Filter by:This study aims to understand the onset an functional consequences of left ventricular interstitial fibrosis in patients with chronic kidney disease (stage 2 to 5), as well as assess whether transplantation results in a regression of cardiac fibrosis.Thus all patients will undergo: 1) a cardiac magnetic resonance imaging (MRI) scan to assess cardiac function and measure left ventricular interstitial fibrosis; 2) a cardiopulmonary stress echocardiogram to understand the functional consequences of fibrosis and rule out any underlying ischaemic heart disease; 3) a 24 hour holter monitor and electrocardiogram (ECG) to assess whether these patients are at higher risk of arrhythmia.
Currently there is no standard way to detect age-related skeletal muscle loss in patients with chronic kidney disease. Investigators are working on finding rapid and inexpensive ways to measure muscle size and fat within the muscle.
To compare clinical outcomes in patients with chronic kidney disease (CKD) presenting with an acute coronary syndrome (ACS) treated with clopidogrel or ticagrelor (both FDA approved and guideline indicated drugs for treating these patients upstream managed medically or with coronary revascularization).
The national drug safety agency authorizes nominatively the use of sodium thiosulfate in dialysis patients with calciphylaxis. To date, it is the largest global cohort (more 600 patients from 2012 to 2016). We wanted to study retrospectively the fate of these patients at 6 months including mortality. Early use improves effectiveness.
Chronic kidney disease (CKD) and (subsequent) acute kidney injury are frequent in patients undergoing transcatheter aortic valve implantation (TAVI). Moreover, these patients are easily hypervolemic and susceptible for cardiac decompensation. Prevention of contrast induced nephropathy (CIN) has not yet been studied in these patients, and evidence on different strategies is urgently needed. The objective of this study is to evaluate the efficacy of 250ml 1.4% sodium bicarbonate versus hypotone saline (0.65% sodiumchloride) hydration prior to TAVI in patients with CKD to prevent CIN.
Due to their immunosuppressive therapy, solid-organ transplant (SOT) recipients bear a 10 to 100 times higher risk of human papillomavirus (HPV)-associated malignancies than healthy individuals. The objectives of this observational, non-interventional multi-national, multi-centre research project are to gain an insight into current HPV vaccination strategies and to investigate the immune response to different routinely administered HPV vaccines in European paediatric SOT candidates and immunocompromised transplant recipients, enabling patients at risk of vaccination failure to be identified.
Based on clinical evidence based medicine and organizational management model, investigators redesign the prevention and treatment of chronic kidney disease of public health system in Shanghai China. The investigators hope to find early chronic kidney disease, prevention and clinical intervention of orderly combination. The advantages of this system were confirmed by comparing the prevalence rate, awareness rate and treatment rate before and after the completion of the system.
Chronic kidney disease (CKD) patients often have associated systemic hypertension due to volume retention, as one of the mechanisms, therefore the use of diuretics is widespread in this population. One of the major complications of CKD is mineral and bone metabolism disorder (CKD-MBD), which include changes in the levels of calcium, phosphorus, vitamin D deficiency, increased circulating levels of fibroblast growth factor (FGF-23) and parathyroid hormone (PTH). These alterations are responsible for fractures, cardiovascular disease and mortality among patients with CKD. According to diuretic mechanism of action, sometimes increasing serum calcium (in the case of furosemide), sometimes decreasing it (in the case of thiazide), it is expected that the serum calcium may be altered, even within the range of normality, with consequent impact on the levels of PTH. Although most studies have shown that the use of thiazide diuretics decreases the risk of fractures, some showed the opposite. Similarly, although most studies have shown increased risk of fracture in association to loop diuretics use, some have failed in demonstrated this outcome. Only one study, a cohort study in a population of CKD, showed that furosemide was directly related to increased calciuria and PTH levels and the use of thiazide, in turn, showed completely opposite effect. However, certain issues are still not completely solved, for example, the interference of renal function itself on calciuria. It is possible that calciuria is not a so simple explanation that justifies the PTH levels changes, as no correlation was seen between calciuria and PTH levels. Better understanding of the exact relationship between the use of diuretics and the impact on CKD-MBD may be an alternative intervention, easily accessible and relatively inexpensive. The purpose of this study is to evaluate the impact of diuretic, specifically hydrochlorothiazide and furosemide, on bone architecture and mineral metabolism.
This will be a prospective, single institution, parallel-group, single-blinded, randomized-controlled, two-arm, effectiveness study comparing autologous arteriovenous fistula versus hemodialysis access grafts in the elderly. The target sample size will include enrollment of 270 patients over a period of 5 years. The creation of an autologous arteriovenous fistula or placement of a hemodialysis access graft constitutes the two arms of the study.
Our study seeks to define the effect of each component of the distal revascularization interval ligation (DRIL) procedure on the in vivo distal blood pressure of patients with ischemic steal, and to determine whether the interval ligation component of the DRIL procedure is necessary or not.
