Aging is a dynamic process, in which morphological and physiological changes occur at all levels, making the body more vulnerable to acute events. Elderly people are at greater risk of sepsis developing than younger people. Sepsis is a set of serious manifestations throughout the body produced by an infection, leading to events that compromise cell homeostasis as oxidative stress and is associated with organ dysfunction. The aim of this study was to evaluate multi-organ oxidative stress in old rats in an animal model of polymicrobial sepsis. Adult (60d) and old (210d) male Wistar rats were submitted to sepsis by cecal ligation and perforation (CLP) and control group (sham) only by laparotomy. The experimental groups were divided into sham 60d, sham 210d, CLP 60d and CLP 210d. Twenty-four hours after CLP, myeloperoxidase (MPO) activity, oxidative damage to lipids and proteins, superoxide dismutase (SOD) and catalase (CAT) activities were evaluated in the lung, kidney, liver, heart, spleen, quadriceps and diaphragm. Aging potentiated the increase in MPO activity in the after sepsis in the lung, liver and spleen. Lipid oxidative damage occurred in all structures analyzed in the CLP groups, while only in the lung, liver and diaphragm the lipid peroxidation was higher in the CLP 210d group compared to 60d. Regarding protein damage, this potentiation happened only in the lung. The SOD activity in the lung, kidney, spleen and diaphragm there was a significant decrease in the CLP 210d group compared to the sham 60d group while in the CAT only in the lung and kidney. The findings in this study indicate that increasing age potentiated oxidative damage in different organs after sepsis by intensifying the presence of neutrophils, which possibly increased the damage to lipids and proteins with reduced activity of SOD and CAT.
