HLA phenotype and insulin antibody production.
HLA phenotypes have been determined in 79 patients as part of a prospective study of factors governing the immune response to injected insulin. IgG insulin antibody levels 6 months after starting treatment with bovine insulin were significantly higher in patients bearing HLA-DR7 and this in conjunction with the lack of a similar pattern in the IgG response to Helix pomatia haemocyanin, suggests the presence of an immune response gene for insulin. The hyporesponsiveness of HLA-B8/DR3/C4AQ0 positive individuals is more likely to reflect a non-specific abnormality of immunity.
