NAFLD in the Absence of Metabolic Syndrome: Different Epidemiology, Pathogenetic Mechanisms, Risk Factors for Disease Progression?
Full text linkMetabolic syndrome (MetS) is a cluster of metabolic abnormalities that have been associated with an increased risk of developing nonalcoholic fatty liver disease (NAFLD). Insulin resistance and central obesity are the key components of MetS, ultimately leading to liver fat accumulation and the subsequent development of necroinflammatory liver injury. However, the origin and nature of the metabolic stressors responsible for stimulating the progression of simple steatosis to nonalcoholic steatohepatitis (NASH) remain to be clearly identified. In addition, epidemiologic research on the association between MetS and NAFLD has provided only limited information to guide the development of targeted interventions, in particular, nutrition and pharmacologic prevention programs. This review summarizes the evidence supporting the proposal that NAFLD is not invariably associated with the presence of MetS, and mechanisms other than insulin resistance may contribute to the chronic inflammatory processes that underpin the development of liver fat accumulation and the subsequent architectural distortion of the liver. A special focus is given to increased hemoglobin as a risk factor for the development of NAFLD in the absence of MetS
Serum proteomics for biomarker discovery in nonalcoholic fatty liver disease
No full textProteomic platforms have gained increasing attention in the clinical spectrum of nonalcoholic fatty liver disease (NAFLD). This approach allows for the unbiased discovery of circulating biochemical markers, i.e., it is not limited to known molecules of presumed importance. This manuscript provides an overview of proteomic serum biomarker discovery in NAFLD. Hemoglobin is currently the most widely replicated proteomic circulating biomarker of NAFLD; it was identified as a biomarker of fatty liver in two distinct proteomic studies and subsequently validated using distinct analytical methods by independent research groups in large replication cohorts. Given the increasing availability of numerous serum samples and the refinement of the technological platforms available to scrutinize the blood proteome, large collaborative studies between academia and industry are warmly encouraged to identify novel, unbiased circulating biomarkers of NAFLD.

No full textPatients with hepatic disorders are exceptionally vulnerable to developing malnutrition because of the key role played by the liver in regulating the nutritional state and the energy balance. Moreover, the presence of chronic liver disorders could reduce the appetite and thus influence the nutrient intake. Poor nutritional status has been shown in various patient groups with hepatic disorders, and particularly in patients with alcoholic cirrhosis who are at high nutritional risk. It is well established that malnourished patients with liver diseases generally have a higher risk of developing adverse clinical outcomes and increased healthcare costs. Nutrition screening with the Subjective Global Assessment and anthropometric measurements are an important first step in the early identification of malnutrition and initiates the whole nutrition care process. It is therefore important for appropriate nutrition policies and protocols to be implemented so that all patients with chronic liver diseases are monitored closely from a nutritional standpoint. Early and evidence-based nutritional interventions are eagerly needed to minimize the nutritional decline associated with chronic liver disorders and ultimately improve the prognosis of such patients. This review includes a comprehensive analysis of methods to identify malnutrition in patients with chronic liver diseases as well as the extent and impact of the malnutrition problem in selected patient populations.
