Clinical characteristics of the patients with asymptomatic primary hyperparathyroidism / 中南大学学报(医学版)

OBJECTIVES@#The prevalence of asymptomatic primary hyperparathyroidism (PHPT) in China is lower than that in European and American countries and the study about the characteristics of asymptomatic PHPT was rare in China. This study aims to explore the characteristics of asymptomatic PHPT.@*METHODS@#Clinical data of 150 patients with PHPT confirmed by operation and pathological examination were retrospectively analyzed. The patients were assigned into a symptomatic PHPT group (@*RESULTS@#The proportion of adenomas was higher than that of adenocarcinoma in the asymptomatic PHPT group. The proportion of the first diagnosis due to hypercalcemia found via biochemical examination in the asymptomatic PHPT group was higher than that in the symptomatic PHPT group (76.92% vs 25.81%, @*CONCLUSIONS@#Only a minority of PHPT patients are asymptomatic. Compared with the symptomatic PHPT patients, the primary cause of diagnosis is hypercalcemia, the duration of diagnosis and the diameter of parathyroid gland are shorter, the levels of serum calcium, and PTH are lower, the proportion of adenomas, vitamin D, and the BMD of L

The analysis of clinical features of 140 cases with primary hyperparathyroidism / 中国肿瘤临床

Objective:To compare the clinical characteristics in primary hyper(-) parathyroid hormone (PHPT) of the different patholog-ic types. Methods:Clinical data of 140 patients with PHPT proved by operation and pathology during January 2010 to June 2016 were retrospectively analyzed. Results:A total of 140 PHPT patients, including 13 (9.29%) cases of parathyroid carcinoma (PC), 27 (19.29%) cases of parathyroid hyperplasia (PH), and 100 (71.43%) cases of parathyroid adenoma (PA). The duration of the PC group was longer than the PH group and the duration of the parathyroid adenoma (PH) group was longer than the PA group (P0.05). The postoperative calcium level of PC group was lowest (P<0.001), and the highest was of PTH (P<0.001). The pro-portions of clinical manifestation of the urinary system, digestive system, and nervous system in the PC group were 76.92%(10/13), 76.92%(10/13), and 15.38%(2/13), respectively, and these values were the highest in the three groups (P<0.05). The proportion of the clinical manifestation of the urinary system of the PH group was higher than that of the PA group. The fracture rate (30.77%, 4/13) and constipation rate (38.46%, 5/13) of the PC group were the highest among the three groups (P<0.05). Conclusion:The duration of patients with PC was the longest among the three groups. The percentage of young patients with PC was the highest. The abnormal parathyroid glands in the PC group were the heaviest. The PC group exhibited the lowest postoperative calcium level and the highest PTH level. The biochemistry and clinical manifestations of PC were obvious.
