Filter by:Non Alcohlic Fatty Liver (NAFLD) is a spectrum of diseases that ranges from accumulation of fat in the liver (Hepatosteatosis) that may be accompanied by inflammation (Steatohepatitis) to necrosis, fibrosis and even cirrhosis resembling alcoholic hepatitis in the absence of alcoholic abuse (Pardee et al., 2012). It has been estimated that the global prevalence of NAFLD is as high as one billion. In the United States, NAFLD is estimated to be the most common cause of chronic liver disease, affecting between 80 and 100 million individuals, among whom nearly 25% progress to NASH (Loomba et al., 2013). In general, the prevalence of NAFLD has increased over the last 20 years. The Middle East and South America have the highest NAFLD prevalence at 31% and 32% respectively with the lowest prevalence in Africa at 13.5% (Younossi et al., 2016). Liver biopsy (LB) is still the standard test of NAFLD diagnosis and the presence of early liver fibrosis. However, histologic lesions are not evenly distributed throughout the liver. A sampling error is the biggest limitation in the diagnosis of NAFLD by LB with inflammatory lesions and ballooning degeneration potentially resulting in misdiagnoses and staging inaccuracies (Lee et al., 2016). To overcome these limitations, several non-invasive markers have been used instead of liver biopsy. These methods are either laboratory markers or imaging modalities. Controlled attenuation parameter (CAP) is a new technology based on the principle of the ultrasonic attenuation of transient elastography depending on the viscosity [fat] of the medium [liver] and the distance of propagation of the ultrasonic signals into the liver, providing a useful method for the quantitative detection of liver fat content and is considered a better assessment method for hepatic steatosis. Compared with ultrasound, this technology improves the sensitivity and specificity for the diagnosis of fatty liver and can be used for universal screening, diagnosis, and follow-up in NAFLD patients (Sasso et al., 2016). NAFLD is known to be closely associated with metabolic conditions, including insulin resistance, abdominal obesity, dyslipidaemia and type 2 diabetes, and is thus regarded as the hepatic manifestation of the metabolic syndrome (Ballestri., 2016). In recent epidemiological studies, NAFLD was shown to be connected with diseases that are usually not dependent on obesity, such as sarcopenia and osteoporosis (Poggiogalle et al., 2017). Osteoporosis is becoming a public health problem all over the world. Disability resulting from low-energy fractures, e.g: hip or vertebral fractures, is the major concern for early detection and treatment. It is estimated that osteoporosis affects 200 million women worldwide (Kanis et al., 2007). Liver is the source of many proteins and is the regulator of several pathways involving bone metabolism; one of the most well-known of all is vitamin D metabolism pathway. Considering the role of liver in bone metabolism, the association between NAFLD and bone abnormalities is not surprising especially with substantial supporting evidences in recent years (Eshraghian et al., 2017). Besides its role in the calcium and bone metabolism, vitamin D may also exert pleiotropic effects in many tissues. NAFLD patients were reported to have a marked reduction in serum 25(OH) vitamin D when compared with controls (Yilmaz et al., 2011). In adults, bone is constantly being remodeled, first being broken down (bone resorption) and then being rebuilt (bone formation). The resorption and reformation of bone is important for repair of microfractures and to allow modification of structure in response to stress and other biomechanical forces. Bone formation is normally tightly coupled to bone resorption, so that bone mass does not change. Bone diseases occur when formation and resorption are uncoupled. Several assays are available that measure bone turnover markers (BTMs). These assays measure collagen breakdown products and other molecules released from osteoclasts and osteoblasts during the process of bone resorption and formation. Markers that are specific to bone formation include bone-specific alkaline phosphatase (BSAP), osteocalcin, and N-terminal propeptide of type I procollagen (PINP); markers specific to bone resorption include N-terminal telopeptide of type I collagen (NTX), C-terminal telopeptide of type I collagen (CTX), and pyridinoline cross-links (Rosen et al., 2019).
Significant weight reduction, achieved by low-calorie diet (LCD), will mobilise ectopic fat (visceral and particularly liver fat), improving insulin sensitivity and other metabolic syndrome components, with secondary beneficial effects on cardiac structure and function. This CALIBRATE study (metabolic, multi-organ and effects of low-calorie diet in younger obese patients with pre-diabetes) will compare the effects of a safe and effective 12-month weight management intervention, initially using a low-calorie, liquid replacement diet for 12 weeks, anticipating at least 10% reduction in body weight. The investigators will examine how much the weight loss improves the metabolic abnormalities that precede type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease (CVD). This study will compare the effects of a safe and effective 12-month weight management intervention, initially using a low-calorie, liquid replacement diet for 12 weeks, followed by a weight maintenance phase. The investigators will examine how much the weight loss improves the metabolic and neuropathic abnormalities that precede and accompany type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease. In an additional optional sub-study, the investigators will additionally assess how the weight loss impacts upon appetite regulation within the brain with functional MRI (fMRI).
Obesity is associated with a variety of co-morbidities. Children with obesity are more likely to have risk factors associated with cardiovascular diseases (CVD) and CVD risk markers (e.g. hypertension, elevated serum cholesterol, and type 2 diabetes mellitus), but also with organ specific pathologies such as a non-alcoholic fatty liver disease (NAFLD). A recent meta-analysis has shown that the prevalence of NAFLD in obese pediatric populations is approximately 35%, compared to approximately 8% in general pediatric population, making it a very important health threat in these populations. Successful pharmacological interventions to treat or prevent NASH are not yet available and so far only weight loss has clear benefits. However, it is well known that sustained weight-loss is difficult to achieve on the longer-term. The investigators recently demonstrated in mice that plant sterol and stanol ester consumption inhibited the development of liver inflammation. Moreover, Javanmardi et al. recently demonstrated in a population of adult NAFLD patients, that plasma concentrations of Alanine Transaminase (ALT) were reduced after daily plant sterol consumption (1.6 g/d) for 6 weeks. In this study, the investigators propose to evaluate the effect of consuming soft chews enriched with plant stanol esters (3 grams/day) on ALT concentrations in children with overweight or (morbid) obesity who are at risk of developing NAFLD, in a randomized, placebo-controlled, double blinded study with an intervention period and follow-up period of 6 months. 52 overweight and obese children with elevated ALT concentrations (>39 U/L for boys and >33 U/L for girls) will be included. All children will be randomly allocated to consume control or plant stanol ester enriched soft chews on a daily basis for a period of 6 months. After 12 months there will be an additional blood sample to evaluate whether the 6 months intervention is still effective.
Nonalcoholic fatty liver disease (NAFLD) is the most common and harmful chronic liver disease. NAFLD accounts for 49.3% of the total number of chronic liver disease patients in China. It is important to effectively prevent and control NAFLD and its related diseases. Previous studies show the level of serum uric acid is significantly elevated in patients with NAFLD. Xanthine oxidase is a key enzyme in uric acid metabolism. It is a new therapeutic target for NAFLD. This study is aimed to further confirm that hyperuricemia is a new risk factor for NAFLD through a large sample prospective study. Furthermore, this study explore whether Xanthine oxidase (XO), a key enzyme in uric acid metabolism, plays an important role in regulating NAFLD.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver disease worldwide affecting as much as 25% of the world's population. The spectrum of NAFLD ranges from non-alcoholic fatty liver to non-alcoholic steatohepatitis (NASH), the latter being associated with a progressive course towards fibrosis and a higher risk of developing cirrhosis and hepatocellular carcinoma. Patients with type 2 diabetes are particularly at higher risk of developing fibrosis and advanced liver disease. Since NASH and its consequences will only occur in a minority of patients, it is of paramount importance to identify this population to offer them proper care. It is well known that there is a lack of awareness about the potential consequences of NAFLD, not only in the general population but also in the medical community. Patients with NAFLD are frequently lost during follow up and, additionally, approach to these patients is sub-optimal and heterogeneous among physicians. An attractive approach to applying best medical practices to patients with NAFLD is to generate a multicentre registry. Clinical registries comprise a set of systematic collected and stored data focused on a specific condition. The information stored in a registry provides relevant information about a disease and, through a process of error detection, ensures data quality and reliability. A NAFLD registry is an essential tool for providing relevant information such as epidemiological aspects of the disease, outcomes, and treatment effectiveness. As far as we concern, this would be the first registry of NAFLD in our region, a region where the disease behaves in a more aggressive way in comparison with other regions and hemispheres. By generating this registry, we are confident that we will obtain objective information on the characteristic of patients with NAFLD in our region, not only of the disease characteristics but also of social determinants that might influence disease outcomes. By being a prospective study, it allows an adequate patient follow up.
The aim of our study is: 1. The early detection of NAFLD in CKD patients with different stages (stage I to IV) to avoid progression to liver fibrosis. 2. Evaluation of the relationship between the severity of fatty liver in NAFLD assessed by liver enzymes, biochemical markers, ultrasonography and grades of Fibroscan with CKD staging, eGFR and proteinuria.
