Intestinal ischemia, frequently found in clinical states such as aortic bypass operations or hemorrhagic shock, is associated with loss of gut barrier function. Subsequent translocation of indigenous bacteria and endotoxin have been implicated as a major contributor to a systemic immuno-inflammatory response, which finally leads to multiple organ failure. There is increasing evidence that intestinal injury can result in the gut becoming a cytokine generating organ. This study was designed to show direct evidence of the gut as a major source of proinflammatory cytokines after intestinal ischemia and to further relate this cytokine response to the extent of intestinal ischemia/reperfusion. Additionally the potential role of the altered intestinal barrier function after intestinal ischemia for this cytokine response was investigated. ⋯ The gut becomes a cytokine liberating organ alter intestinal ischemia/reperfusion. This cytokine response is affected by certain conditions, but is not directly related to an impaired intestinal barrier function.
