Prevalenza dell'iperortosilismo nei pazienti con diabete di tipo 2 difficile da controllare.

OBJECTIVE: Despite the use of multiple glucose-lowering medications, glycemic targets are not met in a significant fraction of people with type 2 diabetes. In this prospective, observational study we assessed the prevalence of hypercortisolism, a potential contributing factor to inadequate glucose control.
