Systems Analysis of Antigen Presenting Cells in Human Sepsis

ICU septic and non-septic patients will be subjected to repeated blood samples at the following time-points: ICU admission, day 4/5, ICU and hospital discharge, 3 months. Patients exhibiting ICU-acquired infection will also be sampled at the time of diagnosis (up to 6 additional blood samples of 20 mL within 3 months = 120mL)

Healthy controls (blood donors and patients undergoing elective cataract surgery) will be subjected to one single blood sample of 20 mL.
