Cardiovascular disease (CVD), chronic kidney disease (CKD), diabetes mellitus (DM) and HIV infection are long-term conditions (LTC) with major health implications for people of African ancestry. These LTC often arise in the setting of an adverse demographic, social, biologic and genetic environment, although this remains poorly understood. The investigators plan to conduct a comprehensive syndemic evaluation in individuals with and without CVD, CKD and DM in people of African ancestry with HIV to obtain novel insights into the development of LTC in this population. In addition, the investigators will conduct focus groups to explore the role of syndemic factors in the development of LTC and develop and pilot an educational programme to improve knowledge about LTC in the African/Caribbean community.

Patients with end-stage renal disease are most vulnerable in the early months following hemodialysis (HD) initiation. Data from the United States Renal Data System and Singapore Renal Registry showed high mortality rates in the first 3-12 months of dialysis. Comprehensive multidisciplinary intervention programs implemented in the initial 3-4 months of dialysis showed reduction in mortality and morbidity in incident dialysis patients in the United States. Based on these models, the Hemodialysis Initiation and Transition (HIT) Clinic involving a renal physician, clinical pharmacist and coordinator was set up. The main aim of the clinic is to provide multidisciplinary, intensive and consistent care to patients in the first 3 to 4 months after HD initiation to focus on and streamline the management of dialysis issues and complications. These interventions would help patients achieve goal therapeutic targets, as well as reduce hospitalization rates and mortality, thereby improving their clinical outcomes and self-reported quality of life, and could result in economic and cost savings for the patients and healthcare system. The purpose of this study is to determine if the multidisciplinary, intensive and collaborative management of our multiethnic Asian patients newly-initiated on HD improves laboratory, clinical, economic and patient-reported outcomes. Adult incident HD patients from NUH will be randomized to the HIT clinic or to conventional management. Information on demographics, medical/medication histories, laboratory data (dialysis adequacy, iron-deficiency anemia, mineral/bone disorder, malnutrition and diabetes), hospitalizations, deaths and medical costs will be obtained and compared between the 2 groups. Patient-reported outcomes will be measured using the Kidney Disease Quality of Life-Short Form, EuroQol 5 Dimensions, Family Functioning Measure, Oslo-3 Social Support Scale and Health Services Utilization questionnaires. Data collection will take place at baseline, 3 to 4 months and 12 months after the first visit, with a total study duration and follow-up period of 1 year.

Peritoneal dialysis, known as p- dialysis (PD), is a dialysis form in which the blood is purified by using the body's peritoneum. PD dependents on good access to peritoneum. For this, a catheter is implanted in the peritoneum and tunneled 2-3 cm below the skin. The way out is called exit site and is close to the navel. Patients are selected at random to use bandage or not use bandage for three months, then cross-over. The overall objective of the research is that the patient in PD maintains a complete and healthy skin without signs of infection around the exit site. In the study effects by omission of bandage over exit site at patients in PD are examined when the patients are in a stable process with PD. The patient's exit site is assessed according to skin character and examined for infection. The hypothesis is that there is no greater rate of infection in patients without bandage than in patients with bandage over the exit site, and that patients without bandage will have stronger skin around exit site.

Background： The prevalence of chronic kidney disease (CKD) is high in Taiwan. Though there are many factors that may affect the measurement of serum creatinine, it is a well-accepted marker for renal function assessment. The creatinine clearance (ClCr) estimated by Cockcroft-Gault is commonly used as a reference for dosage adjustment; while the estimated glomerular filtration rate (eGFR) by Modification of Diet in Renal Disease (MDRD) is used in CKD staging. ClCr and eGFR not only have different units, but the results of estimation from the two varied among races and individuals. Since 2010, US Food and Drug Administration required both the influences of ClCr and eGFR on the pharmacokinetics of a drug in renal insufficient patients during pharmacokinetic studies. Because most drugs are excreted through kidney, an understanding on the relationship between ClCr and eGFR is important to dose safely and effectively. Furthermore, identifying the factors that may influence the difference between ClCr and eGFR can provide in-depth consideration during clinical renal function assessment. Purpose： The purpose of this study is to analyze the correlation between different ClCr and eGFR equations in order to provide better renal dose. We also want to find the factors that may cause the differences between them. Methods： This study will conduct literature review to understand study population during the development of different ClCr and eGFR equations, as well as their scope of application. National Taiwan University Hospital electronic patient database will be used to analyze the correlation between ClCr and eGFR and to identify factors that may influence the difference between ClCr and eGFR. The data from patients who have completed 12-hr or 24-hr urine collection with calculated renal function will be used to verify the applicability of these equations (including a ClCr equation developed by our institute) in Taiwanese. Pharmacokinetic principles will be used to analyze the appropriate unit to be used for renal function while dosing a patient.

The purpose of this study is to determine whether L5, one of the Low Density Lipoproteins, is an effective predicting factor for cardiovascular disease in chronic renal and hemodialytic patients.

This study will follow 2500 prevalent Chronic Kidney Disease (CKD) patients with Glomerular Filtration Rate (GFR) from 15-45 ml/min for 30 months with serial measurements every 6 months and subsequent annual chart review up to 60 months. This observational study will analyze the demographics, clinical status, medications and blood and urine samples of these patients and study the conventional biochemical, hormonal and metabolic parameters assessing which underlying biomarkers reflect the processes involved with disease progression.

Chronic kidney disease (CKD) that results in end-stage renal disease (ESRD) is a major international health problem. Many clinical markers such as urine protein or eGFR(evaluated glomerular filtration rate),can estimate the renal function, but not sensitive. As well-known, the crucial role of angiotensin II (AngII), the major effector of the renin-angiotensin system (RAS), in the development of renal fibrosis that results in ESRD is widely recognized.Abundant researches find that intrarenal RAS takes an important role on the progression of CKD. At present, no clinical marker is available to evaluate intrarenal AngII activity because it is difficult to measure it directly in patients. So find and establish a bio-marker of local renal RAS activation maybe a breakthrough in early detection and treatment of CKD. Angiotensinogen(AGT) is the only known substrate for renin and the level of AGT in humans is close to Km value for renin. Thus , changes in AGT levels can control the activity of the RAS, and its up-regulation may lead to activity of Ang levels. Then we hypothesis that the AGT is a early bio-marker of local renal RAS activation as well as CKD.

This study involves Chronic Kidney Disease patients that must choose the type of dialysis therapy they ultimately wish to perform. These patients receive education regarding dialysis types from nurses and Nephrologists at a Kidney Function Program. The investigators have developed a web-based Interactive Health Communication Application that could provide more education and support to patients about their dialysis choices. The investigators will compare patients that will receive usual care dialysis education versus patients that will receive additional education through this web-based application. The investigators feel that this tool may increase the proportion of patients who start home dialysis, which offers advantages such as improvement in quality of life and deceased overall healthcare costs, over hospital hemodialysis.

Sclerostin, the product of the SOST gene, located on chromosome 17, locus q11.2 in humans, was originally believed to be a non-classical Bone morphogenetic protein (BMP) antagonist.Sclerostin was recently identified as a component of parathyroid hormone (PTH) signal transduction. Chronic kidney disease (CKD) is associated with abnormalities in bone and mineral metabolism.New advances in the pathogenesis of renal osteodystrophy (ROD) change the perspective from which many of its features and treatment are viewed. Calcium, phosphate, parathyroid hormone (PTH), and vitamin D have been shown to be important determinants of survival associated with kidney diseases. Now ROD dependent and independent of these factors is linked to survival more than just skeletal frailty.Furthermore, ROD is shown to be an underappreciated factor in the level of the serum phosphorus in CKD. The discovery and the elucidation of the mechanism of hyperphosphatemia as a cardiovascular risk in CKD change the view of ROD. Emerging current data suggests a promising role for serum measurements of sclerostin in addition to iPTH in the diagnosis of high bone turnover in chronic kidney disease-5D patients (dialysis patients). Because of the close relationship between ROD and cardiovascular disease, the aim of this study is to investigate the association between sclerostin, arteriovenous fistula thrombosis, echocardiography and carpal tunnel syndrome in maintenance hemodialysis patients.
