Abrupt onset of type 1 diabetes mellitus during recombinant interferon-alpha 2b therapy in a patient with chronic hepatitis B

摘要： We describe a case of a 33-year-old female patient with chronic hepatitis B who developed type 1 diabetes mellitus (DM) after a 13-mo period of treatment with recombinant human interferon-alpha (IFN-α) 2b. The patient presented with polydipsia, polyuria, hypergly-cemia, diabetic ketoacidosis, combined with C-peptide secretion defi ciency and positive islet cell autoantibody (ICAb). IFN-α 2b treatment was terminated and in-stead insulin treatment was initiated. Five months after cessation of the recombinant human IFN-α 2b therapy, the patient remained insulin-dependent. Her serum HBV DNA became negative and serum transaminase returned to the normal level after a 10-mo period of IFN therapy. Type 1 DM induced by IFN-α is relatively rare in patients with chronic hepatitis B. We should pay more attention to patients on IFN-α therapy to avoid destruction of pancreatic beta cells. This is the first case report from China. ... （共3頁）
