Abstract
The onset of fulminant type 1 diabetes mellitus is sometimes accompanied by sudden death or cardiac arrest. The aim of this study was to determine the risk factors for the development of these conditions at the onset of fulminant type 1 diabetes mellitus. We conducted a search of the literature on fulminant type 1 diabetes and sudden death or cardiac arrest published up to 2012 in PubMed and Ichushi (a Japanese article database), and a questionnaire survey was administered to the authors of the articles and to diabetes specialists affiliated to the Japan Diabetes Society. We analyzed the clinical data at disease onset of 17 patients with fulminant type 1 diabetes mellitus who experienced sudden death or cardiac arrest, and those of 257 patients who did not develop these conditions. Patients with sudden death or cardiac arrest were younger, had a higher rate of impaired consciousness, more severe acidosis, hyperglycemia, hyponatremia, hyperkalemia, and hypochloremia, a higher serum blood urea nitrogen level, a higher serum creatinine level, and a higher plasma osmolality level than the other patients. In multiple logistic regression analyses, plasma glucose level was positively associated with sudden death or cardiac arrest. Receiver operating characteristic curve analyses showed that patients with a plasma glucose level over 1000mg/dl (55.5mmol/l) were at a high risk of cardiac arrest. Severe metabolic derangement, especially a high plasma glucose level, is associated with sudden death or cardiac arrest at the onset of fulminant type 1 diabetes mellitus.
