Screening study evaluates macrophage function and cytokine levels after major injury, indicating potential therapeutic strategies.

The study aims to evaluate monocyte and macrophage function in response to major injury and explore resulting immunosuppression.
Screening study of 58 patients with injury, assessing macrophage-related variables and monokine levels.
Monoclonal antibody phenotyping (Leu M3) and serial measurements of IL-1, PGE2, and interferon gamma were conducted on specific posttrauma days.
Analyzed monocyte function and cytokine output over a 21-day post-injury period.
Monocytosis observed with peak Leu M3-positive cells at 32% compared to 15% in controls.
Elevated macrophagic PGE2 output was up to eightfold higher on days 5 and 7 (0.441 ng/mL vs 0.052 ng/mL).
Significant suppression of macrophagic IL-1 and interferon gamma levels observed in the early post-injury period.

Eugen Faist (1988) studied this question.
