Active clinical trials for "Renal Insufficiency"

Intestinal microbiota has recently emerged as an important player in the progression and complications of chronic kidney disease(CKD). And drug therapy which selects the gut as a target has raised lots of concern. It has been reported that the composition of intestinal flora has changed in uremic patients. Specifically, imbalanced ecosystem has higher number of pathogens such as Clostridia, Enterobacteria,and lower number of beneficial microbes such as Lactobacilli and Bifidobacteria. This modification of intestinal flora can strongly increase transformation of amino acids into Uremic Retention solutes, e.g., indoxyl-sulfate (IS), p-cresyl sulfate (PCS), which are so called gut-derived uremic toxins. The dysbiosis also contributes to an increase in intestinal permeability by disrupting the colonic epithelial tight junction,which may subsequently lead to translocation of endotoxin and bacteria into the host's internal environment,resulting in systemic micro-inflammation.Also all of these can promote the progression of renal failure and the incidence of cardiovascular complications,renal osteodystrophy and anemia.Probiotics is defined by the World Health Organization as 'live microorganisms that, when administered in adequate amounts, confer a health benefit on the host'. Probiotics are being increasingly used for various pathologic conditions.It is said that probiotics have a therapeutic role in maintaining a metabolically balanced gastrointestinal tract (GIT).And in our previous study,the investigators found that in uremic rats,lactobacillus acidophilus can relieve bacterial translocation and decrease the level of inflammatory markers.So our study is mainly designed to investigate whether probiotics can modulate the balance of intestinal ecosystem, prevent the bacterial translocation from gut and alleviate the systemic inflammation in hemodialysis(HD) patients.

It is estimated that in the United States there are approximately 8 million individuals who have moderate to severe chronic kidney disease (CKD). Among them hypertension is common and is often poorly controlled due to an expanded volume state; diuretics are frequently prescribed. Loop diuretics are potent and effective in lowering blood pressure (BP) but their use is associated with acute kidney injury. Thiazide diuretics, on the other hand, are less potent, their use may be associated with less acute kidney injury, but as yet there are no firm data to support that thiazide diuretic therapy can improve BP among subjects with advanced CKD. The investigators found 13 studies on the use of thiazide diuretics in advanced CKD either alone or in combination with loop diuretics and concluded that thiazides may be useful. Thiazides cause a negative Na balance, increase Na excretion by 10-15% and weight loss by 1-2 kg in observational studies. Observational data show that thiazides lead to an improvement in seated clinic BP of about 10-15 mmHg systolic and 5-10 mmHg diastolic whereas randomized trials show about a 15 mmHg reduction in mean BP. Randomized trials had only between 7 and 23 subjects each; accordingly, larger studies are needed to evaluate their safety and efficacy in moderate to advanced CKD.

MK-2060 is being developed for prevention of thrombotic complications in end-stage renal disease (ESRD). The purpose of this study is to conduct a preliminary evaluation of the safety and tolerability of MK-2060 treatment in combination with a commonly used P2Y12 receptor inhibitor, clopidogrel, in ESRD patients.

The primary objectives of this study are: To obtain information on the pharmacokinetics of cytisinicline following a single oral dose in subjects with varying degrees of renal impairment relative to matched controls with normal renal function. To investigate the extent of cytisinicline removal by hemodialysis.

This study is open to adults aged 18 years and older. People without kidney problems and people who have moderate or severe kidney problems can join the study. The purpose of this study is to find out how a medicine called BI 1015550 is taken up in the blood of people with and without kidney problems. Kidney problems may change how a medicine is taken up in the blood. All participants take a single tablet of BI 1015550. Participants are in the study for about 2 weeks. During this time, they visit the study site 6 times. On the second visit, participants stay overnight at the study site for 4 nights. At the visits, doctors take blood samples to measure the levels of BI 1015550 in participants' blood. Then they compare the results between the groups of participants with and without kidney problems. The doctors also check participants' health and take note of any unwanted effects.

This study will evaluate the pharmacokinetics (PK), safety, and tolerability of a single oral dose of zibotentan in patients with moderate hepatic and moderate renal impairment in comparison to a matched healthy control group.

This study is a randomized, multi-center，crossover study of a domestic FM peritoneal dialysis machine and Baxter HOMECHOICE.It aims to verify safety, effectiveness and manipulability of a domestic peritoneal dialysis machine.

Acute kidney injury (AKI) is a common complication after cardiac surgery. Mismatch in renal oxygen demand-supply may be an important pathogenetic factor. Levosimendan has been shown to improve renal blood flow, glomerular filtration rate and renal oxygenation in healthy controls after cardiac surgery. In order to investigate the effect of levosimendan in patients with AKI after cardiac surgery, the investigators plan a randomized placebo controlled trial. 30 patients will receive levosimendan or placebo. Renal blood flow and filtration fraction will be measured using infusion clearance technique of para-aminohippuric acid and Chromium ethylenediaminetetraacetic acid (Cr-EDTA) respectively.

The objective of this study is to compare the pharmacokinetics of ASP015K in patients with impaired renal function and subjects with normal renal function.

The purpose of this study is to evaluate the pharmacokinetics of a single dose of intranasally administered esketamine in participants with impaired renal function when compared to participants with normal renal function.
