Does Intravenous Iron Therapy Decrease Serum Phosphorous Levels?

Chronic Renal Failure

Intravenous iron therapy is common and effective, with few side effects. Two formulations are used, venofer or iron sucrose and ferrlecit, or ferric gluconate. The association between intravenous iron use and decrease in serum phosphorus and vitamin D levels, with increased fractional excretion of phosphorus, has been observed with older iron preparations, such as saccharated ferric oxide. However, hypophosphatemia and osteomalacia have been reported with iron carboxymaltose, a newer iron formulation. There is no information in the literature about phosphorus and vitamin D levels after treatment with venofer or ferrlecit. We intend to check phosphorus and vitamin D serum levels in our patients prior to and after treatment with these iron formulations.

Essential Nutrients in Critically Ill Patients With Severe AKI Treated With and Without CRRT

Acute Kidney Failure

The aim of this study is to measure plasma levels of essential vitamins, trace elements and amino acids in critically ill patients with severe AKI. In patients who are treated with continuous renal replacement therapy, we plan to evaluate whether there are any additional losses of nutrients into the filtrate.

Bariatric Surgery for Obese Patients With Chronic Renal Insufficiency

Chronic Kidney DiseaseObesity

The creatinine clearance will be measured using two consecutive 24 hour urine collections, with the objective of minimizing errors due to poor quality urine collection. The GFR will be measured by a reference method, because its estimation from blood creatinine levels (eGFR) by the MDRD study formula may be confounded by variations in muscle mass, and therefore creatinine production, following bariatric surgery. The method will remain the same in each center, and therefore consistent for any given patient, throughout the duration of the study. The GFR measurements will be performed after stopping any medication blocking the RAAS, and reducing diuretics for one week, with the introduction or increase of alpha-blockers or centrally-acting hypotensive agents. If it is impossible to stop RAAS-blockade (heart failure), the dose will at least be reduced for one week. This precaution is required to minimize the bias of functional renal insufficiency because the state of extracellular hydration is difficult to assess in obese subjects. Subsequent measurements of GFR will be performed in the same way. The choice of the tracer to measure GFR may vary according to study center. 51Cr-EDTA, 99Tc-DTPA, iohexol or inulin may all be utilized. Because the assessment of edema is hazardous in extremely obese patients and because kidney disease favors edema formation, the simplified single injection method and the determination of plasma clearance measurement of the tracer is not reliable . Only the constant infusion method will be used to measure GFR. Briefly, GFR will be determined by calculating the glomerular clearance (Cl) from plasma concentrations (P) and renal excretions per unit of time (UxV) during infusion at a constant plasma level of the tracer (Cl=UxV/P). The result will be given as mean value of several consecutive clearances. Because correct urine collection is key for the procedure, seven collection periods (instead of 5 usually) will be performed for the calculation of the mean clearance. Bladder catheterization will be used only when it can be anticipated that the patient will not void satisfactorily. In the last 30 consecutive patients with mGFR below 60 ml/min/1,73m2, this occurred twice and the subjects were 70 and 79 years old. Therefore, this might occur exceptionably in the study. Raw data from each center will be sent to the coordination center (Nice) to examine and validate the calculation of mean clearance values. To that aim, extreme and non-representative clearances will be excluded. At least 3 of the 7 periods will be taken into account to calculate the mean values. For instance, in the last 30 consecutive patients with mGFR below 60 ml/min/1,73m2, investigators considered on average 4.7 periods and obtained a mean non-indexed GFR value of 40,7 ± 2,5 ml/min. Primary assessment will be performed at one year, as a previous study has already suggested a significant benefit within this period [66], and because surgery can't be delayed further in these patients strongly expecting the intervention, but follow-up will be extended to three years or until the end of the study, in order to document whether the initial benefits of surgical intervention are maintained. A reduction in the absolute value of measured GFR (mGFR) following bariatric surgery is expected in the first six months after surgery (M0 - M6). However, the weight loss may allow an increased in mGFR indexed to body surface area up until M6, and above all towards M12. the investigators expect a subsequent stabilization of mGFR between M12 and M36 in the bariatric surgery group, and will seek to measure the anticipated reduction in mGFR in the control group who remain in a state of glomerular hyperfiltration. All relevant cardiovascular, metabolic and nutritional parameters necessary to study the risk/benefit ratio of the intervention will be analyzed. Primary: bariatric surgery slows the progression of chronic kidney disease in the obese. Secondary: bariatric surgery improves survival, cardiovascular prognosis, metabolic, nutritional and inflammatory parameters, quality of life, and access to transplantation in the sub-group of patients whose GFR < 20ml/min/1.73m2 at inclusion, and there could be a chance loss for the patients in delaying surgery by one year.

Low Sodium Dialysate and Ambulatory Blood Pressure Measurement Parameters

Chronic Renal FailureHypertension

End stage renal disease (ESRD) is related with increased cardiovascular mortality and morbidity. Hypertension (HT) is an important risk factor for cardiovascular disorder among hemodialysis (HD) patients. The aim of this study going to investigate the effectivity of low-sodium dialysate on the systolic and diastolic blood pressure (BP) levels detected by ABPM and interdialytic weight gain (IDWG) in patients undergoing sustained hemodialysis treatment. Methods: The study will be included 46 patients who had creatinine clearance levels less than 10 ml/min/1.73 m2 and had been on chronic HD treatment for at least one year. After the enrollment stage, the patients will be allocated low-sodium dialysate or standard-sodium dialysate for six months via computer-generated randomization.

Novel Biomarkers for Risk Prediction of Contrast-Induced Acute Kidney Injury Post Coronary Angiography...

Acute Kidney InjuryRenal Insufficiency1 more

Contrast-induced acute kidney injury (CI-AKI) has been recognized as the third most common cause of hospital acquired AKI, after hypotension-associated hypo-perfusion and post-operative AKI. The development of CI-AKI after cardiac catheterization is associated with a significant increase in both short-term and long-term mortality and morbidities, as well as an increase in length of stay and cost. The only marker of renal function that has predictive ability is creatinine and it has significant limitations in identifying patients who will develop AKI. Therefore, a diagnostic test for predicting CI-AKI risk would have widespread clinical utility. The primary purpose of this study is to measure the association between baseline expression of senescence markers in blood using SenesceTest and the occurrence of CI-AKI post cardiac catheterization.
