Trial to Evaluate Reduction in Inflammation in Patients With Advanced Chronic Renal Disease Utilizing Antibody Mediated IL-6 Inhibition in Japan.

The purpose of this research study is to compare the safety and effectiveness of 2 different doses of a study drug called ziltivekimab to placebo (an inactive substance) in reducing inflammation and improving some of the bad effects of inflammation on heart disease. Participants will be randomly (by chance) assigned to receive either ziltivekimab or placebo. The chance that participants will be assigned into one of the three study arms of ziltivekimab (either 15 mg or 30 mg) or placebo is the same (approximately 33%). This is a double-blind study, which means neither participants nor the study doctor will know which group the participants are in. In case of an emergency, however, the study doctor can get this information. The study drug will be injected under the skin once every 4 weeks. In this study participants will receive 3 injections of study drug. The total study duration for each participant will be approximately 6 months.

Mechanisms of EPO-induced Hypertension

The investigators hypothesize that compared to untreated controls, erythropoietin (EPO) therapy in anemic patients with chronic kidney disease will raise diastolic blood pressure (BP). The magnitude of increase in diastolic BP at 12 weeks after treatment will be related to two factors. First, endothelial dysfunction and worsening of endothelial function from baseline to 4 weeks and second, the change of forearm blood flow in response to breathing oxygen and the change in this measure from baseline to 4 weeks. Study procedures include fasting blood draws, ambulatory blood pressure, urine collection, and forearm blood flow tests. The study hopes to accrue 160 subjects.

L-arginine to Reduce Sympathetic Nerve Activity in CKD Patients

Chronic kidney disease (CKD) is associated with a higher risk of cardiovascular disease and death. An overactive sympathetic nervous system in CKD patients is one of the major mechanisms increasing the cardiovascular risks in this patient population. A potential signal driving sympathetic nerve activity (SNA) involves accumulation of the endogenous nitric oxide synthase (NOS) inhibitor asymmetric dimethylarginine (ADMA). ADMA is elevated in CKD and is a strong, independent predictor of future cardiovascular events in these patients. . The goal of this study is to determine whether overcoming the accumulation of endogenous ADMA with acute L-arginine infusion reduces SNA in CKD patients.

Trial of Nicotinamide Riboside and Co-enzyme Q10 in Chronic Kidney Disease

Chronic kidney disease is associated with the loss of skeletal muscle mass and function. This process detrimentally impacts mobility, functional independence, and quality of life. Mounting evidence suggests that chronic kidney disease impairs skeletal muscle functioning by injuring mitochondria, the central energy producing units of cells. Potential treatment options to restore mitochondrial function include aerobic and weight bearing exercise and medications that directly improve mitochondrial energetics. Unfortunately, exercise programs may be difficult to implement in people who have chronic diseases, such as kidney disease.. Coenzyme Q10 (coQ10) and nicotinamide riboside (NR) are naturally occurring supplements that can directly improve mitochondrial efficiency. Both compounds help mitochondria produce more energy while generating less waste. The primary purpose of this study is to test whether coQ10 and NR can improve muscle function among people with chronic kidney disease. What we learn in this study may help us better understand the mechanisms of skeletal muscle impairment among people with kidney disease and ultimately improve their ability to be active and independent.

Evaluation of Fructose Ingestion and the Renin Angiotensin System in Humans

Fructose is an ingredient that is added to many of our foods. It is a cheaper, sweeter additive that can be found in everything from soda pop to yogurt to granola bars. In the last few years a significant number of studies have been published linking consumption of fructose with obesity, hypertension and more recently, kidney and cardiovascular disease. Animal studies show a strong link between excessive ingestion of fructose and the development of kidney and cardiovascular disease mediated by the renin angiotensin system, a hormonal system whose activation is detrimental to both the kidney and the heart. There has been very little research done on the potentially pathophysiological relationship between a high fructose diet and kidney and cardiovascular disease in humans. The investigators hypothesize that ingestion of fructose will result in upregulation of the renin angiotensin system in humans. Cardiovascular disease in women is a significant risk factor. By having women participate who are on the birth control pill and as well as women who use non oral forms of birth control or no birth control, kidney function and cardiovascular health can be examined as it relates to in the influence oral hormones might play. How the kidney responds to the influence of sugar and fructose while a woman is on an oral birth control pill, may reveal mechanisms that could help us understand cardiovascular disease in women.

Trial of Pirfenidone to Prevent Progression in Chronic Kidney Disease

Kidney disease is a global health problem, affecting more than 10% of the world's population and more than half of adults over 70 years of age in the United States. Persons with kidney disease are at higher risk for cardiovascular disease, heart failure, physical function decline, and mortality. Kidney scarring is a dominant factor in the development of kidney disease. Our group has evaluated several tests to determine the severity of scarring without requiring kidney biopsies, using MRI imaging scans and evaluating markers of scarring that we can measure in the urine. In this study we will use these measures to evaluate pirfenidone as a promising potential new treatment for patients with kidney disease.

Mechanisms of Diabetic Nephropathy in Ecuador

The prevalence of diabetes mellitus (DM) is increasing worldwide, suggesting that 45% of diabetics are undiagnosed. DM induces a kidney disease called diabetic nephropathy (DN) which is the largest single cause of end-stage renal disease and dialysis requirement. In South America the prevalence of DM and chronic kidney disease has increased, and great disparity exists among countries in regards to access to the dialysis treatment. It has been considerate that Hispanic origin increases the risk for DM. The South Americans have distinctive habits, culture, environment, behavior and genetic background and the factors involved in DN have not been defined yet. The early kidney lesions such as neoangiogenesis (pathologic generation of the new blood vessels) and extracellular matrix expansion have been described. The vascular endothelial growth factor A (VEGF) has been linked to angiogenesis, but the role of VEGF in DN has not been elucidated yet. VEGF signals mainly through VEGF receptor 2 (VEGFR2). VEGFR2 interacts with alphaV beta3 integrin (AVB3) in kidney. Additionally tenascin C is expressed in the extracellular matrix. Tenascin C and the tenascin C/AVB3 complex have also been linked to angiogenesis, however their roles have not been unveiled yet in the DN. Investigators hypothesize that VEGF signaling and tenascin C play an important role in DN and that VEGFR2, AVB3 and tenascin C interact. The purposes of this study is to characterize social, environmental and biological factors implicated in the DN in Ecuador and define the role of VEGF signaling and tenascin C in the pathogenesis of the DN. Investigators propose to study factors involved in DN in diabetic and non-diabetic adults from general population, with and without DN. In a single time investigators will evaluate demographics data, habits, personal and family history through a survey. Investigators will measure anthropometrics parameters and blood pressure; investigators will quantify blood glucose, glycosylated hemoglobin A1c and proteinuria. In addition investigators will examine the role of tenascin C and VEGF signaling by analyzing paraffin embedded kidney tissue, plasma and urine samples. Characterizing the factors involved in the DN from Hispanic people is key to establish adequate strategies of prevention, diagnosis and treatment in this population. Furthermore elucidating the role of proteins involved in DN may offer valuable tools for the development of new treatments.

Bicarbonate Administration in CKD

Low serum bicarbonate levels, even within the normal laboratory range, are strongly associated with increased risks of hypertension, endothelial dysfunction, cardiovascular disease and death. The current proposal will investigate whether bicarbonate administration in patients with chronic kidney disease (CKD) will improve the health and function of arteries and reduce the size of the left ventricle of the heart. Overall, the proposed research will provide important new scientific evidence upon which physicians can base recommendations to patients with CKD to decrease the risk of developing cardiovascular diseases.
