[Adrenal cortex function at different stages of burns]

G S Kolesnikova, M R Mordkovich

    Problemy Endokrinologii
    |March 1, 1981
    PubMed
    Summary

    Severe burn patients show altered blood corticosteroid levels, with initial increases during burn shock followed by decreases in later stages. This disrupts the normal 24-hour hormone release pattern.

    Area of Science:

    • Endocrinology
    • Trauma Medicine
    • Biochemistry

    Background:

    • Severe burns trigger significant physiological stress responses.
    • Hormonal regulation, particularly corticosteroids, plays a critical role in managing stress.
    • Understanding corticosteroid dynamics in burn patients is crucial for prognosis and treatment.

    Purpose of the Study:

    • To investigate the changes in blood corticosteroid levels in patients with severe burns.
    • To correlate corticosteroid concentrations with different clinical phases of burn disease.
    • To compare the circadian rhythm of corticosteroid release in burn patients versus healthy individuals.

    Main Methods:

    • Blood samples were collected from severe burn patients at various disease stages.
    • Corticosteroid levels were measured using established biochemical assays.
    • Data were analyzed to determine mean concentrations and compare circadian patterns.

    Main Results:

    • Mean daily blood corticosteroid levels were elevated in burn patients.
    • The highest corticosteroid concentration (112.6 +/- 21.7 micrograms %) was observed during the burn shock phase.
    • Levels decreased during acute burn toxemia (41.7 +/- 7.1 micrograms %) and initial septicotoxemia (49.4 +/- 5.4 micrograms %), and further dropped in burn exhaustion.
    • Circadian rhythm of corticosteroid release was significantly disrupted in burn patients.

    Conclusions:

    • Blood corticosteroid levels fluctuate significantly throughout the course of severe burn illness.
    • The pattern of corticosteroid changes suggests a complex endocrine response to burn trauma.
    • Disruption of the normal circadian corticosteroid rhythm is a key finding in severe burn patients.
