OBJECTIVE Burst-forming unit erythroid and colony-forming unit erythroid growth in vitro is lower in studies of continuous ambulatory peritoneal dialysis patients than healthy controls. Burst-forming unit erythroid growth was potentiated by addition of 1alpha,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] and normalized by erythropoietin (Epo) therapy,(More)
In 10 patients with chronic renal failure (CRF), undergoing hemodialysis, we studied respiratory muscle strength and endurance. The data obtained was compared with those acquired from 10 age-, sex-, weight- and height-matched normal volunteers. Maximal static inspiratory pressures (PImax) measured at residual volume and maximal static expiratory pressure(More)
Many renal diseases, including transplant rejection, are mediated by mononuclear cells. Interleukin-15 (IL-15) has been recently described as a cytokine with IL-2-like activity. IL-15 is an effective leukocyte growth factor, activator, and chemoattractant. In rejected human kidney allografts, elevated IL-15, but not IL-2, mRNA is expressed, suggesting a(More)
We describe 3 patients who developed extreme hypermagnesemia due to ingestion of water of the Dead Sea, which would have been fatal were it not for the protective effects of the accompanying hypercalcemia. We emphasize the clinical features of this condition and the importance and effectiveness of early hemodialysis as the main modality of treatment.
Twelve stable cirrhotic patients with ascites received a 20 mL/kg water load. Seven patients had abnormal water excretion (27.3% +/- 5.4% of the water load in 5 hours) and a minimal urine osmolality of 262 mosmol/kg water. Five patients excreted 82.6% in 5 hours and had a minimal urine osmolality of 65 mosmol/kg water. Mean plasma arginine vasopressin(More)
BACKGROUND In a previous study we demonstrated the inhibitory effect of 1,25-dihydroxyvitamin D (1,25(OH)(2)D(3)) and its less calcaemic analog 1,24(OH)(2)D(2) on the production of tumour necrosis factor alpha (TNFalpha) by human peritoneal macrophages. The aim of the present study is to examine whether this vitamin D inhibition of TNFalpha is mediated by(More)
We determined serum high-density lipoprotein cholesterol content and analyzed the approtein structure of the various lipoprotein fractions in 21 patients on chronic hemodialysis. High-density lipoprotein cholesterol was significantly reduced in all patients as compared with 11 normal persons (mean +/-1 standard deviation: 26 +/- 13 vs. 52 +/- 9 mg per 100(More)
BACKGROUND Ketamine is an anesthetic drug. Subanesthetic doses of ketamine have been shown to reduce interleukin-6 concentrations after surgery and to reduce mortality and the production of tumor necrosis factor alpha and interleukin 6 in septic animals. Similarly, adenosine was shown to reduce tumor necrosis factor alpha and mortality of septic animals.(More)
The effects of phosphate (PO4) removal from Krebs Henseleit buffer on freshly isolated rat proximal tubules (rPT) were assessed by measuring Ca2+ uptake (nmol/mg protein), cellular adenosine triphosphate (ATP) (nmol/mg), tissue K+ content (nmol/mg) and lactate dehydrogenase (LDH) as an index of cell integrity. Ca2+ uptake increased by 50% in rPT incubated(More)
