Study to Evaluate the Prospective Payment System
Chronic Kidney DiseaseTo describe trends in treatment patterns of Small Dialysis Organizations (SDOs) prior to and during the implementation of the Centers for Medicare and Medicaid Services' (CMS') policy [End Stage Renal Disease (ESRD) Prospective Payment System (PPS)] to bundle reimbursement for all dialysis services. Specifically, to describe CMS ESRD PPS quality performance measures for dialysis centers over time.
Chronic Kidney Disease in Teenagers With Congenital Cardiac Disease
Chronic Kidney FailureCongenital Heart DefectsThe prevalence of chronic kidney injury (CKD) following cardiac surgery during childhood is not known, but there is evidence of CKD in young adults. In the present study assumption is made that CKD can already by diagnosed in patients at or just before adolescence, and the aim is calculate its prevalence according to the KDIGO criteria by a cross-sectional study, which will enroll patients aged 10 to 15 years. The second hypothesis is that events occurring peri-operatively during initial surgery or during follow-up could by chart review and regression analysis.
Dyslipidemia-related Risk Factors in Dialysis
Chronic Renal DiseaseCardiovascular Disease1 moreIn this study, we studied lipoprotein abnormalities-related variables as risk factors for the development of cardiovascular disease in patients on renal replacement therapies.We studied 96 dialyzed patients, 62 males and 34 females, on mean age 62.1 years old and 24 healthy controls.We concluded that metabolic acidosis activating the inflammation and lipoprotein oxidation influences the dyslipidemia and cardiovascular morbidity of patients on renal replacement therapies.Dialysis adequacy was positively associated to cardioprotective HDL.Peritoneal dialysis holds a better acidosis level and lower oxidized lipids than hemodialysis modalities.
Triglyceride/High-density Lipoprotein Cholesterol Ratio in Chronic Kidney Disease
Chronic Kidney DiseaseThe Triglycerides (TG) to High Density Lipoprotein Cholesterol (HDL-C) ratio is a feature of insulin resistance and an independent predictor of cardiovascular risk. The investigators aimed to evaluate the relationship between TG/HDL-C ratio and the endothelial functions in patients with CKD.
Pulsed Perfusion for Marginal Kidneys
Chronic Kidney DiseaseTrends in organ donor pool are characterized by an increasing age and a shift towards cerebrovascular diseases as primary causes of death. As a result, donors older than 60 years nowadays represent more than one fourth of the entire donor pool in Italy. This, along with an increasing number of patients on the waiting list for transplantation, prompted a growing use of organs from subjects older than 60 years that would have been considered unsuitable years ago. To improve graft outcomes, transplant of two older kidneys in the same recipient has been proposed. To optimize allocation of these organs to single or dual transplantation,a scoring system for kidneys, based on biopsy, with scores ranging from a minimum of 0 (indicating the absence of renal lesions) to a maximum of 12 (indicating the presence of marked changes in the renal parenchyma) has been suggested. According to this panel, kidneys with a score of 4 or lower are predicted to contain enough viable nephrons to be used as single transplants, those with a score of 5, 6, or 7 can be used as dual transplants, kidneys with a score greater than 7 are discarded. The survival of kidney grafts obtained from donors older than 60 years and allocated for single or dual transplantation on the basis of biopsy findings before transplantation was similar to that of single grafts from younger donors. To further improve these results, set-up of strategies to preserve organs is crucial to save the residual nephron mass and optimize outcomes of these marginal grafts. In this regard, over the past 30 years two methods of kidney preservation have been developed. With cold storage, the kidney is flushed once it is removed from the donor and placed in an ice-cooled container with preservation solution. With the use of pulsatile machine perfusion, the kidney is connected to a machine, which pumps a cold solution containing oxygen and nutrients through the kidney. This process allows for metabolism to continue in the kidney with end products being removed. The broad aim of the present study is to evaluate whether pulsatile machine perfusion of kidneys from older/marginal donors may provide better outcomes than static perfusion. To this purpose the outcome of recipients of perfused kidneys will be compared with the outcome of historical controls receiving non-perfused kidney selected and allocated on the basis of the same criteria and matched by gender, age and kidney histologic score.
Survey on Anemia Therapy in Participants With Chronic Kidney Disease (CKD) Not on Dialysis
Chronic Kidney DiseasesThis study is a prospective, non-interventional, cross-sectional multicenter survey. The aim is to better understand the current therapy pattern for anemia in CKD treated with erythropoiesis-stimulating agents (ESAs) and not on-dialysis participant population in Israel. Participating physicians will be requested to interview eligible participants with CKD not on dialysis and to complete for them a satisfaction survey for anemia treatment. The survey will be completed twice, once at study start and once at six months' follow-up.
Immunologic Abnormalities, Chronic Inflammation and Oxidative Stress in Chronic Kidney Disease
Chronic Kidney DiseaseThe common causes of mortality are late stages of chronic kidney disease, cardiovascular disease and infections, are associated with abnormalities of the immune system, an underlying state of chronic inflammation and oxidative stress. These processes have not been carefully described in the chronic kidney disease population. The researcher can use Diffuse Optical Spectroscopy to determine the immune system in individuals with chronic kidney disease and describe the association with chronic inflammation and oxidative stress in that population.
Mineral and Bone Disorders Outcomes in Stage 5D of Chronic Kidney Disease
End Stage Renal DiseaseHyperparathyroidism1 moreThe MBD-5D is a prospective observational study with a case-cohort and a cohort design. Eligible patients are receiving hemodialysis and have secondary hyperparathyroidism. The study's three goals are (1) to record the patients' characteristics, and variation in the patterns of their treatment; (2) to analyze factors associated with variation in those medical practice patterns; and (3) to identify practice patterns and other factors that affect hospitalization, mortality, and other patient-level outcomes.
Urinary Concentration and Diluting Ability in Patients With Chronic Renal Disease and/ or Hypertension...
Renal InsufficiencyChronic1 moreThe investigators want to test the hypothesis that patients with chronic renal disease have a poorer ability to preserve water after being thirsty and a poorer ability to excrete water after a load of fluid. They presume that these abilities become poorer when renal insufficiency progresses. The investigators further hypothesize that patients with hypertension also have a decreased ability to concentrate and dilute urine.
