Active clinical trials for "Renal Insufficiency, Chronic"

This study is to assess the effect of 48 weeks administration of Renamezin capsule on prevention of sarcopenia in pre-dialysis patients with chronic kidney disease.

Double blinded, randomized controlled trial evaluating medium cut-off dialyzer compared to high flux dialyzer in ironic hemodialysis patients over a 6 months period with 3 months crossovers.

Obesity is associated with glomerular hyperfiltration leading to renal impairment and is a risk factor for the progression of kidney disease.Weight loss can reduce proteinuria and improve eGFR.Intermittent fasting is safe and effective, and in addition to improving body shape and weight in obese patients, it can also improve glucolipid metabolism, reduce proteinuria, improve kidney function and delay the progression of kidney disease.

The objective of this unblinded study is to assess the nutritional effects of a 12 weeks administration of the specific enteral nutrition (SEN) RealDiet®Renal pockets, as well as the impact on the patients' quality of life.

The purpose of this study is to learn more about how the kidneys control the blood levels of phosphorus in patients with early chronic kidney disease. The ultimate goal is to use this information to design improved treatment strategies for phosphorus-related problems for the millions of patients with chronic kidney disease.

The purpose of the study is to demonstrate the safety and immunogenicity of a new investigational hepatitis B virus vaccine, HEPLISAV-B, in patients 18 to 75 years of age who have progressive loss of kidney function.

Subjects with normal kidney function are able to excrete in their urine the calcium and phosphorus absorbed via the gastrointestinal tract and are thereby are able to maintain calcium and phosphorus balance. Patients with chronic kidney disease often have normal blood levels of calcium and phosphorus but no research has been conducted to determine if they are able to excrete their daily intake of these minerals. If they are not able to excrete their daily intake, these minerals could be deposited in soft tissue and blood vessels and contribute to the increased risk of cardiovascular disease seen in patients with chronic kidney disease. This study will determine if subjects with chronic kidney disease are in balance primarily with regard to calcium and at what level of kidney function they are no longer able to maintain balance. Understanding whether patients with chronic kidney disease are in balance will help direct future therapeutic interventions.

In this prospective study, the investigators aimed to evaluate the effects of improved hyperuricemia, a minor cardiovascular risk factor, on endothelial dysfunction in patients with chronic kidney disease.

This study will evaluate whether earlier intervention with vitamin D in stage II/III chronic kidney disease will prevent or delay secondary hyperparathyroidism. Subjects will receive vitamin D or placebo at study entry and will be followed for a period of one year. The hypothesis is that subjects given vitamin D will have lower PTH and higher 25(OH)D after 1 year compared to placebo. Additionally, there will be less subjects who progress into secondary hyperparathyroidism in the vitamin D treated group compared to the placebo treated group.

Patients with chronic kidney disease (CKD) have a higher mortality rate than the general population, with cardiovascular disease (CVD) accounting for approximately 50% of deaths. Vascular calcification is a common finding in patients with CKD. Furthermore, patients with CKD develop secondary hyperparathyroidism, partly because of a decrease of calcitriol synthesis on the kidney. Treatment of secondary hyperparathyroidism includes use of activated vitamin D including calcitriol and paricalcitol. Recent evidence in dialysis patients suggest an improved survival in patients using paricalcitol compared to calcitriol. Studies in uremic rats suggests that there are differential effects of calcitriol and paricalcitol in expression of markers of soft-tissue calcification independent of calcium-phosphorus product. Calcitriol increased calcification of vascular smooth muscle cells cultured in calcification media. There was also significant increase in pulse pressure in animals treated with calcitriol. The investigators hypothesize that these different forms of vitamin D may have differential effects in vascular calcification progression in CKD patients.
