Context: It is unclear whether patients with asymptomatic primary hyperparathyroidism (PHPT) do better with parathyroidectomy (PTx) as compared with conservative medical management. Objective: The aim of the study was to evaluate the beneficial effect of PTx vs. conservative management in patients with mild asymptomatic PHPT. Design: We conducted a prospective, randomized study. Setting: The study took place at a referral center. Patients: We studied 50 patients who did not meet any guidelines for parathyroid surgery as recommended by the National Institutes of Health Consensus Development Conference on Asymptomatic PHPT. Intervention: Patients were randomly assigned to PTx or no PTx and were evaluated at 6 months and at 1 yr. Main Outcome Measures: We compared changes (percentage of basal) of lumbar spine bone mineral density (BMD) between the two groups at 1 yr. Results: The change in BMD at lumbar spine was greater after PTx (+ 4.16 +/- 1.13 for PTx vs. - 1.12 +/- 0.71 for no PTx; P = 0.0002). The change in BMD at the total hip was also significantly greater in the PTx group (+ 2.61 +/- 0.71 for PTx vs. - 1.88 +/- 0.60 for no PTx; P = 0.0001). There was no difference in BMD after 1 yr between both groups at the one-third radius site. In comparison with those who did not undergo surgery, the PTx subjects, after 1 yr, showed significant differences in four quality of life measures as determined by the 36- item short form health survey scale: bodily pain (P = 0.001), general health (P = 0.008), vitality (P = 0.003), and mental health (P = 0.017). Conclusions: In patients with mild asymptomatic PHPT, successful PTx is followed by an improvement in BMD and quality of life. Most patients followed without surgery did not show evidence of progression.
