Summary
Hemolytic-uremic syndrome (HUS) can cause severe neurological issues in children, including abnormal movements. Intracerebral microangiopathy is the likely cause, with potential for recovery.
Area of Science:
- Pediatric Neurology
- Nephrology
- Neuroscience
Background:
- Hemolytic-uremic syndrome (HUS) is a serious condition often associated with gastrointestinal infections.
- Neurological complications in HUS can significantly impact patient prognosis and require intensive management.
Observation:
- Two pediatric HUS patients presented with altered consciousness and severe striatal-related abnormal movements.
- These children required dialysis and mechanical ventilation due to the severity of their condition.
Findings:
- Neurological dysfunction was attributed to intracerebral microangiopathy, excluding hypertension or metabolic disturbances.
- Cerebral blood flow studies supported the microangiopathy hypothesis.
- Neuropathology in HUS patients with CNS symptoms revealed CNS vascular thromboses and basal ganglia infarcts on CT scans.
Implications:
- Intracerebral microangiopathy is a key pathogenic mechanism for neurological dysfunction in HUS.
- While severe CNS involvement worsens HUS prognosis, abnormal movements may resolve without lasting deficits.
- Early recognition and management of neurological symptoms in HUS are crucial for patient outcomes.
