PON3 and triple-A syndrome: Previously, in a case–control design within a population-based screening cohort of patients with AAA, Memon and colleagues identified a significant increase of 21 biomarkers of proteolysis, oxidative stress, lipid metabolism, and inflammation that was associated with AAA diameter and growth, as well as a decrease of paraoxonase-3.40 We did not find an overlap between the biomarkers identified in that study and our results in watchful waiting patients, which may in part be explained by the different study design.
