Primaire uitkomstmaten
Change in transendothelial electrical resistance (TER) which will be measured using an Electric Cell-substrate Impedance Sensing device(ECIS)
Achtergrond van het onderzoek
Rationale:
Sepsis is characterized by the presence of inflammatory-induced endothelial integrity loss. This reduction in endothelial barrier function results in fluid leakage associated with organ failure. Currently, there is no therapy for loss of endothelial barrier function. Evidence is increasing that plasma has protective and restorative effects on endothelial barrier integrity and function in critically ill patients.
Objective:
To investigate whether plasma restores sepsis-induced endothelial barrier integrity in an in vitro model. This will be assessed by incubating human microvascular endothelial cells with plasma samples from septic shock patients.
Study design:
Single center observational study.
Intervention (if applicable):
None
Study population:
Patients with septic shock who are admitted to the ICU
Main study parameters/endpoints:
Changes in transendothelial electrical resistance (TER) and permeability of endothelial cells in vitro.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
The risks are negligible in this study. Blood samples will be obtained from the arterial line at quantities that are not harmful. Standard clinical care will not be altered. Participation in this study does not confer a potential benefit, but future patients with sepsis may benefit from results of this study.
Doel van het onderzoek
Plasma restores sepsis-induced endothelial permeabiliy as measured by transendothelial electrical resistance in an in-vitro ECIS model.
Onderzoeksopzet
Patient plasma will be retrieved at 2 time points. The first assesment is within 12 hours after arriving in the ICU.
