Follow-up of AKI in Neonates During Childhood Years
Neonatal Acute Kidney InjuryChildhood Chronic Kidney DiseaseThe 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.

Study of the Prevalence of Fabry Disease in French Dialysis Patients
Fabry DiseaseEnd Stage Renal Disease1 moreFabry 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.).

KoreaN Cohort Study for Outcome in Patients With Chronic Kidney Disease : A 10-year Longitudinal...
Chronic Kidney DiseaseThe 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.

CRICKET Study, Coronary Calcium Scores in Patients With Chronic Kidney Disease
Chronic Kidney DiseasePatients with Chronic Kidney Disease (CKD) have been shown to have high coronary calcium scores (CAC), but the temporal association between Glomerular Filtration Rate, CVD risk factors and CAC has not been described. This is a single-center, longitudinal, observational study. Subjects included adults aged 18 years to 65 years old without preexisting coronary artery disease (CAD). The CKD subjects (GFR < 60 ml/min) and the control subjects (GFR >/=60ml/min) were recruited. Laboratory measurements and MDCT scan were performed at baseline and after 12 months. Baseline CAC and average intact parathyroid hormone (iPTH) level were significantly greater in the CKD group. Baseline CAC scores of the CKD group were twice the value of the control group; however, CAC scores over one year were unchanged from baseline.
