Introduction Recent clinical data suggest that early administration of vasopressin analogues may be advantageous compared to a last resort therapy. However, it is still unknown whether vasopressin and terlipressin are equally effective for hemodynamic support in septic shock. The aim of the present prospective, randomized, controlled pilot trial study was, therefore, to compare the impact of continuous infusions of either vasopressin or terlipressin, when given as first-line therapy in septic shock patients, on open-label norepinephrine requirements.

Introduction Previous findings suggest that a delayed administration of phenylephrine replacing norepinephrine in septic shock patients causes a more pronounced hepatosplanchnic vasoconstriction as compared with norepinephrine. Nevertheless, a direct comparison between the two study drugs has not yet been performed. The aim of the present study was, therefore, to investigate the effects of a firstline therapy with either phenylephrine or norepinephrine on systemic and regional hemodynamics in patients with septic shock.

This study confirms the importance of monitoring a combination of several biomarkers in order to obtain a reliable diagnosis. Maximal presepsin levels could alert clinicians not to suspend antibiotic treatments and to carefully monitor septic patients' state of health, even after clinical symptoms have disappeared and PCT levels returned to normal.
