The aim of the study was to investigate the usefulness of metanephrine (MN) and normetanephrine (NMN) in bilateral simultaneous adrenal vein sampling (AVS) with and without ACTH stimulation. The study was conducted in a single referral center. Prospective recruited patients with PA were treated with AVS. The effects of cortisol, MN and NMN on selectivity catheterization were assessed and determined by lateralization. We enrolled 54 patients with PA who were treated with simultaneous bilateral AVS with ACTH. The Selectivity Index (SI) calculated by MN was higher than that calculated by other indicators (p<0.001), the catheterization success rate of MN at baseline was the same as that of cortisol after ACTH stimulation, and in lateralization diagnosis, MN was not inferior to cortisol. In conclusion, among the studied indicators, MN is the best index for determining the catheterization selectivity in AVS, especially in the absence of ACTH stimulation. [ABSTRACT FROM AUTHOR]

The aim of the study was to investigate the significance and influence of adrenocorticotropic hormone (ACTH) stimulation in primary aldosteronism (PA) patients with simultaneous bilateral adrenal vein sampling (AVS). All patients diagnosed with PA underwent simultaneous bilateral AVS with ACTH. In 95 patients, the post-ACTH SI significantly increased (p<0.001), and it gradually decreased from t10–t30 after ACTH stimulation (p<0.001). The unsuccessful catheterization decreased after ACTH stimulation. Time points within 20 min after ACTH stimulation were better for sampling, and the selectivity did not increase over longer periods. According to lateralization before and after ACTH stimulation, the patients could be divided into 3 groups (U, unilateral; B, bilateral): U/U , U/B or B/U, and B/B. Compared with the U/U group, in the U/B or B/U and B/B groups, the lateralization index (LI) was lower both at baseline and after ACTH stimulation (p<0.0001), the contralateral index (CLI) was higher after ACTH stimulation (p<0.003), the serum potassium level was higher (p<0.001), and the carbon dioxide combining power (CO2CP) and base excess (BE) levels were lower. In conclusion, in simultaneous bilateral AVS, ACTH stimulation had significant effects on increasing the catheterization selectivity. Lateralization change was observed after stimulation. After ACTH stimulation, fewer patients could be diagnosed with lateralized PA. Patients with consistent lateralized PA showed a more serious phenotype. [ABSTRACT FROM AUTHOR]

Aim: To compare the blood glucose control of patients with type 2 diabetes mellitus (T2DM) with different treatment methods, oral hypoglycemic agents (OHA) monotherapy, insulin injection and combined therapy (OHA + insulin injection) and evaluate their satisfaction with the medical care. Methods: A total of 1512 T2DM patients were assessed, to compare the effects of different treatment methods on glycemic control in T2DM patients, the influencing factors of patients' satisfaction with medical care measures and their relationship with glycemic control. Fasting plasma glucose (FPG), 2 hrs postprandial plasma glucose (2hPG) and HbA1c were measured as the standard of the glycemic control. Satisfaction was defined using the simplified version of DAWN of chronic disease care patient scale (PACIC - DSF). Results: In this study, the FPG compliance rate, 2hPG compliance rate and HbA1c compliance rate were 25.5%, 22.7% and 19.5%, respectively. The differences in the glycemic control compliance rates of different treatment methods were not statistically significant. The total score of PACIC - DSF was 34.54±11.65(p>0.05), and the influencing factors included fast blood glucose (FBG) and 2hPG, 2hPG and PACIC - DSF were negatively correlated. Conclusions: The T2DM glycemic control rate in China is currently low. From the score of the PACIC - DSF, there is no significant difference in general satisfaction with medical care measures in different treatments. What is more, education level, occupation and exercise of patients with type 2 diabetes had influence on PACIC - DSF score. Different treatment methods have no influence on the glycemic control of patients with T2DM. FPG value and the 2hPG value are negative correlation with the satisfaction of patients in medical care measures. [ABSTRACT FROM AUTHOR]
