OBJECTIVES: To report our experience with sudden death in children with septo-optic dysplasia and to identify specific risk factors and suggest preventive measures to minimize mortality. METHODS: Clinical data from 5 children with septo-optic dysplasia who died suddenly and unexpectedly were evaluated retrospectively. RESULTS: All children had corticotropin deficiency, all had thermoregulatory disturbances, and 4 children had diabetes insipidus. In at least 4 children, clinical deterioration was caused by fever and dehydration from a presumed viral illness, which appeared to precipitate adrenal crisis. CONCLUSIONS: Children with septo-optic dysplasia and hypocortisolism are at risk for sudden death during febrile illness. Thermoregulatory disturbances and dehydration from diabetes insipidus may potentiate clinical deterioration. Prevention of sudden death in septo-optic dysplasia requires early recognition and treatment of these major risk factors.
