Background
Parathyroid glands consist of chief cells and oxyphil cells. The parathyroid oxyphil cell proportion increased dramatically in patients with chronic kidney disease (CKD). The importance of the oxyphil cell in the treatment of secondary hyperparathyroidism (SHPT) has been enhanced in recent years. The aim of this study was to explore the possible relationship between parathyroid oxyphil cell proportion and clinical features of patients with CKD.
Methods
From December 2010 to December 2018, 78 consecutive patients with CKD 5 who underwent parathyroidectomy (PTX) were reviewed. None of the patients had used Cinacalcet. Patients were divided into two groups according to their parathyroid oxyphil cell proportion. The mean parathyroid oxyphil cell proportion of all the patients was obtained. Group 1 consisted of 37 patients, the parathyroid oxyphil cell proportion of whom was more than or equal to mean proportion. Group 2 consisted of 41 patients, the parathyroid oxyphil cell proportion of whom was less than mean proportion. The demographic and biochemical data of the two groups were compared.
Results
Preoperative parathyroid hormone (PTH) and total weight of removed parathyroid glands in the patients of group 1were less than those in group 2. There was no difference between the two groups in terms of preoperative calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), age and dialysis years.
Conclusion
The parathyroid oxyphil cell proportion was associated with preoperative PTH and total weight of removed parathyroid glands in the patients with CKD. Patients with more parathyroid oxyphil proportion had lower preoperative PTH level and smaller total weight of the removed parathyroid glands.
