Zusammenfassung
Gemäß den grundlegenden Ausführungen zur Definition der Sepsis in Kap. 1 steht die systemische Einschwemmung von Mikroben (in der Regel Bakterien oder Pilze) und/oder mikrobiellen Produkten am Anfang der pathophysiologischen Abläufe der Sepsis (Abb. 9-1). Unter den bakteriellen Toxinen haben die Endotoxine gram-negativer Bakterien besondere Beachtung gefunden (Tabelle 9-1). Ihr pathogenetisches Prinzip ist die allen Endotoxinen gemeinsame Lipid-A-Struktur, durch deren beobachtungen am Menschen eine Vielzahl typischer Charakteristika einer Sepsis reproduzieren lassen. Zahlreiche Untersuchungen zur Wirkung des Lipid A haben jedoch gezeigt, daß die meisten (wenn nicht alle) Effekte dieses bakteriellen Agens nicht aus einer „direkt-zytotoxischen“ Wirkung resultieren, sondern mittels Aktivierung körpereigener Mediatorkaskaden und inflammatorisch kompetenter Zellen induziert werden [6, 41].
