Increased serum interleukin-8: correlation with poor prognosis in patients with postoperative multiple organ failure
1First Department of Surgery, Yamaguchi University, School of Medicine, Japan.
Abstract:
This study investigated whether cytokines and colony-stimulating factors can predict prognosis in patients with postoperative multiple organ failure (MOF). We evaluated 14 patients with postoperative MOF who underwent operation for cardiovascular disease. Seven patients recovered from MOF (survivors) and seven did not recover and died (nonsurvivors). The white blood cell (WBC) count, granulocyte colony-stimulating factor, monocytic colony-stimulating factor, interleukin-6 (IL-6), and IL-8 were measured on the day the patients were judged to be in MOF and each week thereafter until the patients recovered or died. Survivors and nonsurvivors were equivalent in terms of age, gender, proportion of use of extracorporeal circulation, operation time, volume of blood transfusion, time from operation to the onset of MOF, the MOF score, proportion of bacteremia, duration of MOF, and number of failed organs. The mean duration of MOF was less than 2 weeks in both groups; therefore the measurements were compared on the first day of MOF and 1 week later. No significant differences between the two groups in terms of WBC counts, colony-stimulating factors, and IL-6 levels were noted. However, the serum level of IL-8 was significantly higher in nonsurvivors than in survivors. Patients with a high serum levels of IL-8 at the time of MOF had a poor prognosis.
Insights
Interleukin-8 (IL-8) levels can predict prognosis in patients with multiple organ failure (MOF) after cardiovascular surgery. Higher IL-8 serum levels indicate a poorer prognosis for MOF patients.
Area of Science:
- Biochemistry
- Immunology
- Critical Care Medicine
Background:
- Postoperative multiple organ failure (MOF) is a critical complication following cardiovascular surgery.
- Identifying reliable prognostic markers for MOF is crucial for patient management.
- Cytokines and colony-stimulating factors are key immune mediators potentially involved in MOF.
Purpose of the Study:
- To investigate the prognostic value of cytokines and colony-stimulating factors in patients with postoperative MOF.
- To determine if specific biomarkers can differentiate between survivors and nonsurvivors of MOF.
Main Methods:
- Evaluated 14 patients with postoperative MOF after cardiovascular surgery.
- Measured white blood cell (WBC) count, granulocyte colony-stimulating factor, monocytic colony-stimulating factor, interleukin-6 (IL-6), and interleukin-8 (IL-8) levels.
- Compared biomarker levels between survivors (n=7) and nonsurvivors (n=7) on the day of MOF onset and one week later.
Main Results:
- No significant differences were observed in WBC counts, colony-stimulating factors, or IL-6 levels between survivors and nonsurvivors.
- Serum levels of IL-8 were significantly higher in nonsurvivors compared to survivors.
- Elevated IL-8 levels at the time of MOF onset were associated with a poor prognosis.
Conclusions:
- Serum interleukin-8 (IL-8) is a potential prognostic biomarker for patients experiencing postoperative multiple organ failure (MOF).
- Higher IL-8 levels may indicate a higher risk of mortality in MOF patients.
- Further research is warranted to explore the therapeutic implications of IL-8 modulation in MOF.
