Abstract:
The in vitro effects of ceftibuten on human polymorphonuclear leukocyte (PMN) chemotaxis, phagocytosis and chemiluminescence were investigated. PMN from healthy adult donors were incubated for 1 h in medium alone or in medium containing increasing concentrations of ceftibuten (4, 8 and 40 times the MIC for Escherichia coli). Up to 40 MIC ceftibuten did not significantly interfere with the function of PMN.
Insights
Ceftibuten, an antibiotic, did not significantly impact human polymorphonuclear leukocyte (PMN) functions like chemotaxis or phagocytosis in vitro. This suggests ceftibuten may not impair crucial immune cell activities at tested concentrations.
Area of Science:
- Pharmacology
- Immunology
- Microbiology
Background:
- Human polymorphonuclear leukocytes (PMNs) are critical immune cells.
- Antibiotics can potentially affect immune cell functions.
- Ceftibuten is a cephalosporin antibiotic.
Purpose of the Study:
- To investigate the in vitro effects of ceftibuten on human PMN functions.
- To assess the impact of ceftibuten on PMN chemotaxis, phagocytosis, and chemiluminescence.
Main Methods:
- Human PMNs from healthy donors were used.
- Cells were incubated with varying concentrations of ceftibuten (4, 8, and 40 times the MIC against E. coli).
- PMN chemotaxis, phagocytosis, and chemiluminescence were measured.
Main Results:
- Ceftibuten, even at 40 times the minimum inhibitory concentration (MIC) for Escherichia coli, did not significantly interfere with PMN functions.
- No significant impairment of PMN chemotaxis, phagocytosis, or chemiluminescence was observed.
Conclusions:
- Ceftibuten appears to have minimal in vitro impact on key human PMN functions.
- These findings suggest ceftibuten may not adversely affect crucial innate immune responses mediated by PMNs.
