Resumen:
Adrenal insufficiency in patients with insulin resistance(IR) could affect the body´s response to stressful situations. Administrationof sucrose in the drinking water (DRS), to rodents, constitutes a valid modelfor human IR as it reproduces many of its characteristics. The aim of thepresent study was to analyze the HPA axis response in DRS-treated ratssubjected to a ligation and cecal puncture procedure (CLP), a very wellcharacterized sepsis model.Adult male Wistar rats were randomly distributed in sixgroups: Control, DRS, Control-Sham, Control-CLP, DRS-Sham and DRS-CLP. Rats inDRS groups received 30% sucrose for 15 weeks. IR was determined during the 10thweek by an insulin tolerance test. Sham or CLP surgeries were performed duringthe 15th week. For the following 24 hours before sacrifice, animalswere observed and body temperature was measured. Results indicate that surgery induces a significant increasein serum corticosterone levels in all groups (p
