Secondary hyperparathyroidism combined with thyroid disease.

Abstract

To retrospectively analyze the diagnosis and treatment of secondary hyperparathyroidism (SHPT) combined with thyroid disease, and to investigate the correlation between SHPT and papillary thyroid carcinoma (PTC), SHPT and thyroid disease, and the importance of preoperative localization diagnosis in patients with SHPT. Clinical data of 101 patients who underwent surgical treatment for SHPT at the Third Hospital of Hebei Medical University were collected from August 2014 to May 2023, and patients were divided into SHPT without PTC group (n = 94) and SHPT with PTC group (n = 7) according to their postoperative pathology. Patients were divided into SHPT without thyroid disease group (n = 32) and SHPT with thyroid disease group (n = 69) according to their preoperative ultrasound diagnosis and postoperative pathology. The differences between the 2 groups were compared to explore the association between SHPT and PTC and between SHPT and thyroid disease. Of the 101 patients with SHPT, 65 were male and 36 were female with a mean age of (44.26 ± 11.16) years. There were 69 patients (68.32%) with concomitant thyroid disease and 32 patients (31.68%) without concomitant thyroid disease, including 7 patients (6.93%) with PTC. The results of univariate analysis showed that the differences in age and preoperative PTH levels between the SHPT without PTC group and the SHPT with PTC group were statistically significant (P < 0. 05),There were no significant differences in age, gender, preoperative PTH, preoperative alkaline phosphatase, preoperative serum calcium, preoperative serum phosphorus, preoperative serum creatinine, duration of dialysis disease, and whether they were accompanied by hypertension or not between the SHPT without thyroid disease group and the SHPT with thyroid disease group (P > 0. 05), logistic regression analysis showed that there was a correlation between the age of patients with SHPT and the level of preoperative PTH with PTC. In patients with SHPT, concomitant thyroid disease is more common, so patients with SHPT should be screened for thyroid disease at the same time as routine preoperative ultrasonography combined with nuclear scan for localized diagnosis, and surgical resection is preferred if concomitant PTC is present.
