title: The immunomodulatory effects of gentamicin, imipenem, piperacillin and amphotericin B on LAK effector function in vitro.
abstract: An understanding of the immunomodulating effects of anti-microbial regimens on recombinant interleukin-2 (rIL-2) induced peripheral leukocyte function, i.e. lymphokine-activated killer (LAK)-cell efficacy, would be clinically useful in the selection of commonly employed bone marrow transplantation (BMT) antibiotics to avoid post-transplant complications and optimize anti-microbial, anti-viral, anti-tumor therapies. In this report we evaluated the modulatory effects of a number of antibiotics used in BMT on LAK-cell cytotoxicities, in vitro. Our data showed that, even at serum trough titer, amphotericin B was significantly (P < or =0.05) immunostimulatory, whereas gentamicin, imipenem, and piperacillin, individually, were significantly (P < or =0.05) immunosuppressive. Statistical analysis detected no modulation due to aztreonam, amikacin, cotrimoxazole, or ceftazidime, or any of the six cephalosporins tested at molar equivalent concentration. We conclude that certain antibiotics may be more suitable for infection prone BMT hosts.
