Hemodynamic improvement in patients suffering from both septic shock and renal failure who received hemofiltration suggested that an extrarenal epuration technique could be of interest in patients with septic shock alone. However, most of the studies using continuous venovenous hemofiltration (CVVH) in this setting evidenced neither cytokine clearance nor significant reduction in their plasma level. Lack of significant clearance was explained in part by the small size of the membrane pores. Therefore, we investigated the effects of large-pore membrane hemofiltration (LPHF) during endotoxic shock in pigs on interleukin 6 (IL-6) and interleukin 10 (IL-10) clearances, and on right ventricular (RV)-vascular coupling. Thirteen anesthetized healthy pigs weighing 20-30 kg were divided into two groups. In the Endo group (n = 6), the pigs received a 0.5-mg/kg endotoxin infusion over a period of 30 mins from T0 to T30. In the EndoHF group (n = 7), LPHF (cutoff = 80 kDa) and an ultrafiltration rate of 45 mL/kg/h were started 30 mins after the end of the endotoxin infusion, from T60 to T240. In this model of porcine endotoxic shock, LPHF was responsible for a significant clearance of IL-6 (20 mL/min) and Il-10 (14 mL/min), and for an improvement in RV-vascular coupling. [less ▲]

Chronic renal failure (CRF) is a common complication in heart transplant patients. Serum creatinine has clear limitations for the detection and estimation of glomerular filtration rate (GFR). Various creatinine-based formulae are classically used for GFR estimation, but little scientific evidence exists for such use in a heart transplant population. GFR was measured using the plasmatic clearance of the glomerular tracer Cr-51-EDTA in 27 heart transplant patients with two measures for 22 of the patients. Forty-nine measures were thus available for analysis. The precision and accuracy (Bland and Altman analysis) of the Cockcroft, simplified Modified Diet in Renal Diseases (MDRD) and new Mayo Clinic formulae were compared. The mean GFR of the population was 39 +/- 15 mL/min/1.73 m(2). All formulae were well correlated with the GFR. With the Bland and Altman analysis, the accuracy of the MDRD formula appeared higher than that of the Cockcroft or the Mayo Clinic formulae (bias of +12 mL/min/1.73 m(2), vs. +19.9 mL/min/1.73 m(2), and +22.1 mL/min/1.73 m(2), respectively). The difference between the estimated and measured GFR was higher than 20 mL/min/1.73 m(2) in 51% and 55% cases when using the Cockcroft and the Mayo Clinic formulae respectively, whereas the difference was only noted in 14% cases when the MDRD was used. Among creatinine-based formulae, the MDRD appears the most precise and accurate for estimating the GFR in heart transplant patients. However, when the GFR must be measured with high accuracy, we recommend the use of a reference method like inulin or Cr-51-EDTA plasma clearance techniques. [less ▲]

Bone metabolism is very frequently disturbed in end stage renal failure hemodialyzed, with secondary hyperparathyroidism development but also serious potential cardiovascular consequences. New treatments will be available very soon in Europe such as new phosphate binders, vitamin D2 analogues or calcimimetics to fight against such medical diseases, with the hope of less risk for vascular complications. The real place of such new medical opportunities needs to be determined. Moreover, studies with morbidity and mortality end-points are waited before estimating the real importance of these new therapeutic tools. [less ▲]

Primary aldosteronism is a rare cause of hypertension. However, its incidence seems to be underestimated. It is important to identify this syndrom since the disease is potentially curable. In the present paper, we depict different forms of primary aldosteronism as well as the diagnostic procedures. When the diagnosis is suspected (hypertension associated to spontaneous or diuretic-induced hypokaliemia), the more efficient screening test is the determination of the aldosteron/renin ratio. Saline infusion or posture tests can thereafter confirm the diagnosis. Differential diagnosis between bilateral and unilateral forms of primary aldosteronism can be made by CT-scanner and the response of aldosterone to the posture test. Such a complex assessment leads to the identification of patients who can be surgically treated. This treatment consists in a unilateral adrenalectomy which can be realised by laparoscopy. [less ▲]

Phosphorus is mainly present in the serum as phosphate which is the principal intracellular anion, essential for the organism, in particular through its role in the production of ATP. In plasma, only inorganic phosphorus (Pi) is measured. In this article, we will review new information about the regulation of Pi at the intestinal, osseous and mainly renal levels. The various cotransporters sodium-phosphorus (Na-Pi) will also be examined and the molecular regulation mechanisms approached. Finally, illustration of Pi physiology will be given through various clinical examples. [less ▲]
