Filter by:Chronic kidney disease (CKD) and its end stage of kidney failure are major public health problems in Canada and worldwide. In the primary care setting, accurate prediction of the risk of kidney failure in patients with CKD can improve patient provider communication, assist in appropriate nephrology referral, improve dialysis treatment planning, and identify patients who are most likely to benefit from intervention. To aid in accurately predicting the risk of kidney failure requiring dialysis in patients with CKD, the primary investigator has developed and validated the kidney failure risk equation (KFRE), which is increasingly used in nephrology practices across Canada and the United States. In this current study, a cluster randomized controlled trial (RCT) will be done in collaboration with the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). Primary care clinics that can integrate the KFRE into their electronic medical records will be randomized to receive the intervention (patients and providers receive individualized information explaining kidney failure risk, as well as risk-based criteria for referral, alongside usual care) versus usual care alone (no information on personalized risk and no risk-based referral). In both groups, the investigators will assess management of patients at high risk of kidney failure (patient), timing of referral for patients at high risk of kidney failure (health system), cost of CKD care (health system), CKD-specific health literacy (patient), trust in physician care (patient), and satisfaction with risk prediction tools (provider). The objective of this research study is to develop, implement, and evaluate tools to guide the care of patients with CKD in the community, including appropriate referral using a risk-based approach. Specifically, this study will address the question: "Does providing patients (and their physicians) with information about their risk of kidney failure improve quality of care, health literacy, and trust in the care they are receiving?"
Chronic kidney disease patients with sarcopenic obesity are noted to have impairment in physical performance and reducing their quality of life, and the investigators also founded these patients are at higher risk of mortality. Thus, the investigators hypothesize that oral nutrition intervention could increase lean tissue mass in these patients and improve the clinical outcomes.
Acute kidney injury (AKI) involves poor prognosis in ICU patients. The renal prognosis at long term is unknown. The study will determine chronic kidney injury incidence and quality of life, five years after AK during ICU stay.
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.
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.
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.
CKD is a global endemic disease with increased comorbidities and mortality. The prevalence and the incidence of the end-stage renal disease (ESRD) are extremely high in Taiwan. The prevalence of CKD remains high; however, the awareness remains low. Screening of unique risk factor and early diagnosis of CKD can improve outcome. Furthermore, data of renal education deep into the community remains limited. The aims of this study are: 1. Explore risk factors associated with CKD in the community 2. Establish multidisciplinary care model in the community 3. Investigate mechanistic mediators for CKD and multidisciplinary education approached in behavioral , physiological, immune and metabolomics aspects 4. Provide bio-specimen repository for future study
Chronic kidney disease (CKD) is an increasing public health problem and the number of patient with chronic kidney disease is increasing worldwide. Bone abnormalities are found almost universally in patients with CKD requiring dialysis and in the majority of patients with CKD stages 3-5. Chronic kidney disease-mineral bone disorder (CKD-MBD) is a complex disorder of bone and mineral metabolism, which is associated with disorder in circulating levels of hormones and development of secondary hyperparathyroid disease. The abnormalities of mineral homeostasis impair bone remodeling and mineralization and results in cortical and trabecular defects and an increased fracture risk. There is also an association with increased morbidity and mortality. CKD-MBD is also associated with development of calcification of the blood vessels. During the last decade it has been increasingly acknowledged that mineral and bone disorder contribute to the excessively high cardiovascular morbidity and mortality in patients with chronic kidney disease. The diagnosis of mineral bone disorder and the underlying bone histology in CKD patients is challenging. The treatment of renal osteodystrophy (ROD) and especially the treatment of fractures in this patient group, depends on the underlying bone histopathology and bone turnover. The gold standard for diagnosing the subtypes of ROD is bone biopsy, but it is invasive and requires considerable expertise regarding quantitative histomorphometry and interpretation. Plasma parathormone (PTH) measurement is commonly used to evaluate these patients, and generally extremely high or low PTH levels predict the underlying bone disorder. Still PTHs ability to correctly estimate turnover in bone is limited. Several biomarkers such as tartrate-resistant acid phosphatase 5b (TRAP5b) and procollagen type 1 N-terminal propetide (PINP) has been investigated, but no biomarker in clinical use has yet been proven suitable or superior to PTH to estimate overall bone histology. 18F-NaF positron emission tomography (18F-NaF PET) is a noninvasive quantitative imaging technique that allows assessment of regional bone turnover at clinically relevant sites. 18F-NaF is a bone-seeking tracer, which reflects remodeling of bone and osteoblast activity25. 18F-NaF serves as an efficient tracer to measure metabolic changes in bone. A correlation between histomorphometric markers such as bone formation rate (BFR) and tracer activity in the 18F- NaF PET scan in CKD patients has previously been shown in one small study. This study`s goal is to evaluate, if 18-NaF-Positron emission tomography-computed tomography (18F-PET-TT) can be used in the assessment of CKD patients. The hypothesis is that 18F-PET-TT correlates with the histomorphometry of bone biopsy and with the calcification score in CKD patients and that 18F-PET-TT maybe can be used as a diagnostic imaging technique in the future.
