In patients with portal hypertension, plasma insulin levels were raised both fasting and after oral glucose or intravenous tolbutamide. This supports previous suggestions that resistance to endogenous insulin plays a major role in producing the impaired glucose tolerance found in chronic hepatic dysfunction. The operation of portacaval anastomosis was followed by impaired oral fructose toleranc...

Aims We contrasted impaired glucose regulation (prediabetes) prevalence, defined according to oral glucose tolerance test or HbA1c values, and studied cross-sectional associations between prediabetes and subclinical/clinical cardiovascular disease (CVD) in a cohort of European and South Asian origin. Methods For 682 European and 520 South Asian men and women, aged 58–85 years, glycaemic status ...

Background: Environmental pollutants including organophosphate insecticides impair glucose metabolism by altering hepatic oxidation and play an important role in the development of diabetes and its complications. The aim of this study was to assess the impacts of repeated oral doses of Diazinon, an organophosphate insecticide, which is known to impair the glucose metabolism and its tolerance th...

BACKGROUND Specific oral tolerance induction (SOTI) seems to be a promising treatment of food allergy. Specific oral tolerance induction and elimination diet were compared with respect to efficacy rate and patterns of clinical reaction. METHODS Children with challenge proven immunoglobulin E (IgE)-mediated cow's milk (CM) allergy or hen's egg (HE) allergy were randomly assigned to SOTI or eli...

We found that feeding keyhole limpet hemocyanin (KLH) to CD8-deficient (CD8-/-) mice induced oral tolerance that was comparable in both magnitude and quality to that induced in wild-type (wt) mice. The tolerance was dose dependent, and only higher doses of KLH caused significant reduction in specific Ab and T cell responses. Both Th1 and Th2 CD4+ T cell functions were affected. Feeding KLH toge...

Introduction Impaired glucose tolerance (IGT) is diagnosed by a standardized oral glucose tolerance test (OGTT). However, the OGTT is laborious, and when not performed, glucose tolerance cannot be determined from fasting samples retrospectively. We tested if glucose tolerance status is reasonably predictable from a combination of demographic, anthropometric, and laboratory data assessed at one ...

BACKGROUND In cystic fibrosis, highly variable glucose tolerance is suspected. However, no study provided within-patient coefficients of variation. The main objective of this short report was to evaluate within-patient variability of oral glucose tolerance. METHODS In total, 4,643 standardized oral glucose tolerance tests of 1,128 cystic fibrosis patients (median age at first test: 15.5 [11.5...

We present a minimal model for analyzing Oral Glucose Tolerance Test (OGTT) data base on system of 5 ODEs. The model has 4 unknown parameters which are inferred using a Bayesian approach. Preliminarily results are shown with three real patient data.

OBJECTIVE To quantitate the separate impact of obesity and hyperglycemia on the incretin effect (i.e., the gain in beta-cell function after oral glucose versus intravenous glucose). RESEARCH DESIGN AND METHODS Isoglycemic oral (75 g) and intravenous glucose administration was performed in 51 subjects (24 with normal glucose tolerance [NGT], 17 with impaired glucose tolerance [IGT], and 10 wit...
