-IL-6 showed higher serum values in patients with gastroenteritis versus the control group (p < 0.001)-IL-6 showed higher serum values in patients with bacterial gastroenteritis versus the control group-Stool IL-6 in the group with proven bacterial etiology was significantly higher (p < 0.05)-IL-8 showed higher serum values in patients with gastroenteritis versus the control group-IL-8 tended to present higher values in the group of those with bacterial versus viral etiology.
