BACKGROUND Increased sympathetic nerve activity may contribute to the progression of renovascular hypertension. Because previous results have been inconclusive, we investigated whether renovascular hypertensives show increased total and regional sympathetic nerve activity. METHODS AND RESULTS Sixty-five patients underwent renal angiography and(More)

A multicenter, selection-adjusted comparison of patient and technique survivals on cause of death between patients treated with hemodialysis and peritoneal dialysis. Why are reported relative mortality risks(More)
Because of the growing evidence that hypertensive disease is accompanied by immunological dysfunction, we have investigated autoimmunity in patients with malignant hypertension. Peptides corresponding to the sequence of the second extracellular loops of the human alpha 1-adrenergic receptor and the M2-muscarinic receptor were used as antigens in an ELISA.(More)
Hypertension with renal artery stenosis is associated with both an activated renin-angiotensin system and elevated sympathetic activity. Therefore, in this condition it may be favorable to use a therapeutic modality that does not reflexly increase heart rate, renin secretion, and sympathetic nervous activity. The purpose of the present study was to assess(More)
Increased T-lymphocyte reactivity against human arterial antigen was significantly more common in a group of 20 patients with previously malignant essential hypertension than in matched control subjects. Serum-levels of IgG and IgM and the prevalence of autoantibodies were also significantly higher in the patients. It is suggested that these changes,(More)
BACKGROUND Darbepoetin alfa (DA) has been shown to be an effective treatment of anaemia in patients with chronic kidney disease (CKD) not on dialysis (NoD). EXTEND is an observational study assessing the effectiveness of DA administered once biweekly (Q2W) or monthly (QM) in a general CKD-NoD population. METHODS Adult CKD-NoD patients starting DA Q2W/QM(More)
UNLABELLED BACKGROUND The existence of unilateral adrenal hyperplasia (AH) has been considered a rare cause of primary hyperaldosteronism (PA). METHODS In a prospective study we screened for PA in a non-selected (NSP) and selected hypertensive population (SP), to define the cause of PA. We included 353 consecutive patients with hypertension; age 20 to(More)
20alpha-Hydroxysteroid dehydrogenase (20alpha-OH-SDH) activity was determined in the first generation corpora lutea from prepubertal rats injected with 10 I.U. of pregnant mare's serum gonadotrophin (PMSG) on day 30. The enzyme was not detectable in 1-9-day-old corpora lutea but a significant activity was seen on day 10. Enzyme activity increased during day(More)
BACKGROUND Extended dosing of the erythropoiesis-stimulating agent (ESA) darbepoetin alfa (DA) once biweekly or monthly reduces anaemia treatment burden. This observational study assessed outcomes and dosing patterns in patients with chronic kidney disease not on dialysis (CKD-NoD) commencing extended dosing of DA. METHODS Adult CKD-NoD patients starting(More)
BACKGROUND Relationship of left ventricular diastolic dysfunction (LVDD) with parameters that could provide more information than hemodynamic renal indexes has not been clarified. We aimed to explore the association of comprehensive renal parameters with LVDD in a community-based elderly population. METHODS 1,166 community residents (aged ≥ 65 years, 694(More)
