We describe the first case of distal renal tubular acidosis (dRTA) associated with primary sclerosing cholangitis. A 26-year-old Lao-Thai male patient presented with severe jaundice, metabolic acidosis and hypokalaemia. He was diagnosed of dRTA. Liver transplantation resulted in correction of electrolyte disturbances and hyperbilirubinaemia. A fludrocortisone-furosemide test revealed normal urinary acidification, demonstrating no residual dRTA. This observation suggests that dRTA may be an early manifestation of bilirubin-associated nephropathy or the consequence of an immune mechanism...

Meldonium (3-(2,2,2-trimethylhydrazinium)propionate) is the most potent clinically used inhibitor of organic cation transporter 2 (OCTN2). Inhibition of OCTN2 leads to a decrease in carnitine and acylcarnitine contents in tissues and energy metabolism optimization-related cardioprotective effects. The recent inclusion of meldonium in the World Anti-Doping Agency List of Prohibited Substances and Methods has raised questions about the pharmacokinetics of meldonium and its unusually long elimination time. Therefore, in this study, the rate of meldonium washout after the end of treatment was tested with and without administration of carnitine, γ-butyrobetaine (GBB) and furosemide to evaluate the importance of competition for OCTN2 transport in mice...

Free intracellular calcium ([Ca2+]i), in addition to being an important second messenger, is a key regulator of many cellular processes including cell membrane potential, proliferation and apoptosis. In many cases, the mobilization of [Ca2+]i is controlled by intracellular store activation and calcium influx. We have investigated the effect of several ion channel modulators, which have been used to treat a range of human diseases, on [Ca2+]i release, by ratiometric calcium imaging. We show that six such modulators (Amiodarone (Ami), Dofetilide (Dof), Furosemide (Fur), Minoxidil (Min), Loxapine (Lox), and Nicorandil (Nic)) initiate release of [Ca2+]i in prostate and breast cancer cell lines, PC3 and MCF7, respectively...

PURPOSE OF REVIEW: The kidney, like most other organs, has a reserve capacity that can be utilized in times of increased physiologic demand. The ability to quantify this renal reserve function across various parts of the nephron (glomerular and tubular) has been an area of increased investigation over the past several years. In this review, we discuss several techniques that have been developed to interrogate the maximal physiologic capacity of the injured kidney. RECENT FINDINGS: Although protein loading has been established as an ideal method to investigate glomerular filtration capacity in healthy kidneys, other methods such as the antagonism of the renin-angiotensin-aldosterone system have demonstrated promise as a method to determine underlying glomerular disease in those with acute kidney injury and other comorbidities (e...

AIMS: Loop diuretics are first-line medications for congestive heart failure (CHF); however, they are associated with serious adverse effects, including decreased renal function, and sympathetic nervous and renin-angiotensin system activation. We tested whether tolvaptan, a vasopressin V2-receptor antagonist, could reduce unfavourable furosemide-induced effects during CHF treatment. METHODS AND RESULTS: Sixty patients emergently hospitalized owing to CHF-induced dyspnea were randomly assigned to receive either 40 mg intravenous furosemide daily or 7...

OBJECTIVE: Recent evidence points to the effectiveness of spironolactone vs placebo in the treatment of resistant hypertension (RH). However, placebo is rarely a realistic treatment choice in uncontrolled hypertension. Using meta-analysis, we assessed the effectiveness of alternative 4 line anti-hypertensive agents in comparison to 4 line spironolactone/eplenerone in RH. DESIGN AND METHOD: Pubmed, EMBASE and the Cochrane library were systematically searched for randomised and non-randomised studies that compared any 4 line anti-hypertensive agent to spironolactone/eplenerone in RH...

OBJECTIVE: Refractory ascites reduces the quality of life of liver cirrhosis patients. Albumin preparation and diuretics, such as furosemide, have been used to treat refractory ascites, but the effect was poor in many patients. In this study, we analyzed patients treated with tolvaptan (TLV) at our hospital and investigated predictors of the effect. METHODS: The subjects were 70 patients for whom TLV was introduced to treat refractory ascites who could be analyzed between November 2013 and March 2015 at our hospital...

The diagnostic steps for primary aldosteronism (PA) include case screening tests, confirmatory tests, and localization. The aim of this study was to identify useful confirmatory tests and their cut-off values for differentiating the subtype of primary aldosteronism, especially in unilateral PA, such as aldosterone-producing adenoma, and bilateral PA, such as idiopathic hyperaldosteronism. Seventy-six patients who underwent all four confirmatory tests, the captopril-challenge test (CCT), furosemide upright test (FUT), saline infusion test (SIT), and ACTH stimulation test (AST), and who were confirmed to have an aldosterone excess by adrenal venous sampling (AVS) were recruited...

Three experiments assessed potential changes in the rat's perception of sodium chloride (NaCl) during a state of sodium appetite. In Experiment 1, sodium-sufficient rats licking a range of NaCl concentrations (0.028-0.89M) in 15s trials showed an inverted U-shaped concentration response function peaking at 0.281M. Depleted rats (furosemide) showed an identical function, merely elevated, suggesting altered qualitative or hedonic perception but no change in perceived intensity. In Experiment 2, sodium-depleted rats were tested with NaCl, sodium gluconate, and potassium chloride (KCl; 0...

A 60-year-old man initially presented with pain in the right upper quadrant in October 2010. A computed tomography (CT) scan of the abdomen pelvis completed at that time showed a mass at the junction of the body and tail of the pancreas and multiple large liver lesions. A CT-guided liver biopsy revealed low-grade neuroendocrine carcinoma. The patient was initially started on systemic treatment with sunitinib (Sutent) and octreotide. He developed intolerable side effects, including nausea and migraine. Therapy was discontinued in October 2011, when a CT scan revealed evidence of disease progression...

Detailed in this unit is a mouse model of overactive bladder and urinary incontinence based on diuretic stress-induced urination. The procedure involves the use of a unique, highly sensitive, and automated urine capturing method to measure urinary latency, frequency, and void volume. Although this method was first described and validated using an anti-muscarinic drug used for treating overactive bladder, subsequent work has shown that effective non-cholinergic agents can be detected. These findings indicate good predictive value for this model regarding the possible clinical utility of test agents as treatments for overactive bladder, regardless of their site of action...

Some widely prescribed drugs are sparsely metabolized and end up in the environment. They can thus be a focal point of ecotoxicity, either themselves or their environmental transformation products. In this context, we present a study concerning furosemide, a diuretic, which is mainly excreted unchanged. We investigated its biotransformation by two environmental fungi, Aspergillus candidus and Cunninghamella echinulata. The assessment of its ecotoxicity and that of its metabolites was performed using the Microtox test (ISO 11348-3) with Vibrio fischeri marine bacteria...

History of sodium depletion cross-sensitizes the effects of drugs of abuse. The objective of the present study was to find out if history of sodium depletion also cross-sensitizes a natural reward such as sugar intake in the rat. Sodium depletion was induced by furosemide combined with removal of ambient sodium for 24 h; it was repeated seven days later. The depletion was immediately followed by 0.3 M NaCl intake in a sodium appetite test (active sodium repletion). Seven days after the last depletion, hydrated and fed (need-free) sucrose-naïve animals were offered 10% sucrose in a first 2-h sucrose test...
