Objective To summary the clinical diagnosis and treatment of primary aldosteronism (PA) in West China Hospital (WCH) of Sichuan University during 2009-2018.
Methods This study enrolled the patients diagnosed as PA and admitted in WCH of Sichuan University from January 2009 to December 2018. The information of the patients including epidemiological and clinical data, diagnosis and treatment as well as therapeutic outcomes were collected and analyzed.
Results A total of 853 patients with 1 248 diagnostic cases were included in the analysis, and the diagnosis cases of PA increased year by year from 2009 to 2018. Most patients (74.33%) were confirmed the diagnosis in the Department of Endocrinology and Metabolism and then admitted to the hospital. PA was more frequent in female than in male, with a ratio of female to male about 1.34∶1. Hypertension was the most common chief complaint, in contrast, the proportion of fatigue and/or numbness as the symptoms of hypokalemia was declining. More and more patients were diagnosed because of imaging examination founding adrenal incidentoma. After 2016, more and more patients were diagnosed by recumbent saline suppression test and captopril challenge test, and the number of adrenal venous sampling to classify PA subtypes was increasing to help choosing different treatment options. The proportion of surgical treatment decreased year by year, and more and more patients adopted medical treatment or transferred to surgery with combined treatment instead of simple operation.
Conclusion During the past 10 years, remarkable progress was made in the diagnosis and treatment of PA. Hypertension was the most important clinical manifestation of PA, so the screening of PA in hypertensive patients should be strengthened. Adrenal incidentaloma has become prevalent manifestation of PA with an increasing trend, which needs more attention in clinical practice.
