Abstract

Abstract:

Objective To explore the clinical features and prognosis of pediatric papillorenal syndrome (PRS). Methods The clinical data and genetic testing results of two children with PRS admitted to the General Hospital of Ningxia Medical University were analyzed retrospectively. Relevant literatures about pediatric PRS were retrieved and reviewed from the PubMed database, China National Knowledge Infrastructure (CNKI), and Wanfang Data Knowledge Service Platform. Results The two girls with PRS presented growth retardation shortly after birth. They developed unexplained renal insufficiency in early childhood, and rapidly progressed to end-stage renal disease, accompanied by persistent proteinuria. Renal color Doppler ultrasound showed renal atrophy and renal cysts, and renal biopsy pathology indicated focal segmental glomerulosclerosis. Fundus examination revealed optic dysplasia. Next-generation sequencing detected a mutation in the $P A X 2$ gene. Conclusion For children with unexplained renal insufficiency and ocular dysplasia in infancy, active improvement of genetic testing is helpful for the diagnosis, monitoring, and treatment of PRS.

Key words: papillorenal syndrome, renal insufficiency, optic dysplasia, child
