Vitamin D is not seen anymore only as a phosphocalcic and bone hormone, but also as having an effect on global health (anti-infective, anti-inflammatory, anti-tumour roles and cardiovascular protection). Until recently, vitamin D repletion was defined as the minimal concentration that enables the prevention of rickets in children and osteomalacia in adults, i.e, approximately 8 ng/mL (20 nmol/L). However, most of the international experts agree to set minimal threshold of 25 OH vitamin D serum concentration, higher than the one previously admitted, with a limit of 20 ng/mL (50 nmol/L) to define a vitamin D deficiency and a limit of 30 ng/mL (75 nmol/L) to define vitamin D insufficiency. Recommendations for Vit D supplementation in healthy children were updated in France in 2012. The invariable supplementation of infants and toddlers is efficient since deficiency-related rickets have almost disappeared; however there is very few information in ill children populations. Vit D supplementation tolerance is usually considered as good and over-dosage risks are low, however these studies were conducted more than 30 years ago, and as far as we know, there is no study about calcium urinary excretion kinetics after intake of a 100 000 IU vial of cholecalciferol (Uvedose®). When 25 OH vitamin D serum concentrations exceeds 200 ng/mL, which is very rare in daily practice, toxic effects of Vit D may theoretically be observed, particularly hypercalcemia and hypercalciuria. Vitamin D deficit is very common in children with chronic kidney disease (CKD) with a 50 to 92% prevalence depending on the studies; it it is a risk factor for secondary hyperparathyroidism. Although international guidelines regarding the care of CKD children recommend 25 OH vitamin D serum concentrations over 75 nmol/L, there are no practical recommendations in terms of dose and frequency of native Vit D treatment. Therefore, the objectives of the present study has are the following: - to validate prospectively the efficacy of our service usual care for Vit D supplementation of children and adolescents seen in the paediatric nephrology department. - and to study the effect of Vit D supplementation (100 000 IU vial of cholecalciferol) on calciuria in these patients.
This observational, multi-center, open-label, prospective study will evaluate the relationship between serum interleukin-6 (IL-6) and C-reactive protein (CRP) levels and methoxy polyethylene glycol-epoetin beta dosage in participants with chronic kidney disease (CKD) on dialysis. Participants will be recruited who are on stable methoxy polyethylene glycol-epoetin beta maintenance therapy or will initiate therapy with methoxy polyethylene glycol-epoetin beta.
This study is a prospective, non-interventional, cross-sectional multicenter survey. The aim is to better understand the current therapy pattern for anemia in chronic kidney disease (CKD) treated with erythropoiesis-stimulating agents (ESAs) and not on-dialysis patient population in Israel. Participating physicians will be requested to complete a satisfaction survey for anemia treatment for eligible patients with CKD not on dialysis. The survey will be completed twice, once at study start and once at six months' follow-up.
The purpose of this study is to compare the effect of lanthanum carbonate and calcium carbonate on the progression of coronary calcification and vascular endothelial dysfunction.
Patients with end-stage renal disease (ESRD) have a high prevalence of impaired glucose metabolism. The pathophysiological cause is uncertain, but disturbances in the secretion, elimination and effect of glucagon, insulin and the two incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), probably play important roles. Our research group has previously found that dialysis patients without type 2 diabetes mellitus (T2DM) have a reduced incretin effect and an inability to suppress glucagon after a meal - two early pathophysiological characteristics of patients with T2DM and normal kidney function. The aim of the project is to provide a detailed description of the mechanisms underlying the (patho)physiological effects of the incretin hormones in patients with ESRD. We plan to investigate the above mentioned disturbances during fasting and hyperglycaemic conditions using incretin infusions during glucose clamping. Furthermore, stable isotopic tracers will be used to determine the effect of the incretin hormones on the endogenous glucose handling. We hypothesise that the effects of the incretin hormones in ESRD will be reduced in respect to healthy control subjects.
The prevalence of diabetes mellitus (DM) is increasing worldwide, suggesting that 45% of diabetics are undiagnosed. DM induces a kidney disease called diabetic nephropathy (DN) which is the largest single cause of end-stage renal disease and dialysis requirement. In South America the prevalence of DM and chronic kidney disease has increased, and great disparity exists among countries in regards to access to the dialysis treatment. It has been considerate that Hispanic origin increases the risk for DM. The South Americans have distinctive habits, culture, environment, behavior and genetic background and the factors involved in DN have not been defined yet. The early kidney lesions such as neoangiogenesis (pathologic generation of the new blood vessels) and extracellular matrix expansion have been described. The vascular endothelial growth factor A (VEGF) has been linked to angiogenesis, but the role of VEGF in DN has not been elucidated yet. VEGF signals mainly through VEGF receptor 2 (VEGFR2). VEGFR2 interacts with alphaV beta3 integrin (AVB3) in kidney. Additionally tenascin C is expressed in the extracellular matrix. Tenascin C and the tenascin C/AVB3 complex have also been linked to angiogenesis, however their roles have not been unveiled yet in the DN. Investigators hypothesize that VEGF signaling and tenascin C play an important role in DN and that VEGFR2, AVB3 and tenascin C interact. The purposes of this study is to characterize social, environmental and biological factors implicated in the DN in Ecuador and define the role of VEGF signaling and tenascin C in the pathogenesis of the DN. Investigators propose to study factors involved in DN in diabetic and non-diabetic adults from general population, with and without DN. In a single time investigators will evaluate demographics data, habits, personal and family history through a survey. Investigators will measure anthropometrics parameters and blood pressure; investigators will quantify blood glucose, glycosylated hemoglobin A1c and proteinuria. In addition investigators will examine the role of tenascin C and VEGF signaling by analyzing paraffin embedded kidney tissue, plasma and urine samples. Characterizing the factors involved in the DN from Hispanic people is key to establish adequate strategies of prevention, diagnosis and treatment in this population. Furthermore elucidating the role of proteins involved in DN may offer valuable tools for the development of new treatments.
The investigators developed iChoose Kidney -- a shared decision-making support tool accessible through iPad, iPhone, or the web -- to provide ESRD patients and their providers with a simple, standardized, easily accessible, statistically robust tool for use in the clinic to guide patient education and healthcare decision-making about treatment options of dialysis or kidney transplantation. The iChoose Kidney decision aid provides patients with estimates of their individualized 1 and 3-year risks of mortality on dialysis vs. transplantation, based on previous national data. The tool has the potential to improve communication and decision-making between patients and their healthcare providers and improve access to kidney transplantation among patients with ESRD. This will be a two-arm, randomized study, and will be conducted at 3 large transplant centers with diverse patient populations. One group of patients will receive standard education alone during their scheduled transplant evaluation. The second group will receive the standard education as well have the provider use the iChoose Kidney aid with them. The project timeline will be a total of 24 months inclusive of enrollment, follow-up, data analysis, and outcome evaluation. This study will assess how well the iChoose decision aid works in improving patient knowledge, preferences for treatment, and patient access to transplant. The study will also assess whether providers find the tool useful for providing ways to share information with patients about ways to treat their kidney disease.
In this genomic medicine implementation pilot project, the investigators aim to conduct a randomized trial in a network of community health centers and primary care facilities to study processes, effects and challenges of incorporating information for apolipoprotein L1 (APOL1)-attributable genetic risk for end stage kidney disease in patients of African ancestry with hypertension .
Although post-op renal function decrease is determined by serum creatinine, serum creatinine has disadvantages that it increases a long time after renal function decrease and it has various increasing time based on the level of renal function. Neutrophil Gelatinase-associated Lipocalin (NGAL's) usefulness as an evidence for acute kidney damage occurring from post-op cardiac surgery, being critical patients and contrast medium use is already proven. But NGAL's usefulness for renal function after non-cardiac surgery is not proven and especially, NGAL's usefulness for renal injury after non-cardiac surgery in chronic renal disease patients is not proven.Therefore, the investigators will study about renal function decrease after non-cardiac surgery with NGAL and serum creatinine.
