Circulating fibronectin in burned patients.

J Grzybowski, M Dobke, A Rysinska

    Burns, Including Thermal Injury
    |July 1, 1983
    PubMed
    Summary

    Burn injury causes a significant drop in fibronectin levels, especially within the first 72 hours and during the second week post-injury. This decrease is more pronounced than overall protein changes, impacting the fibronectin/protein ratio.

    Area of Science:

    • Biochemistry
    • Immunology
    • Trauma Medicine

    Background:

    • Investigating biomarkers for burn injury is crucial for patient management.
    • Fibronectin, a key protein in wound healing and immune response, is a potential indicator of trauma severity.

    Observation:

    • Serial measurements of plasma and serum fibronectin were conducted in 24 non-septic burn patients.
    • Assays used included passive haemagglutination and electroimmunoassay for precise quantification.

    Findings:

    • A consistent pattern of decreased circulating fibronectin was observed in the initial 72 hours post-burn.
    • Fibronectin levels remained low during the postoperative period, particularly in the first and second weeks following injury.
    • The reduction in fibronectin was more significant than changes in total serum protein, altering the fibronectin/protein ratio.

    Implications:

    • Decreased fibronectin may indicate impaired wound healing or immune function in burn patients.
    • Monitoring fibronectin levels could aid in assessing burn severity and recovery progress.
    • Further research into fibronectin's role in burn pathophysiology is warranted.
