Health-related quality of life in hyperparathyroidism measurably improves after parathyroidectomy.

BACKGROUND

Hyperparathyroidism is associated with subjective feelings of fatigue and depression as well as limitations in physical activity from musculoskeletal complaints. These quality of life symptoms are not widely accepted as an indication for parathyroidectomy. This study quantifies and compares subjective symptoms of patients with hyperparathyroidism before and after surgery.

METHODS

Between February 2001 and June 2002, 61 patients (14 males and 47 females, mean age of 60.8+/-14.4 years) underwent parathyroidectomy. There were 45 patients with single-gland adenomas, 9 patients with double adenomas, 3 patients with primary hyperparathyroidism from 4-gland hyperplasia, 3 patients with secondary hyperparathyroidism, and 1 patient with tertiary hyperparathyroidism. Patients filled out a 53-question survey based on the Health Outcomes Institute Health Status Questionnaire 2.0 before surgery, 1 month postoperatively, and 3-24 months postoperatively. The survey included questions on overall health, daily activities, mood, and medical conditions. Surveys were analyzed for changes in symptoms attributable to parathyroidectomy. Serum calcium and intact parathyroid hormone levels were obtained preoperatively and at 1- and 3-month follow-up visits.

RESULTS

At both postoperative evaluations, patients' perception of general health, muscle strength, energy level, and mood significantly improved (P<.05). Moreover, there was a significant correlation between the changes in serum calcium and intact parathyroid hormone levels and improvement in symptoms.

CONCLUSIONS

Parathyroidectomy for hyperparathyroidism is associated with significant improvement in patient quality of life. These subjective symptoms represent a valid indication for parathyroidectomy.
