Abstract

BACKGROUND: The oral glucose tolerance test (OGTT)-glucose response curves (GRCs; incessant increase, monophasic, and biphasic) reflect insulin sensitivity and β-cell function, being worse in the former and superior in the latter. Here, we examined if the OGTT-GRC pattern is worse in obese antibody (glutamic acid decarboxylase 65-kDa [GAD65] and insulinoma-associated protein-2 [IA-2])-positive (Ab

METHODS: Forty-seven obese youth, 15 Ab

RESULTS: Incessant increase OGTT-GRC is the most frequent curve type and is three-fold higher in Ab

CONCLUSION: Severe insulin deficiency, a characteristic of type 1 diabetes, seems to be related to higher prevalence of incessant increase in Ab
