Immunosuppression in children with primary mitochondrial diseases after kidney transplantation: insight from case series of RMND1-related disease

While successful kidney transplantation has been reported in pediatric patients with primary mitochondrial diseases, immunosuppression regimen and its effect on systemic disease were not described. We present four pediatric patients with genetically confirmed RMND1 disease in a quaternary nephrology center. They presented at a very young age and progressed rapidly to stage 5 chronic kidney disease. All underwent successful kidney transplantation. Their allograft function remained stable throughout the follow-up period, and they did not manifest any major systemic deterioration.
