Blood glucose control on Sunday in IDDM patients: intensified conventional insulin therapy versus continuous subcutaneous insulin infusion

Abstract We have assessed the capacity of continuous subcutaneous insulin infusion (CSII) to maintain good blood glucose metabolic control on Sundays, when waking is delayed, with reference to intensified conventional insulin therapy by multiple daily injections (MDI). The study lasted 3 weeks, including 3 week-ends. A total of 20 IDDM patients were selected for metabolic control: ten were treated by CSII and ten by MDI. Blood glucose was determined at least three times a day (fasting on waking, pre-lunch and pre-dinner). The times of blood glucose determinations and their values were recorded in a memory reflectance meter. Waking, the first blood glucose measurement and the first insulin injection (MDI) or bolus (CSII) were about 1 h later on Sundays than on a weekday (44±4 min in MDI group, P P P
