Filter by:To evaluate the dialysability of Dotarem®, after an IV injection of 0.1 mmol/kg in patients with chronic renal failure who require hemodialysis treatment.
T regulatory cells (T regs) are responsible for immune tolerance in solid organ transplant patients. This study will evaluate the treatment of children with kidney transplants either with Campath and other immune system suppressing medications alone or in combination with injection of autologous CD4+CD25+CD127lowFoxP3+ T regulatory cells expanded ex vivo. The aim of this study is to develop a new strategy that will be more effective in preventing organ rejection and maintaining patient health.
This is a prospective cross-over study including 10 stable hemodialysis patients with chronic kidney disease stage 5. The cross-over study lasts 2 weeks with the study dialysis sessions at midweek. During one session, the patient will be dialyzed during 4 hours with high volume post dilution hemodiafiltration (HDF) with an FX800 hemodialyzer (Fresenius Medical Care) and a blood flow of 300mL/min, dialysate flow of 500mL/min, and substitution flow of 75mL/min. During the other midweek session, the patient will be dialyzed during 8 hours with high flux hemodialysis (HD) with an FX80 hemodialyzer (Fresenius Medical Care) and a blood flow of 200mL/min and a dialysate flow of 500mL/min. The HDF and HD sessions will be randomized. Blood samples will be drawn pre and post dialysis from the arterial blood line, and after 30min after dialysis start, a blood sample will be drawn from the inlet and outlet line. At the dialysate outlet line, partial dialysate collection is performed at the outlet line. Blood and dialysate samples will be analyzed for a broad range of retention solutes like small and water soluble solutes, middle molecules, and protein bound solutes. These data will be further used to calculate solute removal and evaluate any differences between the solute removal during high volume post dilution HDF and high flux HD.
African Americans are less likely than Whites to receive kidney transplants, despite their being more than two-fold as likely as Whites to develop end stage renal disease (ESRD). Living related kidney donation (LD) offers patients an opportunity to bypass many barriers to receipt of deceased kidney transplants (e.g. waiting lists and immunological incompatibility), but minorities are less likely to receive living related kidney transplants (LRT). Evidence suggests African Americans may not discuss LD/LRT with their families or physicians at optimal rates, and thus may not have adequate information to initiate or participate in shared decision-making regarding LD/LRT. African Americans may also have financial concerns regarding convalescence and out of pocket expenses related to LD/LRT, another barrier impeding LD/LRT. The primary goals of this study are to overcome these important barriers by enhancing ethnic minorities' consideration of LD/LRT through the promotion of shared decision-making regarding LD/LRT and provision of financial assistance for out of pocket expenses. The investigators specific aims are: a) to develop culturally sensitive informational (audiovisual) and financial interventions and b) to perform a randomized controlled trial to assess their effectiveness in increasing pursuit of LD/LRT among African American patients with ESRD and their families. The investigators hypothesize: (1) Patients and families who view informational materials designed to promote shared decision-making regarding LD/LRT will be more likely than patients and families not viewing these materials to discuss LD/LRT with family and with health care professionals. Patients and families viewing such informational materials will also be more likely than those not viewing these materials to pursue and complete the LD/LRT process and (2) patients and their families who are offered the intervention to promote shared decision-making plus a financial assistance intervention for potential live kidney donors will be more likely than patients and families not offered both interventions to pursue and complete the LD/LRT process.
End-stage renal disease (ESRD) patients often develop cardiovascular complications, and cardiovascular disease is the leading cause of death in this population. Ranolazine's ability to treat angina without reducing heart rate or blood pressure makes it an important option for ESRD patients. The hemodialysis clearance of ranolazine is unknown. A single-dose pharmacokinetic study is needed to characterize ranolazine and its metabolites in ESRD patients on and off hemodialysis. Results of the proposed study will provide initial dosing estimates for a follow-up, multiple-dose pharmacokinetic study in this population.
Individuals with kidney disease are at a higher risk for heart and vascular diseases, including heart attacks and strokes, than those with normal kidney function. The purpose of this research study is to collect information on the causes, complications and treatment of kidney disease. Patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data will be collected to examine relationships between biochemical and genetic markers and cardiovascular risk. Information on the health history of incident hemodialysis and peritoneal dialysis patients will be captured using structured patient interviews and review of medical records. Blood and urine specimens will be collected at the time of dialysis initiation and stored in order to perform novel biochemical and genetic assays in the future. The overall goal of the CKDCS/LUCID study is improve understanding of cardiac-associated risks and to improve treatment in patients with kidney disease. A cardiac imaging substudy will be performed in a subset of patients enrolled. The goals of the substudy are to examine whether the risks of developing common cardiac-related complications (coronary artery calcification [CAC] and left ventricular hypertrophy [LVH]) are associated with certain medications taken by individuals on dialysis and whether these risks are modified by a genotypic predisposition.
The objective of this non-interventional study is to confirm that with standard OsvaRen® treatment it is possible to achieve in at least 60% of the patients the levels of phosphorus, total calcium, and iPTH seen in the CALMAG study also in the normal clinical practice.
Secondary hyperparathyroidism (sHPT) is common in patients with chronic kidney disease (CKD), including those who are undergoing long-term haemodialysis treatment. sHPT is characterized by persistently elevated levels of parathyroid hormone (PTH) and major disturbances in phosphorus and calcium metabolism. When glomerular filtration rate (GFR) falls, the phosphorus clearance decreases significantly, leading to phosphorus retention. The resulting hyperphosphatemia is thought to be one of the principal causes of secondary hyperparathyroidism which is a very early complication of patients with CKD. Its diagnosis and treatment is crucial in the management of such patients.The treatment of the sHPT of CKD's patient includes dietary phosphate restriction, the use of phosphate binders, correction of hypocalcaemia, the use of vitamin D and its derivatives. The calcimimetic agent cinacalcet hydrochloride may be also used in combination with vitamin D. While the majority of patients can be controlled in this way, medical therapy is not always successful in achieving adequate control of secondary hyperparathyroidism. Oral medications (calcimimetics, recently developed phosphate binders, and active vitamin D derivatives amount to very high monthly costs, and have efficacy limitations as well as side-effects. HIFU may become a valuable alternative treatment that help control secondary hyperparathyroidism in selected patients presenting with enlarged parathyroid gland(s) visible at ultrasonography,. The aim of this study is to evaluate the efficacy and safety of HIFU treatment in chronic haemodialysis patients with secondary hyperparathyroidism presenting with enlarged parathyroid gland(s) which are visible at ultrasonography and for whom medical therapy has been unsuccessful.
Our preliminary studies have demonstrated that an innovative new design of the hemodialysis venous needle (the needle that returns the cleaned blood from the hemodialysis filter to the patient) with three jets is superior to the standard venous needle because it decreases the velocity and turbulence of the blood when compared with the standard venous needle, it is more efficient in the removal of toxins from the blood, and it is safe and effective. More importantly, our preliminary studies suggested that the new needle causes less damage to the dialysis vascular access and to circulating blood cells and less inflammation and oxidative stress. These will decrease medical complications, the high cost of care and death in dialysis patients. The current study will corroborate the finding of previous studies.
In the United States, African Americans are 3.6 time and Hispanics 1.5 times more likely to suffer from chronic kidney disease and need dialysis treatment for life, when compared to the non-Hispanic Whites. Unfortunately many dialysis patients die, so that after 5 years only less than 35% are still alive. Dialysis patients who appear malnourished or who have muscle and fat wasting are even more likely to die. Interestingly, among dialysis patients, minorities (African Americans, Hispanics and Asian Americans) usually survive longer than the non-Hispanic Whites. If the investigators can discover the reasons for these so-called "racial survival disparities" of dialysis patients, the investigators may be able to improve survival for all dialysis patients and maybe even for many other people who suffer from other chronic diseases. During this 5 year study the investigators would like to test if a different nutrition and diet can explain better survival of minority dialysis patients. The investigators will also test if in additional to nutrition there are 2 other reasons for better survival of minority dialysis patients, namely differences in bone and minerals and differences in social and psychological and mental health. The investigators plan to study 450 hemodialysis patients every 6 months in several dialysis clinics in Los Angeles South Bay area. These subjects will include 30% African Americans, 30% Hispanics, 30% non-Hispanic Whites and 10% Asians. Every 6 months the investigators will examine their nutritional conditions, dietary intake, psycho-social conditions and quality of life, and will recruit 75 new subjects to replace those who left our study as a result of kidney transplantation, death or other reasons. Hence, the investigators estimate studying a total of 1,050 hemodialysis patients over 5 years. Clinical events such as hospital admissions and survival will be followed. Blood samples will be obtained every 6 months for measurements of hormones and "biomarkers", and the remainder of the blood will be stored in freezers for future measurements. The investigators plan to design and develop race and ethnicity specific nutritional risk scores and food questionnaires and will test some of these scores in larger national databases of hemodialysis patients. Almost a year after the study starts, the investigators also plan to do additional tests of body composition and dietary intake in a smaller group of these patients at the GCRC.
