Hereditary neonatal hyperparathyroidism
Insights
Neonatal primary hyperparathyroidism, a rare condition causing failure to thrive, can be inherited. Early surgical intervention, like parathyroidectomy, is crucial for survival and normal development.
Area of Science:
- Pediatric Endocrinology
- Genetics
- Surgical Oncology
Background:
- Neonatal primary hyperparathyroidism is a severe endocrine disorder often presenting as failure to thrive.
- It can manifest as an autosomal dominant trait, affecting multiple family members.
- Untreated neonatal hyperparathyroidism is frequently fatal.
Observation:
- This report details two brothers diagnosed with neonatal primary hyperparathyroidism.
- Their father also exhibited hyperparathyroidism, strongly suggesting autosomal dominant inheritance.
- Pathological examination revealed chief cell hyperplasia in the parathyroid glands.
Findings:
- One affected brother underwent total parathyroidectomy and has survived for 14 years.
- Near-total parathyroidectomy is identified as the minimum surgical procedure to manage hypercalcemia.
- While permanent hypoparathyroidism can be a consequence, treatment is feasible.
Implications:
- Early diagnosis and prompt surgical management are critical for improving outcomes in neonatal hyperparathyroidism.
- Surgical intervention, particularly parathyroidectomy, can be life-saving.
- With appropriate treatment, affected infants can achieve normal growth and development despite the condition.
Abstract:
Neonatal hyperparathyroidism usually presents as a "failure to thrive" syndrome. It may be transmitted as an autosomal dominant trait and may involve more than one offspring. We report on two brothers with neonatal primary hyperparathyroidism. One underwent a total parathyroidectomy and has lived for 14 years. Hyperparathyroidism was found in their father, suggesting autosomal dominant inheritance. The disease is fatal unless recognized early and treated. The characteristic pathological change is chief cell hyperplasia of the parathyroid glands. Near-total parathyroidectomy is the minimal operation required to control the hypercalcemia. Permanent hypoparathyroidism may be the sequel of appropriate surgical management. Treatment of the totally parathyroidectomized infant, however, is possible and can result in normal growth and development.
