Background: Type 2 diabetes mellitus (T2DM) is an emerging disease in the pediatric population. The association between T2DM and non-alcoholic fatty liver disease (NAFLD) has been described. Recent evidence suggests that sizes and composition of high-density lipoprotein (HDL) may be more important that HDL-C levels in predicting coronary heart disease. There is not data regarding the HDL subclasses distribution and composition in T2DM youths with NAFLD., Methods: This cross-sectional study included 47 adolescents with T2DM and 23 non-diabetic controls of both sexes aged 10 to 18 years. The presence of NAFLD was determined estimated proton density fat fraction (PDFF) by magnetic resonance by spectroscopy. We compared the HDL subclasses distribution (HDL2b, HDL2a, HDL3a HDL3b and HDL3c) and the HDL chemical composition (total protein, triglyceride, phospholipid, cholesteryl esters, and free cholesterol) between the groups of adolescents with T2DM and the control group., Results: Patients with T2DM and NAFLD had a significantly lower proportion HDL2b (P = .040) and a higher proportion of HDL3c (P = .035); higher proportion of TG (P = .032) and a lower CE (P = .002) and FC (P < .001). A negative association was observed between PDFF and the percentages of HDL2b (r 2 = -0.341, P = .004) and the average particle size (r 2 = -0.327, P = .05), and a positive association with HDL3c subpopulations (r 2 = 0.327, P = .015); about composition inside HDL particle, a positive association with PDFF and the TG (r 2 = 0.299, P = .013) and negative with CE (r 2 = -0.265, P = .030)., Conclusions: In adolescents diagnosed with T2DM, the presence of NAFLD is associated with abnormalities in the distribution of HDL subpopulations and the lipid composition of HDL particles., (© 2020 John Wiley & Sons A/S .

Introduction and Aim: Association of vitamin D deficiency (VDD) with fatty liver (FL) disease is controversial. The purpose of this study was to analyze the association of VDD with FL., Material and Methods: Cross-sectional study. Data on cardiovascular risk factors, medications, alcohol intake, smoking, diet, and physical activity were obtained. Biochemical, anthropometric, and blood pressure variables were measured. The 25-hydroxyvitamin D (25(OH)D) was quantified through chemoluminescence. The presence of FL, defined as a liver/spleen attenuation index lower than 1.0, was identified through computed axial tomography (CAT)., Results: The study included 1,467 subjects (49.7% men) with a mean age of 53.3 ± 9.3 years and BMI of 28.3 ± 4.0 kg/m2. Only 11% had optimum values of vitamin D, and 25(OH)D concentration was lower in participants with FL. Multivariate logistic regression models, adjusted for age, gender, BMI, sampling season, glucose, total cholesterol, triglycerides, HOMA-IR, hs-CRP, ALT, AST, and elevated VAT, revealed an association between FL and vitamin D (VD) insufficiency (RM 1.61 [0.99-2.61]) and with VDD (RM 1.68 [1.02-2.77]); however, statistical significance was lost when including caloric consumption and physical activity in the model., Conclusions: In Mexican adults, deficient VD concentration and FL were not independently associated of caloric consumption and physical activity.

Background and Rationale: Fatty liver (FL) and abdominal visceral fat (AVF) are strongly associated with systemic inflammation, however, it has not been defined if each one is independently involved, and if the insulin resistance is associated. To investigate if FL, AVF and insulin resistance are independently or additively associated with the high-sensitivity C-reactive protein (hs-CRP) in subjects without coronary artery disease we included 491 men and 553 women., Material and Methods: All had anthropometric and plasma biochemical measurements, FL and AVF assessments by computed tomography., Results: The FL prevalence was 35.6% in men and 28.0% in women, p < 0.01. The prevalence of obesity, metabolic syndrome and homeostasis model assessment of insulin resistance (HOMA-IR) was significantly higher in FL compared to non FL subjects. FL and AVF accounted for 21 and 17%, respectively, to hs-CRP plasma levels. FL, AVF ≥ P75 and HOMA-IR ≥ P75 were independently and additively associated with plasma hs-CRP. The risk of hs-CRP ≥ 3 mg/L increased progressively in men from 1.36 (0.5-3.86) through 3.58 (1.32-9.7) in those with 1 or 3 factors respectively. In women from 2.25 (1.2-4.2) to 4.67 (2.3-9.4), respectively. In conclusion, both the FL and hs-CRP ≥ 3 mg/L occur in 1 of every 3 non CAD subjects. In men, FL and AVF ≥ P75 were associated with 3.6 times the risk of hs-CRP ≥ 3 mg/L, while in women, these factors were independently and additively associated with a 4.7 times higher risk of systemic inflammation.

Introduction: Individuals with fatty liver (FL) have an increased risk of coronary artery disease (CAD) probably due to its association with cardiometabolic risk factors (CMRF)., Objective: To know the prevalence of FL and analyze its association with CMRF and subclinical atherosclerosis, in a sample of Mexican Mestizo population., Material and Methods: This study included 846 subjects from the Genetic of Atherosclerosis Disease (GEA) study (53 ± 9 years, 50.7% women) without diabetes and no personal or family history of premature CAD. Blood samples were taken for measurements of lipids profile, uric acid, and insulin. The presence of FL was identified by computed tomography. Carotid intima media thickness (CIMT) was measured by B mode ultrasound, using the > 75 percentile as cutoff value to define subclinical atherosclerosis., Results: The general prevalence of FL was 32.4%. In men, FL was associated with hyperuricemia, whereas in women, hyperuricemia, low level of high density lipoprotein cholesterol, and metabolic syndrome were the factors associated with this hepatic alteration. In women, FL was associated with a 66% higher probability of having high CIMT, independently of age, hypertension, dyslipidemia, and waist circumference, but not of HOMA-IR., Conclusions: In women, FL was associated with the presence of subclinical atherosclerosis independently of traditional CMRF. Our study suggests that, in women, insulin resistance could be a mediator of metabolic abnormalities and of subclinical atherosclerosis.

Background: The association of subclinical hypothyroidism (SCH) with insulin resistance, metabolic syndrome (MS), and coronary atherosclerosis is uncertain., Objective: To investigate the role of increased intrahepatic fat in the association of SCH with insulin resistance, MS, and coronary atherosclerosis., Design, Patients, and Methods: We conducted a cross-sectional study in a sample of 753 subjects (46% males) aged 35-70 years with no history of diabetes, renal, hepatic, thyroid, or coronary heart disease, and were participants of the Genetics of Atherosclerotic Disease study. SCH was defined as a high serum TSH level with normal free thyroxine concentration. Fatty liver (FL), coronary artery calcification (CAC), and abdominal visceral adipose tissue were assessed by computed tomography. Cross-sectional associations of SCH with and without FL, with MS, insulin resistance, and subclinical atherosclerosis defined as a CAC score >0, were examined in logistic regression models., Results: SCH was observed in 17.7% of the population studied. The prevalence of FL was similar in both euthyroid and SCH subjects (31.8 vs 27.8%, P=0.371). SCH plus FL subjects were heavier and had more metabolic abnormalities compared with SCH plus normal liver subjects. In multivariate-adjusted logistic regression analyses, SCH plus FL was associated with MS (odds ratio (OR): 2.73, 95% CI: 1.26-5.92), insulin resistance (OR: 4.91, 95% CI: 1.63-14.75), and CAC score >0 (OR: 3.05, 95% CI: 1.20-7.76). SCH without FL showed no associations., Conclusion: SCH with FL is associated with increased odds of MS, insulin resistance, and CAC, independent of potential confounders., (© 2014 European Society of Endocrinology.)

Objective: To analyze the participation of fatty liver (FL) in the association of metabolic syndrome (MS) with type 2 diabetes and coronary artery calcification (CAC)., Research Design and Methods: A total of 765 subjects (52% women) aged 30 to 75 years without clinical atherosclerosis were included in this study. MS was defined in accordance with the Adult Treatment Panel III (ATPIII) guidelines, while FL and CAC were identified by computed tomography., Results: There were increasing frequencies of type 2 diabetes and CAC in all three groups: control, MS without FL, and MS plus FL. Multivariable-adjusted logistic regression analyses showed that FL increased the association of MS with type 2 diabetes in both women [odds ratio 10.6 (95% CI 3.4-33.7)] and men [12.1 (4.1-36.1)]. In women, FL also increased the association of MS with CAC [2.34 (1.07-5.12)]., Conclusions: FL increases the association of MS with type 2 diabetes and subclinical atherosclerosis.
