We report 34 patients (aged 5-18 years) with acute (n = 26) or chronic (n = 1) leukemia, non-Hodgkin's lymphoma (n = 3) or severe aplastic anemia (n = 4) evaluated for pancreatic beta-cell function 9 months to 10.2 years after autologous (n = 19) or allogeneic (n = 15) BMT. Before BMT, all patients received cytotoxic drugs, combined with total body irradiation (TBI) in 24 cases or thoracoabdominal irradiation (TAI) in 4 children. Patients were investigated for fasting blood glucose (FBG), HbA1C, anti-insulin (IAA) and islet cell antibodies (ICA), first-phase insulin response (FPIR) and insulinemia/glycemia (I/G) ratio on i.v. glucose tolerance test (GTT) and C-peptide response after glucagon 1 mg i.v. Results were compared with those obtained in 21 age- and sex-matched controls. None of the patients or controls had IAA and/or ICA. FBG and HbA1C were normal in all children. In the patients, glycemia on i.v. GTT was similar to controls whereas insulin levels I/G ratio and FPIR were significantly higher in patients than in controls, as well as C-peptide levels. We divided the patients on the basis of the radiotherapy into group I with TBI (n = 18), group II with TAI (n = 4) and group III who were not irradiated (n = 4). The I/G ratio, FPIR on i.v. GTT and C-peptide response were significantly higher in group I compared with the other two groups and controls. The increased insulin and C-peptide levels in our patients with normal glycemia might be interpreted as a state of insulin resistance, more evident in patients who received TBL.

A 43-year-old Japanese man who was positive for hepatitis B surface (HBs) antigen and HB e antibody, underwent chemotherapy for non-Hodgkin's lymphoma. After the chemotherapy he suffered from acute exacerbation of hepatitis because of reactivation of HBV. Recovery was achieved with interferon-alpha, glucagon-insulin therapy, and plasma exchange. Mutations were detected in codons 97, 100, 129, and 131 of the core region of HBV. The peptide encoded from the core region including such mutations possibly had greater antigenicity to induce cytotoxic T cell activity in the host. Core region mutations may be a crucial cause of the acute exacerbation of hepatitis B seen after chemotherapy.
