Active clinical trials for "Kidney Diseases"

Infants born preterm and of low birth weight are known to be at increased risk for early onset of cardiovascular and renal disease in adult life. This has been related to low nephron mass due to inadequate or early termination of glomerulogenesis in utero and during the perinatal period. Risks for subsequent development of hypertension and kidney disease include proteinuria, excessive weight gain during early life with insulin resistance and supplemental high calorie feedings. The long-term goal is for early diagnosis of those infants who are at risk for future development of hypertension and kidney disease so that the investigators might intervene to potentially avert progression to adult disease. The objective of this clinical trial is to acquire data on the natural history of neonatal kidney function and size in infants born preterm during the first 2 years of life. This will be done through the use of standard serum and urine markers as well as non-invasive ultrasound technology. The central hypothesis of this clinical trial is that a subgroup of patients born preterm and of low birth weight will demonstrate early markers of kidney injury including elevated serum cystatin C, proteinuria and low kidney size. This hypothesis has been formulated on the basis of preliminary data from our group studying this question retrospectively in older children born prematurely who have developed overt kidney disease. The rationale for the proposed research is to develop early serum and demographic markers of pre-clinical kidney disease so that early intervention can occur. The proposed clinical trial is innovative because it will investigate the risk factors for kidney dysfunction at a pre-clinical stage with the idea of gaining more knowledge regarding therapeutic interventions. In addition, the study will assess serum cystatin C as a surrogate test for glomerular filtration rate which could indicate worsening kidney function at an earlier stage than serum creatinine. The proposed research is significant because it is expected to identify at-risk patients for future renal impairment and to prospectively monitor the persistence of proteinuria and its effect on kidney function in the short term.

Nicorandil is potentially effective to prevent cardiovascular events in patients with coronary artery disease (CAD) receiving hemodialysis. The purpose of this study is to prospectively investigate whether nicorandil is effective in reducing the incidence of cardiovascular events in patients with CAD on hemodialysis.

This is a Phase I, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity of a 10 mg/kg dose of AD-214 when administered to healthy volunteers (HVs) (Part A) or patients with interstitial lung disease (ILD) or chronic kidney disease (CKD) (Part B). The study will be performed in Australia at up to two clinical sites.

Evaluate the effectiveness of different modalities of physical exercise about clinical health indicators and quality of life of patients with chronic kidney disease undergoing hemodialysis.

With the improvement of people's living standard, the prevalence of Diabetes is increasing year by year. In present, 350 million people worldwide are suffering from diabetes, and by 2035, there will be as high as 600 million. Diabetes causes a variety of complications, including diabetic nephropathy, which is one of the most common complications of Diabetes. Diabetic nephropathy is a microvascular complication of diabetes. Microalbuminuria and glomerular filtration rate decrease are the main manifestation. Even more, it can progress to end-stage renal changes. Data showed that diabetic nephropathy accounts for about 40% of patients with end-stage renal disease receiving renal replacement therapy. However, the treatment of diabetic nephropathy is still lacking. In the past 40 years, few drugs have been proven to ameliorate the progression of diabetic nephropathy. Even though, the renal function of a large number of diabetic nephropathy patients is gradually deteriorating. Therefore, it is urgent to find a therapeutic drug that acts on different targets. Trimetazidine is a piperazine derivative. It is mainly used in the treatment of stable angina pectoris. Its safety has been well verified. In recent years, the role of trimetazidine in acute renal damage has been widely reported. A large number of studies have shown that trimetazidine can reduce the effect of contrast agent on renal function and reduce the incidence of contrast nephropathy. There fore, Trimetazidine is a promising drug for delaying the progression of diabetic nephropathy.

This is a prospective, observational study to assess the effect of SGLT2 inhibitors on surrogate markers of kidney and cardiovascular health in patients with stage 3b and 4 chronic kidney disease (CKD). This study includes three clinic in person visits and weekly telephone visits for 12 weeks. Recruit 28 patients with CKD stages 3b-4 and follow up for 12 weeks Determine the effect of interventions on the primary outcome variable serum klotho measured by immunoprecipitation-immunoblot

The SLEEP-BP-CKD Study has been designed to specifically test the following primary hypotheses: (i) Specific ABPM-derived parameters, in particular the asleep SBP mean and/or the sleep-time relative SBP decline, are significant prognostic markers of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. (ii) Changes during follow-up in specific ABPM-derived parameters, in particular the increase of the asleep SBP mean and/or decrease of the sleep-time relative SBP decline towards the non-dipper/riser 24h SBP pattern, are significant prognostic markers of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. A novelty of the SLEEP-BP-CKD Study is the incorporation of clinical-grade wearable digital technology to monitor both wake-time and sleep-time BP at home in a subgroup (up to 200) of the total sample; this procedure will provide added useful information to test the following additional hypotheses: (iii) The HBPM self-assessment procedure to obtain BP measurements both during wake-time and sleep-time spans provides reliable data to be used either individually or jointly with periodic ABPM as added potential prognostic marker of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. (iv) The sleep-time BP measurements obtained by HBPM self-assessment and their changes during follow-up are better correlated, compared with wake-time OBPM or wake-time HBPM, to eGFR and albuminuria (measured by the albumin/creatinine ratio) and their changes during follow-up, respectively. (v) The HBPM self-assessment procedure to obtain BP measurements both during wake-time and sleep-time spans increases patient adherence/compliance to prescribed treatment from baseline. The scheduled periodic patient BP assessments during follow-up with OBPM, HBPM, 48h ABPM, along with laboratory urine and blood test data will further allow evaluating and comparing the changes from baseline in all these clinically relevant variables as potential markers for risk of progression towards ESKD, all-cause mortality, and/or CVD morbidity.

Chronic kidney disease (CKD) refers to a variety of different diseases characterized by impairment of kidney structure and/or renal function. The prevalence of CKD in China is as high as 10.8%. With a population of more than 150 million, China has the largest number of CKD patients all over the world. People with CKD would not only progress to uremia and need renal replace treatment, it also significantly increases risk of cardiovascular disease than non-CKD population. It has created a heavy burden on people's health and national economy. There is an urgent need to establish an effective system for CKD prevention and control in China. Evidences from large sample cohort and real world based research are still rare. This study will provide good experience for reducing the occurrence and development of CKD.

Studying the causal roles of components of the renin-angiotensin-aldosterone system (including angiotensin-(1-7) (Ang-(1-7)), angiotensin-converting enzyme 2 (ACE2), Ang II, and ACE), uric acid, and klotho in pediatric hypertension and related target organ injury, including in the heart, kidneys, vasculature, and brain. Recruiting children with a new hypertension diagnosis over a 2-year period from the Hypertension and Pediatric Nephrology Clinics affiliated with Brenner Children's Hospital at Atrium Health Wake Forest Baptist and Atrium Health Levine Children's Hospital. Healthy control participants will be recruited from local general primary care practices. Collecting blood and urine samples to analyze components of the renin-angiotensin-aldosterone system (Ang-(1-7), ACE2, Ang II, ACE), uric acid, and klotho, and measuring blood pressure, heart structure and function, autonomic function, vascular function, and kidney function at baseline, year 1, and year 2. Objectives are to investigate phenotypic and treatment response variability and to causally infer if Ang-(1-7), ACE2, Ang II, ACE, uric acid, and klotho contribute to target organ injury due to hypertension.
