Abstract
Many patients with infammatory bowel disease use alteranative therapy, mainly probiotics and synbiotics, to
manage this intestinal condition. Despite widespread use of these natural therapies by patients, health care providers
may be unfamiliar with probiotics as a treatment modality. This review describes the rationale for use of probiotics
in patients with active or inactive infammatory bowel disease, their mechanism(s) of action, and recent controlled
clinical studies in which effcacy of probiotics, prebiotics and synbiotics in patients with active or inactive infammatory
bowel disease has been explored. Certain probiotics, particularly E. coli Nissle 1917 and a multi-agent mixture
VSL#3, may be beneft patients with UC or pouchitis, while LactoBacillus rhamnosus GG appears less useful. In
general, probiotics show potential for therapeutic application mainly in pouchitis and to a lesser degree in UC, while
their effects in maintenance therapy for CD have been much less promising. While there is suggestion of beneft
when patients with ulcerative colitis use bacterial therapies small sample sizes and methodological weeknesses
in study designs necessitate that additional studies must be conducted before probiotics and or synbiotics can be
routinely recommended in clinical practice.

Introduction
Te normal colonic microfora is intimately involved in the
aetiology of infammatory bowel disease (IBD). Both ulcerative
colitis (UC) and Crohn’s disease (CD) are quite ofen refractile to
conventional treatment thus requiring the use of alternative therapies
based for example on the use of probiotics, prebiotics or combination
of the two (synbiotics).
So far, most of the studies in this area have been performed using
probiotics, and although an increasing interest on the use of synbiotics
has been noticed recently, few randomised controlled trials have been
conducted concerning both murine models of IBD and humans.
Te available clinical and experimental data suggest that these
functional foods can alter the composition of the colonic microbiota,
and reduce infammatory processes in the gut mucosa, thus having the
potential to induce disease remission especially in patients sufering
from UC.
In this review we will try to clarify the role of prebiotics, probiotics,
and synbiotics on the clinical course of patients with IBD based on the
results of the current literature.
Defnitions
Probiotics are live microorganisms that when ingested in adequate
quantities, exert a health beneft to the host. Inactivated bacteria or
bacteria derived factors can also have probiotic properties, and thus
might be considered as probiotics. Te main probiotic preparations
commercially available belong to a group of Gram-positive fermentative
bacteria that are associated with the production of lactic acid from
carbohydrates. Species of LactoBacillus, Lactococcus, Bifdobacterium
and Streptococcus thermophilus are included in this group, being
normal as well as important constituents of the human gastrointestinal
microfora [1]. Potential probiotic roles probably share some other
microbes including yeasts (Saccharomyces boulardii, Saccharomyces
cerevisiae) and non-pathogenic strains of E. coli and Bacillus species.
Prebiotics are dietary substances (mostly consisting of non-starch
polysaccharides and oligosaccharides not or poorly digested by human
enzymes) that benefts the host by selectively stimulating the growth and
activity of indigenous probiotic bacteria. According to the International
Scientifc Association for Probiotics and Prebiotics “a dietary prebiotic
is a selectively fermented ingredient that results in specifc changes, in
the composition and/or activity of the gastrointestinal microbiota, thus
conferring beneft(s) upon host health [2].” Te majority of prebiotics
includes fbres and carbohydrates, such as resistant starch, wheat bran,
and inulin. Teir presence in the bowel lumen selectively enhances
proliferation of certain probiotic bacteria, especially Bifdobacteria
species. Tey also act as carbon and energy sources for bacteria growth
in the large bowel, where they are fermented into short chain fatty
acids, lactate, CO
2
, and H
2
formation being energy sources for the gut
mucosa especially of the lef colon [3].
Synbiotics is a novel approach combining probiotics and prebiotics
in an attempt to obtain synergistic efects of the two compounds by
improvement of the probiotic colonisation or the metabolic efect.
Although the number of microorganisms that must be ingested to
obtain a benefcial efect is largely unknown, a probiotic should contain
several billion microorganisms to increase the chance of adequate gut
colonization [4]. It must be stressed however, that probiotic benefts
associated with one strain do not necessarily hold true for other.
Frequency of probiotic use by the patients with IBD
Te most widely used probiotics are Saccharomyces boulardii
