Modification of acquired immunity in mice by imipenem/cilastatin

The immunomodulating properties of antimicrobial drugs may have important implications for clinical practice, particularly for those patients whose immune system has been compromised. In this study, we assessed the influence of different treatments with a beta-lactam antibiotic (imipenem/cilastatin) on several acquired immune responses of BALB/c mice; splenocyte responses to specific mitogens and to sheep red blood cells, IL-2 production and proportions of the different lympho-monocytic populations. Impenem/cilastatin was shown to modify some lymphocyte-associated immune functions and it would be useful to investigate whether immunomodulatory effects also occur in humans.
