Abstract
Despite extensive research, the mortality associated with sepsis in hospitals remains very high. We have evaluated the protective immunomodulatory effect of thalidomide alone or with Augmentin in Klebsiella pneumoniae B5055-induced sepsis in BALB/c mice. The mouse model of sepsis was developed by placing K. pneumoniae B5055 entrapped in fibrin and thrombin clots in the peritoneal cavity of mice. The septic mice were treated with thalidomide alone (30 mg/kg/day/po), Augmentin alone (20 μg/ml/ip) and with their combination. The thalidomide-alone treated mice showed 75% survival whereas 60% of the Augmentin-alone treated group survived. Combination treatment provided 100% survival. Treatment with thalidomide alone significantly (p<0.05) decreased interleukin-1 α (IL-1α), nitric oxide (NO) and malondialdehyde (MDA) levels in the serum without significantly (p<0.05) decreasing the bacterial count in blood. Augmentin alone only decreased the bacterial load in blood significantly (p<0.05). However, a combination of thalidomide with Augmentin significantly (p<0.05) decreased both the bacterial count and inflammatory mediators.
