Initiation of Biphasic Insulin Aspart in a Patient Failing Basal Insulin Treatment
This case illustrates insulin intensification from insulin glargine to biphasic insulin aspart 30 (BIAsp 30), reviews supporting clinical literature and discusses alternative therapeutic approaches. PL, a 56-year-old male with an eight-year history of type 2 diabetes, needed to intensify his insulin glargine treatment as he was not achieving appropriate blood glucose targets and recurrent hypoglycaemia limited further dose titration. With insulin glargine, his glycosylated haemoglobin (HbA1c) was 7.8 %, his fasting plasma glucose (FPG) ranged from 7.2 mmol/l to 8.0 mmol/l and his postprandial glucose (PPG) ranged from 8.9 mmol/l to 10.6 mmol/l, being especially high after dinner. At four months after the switch to BIAsp 30, his HbA1cwas 6.9 % and his FPG and PPG levels were at goal. The patient had not experienced any hypoglycaemic episodes. By addressing both PPG and FPG, intensification with BIAsp 30 provided improved glycaemic control without the hypoglycaemia experienced with insulin glargine.
