Official title
Post-transplant Lymphoproliferative Disorder Following Kidney Transplantation in Denys-Drash Syndrome: a Case-control Study
Overview
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.
Detailed description
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.
Interventions
