Septic Shock

Human albumin, Sepsis
Brief summary
Albumin is a key regulator of fluid distribution within the extracellular space and possesses several properties beyond its oncotic activity, including binding and transport of several endogenous molecules, anti-inflammatory and anti-oxidant actions, nitric oxide modulation, and buffer function. The accumulating evidence suggests that supplementation of albumin may provide survival advantages only when the insult is severe as in patients with septic shock. Prospective randomized trials on the possible impact of albumin replacement in these patients with septic shock are lacking. The aim of the study is to investigate whether the replacement with albumin and the maintenance of its serum levels at least at 30 g/l for 28 days improve survival in patients with septic shock compared to resuscitation and volume maintenance without albumin. In this prospective, multicenter, randomised trial, adult patients (≥18 years) with septic shock will be randomly assigned within a maximum of 24 hours after the onset of septic shock after obtaining informed consents to treatment or control groups. Patients assigned to the treatment group will receive a 60 g loading dose of human albumin 20% over 2-3 hours. Serum albumin levels will be maintained at least at 30 g/l in the ICU for a maximum of 28 days following randomization using 40-80 g human albumin 20% infusion. The control group will be treated according to the usual practice with crystalloids as the first choice for the resuscitation and maintenance phase of septic shock. The primary end point is 90 days mortality and secondary end points include 28-day, 60-day, ICU, and in-hospital mortality, organ dysfunction/failure, and length of ICU and hospital stay. In total 1412 patients need to be analyzed, 706 per group. Assuming a dropout rate of 15%, a total of 1662 patients need to be allocated.
Detailed description
This is a prospective, multicentre, randomised, controlled, parallel-grouped, open-label, interventional clinical trial in which 1662 patients are planned to be allocated. Subjects will be randomized in a 1:1 ratio to receive either Albumin or routine treatment with crystalloids. Treatment will be continued at maximum for 28 days or until the patient leaves the ICU. Primary endpoint measurement will be carried out 90 days after randomisation
Interventions
The initial dose of the trial drug must be started within 6 to 24 hours after the beginning of the septic shock. Starting dose: 60 g human albumin 20% (Albutein® 200 g/L, infusion solution) over 2-3 h Daily administration of the trial drug will be based on the serum albumin concentration measured each day. Dose adjustment will follow a predetermined schedule with the aim of maintaining a serum albumin concentration of at least 30 g/l. Administration of the trial drug will continue for a maximum of 28 study days after randomisation and only as long as the participant is being treated in the ICU.
