Inflammation and all-cause mortality in patients undergoing peritoneal dialysis
DOI: 10.31744/einstein_journal/2024AO0627
Highlights
Higher plasma levels of CCL2 and lower plasma levels of TNF-α are associated with a greater risk of transfer to hemodialysis or mortality.
Lower levels of IL-17 in the dialysate are associated with a greater risk of transfer to hemodialysis or mortality.
These findings suggest that inflammatory biomarkers can be valuable tools for predicting all-cause mortality and transfer to hemodialysis in patients undergoing peritoneal dialysis.
ABSTRACT
Objective:
This study aimed to evaluate inflammatory biomarkers in patients undergoing peritoneal dialysis and investigate their association with all-cause mortality or transfer to hemodialysis.
Methods:
This prospective cohort study included 43 patients undergoing peritoneal dialysis. Plasma levels of cytokines were measured using flow cytometry and capture enzyme-linked immunosorbent assay. Biomarkers were categorized based on their respective median values. Survival analysis was conducted using the Kaplan-Meier estimator, considering two outcomes: all-cause mortality and transfer to hemodialysis.
Results:
After adjusting for confounding factors, plasma levels above the median of the levels of CCL2 and plasma, as well as below the median of TNF-α, and the median of dialysate IL-17 levels, were associated with an increased risk of experiencing the specified outcomes after approximately 16 months of follow-up.
Conclusion:
These findings suggest that inflammatory biomarkers may be a valuable tool for predicting allcause mortality and transfer to hemodialysis in patients undergoing peritoneal dialysis.
