Abstract

The in vitro and in vivo effects of ceftriaxone, a newly developed cephalosporin, on phagocytes and T-cell subsets were studied. Ceftriaxone in vitro did not interfere with phagocytosis, phagocytosis-dependent metabolic activation, and microbicidal activity (against Staphylococcus aureus and Candida albicans) of human neutrophils at doses ranging from 10 to 320 micrograms/ml. In vitro chemotaxis was markedly inhibited both in the presence of and after 30 minutes of exposure to 40 micrograms/ml of ceftriaxone. Six normal adult volunteers were given 2 g of antibiotic intravenously every 24 hours for six days. The in vivo effects of ceftriaxone on neutrophil functions and T-cell subsets were investigated before and 30 minutes after injection on the first and third days. No change in any phagocyte function (chemotaxis, phagocytosis, phagocytosis-dependent metabolic activation, and microbicidal activity) or in the distribution of T-cell subpopulations was observed.
