Dent disease classically combines low-molecular-weight proteinuria, hypercalciuria with nephrocalcinosis, and renal failure. Nephrotic range proteinuria, normal calciuria, and hypokalemia have been rarely reported. It is unknown whether the changes in phenotype observed over time are explained by a decrease in glomerular filtration rate (GFR) or whether there is any phenotype-genotype relationship. To answer this we retrospectively analyzed data from 109 male patients with CLCN5 mutations (Dent-1) and 9 patients with mutation of the OCRL gene (Dent-2)...

BACKGROUND: Animal studies have highlighted the role of vascular mineralocorticoid receptor during Cyclosporine A-induced nephrotoxicity. Mineralocorticoid receptor antagonists could improve kidney survival but are not commonly used during renal impairment and in association with several immunosuppressive drugs due to a supposed higher risk of adverse events. We tested the tolerance of eplerenone according to its expected adverse events: hyperkalemia, metabolic acidosis, hypotension, acute kidney failure, or any other adverse event...

BACKGROUND: Aldosterone-producing adenoma is classically treated by unilateral adrenalectomy. Severe hyperkalemia, related to adrenal insufficiency, have been already reported after surgery. We describe here 4 male patients who, despite subnormal kalemia, developed a failure of the renin-aldosterone (RA) axis, resulting in a decrease in extracellular fluid volume (ECFV) following surgery METHODS: PA diagnosis was established according to French recommendations. Unilateral adrenalectomy was performed in all...

Aldosterone plays an essential role in the maintenance of fluid and electrolyte homeostasis in the distal nephron. Monogenic forms of mineralocorticoid hypertension result from genetic defects leading to excessive production of aldosterone (or other mineralocorticoids) from the adrenal cortex or to illegitimate mineralocorticoid effects in the kidney. They are characterized in the majority of cases by early onset, severe or resistant hypertension and associated with suppressed renin levels. Depending on their causes, these diseases are distinguished at the clinical and biochemical level and differently affect aldosterone levels and kalemia...

CONTEXT: The role of vasopressin (AVP) in the pathophysiology of primary aldosteronism (PA) remains unclear. OBJECTIVES: The primary aim of this study was to investigate AVP secretion in PA by measuring the plasma concentration of copeptin (PCop), the C-terminal portion of provasopressin. The secondary aim was to assess renal sensitivity to AVP. DESIGN AND SETTING: This was a cross-sectional study in a tertiary-care hospital. PROTOCOL: We recruited 115 patients with PA, 48 patients with essential hypertension (EH), and 108 normotensive healthy subjects (HS)...

BACKGROUND: Combination treatments for hypertension most often include a renin-angiotensin-aldosterone system (RAAS) inhibitor. However, systolic blood pressure (SBP) remains difficult to control. Non-RAAS-inhibiting strategies such as calcium channel blocker/thiazide-like diuretic combinations may offer effective alternatives. METHODS: Hypertensive diabetic patients with microalbuminuria were included in this retrospective, post-hoc analysis of the Natrilix SR Versus Enalapril Study in Hypertensive Type 2 Diabetics With MicrOalbuminuRia (NESTOR) trial if they were uncontrolled on monotherapy (indapamide slow release (SR) 1...

BACKGROUND: Electrolyte derangements are common sequel of traumatic brain injury. Use of intravenous fluids, diuretics, syndrome of inappropriate ADH secretion and cerebral salt washing are some of the factors responsible for this. Proper in time detection followed by appropriate treatment not only improves neurological status but also decrease morbidity and mortality. This study was conducted to know serum derangements of different electrolytes in patients with traumatic brain injury...

Diabetes is associated with an increased risk of sudden cardiac death, but the underlying mechanisms remain unclear. Our goal was to investigate changes occurring in the action potential duration (APD) and conduction velocity (CV) in the diabetic rabbit ventricle, and delineate the principal ionic determinants. A rabbit model of alloxan-induced diabetes was utilized. Optical imaging was used to record electrical activity in isolated Langendorff-perfused hearts in normo-, hypo- and hyper-kalemia ([K(+)]o=4, 2, 12 mM respectively)...

Mrs. A, a 62 year old patient with a history of hypertension, polyuria and polydipsia is hospitalized after a malaise. A severe hypokalemia, which is the cause of the polyuria and polydipsia, is discovered. The presence of hypertension and hypokalemia arises suspicion of a primary hyperaldosteronism and the plasma levels of renin and aldosterone are measured. Elevated aldosterone levels are combined with high plasma renin concentrations which permits to rule out primary hyperaldosteronism. Further explorations reveal a subocclusive ostial stenosis of the right renal artery...

Hospitals have at their disposal large databases that may be considered for reuse. The objective of this work is to evaluate the impact of a drug on a specific laboratory result by analyzing these data. This analysis first involves building a record of temporal patterns, including medical context, of drug prescriptions. Changes in outcome due to these patterns of drug prescription are assessed using short phases of the inpatient stay compared to monotonous changes in the laboratory result. To illustrate this technique, we investigated potassium chloride supplementation and its impact on kalemia...

INTRODUCTION: Long-time consumption of narcotics leads to altered mental status of the addict. It is also connected to damages of different organic systems and it often leads to appearance of multiple organ failure. Excessive narcotics consumption or abuse in a long time period can lead to various consequences, such as atraumatic rhabdomyolysis, acute renal failure and electrolytic disorders. Rhabdomyolysis is characterized by injury of skeletal muscle with subsequent release of intracellular contents, such as myoglobin, potassium and creatine phosphokinase...

We report on two patients on chronic hemodialysis, who presented with typical symptoms of hyperkalemia (lower limb paresia and characteristic electrocardiogram [ECG]) for an only mildly increased kalemia (6.1 and 6.2 mEq/L), values that are frequently seen in asymptomatic patients on chronic hemodialysis. Their common denominator was a concomitant hypocalcemia (7.5 et 6.4mg/dL) induced by cinacalcet treatment. Hypocalcemia has very likely precipitated the occurrence of clinical and electrocardiological manifestations of hyperkalemia...
