Use of pro-, pre- and synbiotics in the ICU--future options

Abstract
Although the word synbiotics was coined to describe the combined action of pre- and probiotics, the ability to, like antibiotics, control infection, the term is now increasingly used in a wider sense, as a name for all the substances released by microbial fermentation in the lower gut. One obvious reason is that most of the substances released seem to influence the immune defense, increase resistance to disease, and, most important, prevent complications to surgery such as infections and thrombosis. Protection layer of lactobacillus does not exist only on the GI tract mucosa, it is important at all exterior body surfaces including those of the eye, the nose, the mouth, the respiratory tract, the vagina, not to forget the skin. It is clearly reduced at all sites when the patient is in the settings of ICU. Each human being has his/her own unique microbial collection, especially of strains of Bifidobacterium and Lactobacillus, and it should be possible to identify an individual on the basis of his/her personal intestinal microflora. The flora seems always to be significantly reduced in the sick, especially in connection with severe disease, care in ICU, and in patients with little food intake or on parenteral nutrition. Supply of both pre- and probiotics can modify functions such as appetite, sleep, mood and circadian rhythm, and this most likely through metabolites produced by microbial fermentation in the gut. Supply of lactic acid bacteria (LAB) can also significantly reduce serum levels of a variety of toxins such as endotoxin. An umbrella of supplemented probiotics could provide to the patients with liver cirrhosis a tool to reduce septic manifestations and the incidence of bleeding. LAB are effective in controlling diarrhea of both bacterial and viral origin. A series of experimental studies and several uncontrolled clinical studies support the idea of using probiotics in patients with IBD. Ecoimmunonutrition with pre- pro- and synbiotics offer to be suitable tools in the new millennium.
