Abstract Objectives To evaluate the prevalence and risk factors of new-onset glucose metabolism impairment using an oral glucose tolerance test (OGTT) in patients with normal fasting glycaemia on long-term glucocorticoid (GC) treatment. Methods An OGTT was performed in 150 patients without a previous history of pre-diabetes or diabetes who were diagnosed with inflammatory rheumatic diseases and treated with GCs >3 months. All participants underwent clinical and biochemical evaluation for risk factors of diabetes: age, sex, current and cumulative dose of steroids, treatment duration, waist circumference, BMI, Homeostatic Model Assessment for Insulin Resistance, fasting insulin concentration, family history of diabetes, CRP, 28-joint DAS with CRP, type of connective tissue disease and trunk fat percentage measured by DXA. Logistic regression analysis was conducted to evaluate the association between the presence of impaired glucose tolerance (IGT) in the OGTT and analysed risk factors. Results A total of 102 patients (68%) had fully normal glucose tolerance. Diabetes, isolated impaired fasting glucose, isolated IGT and combined impaired fasting glucose + IGT was diagnosed in 3.3, 4.67, 19.33 and 4.67% of patients, respectively; 20% of participants had IGT or diabetes despite normal fasting glucose concentration. The median cumulative dose and current dose (5 mg) of GCs and treatment duration were similar compared with the normal glucose tolerance group. In a multivariate logistic regression model, only older age (particularly ≥50 years of age) and trunk fat percentage remained significant factors predicting IGT or diabetes in the OGTT. Conclusion New-onset GC-induced glucose intolerance, even in patients on long-term low-dose treatment, is prevalent despite normal fasting glucose concentration and patients should be screened with an OGTT despite the absence of classic risk factors of diabetes.

Hypertriglyceridemia is an important risk factor associated with insulin resistance andβ-cell dysfunction. This study investigated the effects of hypertriglyceridemia and fenofibrate treatment on insulin sensitivity andβ-cell function in subjects with normal glucose tolerance. A total of 1974 subjects with normal glucose tolerance were divided into the normal TG group (NTG group,n=1302) and hypertriglyceridemia group (HTG group,n=672). Next, 92 patients selected randomly from 672 patients with hypertriglyceridemia were assigned to a 24-week fenofibrate treatment. The HTG group had increased waist circumference (WC), body mass index (BMI), homeostasis model assessment of insulin resistance (HOMA-IR), and homeostasis model assessment ofβ-cell function (HOMA-β) and decreased high-density lipoprotein cholesterol (HDL-C) compared with the NTG group (allP<0.01). The 24-week fenofibrate treatment significantly decreased the WC, BMI, TG, HOMA-IR, and HOMA-βlevels and increased the HDL-C levels in the patients with hypertriglyceridemia (WC, BMI, and HOMA-IR:P<0.05; TG, HDL-C, and HOMA-β:P<0.01). The fenofibrate treatment significantly alleviated insulin resistance and reduced the secreting load ofβ-cells in the hypertriglyceridemia patients with normal glucose tolerance.

Abstract Background: The subjects with impaired glucose tolerance have an increased risk for future type 2 diabetes (T2DM); however, a significant number of individuals who develop T2DM have normal glucose tolerance (NGT) at baseline. The study aims to compare glycated hemoglobin (HbA1C) and homeostasis model assessment (HOMA-IR) levels to 30, 60 and 90-min glucose levels in subjects with NGT. Methods: A 75-g oral glucose tolerance test (OGTT) at 0, 30, 60, 90 and 120-min was performed in 1118 subjects without known T2DM. Blood samples were also drawn for fasting insulin and HbA1C levels. Results: Forty percent of the subjects with NGT had increased post-challenge values above the determined optimal glucose levels (10.2, 10.3 and 8.9 mmol/L at 30, 60 and 90-min, respectively). Compared to the subjects with NGT whose glucose levels were below the determined optimal values at 30, 60 and 90-min, we found significantly elevated HbA1C and HOMA-IR levels in the subjects with NGT whose glucose levels were above the determined optimal values (p<0.001). Conclusions: We conclude that the subjects with NGT have different HbA1C and HOMA-IR levels considering glucose levels measured earlier than at 2-h during OGTT. Further well-designed prospective studies are needed to define the significance of 30-min, 60-min and 90-min glucose levels in the prediction of disease in subjects with T2DM.
