Abstract
Amikacin sulfate-loaded dextran sulfate sodium nanoparticles were formulated, lyophilized (LADNP), and then analyzed. The LADNP had a −20.9 ± 8.35 mV zeta potential, PDI of 0.256, and % PDI of 67.7. The zeta average nano size of LADNP was 317.9 z. d.nm, while the dimension of an individual particle was 259.3 ± 73.52 nm, and nanoparticle conductivity in colloidal solution was 2.36 mS/cm. LADNP has distinct endothermic peaks at temperatures at 165.77 °C, according to differential scanning calorimetry (DSC). The thermogravimetric analysis (TGA) showed the weight loss of LADNP, which was observed as 95% at 210.78 °C. XRD investigation on LADNP exhibited distinct peaks at 2θ as 9.6°, 10.4°, 11.4°, 18.9°, 20.3°, 24.4°, 28.2°, 33.2°, 38.9°, and 40.4° confirming crystalline structure. The amikacin release kinetics from LADNP revealed zero order kinetics with a linear release showed zero order kinetics with 37% of drug release in 7 h and had an R2 value of 0.99. The antibacterial effect of LADNP showed broad-spectrum activity against tested human pathogenic bacteria. The preset study demonstrated that LADNP is a promising antibacterial agent.

Antibiotic use evaluation in hospitalized pediatric patients with respiratory tract infections: A retrospective chart review study. Curr Drug Saf 2021; 17:17-23. [PMID: 33602106 DOI: 10.2174/1574886316666210218104644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 01/07/2021] [Accepted: 01/09/2021] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Respiratory tract infections (RTIs) are a common cause of antibiotic usage in hospitalized pediatric patients. Inappropriate use of antibiotics may lead to the emergence of multidrug-resistant microorganisms and increased treatment costs. OBJECTIVE This study was designed to assess antibiotic usage in hospitalized pediatric patients with RTIs. METHODS Medical charts of the patients admitted to the pediatric ward (PW) and pediatric intensive care unit (PICU) of a tertiary respiratory center were reviewed. Patients' demographic and clinical data including gender, age, weight, history of allergy, length of hospital stay, clinical diagnosis, prescribed antibiotics (indication, dose, and frequency of administration) were collected. The appropriateness of antibiotic usage was evaluated in each patient according to international guidelines. RESULTS Two hundred seventy-nine hospitalized patients were included in the study. The most common reason for hospitalization was pneumonia (38%), followed by cystic fibrosis (20.1%) and bronchitis (5%). The most commonly used antimicrobial agents were ceftriaxone, azithromycin, and clindamycin which guideline adherence for their usage was 85.3%, 23.3%, and 47%; respectively. Inappropriate dose selection was the main reason for non-adherence to the guidelines. The adherence rate to RTIs' guidelines (considering all parameters for each patient) was 27.6%. Multivariate logistic regression analysis demonstrated CF and prescription of azithromycin are predictors of guideline non-adherence. CONCLUSION We found relatively low adherence to international guidelines in our center that could be related to restricted definitions of optimal antibiotic therapy. Despite most patients received logical antimicrobial therapy, actions should be taken into account to reach optimal antibiotic usage.

Abstract
BACKGROUND Estimating kidney function is essential to consider in drug dosing for renally eliminated drugs. It has been estimated that more than half of medications' adverse effects are caused by the inappropriate dosing. Limited data are available on drug dosing adjustment, particularly the antibiotics, among Jordanian patients with declined kidney function. AIM The aim of this study was to evaluate the extent of antibiotics' dose adjustment according to the recent guidelines of drugs' renal dose adjustment. METHOD The present study utilised data from a previous retrospective study, which recruited inpatients who were clinically stable and received IV antibiotics for more than 24 hours at King Abdullah University Hospital. Sociodemographic and clinical data were collected by referring to information technology departments at KAUH. The percentage of antibiotics which were inappropriately adjusted based on creatinine clearance was evaluated using Lexicomp-Clinical Drug information website. RESULTS A total of 110 antibiotics were dispensed for 80 patients. Results showed that (36.25%) of patients were given antibiotics without renal dose adjustments based on their creatinine clearance. Urinary tract infections followed by respiratory tract infections were the most common among the study participants. The most commonly prescribed antibiotic was Imipenem/cilastatin (41.25%). Among antibiotics prescribed without renal dose adjustment, Imipenem/cilastatin was the most common and represented 62% of the cases while vancomycin was the least and represented only 3.45% of the non-renally adjusted doses. CONCLUSIONS The current study clearly demonstrates the lack of adherence to recent guidelines of renal dose adjustment for renally excreted antibiotics. Such findings shed the light on the necessity of considering antibiotics dose adjustment in patients with declined kidney function with the aim of ensuring medication safety and improve health outcomes.

Abstract
Currently used creatinine-based parameters for monitoring kidney function are not reliable for early detection of kidney injury (KI), particularly tubular damage. Several KI biomarkers allow for early detection of glomerular and tubular damage and may help to prevent drug-related chronic kidney diseases in pediatrics. This literature review describes the state of current research and investigates reference values for these KI biomarkers in neonates, infants, and children to better understand age-related changes. A total of 12 of 237 screened studies fulfilled predefined criteria, including 219 preterm neonates, 70 neonates, 596 infants, and 1726 children. KI biomarkers were analyzed in urine (6 studies), in serum/plasma (5 studies) and in serum and urine (1 study). Four studies (n = 555) measured urinary kidney injury molecule-1, whereas urinary neutrophil gelatinase-associated lipocalin was assessed in 5 studies (n = 888), and 2 studies (n = 203) investigated serum cystatin C. This review of KI biomarkers in different pediatric age groups indicates that (1) the majority of KI biomarkers are measured in urine; (2) the 3 most commonly analyzed KI biomarkers are urinary neutrophil gelatinase-associated lipocalin, urinary kidney injury molecule-1, and serum cystatin C; (3) values of KI biomarkers appear to decrease from prematurity to infancy; and (4) there is an unmet need to further enhance knowledge on age-dependent changes of KI biomarkers in pediatrics. Studies are needed to better characterize reference values for these key KI biomarkers in healthy pediatric populations and to evaluate the value of these markers in the early detection of drug-related KI in neonates, infants, and children.

Abstract
Plazomicin is an FDA-approved aminoglycoside for the treatment of complicated urinary tract infections. In this open-label study, 24 adults with normal renal function or mild, moderate, or severe renal impairment (n = 6 per group) received a single 7.5-mg/kg of body weight dose of plazomicin as a 30-min intravenous infusion. Total clearance declined with renal impairment, resulting in 1.98-fold and 4.42-fold higher plazomicin exposures, as measured by the area under the concentration-time curve from 0 h to infinity, in subjects with moderate and severe impairment, respectively, than in subjects with normal renal function. (This study has been registered at ClinicalTrials.gov under identifier NCT01462136.).

Abstract
Aminoglycoside antibiotics (AGAs) were developed at the dawn of the antibiotics era and have significantly aided in the treatment of infectious diseases. Aminoglycosides have become one of the four major types of antibiotics in use today and, fortunately, still have an important role in the clinical treatment of severe bacterial infections. In this review, the current usage, modes of action and side effects of AGAs, along with the most common bacterial resistance mechanisms, are outlined. Finally, the recent development situation and possibility of new AGAs in the 'post-antibiotic era' are considered.The Journal of Antibiotics advance online publication, 25 October 2017; doi:10.1038/ja.2017.117.

Gentamicin in hemodialyzed critical care patients: early dialysis after administration of a high dose should be considered. Antimicrob Agents Chemother 2012; 57:977-82.

Abstract
Gentamicin is a widely used antibiotic in the intensive care unit (ICU). Its dosage is difficult to adapt to hemodialyzed ICU patients. The FDA-approved regimen consists of the administration of 1 to 1.7 mg/kg of gentamicin at the end of each dialysis session. Better pharmacokinetic management could be obtained if gentamicin were administered just before the dialysis session. We performed Monte Carlo simulations (MCS) to determine the best gentamicin pharmacokinetic profile (high peak and low trough concentrations). Then, 6 mg/kg of gentamicin was infused into 10 ICU patients over a period of 30 min. A 4-h-long hemodialysis session was started 30 min after the end of the infusion. Pharmacokinetic samples were regularly collected over 24 h. A one-compartment model with zero-order input and first-order elimination was developed in Nonmem version VI to analyze patients' measured gentamicin concentration-versus-time profiles. Finally, additional MCS were performed to compare the regimen chosen with the FDA-approved gentamicin regimen. High peak concentrations (C(max), 31.8 ± 16.8 mg/liter) were achieved. The estimated C(24) and C(48) values (concentrations 24 and 48 h, respectively, after the beginning of the infusion) were 4.1 ± 2.3 and 1.8 ± 1.2 mg/liter, respectively. The volume of distribution was 0.21 ± 0.06 liter/kg. MCS confirmed that the dosing regimen chosen achieved the target C(max) whereas the FDA-approved regimen did not (31.0 ± 10.9 versus 8.8 ± 3.1 mg · liter(-1)). Moreover, the C(24) values were similar while the AUC(0-24) values were moderately increased (190.8 ± 65.0 versus 135 ± 42.2 mg · h · liter(-1)). Therefore, administration of 6 mg/kg of gentamicin before hemodialysis to critically ill patients achieves a high C(max) and an acceptable AUC, maximizing pharmacokinetic/pharmacodynamic endpoints.
