Experimental and clinical studies in sepsis indicate that antibiotic therapy may induce the release of endotoxin (LPS) from the outer membrane of gram-negative bacteria and therefore may affect the physiologic response and survival. The aim of this study was to evaluate if antibiotics commonly used to treat secondary peritonitis are capable of changing survival rates, proinflammatory and anti-inflammatory cytokine concentrations, and the release of endotoxin in a murine model of sepsis. Sepsis was induced by cecal ligation and puncture (CLP) in Swiss mice using an 18-gauge needle. The animals received injections of saline solution or imipenem or a combination of ciprofloxacin plus clindamycin every 8 h for 3 days. Antibiotic treatment induced an increase in survival rate and decreased plasma and peritoneal fluid levels of TNF-alpha and IL-6 at 6 and 24 h after CLP as compared with saline-treated animals. Antibiotic-treated animals also showed an early (6 h) decrease and a late (24 h) increase in IL-10 concentration in the peritoneal fluid. LPS concentrations were elevated in all groups, but imipenem-treated animals showed higher levels (2.2 EU/mL) than ciprofloxacin plus clindamycin (1.3 EU/mL) and saline-treated (1.5 EU/mL) groups. We conclude that antibiotic-induced endotoxin release is not a major determinant in the inflammatory response and prognosis in murine models of sepsis.
