The purpose of the study is to evaluate blood sugar levels and beta-cell function in adolescents and adult with KATP hyperinsulinism whom did not undergo pancreatectomy. We will perform oral glucose tolerance tests, glucose potentiated arginine tests, and evaluate blood sugars in home environment by using continuous glucose monitoring for 10 days.

Dr. Weber at The Children's Hospital of Philadelphia is looking for boys and young men with Duchenne Muscular Dystrophy between 5-20 years old to participate in a study to learn more about bone health. Study participation includes completing two study visits: one baseline visit and one 12-month follow-up visit. To be eligible, participants must have used steroids for a minimum of 12 months by the time they complete their baseline visit. Eligible study participants will be paid for each study visit. If interested in hearing more about this study or being screened for eligibility, please contact Dr. David Weber at davidweberresearch@chop.edu.

This study wants to know about the problems that Black or African American teenagers with type 1 diabetes (T1D) and their families face. It also wants to see how these problems affect their feelings, behavior, and how they get along with others. The study will find out how well they can handle T1D and adapt to it. It will also learn how good things like being strong, family, and where they live might help young people who have to deal with hard things. This includes how well they handle their feelings, behavior, relationships, and T1D care.

The purpose of this study is to evaluate the safety and pharmacokinetics (drug levels in the blood) of teplizumab in children less than 8 years old. The study will also assess if your child stays in Stage 2 T1D or progresses to Stage 3 T1D. Your child may join the study only if they are in Stage 2 T1D. Previous studies in adults and children older than 8 years of age suggest that taking teplizumab, a drug that affects your childs immune system, may stop, delay, or decrease the attack on the cells that make insulin. This slowing or blocking of the immune attack may reduce the risk of short-term and long-term consequences of T1D. To join this study, your child must have been diagnosed with Stage 2 T1D based on two positive T1D-related antibodies and confirmed dysglycemia (abnormal blood sugar levels) based on an oral glucose tolerance test, fasting plasma glucose test, or an increase in a blood test called the hemoglobin A1c. The study is open-label. That means that if your child qualifies for the study, your child will receive teplizumab. There is no placebo in this study.

Our team is working on a study to better understand neurological problems, including seizures and developmental delays, that occur in many individuals with HI/HA syndrome. The study involves a one day visit to The Children's Hospital of Philadelphia and The University of Pennsylvania for a specialized magnetic resonance imaging scan (MRI) of the brain, an electroencephalogram (EEG), blood draw, and completion of questionnaires to evaluate development and behavior. The entire study visit is expected to take about four hours. If you are interested in learning more, please contact us at HIResearch@email.chop.edu.

Insulin therapy, commonly given as multiple daily injection therapy, is the only recommended treatment for Cystic Fibrosis Related Diabetes (CFRD). Traditional therapy for CFRD requires an intense daily effort related to diabetes care on top of the already burdensome management of Cystic Fibrosis. In this study, we will assess the safety and effectiveness of the iLet Bionic Pancreas, an automated insulin delivery system, which uses a continuous glucose monitor (CGM), an insulin pump, and a control formula that activates insulin delivery based on CGM glucose data.
