ABSTRACT
OBJECTIVE:
To characterize the in vitro elution of amikacin and Dispersin B (ß-N-acetylglucosaminidase) in a degradable hydrogel. STUDYDESIGN:
In vitro, prospective study.METHODS:
Amikacin (group A; 40 mg/mL), Dispersin B (group D; 70 µg/mL), or combined amikacin and Dispersin B (group AD; 40 mg/mL and 70 µg/mL, respectively) were added to a hydrogel. Ten aliquots per group were incubated in phosphate-buffered saline that was exchanged at 1, 4, 8, 12, and 24 hours and then once daily for 10 days. Eluted amikacin and Dispersin B were quantitated by using an amikacin reagent kit and a Dispersin B enzyme-linked immunosorbent assay kit, respectively. Time point drug concentrations were compared between groups by using repeated-measures analysis of variance, and total drug elution was compared by using an area under the curve calculation.RESULTS:
Amikacin alone, Dispersin B alone, and amikacin and Dispersin B combined together underwent rapid elution in the first 24 hours, followed by a gradual decrease over 10 days. The concentration of Dispersin B eluted in group D was higher at 1 day and lower from day 5 to day 10 compared with that in group AD. The concentration of amikacin eluted in group A was higher at 1, 4, and 8 hours and on day 10 and lower on day 1 compared with that in group AD. The total elution of amikacin was greater from group AD compared with that from group A (P = .02).CONCLUSION:
Combining amikacin and Dispersin B had an affect on the total elution of amikacin but not Dispersin B. CLINICALSIGNIFICANCE:
The combination of amikacin and Dispersin B in a degradable hydrogel could allow local treatment of complex infections without the requirement for multiple invasive procedures.
