Aims: to assess oxidative stress in acute pancreatitis, its evolution over time and its relationship with the severity of the disease. Methods: during a two-year period, patients with acute pancreatitis with less than 24 hours of pain were evaluated. Serum was obtained the first, second and fourth day from admittance, if complications were detected, and after recovery. Malondialdehyde was determined by high performance liquid chromatography. Twenty healthy volunteers constituted the control group. Malondialdehyde between groups was compared with Mann-Whitney and Kruskal-Wallis tests; malondialdehyde evolution was studied with Wilcoxon test. Results: one hundred and sixty-nine patients were included (91 women, median age 67 years, range 20-95); 33 suffered a severe episode. Malondialdehyde decreased from first to fourth day (0.600 vs. 0.451 vs. 0.343 μM, respectively, p < 0.05). When complications were detected, malondialdehyde level was similar to that of first and second day (0.473 μM, p > 0.05). In severe attacks malondialdehyde was higher than in control group at day 2 (severe: 0.514; mild: 0.440; control: 0.347 μM, p < 0.05 severe vs. control). Conclusions: an early oxidative stress is observed in acute pancreatitis. In severe attacks, oxidative stress remains high longer than in mild episodes. The onset of complications is associated with high malondialdehyde concentration.
