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]. -

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.

Belgian Veterinary Surveillance of Antibacterial Consumption
Belgian Veterinary Surveillance of Antibacterial Consumption National consumption report 2013 1 Summary This fifth BelVetSAC report, covers the results of the data collection on veterinary antibacterial consumption in Belgium in the year 2013. Data consist of all veterinary antibacterials sold to a veterinarian or pharmacist in Belgium and of antibacterial premixes incorporated in medicated feed intended to be used in Belgium for the year 2013. It includes thus consumption data for farm animals as well as companion animals. The denominator for animal production was the biomass (in kg) calculated as the sum of the amount of beef, pork and poultry meat produced in 2013, plus the number of dairy cattle present in Belgium times 500 kg of metabolic weight per head. As the usage data are concerned, this report shows for the second year in a row a decrease in the total consumption of antibacterial compounds in veterinary medicine of -6,6% between 2012 and 2013. Due to the relative stable animal production (expressed in biomass -0,3%) the decrease expressed in mg/kg biomass is -6,3%. When using 2011 as a reference, a reduction of -12,7% (expressed in mg/kg biomass) was achieved between 2011 and 2013, distributed over a reduction of -13,3% in antibacterial pharmaceuticals and -10,2% in antibacterial premixes. When looking more in detail to the different types of antibacterials used, it is observed that the penicillines (31,1%), sulphonamides (28,7%), and tetracyclines (24,1%) remain the three most used antibacterial classes. This year a substantial decrease in sulphonamide plus trimethoprim use and a limited decrease in penicillin and tetracycline use was observed. -

Among the different antibiotic classes, tetracyclines and sulfonamides are two of the most used for veterinary proposals. Due to the fact that these compounds are poorly absorbed in the gut of animals, a significant proportion (up to ~90%) of them are excreted unchanged, thus reaching the environment mainly through the application of manures and slurries as fertilizers in agricultural fields. Once in the soil, antibiotics are subjected to a series of physicochemical and biological processes, which depend both on the antibiotic nature and soil characteristics. Adsorption/desorption to soil particles and degradation are the main processes that will affect the persistence, bioavailability, and environmental fate of these pollutants, thus determining their potential impacts and risks on human and ecological health. -

Division of Marine Biotechnology, Asia-Pacific Ocean Research Center, National Sun Yat-Sen University, Kaohsiung, Taiwan, R.O.C. 2. National Museum of Marine Biology and Aquarium, Pingtung, Taiwan, R.O.C. (Received: August 30, 2010; Accepted: April 26, 2012) ABSTRACT A LC-MS/MS method was validated for the simultaneous quantification of 4 quinolones (oxolinic acid, enrofloxacine, ciprofloxacine, norfloxacine) and 4 sulfonamides (sulfamethoxypyridazine, sulfadoxine, sulfadimidine, sulfamerazine) on fish muscle following the Euro- pean Union’s (EU) criteria for the analysis of veterinary drug residues in foods. One gram of sample was extracted by acidic acetonitrile (0.5 mL of 0.1% formic acid in 7 mL of ACN), followed by LC-MS/MS analysis using an electrospray ionization interface. Typical recoveries of the 4 quinolones in the fish tissues ranged from 85 to 104%. While those of the sulfonamides ranged from 75 to 94% at the fortification level of 5.0 μg/kg. The decision limits (CCα) and detection capabilities (CCβ) of the quinolones were 1.35 to 2.10 μg/kg and 1.67 to 2.75 μg/kg, respectively. Meanwhile, the CCα and CCβ of the sulfonamides ranged from 1.62 μg/kg to 2.53μg/kg and 2.01μg/kg to 3.13 μg/kg, respectively. -
