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]. -
Comparison of Arbekacin and Vancomycin in Treatment of Chronic Suppurative Otitis Media by Methicillin Resistant Staphylococcus Aureus
ORIGINAL ARTICLE Infectious Diseases, Microbiology & Parasitology http://dx.doi.org/10.3346/jkms.2015.30.6.688 • J Korean Med Sci 2015; 30: 688-693 Comparison of Arbekacin and Vancomycin in Treatment of Chronic Suppurative Otitis Media by Methicillin Resistant Staphylococcus aureus Ji-Hee Hwang,1 Ju-Hyung Lee,2,4 Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of ear infections. We Jeong-Hwan Hwang,3 Kyung Min Chung,5 attempted to evaluate the clinical usefulness of arbekacin in treating chronic suppurative Eun-Jung Lee,6 Yong-Joo Yoon,4,6 otitis media (CSOM) by comparing its clinical efficacy and toxicity with those of Mi-Kyoung Moon,1 Ju-Sin Kim,1 vancomycin. Efficacy was classified according to bacterial elimination or bacteriologic 1 3,4 Kyoung-Suk Won, and Chang-Seop Lee failure and improved or failed clinical efficacy response.

Allosteric Drug Transport Mechanism of Multidrug Transporter Acrb
ARTICLE https://doi.org/10.1038/s41467-021-24151-3 OPEN Allosteric drug transport mechanism of multidrug transporter AcrB ✉ Heng-Keat Tam 1,3,4 , Wuen Ee Foong 1,4, Christine Oswald1,2, Andrea Herrmann1, Hui Zeng1 & ✉ Klaas M. Pos 1 Gram-negative bacteria maintain an intrinsic resistance mechanism against entry of noxious compounds by utilizing highly efficient efflux pumps. The E. coli AcrAB-TolC drug efflux pump + 1234567890():,; contains the inner membrane H /drug antiporter AcrB comprising three functionally inter- dependent protomers, cycling consecutively through the loose (L), tight (T) and open (O) state during cooperative catalysis. Here, we present 13 X-ray structures of AcrB in inter- mediate states of the transport cycle. Structure-based mutational analysis combined with drug susceptibility assays indicate that drugs are guided through dedicated transport chan- nels toward the drug binding pockets. A co-structure obtained in the combined presence of erythromycin, linezolid, oxacillin and fusidic acid shows binding of fusidic acid deeply inside the T protomer transmembrane domain. Thiol cross-link substrate protection assays indicate that this transmembrane domain-binding site can also accommodate oxacillin or novobiocin but not erythromycin or linezolid. AcrB-mediated drug transport is suggested to be allos- terically modulated in presence of multiple drugs. 1 Institute of Biochemistry, Goethe-University Frankfurt, Frankfurt am Main, Germany. 2 Sosei Heptares, Steinmetz Building, Granta Park, Great Abington, Cambridge, UK. 3Present -

In uncomplicated UTIs Escherichia coli is the leading organism, Urinary tract infections (UTI) whereas in complicated UTIs the bacterial spectrum is much broader Uncomplicated and including Gram-negative and Gram-positive and often multiresistant complicated UTI organisms. The therapy of uncomplicated UTIs is almost exclusively Antibiotic resistance of antibacterial, whereas in complicated UTIs the complicating factors uropathogens have to be treated as well. There are two predominant aims in the Antibiotic treatment antimicrobial treatment of both uncomplicated and complicated UTIs: New antiinfectives for (i) rapid and effective response to therapy and prevention of recurrence treatment of UTI of the individual patient treated; (ii) prevention of emergence of resis- tance to antimicrobial chemotherapy in the microbial environment. The main drawback of current antibiotic therapies is the emergence and rapid increase of antibiotic resistance. To combat this development several strategies can be followed. Decrease the amount of antibiotics administered, optimal dosing, prevention of infection and development of new antibiotic substances. -

In kanamycin (KM)-group AGs tested [KM, dibekacin (DKB), amikacin and arbekacin (ABK)], ABKretained activity after acetylations by AAC(3), AAC(2') and AAC(6'). DKBalso retained a weak activity after acetylation by AAC(2'). In gentamicin (GM)-group AGs tested [GM, micronomicin, sisomicin (SISO), netilmicin (NTL) and isepamicin], GM, SISO and NTL retained activites after acetylation by AAC(2'). In neomycin (NM)-group AGs tested [ribostamycin, NM,paromomycin], NMretained activity after acetylation by AAC(6') and AAC(2'). None of astromicin (ASTM)-group AGs tested (ASTMand istamycin B) retained activity after acetylation by AAC(2') and AAC(6'). The activities of acetylated ABK derivatives by AAC(3) and AAC(2') were distinctively high, compared to the others. Streptomyces lividans TK21containing the cloned aac genes were markedly sensitive to AGs that retained activities after acetylation, indicating the substantial effect of 'double stage activity'.
