    Abstract:
    Cefodizime, a new aminothiazolylcephalosporin, has been shown to possess immunomodulating activity in many experimental models in vivo and in vitro. The in-vivo effect of the drug was evaluated in a model represented by the surgical patient, being surgical practices usually associated with an immunological impairment involving many aspects of the immune response. Two groups of ten subjects were treated respectively with cefodizime (2 g i.v. daily) and another cephalosporin (ceftriaxone) at the same dosage. Aspecific immunity (complement activity, neutrophil phagocytosis, chemiluminescence and superoxide anion production) and cell-mediated reactivity (lymphocyte subpopulations and E-rosette-forming cells) were evaluated before, and at predetermined intervals after, surgery and antibiotic treatment. In the control group an important immunological derangement is observed, involving both lymphocytes and neutrophil functions and complement system. The treatment with cefodizime displays a positive effect with a significant improvement of impaired functions. The effect of the drug particularly influences neutrophil phagocytosis, explored with both the NBT test and determinations of chemiluminescence, and the complement system, through both the classic and the alternative pathways. A slight effect is observed on lymphocyte functions.
