Parathyroidectomy markedly reduces oxidative stress in a patient with primary hyperparathyroidism

Parathyroidectomy for hyperparathyroidism has been associated with a survival benefit, but the mechanisms remain unclear. We are reporting on an 88-year-old female patient who had high serum calcium and intact parathyroid hormone levels associated with an enlarged parathyroid gland. A parathyroidectomy was performed due to a diagnosis of primary hyperparathyroidism. After the surgery, there was a marked decrease in the oxidative stress markers, such as the ratios of oxidized to unoxidized albumin and advanced oxidation protein products. These results suggest that parathyroidectomy reduces oxidative stress in patients with primary hyperparathyroidism, which may in part explain the reduced risk for cardiovascular and all-cause mortality after parathyroidectomy.
