Abstract
OBJECTIVE
To determine whether the serum concentrations of some circulating cytokines (as highly sensitive markers of inflammation) are of value in predicting the outcome of patients with cardiogenic shock and end-stage heart disease, who undergo ventricular assist device implantation until heart transplantation.
DESIGN
Cohort study.
SETTING
University teaching hospitals.
PATIENTS
Twenty patients with cardiogenic shock or end-stage heart disease were consecutively selected for this study, if assist device implantation was performed as a bridge to heart transplantation.
MEASUREMENTS AND MAIN RESULTS
The circulating concentrations of the cytokines interleukin (IL)-1 beta, IL-6, IL-8 and tumor necrosis factor (TNF)-alpha were monitored from the beginning to the end of assist device support two to three times a week, using commercial enzyme-linked immunosorbent assays (ELISA). In all patients, circulating IL-6 and IL-8 values were increased shortly after assist device implantation. In patients with uncomplicated courses, IL-6 and IL-8 concentrations decreased after an initial increase and were low at the time of transplantation, whereas serum cytokine concentrations increased and remained increased in the nonsurvivors (survivors vs. nonsurvivors, p < .001). Circulating IL-1 beta and TNF-alpha concentrations were rarely detectable.
CONCLUSIONS
Monitoring of IL-6 and IL-8 values during ventricular assist device support provides a means of early identification of high-risk patients that may allow optimization of antimicrobial therapy and selection of the appropriate time for transplantation.
