If you have been treated with ANCA vasculitis and you are now in remission, you may be able to participate in a study to test if a specific blood test can help your doctor decide if you need maintenance therapy.

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.

A multi-center open-label trial evaluating the efficacy and safety of daratumumab in treatment of patients with proliferative glomerulonephritis with monoclonal immunoglobulin deposits.

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.

Current dialysis vascular access patient education materials can be overwhelming, not written in plain language, and not have enough realistic information about the steps involved in getting a dialysis vascular access before starting hemodialysis. This study is being done to create and test a dialysis vascular access educational video for patients. Participants would take part in a one-time interview about their thoughts on dialysis vascular access education and their ideas for a vascular access video.

To create a biorepository for future research studies to better improve patient treatment in care for patients with liver cancer and liver diseases

The purpose of this IRB approved Humanitarian Use of a device is to allow patients to be treated with LDL-Apheresis, using the LIPOSORBER® LA-15 system. This device is approved for adult and pediatric patients with Focal Segmental Glomeruloslerosis as a Humanitarian Use Device. Its effectiveness has not been demonstrated.

We are surveying individuals with sickle cell disease (SCD) and/or parents of a child with SCD to get a sense of the types of treatment they would choose based on the harms and benefits of those treatment options. The proposed study will be designed to meet the following objectives: 1) Elicit individual respondent's maximum acceptable risk (MAR) for treatment benefits 2) Elicit individual respondent's minimum 3) Characterize heterogeneity in MARs and MABs among respondents
