BMC Endocr Disord 2021; 21:124. [PMID: 34134670 PMCID: PMC8207623 DOI: 10.1186/s12902-021-00788-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Accepted: 05/10/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Although there is abundant evidence indicating the relative contribution of insulin resistance (HOMA-IR) and β-cell dysfunction (HOMA-β) among first-degree relatives (FDRs) of Type 2 DM patients, few studies reported the association between HOMA-IR and HOMA-β with metabolic syndrome. Our objective was to evaluate the impact of metabolic syndrome factors on HOMA-IR, HOMA-β and glycoproteins in non-diabetic FDRs. METHODS In this study, 103 Yemeni male subjects aged 25-42 years, with BMI < 25 kg/m2 were examined, 39 of whom were normal subjects with no family history of diabetes served as control and 64 subjects were non-diabetic FDRs of Type 2 DM patients. RESULTS Both glycoproteins, glycated haemoglobin (HbA1c) and fructosamine as well as insulin, HOMA-IR and HOMA-β were significantly (p = 4.9 × 10-9; 6.0 × 10-8; 6.6 × 10-12; 1.3 × 10-7; 5.5 × 10-12, respectively) higher in non-diabetic FDRs as compared to control group. Fasting plasma glucose, though within normal range, were significantly (p = 0.026) higher in non-diabetic FDRs. Linear regression analysis showed that both TG and WC are the main metabolic syndrome factors that significantly increased HOMA-IR (B = 0.334, p = 1.97 × 10-6; B = 0.024, p = 1.05 × 10-5), HOMA-β (B = 16.8, p = 6.8 × 10-5; B = 0.95, p = 0.004), insulin (B = 16.5, p = 1.2 × 10-6; B = 1.19, p = 8.3 × 10-6) and HbA1c (B = 0.001, p = 0.034; B = 0.007, p = 0.037). CONCLUSION Triglyceride and WC are the important metabolic syndrome factors associated with insulin resistance, basal β-cell function and insulin levels in non-diabetic FDR men of Type 2 DM patients. Moreover, FDRs showed insulin resistance with compensatory β-cell function (hyperinsulinaemia) suggesting that insulin resistance precede the development of pancreatic β-cell dysfunction in individuals at risk of Type 2 DM.

Circulating triacylglycerols but not pancreatic fat associate with insulin secretion in healthy humans. Metabolism 2018; 81:113-125. [PMID: 29273469 DOI: 10.1016/j.metabol.2017.12.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2017] [Revised: 11/08/2017] [Accepted: 12/13/2017] [Indexed: 12/31/2022]
Abstract
BACKGROUND Loss of adequate insulin secretion for the prevailing insulin resistance is critical for the development of type 2 diabetes and has been suggested to result from circulating lipids (triacylglycerols [TG] or free fatty acids) and/or adipocytokines or from ectopic lipid storage in the pancreas. This study aimed to address whether circulating lipids, adipocytokines or pancreatic fat primarily associates with lower insulin secretion. SUBJECTS/METHODS Nondiabetic persons (n=73), recruited from the general population, underwent clinical examinations, fasting blood drawing to measure TG and adipocytokines and oral glucose tolerance testing (OGTT) to assess basal and dynamic insulin secretion and sensitivity indices. Magnetic resonance imaging and 1H-magnetic resonance spectroscopy were used to measure body fat distribution and ectopic fat content in liver and pancreas. RESULTS In age-, sex- and BMI-adjusted analyses, total and high-molecular-weight adiponectin were the strongest negative predictors of fasting beta-cell function (BCF; β=-0.403, p=0.0003 and β=-0.237, p=0.01, respectively) and adaptation index (AI; β=-0.210, p=0.006 and β=-0.133, p=0.02, respectively). Circulating TG, but not pancreatic fat content, related positively to BCF (β=0.375, p<0.0001) and AI (β=0.192, p=0.003). Similar results were obtained for the disposition index (DI). CONCLUSIONS The association of serum lipids and adiponectin with beta-cell function may represent a compensatory response to adapt for lower insulin sensitivity in nondiabetic humans.

The impact of parental history of type 2 diabetes on hyperinsulinemia and insulin resistance in subjects from central Mexico. Diabetes Metab Syndr 2017; 11 Suppl 2:S895-S900. [PMID: 28697997 DOI: 10.1016/j.dsx.2017.07.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2017] [Accepted: 07/01/2017] [Indexed: 01/16/2023]
Abstract
AIMS Hyperinsulinemia and insulin resistance are both associated with the development of Type 2 Diabetes and other pathologies; however, the influence of parental history of Type 2 diabetes (PH-T2D) has yet to be investigated. Therefore, this study was conducted to determine the effect of PH-T2D has on the risk of developing hyperinsulinemia and IR. MATERIALS AND METHODS 1092 subjects (703 non-pregnant females and 389 males) were enrolled for a cross-sectional study. Clinical and biochemical parameters were collected. Subjects were allocated according to their PH-T2D: no parents, one parent, or both parents. Insulin resistance was calculated using the HOMA1 equation (HOMA1-IR). Logistic regression was used to determine the association (odds ratio) between PH-T2D and hyperinsulinemia or insulin resistance. RESULTS Increasing degrees of PH-T2D were associated with significant increases in fasting plasma glucose, insulin, and HOMA1-IR (p <0.05). Subjects having one or both parents were associated with an increase risk of developing hyperinsulinemia (odds ratio=1.53, 95%CI: 1.12-2.09, and odds ratio=1.92, 95%CI: 1.21-3.06, respectively) and insulin resistance (odds ratio=1.47, 95%CI: 1.08-2.00 and odds ratio=1.77, 95%CI: 1.09-2.87, respectively), when adjusting for age, sex, BMI, fasting plasma glucose, and triglycerides. CONCLUSION The presences of PH-T2D significantly increased the risk of developing hyperinsulinemia and insulin resistance.

Abstract
AIM This study aimed to compare plasma copeptin levels, the c-terminal of provasopressin, between individuals with bipolar disorder (BD) and healthy controls and to assess the relation between copeptin and metabolic parameters. METHODS We measured plasma levels of copeptin in individuals with BD (n = 55) and healthy controls (n = 21). Information related to psychiatric/medical history, as well as to metabolic comorbidities and laboratorial parameters was also captured. Insulin resistance and β-cell function in basal state were calculated from fasting plasma glucose and C-peptide using the HOMA2 calculator. Impaired glucose metabolism was defined as pre-diabetes or type 2 diabetes mellitus. Copeptin, adiponectin, and leptin plasma levels were determined by enzyme-linked immunosorbent assay. RESULTS Plasma copeptin levels were lower in individuals with BD, relative to healthy controls (P < 0.001). There were significant interactions between BD and plasma copeptin on β-cell function (rate ratio [RR] = 1.048; P = 0.030) and on leptin levels (RR = 1.087; P = 0.012), indicating that there was a positive correlation between these markers in the BD group, but a negative one in healthy controls. Finally, in individuals with BD only, the association between β-cell function, body mass index (RR = 1.007; P < 0.001), and insulin resistance (RR = 1.001; P = 0.037) was moderated by copeptin levels. CONCLUSION Copeptin levels were lower in individuals with BD than in healthy controls. There were differential associations between copeptin and metabolic parameters within the BD and healthy control subgroups, suggesting an association between abnormal copeptin and metabolic dysregulation only in the BD population.

Abstract
BACKGROUND Metabolic Syndrome (MetS) is associated with elevated risk for developing diabetes and cardiovascular disease. A key component of MetS is the development of insulin resistance (IR). The homeostatic model assessment (HOMA) model can determine IR by using insulin or C-peptide concentrations; however, the efficiency of insulin and C-peptide to determine MetS has not been compared. The aim of the study was to compare the efficiency of C-peptide and insulin to determine MetS in Mexicans. METHODS Anthropometrics, glucose, insulin, C-peptide, triglycerides, and high-density lipoproteins were determined in 156 nonpregnant females and 114 males. Subjects were separated into normal or positive for MetS. IR was determined by the HOMA2 calculator using insulin or C-peptide. Correlations were calculated using the Spearman correlation coefficient (ρ). Differences between correlations were determined by calculating Steiger's Z. The sensitivity was determined by the area under receiver operating characteristics curve (AUC) analysis. RESULTS Independent of the MetS definition [Adult Treatment Panel III (ATP III), International Diabetes Federation (IDF), or World Health Organization (WHO)], C-peptide and insulin were significantly higher in MetS subjects (P < 0.05). C-peptide and insulin correlated with all components of MetS; however, for waist circumference, waist-to-hip ratio, and fasting plasma glucose, C-peptide correlated better than insulin (P < 0.05). Moreover, C-peptide (AUC = 0.72-0.78) was a better marker than insulin (AUC = 0.62-0.72) for MetS (P < 0.05). Finally, HOMA2-IR calculated with C-peptide (AUC = 0.80-0.84) was more accurate than HOMA2-IR calculated with insulin (AUC = 0.68-0.75, P < 0.05) at determining MetS. CONCLUSION C-peptide is a strong indicator of MetS. Since C-peptide has recently emerged as a biomolecule with significant importance for inflammatory diseases, monitoring C-peptide levels will aid clinicians in preventing MetS.
