Observational studyHumans

Design
Observational study
Subjects
Patients with end-stage renal disease on maintenance haemodialysis; number not stated in the abstract
Dose used in the study
Not applicable; palmitoylethanolamide was measured in serum, not given
Duration
12-month follow-up for mortality
What was measured
Serum oleoylethanolamide and palmitoylethanolamide, correlations with clinical and laboratory indices, and association with 12-month all-cause mortality

What the authors reported

This observational study found:

  • Both lipids correlated positively with HDL cholesterol and negatively with body fat and anthropometric measures.
  • Oleoylethanolamide correlated with IL-6 (rho 0.19; p=0.004), and PEA showed a similar non-significant trend (rho 0.12; p=0.07).
  • Serum PEA of 4.7 pmol/mL or higher was associated with higher mortality after adjustment (hazard ratio 2.99; 95% CI 1.04 to 8.64).

Limits of this study

An observational study of the body's own PEA levels in dialysis patients; it did not test PEA supplements and cannot show cause. The sample size is not stated in the abstract. Three authors are inventors on a related patent application filed by the University of California, Irvine.
