Active clinical trials for "Renal Insufficiency, Chronic"

The purpose of this study is to determine whether a supervised resistance exercise training during hemodialysis is effective to increase physical activity in daily life in patients with end stage renal disease.

Chronic kidney disease is a renal injury and progressive and irreversible loss of kidney function and in its most advanced stage is called chronic renal failure. Although hemodialysis replace some kidney function, patients suffer some alterations characterized by "uremic syndrome" typically expressed by: motor neuropathy and/or autonomic neuropathy, cardiac or musculoskeletal myopathies, peripheral vascular changes, among others. Thereby, the the adoption of physical exercise should be encouraged. However, it is known that the ability to exercise the subject in hemodialysis is low and keeping in mind the weakness of the muscular system in these individuals, the aim of this study is to assess the effects of functional electrical stimulation (FES) on muscle architecture of patients with chronic kidney disease hemodialysis. For this the following assessments will be performed before and after stimulation: ultrasonography to assess muscle architecture; six-minute walk test to functional capacity; Kidney Disease and Quality of Life - Short Form questionnaire for quality of life; sit and stand test for resistance of the lower limbs; dynamometric by load cell for muscle strength of the lower limbs; flow-mediated dilatation to endothelial function; blood collection for analysis of inflammatory markers and DNA damage. The subjects will be randomized into two groups, FESG (functional electrical stimulation group) and CG (control group). The first will receive the FES in the quadriceps muscle of both thighs, for eight weeks, three times a week during hemodialysis session. While the control group only will be evaluated and re-evaluated. Expected results at the end of the protocol with FES are: increased quadriceps muscle thickness; longest distance covered on the six-minute walk test; improved quality of life; increase in resistance of the lower limbs; increased muscle strength of the lower limbs; improved endothelial function; improved inflammatory status and DNA damage.

A 4 week-duration cross-over study on Ticagrelor and Clopidogrel for the Acute Coronary Syndrome (ACS) and Chronic Kidney Disease (CKD) subjects, focusing on the platelet inhibition and safety observation.

Anticalins® are engineered human proteins that are able to bind specific target molecules. The Anticalin PRS-080#022-DP to be investigated in this study is directed against hepcidin and is intended for the treatment of anemia of chronic disease. This Phase Ib study shall investigate the safety, pharmacokinetics and pharmacodynamics of a single administration of PRS-080#022-DP in anemic stage 5 chronic kidney disease patients undergoing hemodialysis.

In recent years, several studies revealed that the current influenza vaccine strategy might be of minimal vaccine effectiveness and had a smaller effect on reducing morbidity and mortality in the end-stage renal disease population than previously thought. Thus, this also raised the question about the effectiveness of administration of influenza vaccination in chronic kidney disease patients not on dialysis. In this study, the investigators aim to evaluate the effectiveness of seasonal trivalent influenza vaccine, formulation 2013-2014, in patients with different stage of chronic kidney disease (CKD) not on dialysis.

The safety and efficacy of Caltriol on mild proteinuria (<1.0g/d) reduction in CKD patients.

Patients with Chronic Kidney Disease (CKD) are upto 3.5 times more likely to die from diseases of heart and blood vessels (Cardiovascular Disease-CVD). Vitamin D insufficiency is very common in CKD and associated with CVD. Animal studies have shown an improvement in heart size and function with Vitamin D therapy, although evidence in humans is lacking. The proposed study will test if oral Vitamin D treatment, in deficient CKD patients, will improve heart enlargement and function. With these proposed changes the investigators expect to reduce CVD and deaths in patients with CKD.

Active vitamin D at therapeutic dose may prevent vascular calcification but in supraphysiologic dose may precipitate it.

The purpose of this study is to evaluate the effects of high intensity interval training compared to moderate exercise training and a control group on exercise capacity and quality of life in patients with end stage renal disease on hemodialysis.

Indoxyl sulfate (IS) is a uremic toxin that accelerates the progression of chronic kidney disease (CKD). AST-120 (Kremezin®; Kureha Corporation, Tokyo, Japan) removes indole, which is the precursor of IS, in the intestine, and reduces the accumulation of IS. This drug has been shown to retard the deterioration of renal function in CKD patients through reducing the levels of IS. IS was reported to promote aortic calcification and stimulate the proliferation of vascular smooth muscle cells (VSMC). IS also inhibits endothelial proliferation and wound repair. With this background, the investigators will performed the study whether AST-120 improve the endothelial dysfunction in CKD patients.
