Active clinical trials for "Kidney Diseases"

Contrast induced nephropathy (CIN) is an iatrogenic renal injury following intravascular administration of radio-opaque contrast media (CM) in susceptible individuals. As the third leading cause of hospital acquired renal failure, it is associated with increased mortality, morbidity and prolonged hospital stay. Endovascular procedures have gained greater popularity in the past decade due to the advance in technology. This has also led to the increased incidence of CIN after vascular surgeries. We are conducting a retrospective cohort study in Singapore General Hospital using our perioperative database collected in the past five years. We will be extracting relevant patient perioperative information including both clinical diagnosis and lab values. Our primary aim is to establish the incidence of CIN among vascular patients with or without pre-existing chronic renal impairment undergoing elective peripheral endovascular angioplasty. Our secondary aims are to establish the risk factors and protective factors that lead to the development of CIN in vascular patients after peripheral endovascular angioplasty. We will also be looking at the long-term outcome of patients who have developed CIN after vascular endovascular angioplasty. The results of the study will enable us to identify patients at high risk of development of CIN, thus appropriate measures can be initiated early and help with their recovery process.

This prospective study aims to investigate the role of IR-Seq in the diagnosis and disease monitoring in patients with IgA nephropathy.

Currently, there is no robust evidence about how women with Chronic Kidney Disease (CKD) perceive pregnancy risk. The aims of this research are to understand women with CKD's perception of risk in pregnancy. In order to provide appropriate pre-pregnancy and antenatal counselling including accurate presentation of risk of pregnancy outcomes, it is important to establish how do women with CKD perceive their risk in pregnancy. In addition, to facilitate discussion about pregnancy for women with CKD, it is critical to understand key psychosocial factors influencing their risk perceptions. This study will be conducted in two phases. In phase one, risk perceptions in women with CKD who are contemplating pregnancy will be quantitatively measured with potential influencing psychosocial factors including their illness perceptions, quality of life, anxiety, depression and perceived social support. Demographic, pregnancy-intentions, medical and pregnancy histories will also be collected. Phase one findings will establish to what extent do women with CKD perceive their pregnancy risk. In phase two, perception of risk, pregnancy intention and behaviour, will be qualitatively explored in women with CKD who perceive high and low degrees of risk. This sub-study will facilitate understanding about which factors and experiences impact risk perception and their relationship with pregnancy intentions and behaviour.

Inflammation begins during early stages of CKD in which neutrophil counts are increased, whereas lymphocyte counts are decreased during inflammation. In addition to known conventional indications of inflammation such as C-reactive protein (CRP), fibrinogen, erythrocyte sedimentation rate, several interleukins and tumor necrotizing factor alpha, Neutrophil-to-lymphocyte ratio (NLR) has increasingly been reported as a measure of systemic inflammation (Okyay G U et al 2013 and Yilmaz G et al ,2017) Several recent studies have shown that mean platelet volume (MPV) is also increased during inflammation and may be associated with poorer prognosis in CKD (Yilmaz G et al ,2017).

A registry of consecutive patients who were admitted and diagnosed with acute myocardial infarction or acute cerebral infarction were conducted at the Guangdong General Hospital or the First Affiliated Hospital of Guangzhou University of Chinese Medicine, Yue Bei People's Hospital, China, between January 2000 and December 2016. The adverse clinical outcomes, including all-cause mortality, were followed from the date of admission for acute myocardial infarction or acute cerebral infarction until study end (December 31, 2016). All-cause mortality, including the date of death, was identified from the electronic hospitalization data, phone follow-up, and confirmed by the household registration (HUKOU) system, a record of registration required by law in China. Baseline characteristics, including major treatment of acute myocardial infarction or acute cerebral infarction, estimated glomerular filtration rate (eGFR) and proteinuria, were collected. Demographic data were determined from the electronic hospitalization data and electronic hospital discharge records. All comorbid conditions were identified using International Statistical Classification of Diseases, Tenth Revision (ICD-10), coding algorithms applied to electronic physician claims and electronic hospital discharge records. Life style (smoking), treatment regimen at discharge, including angiotensin-converting enzyme inhibitor (ACEI), angiotensin II receptor blocker (ARB), were determined from the electronic hospitalization data.

This 3-year study will systematically evaluate the prevalence, clinical symptoms, and progression of CV and kidney disease and assess the impact of potential genetic, pharmacological, behavior, and environmental risk factors in a prospective cohort with a sample size of 125 aged 3-18 years children with stage G1-G4 chronic kidney disease (CKD). Measurements of morphological (e.g., LVMI & cIMT) and functional characteristics (e.g., FMD & PWV) of the cardiovascular system and 24hr ABPM profile will serve as surrogate end points for CV comorbidity in this study. Possible associations of these end points with multiple molecular (ADMA & urine exosome miRNA), perceived value and behavior (EQ-5D-Y), pharmacological (NHIRD and CGRD), and environmental risk factors (patient and family survey) will be explored.

The purpose of this study is to learn more about how to identify signs of early chronic kidney diseases in children who were born prematurely with low birth weight (less than 3 ½ pounds). Researchers plan to compare the kidney function in children who experienced acute kidney injury (AKI) in the Neonatal Intensive Care Unit (NICU) with those who did not experience it. Evidence from several studies and our experience at UVA show that older children who experienced AKI while in the Pediatric Intensive Care Unit (PICU) have increased risk of developing early chronic kidney disease, and they also show early changes in the urine and blood that is consistent with early chronic kidney disease. In this study, the investigators hope to determine if any of these changes can be detected in early childhood, and if so, at what age we can start detecting these changes.

Quantification and preferential sites of arterial wall calcification within the coronary and lower legs arteries will be comared between Pseudo-Xanthoma elasticum(PXE) atients and type 2 diabetics and Chronic Kidney disease.

The goals of the KNOW-CKD (KoreaN cohort study for Outcome in patients With Chronic Kidney Disease) study are 1) to establish a CKD cohort representing Korean CKD population for up to 10-year follow-up, and 2) to investigate the renal progression, mortality, complications, risk factors, role of biochemical parameters and the genetic influence. KNOW-CKD Research Group comprises nephrologists, pediatric nephrologists, epidemiologists and statisticians from eleven centers in Korea. KNOW-CKD will enroll 2,850 individuals with CKD stage from 1 to 5 between 2011 and 2015 and follow them up to 10 years. Dialyzed patients or those with allograft kidney are excluded. At enrollment and at pre-specified intervals, laboratory tests will be conducted on the kidney function, biochemical profiles, anemia, cardiovascular complication (echocardiography, coronary CT, arterial stiffness), and mineral bone disorder. A biobank is also established for the DNA, serum and urine at regular interval. Information on the medical history, health questionnaires, QoL will also be collected. Web-based case-report forms (CRF) is developed for the systemic management of the patient data.

Fabry Disease (FD) is a rare genetic lysosomal storage disease including an X-linked mutation and characterized by an alpha-galactosidase A (GLA) deficiency. It causes globotriaosylceramide (GB3) accumulation within blood vessels, tissues and organs. This accumulation leads to multisystemic deficiency, such as progressive kidney insufficiency. Due to its low prevalence and non-specific symptoms, FD is under-diagnosed. Its estimated incidence is ranged from 1/40,000 to 1/120,000 live births. A review of the international literature suggests a higher prevalence among dialysis patients. Its diagnosis could lead to an enzyme replacement therapy, in order to avoid the occurrence or aggravation of other organs irreversible lesions, and to enhance the familial screening. We aim to conduct a multicentric cross-sectional prevalence study in 5 areas (Rhône-Alpes-Auvergne, Ile de France, Aquitaine, Picardie and department of Gard), involving biologic collection and genetic diagnosis test. Our objective is to measure the prevalence of FD among dialysis patients. Eligible patients will be included after signing the informed consent. In the five participating areas, all of the dialysis centers will be asked for involvement. Nominative data of the French renal epidemiology and information network (REIN) registry will enable first patients screening for eligibility among prevalent dialysis patients. If needed (insufficient or absent data in the REIN registry), data will be completed with medical files. A blood drop will be collected during a hemodialysis session (or the monthly test for peritoneal dialysis treated patients) and deposited on an anonymized blotting paper. For the diagnosis of FD, men will have a measure of the alpha-galactosidase activity, whereas screening in women will be established on the association of alpha-galactosidase activity and lyso-GB3 analysis. If results are compatible with FD, genetic mutation will be search in order to confirm the diagnosis for women, and, for all, to offer familial testing. Results will be transmitted to the nephrologist within the next 2 to 9 weeks. Patients diagnosed with FD will be managed in accordance with the guidelines of the French National Authority for Health (F.N.A.H.).
