Encephalopathy in infants and children with chronic renal disease
Insights
Pediatric chronic renal failure can cause encephalopathy with distinct neurological symptoms. Elevated phosphate, alkaline phosphatase, and parathyroid hormone levels were observed in affected children.
Area of Science:
- Neurology
- Nephrology
- Pediatrics
Background:
- Chronic renal failure (CRF) in children can lead to serious complications.
- Encephalopathy is a known complication, but its specific presentation in pediatric CRF requires further elucidation.
Purpose of the Study:
- To describe the neurological manifestations of encephalopathy in pediatric patients with chronic renal failure.
- To identify potential biochemical and electrophysiological markers associated with this condition.
Main Methods:
- Case series examining five pediatric patients with encephalopathy and chronic renal failure.
- Clinical assessment of neurological signs and symptoms.
- Biochemical analysis of serum phosphate, alkaline phosphatase, and parathyroid hormone.
- Serial electroencephalograms (EEGs) to monitor brain activity.
Main Results:
- A consistent pattern of neurological deficits was observed, including ataxia, motor skill loss, myoclonus, seizures, dementia, and bulbar dysfunction.
- Patients with central nervous system (CNS) dysfunction and controls with similar renal failure degrees showed elevated serum phosphate, alkaline phosphatase, and parathyroid hormone.
- Serial EEGs demonstrated progressive cerebral slowing and increased paroxysmal activity in affected patients.
- One patient's autopsy revealed no specific neuropathological findings.
Conclusions:
- Pediatric chronic renal failure-induced encephalopathy presents with a characteristic neurological sequence.
- Elevated phosphate, alkaline phosphatase, and parathyroid hormone may serve as biochemical indicators.
- EEG changes correlate with disease progression.
- Further research is needed to understand the underlying neuropathology.
Abstract:
The examination of five pediatric patients with encephalopathy secondary to chronic renal failure has indicated a stereotyped sequence of neurologic signs and symptoms including ataxia, loss of motor abilities, myoclonus, seizures, dementia, and bulbar dysfunction. Both the patients with CNS dysfunction and a control group selected for a similar degree of renal failure had increased levels of serum phosphate, alkaline phosphatase, and parathyroid hormone. Serial EEGs in the affected group revealed progressive slowing and an increase in paroxysmal features. No specific neuropathologic findings were noted in one patient.
