✦ Synopsis

Hypoglycaemic episodes and low insulin requirements are frequently seen in the early phase of treatment of Type 1 diabetes mellitus but the mechanism is not clear. We present a diabetic patient with recurrent hypoglycaemia in the early phase of insulin treatment. A very high glucose transport in adipocytes (basal: 176 and insulin stimulated glucose transport 10 -7 mol l -1 : 335 fl cell -1 s -1 ) was found when compared with reference laboratory diabetic patients (basal: 59 ؎ 10 and insulin 10 -7 mol l -1 : 106 ؎ 7 fl cell -1 s -1 , mean ؎ SE) and with reference laboratory of non-diabetic subjects (basal: 106 ؎ 6 and insulin 10 -7 mol l -1 : 188 ؎ 15 fl cell -1 s -1 ). Insulin binding to adipocytes was in the normal range. The patient was studied again 1 year later when the partial clinical remission had disappeared, and the glucose transport in adipocytes had decreased. In conclusion, an increase in glucose uptake by peripheral tissues may be among the mechanisms of the partial 'honeymoon' period of diabetic patients.
