Background

Adrenal insufficiency (AI) is a life-threatening disorder caused by the deficiency of adrenal steroid hormones. This retrospective cross-sectional study investigated the characteristics of patients with AI in Korea.

Methods

All consecutive patients with suspected AI who received care at a tertiary referral center in Korea in 2014 and underwent adrenocorticotropic hormone stimulation or insulin-tolerance testing were identified through a review of medical charts. Patients diagnosed with AI were enrolled. Their demographic, clinical, and treatment details were extracted.

Results

Of 771 patients with suspected AI, 183 (23.7%) received a definitive diagnosis. The most common reason for testing was the presence of suspicious AI-related symptoms (30.0%), followed by a history of steroid medications (23.5%). Their mean age was 66.7 years, and females predominated (67.8%). The most common symptoms were general weakness, anorexia, arthralgia, and fever. Approximately half (53.6%) had a history of steroid use. Hydrocortisone was the most common treatment (71.6%), with most patients taking a 30 mg dose (44.2%). The most common dose frequency was twice a day (78.6%). Fourteen patients were treated for adrenal crisis (n=10, 5.5%) or an intercurrent illness (n=4, 2.2%).

Conclusion

AI may have been caused by steroid medication use in many of the patients included in this study. The detection of AI can be improved by careful history-taking and being alert to the possibility that a patient has used steroids.

Abstract PDF

BACKGROUND
Non-alcoholic fatty liver disease is common in patients with insulin resistance. Sterol regulatory element binding protein-1c (SREBP-1c) is a member of a family of transcription factors that have been recognized as key regulators for lipid accumulation in the liver that activate enzymes involved in the fatty acid biosynthetic pathway. This study was designed to evaluate whether alpha-lipoic acid (ALA) inhibits insulin-stimulated SREBP-1c expression. METHODS: We investigated the effects of ALA on insulin-stimulated SREBP-1c expression in a human hepatoma cell line (HepG2 cells) using Northern and Western blot analysis. We also examined the effect of ALA on the promoter activity of the SREBP-1c gene to examine whether ALA can affect SREBP-1c expression at the transcriptional level. To discern the mechanism by which ALA inhibits SREBP-1c expression, we examined the role of AMP-activated protein kinase (AMPK). RESULTS: Insulin increased the expression of SREBP-1c mRNA and protein in HepG2 cells in a dose depended manner. Co-treatment with ALA inhibited the insulin increased SREBP-1c expression in a dose-dependent manner. ALA also inhibited insulin-stimulated activation of the SREBP-1c promoter activity, indicating that ALA inhibited SREBP-1c expression at the transcriptional level. ALA increased phosphorylation of AMPK in HepG2 cells. Inhibition of the AMPK activity by compound C markedly reversed the inhibitory effects of ALA for insulin-stimulated SREBP-1c expression. These results suggest that ALA-induced suppression of SREBP-1c expression is at least in part mediated via AMPK activation. CONCLUSION: The present study suggests that ALA has an inhibitory effect on insulin-stimulated SREBP-1c expression. Therefore, further studies on the effects of ALA on hepatic steatosis in an animal model need to be performed.
