Filter by:A new study have shown that high nighttime blood pressure (BP) and/or non-dipping (lack of fall in blood pressure during nighttime) is a strong predictor for the risk of cardiovascular disease and mortality in patients with hypertension. Three factors seem to affect the night time blood pressure: chronic kidney disease, obstructive sleep apnea (OSA) or the way ambulatory blood pressure is monitored. The aim of this study is to analyse the importance of these three factors on nighttime bloodpressure. Hypothesis: Central 24 hour blood pressure monitoring provides another measure of daily fluctuations in blood pressure than peripheral 24 hour blood pressure monitoring, because measurement is painless and does not interfere with activities during the daytime or night-time sleep In chronic kidney disease and OSA the decrease in nocturnal BP is lower than in healthy subjects. In chronic kidney disease the decrease in the nocturnal BP is inversely correlated to the severity of OSA, the severity of kidney disease, and blood pressure during daytime.
This is an open label clinical study designed to evaluate the safety and immunogenicity of Sci-B-Vac Hepatitis B Vaccine compared to Engerix-B Hepatitis B Vaccine in dialysis patients. The study hypothesis is that vaccination with Sci B Vac will achieve a higher seroprotection rate and a higher anti-Hepatitis B surface antibody serum titer level than vaccination with Engerix-B Dialysis patients will be categorized as "naïve" or "previously vaccinated" and each group will be randomized to treatment. Naïve patients randomized to Sci-B-Vac Hepatitis B vaccine will receive vaccination in three doses, 10 μg each, at 0, 1, and 6 months, or Engerix-B Hepatitis B vaccine given in four doses, 40 μg each, at 0, 1, 2, and 6 months. Previously vaccinated patients randomized to Sci-B-Vac Hepatitis B vaccine will receive vaccination in three doses, 20 μg each, at 0, 1, and 6 months, or Engerix-B Hepatitis B vaccine given in four doses, 40 μg each, at 0, 1, 2, and 6 months. All vaccines will be administered via intra-muscular injection to the deltoid muscle. The study will consist of three periods: a screening period of up to four weeks, a 24-week open-label treatment period, and a 24-week safety follow-up period. The total expected duration of the study per subject is 52 weeks as follows: Screening period: approximately 4 weeks; treatment period: 24 weeks; and follow up period: 24 weeks. The primary endpoint is the by-vaccine difference in the proportion of subjects attaining seroprotective immune response (anti-Hepatitis B surface antibody ≥ 10 IU/mL) 4 weeks after the last vaccination with either Sci-B-Vac or Engerix-B. Secondary endpoints include anti-Hepatitis B surface antibody geometric mean concentrations calculated for all subjects upon last active dose; the proportion of subjects with anti-Hepatitis B surface antibody concentrations equal to or above 10 IU/mL for all subjects at 12 weeks following the first vaccine dose; the by-treatment difference in serum titer levels of anti-Hepatitis B surface antibodies at 12, 24 and 52 weeks following the first vaccination. A by-vaccine comparison of adverse events will also be performed.
The purpose of this research study is to study the effects of paricalcitol on endothelial function and inflammation, cardiovascular risk factors which are associated with patient populations that have Type 2 diabetes and Stage 3 and 4 Chronic Kidney Disease (CKD). Hypothesis 1: The state of CKD is associated with oxidative stress and inflammation and impaired post ischemic endothelium dependent flow mediated vasodilation which may contribute to atherogenesis. Hypothesis 2: The administration of paracalcitol to patients with CKD will suppress oxidative stress and inflammation and improve endothelial function and thus contribute to an anti-atherogenic action.
Chronic kidney disease (CKD) affects up to 16% of the adult population and is associated with significant morbidity and mortality. People at highest risk from progressive CKD are defined by a sustained decline in estimated glomerular filtration rate (eGFR) and/or the presence of significant albuminuria/proteinuria. Accurate mapping of the bio-clinical determinants of this group will enable improved risk stratification and direct the development of better targeted management for people with CKD. To address these requirements we have established the Renal Impairment in Secondary Care (RIISC) study; RIISC is enrolling a cohort of patients at high risk from progressive CKD and compiling a comprehensive and detailed bio-clinical phenotype, including vascular and oral health phenotyping, at enrolment and on subsequent follow-up.
Kidney disease is a common problem after heart transplantation. It may be caused by anti-rejection medications such as cyclosporine or tacrolimus. However, the reason why some people develop kidney problems after a heart transplant, but other people do not, is not fully known. This study plans to learn more about the relationship between a person's genetic make-up (DNA; deoxyribonucleic acid) and the risk of kidney problems after a heart transplant. The long-term goal of this research is to identify genetic variations that may help predict the development of kidney problems after heart transplantation.
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.
End-stage renal disease (ESRD) presents a heavy burden on a patient's psychological and social life, as well as overall quality of life (QoL). Health-related quality of life (HRQoL) in dialysis patients measures the physical, social or emotional well-being that is affected by ESRD and/or its treatment, and has been increasingly used as an outcome measure in interventional studies. Additionally, associations between social support and QoL have been observed, indicating that improved social support could improve HRQoL, morbidity and mortality in ESRD patients. However, it is not clear if hemodialysis (HD) and peritoneal dialysis (PD) have different impacts on HRQoL. Furthermore, comparisons of HRQoL and social support between HD and PD patients in the multiethnic society of Singapore have not been evaluated. As such, the investigators propose to conduct this cross-sectional study in the investigators local multiethnic ESRD patient population to evaluate and compare patient-reported outcomes (HRQoL and social support), economic and clinical laboratory outcomes in HD and PD patients. All chronic HD and PD patients seen in NUH outpatient renal or PD clinic will be included in this cross-sectional, observational study. Information on patient demographics, medical/medication histories, dialysis vintage, clinical laboratory data and associated medical costs will be obtained from clinic notes, electronic medical records and hospital databases. Patient-reported outcomes will be determined from scores of the Kidney Disease Quality of Life-Short Form, EuroQol 5 Dimensions, Family Functioning Measure, Oslo-3 Social Support Scale, Multidimensional Scale of Perceived Social Support, Kessler Psychological Distress Scale and Health Services Utilization questionnaires (for indirect costs), and compared between HD and PD patients. Results from this study will provide important HRQoL information to assist renal physicians and patients to make treatment decisions. Furthermore, intervention programs could be developed to improve social support based on patients' needs. These could in turn improve patients' HRQoL, morbidity and mortality outcomes with minimal risks involved.

To determine whether or not chronic kidney disease (CKD), stages III—V and ESRD , is associated with altered vitamin D metabolism related to fibroblast growth factor-23 (FGF-23) stimulation of Cyp24 and whether they have resistance to elevations of 25 Hydroxyvitamin D (25(OH)D3) after cholecalciferol supplementation. To determine if such resistance is related to enhanced catabolism of (25(OH)related to elevated levels of FGF-23.
This project expects the integrated database of terminally renal ill patients combines clinical and files of Health Insurance and renal medical society database. It will provide valuable actual evidence data to quality monitoring of dialysis treatment and related academic research. Besides, using the cohort study of chronic renal disease --「epidemiologic research of chronic renal disease」, we can trace the patient continually and analysis different risk factors of chronic renal disease in Taiwan. Taken together, the results of this project --1.1「Integrate the current database of renal disease and establishment of national monitor system」and 1.2「Epidemiologic study in chronic renal disease」-- will provide the basic rules of prevention and treatment, basic research and clinic application in chronic renal disease.
