Brief Summary:
In obese individuals cortisol production and secretion is increased but the underlying mechanism is not known. Obesity leads to a pathological activation of the innate immune system partly driven by tissue production of IL-1β. Furthermore, IL-1β is also known to stimulate the release of adrenocorticotropin hormone (ACTH). Therefore, the investigators hypothesise that in obese individuals tissue inflammation stimulates ACTH via IL-1β, thereby explaining the observed hypercortisolism.

Primary Outcome Measures :
  1. Morning cortisol levels [ Time Frame: 14 days ]

Secondary Outcome Measures :
  1. effect of anakinra/Kineret® on salivary cortisol, free urinary cortisol, and serum cortisol levels after an overnight dexamethasone suppression test [ Time Frame: 14 days ]
  2. correlation between the percentage of body fat or body mass index, and suppression of cortisol levels after injection of anakinra/Kineret® [ Time Frame: 14 days ]
  3. correlation between inflammatory parameters with cortisol levels [ Time Frame: 14 days ]
  4. impact of anakinra/Kineret® on other pituitary and peripheral hormones, such as: ACTH, TSH, fT4, GH, IGF-1, LH, FSH, testosterone copeptin, IL-6, CRP, leukocyte count and body temperature. [ Time Frame: 14 days ]
    impact of anakinra/Kineret® on other pituitary and peripheral hormones such as: ACTH, thyroid-stimulating Hormone (TSH), free thyroxine 4 (fT4), growth Hormone (GH), insulin like growth factor (IGF)-1, luteinizing Hormone (LH), follicle stimulating Hormone (FSH), testosterone copeptin, interleukin (IL)-6, C reactive protein (CRP), leukocyte count and body temperature.

  5. comparison of 1mg and 2mg dexamethasone suppression test [ Time Frame: 4 weeks ]
