简要总结
Septic shock is a major health problem. In the clinical practice guidelines of the Surviving Sepsis Campaign is recommended to add vasopressin (VP) or epinephrine in case of not reaching the goal of mean arterial pressure (MAP) although with a low level of evidence.
This is a clinical trial with the purpose of comparing the efficacy and safety of norepinephrine (NE) plus placebo versus NE plus terlipressin (TP) in adult patients with septic shock and with a Sepsis related Organ Failure Assessment score (SOFA)> 4 points. The primary objective will be a combined end-point: reduction of organic dysfunction measured at 72 h by SOFA score and by the increase in ICU (Intensive care unit) -free days measured at 28 days.
详细描述
Introduction
Septic shock is a major health problem. The clinical practice guidelines of the Surviving Sepsis Campaign establish the use of NE if after resuscitation with fluids a MAP> 65 mm Hg is not achieved. In these guidelines, it is recommended to add VP or epinephrine in case of not reaching the goal of MAP although with a low level of evidence.
TP is a synthetic analogue of VP with a long half-life. Preliminary studies on the use of TP associated with NE have not shown a decrease in mortality, although a reduction in organic dysfunction at 72 h, with discordant data regarding the rate of adverse events.
Material and Methods
Randomized, parallel, double-blind and multicenter clinical trial with the purpose of comparing the efficacy and safety of NE plus placebo versus NE plus TP in adult patients with septic shock and with a SOFA score> 4 points. The threshold dose of NE> 0.2 µg / kg / min is chosen to associate the second vasopressor (TP or placebo). The primary objective will be a combined end-point: reduction of organic dysfunction measured at 72 h by SOFA score and by the increase in ICU -free days measured at 28 days. The secondary objectives will be: mortality at 28 and 90 days, the need of renal replacement therapies, mechanical ventilation-free days, vasopressor-free days, and adverse reactions. Sample size of 152 patients (76 per arm), stratified by center and severity of illness. In addition, 6 single nucleotide polymorphisms of the vasopressin V1a receptor and a polymorphism of leucyl / cystinyl aminopeptidase or vasopressinase will be determined to establish its association with mortality in septic shock and with the efficacy and the occurrence of adverse effects due to the use of TP.

结局指标
主要结局
Days of life free of stay in the Intensive Care Unit
时间窗: 28 days
Number of the days of life free of stay in the Intensive Care Unit measured after the administration of terlipressin / placebo
Organ failure
时间窗: 72 hours
Number of organ failures related sepsis. Assessment Sepsis related Organ Failure Assessmen scale (SOFA scale) after administration of terlipressin / placebo. These scale assesses organ dysfunction. In patients with infection, a SOFA score ≥ 2 points (in patients with chronic organ dysfunction, a 2 point increase from baseline score) is diagnostic of sepsis.
