15Nephrotoxicity is often underestimated because renal clearance in animals is higher compared to in humans. This paper aims to illustrate the potential to fill in such pharmacokinetic gaps between animals and humans using a microfluidic kidney model. As an initial demonstration, we compare nephrotoxicity of a drug, administered at the same total dosage, but using different pharmacokinetic regimens. Kidney epithelial cell, cultured under physiological shear stress conditions, are exposed to gentam
BACKGROUND: In vitro studies of peritoneal dialysis (PD) solutions demonstrated that a biocompatible fluid with neutral-pH and low glucose degradation products (LF) has better biocompatibility than a conventional acidic lactate-buffered fluid (CF). However, few clinical trials have investigated the effects of the biocompatible solution on residual renal function (RRF). We performed a prospective, randomized trial with patients starting continuous ambulatory peritoneal dialysis (CAPD). METHODS: N

Traditional approaches to pathophysiology are advancing but still have many limitations that arise from real biologic systems and their associated physiological phenomena being too complicated. Microfluidics is a novel technology in the field of engineering, which provides new options that may overcome these hurdles. Microfluidics handles small volumes of fluids and may apply to various applications such as DNA analysis chips, other lab-on-a-chip analyses, micropropulsion, and microthermal techn
BACKGROUND: The phospholipase A(2) receptor (PLA2R) is a major antigen found in patients with idiopathic membranous nephropathy (MN). The relationship of genetic polymorphisms of PLA2R with the susceptibility and clinical outcomes of this disease is unknown. METHODS: We studied 199 patients with idiopathic MN followed up for 3.7 ± 3.2 years. We enrolled 33 patients with secondary MN and 356 subjects with normal blood pressure and no proteinuria. PLA2R single nucleotide polymorphisms (SNPs) were
Using kidney-on-a-chip, researchers can create experimental environments resembling the physiological environments in human organs and obtain experimental results that better reflect human physiology. Kidney-ona- chip can be used to overcome the drawbacks of traditional animal models and to more effectively identify drug effects, interactions, and drug-induced nephrotoxicity.
TNF superfamily member 13 (TNFSF13) has been identified as a susceptibility gene for IgA nephropathy in recent genetic studies. However, the role of TNFSF13 in the progression of IgA nephropathy remains unresolved. We evaluated two genetic polymorphisms (rs11552708 and rs3803800) and plasma levels of TNFSF13 in 637 patients with IgA nephropathy, and determined the risk of ESRD according to theses variable. Neither of the examined genetic polymorphisms associated with a clinical outcome of IgA ne
BACKGROUND: Acute kidney injury (AKI) is commonly encountered in clinical practice and is associated with poor patient outcomes and increased health care costs. Despite it posing significant challenges for clinicians, effective measures for AKI prediction and prevention are lacking. Previously published AKI prediction models mostly have a simple design without external validation. Furthermore, little is known about the process of linking model output and clinical decisions due to the black-box n
HA is associated with the development of AKI and high mortality in hospitalized patients. Replacement of albumin after the development of AKI may contribute to renal recovery. Further clinical trials are warranted.
BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a cardiorespiratory support technique for patients with circulatory or pulmonary failure. Frequently, large-volume fluid resuscitation is needed to ensure sufficient extracorporeal blood flow in patients initiating ECMO. However, excessive overhydration is known to increase mortality in critically ill patients. Therefore, in order to define a tolerant volume range in patients undergoing ECMO treatment, the association between cumulative f
Inhibition of renal prostaglandin synthesis by non-steroidal anti-inflammatory drugs (NSAIDs) causes various electrolyte and acid-base disturbances including sodium retention (edema, hypertension), hyponatremia, hyperkalemia, and decreased renal function. Decreased sodium excretion can result in weight gain, peripheral edema, attenuation of the effects of antihypertensive agents, and rarely aggravation of congestive heart failure. Although rare, NSAIDs can cause hyponatremia by reducing renal fr
