Hypertension in acute neurological diseases of childhood
Insights
Acute neurological disease can cause hypertension in children. Intravenous diazoxide is effective for managing these acute hypertensive episodes, potentially linked to brain stem pathway disruption.
Area of Science:
- Pediatric Neurology
- Cardiovascular Physiology
Background:
- Hypertension in children is often secondary to underlying conditions.
- Acute neurological events can precipitate significant physiological changes.
Observation:
- Five pediatric cases of hypertension associated with acute neurological disease were analyzed.
- Clinical presentations and neurological deficits were documented.
Findings:
- Hypertension may result from disrupted brain stem pathways affecting baroreceptor and osmoreceptor integration.
- Autonomic dysfunction is a potential mechanism in these cases.
Implications:
- Understanding these mechanisms is crucial for diagnosing and managing neurological-induced hypertension in children.
- Prompt and effective pharmacological intervention, such as diazoxide, is vital for acute episodes.
Abstract:
Five children are described who developed hypertension in relation to acute neurological disease. Possible pathophysiological mechanisms for the hypertension are considered. It is thought that the hypertension may have been related to interruption of the ascending tracts in the brain stem, leading to failure of integration between, or independent action of, the baroreceptors and osmoreceptor system. Management and treatment are discussed. Diazoxide (5 mg/kg bodyweight, given intravenously) appears to be the most effective drug for use in the acute episodes.
