One-Hour Post-Load Plasma Glucose and Altered Glucometabolic Profile in Youths with Overweight or Obesity. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5961. [PMID: 37297565 PMCID: PMC10252535 DOI: 10.3390/ijerph20115961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 02/04/2023] [Accepted: 05/24/2023] [Indexed: 06/12/2023]
Abstract
In youths, two cut-offs (133 and 155 mg/dL) have been proposed to identify high glucose levels at the 1 h (G60) mark during an oral glucose tolerance test (OGTT). We evaluated which cut-off was more closely associated with isolated impaired glucose tolerance (IGT) and cardiometabolic risk (CMR) in 1199 youth with overweight/obesity (OW/OB) and normal fasting glucose and/or HbA1c. The disposition index (DI) was available in 724 youths. The sample was divided by two cut-offs of G60: <133 mg/dL (n = 853) and ≥133 mg/dL (n = 346), or G60 < 155 mg/dL (n = 1050) and ≥155 mg/dL (n = 149). Independent of the cut-off, youths with high levels of G60 showed higher levels of G120, insulin resistance (IR), triglycerides to HDL ratio (TG/HDL), alanine aminotransferase (ALT), and lower insulin sensitivity (IS) and DI than youths with lower levels of G60. The percentage of youths showing IGT, IR, low IS, high TG/HDL ratio, high ALT, and low DI was 50% higher in the G60 ≥ 133 mg/dL group than in the G60 ≥ 155 mg/dL one. In youths with OW/OB and IGT, a cut-off of G60 ≥ 133 mg/dL is more useful than G60 ≥ 155 mg/dL to identify those at high risk of IGT and altered CMR profile.

De Sanctis V, Soliman A, Tzoulis P, Daar S, Pozzobon GC, Kattamis C. A study of isolated hyperglycemia (blood glucose ≥155 mg/dL) at 1-hour of oral glucose tolerance test (OGTT) in patients with β-transfusion dependent thalassemia (β-TDT) followed for 12 years. ACTA BIO-MEDICA : ATENEI PARMENSIS 2021; 92:e2021322. [PMID: 34487089 PMCID: PMC8477110 DOI: 10.23750/abm.v92i4.11105] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 12/11/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Subjects with normal glucose tolerance (NGT) but 1-hour post-load plasma glucose (1-h OGTT) ≥ 155 mg/dl (8.6 mmol/L; H-NGT) have an increased risk for developing Type 2 diabetes mellitus (T2DM), determining a new risk factor category with deeper metabolic impairment. The aim of this study was to evaluate the H-NGT as a diagnostic predictor of future dysglycemia in β-transfusion dependent thalassemia (β-TDT). Indices of insulin secretion and insulin sensitivity derived at baseline from OGTTs, were also reviewed. STUDY DESIGN AND METHODS OGTT and indices of insulin secretion and insulin sensitivity, derived at baseline during OGTT, in 17 β-TDT with H-NGT and 29 β-TDT with normal OGTT (NGT) and without H-NGT followed for 12 years were studied. RESULTS H-NGT was associated with decreased insulin sensitivity and progressive deterioration of glucose tolerance. At baseline, serum ferritin and serum alanine aminotransferase (ALT) levels were higher in patients with H-NGT compared to patients with NGT. A strong correlation was observed between ALT and 1-hour plasma glucose value during OGTT in the total group of 36 patients . Compliance to iron chelation therapy was poor in β-TDT patients with H-NGT. An inverse correlation was found between 1-hour plasma glucose value during OGTT and insulin secretion-sensitivity index-2 (ISSI-2) (r: -0.3298; p: 0.025), between ISSI-2 and ALT (r: -0.3262; p: 0.027), and between 1-hour plasma glucose value and ISSI-2 (r: -0.537; p: 0.005) in the whole group of β-TDT patients enrolled in our study. CONCLUSIONS This retrospective study displayed that finding an isolated high 1-hour post-load glucose level (≥155 mg/dL; H-NGT) during the OGTT may serve as a simple biomarker to detect high-risk patients, with chronic liver disease and/or iron overload, who need periodic glycemic surveillance. Measuring the ISSI 2 represented another valuable predictive marker in the assessment of glycemia in these patients.

Clin Endocrinol (Oxf) 2018; 89:757-764. [PMID: 30229983 DOI: 10.1111/cen.13859] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 09/10/2018] [Accepted: 09/15/2018] [Indexed: 01/01/2023]
Abstract
CONTEXT Adults with plasma glucose levels at one hour (1h-GL) ≥8.6 mmol/L during an oral glucose tolerance test (OGTT) are at increased risk for type 2 diabetes mellitus and present an unfavourable cardiometabolic and inflammatory profile, but relevant data on children are scarce. OBJECTIVE To investigate if elevated 1h-GL during OGTT in obese children and adolescents is associated with insulin resistance and specific pro-inflammatory biomarkers. RESEARCH DESIGN AND METHODS The study group comprised 88 obese children who attended the Outpatient Pediatric Clinic of our Hospital between January and December 2016. Children were divided into two groups according to 1h-GL during an OGTT: group 1 (n = 57) consisted of those with 1h-GL <8.6 mmol/L and group 2 (n = 31) of those with 1h-GL ≥8.6 mmol/L. Arterial blood pressure, body mass index (BMI) and waist circumference (WC) z-scores were measured in all participants. Specific insulin resistance (IR) indices, that is HOMA-IR, Matsuda index and Cederholm insulin sensitivity index (ISI) were calculated. Further, pro-inflammatory biomarkers that have been correlated with obesity complications, namely adiponectin, leptin, visfatin and interleukin (IL)-6 together with lipid levels were measured in all participants. Logistic regression analysis was used. RESULTS Children in group 2 had higher insulin (15.5 ± 6.4 vs 10.9 ± 4.8 μU/mL), HOMA-IR (3.41 ± 1.4 vs 2.34 ± 1.05) and lower Matsuda index [4.7 (3.1) vs 18.4 (17) median plus IQR] and Cederholm ISI (38 ± 6 vs 56 ± 11), than children in group 1 (all P < 0.001). They also had higher visfatin (15.4 ± 5.2 vs 10.1 ± 7 ng/mL), and IL-6 [12.5 (6.7) vs 4.8 (4.4) pg/mL], and lower adiponectin (5.9 ± 3.4 vs 11.8 ± 4.7 μg/mL) than children in group 1 (all P < 0.001). Logistic regression showed that these differences between the two groups were independent of age, sex, Tanner stage, BMI and WC z-scores. CONCLUSIONS In obese children, 1h-GL ≥8.6 mmol/L during an OGTT is correlated with worsened IR, and an unfavourable metabolic and inflammatory profile. Thus, 1h-GL could be used as an additional marker to identify obese children and adolescents at increased risk of developing obesity complications.

High-fat diet induces a neurometabolic state characterized by changes in glutamate and N-acetylaspartate pools associated with early glucose intolerance: An in vivo multimodal MRI study. J Magn Reson Imaging 2018; 48:757-766. [PMID: 29377412 DOI: 10.1002/jmri.25942] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Accepted: 12/18/2017] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Type-2 diabetes mellitus (T2DM) is a metabolic disorder with a broad range of complications in the brain that depend on the conditions that precede its onset, such as obesity and metabolic syndromes. It has been suggested that neurotransmitter and metabolic perturbations may emerge even before the early stages of T2DM and that high-caloric intake could adversely influence the brain in such states. Notwithstanding, evidence for neurochemical and structural alterations in these conditions are still sparse and controversial. PURPOSE To evaluate the influence of high-fat diet in the neurochemical profile and structural integrity of the rodent brain. STUDY TYPE Prospective. SUBJECTS Wistar rats (n = 12/group). FIELD STRENGTH/SEQUENCE A PRESS, ISIS, RARE, and EPI sequences were performed at 9.4T. ASSESSMENT Neurochemical and structural parameters were assessed by magnetic resonance spectroscopy, voxel-based morphometry, volumetry, and diffusion tensor imaging. STATISTICAL TESTS Measurements were compared through Student and Mann-Whitney tests. Pearson correlation was used to assess relationships between parameters. RESULTS Animals submitted to high-caloric intake gained weight (P = 0.003) and developed glucose intolerance (P < 0.001) but not hyperglycemia. In the hippocampus, the diet induced perturbations in glutamatergic metabolites reflected by increased levels of glutamine (P = 0.016) and glutamatergic pool (Glx) (P = 0.036), which were negatively correlated with glucose intolerance (glutamine, r = -0.804, P = 0.029), suggesting a link with neurometabolic dysregulation. At caudate-putamen, high-fat diet led to a surprising increase in the pool of N-acetylaspartate (P = 0.028). A relation with metabolic changes was again suggested by the negative correlation between glucose intolerance and levels of glutamatergic metabolites in this region (glutamate, r = -0.845, P = 0.014; Glx, r = -0.834, P = 0.020). Neither changes in phosphate compounds nor major structural alterations were observed for both regions. DATA CONCLUSION We found evidence that high-fat diet-induced obesity leads to distinct early and region-specific metabolic/neurochemical imbalances in the presence of early glucose intolerance even when structural alterations or T2DM are absent.

Reducing the prevalence of dysglycemia: is the time ripe to test the effectiveness of intervention in high-risk individuals with elevated 1 h post-load glucose levels? Endocrine 2017; 55:697-701. [PMID: 28124259 DOI: 10.1007/s12020-017-1236-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Accepted: 01/17/2017] [Indexed: 02/07/2023]
Abstract
Identifying the earliest time point on the prediabetic continuum is critical to avoid progressive deterioration in β-cell function. Progressively rising glucose levels even within the "normal range" occur considerably late in the evolution to diabetes thus presenting an important opportunity for earlier diagnosis, treatment, and possible reversal. An elevated 1 h postprandial glucose level, not detected by current diagnostic standards, may provide an opportunity for the early identification of those at risk. When the 1 h post-load glucose level is elevated, lifestyle intervention may have the greatest benefit for preserving β-cell function and prevent further progression to prediabetes and diabetes. In view of the considerable consistent epidemiologic data in large disparate populations supporting the predictive capacity of the1 h post-load value for predicting progression to diabetes and mortality, the time is therefore ripe to evaluate this hypothesis in a large, prospective multicenter randomized trial with lifestyle intervention.
