Monitoring patients after islet transplant failure

Long Term Surveillance of Islet Transplant Recipients Following Complete Graft Loss

Observational University of Miami · NCT02000687

This study looks at patients who have lost their islet transplant for Type 1 Diabetes to see how stopping their immune-suppressing medications affects their antibody levels over the next 10 years.

What this trial studies

This observational study focuses on patients who have experienced complete graft loss following islet transplantation for Type 1 Diabetes Mellitus. After confirming graft loss, the study will discontinue the patients' immunosuppressive medications and monitor them for 10 years. The primary goal is to assess the rate of allosensitization by measuring panel reactive antibody (PRA) levels at specified intervals. The study aims to understand the persistence of elevated PRA levels and the implications for future transplants.

Who should consider this trial

Good fit: Ideal candidates are individuals with a history of at least one islet transplant who have experienced complete graft loss.

Not a fit: Patients who have undergone any solid organ transplant or are unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the immune response of patients after islet transplant failure, potentially guiding future transplant strategies.

How similar studies have performed: While there may be limited studies specifically focused on long-term outcomes after islet graft loss, similar approaches in transplant immunology have shown promise in understanding allosensitization.
