[Causes of death in congenital hypothyroidism. An autopsy study]
Insights
Congenital hypothyroidism can lead to unexpected deaths in children, often due to complications like bronchoaspiration or heart failure, especially with delayed diagnosis and treatment.
Area of Science:
- Pediatric Endocrinology
- Neonatal Health
- Pathology
Background:
- Congenital hypothyroidism (CH) is a condition where infants are born with an underactive thyroid gland.
- Untreated CH can lead to severe developmental issues and increased mortality.
- Unexpected deaths in infants with CH suggest a need to investigate underlying causes.
Purpose of the Study:
- To investigate the causes of death in children diagnosed with congenital hypothyroidism.
- To determine if delayed diagnosis and treatment correlate with unexpected mortality.
- To identify common autopsy findings in deceased infants with CH.
Main Methods:
- A case series of sixteen consecutive pediatric autopsies was reviewed.
- Patients with confirmed congenital hypothyroidism were analyzed.
- Autopsy findings were examined to determine primary and contributing causes of death.
Main Results:
- Four patients with CH died undiagnosed and untreated.
- Twelve patients had documented CH with diagnosis after two months of age.
- Nine of sixteen children (56%) died unexpectedly, with autopsy findings suggesting bronchoaspiration (5 cases) and heart failure (4 cases).
- Seven cases died from predictable severe infections.
Conclusions:
- Delayed diagnosis and treatment of congenital hypothyroidism increase the risk of unexpected death.
- Bronchoaspiration and heart failure are significant causes of mortality in infants with CH.
- Early diagnosis and timely treatment are crucial for preventing mortality in children with CH.
Abstract:
Children with congenital hypothyroidism are prone to die unexpectedly. In order to test this hypothesis, the primary and contributing causes of death were studied in a case series of sixteen consecutive children coming to autopsy. Four patients with absent thyroid died undiagnosed and untreated. The remaining twelve cases had documented hypothyroidism with low T3 and T4 levels. Diagnosis was established after the age of two months. Nine of the sixteen cases died unexpectedly, three while in the hospital and six at home. Autopsy findings suggested bronchoaspiration in five and heart failure in four. The remaining seven cases died under predictable circumstances with serious infections. Children with congenital hypothyroidism with delayed treatment may die unexpectedly as a result of the organic dysfunction caused by their primary disease.
