We encountered a 68-year-old woman with type 2 diabetes who had frequent insulin-induced hypoglycemia in the morning. She had renal failure, and was on hemodialysis. The hypoglycemia in the morning was severe, induced by the small dosage of insulin, whilst she showed severe postprandial hyperglycemia. A blood test revealed high serum insulin and C-peptide levels, and a high binding rate of insulin antibody. Switching human insulin to an insulin analogue, glulisine, failed to avoid hypoglycemia. Scatchard plot analysis indicated that the high affinity site of the patient’s insulin antibody had a low affinity constant (K1) and a high binding capacity (R1) against all tested insulin, almost equivalent values reported in insulin autoimmune syndrome cases. Treatment with the glucagon-like peptide-1 analogue liraglutide ameliorated the postprandial hyperglycemia without hypoglycemia, resulting in improved glycemic stability. Furthermore, the continued use of liraglutide reduced both serum insulin level and binding rate of insulin antibody. This is the first case of using liraglutide in an insulin-antibody positive patient with renal failure on hemodialysis. Liraglutide could be an effective and safe remedy for patients with insulin antibody-related glucose instability, regardless of their renal function.
