Filter by:This study proposes to investigate the acceptability and efficacy of intermittent VLED (5:2 diet) plus exercise, compared with the investigator's established Weight Management Programme (WMP), in obese patients with CKD, using feasibility study methodology. Patients will be invited to participate in the parallel arm, single blinded, randomised controlled feasibility study, and randomly allocated to 1 of 2 treatments for 6 months. The experimental arm involves an intermittent modified fasting regimen consisting of VLED (600 kcal/day) on 2 consecutive days, and 5 days each week on a modified diet to maintain an overall energy deficit of 600 kcal/day across the week (5:2 diet). The control arm will be the standard renal WMP with a continuous energy restricted diet aimed at reducing daily energy intake by 600 kcal/day. The feasibility outcomes are: recruitment rate >50%; intervention retention rate at 6 months >60%; dietary intervention compliance; and weight loss. Secondary outcomes include safety, body composition, proteinuria, lipids, blood pressure, and eating desire. Measurements will be made at baseline, midpoint, and twice at endpoint.
This study aims to determine changes in kidney function during and after critical illness, comparing conventional creatinine based methods with the gold standard to accurately establish the presence of new or worsened chronic kidney disease. In addition, investigators will assess the confounding effect of muscle wasting on the conventional assessment of kidney function and investigate the information that measures of kidney function may contribute to the assessment of musculoskeletal health after critical illness.
The aim of this cohort study is: To investigate the etiology and epidemiology of comorbidities in CKD; To find out risk factors associated with the mortality of CKD; To find out uremic toxins which are related to the mortality and comorbidities of CKD; To focuse on the association between uremic toxins and inflammation, oxidative stress and nutritional status in CKD.
Cardiovascular disease (CVD) remains the leading cause of death in patients with Chronic Kidney Disease (CKD). Patients who spend a lot of time being inactive have an increased chance of developing CVD. Thus, interventions that can help to increase the levels of physical activity in patients with CKD are needed. A recent study the investigators completed with kidney transplant participants showed a benefit from the investigators supervised exercise programme. However, the investigators results showed that 11 of the 18 patients who dropped out from the 12-month study were from black and minority ethnic groups. Some patient feedback from these participants suggested that cultural beliefs; including women not being comfortable to exercise in front of men in an exercise class environment, and difficulties around appropriate dress for exercise classes, contributed to some of these participants' decisions to withdraw from the study. This has prompted the investigators to investigate, the cultural influences that may contribute to patient decisions about partaking in physical activity and exercise training. The aim of this study is therefore to invite patients with CKD from the three most widely represented ethnic groups found in our South-East London Hospital Trust (Black African and African-Caribbean; South Asian, and White Caucasian patients) to discuss their beliefs and the cultural influences that may affect their decision on whether to engage with exercise and physical activity. Participants will complete a questionnaire on physical activity levels, and a questionnaire that looks at a patient's readiness to be involved in physical activity, prior to attending interviews or group discussions. The questionnaires will be translated for use with non-English speaking participants and will be used to ensure we get views on physical activity from those participants who are active and not, and ready to be involved in physical activity, and not. A combination of individual interviews and group discussions will then be used to explore the understanding of the terms 'physical activity' and 'exercise', and cultural barriers to participation. The investigators will have interpreters present for all discussions, undertaken in the community. The work from this pilot study will be used to inform and design a larger multi-centre study with an aim to design physical interventions that are culturally sensitive, and appropriate for all patients with CKD in the United Kingdom.
Prospective, single-center study to evaluate the everlinQ System when used to create an endoAVF in hemodialysis patients.
The Nephrocare mHealth project supports patients with Chronic Kidney Disease with a mobile application and telemonitoring. The application includes the follow-up of blood pressure.
Prospective, single-center study to evaluate the everlinQ endoAVF System when used to create an endoAVF in hemodialysis patients. This study aims to investigate expansion of the percutaneous venous access location to the superficial system which may provide additional procedural benefit.
Renal transplantation is the optimal method of treatment for end stage kidney disease however median lifespan of a kidney transplant is around 15 years. Existing methods of measuring transplant function and structure from blood and urine markers are imperfect; renal biopsy is often performed but is invasive. Novel methods of investigating transplant function are therefore required and emerging renal MRI sequences including ASL and diffusion weighted imaging may yield helpful biomarkers. Investigators will recruit 20 patients in the first year after transplant and measure MRI biomarkers at three time points, with correlation to existing methods of measuring transplant function.
Patients with kidney failure have a much higher risk of heart disease compared to people of the same age without kidney failure. The reason for this is not fully understood. In this project we will use Cardiac MRI (CMR), which is a very detailed scan of the heart and blood vessels, to try to better understand the cardiovascular changes that occur in kidney failure. We will perform CMR scans in 30 patients before and after dialysis (a treatment for patients with kidney failure) to see whether dialysis changes the heart muscle. The same patients will also undergo another type of heart scan, called a CT scan. This will allow us to compare the pictures from the 2 different types of scan to help us better understand any damage to the heart muscle that is present. Finally, we will test a new way to measure hardening of blood vessels on CMR. These three studies will help us to better understand the heart and blood vessel changes that happen in kidney failure. This research will also be useful for patients without kidney failure. We hope to be able to use it in the future to see which new treatments might be able to reduce the risk of heart disease in patients with kidney failure.
The purpose of this study is to examine whether there are diurnal variations in magnesium and other markers related to mineral metabolism in blood from patients with chronic kidney disease (CKD) compared to healthy controls.
