Milk fat globule epidermal growth factor-factor 8 mitigates inflammation and tissue injury after hemorrhagic shock in experimental animals.
Insufficient clearance of apoptotic cells leads to increased inflammation and exaggerated organ injury. The opsonizing protein, milk fat globule epidermal growth factor-factor 8 (MFG-E8), upregulates apoptotic cell clearance. The purpose of this study was to determine the degree of apoptotic cell clearance, and whether inflammation, organ injury, and survival are improved after treatment with recombinant human MFG-E8 (rhMFG-E8) after hemorrhagic shock. ⋯ The administration of rhMFG-E8 is a potent treatment in animals after hemorrhagic shock.

Acute trauma coagulopathy in seriously injured casualties may be initiated by tissue hypoperfusion. A targeted (or novel hybrid [NH]) resuscitation strategy was developed to overcome poor tissue oxygen delivery associated with prolonged hypotension. ⋯ Targeted resuscitation (NH) attenuates the development of acute trauma coagulopathy and systemic inflammation with improved tissue perfusion and reduced metabolic acidosis in a model of complex injury. This emphasizes the challenge of choosing a resuscitation strategy for trauma patients where the needs of tissue perfusion must be balanced against the risk of rebleeding during resuscitation.
