Blood pressure control with renin-angiotensin system (RAS) blockade has remained the gold standard for treating patients with proteinuric chronic kidney disease (CKD) up to date. Nevertheless, RAS blockade slows but does not halt the progression of kidney disease, thus highlighting the need to search for additional therapeutic approaches. The nonselective phosphodiesterase (PDE) inhibitor pentoxifylline (PTX) is an old drug that exhibits prominent anti-inflammatory, anti-proliferative and anti-fibrotic activities both in vitro and in vivo...

BACKGROUND: Cefiderocol is a siderophore cephalosporin that displays potent in vitro activity against multi-drug resistant (MDR) Gram-negative bacteria. We aimed to describe cefiderocol's pharmacokinetics, pharmacodynamics, and 24-hour efficacy using dose-ranging methods in the neutropenic murine thigh infection model. METHODS: Infection was established in neutropenic mice (administered cyclophosphamide 150 mg/kg and 100 mg/kg 4 and 1 days prior to inoculation respectively) with 8 Pseudomonas aeruginosa isolates (MIC range: 0...

The kidney is an organ that plays a major role in the excretion of numerous compounds such as drugs and chemicals. However, a great number of pharmacological molecules are nephrotoxic, affecting the efficiency of the treatment and increasing morbidity or mortality. Focusing on glomerular filtration, we propose in this study a simple and reproducible in vitro human model that is able to bring to light a functional podocyte injury, correlated with morphologic/phenotypic changes after drug exposure. This model was used for the evaluation of paracellular permeability of FITC-dextran molecules as well as FITC-BSA after different treatments...

Dual antiplatelet agents and high-intensity statins are frequently used in combination after myocardial infarction. Ticagrelor has the potential of causing acute kidney injury. Rosuvastatin is excreted through the kidneys and dose adjustment is needed in patients with kidney disease. When used in combination, they can potentiate the toxic effects of each other. We report a case of drug interaction between rosuvastatin and ticagrelor resulting in rhabdomyolysis and acute renal failure necessitating dialysis...

BACKGROUND: Among adolescents with type 1 diabetes, rapid increases in albumin excretion during puberty precede the development of microalbuminuria and macroalbuminuria, long-term risk factors for renal and cardiovascular disease. We hypothesized that adolescents with high levels of albumin excretion might benefit from angiotensin-converting-enzyme (ACE) inhibitors and statins, drugs that have not been fully evaluated in adolescents. METHODS: We screened 4407 adolescents with type 1 diabetes between the ages of 10 and 16 years of age and identified 1287 with values in the upper third of the albumin-to-creatinine ratios; 443 were randomly assigned in a placebo-controlled trial of an ACE inhibitor and a statin with the use of a 2-by-2 factorial design minimizing differences in baseline characteristics such as age, sex, and duration of diabetes...

BACKGROUND: The association of metabolic syndrome (MetS) traits with urinary calcium (UCE) or oxalate excretion (UOE) is uncertain in calcium stone formers (CSFs). Our aim was to investigate this association in a large group of Caucasian CSFs. METHODS: We retrospectively reviewed data of CSFs evaluated at our Kidney Stone Clinic from 1984 to 2015. Data on body mass index (BMI), MetS traits defined according to international consensus, family history of urolithiasis, anti-hypertensive treatments, calcemia, renal function, and 24-h urinary profile of lithogenic risk were collected...

Diabetic nephropathy is one of the most important microvascular complications of diabetes mellitus and is responsible for 40-50% of all cases of end stage renal disease. The therapeutic strategies in diabetic nephropathy need to be targeted towards the pathophysiology of the disease. The earlier these therapeutic strategies can bring about positive effects on vascular changes and prevent the vasculature in patients with diabetes from deteriorating, the better the renal function can be preserved. Studies evaluating anti-inflammatory and antioxidative strategies in diabetic nephropathy demonstrate the need and value of these novel treatment avenues...

Cerebral edema remains a significant cause of morbidity and mortality in patients with acute liver failure (ALF) and has been linked to elevated blood ammonia levels. L-ornithine phenylacetate (OPA) may decrease ammonia by promoting its renal excretion as phenylacetylglutamine (PAGN), decreasing the risk of cerebral edema. We evaluated the safety, tolerability, and pharmacokinetics of OPA in patients with ALF and acute liver injury (ALI), including those with renal failure. Forty-seven patients with ALI/ALF and ammonia ≥60µM were enrolled...

Berberine, a well-known plant alkaloid derived from Rhizoma coptidis, has potential applications as a therapeutic drug for diabetic nephropathy. However, the transporter-mediated renal transport of berberine remains largely unclear. This study aimed to investigate the renal transport mechanism of berberine using transfected cells, kidney slices, and animal experiments. In Madin-Darby canine kidney (MDCK) cells stably expressing rat OCT2 (MDCK-rOCT2) and kidney slices, saturable and non-saturable uptake of berberine was observed, and corticosterone could inhibit the uptake of berberine, with IC50 values of 0...

The family of inward rectifying potassium channels (Kir channels) plays crucial roles in the regulation of heart rhythms, renal excretion, insulin release, and neuronal activity. Their dysfunction has been attributed to numerous diseases such as cardiac arrhythmia, kidney failure and electrolyte imbalance, diabetes mellitus, epilepsy, retinal degeneration, and other neuronal disorders. We have recently demonstrated that the melanocortin-4 receptor (MC4R), a Gαs-coupled GPCR, regulates Kir7.1 activity through a mechanism independent of Gαs and cAMP...

Milrinone is an invaluable agent in the treatment of end-stage heart failure patients who are refractory to optimal medical therapy. In addition to its use in acute decompensated heart failure, milrinone can also be employed as a home infusion therapy or a bridge to cardiac transplant. Concerns about its adverse effects, such as an increased risk of arrhythmias and hypotension, often limit the doses of milrinone used in clinical practice. In addition, milrinone is infrequently used or avoided entirely in patients with acute renal failure or end-stage renal disease since the drug is primarily cleared by renal excretion...

BACKGROUND: An alleged association of chronic use of thiazide diuretics with an increased risk of bone fragility fractures has been highlighted by a relatively recent prospective cohort study. However, the concept that thiazides exert a beneficial effect on osteoporosis is still a predominant view. This effect would be mediated by the decrease in renal clearance of calcium ions, a pharmacological feature recognized for a long time now to this class of drugs, as opposed to the increase in calcium urinary excretion attributed instead to loop diuretics, i...

Hyperkalemia, defined as serum potassium concentrations greater than 5.0 to 5.5 mEq/L, is a frequent occurrence in clinical practice because of the increasing incidence and prevalence of CKD. Patients at risk for this disorder are commonly treated with drugs that interfere in the renin-angiotensin-aldosterone system, thereby enhancing the occurrence and prevalence of this disorder. Discontinuation of these drugs because of the development of hyperkalemia deprives these patients the renal-protective and cardiovascular benefits this class of pharmacology has been shown to provide...

1. Venetoclax is a novel, small molecule B-cell lymphoma-2 (BCL-2) inhibitor that has demonstrated clinical efficacy in a variety of haematological malignancies. Since venetoclax is an inhibitor of P glycoprotein (P-gp) transporter, a study was conducted in healthy, female volunteers to evaluate the effect of venetoclax on the pharmacokinetics of digoxin, a P-gp probe substrate. 2. Volunteers received a single oral dose of digoxin (0.5 mg) with or without a single oral dose of venetoclax (100  mg). Serial blood samples were obtained for pharmacokinetic assessments of digoxin and venetoclax and serial urine samples were obtained for measurement of digoxin concentrations...

Aminoglycosides pharmacokinetics (PK) is expected to change in neonates with perinatal asphyxia treated with therapeutic hypothermia (PATH). Several amikacin dosing guidelines have been proposed to treat neonates with (suspected) septicemia, however, none provide adjustments in the case of PATH. Therefore, we aimed to quantify the differences in amikacin PK between neonates with and without PATH to propose suitable dosing recommendations.Based on amikacin therapeutic drug monitoring data collected retrospectively from neonates with PATH, combined with a published dataset, we assessed the impact of PATH on amikacin PK using population modelling...
