OBJECTIVE To describe the clinical and immunologic characteristics of fulminant type 1 diabetes, a novel subtype of type 1 diabetes, we conducted a nationwide survey. RESEARCH DESIGN AND METHODS History and laboratory data, including islet-related autoantibodies, were examined in 222 patients with fulminant and nonfulminant type 1 diabetes in our(More)
We have shown previously that alloxan and streptozotocin, two major diabetogenic agents, cause DNA strand breaks in rat pancreatic islets and stimulate nuclear poly(ADP-ribose) synthetase, thereby depleting intracellular NAD level and inhibiting proinsulin synthesis (Okamoto, H. (1981) Mol. Cell. Biochem. 37, 43-61; Yamamoto, H., Uchigata, Y., and Okamoto,(More)
To assess the effect of Asian-specific HLA haplotypes on susceptibility to type 1 diabetes, we investigated the association of genotypic combinations of DRB1-DQB1 haplotypes with susceptibility to type 1 diabetes. We studied 132 Japanese patients with type 1 diabetes and 157 control subjects, along with 67 Korean patients and 109 control subjects.(More)
Nicotinamide (10 mmol/kg) and 3-aminobenzamide (1.25 mmol/kg), poly(ADP-ribose) synthetase inhibitors, were injected intravenously to rats either 30 min before the intravenous administration of 12 mg/kg alloxan or 50 mg/kg streptozotocin ("pretreatment") or 5 min after the administration ("posttreatment"). Fifteen minutes after the injection of the(More)
BACKGROUND Whether the type of diabetes, race, and year and age of diagnosis affect the incidence of diabetic vascular complications is unknown. That both type 1 and type 2 diabetes occur in the young Japanese population prompted us to investigate whether the type of diabetes and the year of diagnosis are related to the incidence of nephropathy.

Fulminant type 1 diabetes, which is characterised by a markedly acute onset of diabetes and an absence of islet-related autoantibodies, accounts for 20% of type 1 diabetes in Japan. We aimed to clarify the contribution of the HLA subtype to fulminant type 1 diabetes in Japanese. We determined the serological subtypes of HLA-A, -DR and -DQ in 115 patients(More)
We recently identified a naturally occurring soluble form of RAGE (the receptor for advanced glycation endproducts, receptor for AGE) in cultured human vascular cells, and named it endogenous secretory RAGE (esRAGE). esRAGE is generated by alternative RNA splicing and is able to capture AGE, and exerts protection against AGE-induced endothelial cell injury.(More)
OBJECTIVE The objective of this study was to characterize the clinical and immunogenetic features of Japanese pregnancy-associated fulminant type 1 diabetes (PF). A group of patients with PF was compared with a group of patients of child-bearing age with fulminant type 1 diabetes that was not associated with pregnancy (NPF) in a nationwide survey conducted(More)
