The use of non-insulin anti-diabetic agents to improve glycemia without hypoglycemia in the hospital setting: focus on incretins

Abstract

Patients with hyperglycemia in hospital have increased adverse outcomes compared with patients with normoglycemia, and the pathophysiological causes seem relatively well understood. Thus, a rationale for excellent glycemic control exists. Benefits of control with intensive insulin regimes are highly likely based on multiple published studies. However, hypoglycemia frequency increases and adverse outcomes of hypoglycemia accrue. This has resulted in a 'push' for therapeutic nihilism, accepting higher glycemic levels to avoid hypoglycemia. One would ideally prefer to optimize glycemia, treating hyperglycemia while minimizing or avoiding hypoglycemia. Thus, one would welcome therapies and processes of care to optimize this benefit/ risk ratio. We review the logic and early studies that suggest that incretin therapy use in-hospital can achieve this ideal. We strongly urge randomized prospective controlled studies to test our proposal and we offer a process of care to facilitate this research and their use in our hospitalized patients.
