Prospective Observational Pilot-study for the Evaluation of the Nephro- an Neurotoxicity in the Anti-infectious Therapy With Inhalative Colistin Therapy for Patients With Ventilator-associated Pneumonia (VAP) (LOKALE)

2. august 2016 opdateret af: Maria Deja, Charite University, Berlin, Germany

Multi-Drug resistant pathogens (MDR) are reported worldwide with increasing incidence, especially in intensive care settings.

One of the drugs which are effective against MDRs, is colistin (polymyxin E). This agent has been reintroduced in response to the increase of MDR pathogens and might be used more often in the future. Data on safety regarding the most important side effects are not sufficiently available. l This study evaluates the toxicity in patients who receive aerosolized colistin.

Detaljeret beskrivelse

There is growing evidence that patients in the ICU setting have a special risk profile for consecutive colonization and possible infection due to MDR pathogens.

One therapy option is the use of inhalative colistin, as this agent has been demonstrated to be effective against these pathogens. Data on pharmacodynamics or - kinetics are transferred from older studies or from other patient populations. For patients with pulmonary colonization or infection due to an MDR pathogen the systemic resorption of the drug is not known, consequently systemic side effects including kidney or neural damage are not predictable.

This study focus on patients with inhalative colistin therapy and uses therapeutic drug monitoring to determine the rate of systemic resorption of colistin. For the evaluation of neurotoxicity function of peripheral nerves (neve conduction velocity) and of the eighth cranial nerve is monitored. Nephrotoxicity is estimated by creatinine level (-clearance) and the RIFLE criteria.
