Effects of cortisone on decrease of serum albumin secondary to experimental infections

M Deysine, N Leiblich, R Rubenstein

    Surgery, Gynecology & Obstetrics
    |October 1, 1980
    PubMed
    Summary

    Severe bacterial infections lower serum albumin. Administering methylprednisolone sodium succinate after infection onset in rodents mitigated this decrease, unlike pre-infection administration, suggesting a therapeutic window for steroid intervention.

    Area of Science:

    • Biomedical Science
    • Pharmacology
    • Veterinary Medicine

    Background:

    • Severe bacterial infections are clinically associated with reduced serum albumin levels.
    • Serum albumin plays a crucial role in maintaining oncotic pressure and transporting substances.
    • Understanding factors influencing albumin levels during infection is vital for patient management.

    Purpose of the Study:

    • To investigate the effect of methylprednisolone sodium succinate on serum albumin levels during bacterial infections.
    • To determine the optimal timing for steroid administration to mitigate infection-induced hypoalbuminemia.
    • To explore the potential mechanism of steroid action on albumin synthesis.

    Main Methods:

    • Experiments were conducted using canine and rodent models of severe bacterial infection.

  • Methylprednisolone sodium succinate was administered at different time points relative to infection onset.
  • Serum albumin levels were monitored throughout the experimental period.

    • Main Results:

    • Bacterial infections in both dogs and rats led to a significant decrease in total serum albumin.
    • In rodents, methylprednisolone sodium succinate administration *after* infection onset significantly reduced the decline in serum albumin.
    • Pre-infection administration of the steroid did not provide a protective or corrective effect on albumin levels.

    Conclusions:

    • The timing of methylprednisolone sodium succinate administration is critical for its effect on serum albumin levels during bacterial infections.
    • Post-infection treatment with this corticosteroid may help preserve serum albumin levels, potentially by stimulating hepatic albumin synthesis.
    • Further research into the mechanism of action, possibly involving the liver parenchyma, is warranted.
