Fatal heat-stroke in a child taking appetite-suppressant drugs
Insights
Appetite suppressants containing sympathomimetic amines can cause heat intolerance. An 11-year-old girl experienced heat stroke during a hike due to these medications.
Area of Science:
- Pediatrics
- Environmental Medicine
- Pharmacology
Background:
- Weight-reducing regimens in children require careful monitoring.
- Appetite suppressants, particularly sympathomimetic amines, are sometimes used.
- Understanding medication side effects in diverse environmental conditions is crucial.
Observation:
- An 11-year-old girl developed heat stroke during a nature hike.
- The ambient temperature was 34 degrees C.
- The patient was taking two appetite-suppressant agents for weight reduction.
Findings:
- Sympathomimetic amines increase endogenous heat production via central nervous system stimulation.
- These agents impair heat dissipation through peripheral vasoconstriction.
- The patient's condition was likely exacerbated by medication-induced heat intolerance.
Implications:
- Physicians should consider environmental factors when prescribing appetite suppressants.
- Heat intolerance is a significant risk associated with sympathomimetic amine use.
- Pediatric weight management strategies must prioritize patient safety and avoid adverse drug reactions.
Abstract:
An 11-year-old girl who was taking two appetite-suppressant agents as part of a weight-reducing regimen developed heat-stroke while taking part in a 'nature hike' at an ambient temperature of 34 degrees C. The other 107 participating children suffered no significant ill-effects. Sympathomimetic amines used as appetite suppressants can produce heat intolerance by two mechanisms: they increase endogenous heat production as a result of their stimulatory effects on the central nervous system, and they impede the dissipation of heat from the body by producing peripheral vasoconstriction.
