J Atheroscler Thromb 2024; 31:1620-1633. [PMID: 38777770 PMCID: PMC11537790 DOI: 10.5551/jat.64896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 04/15/2024] [Indexed: 05/25/2024] Open
Abstract
AIM No pharmacotherapeutic treatment has been established for metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH). This trial compared the effects of pemafibrate and omega-3-acid ethyl ester on hepatic function in patients with hypertriglyceridemia complicated by MASLD. METHODS Patients with hypertriglyceridemia complicated by MASLD were enrolled, randomly assigned to the pemafibrate or omega-3-acid ethyl ester group, and followed for 24 weeks. The primary endpoint was the change in alanine aminotransferase (ALT) from baseline to week 24. The secondary endpoints included other hepatic enzymes, lipid profiles, and hepatic fibrosis biomarkers. RESULTS A total of 80 patients were enrolled and randomized. The adjusted mean change in ALT from baseline to week 24 was significantly lower in the pemafibrate group (-19.7±5.9 U/L) than in the omega-3-acid ethyl ester group (6.8±5.5 U/L) (intergroup difference, -26.5 U/L; 95% confidence interval, -42.3 to -10.7 U/L; p=0.001). Pemafibrate significantly improved the levels of other hepatic enzymes (aspartate aminotransferase and gamma-glutamyl transpeptidase), lipid profiles (triglycerides, total cholesterol, high-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol), and hepatic fibrosis biomarkers (Mac-2 binding protein glycan isomer and Fibrosis-4 index). No cases of discontinuation due to adverse drug reactions were identified in either group, and there were no safety concerns. CONCLUSIONS Pemafibrate is recommended over omega-3-acid ethyl ester for lipid management and MASLD treatment in patients with hypertriglyceridemia complicated by MASLD. The study results may contribute to the development of future treatment strategies for patients with MASLD/MASH.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a burgeoning global health concern, closely associated with the rising prevalence of type 2 diabetes mellitus (T2DM) and obesity. This systematic review and meta-analysis aim to comprehensively evaluate the prevalence of NAFLD in DM patients in Saudi Arabia, a country undergoing rapid socioeconomic changes. Our multifaceted search strategy identified four high-quality studies conducted between 2003 and 2022, covering hospital and community settings. The aggregate prevalence rate of NAFLD in DM patients was notably high, ranging from 47.8% to 72.8%. However, substantial heterogeneity (I² = 90.6%) was observed, indicating variability attributed to diverse study characteristics. The uniform application of ultrasound for diagnosis was noteworthy but raised concerns regarding sensitivity. This analysis underscores the urgency of public health measures for early detection and management of NAFLD in DM-prone populations in Saudi Arabia.

Abstract
Liver disease is fast emerging as a global health priority. Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in Western countries, with an increasing prevalence associated with the rising prevalence of diabetes mellitus and obesity. The worldwide prevalence of NAFLD may be in the order of 25%, but in the Middle East, it may be even higher. This study aimed to estimate the prevalence of NAFLD in the Kingdom of Saudi Arabia (KSA). A systematic review and meta-analysis were undertaken. Electronic searches were carried out through Medline, EMBASE, CINAHL, Web of Science, and Google Scholar, for articles from inception to April 2020. Studies conducted on adult populations in any setting reporting NAFLD prevalence were included. Pooled proportions and associated 95% confidence intervals (CIs) were presented in forest plots using a random effect model. Eight studies, including 4045 participants, were included. The pooled prevalence of NAFLD among all adult populations in KSA was 16.8% (11.1%-22.5%). Amongst those with type 2 diabetes, the prevalence was 58.0% (45.0%-70.9%). There were no true general population studies of the prevalence of NAFLD in KSA available. This review suggests that NAFLD is common in the KSA, and that type 2 diabetes is a risk factor in KSA as identified elsewhere in the world.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is an overlooked complication of type 2 diabetes (T2D). Current recommendations for the management of NAFLD are mainly focused on weight reduction, overlooking the role of macronutrient composition. Although dietary carbohydrates play a major role in intrahepatic fat synthesis, their association with the progression of liver steatosis has not been fully investigated in patients with T2D. Aim To investigate the association between higher carbohydrate intake and the presence of liver steatosis in patients with T2D. Methods This cross-sectional study included men and women aged 18-60 years diagnosed with T2D. Anthropometric measurements, hepatic steatosis assessment using the controlled attenuation parameter (CAP), blood samples, and dietary data were analyzed. Participants were divided into two groups: NAFLD and NAFLD-free. A two-sample t-test was used to evaluate the differences between the two groups. Stepwise multiple linear regression models adjusted for potential confounders were used to determine the association between CAP values and higher carbohydrate intake. Results In total, 358 participants were included. NAFLD was present in 79.3% of the participants. Body mass index, waist circumference, ALT, HbA1c, and triglycerides showed direct, while HDL-Cholesterol revealed inverse associations with CAP values. No significant relationship was found between carbohydrate intake and steatosis in the total study sample; however, multiple linear regression analysis revealed a significant relationship between carbohydrate intake and CAP values in patients aged ≤50 years. Conclusion In patients with T2D, higher carbohydrate intake was associated with liver steatosis in those aged 50 years and below. Further studies are required to confirm the causality between carbohydrate intake and liver steatosis.

Abstract
Type 2 diabetes mellitus (T2DM) is a common chronic metabolic disease. Accumulating evidence has demonstrated that nonalcoholic fatty liver disease (NAFLD) shares common typical features with T2DM, and they affect each other extensively. Thus, NAFLD has emerged as a novel target for T2DM prevention and care. Although Corni Fructus (CF) and its extracts have a therapeutic effect on T2DM, its effects and mechanisms on T2DM with NAFLD are far from elucidated. In this study, a mouse model of T2DM with NAFLD complication was established in ICR mice by feeding a high-fat, high-sugar (HFHS) diet and intraperitoneally injecting with a low dose of streptozotocin (STZ). Then, the effects of iridoid glycosides (IG) extracted from CF on this mouse model were investigated. We found that 4-week IG administration remarkably alleviated hyperglycemia and insulin resistance and significantly reduced inflammation, oxidative stress, and fat accumulation in the liver of T2DM with NAFLD mice. Further studies showed that IG inhibited the NF-κB but enhanced the PI3K-AKT signaling pathway. In summary, these results indicated that the IG from CF has potential therapeutic effects on T2DM with NAFLD.

Pancreatic Sirtuin 3 Deficiency Promotes Hepatic Steatosis by Enhancing 5-Hydroxytryptamine Synthesis in Mice With Diet-Induced Obesity. Diabetes 2021; 70:119-131.

Abstract
Sirtuin 3 (SIRT3) is a protein deacetylase regulating β-cell function through inhibiting oxidative stress in obese and diabetic mice, but the detailed mechanism and potential effect of β-cell-specific SIRT3 on metabolic homeostasis, and its potential effect on other metabolic organs, are unknown. We found that glucose tolerance and glucose-stimulated insulin secretion were impaired in high-fat diet (HFD)-fed β-cell-selective Sirt3 knockout (Sirt3 f/f;Cre/+) mice. In addition, Sirt3 f/f;Cre/+ mice had more severe hepatic steatosis than Sirt3 f/f mice upon HFD feeding. RNA sequencing of islets suggested that Sirt3 deficiency overactivated 5-hydroxytryptamine (5-HT) synthesis as evidenced by upregulation of tryptophan hydroxylase 1 (TPH1). 5-HT concentration was increased in both islets and serum of Sirt3 f/f;Cre/+ mice. 5-HT also facilitated the effect of palmitate to increase lipid deposition. Treatment with TPH1 inhibitor ameliorated hepatic steatosis and reduced weight gain in HFD-fed Sirt3 f/f;Cre/+ mice. These data suggested that under HFD feeding, SIRT3 deficiency in β-cells not only regulates insulin secretion but also modulates hepatic lipid metabolism via the release of 5-HT.

Abstract
Studies have showed that dyslipidemia is closely related to nonalcoholic fatty liver disease (NAFLD). However, less attention has been paid to the relationship between early dyslipidemia and long-term risk of NAFLD. Therefore, we aimed to develop a simple-to-use nomogram to predict early dyslipidemia and long-term risk of NAFLD onset.A retrospective cohort study including 3621 employees (including retirees) from 7 companies was conducted between 2012 and 2019. Anthropometric, potential laboratory parameters and abdominal ultrasound were performed at baseline and after a 5-year follow-up. Cox proportional hazards model was used to determine predictors for NAFLD onset. The effects of lipids, age, body mass index (BMI), and serum uric acid (UA) on NAFLD were evaluated with the use of Kaplan-Meier curves (log-rank test). A nomogram was developed based on the Cox proportional hazard model and a 2-piecewise linear regression model. The accuracy of model was evaluated according to the area under the receiver operating characteristic curves.A total of 1545 subjects were included in the final analysis. The mean follow-up time was 52 ± 6.6 months. Of the total subjects, 77.61% were male and 22.39% were female. The mean age at the time of initial visit was 45.21 ± 11.20 years. Five hundred fifty-five subjects (35.92% of all subjects) were finally diagnosed with NAFLD. Variables in the nomogram included age, BMI, triglycerides, high-density lipoprotein, low-density lipoprotein, and UA. The accuracy of the nomogram for predicting 5-year cumulative occurrence of NAFLD was 0.8135 (95% confidence interval: 0.7921-0.8349), and the sensitivity and specificity were 0.8108 and 0.6960, respectively.The combination of age, BMI, triglycerides, high-density lipoprotein, low-density lipoprotein, and UA translated into a nomogram can reliably estimate the incidence of NAFLD within 5 years. It may serve as a decision support tool to determine whether to intervene at an early stage.

Abstract
Background: Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease (CLD). NAFLD is also related to obesity and metabolic syndromes, which are common in Saudi Arabia. However, it is yet unclear what proportion of CLD cases is because of NAFLD in Saudi Arabia. Objective: To investigate the prevalence and clinical characteristics of NAFLD among patients with CLD in Saudi Arabia. Materials and Methods: This retrospective study included all patients with any CLD who had successfully undergone transient elastography (FibroScan) examination at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between April 2015 and April 2018. These CLD patients were then grouped as NAFLD and non-NAFLD patients. Serum hemoglobin, alanine aminotransferase, gamma-glutamyl transferase, albumin and bilirubin levels; platelet count and international normalized ratio within 1 month after the FibroScan examination were assessed. For NAFLD patients, glycated hemoglobin levels and abdominal ultrasound examination results were also assessed. Statistical analysis was carried out using Student’s t-test and linear regression. Results: The prevalence of NAFLD among CLD patients was 22.5% (111 of 494 CLD patients), and it was the third most common CLD after chronic hepatitis B and C. Compared with non-NAFLD patients, NAFLD patients had significantly higher mean age (53.65 ± 12.7 vs. 48.07 ± 14.6 years; P < 0.001), mean serum alanine aminotransferase level (61.84 vs. 50.23 IU/L; P < 0.001) and mean controlled attenuation parameter (297.83 vs. 238.41; P < 0.001). NAFLD patients also had a higher rate of ultrasound-detected features of cirrhosis (16.2% vs. 3.7%, P < 0.001), but there was no significant difference in fibrosis severity. In addition, their mean glycated hemoglobin level (6.85) was elevated (range: 5–13). Age and platelet count were significantly correlated with presence of cirrhosis. Conclusion: NAFLD is the third most common CLD in Western Saudi Arabia, and it is associated with older age and metabolic syndromes, with one-third of the patients having advanced fibrosis or cirrhosis.

Abstract
BACKGROUND/AIM Gallstone disease (GD) and nonalcoholic fatty liver disease (NAFLD) are associated with metabolic syndrome. Despite the benign nature of NAFLD, 10% of patients may develop advanced fibrosis and cirrhosis. We aimed to identify the prevalence and factors associated with NAFLD among GD patients in the Saudi population. PATIENTS AND METHODS This is a single-center, observational cohort study that included patients seen in general surgery clinics at our institution from 2011 to 2017. All liver biopsies were taken at the same time as the cholecystectomy. Demographical and clinical data were prospectively collected from the study population. RESULTS Of the 301 GD patients in the study, 15% had a normal body mass index (BMI), 29% were overweight, and 56% were obese. There were 143 (47.8%) patients with NAFLD, of which 125 (41.8%) showed steatosis and 18 (6%) had nonalcoholic steatohepatitis. There was a significant positive correlation between NAFLD and age (r = 0.243; P < 0.0001), and BMI (r = 0.242; P < 0.0001). Obese patients with BMI 30-40 kg/m[2] were 2.403 (P = 0.039) more likely to have NAFLD compared with normal BMI patients, and this value increased to 6.145 (P = 0.002) in patients with BMI >40 kg/m[2]. Additionally, patients with T2DM were 2.839 times (P = 0.015) more likely to have NAFLD compared with those who did not. CONCLUSIONS The prevalence of NAFLD among GD patients is high. High BMI and diabetes are independent factors associated with NAFLD in GD patients. The results suggest that there may be a need for routine liver biopsy in selected patients during cholecystectomy.

Abstract
Objective: To see the frequency of incidental fatty liver on ultrasound and its association with diabetes mellitus and hypertension. Methods: A cross sectional study was conducted from January 2016 to June 2016 in the department of Surgery and Radiology at Hamdard University Hospital. Patients of both genders and all ages were selected by non purposive convenience sampling. Critically ill, trauma cases and all those patients who had a history of chronic liver disease, alcohol intake and expected pregnancy were excluded. Blood pressure and random blood sugar were recorded. Results: Six hundred patients were included in the study with mean age of 44.65±18.8 years. 240 patients (40%) had incidental finding of fatty liver on ultrasound. Out of 240 with fatty liver patients 117 were males (48.8%) and 123 were females (51.3%). Total 141 patients were diagnosed with hypertension, out of which 81(57.44%, p< 0.001) had fatty liver on ultrasound. Diabetes mellitus was diagnosed in 84 patients, in which 57 patients (67.8%, p<0.001) had fatty liver. Conclusion: Fatty liver is a frequently found incidental finding on ultrasound. There is a significant association of fatty liver with diabetes mellitus and hypertension.

Abstract
Background The effect of cigarette smoking on the onset of nonalcoholic fatty liver disease (NAFLD) is unclear, especially that associated with drinking small amounts of alcohol. We conducted a longitudinal study to investigate the relationship between cigarette smoking and NAFLD onset, which was stratified according to the amount of alcohol consumed. Methods We enrolled 7,905 Japanese subjects who had received annual health checkups more than twice between April 2003 and August 2013, 4,045 of whom met at least one of the following exclusion criteria and were excluded: (a) fatty liver at baseline; (b) hepatitis B or hepatitis C; (c) alcohol consumption (men: ≥210 g/wk; women: ≥140 g/wk); (d) change in alcohol drinking status between baseline and the study’s endpoint; (e) change in cigarette smoking habits between baseline and the study’s endpoint; or (f) current treatment with antidiabetic agents, antihypertensive agents, and/or lipid-lowering agents. The remaining 3,860 subjects (1,512 men, 2,348 women) were divided into two groups based on average alcohol consumption. Results After adjusting for the variables associated with metabolic disease, smoking was associated with fatty liver disease onset compared with nonsmokers in nondrinkers (adjusted hazard ratio = 1.988, 95% confidence interval 1.057–3.595; p = 0.034). No association was found between smoking and fatty liver disease onset in the low alcohol consumption group (men: <210 g alcohol/week; women: <140 g alcohol/week). The fatty liver disease incidence increased significantly among the nondrinkers as the number of cigarettes smoked increased (p = 0.001). Conclusions Cigarette smoking may be a significant risk factor associated with NAFLD onset in nondrinkers. These results may help clinicians to identify patients who are at a high risk of developing NAFLD and to prevent the progression of NAFLD by promoting earlier interventions that help people discontinue unhealthy lifestyle habits.

Abstract
BACKGROUND Considering the clear association between metabolic syndrome and future cardiovascular disease, early detection of metabolic syndrome is important. This study was conducted to assess the correlation between metabolic syndrome components and within-normal-range of liver enzymes in Iranian adults. METHODS This cross-sectional study was comprised of 700 Iranian adults in the districts of East Azerbaijan-Iran in 2015. The levels of lipid profile and glucose were measured by enzymatic colorimetric methods. Weight, height, waist circumferences were measured with standard protocols. Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) were assessed using the ultraviolet method. The Pearson correlation and Logistic regression were used to for statistical analysis. RESULTS With increasing the number of metabolic abnormalities, the mean ALT level was increased significantly (Ptrend=0.04). In women, the increase in AST and ALT with increasing the number of metabolic abnormalities was statistically significant (PAST=0.01; PALT<0.001). In men, ALT level had significantly positive correlation with waist circumference (r=0.14, P<0.05), serum TG (r=0.16, P<0.05) and fasting plasma glucose (r=0.17, P<0.01). In women, there was a significant correlation between AST level and serum TG (r=0.15, P<0.05). A significant positive and negative correlation were found respectively between serum ALT and AST/ALT ratio and waist circumference, serum TG and fasting blood glucose. Women in the 4th quartile of ALT were 4.43 fold at an increased risk for metabolic syndrome outcome when compared to those in the first quartile [OR (95% CI): 4.43 (1.69, 11.63)]. In women, with increasing the quartiles of ALT within normal limits, the percent of participants with metabolic syndrome also increased significantly (Ptrend=0.04). CONCLUSIONS Based on the results, the use of ALT and AST:ALT ratio as continuous biomarkers for early signaling of dysmetabolism especially in women could be encouraged.

Abstract
BACKGROUND Metabolic risk factors associated with non-alcoholic fatty liver disease (NAFLD) include Type 2 diabetes mellitus (T2DM), obesity and dyslipidaemia. Prevention or management of these risk factors with glycaemic control, weight reduction and low serum lipid levels respectively have been reported to reduce the risk of NAFLD or slow its progression. Since ultrasound (USS) is a safe and reliable method of identifying fatty changes in the liver, this study was done to determine the relationship between glycaemic control and ultrasound diagnosed NAFLD in T2DM. METHODOLOGY Demographic data, anthropometric measurements and laboratory tests including glycated haemoglobin (HbA1c), fasting blood glucose (FBG) and serum lipids of 80 T2DM subjects aged 40-80 years were taken. Their livers were evaluated using B-mode ultrasound, and the data obtained were statistically analysed using SPSS version 20. RESULTS Fifty-five of all participants (68.8%) were diagnosed with NAFLD sonographic grades 1, 2 and 3 made up of 13 (16.3%), 26 (32.5%) and 16 (20.0%), respectively while 25 (37.2%) had grade 0. The prevalence of NAFLD in T2DM varied significantly with BMI (p = 0.001) and glycaemic control (p = 0.048) while the USS grades of NAFLD varied significantly with age (p = 0.043) and BMI (p = 0.006). The independent strong predictors of NAFLD were overweight (r = 0.409, p = 0.012, OR = 6.626) and obesity (r = 0.411 p = 0.009, OR = 11.508), while poor glycaemic control (r = 0.270, p = 0.015, OR = 3.473) was a moderate independent predictor. CONCLUSION The prevalence of NAFLD increases with increasing BMI and HBA1c in T2DM, while its ultrasound grade varies with BMI. Overweight, obesity and poor glycaemic control are independent predictors of NAFLD.

Abstract
Objective Emerging studies have focused on the association between non-alcoholic fatty liver disease (NAFLD) and the risk of type 2 diabetes mellitus (T2DM). We aimed to investigate whether NAFLD diagnosed by ultrasonography could predict the risk of future T2DM in a Japanese middle-aged health check population. Methods We conducted a 10-year observational study in a health checkup population of middle-aged Japanese men and women at Hidaka Hospital from 2004 to 2013. We excluded cases with an alcohol intake exceeding 20 g/day and those with impaired glucose tolerance. The remaining 1,544 men and 864 women were classified into fatty liver and non-fatty liver groups based on the findings of abdominal ultrasonography. Both groups were followed for the development of diabetes. A multiple regression analysis was performed for each variable to predict the risk of future diabetes. Results The median age of the participants was 46.0 years at the entry, and the follow-up period was 10 years. The incidence of diabetes in the fatty liver group was 12.5% (29/232) in men and 26.3% (10/38) in women, whereas the incidence of diabetes in the non-fatty liver group was 2.5% (34/1,312) in men and 1.8% (15/826) in women. The relative risk of diabetes associated with fatty liver was 4.8 [95% confidence interval (CI) 3.0-7.8, p<0.0001] in men and 14.5 (95% CI 7.0-30.1, p<0.0001) in women. Conclusion NAFLD was a significant predictor for future diabetes in a Japanese middle-aged health check population, especially in women.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is being increasingly recognized as a cause of chronic liver disease. It has also been associated with devastating outcomes such as decompensated liver cirrhosis and hepatocellular carcinoma, as well as diabetes and metabolic syndrome. OBJECTIVES This study was conducted in order to assess liver fibrosis using Fibroscan, and to compare these results to the use of Fibrosis-4 (FIB-4) scores, AST platelet ratio index (APRI scores), and the AST/ALT ratios on NAFLD patients. PATIENTS AND METHODS A cross sectional study was conducted on NAFLD patients who underwent Fibroscan examinations between September 1, 2011 and June 30, 2014. Demographic data was collected, including sex, age, and nationality; serum alanine aminotransferase levels (ALT, 30 - 65 U/L), serum aspartate aminotransferase levels (AST, 15 - 37 U/L), and platelet counts (150 - 400 k/μL) were also determined. The stages of fibrosis (F0 1 - 6, F1 6.1 - 7, F2 7 - 9, F3 9.1 - 10.3, and F4 ≥ 10.4) were defined in kPa. For each patient, the AST/ALT ratio was also measured. The results of APRI and FIB-4 were compared with the Fibroscan fibrosis scores. RESULTS The results of 122 patients were analyzed, including 65 (53.3%) males with a mean age of 50.2 years (SD: 13.7; range: 18 - 86). The males were significantly younger than the females (48.7 years (SD: 16.03) versus 51.8 years (SD: 10.3 P = 0.05), respectively). The mean stiffness score was 12.02 (SD: 12.7) kPa. Forty-four patients (36%) had advanced fibrosis. The mean platelet and serum ALT levels were normal. There was a significant positive correlation between the Fibroscan results and the AST/ALT ratios, the APRI scores, and the FIB-4 results. Similarly, there was a significant positive correlation between age and fibrosis score, and a significant negative correlation between platelet count and stiffness score. CONCLUSIONS The data showed that more than one-third of the cohort exhibited advanced fibrosis, demonstrating the need for the early diagnosis and treatment of NAFLD. The use of Fibroscan with other serum markers has been shown to be helpful for the diagnosis of severe fibrosis.

Abstract
Aims/Introduction Non‐alcoholic fatty liver disease (NAFLD) is a metabolic disorder of the liver. The relationship between NAFLD and type 2 diabetes remains largely unknown. The aim of the present study was to determine the incidence of complications arising from the interaction between NAFLD and type 2 diabetes. Materials and Methods A total of 212 individuals with type 2 diabetes were included in the study. The presence of NAFLD was determined in individuals using abdominal ultrasonography for the diagnosis of fatty liver disease. Patients were divided into three groups based on the duration of diabetes and NAFLD diagnosis. Type 2 diabetes patients were placed in group A; patients with type 2 diabetes longer than NAFLD were placed in group B; and patients with NAFLD longer than type 2 diabetes were placed in group C. All individuals had undergone electrocardiogram, blood pressure measurements, and thorough medical history and physical examinations (Doppler ultrasound, electrophysiology, fundoscopy, cardiac computed tomography). Laboratory measurements included fasting blood glucose, glycated hemoglobin, oral glucose tolerance test, liver and renal function, lipid profile, and urinary albumin excretion. Results Compared with groups A and B, the patients of group C showed a higher prevalence of significant coronary artery disease and hypertension (P < 0.05). Compared with groups A and B, the patients of group C showed a lower prevalence of diabetic retinopathy and diabetic peripheral neuropathy (P < 0.05). There was no significant difference in the prevalence of diabetic nephropathy among the three groups (P > 0.05). Conclusions NAFLD combined with type 2 diabetes is associated with the presence of significant coronary artery disease and hypertension.

Abstract
OBJECTIVES It remains unclear whether non-alcoholic fatty liver disease (NAFLD) is a cause or a consequence of metabolic syndrome (MetS). We proposed a simplified Bayesian network (BN) and attempted to confirm their reciprocal causality. SETTING Bidirectional longitudinal cohorts (subcohorts A and B) were designed and followed up from 2005 to 2011 based on a large-scale health check-up in a Chinese population. PARTICIPANTS Subcohort A (from NAFLD to MetS, n=8426) included the participants with or without NAFLD at baseline to follow-up the incidence of MetS, while subcohort B (from MetS to NAFLD, n=16,110) included the participants with or without MetS at baseline to follow-up the incidence of NAFLD. RESULTS Incidence densities were 2.47 and 17.39 per 100 person-years in subcohorts A and B, respectively. Generalised estimating equation analyses demonstrated that NAFLD was a potential causal factor for MetS (relative risk, RR, 95% CI 5.23, 3.50 to 7.81), while MetS was also a factor for NAFLD (2.55, 2.23 to 2.92). A BN with 5 simplification strategies was used for the reciprocal causal inference. The BN's causal inference illustrated that the total effect of NAFLD on MetS (attributable risks, AR%) was 2.49%, while it was 19.92% for MetS on NAFLD. The total effect of NAFLD on MetS components was different, with dyslipidemia having the greatest (AR%, 10.15%), followed by obesity (7.63%), diabetes (3.90%) and hypertension (3.51%). Similar patterns were inferred for MetS components on NAFLD, with obesity having the greatest (16.37%) effect, followed by diabetes (10.85%), dyslipidemia (10.74%) and hypertension (7.36%). Furthermore, the most important causal pathway from NAFLD to MetS was that NAFLD led to elevated GGT, then to MetS components, while the dominant causal pathway from MetS to NAFLD began with dyslipidaemia. CONCLUSIONS The findings suggest a reciprocal causality between NAFLD and MetS, and the effect of MetS on NAFLD is significantly greater than that of NAFLD on MetS.

Prevalence of and predictive factors for nonalcoholic fatty liver disease in Sudanese individuals with type 2 diabetes: Is metabolic syndrome the culprit? Arab J Gastroenterol 2015; 16:54-8. [PMID: 26174761 DOI: 10.1016/j.ajg.2015.06.001] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2014] [Revised: 04/04/2015] [Accepted: 06/07/2015] [Indexed: 01/06/2023]
Abstract
BACKGROUND AND STUDY AIM Non-alcoholic fatty liver disease (NAFLD) is a common global chronic liver condition. The prevalence of NAFLD among individuals with type 2 diabetes is estimated to be as high as 75%. The aim of this study was to determine the prevalence of NAFLD among individuals with type 2 diabetes in Sudan. PATIENTS AND METHODS This was a cross-sectional hospital-based study, which was carried out at the Jabir Abu-Elizz diabetic centre in Khartoum; 167 outpatients with type 2 diabetes were enrolled. NAFLD was diagnosed based on ultrasound, following exclusion of significant alcohol intake and secondary causes of liver diseases. NAFLD was defined as hepatic steatosis in the absence of alcohol intake, medication, previous liver disease and negative results for the serological test for hepatitis B and C. Logistic regression analysis was used to determine independent risk factors for the development of NAFLD in individuals with type 2 diabetes. RESULTS The number of female subjects was 89 (53.3%), and most subjects (145, 86.8%) were between the ages of 40 and 70 years. The overall prevalence of fatty liver among individuals with type 2 diabetes was found to be 50.3%. Age, duration of diabetes, hypertension and HbA1c levels appeared to have no impact on the prevalence of NAFLD. The possible predictors of NAFLD were overweight, obesity, central obesity, high triglyceride level and low high-density lipoprotein cholesterol (HDL-c) level. A higher prevalence of NAFLD was observed in individuals with three components of the metabolic syndrome. CONCLUSION NAFLD was observed in half of the diabetic population, and its occurrence correlates positively with metabolic syndrome risk factors.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is emerging as the most common chronic liver condition in Western World and across the globe. NAFLD prevalence is estimated to be around one-third of the total population. There are no published data that project the future prevalence of NAFLD, but with an increase in epidemic of diabetes and obesity, it is possible to suggest an increase in a number of individuals with NAFLD. NAFLD is associated with insulin resistance and occurs with an increase in cluster of features of metabolic syndrome and type 2 diabetes. Therefore, it is important to exclude the possibility of diabetes in those individuals with evidence of fatty liver. The global diabetes epidemic continues to grow, and it is estimated that the number of people with diabetes will double by year 2030. NAFLD is also a risk factor for an increase in cardiovascular incidence independent of age, sex, low-density lipoprotein-cholesterol, smoking, and cluster of metabolic syndromes. It is expected that NAFLD will be an important challenge for health providers in the near future. Taking all these factors into consideration, we believe that increasing awareness of metabolic and cardiovascular impact of NAFLD among general practitioners and health authorities may decrease the serious consequences of late diagnosis of NAFLD. Importantly, the collaboration between medical specialties is vital in decreasing the impact of the epidemic of NAFLD. The focus of this review is in the role of primary care physician in diagnosis, treatment and prevention of NAFLD and patients education.

Abstract
Sonography is an effective, noninvasive, safe, and inexpensive technique for measurement of the liver. Measurements of the liver using 2D ultrasound aid in diagnosing and tracking liver disease and in surgical planning. Multiple studies have developed techniques to measure the adult liver using 2D ultrasound. The aim of this systematic literature review was to determine whether a correctly developed, reliable, and reproducible technique for measuring the liver using 2D ultrasound has been reported. Analysis of studies meeting the inclusion criteria showed that none of these studies has been rigorously undertaken in terms of sample size justification, validity, reliability, and/or statistical analysis.

Abstract
Background Some risk factors for atherosclerosis are followed by non-alcoholic fatty liver
disease (NAFLD). We wanted to use Multislice computed tomography (MSCT) as
technique for searching relationship between NAFLD and coronary artery disease
(CAD). Objective The relationship between NAFLD and CAD was investigated using MSCT. Methods A total of 372 individuals with or without cardiac symptoms who had undergone MSCT
angiography were included in the study. The patients were divided into two groups
according to the presence of NAFLD. Coronary artery segments were visually
evaluated via MSCT angiography. Based on the coronary artery stenosis degree,
those with no or minimal plaques were considered normal, whereas those who had
stenosis of less than 50% and at least one plaque were considered to have
non-obstructive coronary artery disease (non-obsCAD). The patients who had at
least one plaque and coronary artery stenosis of 50% or more were considered to
have obstructive coronary artery disease (obsCAD). NAFLD was determined according
to the MSCT protocol, using the liver density. Results According to the liver density, the number of patients with non-alcoholic fatty
liver disease (group 1) was 204 (149 males, 54.8%) and with normal liver (group 2)
was 168 (95 males, 45.2%). There were 50 (24.5%) non-obsCAD and 57 (27.9%) obsCAD
cases in Group 1, and 39 (23.2%) non-obsCAD and 23 (13.7%) obsCAD cases in Group
2. Conclusions The present study using MSCT demonstrated that the frequency of coronary artery
disease in patients with NAFDL was significantly higher than that of patients
without NAFDL.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder worldwide. Several lines of evidence have indicated a pathogenic role of insulin resistance, and a strong association with type 2 diabetes (T2MD) and metabolic syndrome. Importantly, NAFLD appears to enhance the risk for T2MD, as well as worsen glycemic control and cardiovascular disease in diabetic patients. In turn, T2MD may promote NAFLD progression. The opportunity to take into account NAFLD in T2MD prevention and care has stimulated several clinical studies in which antidiabetic drugs, such as metformin, thiazolidinediones, GLP-1 analogues and DPP-4 inhibitors have been evaluated in NAFLD patients. In this review, we provide an overview of preclinical and clinical evidences on the possible efficacy of antidiabetic drugs in NAFLD treatment. Overall, available data suggest that metformin has beneficial effects on body weight reduction and metabolic parameters, with uncertain effects on liver histology, while pioglitazone may improve liver histology. Few data, mostly preclinical, are available on DPP4 inhibitors and GLP-1 analogues. The heterogeneity of these studies and the small number of patients do not allow for firm conclusions about treatment guidelines, and further randomized, controlled studies are needed.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) can progress to advanced liver disease and non-liver-related diseases. To prevent NAFLD onset, clinicians must be able to easily identify high-risk NAFLD patients so that intervention can begin at an earlier stage. We sought to identify the predictive factors for NAFLD onset. METHODS In a community-based, longitudinal design, the records of 6,403 Japanese subjects were reviewed to identify those meeting the criteria for NAFLD onset. Univariate and multivariate logistic regression analyses were used to identify predictive factors for NAFLD onset. The accuracy of different models was evaluated according to their areas under the receiver operating characteristic curves. Comparative risk analysis was performed using the Kaplan-Meier method. RESULTS Multivariate analysis of 400 subjects who met the criteria for the onset of NAFLD during the observation period confirmed that body mass index (BMI) at baseline was the most useful predictive factor for NAFLD onset in both sexes. Cutoff levels of BMI for NAFLD onset were estimated at 23 kg/m2 for men and 22.2 kg/m2 for women. The cumulative onset rate of NAFLD was significantly higher in the high BMI group than in the low BMI group in both sexes (P < 0.001). CONCLUSION BMI was confirmed as the most useful predictive factor for NAFLD onset in both sexes; its cutoff levels were similar to those recommended by the World Health Organization for helping to prevent metabolic disease. An accurate BMI cutoff level will enable clinicians to identify subjects at risk for NAFLD onset.

Abstract
OBJECTIVES There were many studies for the clinical association between non alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS). However, while most of studies have focused on the unilateral effects of MetS on NAFLD, studies for reverse association were comparatively rare. Therefore, we carried out a prospective cohort study to evaluate the longitudinal effects of NAFLD on the development of MetS according to the degree of NAFLD. PATIENTS AND METHODS A total of 46,874 men, who had participated in a medical health check-up program in 2005, were enrolled in this study. Out of them, a Mets-free cohort of 11,926 without excluding conditions was followed up until 2010. All participants were classified into 3 groups by their NAFLD status (normal, mild, moderate to severe). The baseline values of metabolic components and the development rates of MetS were compared according to the degree of NAFLD. Cox proportional hazards model was used to measure the hazard ratios (HRs) for MetS according to the degree of NAFLD. RESULTS During 41,912.1 person-years of follow-up, 1861 incident cases of MetS developed between 2006 and 2010. Even after adjusting for multiple covariates, the HRs (95% CI) for MetS were higher in the mild group (1.49; 1.30-1.70) and moderate to severe group (2.00; 1.46-2.73) compared to normal group, respectively (P for trend <0.001). These associations were apparent in the clinically relevant subgroup analyses. CONCLUSIONS NAFLD was independent risk factor for MetS during the 5-yr follow-up period.

Abstract
BACKGROUND The estimated prevalence of nonalcoholic fatty liver disease (NAFLD) in Saudi Arabia is 7% to 10%. Despite the high prevalence of risk factors including diabetes, obesity, and hyperlipidemia, no recent epidemiological studies have measured the disease burden. We aimed to determine the characteristics of Saudi NAFLD patients attending a university hospital, and study factors affecting alanine aminotransferase (ALT) levels. DESIGN AND SETTING A prospective study among patients referred for ultrasonography in King Khalid University Hospital in Riyadh, Saudi Arabia from February to May 2009. PATIENTS AND METHODS NAFLD was defined as an appearance of fatty liver on routine abdominal ultrasound in the absence of coexisting liver disease and alcohol consumption. Patients were classified into normal and high ALT (ALT >60 U/L) level groups for analysis. RESULTS The prevalence of NAFLD was 16.6% (218/1312). Patients with normal ALT had the mean (SD) age of 45.9 (10.6) years and the mean body mass index of 34.5 (7.9) kg/m2. Forty percent of the 151 patients with normal ALT had diabetes, 66.2% were obese, and 29.1% had hypertension. Forty-three patients (23%) had high ALT levels. These patients had significantly lower age (P=.003) and fasting blood sugar (P=.03) than the normal ALT group. Non-diabetic patients (odds ratio 0.30, 95% CI 0.1-0.8), men (female OR 0.23, 95% CI 0.1-0.5), lower cholesterol (P=.001), high-density lipoprotein (P=.006), and low-density lipoprotein (P=.008) levels were more likely to be observed among patients with high ALT levels. In a multivariate analysis, younger age (OR 0.96, 95% CI 0.93-0.99), being male (OR 0.23, 95% CI 0.09-0.57), and a lower cholesterol level (OR 0.55, 95% CI 0.37-0.82) were significant predictors of high ALT levels. CONCLUSION Based on the high prevalence of obesity and diabetes, the prevalence of NAFLD will continue to be high, unless awareness is inculcated among the local population.

Abstract
AIM: To clarify the efficiency of the criterion of metabolic syndrome to detecting non-alcoholic fatty liver disease (NAFLD).
METHODS: Authors performed a cross-sectional study involving participants of a medical health checkup program including abdominal ultrasonography. This study involved 11 714 apparently healthy Japanese men and women, 18 to 83 years of age. NAFLD was defined by abdominal ultrasonography without an alcohol intake of more than 20 g/d, known liver disease, or current use of medication. The revised criteria of the National Cholesterol Education Program Adult Treatment Panel III were used to characterize the metabolic syndrome.
RESULTS: NAFLD was detected in 32.2% (95% CI: 31.0%-33.5%) of men (n = 1874 of 5811) and in 8.7% (95% CI: 8.0%-9.5%) of women (n = 514 of 5903). Among obese people, the prevalence of NAFLD was as high as 67.3% (95% CI: 64.8%-69.7%) in men and 45.8% (95% CI: 41.7%-50.0%) in women. Although NAFLD was thought of as being the liver phenotype of metabolic syndrome, the prevalence of the metabolic syndrome among subjects with NAFLD was low both in men and women. 66.8% of men and 70.4% of women with NAFLD were not diagnosed with the metabolic syndrome. 48.2% of men with NAFLD and 49.8% of women with NAFLD weren’t overweight [body mass index (BMI) ≥ 25 kg/m2]. In the same way, 68.6% of men with NAFLD and 37.9% of women with NAFLD weren’t satisfied with abdominal classification (≥ 90 cm for men and ≥ 80 cm for women). Next, authors defined it as positive at screening for NAFLD when participants satisfied at least one criterion of metabolic syndrome. The sensitivity of the definition “at least 1 criterion” was as good as 84.8% in men and 86.6% in women. Separating subjects by BMI, the sensitivity was higher in obese men and women than in non-obese men and women (92.3% vs 76.8% in men, 96.1% vs 77.0% in women, respectively).
CONCLUSION: Authors could determine NAFLD effectively in epidemiological study by modifying the usage of the criteria for metabolic syndrome.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is prevalent in people with the metabolic syndrome and type 2 diabetes and is present in up to one-third of the general population. Evidence is now accumulating that NAFLD is associated with obesity and diabetes and may serve as a predictor of cardiovascular disease (CVD). The possible mechanisms linking NAFLD and CVD include inflammation and oxidative stress, hyperlipidaemia, insulin resistance, and direct impact of NAFLD on coronary arteries and left ventricular dysfunction. In addition, several studies suggest that NAFLD is associated with high risk of CVD and atherosclerosis such as carotid artery wall thickness and lower endothelial flow-mediated vasodilation independently of classical risk factors and components of the metabolic syndrome. It is not yet clear how treatment of NAFLD will modulate the risk of CVD. Furthermore, studies are urgently needed to establish (i) the pathophysiology of CVD with NAFLD and (ii) the benefit of early diagnosis and treatment of CVD in patients with NAFLD. In the absence of biochemical markers, it is crucial that screening and surveillance strategies are adopted in clinical practice in the growing number of patients with NAFLD and at risk of developing CVD. Importantly, the current evidence suggest that statins are safe and effective treatment for CVD in individuals with NAFLD.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of hepatic dysfunction encountered in general practice. A large proportion of individuals with type 2 diabetes and the metabolic syndrome develop NAFLD. NAFLD is associated with severe insulin resistance and increased risk of cardiovascular disease and can progress to non-alcoholic steato-hepatitis, liver cirrhosis and cancer. Currently the only known effective treatments for NAFLD are lifestyle changes including stable weight loss and a diet low in calories. General practitioners will increasingly play a key role in dealing with this evolving but serious epidemic of NAFLD and associated metabolic complications. However, success will depend on the appropriate systems and mechanisms being in place in primary care and the proper motivation, support and education of the patient. This review provides the primary care physician with: (a) a step-by step guide of how to identify NAFLD, (b) information to exclude common other causes of liver fat accumulation and (c) additional insight into relationships between NAFLD and other conditions such as obesity, cardiovascular disease and type 2 diabetes.

Abstract
OBJECTIVES The significance of nonalcoholic fatty liver disease (NAFLD) among patients with diabetes is unknown. We sought to determine whether a diagnosis of NAFLD influenced mortality among a community-based cohort of patients with type II diabetes mellitus. METHODS A total of 337 residents of Olmsted County, Minnesota with diabetes mellitus diagnosed between 1980 and 2000 were identified using the Rochester Epidemiology Project and the Mayo Laboratory Information System, and followed for 10.9 + or - 5.2 years (range 0.1-25). Survival was analyzed using Cox proportional hazards modeling, with NAFLD treated as a time-dependent covariate. RESULTS Among the 337 residents, 116 were diagnosed with NAFLD 0.9 + or - 4.6 years after diabetes diagnosis. Patients with NAFLD were younger, and more likely to be female and obese. Overall, 99/337 (29%) patients died. In multivariate analysis to adjust for confounders, overall mortality was significantly associated with a diagnosis of NAFLD (hazard ratio (HR) 2.2; 95% confidence interval (CI) 1.1, 4.2; P=0.03), presence of ischemic heart disease (HR 2.3; 95% CI 1.2, 4.4), and duration of diabetes (HR per 1 year, 1.1; 95% CI 1.03, 1.2). The most common causes of death in the NAFLD cohort were malignancy (33% of deaths), liver-related complications (19% of deaths), and ischemic heart disease (19% of deaths). In adjusted multivariate models, NAFLD was borderline associated with an increased risk of dying from malignancy (HR 2.3; 95% CI 0.9, 5.9; P=0.09) and not from cardiovascular disease (HR 0.9; 95% CI 0.3, 2.4; P=0.81). CONCLUSIONS The diagnosis of NAFLD is associated with an increased risk of overall death among patients with diabetes mellitus.

Abstract
Metabolic syndrome (MS) is a core set of disorders, including abdominal obesity, dyslipidemia, hypertension and hypertriglyceridemia that together predict the development of diabetes type 2 and cardiovascular disease. This study investigated the relationship between liver enzyme levels and high-sensitivity C-reactive protein (hs-CRP) in subjects with and without MS. Alanine-aminotransferase (ALAT), aspartate-aminotransferase (ASAT), γ-glutamyl transferase (GGT) and hs-CRP were measured in 510 subjects, aged 40 to 65 years old. Patients were selected from 1007 subjects from the Research Program for Cardiovascular Disease Risk Factors in Talca, Chile. Results showed that women with MS presented higher liver enzyme levels than those who did not have MS. This was not observed in male patients for the enzymes ALAT and ASAT. However, GGT and hs-PCR levels were higher in male and female patients with MS than in those without MS. In conclusion, it is important to search for the presence of MS when diagnosing fatty liver. Moreover, the presence of liver disease in patients with MS should be further investigated.

Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease (NAFLD) is closely associated with insulin resistance and metabolic syndrome. Prevalence of NAFLD increases greatly in patients with type 2 diabetes mellitus (T2DM), and it may also increase cardiovascular disease mortality and morbidity. The aim of our study was to investigate the prevalence of NAFLD in T2DM population and to compare the prevalence of coronary heart disease (CHD) and its risk factors between diabetic patients with and without NAFLD in a Chinese population. METHODS A cross-sectional survey was conducted among 560 cases of in-patient T2DM patients from January 2002 to January 2009 in southern China. Patients were divided into two groups (NAFLD and non-NAFLD) and underwent clinical examination, anthropometry, laboratory tests and routine liver ultrasonography. RESULTS Prevalence of NAFLD was 75.18% (421 cases) among all participants, and 285 cases (67.70%) had normal liver function and no symptoms. NAFLD group had higher body mass index (BMI), waist/hip circumference ratio (WHR), alanine aminotransferase (ALT), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) levels than those without NAFLD (p<0.01). Moreover, the prevalence of CHD was also higher in the NAFLD group (p<0.01), especially in those male patients with elevated plasma ALT. CONCLUSIONS NAFLD is a common condition among T2DM patients. Its occurrence may be related to sex, age, abdominal obesity, dyslipidemia metabolism, etc. and it is associated with a higher prevalence of CHD. Plasma ALT levels may act as a marker.

Abstract
NAFLD (non-alcoholic fatty liver disease) refers to a wide spectrum of liver damage, ranging from simple steatosis to NASH (non-alcoholic steatohepatitis), advanced fibrosis and cirrhosis. NAFLD is strongly associated with insulin resistance and is defined by accumulation of liver fat >5% per liver weight in the presence of <10 g of daily alcohol consumption. The exact prevalence of NAFLD is uncertain because of the absence of simple non-invasive diagnostic tests to facilitate an estimate of prevalence. In certain subgroups of patients, such as those with Type 2 diabetes, the prevalence of NAFLD, defined by ultrasound, may be as high as 70%. NASH is an important subgroup within the spectrum of NAFLD that progresses over time with worsening fibrosis and cirrhosis, and is associated with increased risk for cardiovascular disease. It is, therefore, important to understand the pathogenesis of NASH and, in particular, to develop strategies for interventions to treat this condition. Currently, the 'gold standard' for the diagnosis of NASH is liver biopsy, and the need to undertake a biopsy has impeded research in subjects in this field. Limited results suggest that the prevalence of NASH could be as high as 11% in the general population, suggesting there is a worsening future public health problem in this field of medicine. With a burgeoning epidemic of diabetes in an aging population, it is likely that the prevalence of NASH will continue to increase over time as both factors are important risk factors for liver fibrosis. The purpose of this review is to: (i) briefly discuss the epidemiology of NAFLD to describe the magnitude of the future potential public health problem; and (ii) to discuss extra- and intra-hepatic mechanisms contributing to the pathogenesis of NAFLD, a better understanding of which may help in the development of novel treatments for this condition.

Abstract
Our aim was to study whether visceral adiposity is a predictor of diabetic fatty liver in Korean type 2 diabetes mellitus. In this study, abdominal ultrasonography was used to assess the presence of fatty liver in 1,898 patients with type 2 diabetes. We measured visceral fat thickness by high-resolutional ultrasonography and insulin resistance by Kitt. Half of the cohort had a fatty liver (50.2%). High visceral fat thickness had the highest odds ratio for developing fatty liver in both sexes (odds ratio [S.D]: 3.14 [2.24-4.69], p<0.00 in male, 2.84 [2.04-3.93], p<0.00 in female). In addition, visceral fat thickness of 42.45 and 37.7 mm in men and women, respectively, were chosen as the discriminating value to predict the presence of fatty liver with a sensitivity of 71% and 73% and a specificity of 70% and 70% in men and women, respectively. The area under the receiver-operating characteristics curve was 0.759 in men and 0.764 in women. Therefore we could conclude that the degree of visceral adiposity predicts the presence of fatty liver type 2 diabetes mellitus, whether centrally obese or not, suggesting that hepatic fat accumulation in a diabetic fatty liver may be influenced by visceral fat accumulation regardless of waist circumference.

Abstract
OBJECTIVE To determine the association between nonalcoholic fatty liver disease and the risk for development of diabetes. RESEARCH DESIGN AND METHODS We conducted an observational cohort study in male workers > or = 40 years old in a Japanese company from 1997 to 2005. We excluded workers with alcohol intake > or = 20 g/day and those with impaired glucose tolerance by a 75-g oral glucose tolerance test. The remaining 3,189 workers were classified into fatty liver (FL) and non-FL group based on the findings of abdominal ultrasonography. Both groups were followed for the development of diabetes. Hazard ratio (HR) was determined in Cox proportional hazard analysis. A nested case-control study was conducted to determine the odds ratio (OR). RESULTS The average age of participants was 48.0 years at the entry, and the average follow-up period was 4.0 years. The incidence of diabetes in the FL group was 2,073 per 100,000 person-years (65 cases), whereas 452 per 100,000 person-years (44 cases) in the non-FL group. The age- and BMI-adjusted HR of diabetes associated with FL was 5.5 (95% CI 3.6-8.5, P < 0.001). In the nested case-control analysis, the OR adjusted for age and BMI was 4.6 (3.0-6.9, P < 0.001). CONCLUSIONS Nonalcoholic fatty liver disease significantly increases the risk of diabetes in middle-aged Japanese men.

Abstract
Nonalcoholic fatty liver disease (NAFLD) refers to a spectrum of liver damage ranging from simple steatosis to nonalcoholic steatohepatitis, advanced fibrosis, and rarely, progression to cirrhosis. The pathogenesis of NAFLD is thought to be related to insulin resistance and oxidant stress. Truncal obesity, dyslipidema, hypertension, and hyperglycemia are strongly associated with NAFLD; therefore, management of NAFLD entails identification and treatment of metabolic risk factors, improving insulin sensitivity, and increasing antioxidant defenses in the liver. This article briefly summarizes advances in our understanding of the relationship between NAFLD and the insulin resistance (metabolic) syndrome, its prevalence, natural history, and treatment.

Abstract
AIM: To clarify whether nonalcoholic fatty liver disease (NAFLD) increases the risk of cardiovascular disease.
METHODS: We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program. NAFLD was diagnosed by abdominal ultrasonography. The metabolic syndrome (MS) was defined according to the modified National Cholesterol Education Program (NCEP) ATP III criteria. Five years after the baseline evaluations, the incidence of cardiovascular disease was assessed by a self-administered questionnaire.
RESULTS: Among 1221 participants available for outcome analyses, the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline (5 coronary heart disease, 6 ischemic stroke, and 1 cerebral hemorrhage) than 990 subjects without NAFLD (3 coronary heart disease, 6 ischemic stroke, and 1 cerebral hemorrhage). Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors (odds ratio 4.12, 95% CI, 1.58 to 10.75, P = 0.004). MS was also independently associated with cardiovascular events. But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.
CONCLUSION: Although both of them were predictors of cardiovascular disease, NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model. NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS.

Abstract
CONTEXT Insulin resistance is an almost universal finding in nonalcoholic fatty liver disease (NAFLD). This review outlines the evidence linking insulin resistance and NAFLD, explores whether liver fat is a cause or consequence of insulin resistance, and reviews the current evidence for treatment of NAFLD. EVIDENCE ACQUISITION Evidence from epidemiological, experimental, and clinical research studies investigating NAFLD and insulin resistance was reviewed. EVIDENCE SYNTHESIS Insulin resistance in NAFLD is characterized by reductions in whole-body, hepatic, and adipose tissue insulin sensitivity. The mechanisms underlying the accumulation of fat in the liver may include excess dietary fat, increased delivery of free fatty acids to the liver, inadequate fatty acid oxidation, and increased de novo lipogenesis. Insulin resistance may enhance hepatic fat accumulation by increasing free fatty acid delivery and by the effect of hyperinsulinemia to stimulate anabolic processes. The impact of weight loss, metformin, and thiazolidinediones, all treatments aimed at improving insulin sensitivity, as well as other agents such as vitamin E, have been evaluated in patients with NAFLD and have shown some benefit. However, most intervention studies have been small and uncontrolled. CONCLUSION Insulin resistance is a major feature of NAFLD that, in some patients, can progress to steatohepatitis. Treatments aimed at reducing insulin resistance have had some success, but larger placebo-controlled studies are needed to fully establish the efficacy of these interventions and possibly others in reducing the deleterious effects of fat accumulation in the liver.
