Beta-Lactams Dosing In Pneumonia in ICU in Patients Treated by Continuous Renal Replacement Therapy: the BLIPIC Study (BLIPIC)

February 1, 2024 updated by: Centre Hospitalier de Valenciennes

Beta-Lactams Dosing In Pneumonia in ICU in Patients Treated by Continuous Renal Replacement Therapy

Pneumonia are the most frequent infections in ICU. Little is known about beta-lactam doses necessary for this infection for patients treated with continuous veino-veinous hemodialysis. The pharmacokinetic variability expose to over and underdosage leading to toxicity or therapeutic failure. The aim of this study is to define if beta-lactams doses used in pneumonia for patients with acute kidney injury treated with our hemodialysis conditions lead to beta-lactam therapeutic plasma levels.

Study Overview

Detailed Description

Pneumonia are the most frequent infections in ICU. Little is known about beta-lactam doses necessary for this infection for patients treated with continuous veino-veinous hemodialysis. The pharmacokinetic variability expose to over and underdosage leading to toxicity or therapeutic failure. The aim of this study is to define if beta-lactams doses used in pneumonia for patients with acute kidney injury treated with our hemodialysis conditions lead to beta-lactam therapeutic plasma levels.

This prospective observational multicenter study will include all patients with pneumonia treated by beta-lactam and continuous veino-veinous hemodialysis in 5 ICU. Blood sampling will be done at assumed pharmacokinetic steady state. Protocol sample concentrations of beta-lactams immediately prior to re-dosing, after 24 hours of association of intraveinous beta-lactam and continuous veino-veinous hemodialysis. Another sample will be done after 48 hours. The ICU measured bacterial MICs routinely when the pathogen will be determined. Surveyed ICUs will adopt SFM-EUCAST breakpoints for the targeted (or suspected) bacteria to determine pharmacokinetic/pharmacodynamic targets when a mesured MIC (Minimum inhibitory concentration) is not available. Local hospital antibiogram data can also be used to describe likely pathogen susceptibility. Target attainment is defined as 100% fT> 5 MIC. Due to the long delay to receive therapeutic drug monitoring results, doses could not be ajusted. Factors which could cause concentrations variations will be registered. When neurotoxicity is suspected, a sample will be realized to know beta-lactam concentration and the adverse event will be notified.
