E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Post-operative immunological stimulation in severe immune suppression. The study population is made up of adult, which are able to give their inform consent by their own.

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
A postoperative vaccination with influenza-vaccine or postoperative treatment with sargramostim within the phase of severe immunsuppression, leads to (compared to placebo) an improvement of immunoreactivity by absence of an immuno paralysis (measured by the normalisation of the HLA-DR expression of monocytes, > 10.000 antigens/monocyte). |
|
E.2.2 | Secondary objectives of the trial |
- postoperative infection rate
- incidence of postoperative delirium (CAM-ICU, NuDESC, DDS)
- postoperative ventilation time (hours), ICU length of stay, Charité length of stay, APACHE-II-Score, SAPS-II-Score, SOFA-Score, TISS-28-Score
- The first 33 included patients will be analysed in regard to the following parameters:
1. Parameters of immune system function
- levels of different cytokines
- Th1/Th2 ratio,
- Th17/Treg ratio,
2. quantitative expression of transcription factors (T-bet, Eomesodermin, GATA-3, Foxp3, RORγt, PU.1) and proteins (SOCS-3, SOCS-1, TGF-ß, IL-17) as well as the synthesis of associated effector proteins
