摘要: Significant early-morning hyperglycemia was observed in insulin-dependent diabetic individuals who were otherwise well controlled while receiving a continuous subcutaneous insulin infusion (CSII) at standard doses. We measured the levels of five key counterregulatory hormones (CRH) throughout night for total 10 patient-nights four such patients. No abnormalities patterns glucagon, cortisol, growth hormone, epinephrine, or norepinephrine secretion observed. Stepping up daytime basal infusionrate six affected patients before bedtime by 37.0 ± 7.5% and maintaining increased until breakfast significantly blunted this without causing significant early nighttime hypoglycemia. Plasma glucose concentrations averaged 106.8 13.0 mg/dl after increase overnight rate as compared with 269.8 39.1 single over 24 h ( P
