This editorial comment discusses the effects of erythropoietin in preclinical models of septic shock endotoxemia hemorrhagic shock spinal cord trauma and zymosan-induced multiple organ failure. Erythropoietin EPO is a 34 kDa glycoprotein hormone that controls the proliferation differentiation and survival of erythroid progenitor cells through an antiapoptotic mechanism. It has become apparent that EPO protects many organs including brain heart kidney and liver against the injury caused by ischaemia reperfusion hemorrhagic shock and systemic inflammation. In this issue of Critical Care Kao and colleagues 1 report their findings in an established murine model of polymicrobial sepsis. They found that recombinant human EPO 400 IU kg exerts significant beneficial effects when it is given as late as 18 hours after caecal ligation and puncture CLP . Although EPO had no effect on the small decline in blood pressure the decline in platelet and white blood cell counts or the rise in lactate it significantly increased tissue perfusion and reduced tissue hypoxia. Within 18 hours after CLP there was a decline in the number of perfused capillary beds reduced oxygen .
