Cognitive Impairment in Kidney Disease

Kidney InsufficiencyChronic

An increasing number of Veterans are anticipated to develop chronic kidney disease (CKD) and require hemodialysis (HD) treatments as the Veteran population ages. In 2003, approximately 290,000 US citizens were receiving HD and an estimated 19 million were affected by CKD. The annual growth rate is predicted to be 7% per year with 500,000 Americans receiving HD treatment by 2010. In 2005, approximately 2500 Veterans were receiving HD with growth expected to parallel that seen in the general population. Whereas Alzheimer's disease is the leading cause of dementia in the general population, growing evidence suggests that patients with advanced CKD experience cognitive deficits related to accelerated cerebrovascular disease. Patients with advanced CKD have been shown to have a high prevalence of sub-clinical cerebrovascular damage on imaging studies and a heavy burden of vascular risk factors such as diabetes, elevated cholesterol, and hypertension. Many of the cognitive deficits related to cerebrovascular disease may go unrecognized by routine measures of cognition. HD patients have increased number of hospitalizations, and several compliance issues ranging from congestive heart failure to dangerous electrolyte imbalances. Impaired cognition in this population is likely to have a significant impact on self-care and compliance with complex medical regimens. Currently, the severity and scope of cognitive impairment related to vascular disease is not well known in patients with advanced kidney disease. Additionally, the relationship between cognitive impairment and measures of self-care independence are not well known. Loss of independence and function secondary to impaired cognitive function is likely to be a significant problem for patients with advanced kidney disease. Early identification of functional impairment, particularly instrumental activities of daily living (IADL), will allow for rehabilitation intervention. Maintaining or improving functional independence through intensive rehabilitation could translate into better compliance and lower hospitalization rate among HD patients. Information obtained from this study is likely to heighten awareness of cognitive impairment and the functional consequences in Veterans with advanced kidney disease. Primary objectives are to determine: The range of cognitive deficits with emphasis on domains affected by vascular disease in patients with advanced CKD and those receiving hemodialysis. The associations between severity of cognitive impairment and severity of kidney disease. The prevalence of impaired IADLs and the level of health-related quality of life (HRQOL) in patients with advanced CKD and those requiring hemodialysis. The relationship or association of cognitive impairment with IADL and HRQOL. Secondary objective is to determine: 1. The relationships among cerebral and carotid blood flow, carotid artery stiffness, and renal specific metabolic abnormalities with cognitive impairment.

Daptomycin Study - Collection of Pharmacokinetic Samples in Patients With Renal Failure

Renal Failure

This will be a prospective, multicenter, open-labeled, non-comparative pharmacokinetic study conducted in 10 critically ill, anuric patients receiving CVVHDF. Enrollment will take place at 3-5 clinical sites in the United States. A study coordinator at each site will be identified and institutional specific processes (e.g., pharmacy records, etc.) will be utilized to identify patients. Full evaluation of inclusion and exclusion criteria will be conducted by each site's coordinator within 48 hours of initiation of daptomycin therapy. Subjects receiving daptomycin 6mg/kg (total body weight) once daily for a suspected/documented infection, as deemed necessary by the treating clinician will be screened for inclusion in the current study. Dialysate, ultrafiltrate, and blood flow rate utilized during the CVVHDF procedure will be determined by clinicians at discretion to optimize stability of patients. Daptomycin samples will be obtained around the third dose in an attempt to achieve approximate steady-state concentrations. Pre- and post-filter blood samples will be collected simultaneously with dialysate and ultrafiltrate specimens at multiple time points. Protein binding will be assessed by filtration of the serum samples at the peak drug concentration time points.

Resistive Index Measurements After Kidney Transplantation

Kidney Failure

The purpose of this study is to evaluate the prognostic performance of intrarenal resistive index in the first years after kidney transplantation on graft function and on patient and graft survival. In addition, the determinants of the intrarenal resistive index, including a detailed analysis of the relation between graft histology and the intrarenal resistive index, will be assessed.

Kidney DiseaseKidney Failure1 more

This study is a multicenter, non-randomized, retrospective study to collect long term (5 years post-transplant) clinical outcome data to test whether the results of the noninvasive immune monitoring test strategy performed in the parent study (CTOT-01, NCT00308802) in first six-month post-transplant is predictive of 5-year outcomes. Each center will complete a retrospective chart review for the data on patient survival, graft survival and renal function.

Risk of Central Venous Stenosis in Patients With Chronic Renal Failure After IJ Line Placement

Thrombosis

The purpose of this study is to compare the difference in thrombosis as a result of internal jugular (IJ) catheters versus peripherally inserted central catheter (PICC) lines. It is hypothesized that there will be a decreased rate of thrombosis in patients as a result of IJ catheters verses PICC lines.

Impact of Physical Activity on Patients With Chronic Kidney Disease Not Receiving Dialysis Followed...

Renal InsufficiencyChronic

PHYSALYS is an observational multicenter study. It's an analytical study comparing 2 groups: patients exposed to physical activity and unexposed. The main objective of the study is to compare the evolution of glomerular filtration rate at inclusion and 12 months later between patients practicing physical activity and patients not practicing. If necessary, the renal disease-related complications, which are not influenced by physical activity: (type of kidney disease, age and tobacco), would be taken into account. TIRCEL patients with chronic kidney disease (CKD) at stages 3, 4 or 5 can be included in the study. Their serum creatinine data, 12 months prior to inclusion, is collected retrospectively. Patients are followed in the trial during 12 months. To evaluate physical activity, patients respond to Global Physical Activity Questionnaire 2 (GPAQ2) at inclusion and 12 months later. During this 12 months period, the same biological data are collected prospectively.

Screening for Patients Needing Kidney, Kidney-Pancreas, or Islet-Cell Transplant

Diabetes MellitusKidney Failure

Kidney transplantation is the preferred treatment for most end-stage kidney disease. This procedure is limited, however, by two major factors: 1) a shortage of donor organs and 2) organ rejection by the recipient. The National Institute of Diabetes and Digestive and Kidney Diseases is screening patients with kidney failure or diabetes who may be eligible for kidney, kidney and pancreas, or islet cell transplantation. Patients in this screening study are not offered treatment. When the screening is complete, patients will be offered an opportunity to participate in another institute study, or, if there are no active studies appropriate for the patient, other options will be suggested to the primary or referring physician. Patients found eligible for a study are not obligated to participate. Screening for all patients typically consists of blood tests, urinalysis, electrocardiogram, PPD tuberculosis screen and pregnancy test. Chest and kidney X-rays and other studies may be done on patients determined eligible for a particular study, including transplantation. A summary of all test results will be sent to the referring physician unless the patient requests otherwise. ...

The Early Administration of Sodium Thiosulfate Should Help to Reduce the Mortality of Dialysis Patients...

CalciphylaxisRenal Insufficiency1 more

The national drug safety agency authorizes nominatively the use of sodium thiosulfate in dialysis patients with calciphylaxis. To date, it is the largest global cohort (more 600 patients from 2012 to 2016). We wanted to study retrospectively the fate of these patients at 6 months including mortality. Early use improves effectiveness.
