Primary hyperparathyroidism in young adults.

OBJECTIVES

The purpose of this study was to compare the incidence of multiglandular disease and rate of treatment failure between younger and older patients with primary hyperparathyroidism.

STUDY DESIGN AND

SETTING

The medical charts of patients who underwent surgery for primary hyperparathyroidism at our tertiary-care institution between 1995 and 2001 were reviewed.

RESULTS

Three hundred nineteen patients were identified, of whom 33 were aged 40 years or less. There were no statistically significant differences between the younger and older groups in the incidence of multiglandular disease (9.1% for both, P = 1.00) or in the treatment failure rate (12.1% and 8%, respectively, P = 0.43). Sonography was significantly more sensitive than technetium Tc-sestamibi in the younger group (96% vs 57%, P < 0.05). Parathyroid hormone level and gland weight were significantly higher in the older group (P = 0.004).

CONCLUSION

Our results suggest that the same treatment strategy should be applied to all patients with primary hyperparathyroidism. Ultrasound appears to be the localization procedure of choice in younger patients.
