  • Title: The effects of aminoglycoside antibiotics on platelet aggregation and blood coagulation.
    Author: Chen G, Fei X, Ling J.
    Journal: Clin Appl Thromb Hemost; 2012 Sep; 18(5):538-41. PubMed ID: 22327814.
    Abstract:
    OBJECTIVE: To investigate the effects of different aminoglycoside antibiotics on platelet aggregation and blood coagulation, as well as the underlying mechanisms. METHOD: Blood samples were collected and prepared as platelet-rich plasma and platelet-poor plasma samples. Then assigned into different groups for the following antibiotics treatments: gentamicin, streptomycin, etimicin, amikacin, and kanamycin, as group 0 mg/L, group 30 mg/L, group 91mg/L, and group 910 mg/L for each drugs. The maximum platelet aggregation rate induced by adenosine diphosphate, expression levels of CD62p and FIB-R, prothrombin time, activated partial thromboplastin time, thrombin time, and fibrinogen were measured. The sodium citrate and sodium heparin were used in whole blood tests for the whole blood coagulation time as well as the Ca(2+) in blood plasma. RESULTS: Amikacin and gentamicin could inhibit the aggregation of platelets, which contributed to the whole blood clotting disorder. CONCLUSION: Amikacin and gentamicin might inhibit the platelet aggregation by blocking the activation and release of FIB-R or probably the inhibition of endogenous clotting factor as well. This effect was not dependent on calcium ions.
