    Abstract:
    A double-blind comparative trial of the effectiveness and antigenicity of semisynthetic human insulin (Novo) and highly purified (Monocomponent) porcine insulin was performed over a 12 month period in 20 diabetic subjects newly treated with insulin. Human insulin was shown to be indistinguishable from porcine insulin of comparable purity with respect to plasma glucose and glycosylated hemoglobin levels and insulin dose requirements. Human insulin was no less antigenic than porcine insulin; significant IgG-associated insulin binding activity was detected in six of the ten patients in the human insulin treated group and four of the ten patients in the porcine insulin treated group. In all patients, the binding activity was of low capacity. No adverse reactions to human insulin were noted. It is concluded that semisynthetic human insulin, like purified porcine insulin, is safe and effective. Although there may be advantages for human insulin in the setting of insulin allergy, this study does not indicate that human insulin has advantages over purified porcine insulin with respect to elicitation of antibodies of the IgG class.
