Active clinical trials for "Kidney Failure, Chronic"

The purpose of this study is to test whether a dialyzer with a higher than usual permeability for proteins can eliminate proinflammatory proteins from the blood of patients on regular maintenance hemodialysis who have chronically elevated levels of inflammation markers such as C-reactive protein (CRP) in their blood.

Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.

This study will investigate how the levels of a single dose of CTAP101 changes in the body over time (pharmacokinetics, PK) and how CTAP101 affects other mineral and hormonal balances (pharmacodynamics, PD) in patients with Stage 3 or 4 chronic kidney disease (CKD) with vitamin D insufficiency and secondary hyperparathyroidism (SHPT).

Patients with chronic kidney disease and end stage renal disease have greater cardiovascular risk than the general population. Vitamin D analogues have been shown in observational studies to have mortality benefit for these patients. This study is designed to investigate doxercalciferol's effect on the vasculature (i.e. endothelial cell function) as a possible mechanism to explain the mortality benefit.

Open-label, randomized study of NESP in pediatric subjects 18 years of age or younger. Subjects will receive study drug (NESP or rHuEPO) for 28 weeks after a 2 week screening and baseline period. During the study, procedures include bloodwork for laboratory assessments and vital signs. Dose titration determined by hemoglobin values taken weekly during the study. Antibody samples taken at baseline and during the end of study assessments. A physical examination and laboratory tests will conclude the study.

The investigators hypothesize that an increase in the duration of dialysis session in thrice weekly center hemodialysis may provide better outcome, less morbidity, higher quality of life, lesser requirement of medications, and lower total cost.

This single arm study will assess the efficacy and safety of PEGASYS in patients with chronic hepatitis C and end-stage renal disease, including patients on hemodialysis. Patients will receive PEGASYS at a dose of 180 micrograms weekly; those with a calculated glomerular filtration rate of <15mL/min will receive a reduced dose of 135 micrograms weekly. Following 48 weeks of treatment there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

As the influence of type of dialysis on survival of end stage renal disease (ESRD) patients remains unanswered, the present study is designed (randomized, prospective, multicenter, interventional) to assess clinical outcomes, and compare mortality, morbidity, Quality of Life (QOL) and cost effectiveness between maintenance In-center Hemodialysis (ICHD) and Continuous Ambulatory Peritoneal dialysis (CAPD). These data will ultimately bring clarity on whether or not any difference in patient survival exists between the two modalities. In order to test the feasibility of patients' willingness to be randomized to two different modality groups and retained in the randomized group, a pilot study is planned before the conduct of a main study. This pilot study comprises of a 6 months study, plus a 6 months observation if there is possibility to switch the patients into the main study. All ESRD patients requiring dialysis treatment within 8 weeks after a pre-study visit will be recorded in each site. Patients who provide written inform consent for collecting relevant information will be screened using certain inclusion/exclusion criteria. Eligible patients will undergo a standardized education regarding ESRD and treatment options. Thereafter the patient will be required to provide a second inform consent allowing for randomization and entrance into the study. Eligible patient will be randomized to either PD or HD treatment. The patients will be followed for a period of 6 months, during which patients will be treated with PD or HD as prescribed at each site, while meeting the dialysis adequacy and other indicators. For the first 3 months monthly visits are required, after which an every 3 months visit is planned. In this pilot study, the main objective is to assess the willingness of ESRD patients to be randomized to either PD or HD treatment; thereby determining if an adequate number of eligible patients can be recruited for a future large-scale study.

This 2 x 2 sequential factorial study evaluates two potential improvements to the standard immunosuppression regimen used at the investigators' institution to prevent rejection of transplanted kidneys. These two potential improvements are each applied in sequence to half of the study patients, creating 4 study arms; the other half receive the standard treatment. The two potential improvements are: Administering the immunosuppression induction agent rATG ("rabbit anti-thymocyte globulin") in a single dose at the time of transplantation, instead of in the usual series of 4 smaller doses over 6 days. After 6 months, modifying the maintenance immunosuppression used to prevent rejection by replacing the drug tacrolimus with mycophenolate mofetil (MMF). The two interventions, spaced sequentially six months apart, enable independent analysis of the two treatments so long as it can be shown that there is no synergistic interaction between them.

This study is seeking to identify the most effective strategy to manage pain, sexual dysfunction, and depression in patients receiving chronic hemodialysis therapy.
