Somogyi effect as the most common cause of fasting hyperglycemia in T1D patients
نویسندگان
چکیده
Materials and methods We analyzed the glycemic profile measured by 72h-CGMS in 85 patients with T1D (29 female), resulting in 255 overnight periods. We assessed the nocturnal glycemic profile and the accuracy of the CGMS sensor per night. Fasting hyperglycemia was categorized into dawn phenomenon when there was no nocturnal hypoglycemia followed by a minimum 10mg/dL rise plasma between 4: 00h-7: 00h; Somogyi effect when nocturnal hypoglycemia (< 70mg/dL) between 0: 00h-3: 00h was followed by morning hyperglycemia and poor glycemic control when there was sustained overnight hyperglycemia. Clinical data (age, diabetes duration, insulin regime, and HbA1c values) were obtained by chart review and compared to the different causes of fasting hyperglycemia.
