Surgical options in treating patients with primary hyperparathyroidism.

ABSTRACT: Background Primary hyperparathyroidism is the third most common endocrine disorder for which surgical procedure called parathyroidectomy is the most effective treatment. Since the early 20th century, parathyroid surgery has improved extensively. With the advances in preoperative imaging and with understanding the causes of disease, new and minimally invasive surgical approaches overrode the standard bilateral exploratory operations. Directed parathyroidectomy is currently the standard technique for treatment of primary hyperparathyroidism worldwide. Conclusions Surgery is the only definitive treatment of primary hyperparathyroidism. The most appropriate type of surgical procedure depends on the number and localization of the hyperactive parathyroid glands, availability of modern imaging techniques, limitation of each type of procedure and expertise.

Project description:ImportanceHyperparathyroidism is associated with cardiovascular disease. However, evidence for a beneficial consequence of parathyroidectomy on hypertension is limited.ObjectiveTo investigate if parathyroidectomy improves hypertension in patients with primary hyperparathyroidism (PHPT).Design, setting, and participantsIn this cohort study and retrospective database review, patients with PHPT and hypertension between January 1, 2008, and December 31, 2016, were identified. The mean arterial pressure (MAP) and number of antihypertensive medications were compared between those who did and did not undergo parathyroidectomy. The setting was a large health care system. Primary hyperparathyroidism was defined using biochemical data, and hypertension was identified by International Classification of Diseases, Ninth Revision codes.ExposureParathyroidectomy was identified in the database by Current Procedural Terminology codes.Main outcomes and measuresThe MAP and use of antihypertensive medications were compared for patients who underwent parathyroidectomy and those who did not at 6 months, 1 year, and 2 years. Multivariable logistic regression was used to assess the adjusted odds ratios for both increased and decreased use of antihypertensive medications.ResultsIn this cohort study of 2380 participants (79.0% female), patients undergoing parathyroidectomy (n = 501) were younger (mean [SD] age, 65.3 [9.7] vs 71.9 [10.4] years; P < .001) and took fewer antihypertensive medications at baseline (mean [SD] number of medications, 1.2 [1.1] vs 1.5 [1.3], P < .001) than nonsurgical patients (n = 1879). Patients with parathyroidectomy showed greater improvement in their MAP at all follow-up time points (the median [SD] MAP change from baseline to 1 year was 0.1 [8.7] mm Hg without parathyroidectomy vs -1.2 [7.7] mm Hg after parathyroidectomy, P = .002). Nonsurgical patients were more likely vs those with parathyroidectomy to require more antihypertensive medications at 6 months (15.9% [n = 298] vs 9.8% [n = 49], P = .001), 1 year (18.1% [n = 340] vs 10.8% [n = 54], P < .001), and 2 years (17.6% [n = 330] vs 12.2% [n = 61], P = .004). By multivariable analysis, parathyroidectomy was independently associated with freedom from an increased number of antihypertensive medications at all periods (eg, adjusted odds ratio, 0.49; 95% CI, 0.34-0.70; P < .001 at 1 year). Among patients who were initially not taking antihypertensive medications, patients with parathyroidectomy were less likely vs no surgery to start antihypertensive medication treatment at all periods (eg, 10.2% [13 of 127] vs 30.4% [136 of 447], P < .001 at 1 year).Conclusions and relevanceThis study's findings suggest that, among hypertensive patients with PHPT, parathyroidectomy may be associated not only with greater decreases in their MAP but also with reduced requirements for antihypertensive medications. Parathyroidectomy decreased the number of patients who began taking antihypertensive medications. Additional study will be required to find whether there are downstream cardiovascular benefits of parathyroidectomy. Preexisting hypertension, particularly in those not already taking antihypertensive medications, should be considered when weighing surgical treatment.
