Filter by:This study is to assess the effect of 48 weeks administration of Renamezin capsule on prevention of sarcopenia in pre-dialysis patients with chronic kidney disease.
Renal impairment is common in patients with chronic hepatitis B infection. For those taking nucleotide analogues, renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. In this prospective study, consecutive CHB patients on combined lamivudine (LAM)+ADV/TDF are switched to LdT+ADV/TDF at recruitment and are followed up for 24 months. Estimated glomerular filtration rate (eGFR) is calculated with the Modification of Diet in Renal Disease (MDRD) equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers are investigated in cultured renal tubular epithelial cell line HK-2.
Patients with diabetes mellitus (DM) and chronic kidney disease (CKD) are at increased risk of atherothrombotic events. Clopidogrel is the most widely used platelet P2Y12 receptor inhibitor in patients with coronary artery disease (CAD). However, despite its benefits, many patients still experience recurrent atherothrombotic events. The proposed study will test the central hypothesis that in DM patients the presence of CKD reduces clopidogrel-mediated P2Y12 inhibitory effects through synergistic mechanisms, which include upregulation of the P2Y12 signaling pathway and impaired clopidogrel metabolism.
Premature cardiovascular disease (CVD) is the leading cause of death in patients with kidney disease (CKD). Excessive cardiac mortality is thought to be secondary to non-atherosclerotic processes, with left ventricular (LV) hypertrophy (LVH) and remodelling being the predominant phenotypical features. Along with other risk factors, subclinical ischaemia and haemodynamic perturbations associated with haemodialysis (HD) are thought to contribute to the ultimate development of LV systolic and diastolic dysfunction. The development of these adverse features reflects a specific cardiomyopathy due to CKD and subsequently, to uraemia. Patients receiving hemodialysis (HD) have a higher incidence rate of heart failure (predominantly with preserved ejection fraction), with phenotypically eccentric hypertrophic remodelling, systolic and diastolic dysfunction as well as high rate of interstitial myocardial fibrosis. Detection and ultimately reversal of the development of this CKD-related cardiomyopathy are important goals for improving the CVD, morbidity and mortality of CKD patients.The objectives of this study are, firstly, to investigate the complex myocardial phenotype in patients with various stages of CKD, secondly, to relate the CMR-measures to outcome, and thirdly, to be able to estimate the effects of chronic uremia/hypervolemia. Deciphering the predominant driver of remodelling on an individual level may help to personalise anti-remodelling strategies. Native T1 and T2 mapping imaging provide non-invasive imaging tools to detect myocardial fibrosis and oedema, respectively. Prognostic associations of these measures may clarify the relative prevalence of adverse phenotype and their relative contribution to adverse events and poor outcome. The role of chronic water retention and uraemia may be associated with interstitial myocardial oedema promoting further the remodelling process.
This two-year pilot study will test whether a one-page "Jumpstart Form" will affect goals-of-care discussions in the hospital. This form will be provided to clinicians and will include patient-specific information about preferences for goals-of-care communication and for care, as well as tips to improve this communication. Jumpstart forms will also be provided to patients or, if they are unable to communicate, their surrogates/family members. The information on the form will be obtained from questionnaires. The form is tailored to help patients and surrogates talk with clinicians about goals of care. This study is based on a successful application of Jumpstart Form in the outpatient clinic setting.
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.
Our study investigated the effect of using a known drug used in intermittent claudication (named pentoxifylline) as an adjuvant to erythropoietin stimulating agents to improve anemia of hemodialysis patients.
This is a prospective, single arm, multi-center, observational clinical study of the DyeVert Plus System. The DyeVert Plus System is an FDA-cleared device designed to reduce contrast media volume delivered during angiography and permit real-time contrast media volume monitoring.
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.
