Immunoglobulin changes after varied resuscitation regimens

D F Faillace, A M Ledgerwood, C E Lucas

    The Journal of Trauma
    |January 1, 1982
    PubMed
    Summary

    Albumin supplementation in hypovolemic shock resuscitation increases serum albumin but lowers immunoglobulins (IgG, IgM, IgA). Steroid therapy did not alter immunoglobulin levels compared to controls, suggesting albumin impacts the immune response to shock.

    Area of Science:

    • Immunology
    • Trauma Medicine
    • Biochemistry

    Background:

    • Hypovolemic shock resuscitation often involves fluid and protein administration.
    • Previous studies noted albumin supplementation affects serum protein levels but did not assess immunoglobulins.
    • The impact of resuscitation strategies on the immunoglobulin profile in severely injured patients remains unclear.

    Purpose of the Study:

    • To investigate the effects of albumin and steroid supplementation on immunoglobulin levels (IgG, IgM, IgA, IgD) in severely injured patients with hypovolemic shock.
    • To compare immunoglobulin levels in supplemented patients versus control patients.
    • To determine if albumin supplementation alters the normal immunoglobulin response to shock.

    Main Methods:

    • Measurement of immunoglobulins (IgG, IgM, IgA, IgD) in frozen sera from 184 severely injured patients.

  • Patients were prospectively randomized into three groups: control, supplemental albumin therapy, and supplemental steroid therapy.
  • Analysis of correlations between immunoglobulin levels, shock severity, and resuscitation volume.

    • Main Results:

    • Control patients showed significant reductions in IgG, IgM, and IgA, correlating with decreased total serum proteins and albumin.
    • Albumin supplementation increased serum albumin but caused a reciprocal decrease in serum globulins and immunoglobulins (IgG, IgM, IgA).
    • Steroid-supplemented patients had low serum proteins and immunoglobulins, similar to controls, with no significant correlation to shock or resuscitation parameters.

    Conclusions:

    • Albumin supplementation significantly alters the expected immunoglobulin response following hypovolemic shock.
    • The observed changes in immunoglobulins with albumin therapy warrant further investigation in the post-injury recovery period.
    • Steroid therapy did not appear to modify the serum protein or immunoglobulin profile in this cohort.
