Denys-Drash Syndrome and Risk of Post-transplant Lymphoproliferative Disorder (DRASH-PTLD)
Post-transplant Lymphoproliferative Disorder Following Kidney Transplantation in Denys-Drash Syndrome: a Case-control Study
Denys-Drash syndrome is a rare genetic disorder of childhood characterized by nephrotic syndrome, nephroblastomas, and genital developmental abnormalities. These children present with rapidly progressive renal failure, leading to kidney transplantation at a median age of 3.6 years. In a study of the French cohort of patients with Denys-Drash syndrome, a high risk of lymphoproliferative syndrome was observed (20%). This frequency is significantly higher than in the general transplant population (4%).
The aim of the study is to evaluate the risk of post-transplant lymphoproliferative disorder following kidney transplantation in patients with Denys-Drash syndrome compared to patients with kidney transplant patients without Denys-Drash syndrome.

Descripción detallada
Denys-Drash syndrome is a rare genetic disorder of childhood characterized by nephrotic syndrome, nephroblastomas, and genital developmental abnormalities. These children present with rapidly progressive renal failure, leading to kidney transplantation at a median age of 3.6 years. In a study of the French cohort of patients with Denys-Drash syndrome, a high risk of lymphoproliferative syndrome was observed (20%). This frequency is significantly higher than in the general transplant population (4%).
The aim of the study is to evaluate the risk of post-transplant lymphoproliferative disorder following kidney transplantation in patients with Denys-Drash syndrome compared to patients with kidney transplant patients without Denys-Drash syndrome.
The study hypothesizes that there is an increased risk of lymphoproliferative disorder in children with Denys-Drash syndrome. If this hypothesis is confirmed, it would allow for the development of active treatment methods to combat post-transplant lymphoproliferative disorder in this population.

Patients with Denys-Drash syndrome
Patients who were minors at the time of kidney transplantation between 2000 and 2022.
|
Collection of data from the patient's medical file.
The data will be collected until 2024.
|
|
Control patients
The controls will be matched in chronological order of transplantation with patients with Denys-Drash syndrome: a control before and a control after, matched according to the Epstein-Barr virus status of the pretransplant recipient, the Epstein-Barr virus status of the donor and the age of transplantation.
|
Collection of data from the patient's medical file.
The data will be collected until 2024.
