Serum triglycerides and risk for death in Stage 3 and Stage 4 chronic kidney disease

Show Summary Details



An elevated triglyceride level is associated with cardiovascular and all-cause mortality in the general population. The associations between serum triglyceride and all-cause mortality among patients with chronic kidney disease (CKD) are unclear.


Patients with Stage 3 and Stage 4 CKD (estimated glomerular filtration rate 15–59 mL/min/1.73 m2) who had serum triglycerides measured prior to being classified as CKD were included. We examined the associations of serum triglyceride levels with all-cause mortality among 25 641 Stage 3 and Stage 4 CKD patients using Cox proportional hazard models and Kaplan–Meier survival curves.


In the Cox model, after adjusting for relevant covariates including other lipid parameters, serum triglyceride level 150–199 mg/dL was not associated with death [hazard ratio (HR) 1.00, 95% confidence interval (95% CI) 0.92–1.10] relative to serum triglyceride <150 mg/dL while serum triglyceride ≥200 mg/dL was associated with a 11% increased hazard for death (95% CI 1.01–1.22). Age modified the association between serum triglyceride levels ≥200 mg/dL and mortality with patients <65 years having a 38% higher hazard for death (95% CI 1.15–1.65) and ≥65 years with no increased risk for death (HR 0.97, 95% CI 0.88–1.08, P for interaction <0.001). When serum triglycerides were examined as a continuous log-transformed variable, similar associations with mortality were noted.


Serum triglyceride ≥200 mg/dL was independently associated with all-cause mortality in Stage 3 and Stage 4 CKD patients aged <65 years but not among patients of age ≥65 years. Future studies should confirm these findings and examine the mechanisms that may explain these associations.
