A male patient with acute renal failure (ARF) due to large B-cell non-Hodgkin lymphoma infiltration of kidney is presented. The diagnosis was suspected because of coincidence of ARF and tumor lysis syndrome non-responsive to conservative renal therapies. A renal biopsy confirmed diagnosis and appropriate chemotherapy led to complete improvement of renal function.  

The exposure of the fetus to a hyperglycemic environment promotes the development of hypertension and renal dysfunction in the offspring at adult age. We evaluated the role of renal nerves in the hypertension and renal changes seen in offspring of diabetic rats. Diabetes was induced in female Wistar rats (streptozotocin, 60 mg/kg ip) before mating. Male offspring from control and diabetic dams ...

Systemic arterial vasodilatation has been implicated in the pathogenesis of sodium retention in cirrhosis. Hydrophobic bile acids, which have vasodilatory actions, may be involved. Ursodeoxycholic acid, a hydrophilic bile acid, could potentially decrease systemic arterial vasodilatation, possibly due to its antioxidant effects, and improve sodium handling in cirrhosis. The effects of ursodeoxyc...

Uricase-deficient mice develop uric acid nephropathy, with high mortality rates before weaning. Urate excretion was quantitated and renal function was better defined in this study, to facilitate the use of these mice as a model for evaluating poly(ethylene glycol)-modified recombinant mammalian uricases (PEG-uricase) as a potential therapy for gout and uric acid nephropathy. The uric acid/creat...

Ezekowitz et al. (1) recently reported lack of benefit of angiotensin-converting enzyme (ACE) inhibitors on mortality in patients with chronic heart failure (CHF) in whom estimated creatinine clearance was below 60 ml/min, as opposed to a beneficial effect in those with creatinine clearance above 60 ml/min. The researchers attribute this lack of benefit to a possible interaction between aspirin...

The factors responsible for congestive heart failure as a clinical syndrome may be multiple. Although decreased cardiac output relative to inflow produces a moderate increase in venous pressure, there is a concomitant decrease in renal blood flow which may contribute to a decreased renal excretion of sodium. There is also a decrease in hepatic inactivation ( ? due to congestion) of adrenal cort...

The circadian clock plays an important role in the regulation of physiological processes, including renal function and blood pressure. We have previously shown that the circadian protein period (Per)1 regulates the expression of multiple Na(+) transport genes in the collecting duct, including the α-subunit of the renal epithelial Na(+) channel. Consistent with this finding, Per1 knockout mice e...
