Actions and interactions of mediator systems and mediators in the pathogenesis of ARDS and multiorgan failure.
A great variety of mediators and mediator systems are involved in the disturbance of the microcirculation and vascular permeability following polytrauma and sepsis. The locally accentuated, organ related activation and the cooperation of several of these mediators and mediator systems over a longer period of time seem to be responsible for the development of an acute organ failure in terms of ARDS and MOF. Cytokines from macrophages seem to be the determining factors converting a primarily functional and reversible systemic vascular reaction into organ related morphological lesions. This pathogenetic complexity has to be considered in future concepts for therapy and prophylaxis with regard to the hierarchical rank of the mediators involved.
