Gentamicin is an aminoglycoside antibiotic widely used to treat many types of bacterial infections. Although its properties, his clinical use is limited due to the occurrence of nephrotoxicity, which has been related to mitochondrial dysfunction. Carvedilol, an antihypertensive drug with strong antioxidant properties, has been tested in order to prevent gentamicin nephrotoxicity. This study aimed to test this hypothesis using a rat model of gentamicin-induced nephrotoxicity. Animals were treated subcutaneously with DMSO (control) (0...

Hematopoietic stem cell transplantation (HSCT) is a highly effective treatment strategy for lymphoproliferative disorders and bone marrow failure states including aplastic anemia and thalassemia. However, its use has been limited by the increased treatment related complications, including acute kidney injury (AKI) with an incidence ranging from 20% to 73%. AKI after HSCT has been associated with an increased risk of mortality. The incidence of AKI reported in recipients of myeloablative allogeneic transplant is considerably higher in comparison to other subclasses mainly due to use of cyclosporine and development of graft-versus-host disease (GVHD) in allogeneic groups...

Aminoglycoside antibiotics, in particular gentamicin and tobramycin, are still commonly used in paediatric clinical practice. These drugs cause nephrotoxicity, which particularly affects the proximal tubule epithelial cells due to selective endocytosis and accumulation of aminoglycosides via the multi-ligand receptor megalin. Recent epidemiological studies, using more widely accepted definitions of acute kidney injury (AKI), have suggested that AKI may occur in between 20 and 33 % of children exposed to aminoglycosides...

BACKGROUND: Serum cystatin C (CysC) is a more accurate glomerular filtration rate marker than serum creatinine (SCr) and may rise more quickly with acute kidney injury (AKI). METHODS: We performed a prospective cohort study of 81 non-critically ill children during 110 aminoglycoside (AG) treatments. We calculated area under the curve (AUC) for CysC to diagnose SCr-defined AKI and predict persistent AKI. SCr-AKI definition was based on the Kidney Disease: Improving Global Outcomes (≥stage 1: ≥50 % or 26...

Gentamicin is a commonly used aminoglycoside antibiotic. However, its therapeutic use is limited by its nephrotoxicity. The mechanisms of gentamicin-induced nephrotoxicity are principally from renal inflammation and oxidative stress. Since atorvastatin, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, exerts lipid-lowering effects, antioxidant, anti-inflammatory as well as anti-apoptotic effects, this study aimed to investigate the protective effects of atorvastatin against gentamicin-induced nephrotoxicity...

BACKGROUND: Gentamicin is an aminoglycoside antibiotic widely used in the treatment of infections caused by Gram-negative bacteria. The main limitation to its therapeutic effectiveness is the potential nephrotoxicity. Erythropoietin has a tissue protective effect widely demonstrated in the kidney. The aim of the present study was to evaluate the renoprotective effects of erythropoietin in a model of zebrafish (Danio rerio) after administration of gentamicin. METHODS: Sixty adult zebrafish were subdivided into three groups: group A was treated with gentamicin; group B received gentamicin and, 24 h later, epoetin alpha; group C received drug diluent only...

AIMS: The kidney disease improving global outcomes (KDIGO) clinical practice guidelines for acute kidney injury (AKI) has endorsed the widely held belief that female gender is a risk factor for aminoglycoside-associated nephrotoxicity (AAN). In contrast, female gender is protective in animal models. In light of this dichotomy, we sought to explore this relationship in greater detail. METHODS: We performed a meta-analysis of studies published between 1978 and 2015 which examined aminoglycoside nephrotoxicity and provided gender-specific data...

Escherichia coli NB8 is a clinical pyelonephritis isolate. Here, we report the draft genome sequence of uropathogenic E. coli NB8, which contains drug resistance genes encoding resistance to beta-lactams, aminoglycosides, quinolones, macrolides, colistin, sulfonamide-trimethoprim, and tetracycline. NB8 infects the kidney and bladder, making it an important tool for studying E. coli pathogenesis.

BACKGROUND: Data on antimicrobial prophylaxis for open fractures is limited, with many protocols based on expert recommendations. These protocols include aminoglycosides (AGs) for fractures with significant soft tissue injury, but these drugs are associated with acute kidney injury (AKI) in other settings; this risk has not been defined for open fracture prophylaxis. METHODS: We performed a retrospective study from May 2012 to October 2014 at our Level 1 trauma center...

OBJECTIVES: Multiresistant Gram-negative pathogens pose major healthcare concerns with a limited therapeutic armamentarium. Aminoglycosides (AG) are under-utilized due to nephrotoxicity. We aimed to evaluate AG-associated acute kidney injury (AG-AKI) in elderly inpatients, with and without shock. METHODS: We examined the incidence and predictors of AG-AKI by KDIGO criteria and extended renal dysfunction (ERD) in patients aged >60 years. ERD represented a composite of hospital mortality or absence of renal recovery over 6 months following AG-AKI...

OBJECTIVE: Therapeutic drug monitoring (TDM) enables individualization in the treatment to optimize clinical benefit and minimize drugs' side effects. Critically ill septic patients represent a challenge for antimicrobial treatment because of pathophysiological impact of sepsis on pharmacokinetics of drugs. The aim of this study was to assess the appropriateness of gentamicin and amikacin dosing in critically and noncritically ill patients, as well as to estimate the need for its regular therapeutic monitoring...

Exposure to nephrotoxic medication is among the most common causes of acute kidney injury (AKI) in hospitalized patients. Here we conducted a prospective quality improvement project implementing a systematic Electronic Health Record screening and decision support process (trigger) in our quaternary pediatric inpatient hospital. Eligible patients were noncritically ill hospitalized children receiving an intravenous aminoglycoside for more than 3 days or more than 3 nephrotoxins simultaneously (exposure) from September 2011 through March 2015...

Residual kidney function (RKF) may confer a variety of benefits to patients on maintenance dialysis. RKF provides continuous clearance of middle molecules and protein-bound solutes. Whereas the definition of RKF varies across studies, interdialytic urine volume may emerge as a pragmatic alternative to more cumbersome calculations. RKF preservation is associated with better patient outcomes including survival and quality of life and is a clinical parameter and research focus in peritoneal dialysis. We propose the following practical considerations to preserve RKF, especially in newly transitioned (incident) hemodialysis patients: (1) periodic monitoring of RKF in hemodialysis patients through urine volume and including residual urea clearance with dialysis adequacy and outcome markers such as anemia, fluid gains, minerals and electrolytes, nutritional, status and quality of life; (2) avoidance of nephrotoxic agents such as radiocontrast dye, nonsteroidal anti-inflammatory drugs, and aminoglycosides; (3) more rigorous hypertension control and minimizing intradialytic hypotensive episodes; (4) individualizing the initial dialysis prescription with consideration of an incremental/infrequent approach to hemodialysis initiation (e...

Aminoglycosides are very effective antibiotics for the treatment of severe infections, but they rank among the most frequent causes of drug-induced nephrotoxicity. Thus, prevention of aminoglycoside nephrotoxicity is an unmet therapeutic objective. Cardiotrophin-1 (CT-1), a member of the IL-6 family of cytokines, has been reported to protect the kidney against toxic and ischemic acute kidney injury (AKI). We have assessed the effect of rat CT-1 in the severity of gentamicin (G)-induced AKI. Groups of male Wistar rats received the following for 6 consecutive days: i) isotonic saline solution (group CONT), ii) G, 150mg/kg/day, i...

INTRODUCTION: Aminoglycosides (AG) cause nephrotoxicity in 10 - 20% of patients. One of the mechanisms is by generating reactive oxygen species (ROS), leading to DNA destruction and activation of poly(ADPribose) polymerase (PARP) causing necrotic tubular cell death. PARP inhibition on gentamicin-induced nephrotoxicity was studied. METHODS: 19 female Wistar-Kyoto rats divided into 3 groups: control (3 rats receiving no treatment); gentamicin-treated group (8 rats); and 8 rats treated with gentamicin combined with 3-aminobenzamide (3 AB)...

OBJECTIVE: To evaluate the association between caffeine exposure and acute kidney injury (AKI) in very low birth weight (VLBW; ≤1500 g) neonates. STUDY DESIGN: We retrospectively reviewed a cohort of 140 VLBW neonates consecutively admitted to the University of Virginia's neonatal intensive care unit from March 2011 to June 2012, excluding only those admitted >2 days of age or who died at <2 days after birth. We separately analyzed a subgroup of 44 neonates who received prolonged invasive respiratory support (mechanical ventilation for first 7 days after birth)...
