REVIEW
Sherif Hanafy Mahmoud, Chen Shen
Augmented renal clearance (ARC) is a manifestation of enhanced renal function seen in critically ill patients. The use of regular unadjusted doses of renally eliminated drugs in patients with ARC might lead to therapy failure. The purpose of this scoping review was to provide and up-to-date summary of the available evidence pertaining to the phenomenon of ARC. A literature search of databases of available evidence in humans, with no language restriction, was conducted. Databases searched were MEDLINE (1946 to April 2017), EMBASE (1974 to April 2017) and the Cochrane Library (1999 to April 2017)...

OBJECTIVES: This preliminary study aimed to determine whether augmented renal clearance (ARC) impacts negatively on the clinical outcome in traumatic brain-injured patients (TBI) treated for a first episode of ventilator-acquired pneumonia (VAP). METHODS: During a 5-year period, all TBI patients who had developed VAP were retrospectively reviewed to assess variables associated with clinical failure in multivariate analysis. Clinical failure was defined as an impaired clinical response with a need for escalating antibiotics during treatment and/or within 15 days after the end-of-treatment...

Pediatric dialysis patients are at risk of nutritional illness secondary to deficiencies in water-soluble vitamins and trace elements. Unlike 25-OH vitamin D, most other vitamins and trace elements are not routinely monitored in the blood and, consequently, the detection of any deficiency may not occur until significant complications develop. Causes of vitamin and trace element deficiency in patients on maintenance dialysis patient are multifactorial, ranging from diminished nutritional intake to altered metabolism as well as dialysate-driven losses of water-soluble vitamins and select trace elements...

AIMS: Measured glomerular filtration rate (mGFR) is often used to identify augmented renal clearance (ARC). However, in the clinical setting, estimated GFR (eGFR) is obtained more quickly and inexpensively. We aimed to determine whether eGFR can identify ARC by evaluating the correlation between the eGFR and vancomycin trough level (VTL). MATERIALS AND METHODS: We retrospectively reviewed the records of patients aged ≤ 18 years who underwent vancomycin therapeutic drug monitoring at our tertiary hospital from July 2009 to June 2014...

Endothelin-1 (ET-1) is involved in the pathogenesis of cardiac and renal diseases, and in the progression of tumour growth in cancer, but current diagnosis and treatment remain inadequate. Peptides derived from the 212 amino acid precursor preproendothelin-1 (ppET-1) may have utility as biomarkers, or cause biological effects that are unaffected by endothelin receptor antagonists. Here, we used specific immunoassays and LC-MS/MS to identify NT-proET-1 (ppET-1[18-50]), Endothelin-Like Domain Peptide (ELDP, ppET-1[93-166]) and CT-proET-1 (ppET-1[169-212]) in conditioned media from cultured endothelial cells...

BACKGROUND: Appropriate utilization of vancomycin is important to attain therapeutic targets while avoiding clinical failure and the development of antimicrobial resistance. Our aim was to observe the use of vancomycin in an intensive care population, with the main focus on achievement of therapeutic serum concentrations (15-20 mg/l) and to evaluate how this was influenced by dose regimens, use of guidelines and therapeutic drug monitoring. METHODS: A prospective observational study was carried out in the intensive care units at two tertiary hospitals in Norway...

In mammals, insulin primarily lowers plasma glucose (PGlu) by increasing its uptake into tissues. Studies have also shown that insulin lowers PGlu in mammals by modulating glomerular filtration rate (GFR). Birds have naturally high PGlu and, although insulin administration significantly decreases glucose concentrations, birds are resistant to insulin-mediated glucose uptake into tissues. Since prior work has not examined the effects of insulin on GFR in birds, the purpose of the present study was to assess whether insulin can augment renal glucose excretion and thereby lower PGlu...

Augmented renal clearance (ARC) is known to influence β-lactam antibiotic pharmacokinetics. This substudy of the BLING-II trial aimed to explore the association between ARC and patient outcomes in a large randomised clinical trial. BLING-II enrolled 432 participants with severe sepsis randomised to receive β-lactam therapy by continuous or intermittent infusion. An 8-h creatinine clearance (CLCr) measured on Day 1 was used to identify ARC, defined as CLCr ≥ 130 mL/min. Patients receiving any form of renal replacement therapy were excluded...

Critically ill patients frequently have substantially altered pharmacokinetics compared to non-critically ill patients. We investigated the impact of pharmacokinetic alterations on bacterial killing and resistance for commonly used meropenem dosing regimens. A Pseudomonas aeruginosa isolate (MICmeropenem 0.25 mg/liter) was studied in the hollow-fiber infection model (inoculum ∼10(7.5) CFU/ml; 10 days). Pharmacokinetic profiles representing critically ill patients with augmented renal clearance (ARC), normal, or impaired renal function (creatinine clearances of 285, 120, or ∼10 ml/min, respectively) were generated for three meropenem regimens (2, 1, and 0...

We investigated the population pharmacokinetics (PK) of doripenem in Korean patients with acute infections and determined an appropriate dosing regimen using a Monte Carlo simulation for predicting pharmacodynamics (PD). Patients (n = 37) with a creatinine clearance (CLCR) of 20 to 50 ml/min or >50 ml/min who received a 250-mg or 500-mg dose of doripenem over the course of 1 h every 8 h, respectively, were included in this study. Blood samples were taken predosing and 0 h, 0.5 h, and 4 to 6 h after the fourth infusion...

BACKGROUND: Augmented renal clearance (ARC) is common in trauma patients and associated with subtherapeutic antimicrobial concentrations. This study reported the incidence of ARC, identified ARC risk factors, and described a model to predict ARC (i.e., ARCTIC) that is specific to trauma patients. METHODS: Consecutive trauma patients who were admitted to the intensive care unit between March 2015 and January 2016 and had a measured creatinine clearance (CrCl) were considered for inclusion...

Collectrin, encoded by the Tmem27 gene, is a transmembrane glycoprotein with approximately 50% homology with angiotensin converting enzyme 2, but without a catalytic domain. Collectrin is most abundantly expressed in the kidney proximal tubule and collecting duct epithelia, where it has an important role in amino acid transport. Collectrin is also expressed in endothelial cells throughout the vasculature, where it regulates L-arginine uptake. We previously reported that global deletion of collectrin leads to endothelial dysfunction, augmented salt sensitivity, and hypertension...

INTRODUCTION: Ceftolozane/tazobactam is an antibacterial agent with potent in vitro activity against Gram-negative pathogens, including many extended-spectrum β-lactamase-producing Enterobacteriaceae and drug-resistant Pseudomonas aeruginosa. Because ceftolozane/tazobactam is primarily excreted renally, appropriate dose adjustments are needed for patients with renal impairment. Monte Carlo simulations were used to determine the probability of pharmacokinetic/pharmacodynamic target attainment for patients with varying degrees of renal function, including augmented renal clearance (ARC) and end-stage renal disease (ESRD) with hemodialysis...

 The efficacy of cefepime (CFPM) is known to depend on the ratio of the time that the serum levels exceed the minimum inhibitory concentration (MIC) to the dosing interval (%T>MIC). The objective of this study was to clarify the relation between %T>MIC and clinical outcome of CFPM, and to identify the optimal dosage regimen. We investigated the outcome of CFPM treatment for febrile neutropenia (FN) patients with normal renal function. Treatment success was defined as the completion of FN therapy with CFPM only...

Currently there are no pharmacokinetic (PK) data to guide antibiotic dosing in critically ill Australian Indigenous patients with severe sepsis. This study aimed to determine whether the population pharmacokinetics of meropenem were different between critically ill Australian Indigenous and critically ill Caucasian patients. Serial plasma and urine samples as well as clinical and demographic data were collected over two dosing intervals from critically ill Australian Indigenous patients. Plasma meropenem concentrations were assayed by validated chromatography...
