Investigations showed marked hyperinsulinemia, positive insulin antibodies with low affinity/high binding capacity, insulin-specific IgE and eosinophil infiltration on skin biopsy, confirming insulin allergy. Positivity for insulin receptor autoantibodies (IRAb) initially led to a diagnosis of type B insulin resistance syndrome. However, a relatively low C-peptide level (1.57 ng/mL) despite severe hyperinsulinemia (1231.9 μU/mL) was key for differentiation. After cessation of insulin and initiating a multi-drug anti-diabetes regimen, the patient's glycemic control improved markedly, with a decrease in HbA<sub>1c</sub> from 12.3 to 6.7%. His serum insulin level decreased, and his IRAb test turned negative. This case highlights the fact that a high insulin antibody titer can cause a false-positive IRAb result. A disproportionately low C-peptide level in the presence of hyperinsulinemia may aid differentiation between insulin allergy and type B insulin resistance syndrome.</p>","PeriodicalId":51250,"journal":{"name":"Journal of Diabetes Investigation","volume":"17 3","pages":"546-548"},"PeriodicalIF":3.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12950914/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146027906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
