Prospective evaluation of quality of life (SF-36v2) and nonspecific symptoms before and after cure of primary hyperparathyroidism (1-year follow-up)

Background. Only a minority of patients with primary hyperparathyroidism (pHPT) present with the classic symptoms. Most patients have numerous nonspecific symptoms. The aim of this study was to evaluate patients' quality 4 life and nonspecific symptoms before and after cure for pHPT. Methods. This prospective, multicentric study, which took place from May 2003 to September 2004, included 100 patients. Six academic departments of Endocrine Surgery in France participated in the study: the University of Angers, Nancy, Nantes, Marseille, and Poitiers. Only cured patients were included. All patients were given preoperative and postoperative questionnaires (the SF-36v2 Health Survey) at 3, 6, and 12 months to evaluate quality of life and nonspecific symptoms. Results. Preoperatively, the main nonspecific symptoms included the following: anxiety (89%); muscular, bone, or join pain (87%); abdominal distention (82%); forgetfulness (81%); headaches (81%); and mood swings (79%). Quality was significantly improved at 3 and 6 months (P < .05). At 1 year postoperatively, statistically significanly improvement (P < .05) persisted in all 8 domains of the SF-36v2. At 1 year after parathyroidectomy, 5 symptoms remained significantly improved: appetite loss, weight loss, thirst, headache, and nausea. Conclusions. Operative cure of primary hyperparathyroidism significantly improves quality of life and nonspecific symptoms for at least 1 year.
