| Description
| - Oxidative stress has been implicated in the pathogenesis of chronic pancreatitis (CP) and pancreatic cancer (PC). The study aim was to assess the oxidative stress markers and antioxidant defense system in patients with CP and those with PC. Activities of superoxide dismutase I (SODl), catalase (CAT), glutathione peroxidase I (GPXl), glutathione reductase (GR), arylesterase (PON1-A) and lactonase (PONl-L) activities of paraoxonase 1 (PONl) and concentrations of reduced glutathione, conjugated dienes in low density lipoprotein (CD/LDL) and oxidized LDL (ox-LDL/LDL) were assessed in 50 PC and 50 CP patients and 50 age and sex-matched controls. Comparison of PC and CP groups to controls found the following changes: glulathione peroxidase 1 (GPXl) (-20.2 %, -25.5 %; P < 0.001), glutathione reductase (GR) (-9.5 %, -11.9 %; P < 0.05), SOD1 (+22.9 %; P < 0.01), CAT(-10.6 %; P < 0.05), PON1-A (-34.3 % -16.0 %; P < 0.001), PONl-L (-44.2%; -17.0%; P < 0.01), conjugated dienes in LDL (CD/LDL) (+20 %, +33.3 %; P < 0.05) and ox-LDL/ LDL (+42.2 %, +14.4 %; P < 0.05). The patients with PC had changed activities and levels of SOD1 (+24.2 %), CAT (-10.4); P < 0.01), PONl -A (-21.7 %), PONl-L (-32.9 %), and ox-LDL/LDL (+24.3 %); (all P < 0.01) compared with the patients with CP. Reduced antioxidant defense system capacity and increased markers of oxidative stress were found in PC and CP. PONl-L and CAT activities, along with ox-LDL/LDL levels, were the independent factors differentiating the patients with PC from the patients with CP.
