Abstract:
Context. Previous data suggest a possible association between type 2 diabetes (T2D) and fragility fractures (FX) with the degree of glucocorticoid suppressibility (GCS) and peripheral activation or sensitivity even in non-hypercortisolemic subjects.
Objective. To investigate if in subjects without overt or mild hypercortisolism the degree of GCS, GC sensitivity and peripheral activation are associated with hypertension (Hy) and with the number of the possible consequences of cortisol excess among T2D, fragility FX and Hy.
Design. Case-control study Setting. Outpatient basis Patients. 216 non-hypercortisolemic postmenopausal females (age 50-80 years, 108 with Hy); 68 and 99 patients had fragility FX and T2D, respectively Main outcome measures. We assessed 24-hour urinary free cortisol (UFF), cortisone (UFE), their ratio (R-UFF/UFE), cortisol after 1mg-overnight-dexamethasone (F-1mgDST), and the GC receptor N363S single-nucleotide polymorphism (N363S-SNP).
Results. Hy was associated with F-1 mgDST (odds ratio, OR, 3.3, 95% confidence interval, 95%CI, 1.5-7.5, p=0.004) and R-UFF/UFE (OR 101.7, 95%CI 2.6-4004.1, p=0.014), regardless of age, BMI and presence of the N363S-SNP and of T2D. The progressive increase of the number of the possible consequences of cortisol excess was significantly associated with F-1mgDST levels (R2=0.125, p=0.04), with R-UFF/UFE (R2 =0.46, p=0.02) and with the prevalence of N363S heterozygous variant (T=0.46, p=0.015), after adjusting for age.
Conclusions. In postmenopausal non-hypercortisolemic females Hy is associated with GCS and GC peripheral activation. The number of the possible consequences of cortisol excess (among Hy, T2D and fragility FX) are associated with GCS, GC peripheral activation and with the prevalence of N363S heterozygous variant.
