A 29-year-old woman was admitted to our hospital for treatment of fulminant type 1 diabetes (FT1D) with diabetic ketoacidosis. The phenotype of peripheral blood lymphocytes was analyzed using an 8-color flow cytometer. An analysis of the CD4-positive T cells showed a tendency for higher proportions of effector and central memory T cells and a normal proportion of regulatory T (Treg) cells, compared to healthy control. An analysis of B cell differentiation showed higher proportions of switched memory B cells and plasmablasts. The differences in lymphocyte phenotypes between our case and previously reported cases suggest a diversity of FT1D pathology.
