<b>Pre‐clinical Cushing's syndrome: an unexpected frequent cause of poor glycaemic control in obese diabetic patients</b>

Abstract

The prevalence of pre-clinical Cushing's syndrome in obese patients with poorly controlled diabetes appears to be considerably higher than previously believed. The overnight dexamethasone suppression test proved to be a simple, sensitive and highly specific screening test for Cushing's syndrome despite the presence of obesity and hyperglycaemia.
