Higher prevalence of Concomitant Hyperparathyroidism in African American Patients Undergoing Thyroid Surgery

Academic Article

Abstract

  • Background: Hyperparathyroidism (HPT) occurs in about 1% of the general population. Previous studies have suggested that the incidence is higher in those patients with thyroid disease who are undergoing thyroid surgery. The study purpose was to examine the incidence of concomitant HPT in patients already undergoing a thyroid procedure and to identify risk factors. Materials and methods: A prospective database of all patients who had thyroidectomy by the endocrine surgery team was reviewed between August 2012 and April 2020. Per institutional protocol, all patients having thyroid surgery were screened for concomitant hyperparathyroidism. ANOVA/T-Test and Chi-square were conducted to compare those with and without hyperparathyroidism. Results: The median age was 43 and 79% were female. Of the 481 patients undergoing thyroidectomy, 31 (6%) had HPT. The mean preoperative calcium and parathyroid hormone levels were 10 ± 0 mg/dL and 67 ± 5 pg/mL, respectively. When comparing the groups, patients with concomitant HPT were older (53 ± 4 versus 42 ± 1 y, P = 0.005). African American race was a significant risk factor for concomitant HPT. While African Americans represented only 29% of those undergoing surgery, 58% of those with concomitant HPT were African American (P = 0.007). Conclusion: In patients having thyroid surgery, concomitant HPT was present in 6% of the population, higher than estimated general population prevalence. While we understand that primary HPT incidence increases with age, to our knowledge, this is the first report to document that African Americans are at a higher risk for concomitant HPT with thyroid disease. Thus, routine screening for hyperparathyroidism in patients undergoing thyroid surgery, especially in vulnerable populations, such as the older and African American population, is beneficial.
