AI Article Synopsis

  • Cushing syndrome (CS) is a condition characterized by high cortisol levels that lead to various metabolic issues, including increased abdominal fat and diabetes, while zinc alpha-2 glycoprotein (ZAG) is an adipokine that helps regulate fat metabolism.
  • An observational study involving 39 women (13 with active CS and 26 controls) measured plasma ZAG levels to understand its relationship with hypercortisolism and other metabolic factors.
  • Results indicated that ZAG levels were significantly higher in CS patients, positively correlating with factors like urinary cortisol, BMI, glucose, and type 2 diabetes, suggesting ZAG's potential role in fat distribution changes associated with high cortisol levels.

Article Abstract

Introduction: Cushing syndrome (CS), an endogenous hypercortisolemic condition with increased cardiometabolic morbidity, leads to development of abdominal obesity, insulin resistance, diabetes and proatherogenic dyslipidemia. Zinc alpha-2 glycoprotein (ZAG) is a recently characterized lipolytic adipokine implicated in regulation of adipose tissue metabolism and fat distribution. In vitro and animal studies suggest that glucocorticoids interact with ZAG secretion and action. To assess the relationship between ZAG and glucocorticoids in a human model of hypercortisolism, circulating ZAG levels were tested in patients with CS and its counterpart controls.

Methods: An observational, cross-sectional study on 39 women, 13 with active CS and 26 controls matched by age and body mass index. Plasma ZAG levels (μg/ml) were measured by ELISA and correlated with hypercortisolism, metabolic, and phenotypic parameters.

Results: Plasma ZAG levels were significantly higher in patients with CS compared to controls (64.3±16.6 vs. 44.0±16.1, p=0.002). In a univariate analysis, ZAG levels positively correlated to 24-h urinary free cortisol (p=0.001), body mass index (p=0.02), non-esterified fatty acids (p=0.05), glucose (p=0.003), LDL-C (p=0.028), and type 2 diabetes mellitus (p=0.016), and were inversely related to total adiponectin levels (p=0.035). In a multivariate analysis, after adjusting for CS, ZAG levels only correlated with body mass index (p=0.012), type 2 diabetes mellitus (p=0.004), and glucose (p<0.001).

Conclusion: This study provides initial evidence that plasma ZAG levels are higher in patients with CS as compared to controls. The close relationship of ZAG with metabolic and phenotypic changes in CS suggests that ZAG may play a significant role in adipose tissue changes in hypercortisolism.
