The Role of Nanobiosensors in Therapeutic Drug Monitoring
Journal of Personalized Medicine Review Personalized Medicine for Antibiotics: The Role of Nanobiosensors in Therapeutic Drug Monitoring Vivian Garzón 1, Rosa-Helena Bustos 2 and Daniel G. Pinacho 2,* 1 PhD Biosciences Program, Universidad de La Sabana, Chía 140013, Colombia; [email protected] 2 Therapeutical Evidence Group, Clinical Pharmacology, Universidad de La Sabana, Chía 140013, Colombia; [email protected] * Correspondence: [email protected]; Tel.: +57-1-8615555 (ext. 23309) Received: 21 August 2020; Accepted: 7 September 2020; Published: 25 September 2020 Abstract: Due to the high bacterial resistance to antibiotics (AB), it has become necessary to adjust the dose aimed at personalized medicine by means of therapeutic drug monitoring (TDM). TDM is a fundamental tool for measuring the concentration of drugs that have a limited or highly toxic dose in different body fluids, such as blood, plasma, serum, and urine, among others. Using different techniques that allow for the pharmacokinetic (PK) and pharmacodynamic (PD) analysis of the drug, TDM can reduce the risks inherent in treatment. Among these techniques, nanotechnology focused on biosensors, which are relevant due to their versatility, sensitivity, specificity, and low cost. They provide results in real time, using an element for biological recognition coupled to a signal transducer. This review describes recent advances in the quantification of AB using biosensors with a focus on TDM as a fundamental aspect of personalized medicine. Keywords: biosensors; therapeutic drug monitoring (TDM), antibiotic; personalized medicine 1. Introduction The discovery of antibiotics (AB) ushered in a new era of progress in controlling bacterial infections in human health, agriculture, and livestock [1] However, the use of AB has been challenged due to the appearance of multi-resistant bacteria (MDR), which have increased significantly in recent years due to AB mismanagement and have become a global public health problem [2]. -

Leisner* Department of Veterinary and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark The 1940s and 1950s witnessed a diverse search for not just natural product antibiotics but also for synthetic and semisynthetic compounds. This review revisits this epoch, using the research by a Danish pharmaceutical company, LEO Pharma, as an example. LEO adopted a strategy searching for synthetic antibiotics toward specific bacterial Edited by: Rustam Aminov, pathogens, in particular Mycobacterium tuberculosis, leading to the discovery of a University of Aberdeen, new derivative of a known drug. Work on penicillin during and after WWII lead to the United Kingdom development of associated salts/esters and a search for new natural product antibiotics. -

Van Matre1 , Shelby L. Evans2, Scott W. Mueller3, Robert MacLaren3, Douglas N. Fish3 and Tyree H. Kiser3,4* Abstract Background: Invasive fungal infections are a major cause of morbidity and mortality. Newer antifungals may provide similar efcacy with improved safety compared to older more established treatments. This study aimed to compare clinically relevant safety and efcacy outcomes in real world patients treated with isavuconazole, voriconazole, or posaconazole. Methods: This single center retrospective matched cohort study evaluated adults between January 2015 and Decem- ber 2017. The primary outcome was a composite safety analysis of antifungal related QTc prolongation, elevated liver function tests (> 5 times ULN), or any documented adverse drug event. Key secondary outcomes included: individual safety events, 30-day readmissions, magnitude of drug interactions with immunosuppressive therapy, and overall cost. Results: A total of 100 patients were included: 34 patients in the voriconazole group and 33 patients within each of the isavuconazole and posaconazole groups. The composite safety outcome occurred in 40% of the total cohort and was diferent between isavuconazole (24.2%), voriconazole (55.9%), and posaconazole (39.4%; p 0.028). Change in QTc (p < 0.01) and magnitude of immunosuppression dose reduction (p 0.029) were diferent between= the three groups. No diferences in mortality, length of stay, readmission, or infection= recurrence were observed between groups (p > 0.05 for all). -
Erythromycin Versus Tetracycline for Treatment of Mediterranean Spotted Fever

Both therapeutic regimens proved effective, but in patients treated with tetracycline both clinical symptoms and fever disappeared significantly more quickly. Likewise, when those patients who began treatment within the first 72 hours of illness are considered the febrile period had a significantly shorter duration in the group treated with tetracycline. One patient was switched to tetracycline because there was no improvement of clinical manifestations, with persistence of fever, myalgias, and prostration, after receiving eight days of treatment with erythromycin. These results suggest that tetracyclines are superior to erythromycin in the treatment of Mediterranean spotted fever. copyright.

General Items
Essential Medicines List (EML) 2019 Application for the inclusion of imipenem/cilastatin, meropenem and amoxicillin/clavulanic acid in the WHO Model List of Essential Medicines, as reserve second-line drugs for the treatment of multidrug-resistant tuberculosis (complementary lists of anti-tuberculosis drugs for use in adults and children) General items 1. Summary statement of the proposal for inclusion, change or deletion This application concerns the updating of the forthcoming WHO Model List of Essential Medicines (EML) and WHO Model List of Essential Medicines for Children (EMLc) to include the following medicines: 1) Imipenem/cilastatin (Imp-Cln) to the main list but NOT the children’s list (it is already mentioned on both lists as an option in section 6.2.1 Beta Lactam medicines) 2) Meropenem (Mpm) to both the main and the children’s lists (it is already on the list as treatment for meningitis in section 6.2.1 Beta Lactam medicines) 3) Clavulanic acid to both the main and the children’s lists (it is already listed as amoxicillin/clavulanic acid (Amx-Clv), the only commercially available preparation of clavulanic acid, in section 6.2.1 Beta Lactam medicines) This application makes reference to amendments recommended in particular to section 6.2.4 Antituberculosis medicines in the latest editions of both the main EML (20th list) and the EMLc (6th list) released in 2017 (1),(2). On the basis of the most recent Guideline Development Group advising WHO on the revision of its guidelines for the treatment of multidrug- or rifampicin-resistant (MDR/RR-TB)(3), the applicant considers that the three agents concerned be viewed as essential medicines for these forms of TB in countries. -

Both linezolid-resistant S. aureus (LRSA) and coagulase-negative staphylococci (CoNS) strains have been collected worldwide. Two isolates carrying linezolid resistance genes were recovered from laryngological patients and characterized by determining their antimicrobial resistance patterns and using molecular methods such as spa typing, MLST, SCCmec typing, detection of virulence genes and ica operon expression, and analysis of antimicrobial resistance determinants. Both isolates were multidrug resistant, including resistance to methicillin. The S. aureus strain was identified as ST- 398/t4474/SCCmec IVe, harboring adhesin, hemolysin genes, and the ica operon. The S. haemolyticus strain was identified as ST-42/mecA-positive and harbored hemolysin genes.
