A clinical analysis of 123 cases of primary empty sella / 中华内科杂志

Objective This study was conducted to analyze the clinical characteristics and pituitary function of patients with primary empty sella (PES).Methods The clinical data from 123 hospitalized adult patients with PES from January 2010 to May 2016 were retrospectively studied.Results (1) The average age of the 123 (male 43,female 80) PES patients was (59.2 ± 13.6) years (ranging 24-92 years),among whom 61％ patients were in the age group between 50-69 years.(2) The symptoms of the patients included fatigue (56.1％),headache (34.1％),nausea and vomiting (17.9％),gonadal dysfunction (17.1％),visual disturbance (5.7％) and hypopituitarism crisis (3.3％).(3) Hypopituitarism was found in 66 of the 123 patients.Among them,36.6％,31.7％ and 17.1％ were central hypoadrenalism,hypogonadism,and hypothyroidism,respectively.The percentage of hypopituitarism in complete PES was significantly higher than that in partial PES (P ＜ 0.05).(4) Sixteen patients were concomitant with other autoimmune diseases including 11 patients with Graves' disease and 2 with Cushing's syndrome due to adrenal adenoma.Conclusions The incidence of hypopituitarism in PES was 53.7％,in which the pituitary-adrenal axis hypofunction was more common.An overall evaluation of the pituitary function was essential for the patients who had headache and fatigue,or with suspected PES.The patients with hypopituitarism should be given hormone replacement therapy in time and followed up afterword.
