Encephalopathy in children with chronic renal failure
Insights
This study investigated a rare encephalopathy in children with chronic renal failure, finding that aluminum or calcium toxicity likely does not cause this neurological disorder.
Area of Science:
- Pediatric Nephrology
- Neurology
- Biochemistry
Background:
- Progressive encephalopathy is documented in adults on maintenance hemodialysis.
- A similar condition was observed in two pre-dialysis children with chronic renal failure.
Observation:
- Both children presented with severe hyperparathyroidism and persistent hypercalcemia requiring parathyroidectomy.
- One child showed slight improvement post-surgery.
Findings:
- Biochemical analyses of serum and brain tissue were compared between affected children and neurologically healthy controls.
- Results indicate that aluminum or calcium toxicity is unlikely to be the cause of this encephalopathy.
Implications:
- This research helps differentiate the etiology of encephalopathy in pediatric chronic renal failure.
- It suggests further investigation into other potential neurotoxic factors or underlying mechanisms is warranted.
Abstract:
Progressive encephalopathy with characteristic clinical features and electroencephalographic findings has been reported many times in adult patients treated with maintenance hemodialysis. Two children with chronic renal failure developed a similar encephalopathy prior to their second birthdays and before the initiation of dialysis. Both children required parathyroidectomy for control of severe hyperparathyroidism with persistent hypercalcemia. Slight improvement followed this procedure in one patient. Selected biochemical abnormalities in serum and in brain tissue specimens were compared to those of neurologically unaffected children. Results of thes studies suggest that a direct toxic effect of either aluminum or calcium on the brain does not play an etiologic role in this disorder.
