Interventions to block the renin-angiotensin system (RAS) halt the progression of renal lesions in renal damage models. It has recently also been reported that established glomerulosclerosis can be reversed by pharmacologic blockade of the RAS. It was the aim of this study to confirm that high doses of angiotensin-converting enzyme (ACE) inhibitors reverse(More)
Adipocytes secrete several biologically active substances that are presumed to be involved in obesity-related hypertension. There are no reports that deal with the relationship between plasma adiponectin concentration and blood pressure (BP). To evaluate the role of adiponectin in essential hypertension 33 patients with essential hypertensive (EHP) (12(More)
The Streptozotocin (STZ) model of diabetes is commonly used for studies of diabetic nephropathy although the histological lesions of the kidney are mild and do not resemble those seen in diabetic patients. The SHR/N-cp rat model of type II diabetes spontaneously develops pronounced abnormalities in renal histology. In the present study, we compared renal(More)
Cardiovascular complications are a major clinical problem in patients with chronic kidney disease and end stage renal failure. Death from cardiac causes accounts for 40%-50% of all deaths in these patients and is thus up to 20 times more common in uremic patients than in the general population. Cardiovascular pathology in patients with renal failure is(More)
Dyslipidemia is a known cardiovascular risk factor in subjects without kidney disease. In patients with kidney disease, however, the relation of dyslipidemia to cardiovascular risk is confounded and the underlying pathomechanisms are complex. Statins have proven to be highly effective in patients with initial stages of chronic kidney disease (CKD). Definite(More)
BACKGROUND AND AIM Adiponectin is an anti-inflammatory protein secreted almost exclusively by adipocytes which improves insulin sensitivity and presents antiatherogenic properties. Plasma adiponectin concentration is almost 3 times higher in hemodialysis patients and markedly decreased after successful kidney transplantation. However, until now, there are(More)
Diabetic nephropathy is the leading cause of end-stage renal disease. Dopamine receptors are involved in the regulation of renal hemodynamics and may play a role in diabetes-induced hyperfiltration. To test this hypothesis, we investigated the renal effect of a dopamine D3 receptor antagonist (D3-RA) in hypertensive type II diabetic SHR/N-cp rats. Lean and(More)
BACKGROUND Adiponectin, a protein secreted exclusively by adipocytes, is presumed to be involved in the pathogenesis of atherosclerosis and insulin resistance. An elevated plasma adiponectin concentration was found in ESRD patients on hemodialysis (HD). However, the role of kidneys in adiponectin biodegradation/elimination is unknown. Therefore, we assessed(More)
On September 6, 2001, Professor Fernando Valderrabano (Hospital Gregorio Marañon, Madrid) died at the age of 59 years. He was a leading figure in Spanish nephrology, a full professor of Medicine/Nephrology at the University Complutense of Madrid, and an outstanding scientist who published more than 300 articles in medical journals. He was a very intelligent(More)
In this review paper we would like to summarized the current knowledge concerning the  pathogenesis and treatment of ischemic nephropathy. Epidemiological data suggest that the prevalence of ischemic nephropathy increases, especially among older individuals. The pathogenesis of this disease is more complex than just narrowing of the renal artery due to(More)
