Global Study of MK-2060 (Anti-Factor XI Monoclonal Antibody) in Participants With End Stage Renal...
End-Stage Renal DiseaseEnd-Stage Kidney Disease2 moreThe purpose of this study is to evaluate the efficacy and safety of two different doses of MK-2060 (a monoclonal antibody against Factor XI) in end stage renal disease (ESRD) participants receiving hemodialysis via an arteriovenous graft (AVG). Data from this study will be used to aid dose selection of MK-2060 in future studies. The primary hypothesis is that at least one of the MK-2060 doses is superior to placebo in increasing the time to first occurrence of AVG event.
Arterial Stiffness in Heart Failure and Chronic Kidney Disease
Arterial StiffnessThis observational study is assessing the effects that arterial stiffness may have on patients with heart failure (HF) and chronic kidney disease (CKD). Arterial stiffness will be measured by assessing pulse wave velocity (PWV). Carotid- Femoral PWV is the gold standard in measuring arterial stiffness non- invasively. Many studies have shown increasing PWV is a predictor of cardiovascular events, but the significance of increasing PWV as a surrogate marker for the potential worsening (decompensation) of HF or CKD has not been explored. This study aims to investigate patients with HF and CKD by assessing PWV while in a decompensated state and again when in a stable condition after 4 weeks of discharge to investigate a link between decompensation and rise of arterial stiffness. The research team aim to recruit 120 patients in this study with 40 patients in each of the 3 groups- heart failure with reduced ejection fraction (HFrEF), heart failure with preserved ejection fraction (HFpEF) and acute kidney injury (AKI). All AKI patients would have had known CKD (stages 3a, 3b or 4). The study participants will be initially recruited in hospital while admitted in an acute state and tests including bloods, ECG, echocardiography and PWV will be performed. The tests (excluding echocardiography) will be repeated 4 weeks after discharge. There is no intervention in this study. The study seeks to improve the understanding of the role of the vasculature in the development of acute HF in the two common types- HFrEF and HFpEF. As CKD is a common comorbidity in heart failure patients we felt that a study of the behaviour of arterial stiffness in this cohort will add to this understanding. If arterial stiffness is found to be an important component of the HF syndrome therapeutic interest could be focused at managing arterial stiffness with novel therapy.
Dietary Potassium Liberalization in Pre-Dialysis Patients
Chronic Kidney DiseaseHyperkalemiaThe study will look at the impact of the potassium content in fruits and vegetables, on serum potassium concentrations in people with Chronic Kidney Disease (CKD) using a randomized crossover design. Participants will receive home delivery of fruit and vegetables with either higher or lower potassium content in a random order. Clinical chemistry markers from blood and urine samples, blood pressure, physical functioning and health related quality of life will be assessed throughout the duration of the trial. This study will also measure their physical functioning, using a chair stand test. The results of this study could change the dietary recommendations for people with CKD related to potassium.

Repository of Novel Analytes Leading to Autoimmune, Inflammatory and Diabetic Nephropathies (RENAL...
Kidney DiseasesKidney Failure5 moreA central goal of this data repository is to collect data from a large population of subjects with a variety of renal disease states. Cohorts will include subjects with diabetes, inflammatory/autoimmune and transplant related renal conditions. Additionally, the repository will have the capacity to store biospecimens and electronic data in control subjects without established renal disease. This initiative will provide an opportunity to compare data from various disease states and controls with the objective of determining clinical and biological factors that predict disease progression, response to therapy and identify discriminating noninvasive clinical and biological features that predict renal biopsy findings.
Immune System Related Kidney Disease
Kidney DiseaseNephrotic SyndromeKidney diseases related to the immune system include, nephrotic syndrome, glomerulonephritis, membranous nephropathy, lupus nephritis, and nephritis associated with connective tissue disorders. This study will allow researchers to admit and follow patients suffering from autoimmune diseases of the kidney. It will attempt to provide information about the causes and specific abnormalities associated with autoimmune kidney disease. Patients with kidney disease as a result of their immune system, and patients with diseases of the immune system who may later develop kidney disease, will be potential subjects for this study. Patients will undergo a history and physical examination, and standard laboratory test to more closely understand the causes, signs, symptoms, and responses to medication of these diseases. Based on these evaluations the patients may qualify as candidates for other experimental studies. At any time these patients may be asked to submit blood or urine samples for further research.
The Role of Isolated Nocturnal Hypertension Pattern in Nondialysis CKD
Chronic Kidney DiseaseIsolated nocturnal hypertension (INH) has been studied among the general population and hypertensive patients. However, little insight is available on the prognostic effect of INH in patients with chronic kidney disease (CKD). This study investigated the prognostic effect of INH in a cohort of Chinese patients with nondialysis CKD.
Nanshan Elderly Cohort Study
HypertensionType 2 Diabetes Mellitus8 moreObjective: The Nanshan Elderly Cohort Study (NECS) aims to investigate the nutritional, as well as other environmental and genetic factors of chronic diseases, such as cardio-metabolic diseases. Study design: NECS is a community-based prospective cohort study. Participants: About 10000-20000 apparently healthy residents, living in Nanshan, Shenzhen (South China) for >5 years, aged ≥ 65 years, will be recruited between 2018 and 2019. Visits and Data Collection: Participants will be followed up approximately every 3 years by invited to the Community Healthcare Service Centre.
