Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with end-stage renal disease undergoing hemodialysis (HD) are burdened with extremely high mortality rates (15% per year) and during the early stage (≤120days) the mortality rate is even higher (27% per year). Cardiovascular complications and bloodstream infections (BSIs) account for the vast majority of deaths in HD patients. In Denmark, BSIs occur in 14% of HD patients per year and is most frequently caused by Staphylococcus aureus (44%). The most frequent infectious complication is endocarditis that has fatal outcomes in ≈50% of the cases. Overall, 10% of HD patients die within 30 days after a positive blood culture for S. aureus. This project aims to answer key questions regarding HD patients' decreased ability to fight S. aureus BSIs and in particular the potential exacerbating effect of HD. We hypothesize that HD patients' blood is significantly compromised by the process of HD, to an extend that lowers immunoactivity against S. aureus. Moreover, we hypothesize, that contact activation promotes the coagulability of blood thus promoting biofilm formation by S. aureus which increases the overall risk of BSI. We will test these hypotheses by collecting blood and analyzing the inflammation and coagulation status in plasma samples from participants before and after HD. We will compare the level of the inflammatory markers in plasma from participants undergoing HD (n=180) to the level in plasma samples from three control groups: healthy volunteers (n=120), participants with renal disease not in dialysis (n=60) and participants undergoing peritoneal dialysis (n=40).
