

    • This case highlights a potential mechanism of platelet dysfunction in FOS.
    • Careful monitoring of lipid levels is crucial in patients receiving TPN with Intralipid.
    • Understanding lipid-platelet interactions is important for managing TPN-related complications.
