Aquaporin-2 in the early stages of the adenine-induced chronic kidney disease model.

PLoS One

Chronic kidney disease (CKD) is one of the leading health problems in the world. It is silent in the early stages and gradually progresses, inducing renal physiological and structural alterations. Moreover, CKD is associated with impaired life quality, increased risk for cardiovascular diseases, and reduced life expectancy.

Metabolically stable apelin analogs: development and functional role in water balance and cardiovascular function.

Clin Sci (Lond)

January 2025

Center for Interdisciplinary Research in Biology, College de France, Institut National de la Santé et de la Recherche Médicale, Paris, France.

Apelin, a (neuro) vasoactive peptide, plays a prominent role in controlling water balance and cardiovascular functions. Apelin and its receptor co-localize with vasopressin in magnocellular vasopressinergic neurons. Apelin receptors (Apelin-Rs) are also expressed in the collecting ducts of the kidney, where vasopressin type 2 receptors are also present.

Background: Hyponatremia is one of the complicating findings in acute decompensated heart failure. Decrease in cardiac output and systemic blood pressure triggers activation of renin-angiotensin-aldosterone system, antidiuretic hormone, and norepinephrine due to the perceived hypovolemia. Fluid-overloaded heart failure patients are commonly treated with loop diuretics, acutely decompensated heart failure patients tend to be less responsive to conventional oral doses of a loop diuretic, while other different diuretics could work in different part of nephron circulation system.

Diuretic Potentiation Strategies in Acute Heart Failure.

JACC Heart Fail

January 2025

Department of Medicine, University of Mississippi Medical Center, Jackson, Mississippi, USA; Baylor Scott and White Research Institute, Baylor Scott and White Health, Dallas, Texas, USA. Electronic address:

Several trials have evaluated diuretic-based strategies to improve symptoms and outcomes in patients with acute heart failure (AHF). The authors sought to summarize the effect of different combination strategies on symptoms, physical signs, physiological variables, and outcomes in patients with AHF. Twelve trials were identified that assessed the addition of thiazide diuretics, sodium-glucose cotransporter 2 inhibitors, mineralocorticoid receptor antagonists, vasopressin receptor antagonists, carbonic anhydrase inhibitors, or loop diuretic intensification to conventional therapy for AHF.
