Main study outcome is the assessment of immune cell function after BCG vaccination and after surgery
Achtergrond van het onderzoek
Despite strictly implemented perioperative infection-preventive strategies, postoperative infection rates are still high (up to 20%). Surgery- and anesthesia induced immunosuppression contributes to such infections, which are associated with high mortality rates. In this project, this perioperative-induced immunosuppression will be investigated by a unique approach: We aim to improve patient’s host defence mechanisms by vaccination with Bacillus Calmette–Guérin (BCG), in order to facilitate a more efficient elimination of pathogens during the perioperative period. The inflammatory response after elective laparotomic surgery in BCG-vaccinated patients will be compared with placebo–vaccinated patients in a double-blind randomized trial.
Doel van het onderzoek
We hypothesize that induction of trained immunity through BCG vaccination may improve host defence mechanisms of patients throughout the perioperative period.
