AbstractTherapy with colony-stimulating factors has been extended beyond their use in accelerating myeloid cell recovery to take advantage of their immune function-enhancing properties. Studies in animal models and with human subjects suggest a potential role as adjunctive therapy in infections of non-neutropenic hosts, including those with sepsis. Granulocyte colony-stimulating factor may play a pivotal role in the induction of lipopolysaccharide desensitization by nontoxic lipid A analogues proposed for the prevention of sepsis; granulocyte macrophage colony-stimulating factor may be useful in reversing the immune paralysis described in later stages of sepsis. Significant issues of exogenous colony-stimulating factor therapy must be addressed, however: the optimal timing, dose, and clinical context (e.g., type of immunosuppression, duration of infection-inciting stimulus) as well as tissue-specificity of the activities and net effect of potentially conflicting responses (e.g., immune restorative and procoagulant effects of granulocyte macrophage colony-stimulating factor). Resolution of these issues will require carefully designed clinical studies with meticulous monitoring of immunologic parameters.
