Aminoglycoside antibiotics moderately impair granulocyte function
Antimicrobial Agents and Chemotherapy
|March 1, 1978
Abstract:
By in vitro methods, five aminoglycoside antibiotics (amikacin, kanamycin, gentamicin, tobramycin, and netilmicin) were shown to produce modest changes in granulocyte adherence (increase) and migration (decrease) and no change in phagocytosis or nitroblue tetrazolium reduction.
Insights
Five aminoglycoside antibiotics modestly increased granulocyte adherence and decreased migration in vitro. These drugs did not affect phagocytosis or nitroblue tetrazolium reduction in the study.
Area of Science:
- Immunology
- Pharmacology
- Microbiology
Background:
- Aminoglycoside antibiotics are crucial for treating bacterial infections.
- Understanding their impact on host immune cells, like granulocytes, is important for assessing treatment efficacy and potential side effects.
Purpose of the Study:
- To investigate the in vitro effects of five common aminoglycoside antibiotics on key granulocyte functions.
Main Methods:
- Utilized in vitro assays to assess granulocyte adherence, migration, phagocytosis, and nitroblue tetrazolium reduction.
- Tested five aminoglycoside antibiotics: amikacin, kanamycin, gentamicin, tobramycin, and netilmicin.
Main Results:
- Aminoglycoside antibiotics demonstrated modest increases in granulocyte adherence.
- A decrease in granulocyte migration was observed with these antibiotics.
- No significant changes were found in granulocyte phagocytosis or nitroblue tetrazolium reduction.
Conclusions:
- Aminoglycoside antibiotics exert specific, modest modulatory effects on granulocyte adherence and migration in vitro.
- These findings suggest that while aminoglycosides may influence neutrophil mobility, their impact on key bactericidal functions like phagocytosis and oxidative burst is minimal.
