In vitro effect of amikacin, imipenem, cefodizime, IFNalpha-2a alone and combinations of antibiotics with IFNalpha-2a on polymorphonuclear leukocyte function in chronic hepatitis patients.

The in vitro effect of amikacin (8 microg/ml), imipenem (30 microg/ml), cefodizime (10 microg/ml), interferon alpha-2a (IFNalpha-2a) (10 IU/ml) and antibiotic combinations with IFNalpha-2a on polymorphonuclear leukocyte (PMN) functions (phagocytosis and intracellular killing of Candida albicans blastospores) was investigated in chronic hepatitis B patients. Phagocytosis and candidacidal activity was not affected after pretreatment of PMNs with amikacin and imipenem (p > 0.05). Phagocytic activity was enhanced after pretreatment of PMNs with cefodizime and IFNalpha-2a compared with that of control PMNs (p < 0.05), but candidacidal activity was not affected by the same drugs (p > 0.05). Phagocytic and intracellular activity of PMNs were not affected by combinations of IFNalpha-2a and antibiotics (p > 0.05).
