Evaluation of the hypothalamo-pituitary-adrenal axis using the cortisol awakening response test in patients with type 1 diabetes mellitus with and without depression: Multicenter Argentine Study (EMA-1)

Abstract

Introduction: depression (DP) has a high prevalence in patients with type 1 diabetes mellitus (DM1) and is associated with negative clinicals consequences like more cardiovascular morbimortality and chronic complications. There are few studies published about the dysregulation of hypothalamo-pituitary-adrenal axis (H-P-A) in DM1 with DP and the relation between DP and the Cortisol Awakening Response Test (CAR) with the glycemic control (GC). Objectives: examine the functionality of the H-P-A axis using the Cortisol Awakening Response Test (CAR), in patients with DM1 (PD1) with and without DP. Determine the prevalence of DP in PD1 and examine if there is any relation between CAR and GC and DP and poorer GC. Materials and methods: observational, prospective, national, multicenter study. Patients with DM1, older than 18 years old; Patient Health-9 questionnaire (PHQ-9) was used to diagnose DP and 2 samples of salivary cortisol, and blood samples for glycemia, glycated albumin and Hba1c.
