Dead-in-bed syndrome unexpected death in young type 1 diabetic patients "with no history of diabetic complications, and in particular no autonomic dysfunction. They are found in an undisturbed bed, which seems to exclude death during a convulsive attack"[1].
This was first described in a series of 20 patients in 1991[2].
Etiology
Proposed causes include:
- Hypoglycemic unawareness[3][4] or the 'hypoglycemia-unawareness syndrome'[5]
- Hypoglycemia-induced ventricular dysrhythmia due to QT prolongation during hypoglycemia[6][7]
- Hypoglycemia-induced autonomic dysfunction which may lead to ventricular dysrhythmia due to QT prolongation[8]
Diagnosis
Diabetic ketoacidosis may be sought during autopsy by vitreous fluid biochemical analyses [9].
Prevention
Nocturnal hypoglycemia may be prevented by glucose sensors[10][11][12]; however, this may not completely prevent dead in bed syndrome[13]
