Successful control of a case of severe insulin allergy with liraglutide.

A 72-year-old woman presented with repeated hypoglycemic and hyperglycemic episodes because of an insulin allergy. On admission, she was diagnosed with type B insulin resistance syndrome. She was also found to have anti-insulin antibodies. After steroid therapy, glycemic control improved dramatically accompanied by the disappearance of the insulin allergy. We then introduced liraglutide, which successfully stabilized her glycemic episodes without allergic reactions. Liraglutide might be useful to treat patients with severe insulin allergy.
