We are looking for patients with kidney disease and healthy controls (no kidney disease) to provide blood samples, fill out surveys, and provide health related information to help investigators learn more about how to better diagnose and treat kidney disease. The information you provide will go into a "library" of data for doctors and researchers across the world to use for research projects. If you are a kidney patient, we are able to use your information to find out if you are eligible for treatment studies/other studies in the future.

The purpose of this study is to learn more about three kidney diseases called nephrotic syndrome: Focal Segmental Glomerulosclerosis (FSGS), Minimal Change Disease (MCD), and Membranous Nephropathy (MN). By collecting health information and laboratory samples from individuals who have these diseases and by making this information available to researchers, we hope to gain new knowledge about these diseases and to find better treatments for them.

Liver injury due to prescription and non-prescription medication is medical, scientific, and public health problem of increasing frequency and importance in United States. Drug-induced liver injury (DILI) is the most common reason the Food and Drug Administration (FDA) would choose not to approve a new drug or withdraw a drug from the market. However, drug-induced liver injuries are often under-reported and difficult to detect/diagnose. This study seeks to learn more about these drug-induced liver injuries and develop better ways to detect, define, and study drug-induced liver injuries. The study will be looking at new cases of drug-induced liver injury, as well as gathering data on previous drug-induced liver injury (up to January 1, 1994).

About two in five people who are undergoing a kidney biopsy have diabetes. Diabetes is a common finding in people with kidney disease, but little is known about the specific ways in which diabetes affects kidney function. The purpose of this study is to gather two groups of patients with diabetes who undergo a kidney biopsy in order to create a source of information with genetic, blood, and urine samples available, by which researchers can study how diabetes affects kidney function.

Infections occurring in individuals with glomerular disease are preventable contributors to excess healthcare utilization, morbidity, and mortality, and are the leading cause of death in children with glomerular disease. Vaccination is a powerful and cost-effective method to attenuate infectious burden, and clinical guidelines recommend that patients with glomerular disease receive 23-valent pneumococcal (PPSV23) vaccine. The main objective of the study is to determine functional PPSV23 immunogenicity in a prospectively collected multicenter cohort of children with idiopathic nephrotic syndrome using measurements of anti-pneumococcal and opsonophagocytic antibody titers prior to, and 1, 3 and 12 months following PPSV23 vaccination.

This research is studying the JuxtaFlow® Renal Assist Device (JuxtaFlow® RAD), to determine whether it enhances kidney function in patients with kidney function problems who are having a heart operation that requires a heart-lung machine. This device is investigational, which means it is not approved by the (Food and Drug Administration) FDA. However, the FDA or regulatory body has approved the clinical use of this device in this research study.

This study is comparing two approaches for monitoring and addressing symptoms among adult patients with kidney failure who are treated with hemodialysis. For the first approach patients use an electronic system twice a month to report their symptoms. The system sends alerts to their medical team at the dialysis clinic about the reported symptoms and gives suggestions about how to manage them. The system also provides reports that show patients and their medical team the reported symptoms over time. For the second approach patients complete a quality of life questionnaire that includes questions about symptoms once a year. The questionnaire does not have follow-up support like alerts, symptom management guidance, or reports. In addition, researchers will talk to patients, dialysis clinic personnel, and medical providers about their experiences using the electronic symptom monitoring system to learn about how to best use patient-reported outcome measures in dialysis care.

The purpose of this study is to understand how body fat and skeletal muscle in your body impacts your heart, kidney, and metabolic health. This research may help to better diagnose and treat patients and prevent progression of cardiovascular-kidney-metabolic diseases.

We have created this registry to provide an opportunity to study diagnostic capabilities, administration protocols and long-term effects of contrast-enhanced ultrasound (CEUS) of any organ.

We are collecting data on children living with chronic kidney disease, including children on dialysis or with a kidney transplant, to learn more about what happens over time. The data collected will be used for research projects.
