Convulsions in children undergoing renal transplantation

Area of Science:

• Pediatric Nephrology
• Neurology
• Transplantation Medicine

Background:

• End-stage renal disease (ESRD) often necessitates renal transplantation in children.
• Seizures are a potential complication in pediatric patients with renal failure and post-transplant.
• Understanding seizure etiology and prognosis is crucial for managing these complex cases.

Purpose of the Study:

• To investigate the incidence and characteristics of convulsive seizures in children undergoing renal transplantation.
• To identify the primary etiological factors associated with seizures in this pediatric population.
• To evaluate the long-term outcomes and prognostic indicators for seizures post-renal transplant.

Main Methods:

• Retrospective review of medical records for 154 children who received 207 renal transplants between 1965 and 1987.
• Analysis of seizure occurrence (pre-transplant, post-transplant, or both).
• Correlation of seizure events with underlying conditions, hypertension, and treatment outcomes.

Main Results:

• Convulsive seizures were observed in 48 (31%) of the children.
• Hypertension was identified as the most significant etiological factor for seizures.
• The majority of children experienced minimal long-term problems, with 60% having only a single convulsion.
• Six patients had seizures as a symptom of more severe underlying conditions.
• Rapid seizure resolution after hypertension control was a positive prognostic sign.

Conclusions:

• Hypertension is a critical factor in seizure development among children with renal failure and post-transplant.
• Prompt recognition and management of hypertension are essential for improving seizure outcomes.
• Most children experience favorable prognoses following renal transplantation, particularly when seizures are linked to controlled hypertension.
