ABSTRACT
The proper and coordinated response of the host immune system to bacterial infections is known to play a central role in the eradication of an infection. Therefore, the impact of antibiotics on both innate and acquired host immunity may be involved in the therapeutic outcome. The aim of this study was to evaluate the effects of the widely used cephalosporin cefaclor on some parameters of the immune system in ex vivo conditions. The results demonstrated that short-term (3 to 6 days) treatment with this antibiotic induced pleiotropic modification of rat spleen cells upon ex vivo stimulation with the polyclonal mitogen PHA, entailing increased lymphoproliferative responses, augmented IFN-gamma, IL-2 and IL-10 synthesis and decreased production of IL-4 and IL-6 in comparison to spleen cells from control rats. The mononuclear spleen cells of healthy rats released larger amounts of IFN-gamma and IL-2 in culture supernatants in response to polyclonal mitogenic stimulation with PHA compared to the spleens of the control rats receiving vehicle only. Simultaneously, the treatment with cefaclor augmented PHA-induced lymphoproliferative responses and reduced the synthesis of IL-4 and IL-6. These data depict a type 1 cytokine inducing and immunostimulatory pharmacological profile that, by activating the innate and acquired immune system, would be synergistic with cefaclor antibacterial activity.
