N2 - Background: Circulating levels of pro-inflammatory advanced glycation end products (AGEs) are increased in diabetes and other conditions characterized by chronically elevated oxidant stress (OS). OS also increases after acute trauma and is implicated in the development of complications such as multiple organ failure. Herein, we assess the effect of acute OS on circulating levels of AGEs in a cohort of acute trauma victims. Methods: An observational study was performed at a large Level 1 Trauma Center. Blood samples for measurement of two AGEs, carboxymethyllysine (CML) and methylglyoxal (MG), were obtained at admission, and serially afterwards in patients admitted to the ICU. Demographics, dietary history, markers of injury severity and ICU morbidity and mortality data were collected. Results: One hundred and fifty-six trauma patients (TP) (age: 39 ± 17 years, 83% males, injury severity score: 18 ± 14) were included in the study. TP had significantly higher serum AGE levels than normal healthy controls (CML, TP 12.4 ± 8.2 U/mL vs. controls 8.9 ± 5.3 U/mL, p < 0.001; MG, TP 2.1 ± 1.4 nmol/mL vs. controls 0.79 ± 0.3 nmol/mL, p < 0.001). Admission serum AGE levels in 49 severe TP admitted to the ICU were lower than those who were not. However, among the ICU patients, serum AGEs increased further for about 7 days in patients with an uncomplicated course, and remained markedly elevated in those with a complicated course. Conclusions: Circulating AGEs are transiently increased after acute trauma and persistently elevated AGE levels are associated with greater severity of injury.
