Immunogenicity of "single component" port insulin.
Twelve diabetic subjects who were not previously treated with insulin were divided into two groups of six each. Group I was treated with single component pork insulin and Group II was treated with standard (USP) insulin for 5 to 10 months. Three out of six in Group I, and five in Group II, developed circulating insulin antibodies. Daily insulin requirement in the two groups were almost the same. Insulin antibody titer did not fall in three insulin-treated diabetic subjects when single component pork insulin was substituted for USP beef-pork insulin. This study shows that the single component insulin is antigenic in human subjects.
