Tyg Index

The triglyceride glucose (TyG) index has been suggested as a marker for insulin resistance; however, few studies have investigated the clinical implications of markers that combine obesity markers with the TyG index. This study aimed to investigate the associations between non-alcoholic fatty liver disease (NAFLD) and TyG-related markers in healthy subjects in Korea. We enrolled 21,001 asymptomatic participants who underwent hepatic ultrasonography. The homeostasis model assessment of insulin resistance (HOMA-IR), TyG index, TyG-body mass index, and TyG-waist circumference (WC) were subsequently analyzed. NAFLD was diagnosed using hepatic ultrasonography. A multiple logistic regression analysis was performed to evaluate the associations between the quartiles of each parameter and the risk of NAFLD. The increase in the NAFLD risk was most evident when the TyG-WC quartiles were applied; the multivariate-adjusted odds ratios for NAFLD were 4.72 (3.65–6.10), 13.28 (10.23–17.24), and 41.57 (31.66–54.59) in the 2nd, 3rd, and 4th TyG-WC quartiles, respectively, when compared with the lowest quartile. The predictability of the TyG-WC for NAFLD was better than that of the HOMA-IR using the area under the curve. The TyG-WC index was superior to the HOMA-IR for identifying NAFLD in healthy Korean adults, especially in the non-obese population.

A higher sodium intake is conceivably associated with insulin resistant conditions like obesity, but associations of non-alcoholic fatty liver disease (NAFLD) with a higher sodium intake determined by 24 hours (24 h) urine collections are still unclear. Dietary sodium intake was measured by sodium excretion in two complete consecutive 24 h urine collections in 6132 participants of the Prevention of Renal and Vascular End-Stage Disease (PREVEND) cohort. Fatty Liver Index (FLI) ≥60 and Hepatic Steatosis Index (HSI) >36 were used as proxies of suspected NAFLD. 1936 (31.6%) participants had an FLI ≥60, coinciding with the increased prevalence of type 2 diabetes (T2D), metabolic syndrome, hypertension and history of cardiovascular disease. Sodium intake was higher in participants with an FLI ≥60 (163.63 ± 61.81 mmol/24 h vs. 136.76 ± 50.90 mmol/24 h, p < 0.001), with increasing incidence in ascending quartile categories of sodium intake (p < 0.001). Multivariably, an FLI ≥60 was positively associated with a higher sodium intake when taking account for T2D, a positive cardiovascular history, hypertension, alcohol intake, smoking and medication use (odds ratio (OR) 1.54, 95% confidence interval (CI) 1.44–1.64, p < 0.001). Additional adjustment for the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) diminished this association (OR 1.30, 95% CI 1.21–1.41, p < 0.001). HSI >36 showed similar results. Associations remained essentially unaltered after adjustment for body surface area or waist/hip ratio. In conclusion, suspected NAFLD is a feature of higher sodium intake. Insulin resistance-related processes may contribute to the association of NAFLD with sodium intake.

Alcoholic Fatty Liver Disease

Early detection of insulin resistance (IR) or non-alcoholic fatty liver disease (NAFLD) is crucial to preventing future risks of developing chronic diseases. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), Liver Fat Score (LFS), and Fatty Liver Index (FLI) are generally employed to measure severity stages of IR and NAFLD. The study of gene expressions could explain the molecular mechanisms that occur early on in IR and NAFLD; thus providing potential early markers for both diseases. This study was conducted to evaluate the gene expressions that could potentially be early markers of IR and NAFLD. All participants (n = 21) had normal blood glucose and were categorized as without hepatosteatosis (n = 10), at higher risk of hepatosteatosis (n = 6), and hepatosteatosis (n = 5). Gene expression analysis was performed using the 2-∆∆CT relative quantification method. There were significant differences in galnt2 (p < 0.002) and sirt1 (p < 0.010) expression between the first and the third tertiles of HOMA-IR; and in ptpn1 (p < 0.012) expression between the first and the second tertiles of LFS. In conclusion, the expressions of galnt2 and sirt1 could be used as early markers of IR, while the expression of ptpn1 could be employed as an early marker of NAFLD.

AbstractIt is suggested that estrogen protects premenopausal women against non-alcoholic fatty liver disease. From another perspective, the relation between metabolic syndrome (MetS) and non-alcoholic fatty liver disease (NAFLD) is bidirectional. Role of insulin resistance (IR) in NAFLD continues to be a matter of debate. The present study aimed to assess the relation between IR and NAFLD in premenopausal women with MetS. The study included 51 premenopausal women with MetS. In addition, there were 40 age-matched healthy controls. All participants were subjected to careful history taking and thorough clinical examination. Performed laboratory investigations included fasting blood glucose, fasting insulin, lipid profile, and liver functions. Calculation of IR was achieved by the Homeostasis Model Assessment (HOMA-IR). NAFLD was graded into three grades according to findings of abdominal ultrasound. Patients had significantly higher BMI, SBP, DBP, FBG, fasting insulin, HOMA-IR, total cholesterol, triglycerides, and LDL levels when compared with controls. They also had significantly lower HDL levels in comparison to controls. Moreover, they have more advanced grades of NAFLD in contrast to controls. Comparison between patients with various grades of NAFLD regarding the clinical data revealed significant increase of fasting insulin and HOMA-IR levels with advancing NAFLD grade. Using multivariate regression analysis, HOMA-IR was an independent predictor of advanced NAFLD grade. In conclusion, the present study documented a combined inter-relation between MetS, IR, and NAFLD in premenopausal women with MetS. IR is correlated with NAFLD grade.

Background: The true prevalence of both NAFLD and NASH are elusive but estimates based on imaging and autopsy studies suggest that about 20-30% of the adults in United States and western countries have excess fat accumulation in the liver. About 10% of these, strictly speaking about 2-3% of the adult population fulfils the criteria of NASH. True prevalence of NAFLD in Indian patients is not known. So, this study was planned to look for current trend of NAFLD in Indian patients.Methods: This prospective observational study was conducted in the Department of Medicine on 65 patients with ultra-sonography finding of fatty liver disease with no history of alcohol, in one year study duration.Results: It is observed that maximum patients are of middle age from age 31-60 years comprising 76% of patients. Out of total patients, 34% and 66% were males and females respectively. Out of 65 patients, 45(69%) had obesity and maximum number of the patients had waist hip ratio and neck circumference more than the cut off value. Out of 65 patients, 19(29%) had hypercholesterolemia and 42(65%) had hyper-triglyceridemia. Out of 65 patients, 32(49%) had higher alanine transaminase (ALT) level and 17(29%) patients had higher AST level. Out of 65 patients, 29(45%) had the homeostasis model assessment of insulin resistance (HOMA-IR) less than cut off value (less than 2.25) and remaining 36(55%) were having HOMA-IR more than 2.25. The sensitivity for the cut off value for HOMA-IR is 72.7% and specificity is 49.1%.Conclusions: Obesity, neck circumference, and waist hip ratio are higher than its cut off value for both sex, insulin resistance evaluated through HOMA- IR  directly relates to the causation of NAFLD but at some extents higher triglyceride levels are also associated but the values of ALT and AST levels did not give any clue in these cases of NAFLD.

In China, Trapa quadrispinosa (also called water caltrop) has long been used as a function food and folk medicine to treat diabetes mellitus for years. In the present study, the extract of T. quadrispinosa pericarp (TQPE) which mainly contains hydrolysable tannins was prepared to investigate the potential therapeutic action in non-alcoholic fatty liver disease (NAFLD) mice induced by high fat-diet (HFD). After the administration of TQPE (15, 30 mg/kg/day) for 8 weeks, the increased weight of body and liver were significantly suppressed. TQPE also ameliorated liver lipid deposition and reduced lipids parameters of blood in mice. Moreover, TQPE attenuated oxidative stress and showed a hepatoprotective effect in mice. TQPE was also found to decrease the value of homeostatic model assessment for insulin resistance. In addition, TQPE administration increased the phosphorylation of AMP-activated protein kinase (AMPK) and Acetyl-CoA carboxylase (ACC) and inhibited sterol regulatory element-binding protein (SREBP) in the liver tissue. Meanwhile, TQPE elevated insulin receptor substrate-1 (IRs-1) and protein kinase B (Akt) phosphorylation. These results reflected that, as a nature product, TQPE is a potential agent for suppressing the process of NAFLD via regulation of the AMPK/SREBP/ACC and IRs-1/Akt pathways.

Abstract Background: Dipeptidyl peptidase 4 (DPP4) is a serine exopeptidase able to inactivate various oligopeptides and also a hepatokine. Hepatocyte-specific overexpression of DPP4 is associated with hepatic insulin resistance and liver steatosis. Method: We examined whether weekly DPP4 inhibitor omarigliptin (OMG) improves liver function as well as levels of inflammation and insulin resistance in type 2 diabetic patients with non-alcoholic fatty liver disease (NAFLD). Furthermore, we tried OMG in a diabetic patient with biopsy-confirmed nonalcoholic steatohepatitis (NASH). Results: In NAFLD patients, OMG significantly decreased levels of aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (gGTP), homeostatic model assessment of insulin resistance (HOMA-IR), and high-sensitivity C-reactive protein (hsCRP), while no significant change was seen in hemoglobin A1c (HbA1c) or body mass index (BMI). In a NASH patient, liver function had improved markedly, and the hepatic fibrosis marker FIB-4 decreased in parallel with HOMA-IR and hsCRP. Improvements in intrahepatic fat deposition and fibrosis appeared to be seen on ultrasonography.Conclusion: The effects of OMG in ameliorating hepatic insulin resistance may lead to decreasing intrahepatic fat accumulation and improving intrahepatic adipose inflammation in NAFLD/NASH.Trial registration: UMIN Clinical Registry (UMIN000029288).

Dietary habits and gut microbiota play an essential role in non-alcoholic fatty liver disease (NAFLD) and related factors such as insulin resistance and de novo lipogenesis. In this study, we investigated the protective effects of Bacteroides uniformis CBA7346, isolated from the gut of healthy Koreans, on mice with high-fat diet (HFD)-induced NAFLD. Administration of B. uniformis CBA7346 reduced body and liver weight gain, serum alanine aminotransferase and aspartate aminotransferase levels, liver steatosis, and liver triglyceride levels in mice on an HFD; the strain also decreased homeostatic model assessment for insulin resistance values, as well as serum cholesterol, triglyceride, lipopolysaccharide, leptin, and adiponectin levels in mice on an HFD. Moreover, B. uniformis CBA7346 controlled fatty liver disease by attenuating steatosis and inflammation and regulating de novo lipogenesis-related proteins in mice on an HFD. Taken together, these findings suggest that B. uniformis CBA7346 ameliorates HFD-induced NAFLD by reducing insulin resistance and regulating de novo lipogenesis in obese mice.
