Background: Patients with cystic fibrosis (CF) are at risk of kidney injury even before undergoing lung transplantation, because of prolonged exposure to aminoglycosides (AGs), chronic dehydration and complications of diabetes mellitus. The usual equations estimating the glomerular filtration rate (GFR), such as Cockcroft-Gault and Modification of Diet in Renal Disease, are not adapted to the CF population due to patients' low body weight and reduced muscle mass. The aim of this study was to precisely measure GFR in adult CF patients and to see whether repeated AG treatment would impair renal function before lung transplantation...

Gentamicin (GM) is an aminoglycoside antibiotic used in treatment of various types of bacterial infections, but the major adverse effect is drug-induced nephrotoxicity. This study aimed to determine biomarkers that might predict nephrotoxicity initiated by GM using serum or urinary proton nuclear magnetic resonance (1 H NMR) spectral data in male Sprague-Dawley rats. GM (0, 30, or 300 mg/kg/d) was intraperitoneally administered for 3 consecutive days. Animals were sacrificed 2 d (D2) or 8 d (D8) after last administration of GM in order to perform analysis of serum biochemistries and histopathologic examination...

Vancomycin, discovered in 1953 and widely used today, has a nephrotoxic potential that has long been debated. The frequency of renal involvement is variable and can range from 5% to 30% depending concomitant risk factors: overdose, chronic kidney disease, obesity, hypovolemia, and use of other nephrotoxic drugs as aminoglycosides. Its association with piperacillin-tazobactam also appears to increase the risk of nephrotoxicity. This hypothesis should be confirmed experimentally. Vancomycin-induced oxidative stress in tubular cells and intraluminal cast formation are the two physiopathological mechanisms explaining its nephrotoxicity...

Aminoglycosides are commonly used for the treatment of pulmonary exacerbations in patients with cystic fibrosis (CF). However, they are potentially nephrotoxic. This prospective observational cohort study aimed to investigate the potential validity of two urinary renal biomarkers, Kidney Injury Molecule-1 (KIM-1) and Neutrophil Gelatinase-associated Lipocalin (NGAL), in identifying aminoglycoside-induced nephrotoxicity in children with CF. Children and young adults up to 20 years of age with a confirmed diagnosis of CF were recruited from ten United Kingdom hospitals...

Background: Brucellosis is a bacterial infection, caused by the nonmotile gram-negative aerobic coccobacilli. The clinical manifestation of brucellosis is variable, ranging from mild disease to severe disease. The gold standard test to confirm the diagnosis of brucellosis is assaying blood, bone marrow, or other body fluids or by tissue culture. Preferred first-line treatment in adults with uncomplicated, nonlocalized disease consists of doxycycline-aminoglycoside combination. The recommended duration of treatment is 6 weeks...

BACKGROUND AND OBJECTIVE: Gram-negative bacilli are the causative organisms for a significant proportion of patients with severe community acquired pneumonia (CAP) admitted to the intensive care unit (ICU). Clinical guidelines recommend broad spectrum antimicrobials for empiric treatment despite alarming global trends in antimicrobial resistance. We aimed to assess the safety and efficacy of gentamicin, an aminoglycoside with potent bactericidal activity, for empiric Gram-negative cover of severe CAP admitted to ICU...

To overcome serious methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa infections, we synthesized TS2037, 5,4″-diepi-arbekacin, a novel aminoglycoside antibiotic, and evaluated its biological properties. TS2037 showed broad-range, as well as robust antibacterial activities against Gram-positive and Gram-negative bacteria. The MIC50 and MIC90 of TS2037 against clinical isolates of MRSA (n = 54) were both 0.25 µg/mL, and no resistant strain was observed. The MIC50 and MIC90 of TS2037 against clinical isolates of P...

PURPOSE: Infectious complications in open lower extremity fractures contribute to significant morbidity. Historically, orthopedic guidelines have recommended Grade III fractures receive a first generation cephalosporin and an aminoglycoside. Despite these guidelines, few studies have evaluated the utility of adding an aminoglycoside in this patient population. At our trauma center, we have a unique trauma service where half of our surgeons treat Grade III open fractures with a cephalosporin alone and half use a cephalosporin + aminoglycoside...

REVIEW

Aminoglycoside antibiotics remain widely used for urgent clinical treatment of life-threatening infections, despite the well-recognized risk of permanent hearing loss, i.e., cochleotoxicity. Recent studies show that aminoglycoside-induced cochleotoxicity is exacerbated by bacteriogenic-induced inflammation. This implies that those with severe bacterial infections (that induce systemic inflammation), and are treated with bactericidal aminoglycosides are at greater risk of drug-induced hearing loss than previously recognized...

Background: A sex difference in cisplatin-induced nephrotoxicity (CIN) has been reported in human and animal studies. We examined in humans whether it is associated with sex-hormone changes. Methods: In this retrospective nationwide cohort study, we used Taiwan's National Health Insurance Research Database (NHIRD) to identify patients with a history of malignancy and cisplatin treatment. Patients diagnosed with kidney disease before cisplatin treatment and those with sex-organ malignancies were excluded. A diagnosis of kidney disease within 90 days after the first administration of cisplatin was the study outcome...

BACKGROUND: With improved prognosis of CF, comorbidities including chronic kidney disease (CKD) are becoming increasingly important. Identification of those at highest CKD risk is hence a priority. METHODS: In this cross-sectional study, adults with CF attending the Copenhagen CF Centre at Rigshospitalet with ≥2 measurements of serum creatinine from 2013 to 2015 were included. Data was obtained from an electronic CF database, which contains anonymised clinical and laboratory data on all individuals attending the clinic...

A retrospective cohort study, were evaluated: polymyxin B plus aminoglycosides or polymyxin B plus other antibiotics. Any degree of acute kidney injury occurred in 26 (86.6%) patients. The median time to acute kidney injury was 6.0 (95% CI 3-14) days in the polymyxin-aminoglycoside containing regimen group, against 27.0 (95% CI 6-42) days in the polymyxin with other antimicrobial combinations group (p=0.03). Polymyxin B with aminoglycosides group progressed faster to any degree of renal dysfunction.

The way to maximize scope of analysis, sample throughput, and laboratory efficiency in the monitoring of veterinary drug residues in food animals is to determine as many analytes as possible as fast as possible in as few methods as possible. Capital and overhead expenses are also reduced by using fewer instruments in the overall monitoring scheme. Traditionally, the highly polar aminoglycoside antibiotics require different chromatographic conditions from other classes of drugs, but in this work, we demonstrate that an ion-pairing reagent (sodium 1-heptanesulfonate) added to the combined final extracts from two sample preparation methods attains good separation of 174 targeted drugs, including 9 aminoglycosides, in the same 10...

Aminoglycoside antibiotics are used as prophylaxis, or urgent treatment, for many life-threatening bacterial infections, including tuberculosis, sepsis, respiratory infections in cystic fibrosis, complex urinary tract infections and endocarditis. Although aminoglycosides are clinically-essential antibiotics, the mechanisms underlying their selective toxicity to the kidney and inner ear continue to be unraveled despite more than 70 years of investigation. The following mechanisms each contribute to aminoglycoside-induced toxicity after systemic administration: (1) drug trafficking across endothelial and epithelial barrier layers; (2) sensory cell uptake of these drugs; and (3) disruption of intracellular physiological pathways...

Etimicin (ETM), which belongs to the newest generation of aminoglycosides (AGs), has been proven to not only maintain but also strengthen the advantages of former AGs with relatively less toxicity. Now, it is widely applied for the treatment of bacterial infections in the clinic. Nevertheless, nephrotoxicity and ototoxicity are unavoidable issues for AGs, and while ETM is no exception, the seriousness of these issues is different. To explore the reason why ETM exhibits less toxicity and to better direct the optimization and development of new AGs, it is of great necessity and importance to monitor the pharmacokinetic behaviors of ETM in its potential toxicity target organs, the kidney and internal ear, as well as in plasma...

Acute kidney injury (AKI) is an important health problem and can be caused by number of factors. The use of aminoglycosides, such as gentamicin, is one of these factors. Recently, an effort has been made to find biomarkers to guide treatment protocols. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used to estimate the contents of Ca, Cu, Fe, K, Mg, Mn, Na, P, and Zn in serum and urine of the healthy, AKI, and spontaneous recovery (SR) groups of animals. The animal model of AKI and SR was validated by measuring serum and urinary urea and creatinine...

The current standard of care for prosthetic joint infection includes two-stage arthroplasty, with antibiotic-impregnated cement spacers (ACS) utilized between the stages. We report a 75-year-old woman with previously normal renal function, who developed acute kidney injury (AKI) secondary to biopsy-proven acute tubular necrosis and acute interstitial nephritis after ACS placement containing tobramycin and vancomycin. Peak tobramycin level measured 25.3 mcg/mL, the highest value reported in the literature after ACS placement...
