Hypertension associated with the Guillain-Barré syndrome
Insights
Guillain-Barré syndrome (GBS) can cause hypertension due to increased renin-angiotensin activity, not just sympathetic hyperactivity. Propranolol effectively managed this hypertension in a pediatric case.
Area of Science:
- Neurology
- Cardiology
- Pediatrics
Background:
- Guillain-Barré syndrome (GBS) is a neurological disorder often associated with hypertension.
- Hypertension in GBS has typically been attributed to sympathetic nervous system overactivity.
Observation:
- A pediatric case of GBS presented with hypertension.
- Urinary catecholamine excretion levels were within the normal range in this patient.
Findings:
- The hypertension in this GBS patient appeared linked to elevated renin-angiotensin system activity.
- Propranolol administration resulted in successful control of the hypertension.
Implications:
- This case suggests that the renin-angiotensin system should be evaluated in GBS patients with hypertension.
- Assessing both the renin-angiotensin system and catecholamine excretion is crucial for managing hypertension in GBS.
- Further research into the mechanisms of hypertension in GBS is warranted.
Abstract:
Guillain-Barré syndrome (GBS) is frequently complicated by hypertension, which has been ascribed to sympathetic nervous system hyperactivity. We report the case of a child with GBS and hypertension that appeared to be related to increased renin-angiotensin activity. Urinary catecholamine excretion was normal. Propranolol therapy successfully controlled the hypertension. Evaluation of the renin-angiotensin system and catecholamine excretion is indicated in patients with GBS and hypertension.
