<jats:title>ABSTRACT</jats:title>
<jats:p>
The worrisome increase in Gram-negative bacteria with borderline susceptibility to carbapenems and of carbapenemase-producing
<jats:named-content xmlns:xlink="http://www.w3.org/1999/xlink" content-type="genus-species" xlink:type="simple">Enterobacteriaceae</jats:named-content>
has significantly undermined their efficacy. Continuous infusion may be the best way to maximize the time-dependent activity of meropenem. The aim of this study was to create dosing nomograms in relation to different creatinine clearance (CL
<jats:sub>Cr</jats:sub>
) estimates for use in daily clinical practice to target the steady-state concentrations (
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
s) of meropenem during continuous infusion at 8 to 16 mg/liter (after the administration of an initial loading dose of 1 to 2 g over 30 min). The correlation between meropenem clearance (CL
<jats:sub>m</jats:sub>
) and CL
<jats:sub>Cr</jats:sub>
was retrospectively assessed in a cohort of critically ill patients (group 1,
<jats:italic>n</jats:italic>
= 67) to create a formula for dosage calculation to target
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
. The performance of this formula was validated in a similar cohort (group 2,
<jats:italic>n</jats:italic>
= 56) by comparison of the observed and the predicted
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
s. A significant relationship between CL
<jats:sub>m</jats:sub>
and CL
<jats:sub>Cr</jats:sub>
was observed in group 1 (
<jats:italic>r</jats:italic>
= 0.72,
<jats:italic>P</jats:italic>
< 0.001). The application of the formula to meropenem dosing in group 2, infusion rate (g/24 h) = [0.078 × CL
<jats:sub>Cr</jats:sub>
(ml/min) + 2.85] × target
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
× (24/1,000), led to a significant correlation between the observed and the predicted
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
s (
<jats:italic>r</jats:italic>
= 0.92,
<jats:italic>P</jats:italic>
< 0.001). Dosing nomograms based on CL
<jats:sub>Cr</jats:sub>
were created to target the meropenem
<jats:italic>C</jats:italic>
<jats:sub>ss</jats:sub>
at 8, 12, and 16 mg/liter in critically ill patients. These nomograms could be helpful in improving the treatment of severe Gram-negative infections with meropenem, especially in the presence of borderline susceptible pathogens or even of carbapenemase producers and/or of pathophysiological conditions which may enhance meropenem clearance.
