ABSTRACT Functional foods (specific nutrient and/or food components) should beneficially affect one or more target functions in the body. The use of functional foods as a form of preventive medicine has been the subject of much research over the last two decades. It is well known that nutrition plays a vital role in chronic diseases, but it is only recently that data relating to the effects of specific nutrients or foods on the immune system have become available. This chapter aims to summarize the effects of some functional foods (e.g., prebiotics and micronutrients) on the immune system. It should be noted, however, that studies into the role of functional foods with regard to the human immune system are still in their infancy and a great deal of controversy surrounds the health claims attributed to some functional foods. Consequently, thorough studies are required in human and animal systems if we are to move towards developing a functional diet that provides maximal health benefits.

    • "On the other hand, the term " functional foods " has been commonly used in marketing but still lacks a firm regulatory definition (BJelakOvic & Gluud, 2007). HOyles and Vulevic (2008) noticed that studies into the role of functional foods with regard to the human immune system are still in their infancy and a great deal of controversy surrounds the health claims attributed to some functional foods. Therefore, more studies are required in human and animal systems if we are to move towards developing a functional diet that provides maximal health benefits. "

    ABSTRACT: Die Leberzirrhose ist eine häufige Erkrankung, die aufgrund zahlreicher Komplikationen, die Spitalsaufnahmen nach sich ziehen, ein Problem für das Gesundheitssystem darstellt. Das akute Leberversagen hingegen ist selten, doch wenn es auftritt, sind zahlreiche schwerwiegende Komplikationen die Folge. Zu den wichtigsten Komplikationen, sowohl bei akuten als auch chronischen Lebererkrankungen, zählen Infektionen. In dieser Übersichtsarbeit werden Störungen des angeborenen Immunsystems bei Leberzirrhose, akut-auf-chronischem Leberversagen und akuten Leberversagen. Die bekannten Defekte der Kupffer-Zellen, neutrophilen Granulozyten und Monozyten werden besprochen. Weiters wird die pathophysiologische Relevanz der Darmpermeabilität, der portalen Hypertension sowie intrinsische zelluläre Defizite diskutiert und die Rolle von Endotoxin, Albumin, Lipoproteinen und Toll-like Rezeptoren herausgearbeitet. Basierend auf diesen pathophysiologischen Konzepten werden die verfügbaren therapeutischen Strategien präsentiert: Therapie mit Antibiotika, Probiotika, Ernährungstherapie und Leberunterstützungssysteme sowie experimentelle Strategien wie Toll-like Rezeptor Hemmung, Albumin oder Kolonie-stimulierende Faktoren. Liver cirrhosis is a common disease causing great public-health concern because of the frequent complications requiring hospital care. Acute liver failure is also prone to several complications but is rare. One of the main complications for both acute and chronic liver diseases is infection, which regularly causes decompensation of cirrhosis, possibly leading to organ failure and death. This review focuses on innate immune function in cirrhosis, acute-on-chronic liver failure and acute liver failure. The known defects of Kupffer cells, neutrophils and monocytes are discussed, together with the pathophysiological importance of gut permeability, portal hypertension and intrinsic cellular defects, and the role of endotoxin, albumin, lipoproteins and toll-like receptors. Based on these different pathomechanisms, the available information on therapeutic strategies is presented. Antibiotic and probiotic treatment, nutritional support, artificial liver support, and experimental strategies such as inhibition of toll-like receptors and use of albumin and colony-stimulating factors are highlighted.

    ABSTRACT: The World Health Organization estimates that liver cirrhosis will be the ninth most common cause of death in the Western world by 2015 (1). In a significant proportion of these patients, death is related to multiple organ failure. The term acute on chronic liver failure (ACLF) refers to the development of acute hepatic dysfunction in previously well-compensated cirrhotic patients following a precipitating event such as sepsis, variceal hemorrhage, or alcoholic hepatitis (2).
