[The pathogenesis of ischemic hepatitis]

Ischemic hepatitis is inflammation caused by necrosis of liver cells due to ischemia and hypoxia caused by low cardiac output or septic shock. It is often complicated by heart failure or severe septic shock. One of the pathogenesis of ischemic hepatitis is hepatocyte injury caused by ischemia and hypoxia, which results in damage-associated molecular patterns (DAMPs) release and binding to membrane receptors such as toll like receptors (TLRs) to cause inflammatory reactions.The other is when the ischemic liver is reperfused, hepatocyte mitochondrias will produce a large amount of ROS causing ischemia reperfusion injury. These two mechanisms and related molecular pathways are elaborated in this paper.
