Abcs Of Probiotics For IBS
By Patty Goff
The intestinal colonization by biotics is temporary and ends a few days after cessation of their employment. The benefits described in the various studies are not always to be understood as general effects of probiotics for IBS. Every effect is attributable only to the single strain or individual strains tested in that regard. If a supplement with probiotics has yielded positive results in a study of a particular benefit.
It is also seen that some foods and probiotic supplements modulate the inflammatory response, and it is thought that this is due at least in part in the regulation of the function of cytokines with regard to the inflammatory response, for example, some clinical studies suggest that they can prevent relapse of inflammatory bowel disease (IBD, inflammatory bowel Disease) in adults.
Lactic acid bacteria (LAB) for the most part represented by lactobacilli, and bifidobacteria are the most common types of probiotic microorganisms, including some yeasts and bacilli may be useful. The lactic acid bacteria are commonly consumed along with the fermented foods that contain them - foods such as yogurt or soy yogurt with the addition of specific bacterial cultures alive and active.
But the two enzymes present in such products do not play a beneficial role in human organisms because they die as soon as they come into contact with the gastric juices. According to FAO / WHO guidelines, good bacteria are defined only those microorganisms that can demonstrate, when ingested in adequate amounts, exert beneficial functions in body.
It is still not clear how probiotics may counteract the overreaction of the immune system, but a potential mechanism seems to be the desensitization of T lymphocytes, an important component of the immune system, to pro-inflammatory stimuli. An interesting beneficial effect of some probiotic strains in this regard relates to atopic dermatitis and asthma in children; However, there are conflicting data in the literature. It does not seem that pro biotics can reduce the effects of persistent eczema and dermatitis.
Nobel laureate Eli Metchnikoff, who worked at the Pasteur Institute in the early years of the twentieth century, hypothesized that these effects arising from an improvement in intestinal microbial balance through inhibition of pathogenic bacteria. Since then, knowledge about biotics have been enriched by scientific and clinical studies in large numbers and with great frequency.
A probiotic strain widely studied in this context is that the Lactobacillus rhamnosus GG was able to reduce the duration of infectious diarrhea supported by rotavirus, common pathogen in children and an important cause of hospitalization. The guidelines of the American Academy of Pediatrics 2010, as in 2008 the guidelines (Society for Paediatric Gastroenterology, Hepatology and Nutrition) indicate that for the treatment of acute diarrhea the beneficial effect is strain-dependent and that Lactobacillus GG is to date the most effective probiotic, which already if administered at onset of acute diarrhea, is able to reduce the duration of about 1 day.
Lactic acid bacteria are considered useful in the treatment of Helicobacter infections pylor i (associated with peptic ulcers) in adults in combination with medications normally used for this purpose. However, further studies are needed in this area. As of May 2011, there were approximately 140 published studies involving probiotics and H. Pylori, which showed that the addition of probiotic yogurt containing triple eradication therapy did not increase the rate of eradication of H. Pylori, however, reduced the frequency of stomatitis and constipation.
