Meta-and ortho-Tyrosine are known markers of oxidative stress, while the physiological isomer, para-Tyrosine is suggested the antagonize the effects of meta- and ortho-Tyrosine. The changes in the serum levels of meta- and ortho-Tyrosine have been found to be paralel to that of the common sepsis markers. The hypothesis of the study is, that supplementation of para-Tyrosine (p-Tyr) in the early phase of sepsis may diminish some specific inflammatory procedures and thus may have a favourable impact on the disease progress, and consequently on the mortality.

PHASE2
Data suggest, that among the amino acids, the meta- and ortho- isomers of tyrosine are potential markers of oxydative stress. The changes in their serum levels (and urinary excretion) in sepsis were found to be parallel to the changes of the common inflammatory markers, i.e. C-reactive protein (CRP) and pro-calcitonin (PCT). However, para-Tyrosine, which is the isomer physiologically present, seemed to have different kinetics. Furthermore, according to the observations, pathological processes linked to the inflammation could be attenuated or partially or completely reversed by para-tyrosine. The hypothesis of the study is, that supplementation of para-Tyrosine (p-Tyr) in the early phase of sepsis may diminish some specific inflammatory procedures and thus may have a favourable impact on the disease progress, and consequently on the mortality. The primary objective of the study is to evaluate, whether oral P-Tyr supplementation reduces mortality compared to placebo group during the ICU stay in patients with sepsis. The primary endpoint is the comparison of mortality starting from randomization and start of treatment (which should be on the same day) during the period of ICU stay between the active treatment group and placebo group. The secondary objectives of the study are: to evaluate whether supplementation of p-Tyr has effect on clinical outcome of sepsis compared to placebo in patients receiving appropriate standard care; to evaluate the effect of p-Tyr supplementation on 28-day survival of patients with sepsis; to evaluate, whether the treatment can reduce the time of the ICU stay, to evaluate the effect on overall mortality of patients with sepsis during their hospitalization, to evaluate the effect of p-Tyr supplemetation on the overall hospitalization time, to evaluate the safety of the investigational product. The investigators wish to explore To explore whether serum level of p-Tyr can be maintained with the oral supplementation; dynamics and interrelation of the levels of oxidative stress markers (o- and m-Tyr) and the physiologic isomer of Tyr (p-Tyr) and Phenylalanine (Phe) and the correlation of o-Tyr and m-Tyr serum levels and other parameters of inflammation.
