Special Issue Information

Dear Colleagues,

TDM is frequently used in internal medicine, oncology and neurology. Although it has affected anti-infective agents since its inception, only in the last two decades has there been a greater use of TDM in the infectious diseases. TDM could help clinicians to administer correctly anti-infective drugs with a low therapeutic index.

Antimicrobial resistance represents one of the most major concerns to date and could lead to a dramatic global increase in mortality. Many efforts have been undertaken by scientific societies, which have led to antimicrobial stewardship and infection control. The use of TDM can be a great help for clinicians by allowing the effectiveness of a drug to be optimized, thereby reducing the onset of antimicrobial resistance; this advantage, already in physiological conditions, is even more noticeable in pathological conditions, such as during changes in the kinetics and dynamics of drugs (sepsis, pregnancy, cirrhosis, metabolic diseases, etc.); finally, the increase in medicalization of the global population has led to an increase in drug–drug interactions, which can be minimized with TDM.

The aim of this Special Issue is to focus on any aspects of TDM: pharmacokinetics and pharmacodynamics implications, clinical applications (in bacterial, fungal or viral infections), and real-life approaches in low-resource hospitals.
Different type of articles are welcome: original works, case reports, case series, qualitative and/or quantitative reviews of the current literature.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antibiotics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Meropenem (MRP)-Vaborbactam (VBR) is a novel beta-lactam/beta-lactamase inhibitor used for the management of difficult-to-treat Gram-negative infections. Among critically ill patients, MRP-VBR shows remarkable inter-individual variability in pharmacokinetic behavior, thus justifying the implementation of therapeutic drug monitoring (TDM) for improving real-time management in different [...] Read more.
Meropenem (MRP)-Vaborbactam (VBR) is a novel beta-lactam/beta-lactamase inhibitor used for the management of difficult-to-treat Gram-negative infections. Among critically ill patients, MRP-VBR shows remarkable inter-individual variability in pharmacokinetic behavior, thus justifying the implementation of therapeutic drug monitoring (TDM) for improving real-time management in different challenging scenarios. In this study, we developed and validated a fast and sensitive Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) method for the simultaneous quantification of MRP and VBR in human plasma microsamples of 3 microliters. The analysis required only a single-step sample preparation and was performed by means of a fast chromatographic run of 4 min, followed by positive electrospray ionization and detection on a high-sensitivity triple quadrupole tandem mass spectrometer operated in multiple reaction monitoring modes. The straightforward analytical procedure was successfully validated, based on the EMA guidelines, in terms of specificity, sensitivity, linearity, precision, accuracy, matrix effect, extraction recovery, the limit of quantification, and stability. The novel method was successfully applied for simultaneously measuring MRP and VBR concentrations in more than 42 plasma samples collected from critically ill patients affected by carbapenem-resistant Gram-negative bacteria infections.
