Interleukin-1 and interleukin-1 antagonism in sepsis, systemic inflammatory response syndrome, and septic shock.
Interleukin-1 (IL-1) is one of several proinflammatory cytokines produced during infection, sepsis, and the systemic inflammatory response syndrome (SIRS) that serves to initiate the host inflammatory response and to integrate nonspecific immunity. Many of IL-1's biologic effects are beneficial to the host in times of stress, but when produced for extended periods of time or in excessive quantities, IL-1 contributes to morbidity and mortality. ⋯ This article will review the role for IL-1 in sepsis and septic shock, and the function and status of the IL-1 receptors and IL-1 receptor antagonist in modulating IL-1 actions. The results of investigations of IL-1 inhibition in animal models and in human subjects with sepsis and septic shock will also be reviewed.

Small-volume resuscitation with 7.2% NaCl/10% dextran 60 (HHS) restores cardiovascular stability faster than all other therapeutic modalities currently known. This study was undertaken to elucidate the effects of HHS on the brain, specifically on the formation of posttraumatic brain edema. HHS was administered to anesthetized albino rabbits with or without a focal cryogenic brain lesion and hemorrhagic shock. ⋯ We conclude that small-volume resuscitation with HHS does not worsen posttraumatic brain edema. To the contrary, our results show that it decreases cerebral water content even in regions close to the injury. This makes it worthwhile to investigate the benefits of HHS for the treatment of intracranial hypertension.
