dc.description.abstractBackground: Sepsis is a state of augmented oxidative stress and diminished antioxidant capacity. High den- sity lipoprotein (HDL) particles were shown to possess antioxidant and anti-inflammatory properties, as well as Paraoxonase 1 (PON1), which is an enzyme that is also protective against HDL oxidation. Previous stud- ies suggested a possible role of decreased PON1 activ- ity or HDL levels in sepsis patients. Aims: The present study was designed to test a hypoth- esis that higher PON1 activity and HDL-cholesterol levels could predict a better survival in sepsis patients. Study Design: Observational study. Methods: Venous blood samples were collected from sepsis patients for HDL-cholesterol levels, PON1 ac- tivity and cytokine assays (TNF-α and IL-6) and Acute Physiologic and Chronic Health Evaluation II (APACHE II) scores were calculated in order to weight patients’ disease severity on the day of sepsis diagnosis. Patients were followed-up until the 28th day for any cause intra- hospital mortality. Data were statistically analyzed for effects of study parameters on patients’ survival. Results: In total, 85 patients with sepsis were included in the study. The mean age was 65.2±17.9 years and 48 were male; at the end of the 28-day follow-up pe- riod, 46 survived. TNF-α (86.9±10.5 vs 118.6±16.4) and IL-6 levels (906.7±82.7 vs 1323.1±54.3) were sig- nificantly higher in non-survivors, while PON1 activity (140.7±42.3 vs 66.7±46.6) and HDL-cholesterol lev- els (43.6±8.1 vs 34.5±8.9) were significantly higher in survivors (p<0.001 for all). TNF-α (r=-0.763) and IL-6 levels (r=-0.947) showed strong negative correlations, PON1 activity (r=0.644) and HDL-cholesterol levels (r=0.477) showed positive correlations with patient sur- vival (p<0.001 for all). Survival estimates significantly favored TNF-α (Log Rank 59.5, p<0.001) and IL-6 levels (Log Rank 53.2, p<0.001) according to PON1 activity (Log Rank 5.4, p<0.03) and HDL-cholesterol levels (Log Rank 8.3, p<0.005). Regression analyses for relative contributions of parameters to survival showed that higher IL-6 levels (t:-16.489, p<0.001) were the most significant negative factor for survival, and TNF-α levels (t:-4.417, p<0.001), whereas PON1 activity had a positive effect (t:3.210, p<0.003). Conclusion: The present study showed that although low PON1 activity and HDL-cholesterol levels were related to mortality, higher levels were not found to be as predictive as cytokine levels for survival.en_US
