Nonalcoholic fatty liver disease (NAFLD), an escalating health problem worldwide, covers a spectrum of pathologies characterized by fatty accumulation in hepatocytes in early stages, with potential progression to liver inflammation, fibrosis, and failure. A close, yet poorly understood link exists between NAFLD and dyslipidemia, a constellation of abnormalities in plasma lipoproteins including triglyceride-rich very low density lipoproteins. Apolipoproteins are a group of primarily liver-derived proteins found in serum lipoproteins; they not only play an extracellular role in lipid transport between vital organs through circulation, but also play an important intracellular role in hepatic lipoprotein assembly and secretion. The liver functions as the central hub for lipoprotein metabolism, as it dictates lipoprotein production and to a significant extent modulates lipoprotein clearance. Lipoprotein metabolism is an integral component of hepatocellular lipid homeostasis and is implicated in the pathogenesis, potential diagnosis, and treatment of NAFLD.

Nonalcoholic fatty liver disease (NAFLD) is the most common, chronic liver disease worldwide. Within this spectrum, steatosis alone is apparently benign, while nonalcoholic steatohepatitis may progress to cirrhosis and hepatocellular carcinoma. NAFLD is strongly associated with obesity, dyslipidemia, type 2 diabetes mellitus, and cardiovascular disease. The pathogenesis of hepatic steatosis is not clearly known, but its main characteristics are considered insulin resistance, mitochondrial dysfunction, increased free fatty acids reflux from adipose tissue to the liver, hepatocyte lipotoxicity, stimulation of chronic necroinflammation, and fibrogenic response. With recent advances in technology, advanced imaging techniques provide important information for diagnosis. There is a significant research effort in developing noninvasive monitoring of disease progression to fibrosis and response to therapy with potential novel biomarkers, in order to facilitate diagnosis for the detection of advanced cirrhosis and to minimize the need of liver biopsy. The identification of NAFLD should be sought as part of the routine assessment of type 2 diabetics, as sought the microvascular complications and cardiovascular disease, because it is essential for the early diagnosis and proper intervention. Diet, exercise training, and weight loss provide significant clinical benefits and must be considered of first line for treating NAFLD.

Non-alcoholic fatty liver disease is marked by hepatic fat accumulation not due to alcohol abuse. Several studies have demonstrated that NAFLD is associated with insulin resistance leading to a resistance in the antilipolytic effect of insulin in the adipose tissue with an increase of free fatty acids (FFAs). The increase of FFAs induces mitochondrial dysfunction and development of lipotoxicity. Moreover, in subjects with NAFLD, ectopic fat also accumulates as cardiac and pancreatic fat. In this review we analyzed the mechanisms that relate NAFLD with metabolic syndrome and dyslipidemia and its association with the development and progression of cardiovascular disease.

Nonalcoholic fatty liver disease (NAFLD) is increasingly recognized as an important public health problem nowadays. NAFLD encompass a variety of liver pathologies including simple steatosis, NASH, fibrosis, cirrhosis and finally cancer. It is associated with obesity, metabolic syndrome, dyslipidaemia, Insulin resistance (IR) and type 2 diabetes. It is the most common chronic liver disease in USA and considered to be increasing in Asia Pacific region including South Asia however there is no community based study from Pakistan. Customarily NAFLD had been regarded as a benign disease; however clinical as well as epidemiological studies had contradicted this belief because approximately 20% of the patients with NAFLD had NASH which has propensity to develop cirrhosis and ultimately to HCC. The diagnosis of NAFLD is made most of the times incidentally on abdominal imaging which is done for other purposes. Despite its prevalence, treatment options are very limited. However modification of risk factors such as dyslipidemia, diabetes control and weight reduction does help in NAFLD. Fatty liver results due to lack of physical activity; hence foremost step to manage such patients would be to develop the healthy life style. We need population based studies in our country so that we can protect our population from a new epidemic.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the pediatric population. Increased recognition of this form of liver disease parallels the dramatic rise in childhood and adolescent obesity over the past 2 decades. Like adults, most children with NAFLD are obese, and comorbidities include insulin resistance, hypertension, and dyslipidemia. Unfortunately, pediatric NAFLD is not always a benign condition, with some children progressing to hepatic fibrosis and even cirrhosis in severe cases. The etiology of nonalcoholic steatohepatitis is not yet fully understood; however, hepatic steatosis in the context of insulin resistance and increased oxidative stress may lead to progressive disease. Although physical examination, laboratory evaluation, and radiographic findings provide clues to the potential presence of fatty liver disease, liver biopsy remains the gold standard for diagnosis. Lifestyle modification, including slow and steady weight loss, improved dietary habits, and increased daily, aerobic physical activity, remains the first-line approach in treating pediatric fatty liver disease. Antioxidant pharmacologic therapy such as use of vitamin E has shown some benefit in patients with biopsy-proven steatohepatitis. Nutrition plays an essential role not only in the development of fatty liver disease but also potentially in the treatment and prevention of progression to more severe disease.

Nonalcoholic fatty liver disease (NAFLD) is the most frequent cause of liver disease in the United States and is associated with an increased risk of cardiovascular disease (CVD) and cardiovascular (CV) mortality, independent of traditional cardiovascular risk factors. CVD is one of the most common causes of death among individuals with NAFLD and management of NAFLD must extend beyond liver disease to include CVD risk modification. Clinicians should assess CVD risk with the Framingham Risk Score and screen for CVD risk factors including dyslipidemia, diabetes mellitus, hypertension, tobacco use, and the metabolic syndrome. CVD risk factors, particularly dyslipidemia, require aggressive medical management to reduce the high risk of CVD events and death in individuals with NAFLD.

Non-alcoholic steatohepatitis (NASH), which involves hepatic inflammation and fibrosis, is associated with liver carcinogenesis. The activation of the renin-angiotensin system (RAS), which plays a key role in blood pressure regulation, promotes hepatic fibrogenesis. In this study, we investigated the effects of (-)-epigallocatechin-3-gallate (EGCG), a major component of green tea catechins, on the development of glutathione S-transferase placental form (GST-P)-positive (GST-P(+)) foci, a hepatic preneoplastic lesion, in SHRSP.Z-Lepr(fa)/IzmDmcr (SHRSP-ZF) obese and hypertensive rats. Male 7-week-old SHRSP-ZF rats and control non-obese and normotensive WKY rats were fed a high fat diet and received intraperitoneal injections of carbon tetrachloride twice a week for 8weeks. The rats were also provided tap water containing 0.1% EGCG during the experiment. SHRSP-ZF rats presented with obesity, insulin resistance, dyslipidemia, an imbalance of adipokines in the serum, and hepatic steatosis. The development of GST-P(+) foci and liver fibrosis was markedly accelerated in SHRSP-ZF rats compared to that in control rats. Additionally, in SHRSP-ZF rats, RAS was activated and inflammation and oxidative stress were induced. Administration of EGCG, however, inhibited the development of hepatic premalignant lesions by improving liver fibrosis, inhibiting RAS activation, and attenuating inflammation and oxidative stress in SHRSP-ZF rats. In conclusion, obese and hypertensive SHRSP-ZF rats treated with a high fat diet and carbon tetrachloride displayed the histopathological and pathophysiological characteristics of NASH and developed GST-P(+) foci hepatic premalignant lesions, suggesting the model might be useful for the evaluation of NASH-related liver tumorigenesis. EGCG might also be able to prevent NASH-related liver fibrosis and tumorigenesis.

The prevalence of overweight and obesity in childhood is a major public health concern. According to the obesity trend, the prevalence of pediatric nonalcoholic fatty liver disease (NAFLD) is also increasing. Nonalcoholic fatty liver disease is characterized by a spectrum of hepatic lesions (i.e., steatosis, ballooning, necroinflammation and fibrosis) that can progress to cirrhosis, hepatocellular carcinoma and liver failure with the consequent need for liver transplantation. Pediatric NAFLD is typically of primary origin and it is strongly associated with several features of the metabolic syndrome such as obesity, insulin resistance, dyslipidemia and Type 2 diabetes. The evaluated article reports the prospective relationship between dietary patterns at age 14 years and the presence of NAFLD at age 17 years. A total of 995 adolescents completed a food frequency questionnaire at 14 years and had liver ultrasound at 17 years. Prospective associations between the dietary pattern scores and the risk of NAFLD were analyzed using multiple logistic regression analyses. Nonalcoholic fatty liver disease was present in 15.2% of adolescents. A healthy dietary pattern at 14 years appeared protective against NAFLD at 17 years in centrally obese adolescents. On the contrary, a western dietary pattern at 14 years in this cohort was associated with an increased risk of NAFLD at 17 years, particularly in obese adolescents.

Nonalcoholic fatty liver disease (NAFLD) is an emerging global health concern. It is the most common form of chronic liver disease in Western countries, affecting both adults and children. NAFLD encompasses a broad spectrum of fatty liver disease, ranging from simple steatosis (NAFL) to nonalcoholic steatohepatitis (NASH), and is strongly associated with obesity, insulin resistance, and dyslipidemia. First-line therapy for NAFLD includes weight loss achieved through diet and physical activity. However, there is a lack of evidenced-based dietary recommendations. The American Diabetes Association's (ADA) recommendations that aim to reduce the risk of diabetes and cardiovascular disease may also be applicable to the NAFLD population. The objectives of this review are to: (1) provide an overview of NAFLD in the context of insulin resistance, and (2) provide a rationale for applying relevant aspects of the ADA recommendations to the nutritional management of NAFLD.

Total 33 obese patients were studied to determine correlation in between liver fat content with dyslipidemia and insulin resistance. Liver and spleen attenuation measurements were taken with three regions of interests (ROIs) from the liver and two ROIs from the spleen. Hepatic attenuation indices were measured as follows: (1) Hepatic parenchymal attenuation (CTLP); (2) liver to spleen attenuation ratio (LSratio); and (3) difference between hepatic and splenic attenuation (LSdif). Bivariate correlation analysis showed moderate but statistically significant negative correlation between CTLP, LSratio, and LSdif with body mass index, triglyceride, fasting plasma sugar, fasting plasma insulin, homeostasis model assessment-insulin resistance (HOMA IR), 2 h oral glucose tolerance test (OGTT), and statistically significant positive correlation with high density lipoprotein. Nonalcoholic fatty liver disease (NAFLD) is closely associated with features of the metabolic syndrome. The amount of intrahepatic fat closely correlates with the number of metabolic syndrome features. The values of CTLP, LSratio, and LSdif demonstrate strong inverse correlations with degree of steatosis.
