Whilst micafungin (Mycamine®) has much to offer, little is known about its pharmacokinetic profile in ICU patients with specific co-morbidities such as obesity, hypoalbumenia, and severe liverfunction disturbances. Also, ICU patients are known to experience changes in pharmacokinetics (PK) due to changes in hemodynamics, extracorporeal elimination techniques, interacting comedication, etc. Based on criteria outlined below, micafungin may prove to be the drug of choice in this cohort of patients. Therefore it seems prudent to conduct a trial in a cohort of patients who receive micafungin but with co-variates that may be of influence to the pharmacokinetic profile. To build a valid pharmacokinetic model, all patients on micafungin will be included in the analysis and used for model building. Co-variates that will be explored are at least: obesitas, liverfunction, albumin, creatinin-clearance. Simulations will be performed to determine if adequate exposure is reached under different patho-physiological conditions.
In conclusion: this trial is on determining the PK of micafungin in a non-selected cohort of patients with suspected or proven invasive fungal infections. Most important covariates will be modelled using advanced mathematical techniques. Micafungin may prove to be beneficial over the other two echinocandins in terms of limited factors that impact PK. This has to be proven in a prospective trial.

ICU patient on micafungin
ICU patients with an invasive fungal infection on micafungin treatment
100mg/day infusion in 1 hour
Other Name: Mycamine
- micafunigin AUC [ Time Frame: Day 3 and Day 7 ]AUC0-tau [mg*g/L] of micafungin given to ICU patients. Other pharmacokinetic parameters will be assessed as well.
- covariates [ Time Frame: 17 days ]co-variates of influence on the pharmacokinetics of micafungin. Specific co-variates are of high interest to the researchers: high body weight (including obese patients, defined as BMI> 30 kg/m2), hypo-albuminaemia, clearance pathways, impact of extracorporeal clearance system (ECMO, CVVH).
- exposure [ Time Frame: 17 days ]To determine whether adequate exposure is attained in ICU patients
- number of adverse events [ Time Frame: 17 days ]To determine the safety of micafungin in this patient population
Biospecimen Retention: Samples Without DNA
