Purpose: Primary hyperparathyroidism has been studied more extensively in adults than in adolescents. The objective of this study is to define the similarities and differences that exist between these groups.
Methods: A retrospective review of 1,000 primary hyperparathyroidism patients undergoing parathyroidectomy at a single tertiary-care university teaching hospital between 1990 and 2004. All patients 20 years of age or younger comprised our study cohort, and were compared to two historical adult groups.
Results: Of 1,000 parathyroidectomies, 21 (2.1 %) were 20 years of age or younger (adolescent). The adolescents presented with higher serum calcium levels (p < 0.01) more severe symptoms (p = 0.02), more renal stones (p = 0.048), and a higher incidence of hypercalcemic crisis (p = 0.02), when compared with adults. We found that 67 % suffered from a triad of tiredness, weakness, and depression versus 39 % of adults (p = 0.02). Sestamibi scans were less helpful in the adolescents than in adults. Similar to the adults, 86 % of adolescent patients had single gland disease, and 95 % were cured at the first operation.
Conclusion: Adolescents with primary hyperparathyroidism typically have more severe disease than adults. Contrary to popular belief, most adolescents have single gland disease and not hyperplasia associated with a genetic disorder.
