Many critically ill patients with stabilized hemo-dynamics die with signs of multiorgan failure. One of the reasons is the derangement of microcircu lation and tissue perfusion. It has been shown that microcirculatory distress left uncorrected for 24 hours is single independent predictor of mortality in sepsis. Setum lactate is the only indicator of microcirculatory changes that is monitored routinely in all critically ill patients. It has been widely believed that hyperlactatemia in sepsis is marker of tissue hypoxia and indicates the existence of oxygen debt re iulting from tisiue hypoperfusion and anaerobic glycolysis. Attempts to correct hyperlactatemia by delivering supranormal oxygen amounts have failed in septic patients. The term "shock" lactate refers to hyperlactatemia originating from oxygen debt. Human studies failed to demonitrate the relationship between hyperlactatemia and tissue hypo-perfusion in the late phase of sepsis. Adrenergic stimulation in sepsis and accelerated aerobic glycolysis have been proposed as a likely mechanism of hyperlactatemia. Both exogenous and endogenous catecholamines are correlated with septic hyperlactatemia. Aerobically generated lactate me diated by cytokines is called "stress" lartate and may serve as a marker of hypermetabolism rather than tissue hyperperfusion. Many studies and guidelines recommend targeting resuscitation to normalize lactate in septic patients. These recommendations need to be taken with reierve. Since lartate serves, under stress, as a source of energy and can be used as a fuel for oxidation as well as for glucose production, attempts to normalize lactate might be even harmiul. Although high lactate clearance, due to a correction of oxygen debt contributes to a better prognosis in sepsis, the unusual complexity of lactate makes it almost impossible to make an unambiguous therapeutic decision, when comes to a lactate-guided treatment in sepsis.

Despite the great progress that has been made in recent decades in the intensive treatment of critically ill patients with intra abdominal infections, antibiotic therapy and modern surgical techniques, secondary peritonitis is still accompanied by significant morbidity and mortality. The response to infection can be variable between different individuals. Scientific evidence support hypothesis that this inter-patient variability can be at least partially explained by genetic influence which may have an important role in the development of sepsis, as well as in severity of complications and death. An infection triggers complex immune response of the host and affects the balance between coagulation and fibrinolysis. This imbalance can lead to hypercoagulability but also to the microcirculation disturbance which can lead to multiple organ dysfunction syndrome (MODS) and septic shock. Common polymorphisms of genes which encode proteins with important role in coagulation and fibrinolysis could be of great importance in susceptibility for sepsis, possible complications and clinical outcome. Early genetic information may become very useful for identification of patients with high risk of developing severe sepsis and multiple organ dysfunctions, in order to design better, more personalized therapy with less severe adverse effects.
