Abstract
BACKGROUND
Intraoperative parathyroid hormones have been used to establish operative success in patients with primary hyperparathyroidism. This study's aim was to assess the impact of estimated glomerular filtration rate and serum creatinine levels on the fulfillment of >50% drop and normalization of intraoperative parathyroid hormone levels.
METHODS
Patients successfully treated for primary hyperparathyroidism were analyzed. The samples for parathyroid hormone were collected at baseline, 5-, 10-, and 30-minutes postexcision. The patients were classified as follows: (1) estimated glomerular filtration rate >60 mL/min, (2) estimated glomerular filtration rate <60 mL/min and serum creatinine levels <1.2 mg/dL, and (3) estimated glomerular filtration rate <60 mL/min and serum creatinine levels >1.2 mg/dL. Comparative analysis of patients achieving the >50% parathyroid hormone drop criterion and normalization of intraoperative parathyroid hormone was performed.
RESULTS
One hundred-fourteen patients were distributed as follows: 88 patients (77.2%), 14 (12.3%), and 12 (10.5%) for groups 1, 2 and 3, respectively. No difference between groups in the proportion of patients fulfilling the >50% parathyroid hormone drop criterion was found. An abnormally elevated intraoperative parathyroid hormone level at 30-minute postexcision was observed in 0, 14.3, and 16.6% in groups 1, 2, and 3, respectively (P ≤ .0001).
CONCLUSION
In the study, >50% parathyroid hormone drop criterion was equally achieved despite normal or reduced estimated glomerular filtration rate. When serum creatinine levels increased >1.2 mg/dL and estimated glomerular filtration rate declined <60 mL/min, the likelihood of reaching normal intraoperative parathyroid hormone levels postexcision was significantly lower.
