The influence of gender on clinical manifestations of primary hyperparathyroidism

To explore the impact of gender on presentation of primary hyperparathyroidism (PHPT), clinical data of 150 histopathologically proven PHPT patients were collected and retrospectively analyzed. Most of the patients (72.0%) were parathyroid adenoma (PA), and 9.3% of them were parathyroid carcinoma (PC). In PA patients, albumin-corrected serum calcium levels (TASC) were lower in women than in men [ (2.84±0.28) mmol/L vs. (3.03±0.34) mmol/L, P=0.006]. In all PHPT subjects, serum urea nitrogen, creatinine, uric acid levels were lower in women than in men. Bone pain was more frequent in women over 50 years old than in men (52.33% vs.29.17%, P=0.045). The incidence of PC was higher in men than in women (20.59% vs. 6.03%, P=0.010). In conclusion, there are gender differences in the clinical presentation of PHPT. TASC was high in men with PA compared to women with PA. Bone pain was more common in the woman patients over 50 years old, and PC was more common in men. Key words: Primary hyperparathyroidism; Sex; Clinical features
