- Abstract
Objective: To compare the diagnostic value of adrenocorticotropic hormone (ACTH) stimulation test (AST) with different doses of ACTH combined with midnight administration of 1 mg dexamethasone for the determination of the subtypes of primary hyperaldosteronism (PA)., Methods: This is a prospective observational study. Patients diagnosed with PA in the Department of Endocrinology, the First Medical Center of of Chinese PLA General Hospital from January 1, 2020 to September 30, 2022 underwent AST with different doses of ACTH. All patients received 1 mg dexamethasone at midnight for inhibition. Then, the patients were randomly assigned to 25-unit and 50-unit ACTH treatment groups by a ratio of 1:2. Subtype classification and diagnosis of aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA) was made on the basis of adrenal venous blood samples and/or postoperative pathology and clinical follow-up findings. Receiver operating characteristics (ROC) curves were plotted to examine the diagnostic efficacy and the difference of AST by varying doses of ACTH in distinguishing APA and IHA., Results: A total of 82 patients, including 49 patients with APA (59.8%) and 33 patients with IHA (40.2%), were enrolled. There were 29 patients in the 25-unit ACTH group (35.4%) and 53 patients in the 50-unit ACTH group (64.6%). There were no significant differences in age, sex, blood pressure, minimum serum potassium, and biochemical parameters between the 25-unit and 50-unit groups. After ACTH stimulation, plasma aldosterone concentration (PAC), cortisol (F), and PAC/F at different points of time showed no statistical difference between the two groups ( P >0.05). The area under the curve ( AUC ) of PAC in the 25-unit group was higher than that of PAC/F. The AUC of PAC reached the maximum at 90 minutes (0.948, 95% confidence interval [ CI ]: 0870-1.000) and the optimal cutoff was 38.0 ng/dL, which had a sensitivity of 92.9% and a specificity of 86.7% for differentiating APA and IHA. Similar to the 25-unit group, the maximum AUC of PAC in the 50-unit group was greater than that of PAC/F. The AUC of PAC reached the maximum 90 minutes (0.930, 95% CI : 0.840-0.994) and the optimal cutoff was 39.6 ng/dL, which had a sensitivity of 91.2% and a specificity of 83.3%. The AUC of PAC at different points of time in the 25-unit ACTH group (0.862-0.948) was greater than that of 50-unit ACTH group (0.823-0.930), but the difference was not statistical significance., Conclusion: AST with 25-unit or 50-unit ACTH combined with small-dose dexamethasone can be used in PA subtype determination, ie, differentiation between APA and IHA. The optimal PAC cut-off values for 25-unit or 50-unit ACTH are similar, being 38.0 ng/dL and 39.6 ng/dL, respectively, and both cutoff values show higher sensitivity and specificity at 90 min. The AST with 25-unit ACTH has the smaller dose and the better safety. Therefore, it is recommended for the diagnosis of PA subtypes., Competing Interests: 利益冲突 所有作者均声明不存在利益冲突, (© 2024《四川大学学报(医学版)》编辑部 版权所有Copyright ©2024 Editorial Board of Journal of Sichuan University (Medical Sciences).)

- Abstract
Objective: To investigate the influence of hemoglobin glycation index (HGI) on the risk of incident chronic kidney disease (CDK) among nondiabetic patients. Methods: Prospective cohort study. At baseline, a total of 7 407 nondiabetic patients without a history of CKD from Pingguoyuan Community of the Shijingshan District in Beijing were included from December 2011 to August 2012, who were then divided into three groups according to the tertiles of their baseline HGI levels. The CKD incidence rate was compared among the different HGI groups at last follow-up. Cox multivariable regression was applied to evaluate whether HGI measures predicted CKD risk. Test for trend across tertiles were examined using ordinal values in separate models. Results: The mean age of the subjects was (56.4±7.5) years, and 4 933 (66.6%) were female. At mean follow-up of 3.23 years, 107 (1.4%) individuals developed CKD. The incidence of CKD was gradually increasing from the low to high HGI groups [1.1% (28/2 473) vs. 1.2% (31/2 564) vs. 2.0% (48/2 370), P =0.016]. In the multivariate Cox regression analysis, after adjustment for potential confounders, the high HGI group had a 68.5% increased risk of CKD compared with the low HGI group ( HR =1.685, 95% CI 1.023 to 2.774). CKD risk increased with increasing HGI tertiles ( P for trend=0.028). Conclusion: High HGI is associated with an increased risk for CKD in the nondiabetic population, indicating that HGI may help identify individuals at high risk for CKD.

- Abstract
Objective: To explore the value of serum parathyroid hormone (PTH) in the diagnosis of primary aldosteronism (PA) and to investigate an optimal cut-off of serum PTH to distinguish PA from nonfunctional adrenal tumor (NFA). Methods: The clinical data of patients with adrenal incidentaloma in Chinese PLA General Hospital from January 1, 2017 to December 31, 2019 were collected. The data of PA and NFA by clinical characteristics and evaluation on endocrine function were retrospectively analyzed. The logistic regression model was used to find the potential risk factors of elevated PTH. The receiver operating characteristic(ROC) curve was used to evaluate the efficacy of PTH in diagnosis of PA and to explore the best cut-off value. Results: A total of 773 patients were included. There were 356 PA patients (203 males, 57.0%), aged (50±11) years and 417 NFA patients (219 males, 52.5%), aged (51±12) years. The serum PTH level in patients with PA was significantly higher than that in patients with NFA [63.1 (48.4, 80.3) ng/L vs 41.7 (34.1, 51.7) ng/L, P <0.05], as well as the proportion of patients with elevated PTH level (47.8% vs 7.2%, P <0.05). Logistic regression analysis showed that having PA and deficiency of Vitamin D were risk factors for PTH elevation (both P <0.05). The ROC curve showed that the best cut-off value of PTH for the diagnosis of PA in patients with vitamin D deficiency was 56.44 ng/L, with a sensitivity of 66.5% and a specificity of 83.0%, and that in patients with normal vitamin D was 48.81 ng/L, with a sensitivity of 70.5% and a specificity of 72.6%. Conclusions: Patients with PA tend to show increased levels of serum PTH compared with NFA patients. The level of serum PTH can be used as one of the valuable indexes in screening of PA.
