In autosomal dominant polycystic kidney disease (ADPKD), arginine vasopressin (AVP) accelerates cyst growth by stimulating cAMP-dependent ERK activity and epithelial cell proliferation and by promoting Cl(-)-dependent fluid secretion. Tolvaptan, a V2 receptor antagonist, inhibits the renal effects of AVP and slows cyst growth in PKD animals. Here, we determined the effect of graded concentratio...
Amyotrophic lateral sclerosis (ALS) patients rarely present with either syndrome of inappropriate antidiuretic hormone secretion or generalized edema. Tolvaptan is a selective vasopressin V2 receptor antagonist that produces effective aquaresis, and its use in ALS patients has not been previously reported. A 50-year-old male ALS patient was admitted because of both generalized edema and dilutio...
AIMS Increases in body weight (BW) are important determinants for hospitalization in ambulatory patients with heart failure (HF), but have not yet been explored in patients hospitalized for worsening HF. We explore the relationship between change in BW after hospitalization for worsening HF and risk for repeat hospitalization and mortality in the EVEREST trial. METHODS AND RESULTS The EVEREST...
To investigate the possible role of arginine vasopressin in maintaining high blood pressure of spontaneously hypertensive rats (SHR), the effect of two arginine vasopressin pressor antagonists on mean arterial pressure and the pressor responsiveness to exogenous arginine vasopressin were studied in conscious, freely moving SHR and in Wistar-Kyoto rats (WKY). Intravenous injections of either d(C...
During the last years, the results of several trials on heart failure treatment were published or presented at international meetings. The new perspectives concern drug therapy and non-pharmacological strategies, such as cardioverter-defibrillators, biventricular resynchronization and implantable assist devices. Trials on beta-blockers extended the indication to patients with advanced heart fai...
Chronic kidney disease (CKD) is often complicated with advanced heart failure because of not only renal congestion and decreased renal perfusion but also prolonged use of diuretics at higher doses, which sometimes results in hyponatremia. Preoperative CKD is known to be associated with poor prognosis after heart transplantation (HTx). We experienced a stage D heart failure patient with CKD and ...
This study compares the effect of arginine-vasopressin with phenylephrine on arterial pressure, heart rate, and renal sympathetic nerve activity in conscious rabbits with and without functional arterial baroreflexes and in rabbits with lesions of the area postrema. In intact rabbits, progressive infusions of arginine-vasopressin result in large decreases in renal sympathetic nerve activity and ...
