Clinical Trial Summary

Bioelectrical impedance analysis is studied as a bedside tool to estimate capillary leak in order to guide dosing of hydrophilic antimicrobials.


Description:

Abstract Background: Recent data suggest that antimicrobial pharmacokinetics (PK) like volume of distribution (Vd) or drug clearance (CL) is extremely altered in critically ill patients with sepsis or septic shock due to pathophysiological alterations (e.g. influence on fluid status). Bioelectrical impedance analysis (BIA) was recently introduced as a simple, non-invasive, bedside technique to assess hydration status. The primary aim of the present study was to explore the correlation between BIA parameters and Vd of hydrophilic antimicrobial agents in critically ill patients. Furthermore, the relationship between BIA measurements and clinical observations was evaluated.

Methods: We performed a validation study in healthy volunteers in September 2015 that confirmed the reproducibility of BIA. Subsequently, a prospective observational study was carried out in eligible patients treat-ed with amoxicillin/clavulanic acid, meropenem, piperacillin/tazobactam or vancomycin, admitted at the in-tensive care unit (ICU) of the University Hospitals Leuven from October 2015 to March 2016. BIA measurement was performed on the same day as the collection of blood samples to calculate PK parameters of the administered antibiotic.

Outcome

Type Measure Description Time frame Safety issue
Primary Correlation between BIA parameters and Vd of hydrophilic antimicrobial agents Extracellular water (ECW), intracellular water, total body water (TBW), all expressed in liter, and ECW expressed as % of TBW will be correlated with Vd (L/kg) of vancomycin, meropenem, amoxicillin/clavulanic acid and piperacillin/tazobactam 6-12 hours (= dosing interval) depending on the antimicrobial studied
Secondary Correlation between BIA assessed hydration status and clinical observations Hydration status measured by BIA (dehydrated, normohydrated, hyperhydrated) will be correlated with SOFA score and cumulative fluid balance (L) 1 day
