Abstract
BACKGROUND Ileal pouch-anal anastomosis (IPAA) is the standard of care after total proctocolectomy for ulcerative colitis (UC). Around 50% of patients will experience pouchitis, an idiopathic inflammatory condition. Antibiotics are the backbone of treatment of pouchitis; however, antibiotic-resistant pouchitis develops in 5-10% of those patients. It has been shown that fecal microbiota transplantation (FMT) is an effective treatment for UC, but results for FMT antibiotic-resistant pouchitis are inconsistent. METHODS To uncover which metabolic activities were transferred to the recipients during FMT and helped the remission, we performed a longitudinal case study of the gut metatranscriptomes from three patients and their donors. The patients were treated by two to three FMTs, and stool samples were analyzed for up to 140 days. RESULTS Reduced expression in pouchitis patients compared to healthy donors was observed for genes involved in biosynthesis of amino acids, cofactors, and B vitamins. An independent metatranscriptome dataset of UC patients showed a similar result. Other functions including biosynthesis of butyrate, metabolism of bile acids, and tryptophan were also much lower expressed in pouchitis. After FMT, these activities transiently increased, and the overall metatranscriptome profiles closely mirrored those of the respective donors with notable fluctuations during the subsequent weeks. The levels of the clinical marker fecal calprotectin were concordant with the metatranscriptome data. Faecalibacterium prausnitzii represented the most active species contributing to butyrate synthesis via the acetyl-CoA pathway. Remission occurred after the last FMT in all patients and was characterized by a microbiota activity profile distinct from donors in two of the patients. CONCLUSIONS Our study demonstrates the clear but short-lived activity engraftment of donor microbiota, particularly the butyrate biosynthesis after each FMT. The data suggest that FMT triggers shifts in the activity of patient microbiota towards health which need to be repeated to reach critical thresholds. As a case study, these insights warrant cautious interpretation, and validation in larger cohorts is necessary for generalized applications. In the long run, probiotics with high taxonomic diversity consisting of well characterized strains could replace FMT to avoid the costly screening of donors and the risk of transferring unwanted genetic material.

Abstract
The gut microbiome has been implicated in a range of diseases and there is a rapidly growing understanding of this ecosystem's importance in inflammatory bowel disease. We are yet to identify a single microbe that causes either ulcerative colitis (UC) or pouchitis, however, reduced microbiome diversity is increasingly recognised in active UC. Manipulating the gut microbiome through dietary interventions, prebiotic and probiotic compounds and faecal microbiota transplantation may expand the therapeutic landscape in UC. Specific diets, such as the Mediterranean diet or diet rich in omega-3 fatty acids, may reduce intestinal inflammation or potentially reduce the risk of incident UC. This review summarises our knowledge of gut microbiome therapies in UC and pouchitis.

Abstract
AIMS This pilot study assessed the efficacy, safety, and microbiome dynamics of fecal microbiota transplantation (FMT) for patients with chronic pouchitis. METHODS A prospective open-label pilot study was performed at an academic center among pouchitis patients undergoing FMT. Patients received a minimum of a single FMT by pouchoscopy from healthy, screened donors. The primary outcome was clinical improvement in pouchitis assessed by patient survey at week 4. Secondary outcomes included decrease in total Pouchitis Disease Activity Index (PDAI) Score ≥ 3 at week 4, bowel movement frequency, ESR, CRP, fecal calprotectin, abdominal pain, and PDAI subscores including endoscopic and histologic changes. Stool samples were collected at baseline and 4 weeks post-FMT to assess bacterial microbiota using V4 16S rRNA sequencing. RESULTS Nineteen patients were enrolled; however, 1 patient was lost to follow-up. No patients had a major adverse event or escalation of therapy related to FMT. Total PDAI scores, endoscopic scores, and histologic scores did not decrease significantly post-FMT. However, there was a statistically significant improvement in bowel movement (BM) frequency (9.25-7.25 BM/day, p = 0.03) and trend for improvement in abdominal pain to improve post-FMT (p = 0.05). Bacterial microbiota profiling revealed no distinct community-level changes post-FMT, though a small number of specific bacterial taxa significantly differed in relative abundance. CONCLUSIONS A single FMT has a tolerable short-term safety profile and may be associated with a decrease in bowel movements in patients with chronic pouchitis; however, no robust endoscopic or histologic changes were observed.

Abstract
Intestinal microbiota are involved in the pathogenesis of Crohn's disease, ulcerative colitis, and pouchitis. We review the mechanisms by which these gut bacteria, fungi, and viruses mediate mucosal homeostasis via their composite genes (metagenome) and metabolic products (metabolome). We explain how alterations to their profiles and functions under conditions of dysbiosis contribute to inflammation and effector immune responses that mediate inflammatory bowel diseases (IBD) in humans and enterocolitis in mice. It could be possible to engineer the intestinal environment by modifying the microbiota community structure or function to treat patients with IBD-either with individual agents, via dietary management, or as adjuncts to immunosuppressive drugs. We summarize the latest information on therapeutic use of fecal microbial transplantation and propose improved strategies to selectively normalize the dysbiotic microbiome in personalized approaches to treatment.

Abstract
AIM To investigate the changes in microbiota in feces of patients with ulcerative colitis (UC) and pouchitis using genomic technology.
METHODS Fecal samples were obtained from UC patients with or without an ileal pouch-anal anastomosis (IPAA) procedure, as well as healthy controls. The touchdown polymerase chain reaction technique was used to amplify the whole V3 region of the 16S rRNA gene, which was transcribed from DNA extracted from fecal samples. Denaturing gradient gel electrophoresis was used to separate the amplicons. The band profiles and similarity indices were analyzed digitally. The predominant microbiota in different groups was confirmed by sequencing the 16S rRNA gene.
RESULTS Microbial biodiversity in the healthy controls was significantly higher compared with the UC groups (P < 0.001) and IPAA groups (P < 0.001). Compared with healthy controls, the UC patients in remission and those in the mildly active stage, the predominant species in patients with moderately and severely active UC changed obviously. In addition, the proportion of the dominant microbiota, which was negatively correlated with the disease activity of UC (r = -6.591, P < 0.01), was decreased in pouchitis patients. The numbers of two types of bacteria, Faecalibacterium prausnitzii and Eubacterium rectale, were reduced in UC. Patients with pouchitis had an altered microbiota composition compared with UC patients. The microbiota from pouchitis patients was less diverse than that from severely active UC patients. Sequencing results showed that similar microbiota, such as Clostridium perfringens, were shared in both UC and pouchitis.
CONCLUSION Less diverse fecal microbiota was present in patients with UC and pouchitis. Increased C. perfringens in feces suggest its role in the exacerbation of UC and pouchitis.

Abstract
AIM Clostridium difficile infection (CDI) of the ileal pouch following restorative proctocolectomy (RPC) is becoming increasingly recognized. We aimed to understand better (i) the associated risk factors, (ii) treatment practices and (iii) the pouch diversion and failure rate in patients who developed CDI of the pouch after RPC for ulcerative colitis (UC). METHOD Patients who tested positive for C. difficile of the pouch between 2007 and 2010 were included in the analysis. Data collected included patient demographics, time from RPC to documented CDI, the treatment of CDI and rate of excision of the pouch. RESULTS Of 2785 patients recorded in the hospital CDI database, 15 had had an RPC with ileal pouch anal anastomosis. The median age was 44 years and the median interval from RPC to first documented episode of CDI was 3 years. Thirteen (81%) patients had had multiple episodes of pouchitis before and after CDI infection, and all were symptomatic at the time of testing for CDI. Within 30 days of the diagnosis of CDI, six (40%) patients were taking immunosuppressive medication, seven (47%) were taking a proton pump inhibitor and 12 (80%) had received antibiotics. Five patients required hospitalization for CDI and four had severe infections characterized by a serum creatinine more than 1.5 times baseline (n = 3) and a white cell count above 15 000 (n = 1). Six patients who underwent endoscopy had severe inflammation of the pouch including the presence of a pseudomembrane in one case. Ten patients were treated with metronidazole alone and five with vancomycin. Two patients had recurrent CDI of the pouch during a median follow-up period of 2.9 years and one had CDI refractory to medical management. This patient required diversion of the pouch with an ileostomy for refractory CDI but no patient required excision of the pouch. CONCLUSION All 15 patients developing CDI of the pouch were successfully treated with antibiotics and only one required surgery in the form of an ileostomy.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is increasingly recognized in patients with ulcerative colitis with ileal pouch-anal anastomosis (IPAA). The aim of this study was to identify clinical risk factors for treatment-refractory or recurrent CDI in patients with IPAA. METHODS We identified patients with IPAA for underlying ulcerative colitis and a positive polymerase chain reaction stool test for C. difficile at the Center for Ileal Pouch Disorders during the period from October 2010 to November 2013. Demographic clinical variables were compared between the refractory or recurrent CDI and nonrecurrent CDI groups. RESULTS Patients with IPAA with refractory or recurrent symptoms (refractory/recurrent CDI, the study group, N = 19) were compared with patients with a single antibiotic-responsive episode of ileal pouch CDI (nonrecurrent CDI, the control group, N = 21). The frequency of pouchitis before the index CDI was similar in the study and control groups (63.2% versus 66.7%, P = 0.82). Postoperative mechanical abnormalities occurred in 16 patients (84.2%) in the study group versus 7 patients (33.3%) in the control group (P = 0.0008). There were no differences between the two groups regarding hospitalization, non-C. difficile antibiotic use, the use of gastric acid-reducing therapy, or immunosuppressives before or after the index CDI. Six of 15 patients (40.0%) in the study group versus 1 of 15 patients (7.1%) in the control group had a low serum level of IgG1 (P = 0.031). CONCLUSIONS Refractory or recurrent disease is common in patients with ileal pouch with CDI. The presence of postsurgery mechanical intestinal complications or low serum immunoglobulin level may be risk factors for refractory or recurrent CDI in this patient population.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the surgical treatment of choice for many patients with medically refractory ulcerative colitis (UC) and familial adenomatous polyposis (FAP). UC patients with IPAA (UC-IPAA) are, nevertheless, susceptible to inflammatory and noninflammatory sequelae such as pouchitis, which is only rarely noted in FAP patients with IPAA. Pouchitis is the most frequent long-term complication of UC-IPAA patients, with a cumulative prevalence of up to 50%. Although the aetiology of pouchitis remains unclear, accumulating evidence suggests that a dysbiosis of the pouch microbiota and an abnormal mucosal immune response are implicated in its pathogenesis. Studies using culture and molecular techniques have detected a dysbiosis of the pouch microbiota in patients with pouchitis. Risk factors, genetic associations, and serological markers suggest that interactions between the host immune response and the pouch microbiota underlie the aetiology of this idiopathic inflammatory condition. This systematic review focuses on the dysbiosis of the microbiota that inhabit the pouch in UC and FAP patients and its interaction with the mucosal immune system. A meta-analysis was not attempted due to the highly heterogeneous microbiota composition and the different detection methods used by the various studies. Although no specific bacterial species, genus, or family has as yet been identified as pathogenic, there is evidence that a dysbiosis characterized by decreased gut microbiota diversity in UC-IPAA patients may, in genetically predisposed subjects, lead to aberrant mucosal immune regulation triggering an inflammatory process.

Abstract
Pouchitis occurs in up to one half of patients after restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Cytomegalovirus (CMV) and Clostridium difficile are among the commonest secondary identifiable etiologies. A 17-year-old male with ulcerative colitis underwent IPAA due to refractory disease. Nine months later he experienced bloody diarrhea and fever. Laboratory testing and endoscopy confirmed pouch inflammation. Testing for C. difficile toxins A and B was positive. Histology revealed affluent inclusion bodies and immunohistochemistry detected reactivity against CMV protein. Treatment with metronidazole and vancomycin offered partial improvement, whereas the addition of gancyclovir led to a successful recovery. One month after completion of treatment symptoms recurred. Repeat testing precluded an identifiable infectious cause and the diagnosis of idiopathic chronic pouchitis was established. The patient is currently on maintenance treatment with the probiotic compound VSL#3.

Abstract
BACKGROUND Chronic pouchitis is an important long-term complication following ileal pouch-anal anastomosis for ulcerative colitis. Antibiotic administration reduces symptoms of pouchitis, indicating that bacteria have a role in pathogenesis. The aim of the research was to investigate the bacterial content of pouches using nucleic acid-based methods. METHODS Stool microbiota of 17 patients with normal pouches (NP), 17 patients with pouchitis (CP) utilizing samples collected from each patient when antibiotic-treated (CP-on, asymptomatic) and when untreated (CP-off, symptomatic), and 14 familial adenomatous polyposis (FAP) patients were analyzed by high-throughput sequencing, fluorescence in situ hybridization technologies, and quantitative polymerase chain reaction (qPCR). RESULTS Fluorescence in situ hybridization analysis revealed an expanded phylogenetic gap in NP and CP-off patients relative to FAP. Antibiotic treatment reduced the gap in CP stool. The phylogenetic gap of CP-off patients was due to members of the bacterial families Caulobacteriaceae, Sphingomonadaceae, Comamonadaceae, Peptostreptococcaceae, and Clostridiaceae. There was a greater diversity of phylotypes of Clostridiaceae in CP-off subjects. The phylogenetic gap of NP stool was enriched by Ruminococcaceae and Bifidobacteriaceae. CP stool microbiota had reduced diversity relative to NP and FAP stool due largely to a reduction in Lachnospiraceae/Insertae Sedis XIV/clostridial cluster IV groups. CONCLUSIONS Bacterial groups within the expanded phylogenetic gap of pouch patients may have roles in the pathogenesis of pouchitis. Further research concerning the physiology of cultured members of these groups will be necessary to explain their specific roles. Members of the Lachnospiraceae, Incertae Sedis XIV, and clostridial cluster IV could be useful biomarkers of pouch health.

Abstract
Human subjects and their enteric microbiota have evolved together to reach a state of mutual tolerance. Mounting evidence from both animal models and human studies suggests that inflammatory bowel disease (IBD) represents a malfunction of this relationship. The enteric microecology therefore represents an attractive therapeutic target with few side effects. Probiotics and prebiotics have been investigated in clinical trials as treatments for IBD, with conflicting results. The evidence for the use of probiotics in the management of pouchitis is persuasive and several studies indicate their effectiveness in ulcerative colitis. Trials of probiotics and prebiotics in Crohn's disease are less convincing. However, methodologies vary widely and a range of probiotic, prebiotic and combination (synbiotic) treatments have been tested in a variety of patient groups with an assortment of end points. Conclusions about any one treatment in a specific patient group can therefore only be drawn on evidence from relatively small numbers of patients. The present article reviews the role of the intestinal microbiota in the pathogenesis of IBD and addresses the clinical evidence for the therapeutic manipulation of bowel microbiota using probiotics, prebiotics and synbiotics in IBD.

Abstract
BACKGROUND & AIMS Pouch inflammation after surgery for ulcerative colitis can significantly alter quality of life and thus ideally should be prevented. Dysbiosis or altered microflora is suspected to be the key pathogenic factor for pouchitis. However, dysbiosis in pouchitis has not been characterized carefully because of a lack of available sensitive microbiological technology suitable for in vivo studies in human beings. Thus, the aims of our study were as follows: (1) to show the use of the length heterogeneity polymerase chain reaction (LH-PCR) technique for studying microflora in human beings, and (2) to use the technique to characterize the microfloral patterns in the ileal pouch of patients with pouchitis. METHODS Microfloral patterns initially were assessed using a 16S ribosomal RNA technique (LH-PCR) to determine the qualitative changes in the luminal and mucosal intestinal flora. We subsequently cloned and sequenced the LH-PCR amplification products from the community 16S ribosomal RNA found in patients with pouchitis and in control pouch to identify the microbial species involved in pouchitis. RESULTS We have shown unique microfloral patterns in pouchitis. Through cloning and sequencing of the LH-PCR amplicons, we have shown the persistence of Fusobacter and Enteric species associated with the disease state and the absence of specific bacteria such as Streptococcus species in the inflamed pouch. CONCLUSIONS We have shown that the LH-PCR technique is suitable for studying microflora in human beings. By using this technique and the clone sequences, we have shown dysbiosis in the microbial biofilm adherent to the mucosa in pouchitis. Our data provide direct evidence of the role of bacteria in the pathogenesis of pouchitis.

Abstract
BACKGROUND AND METHODS The exact aetiology of pouchitis is unknown, but an association with dysbiosis has been suggested. This is a retrospective review of 17 studies published between 1985 and 2005, identified by a search of the Medline, Pubmed and Embase databases. RESULTS The methodology of the studies varied widely. Many were performed at a time when the distinction between a healthy and an inflamed pouch was vague; misclassification of patients makes the analysis of data difficult and conclusions uncertain. CONCLUSION The evidence that dysbiosis is a cause of pouchitis is poor. Nevertheless, available data allow the construction of an algorithm to aid management and suggest a structured approach for future research.

Abstract
Pouchitis is the most common long-term sequela of ileal pouch-anal anastomosis (IPAA) following total proctocolectomy. No single pathogen is identified as being solely responsible for the pathogenesis of the disease. Here we describe a case of Clostridium difficile-associated pouchitis that was successfully treated with ciprofloxacin and tinidazole. Diagnosis and management of a patient with medically refractory pouchitis associated with Clostridium difficile infection is described. A 63-year-old male with underlying ulcerative colitis and IPAA presented with increased stool frequency and seepage for 2 months, which partially responded to oral metronidazole. While on the antibiotic therapy, pouch endoscopy was performed and showed severe pouchitis. Assays for Clostridium difficile toxins in stool specimens were positive. He was treated with a 4-week course of ciprofloxacin 500 mg BID and tinidazole 500 mg TID. His symptoms resolved within several days from the initiation of therapy. A repeat pouch endoscopy at week 5 showed a complete resolution of mucosal inflammation of the pouch, while tests for Clostridium difficile toxins became negative. Clostridium difficile-associated pouchitis is rare. However, Clostridium difficile infection should be excluded in patients with chronic refractory pouchitis.

Abstract
Probiotics are live nonpathogenic bacteria or bacterial components that may be helpful in the prevention and treatment of acute diarrhoea in adults and children and have some effects on the course of inflammatory bowel diseases (IBD). Many experimental and clinical studies suggest that intestinal bacterial flora plays an important role in the pathogenesis of IBD, and manipulation of the luminal contents with antibiotics or probiotics represents a potentially effective therapeutic option. The beneficial effect of probiotics was demonstrated mainly in the prevention and treatment of pouchitis and in maintaining remission of mild to moderate ulcerative colitis. Probiotics seems to be less effective in patients with Crohn's disease. Randomized clinical trials are still required to further define the role of probiotics as preventive and therapeutic agents. This review summarizes the current data about probiotics in IBD.

Abstract
BACKGROUND AND AIMS Bacterial overgrowth appears to play an important role in the pathogenesis of ileoanal pouches. Therefore, the capability of bacterial permeation and its determinants is of great interest. The aim of this study was to examine bacterial permeation in the ileoanal pouch and to correlate the results with the degree of inflammation, the epithelial resistance, the mucosal transport function, and the age of the ileoanal pouches. MATERIALS AND METHODS Biopsies were taken from 54 patients before colectomy (n = 13; preileal pouch-anal anastomosis [IPAA]), and closure of ileostomy (n = 7; deviation), <1 year after closure of ileostomy (n = 8; intact pouch I), >1 year after closure of ileostomy (n = 16; intact pouch II), in the case of pouchitis (n = 11), and in 11 controls. Tissues were mounted in a miniaturized Ussing chamber. Escherichia coli was added to the mucosal side of the Ussing chamber, and the permeation was proven by serosal presence of E. coli. Epithelial and subepithelial resistance was determined by transmural impedance analysis. Active Na-glucose cotransport and active Cl secretion were measured. Specimens were analyzed by fluorescent in situ hybridization with oligonucleotide probes targeting the bacterial 16s ribosomal RNA. The bacteria in and on the tissue were enumerated. RESULTS Bacterial permeation occurred in 2 of 13 pre-IPAA, 2 of 7 deviations, 0 of 8 intact pouch I, 9 of 16 intact pouch II, 5 of 11 pouchitis specimens, and 0 of 11 ileum controls. The frequency of bacterial permeation in the intact pouch II group is higher than in the intact pouch I group (P < 0.001). Epithelial resistance, mannitol fluxes, electrogenic chloride secretion, sodium-glucose cotransport of the bacterially permeated specimens versus nonpermeated of the intact pouch II group, and the pouchitis group and subepithelial resistance remained unchanged. Intramural bacteria could be detected by fluorescence in situ hybridization mainly in long-lasting pouches, but there was no correlation with bacterial permeation. CONCLUSIONS The long-lasting ileoanal pouch is associated with increased bacterial permeability. This is not correlated with a disturbed function of the pouch mucosa but could be a precursor of pouchitis.

Abstract
Many experimental and clinical observations suggest that intestinal microflora plays a potential role in the pathogenesis of inflammatory bowel disease (IBD). Manipulation of the luminal content using antibiotics or probiotics represents a potentially effective therapeutic option. The available studies do not support the use of antibiotics in ulcerative colitis (UC). Antibiotics are effective in treating septic complications of Crohn’s disease (CD) but their use as a primary therapy is more controversial, although this approach is frequently and successfully adopted in clinical practice.
There is evidence that probiotic therapy may be effective in the prevention and treatment of mild to moderate UC. In contrast, a lack of successful study data at present precludes the widespread use of probiotics in the treatment of CD.
Both antibiotics and probiotics appear to play a beneficial role in the treatment and prevention of pouchitis and further trials are warranted to fully quantify their clinical efficacy.

Abstract
BACKGROUND The intestinal microbiota plays a critical role in the pathophysiology of pouchitis, a major complication after ileal pouch anal anastomosis in patients with ulcerative colitis. Recently, controlled trials have demonstrated that probiotics are effective in maintenance of remission in pouchitis patients. However, the mechanism by which therapy with probiotics works remains elusive. This study explores the role of the bacterial and fungal flora in a controlled trial for maintenance of remission in pouchitis patients with the probiotic VSL#3 compound. METHODS The mucosa associated pouch microbiota was investigated before and after therapy with VSL#3 by analysis of endoscopic biopsies using ribosomal DNA/RNA based community fingerprint analysis, clone libraries, real time polymerase chain reaction (PCR), and fluorescence in situ hybridisation. Patients were recruited from a placebo controlled remission maintenance trial with VSL#3. RESULTS Patients who developed pouchitis while treated with placebo had low bacterial and high fungal diversity. Bacterial diversity was increased and fungal diversity was reduced in patients in remission maintained with VSL#3 (p = 0.001). Real time PCR experiments demonstrated that VSL#3 increased the total number of bacterial cells (p = 0.002) and modified the spectrum of bacteria towards anaerobic species. Taxa specific clone libraries for Lactobacilli and Bifidobacteria showed that the richness and spectrum of these bacteria were altered under probiotic therapy. CONCLUSIONS Probiotic therapy with VSL#3 increases the total number of intestinal bacterial cells as well as the richness and diversity of the bacterial microbiota, especially the anaerobic flora. The diversity of the fungal flora is repressed. Restoration of the integrity of a "protective" intestinal mucosa related microbiota could therefore be a potential mechanism of probiotic bacteria in inflammatory barrier diseases of the lower gastrointestinal tract.

Abstract
BACKGROUND/AIMS Pouchitis is the most frequent complication of ileal pouch-anal anastomosis for patients with ulcerative colitis. While the mechanism of pouchitis is still unknown, a role involving the bacterial flora is suspected. The aim of the present study is to investigate the association between pouchitis and change in the bacterial flora. METHODOLOGY This study included 22 patients who underwent ileal pouch-anal anastomosis in our department to treat ulcerative colitis. The mean age was 46.2 years. The male-to-female ratio was 10:12. The mean interval between surgery and this study was 95.6 months. Collected feces was serially diluted 10-fold to 10-8 and each solution was cultured. We diagnosed pouchitis using the pouchitis disease activity index. RESULTS Nine of the 22 patients were diagnosed as having pouchitis. In the obligate anaerobes, the numbers of Bacteroidaceae and Bifidobacterium were significantly lower in the pouchitis group (P<0.01 and P<0.001). In the facultative anaerobic bacteria, the number of Lactobacillus was significantly lower in the pouchitis group (P<0.05). CONCLUSIONS The numbers of Bacteroidaceae, Bifidobacterium and Lactobacillus were significantly lower in the bacterial flora of the pouchitis group. Our findings suggest that there is an association between change in the bacterial flora and pouchitis.

Abstract
INTRODUCTION The resolution of pouchitis with metronidazole points to an anaerobic aetiology. Pouchitis is mainly seen in patients with ulcerative colitis pouches (UCP). We have recently found that sulphate reducing bacteria (SRB), a species of strict anaerobe, colonize UCP exclusively. Herein, we aimed to correlate levels of different bacterial species (including SRB) with mucosal inflammation and morphology. METHODS Following ethical approval, fresh faecal samples and mucosal biopsies were taken from 9 patients with UCP and 5 patients with familial adenomatous polyposis pouches (FAPP). For the purposes of comparison, faecal samples and mucosal biopsies were also taken from the stomas of 7 of the 9 patients with UC (UCS). Colonization by four types of strict anaerobes (SRB, Clostridium perfringens, Bifidobacteria and Bacteroides) as well as by three types of facultative anaerobes (Enterococci, Coliforms and Lactobacilli) was evaluated. Inflammatory scores and mucosal morphology were assessed histologically in a blinded fashion by a pathologist. RESULTS In general, strict anaerobes predominated over facultative in the UCP (P = 0.041). SRB were present in UCP exclusively. Even after exclusion of SRB from total bacterial counts, strict anaerobes still predominated. In the UCS, facultative anaerobes predominated. Strict and facultative anaerobes were present at similar levels in the FAPP. Enterococci were present at significantly reduced levels in the UCP when compared with the UCS (P = 0.031). When levels of SRB and other anaerobic species were individually correlated with mucosal inflammation and morphology, no trends were observed. CONCLUSION We have previously identified that SRB exclusively colonize UCP. In addition we have now identified a novel increase in the strict/facultative anaerobic ratio within the UCP compared to UCS. These stark differences in bacterial colonization, however, appear to have limited impact on mucosal inflammation or morphology.

Abstract
PURPOSE The beneficial effect of antibiotics in pouchitis suggests that an unidentified fecal bacterial product causes this condition. A candidate compound is hydrogen sulfide, a highly toxic gas produced by certain fecal bacteria, which causes tissue injury in experimental models. We investigated hydrogen sulfide release and sulfate-reducing bacterial counts in pouch contents to determine whether hydrogen sulfide production correlates with pouchitis. METHODS During incubation at 37 degrees C, the production of hydrogen sulfide, methylmercaptan, carbon dioxide, and hydrogen were studied using fresh fecal specimens obtained from 50 patients with ileoanal pouches constructed after total proctocolectomy for ulcerative colitis (n = 45) or for familial adenomatous polyposis (n = 5). Patients with ulcerative colitis were divided into five groups: a) no history of pouchitis (pouch for at least 2 years; n = 8); b) past episode(s) of pouchitis but no active disease for the previous year (n = 9); c) pouchitis in the past year but presently inactive (n = 9); d) ongoing antibiotic treatment (metronidazole or ciprofloxacin) for pouchitis (n = 11); e) currently suffering from pouchitis (n = 8). RESULTS Release of hydrogen sulfide when pouchitis was active (6.06 +/- 1.03 micromol g(-1) 4 h(-1)) or had occurred in the past year (4.71 +/- 0.41 pmol g(-1) 4 h(-1)) was significantly higher (P < 0.05) than when pouchitis had never occurred (1.71 +/- 0.43 micromol g(-1) 4 h(-1)) or had been inactive in the past year (2.62 +/- 0.49 micromol g(-1) 4 h(-1)). Antibiotic therapy was associated with very low hydrogen sulfide release (0.68 +/- 0.29 micromol g(-1) 4 h(-1)). Pouch contents from familial adenomatous polyposis patients produced significantly less hydrogen sulfide (0.75 +/- 0.09 micromol g(-1) 4 h(-1)) than did any group of nonantibiotic-treated ulcerative colitis patients. Sulfate-reducing bacterial counts in active pouchitis (9.5 +/- 0.5 log10/g) were significantly higher than in those who never experienced pouchitis (7.38 +/- 0.32 log10/g), and these counts fell dramatically with antibiotic treatment. No statistically significant differences in carbon dioxide and hydrogen were observed among the groups not receiving antibiotics. CONCLUSIONS Pouch contents of patients with ongoing pouchitis or an episode within the previous year released significantly more hydrogen sulfide than did the contents of patients who never had an attack of pouchitis and those with longstanding inactive disease. The response to therapy with metronidazole or ciprofloxacin was associated with marked reductions in hydrogen sulfide release and sulfate-reducing bacteria. These results provide a rationale for additional studies to determine whether the high sulfide production is a cause or effect of pouchitis. The lower hydrogen sulfide production by pouch contents of familial adenomatous polyposis vs. patients with ulcerative colitis suggests a fundamental difference in gut sulfide metabolism that could have implications for the etiology of ulcerative colitis as well as the pouchitis of patients with ulcerative colitis.

Abstract
The pathogenic role of certain microorganism of intestinal flora has been demonstrated in experimental colitis in animals and strongly suspected in inflammatory bowel disease in human, especially in Crohn's disease and pouchitis. Probiotics are living non pathogenic microorganisms that, upon oral ingestion exert benefits on human health by modulating enteric flora or by stimulation of local immune system. The aim of this article is to remind the role of intestinal flora in inflammatory bowel disease, the mechanism of inflammation induced by this flora and to review through the literature, the different clinical studies performed with probiotics in human.

Abstract
BACKGROUND/AIMS The gut flora may play an important role in the pathogenesis of inflammatory bowel disease. An ileal reservoir or pouch can be created to replace the excised rectum after proctocolectomy. In patients with ulcerative colitis this is subject to inflammation and termed pouchitis. Using bacteria from patients the authors sought evidence for the presence rather than the identity of a pathogenic species in pouchitis, and for its absence in healthy pouches by the differential effect on lymphocyte proliferation. METHODS An ex vivo cell culture assay was used in which peripheral blood mononuclear cells or lamina propria mononuclear cells were cultured with sterile sonicates of gut flora from patients with or without pouchitis in the presence of antigen presenting cells. RESULTS Sonicated pouchitis flora produced a consistent and intense proliferation of the mononuclear cells but that produced by sonicates from healthy pouches was minimal (p = 0.012 or 0.018, peripheral blood or lamina propria mononuclear cells). Preparation of the sonicates with the antibiotic metronidazole abolished their stimulatory ability (p = 0.005, peripheral blood mononuclear cells). In separate assays neither direct addition of metronidazole nor of its hydroxy metabolite affected the mononuclear cells' proliferation with alternative stimuli. CONCLUSIONS These results strongly support a bacterial aetiology for pouchitis.

Abstract
PURPOSE Pouchitis has been associated with abnormal bacterial flora responding to antibiotics. Dietary factors may play a role in modifying the qualitative and quantitative components of the microflora. We evaluated interactions between nutritional factors, fecal and mucosal bacterial flora, and mucosal morphology in patients with a history of pouchitis compared with patients with optimal outcome at least five years after ileal pouch-anal anastomosis for ulcerative colitis. METHODS Thirty-two patients were enrolled in the study: 11 (7 males; mean age, 49.8 years) with optimal outcome and 21 (11 males; mean age, 47.3 years) with pouchitis history. A seven-day food diary was recorded, endoscopy performed, and biopsies taken from the pouch for histology, mucin staining, and bacterial culture. Fresh fecal samples were quantitatively cultured, and fecal bile acids analyzed by gas-liquid chromatography. RESULTS No differences existed in mean nutrient intake, composition of fecal bile acids, or microbial tissue biopsy cultures between the groups with and without pouchitis. Those with optimal outcome tended to have more benign disease course of ulcerative colitis than patients with pouchitis. In those patients, fecal concentrations (log10 colony-forming unit/g) of anaerobes and aerobes were significantly higher (P = 0.007). Degree of villous atrophy and colonic metaplasia were both associated with fecal anaerobic flora. Low intake of lactose was associated with sulfomucin predominance. A negative correlation existed between fecal aerobes and dietary lactose consumption. CONCLUSIONS A higher total load of fecal anaerobic bacterial flora is strongly associated with degree of colonic metaplasia, villous atrophy, and inflammation activity after surgery for ulcerative colitis. An association existed between dietary lactose, fecal bacteria, and pouch morphology. Lactose may have prebiotic properties.

Abstract
Probiotics are living micro-organisms that belong to the normal enteric flora and exert a beneficial effect on health and well-being. The rationale for the therapeutic use of probiotics in pouchitis (the most frequent long-term complication following pouch surgery for ulcerative colitis) and postoperative recurrence in Crohn's disease is based on convincing evidence suggesting a crucial role for the endogenous intestinal microflora in the pathogenesis of these conditions. Positive results have been obtained with the administration of highly concentrated probiotic preparations in preventing the onset and relapses of pouchitis. Further controlled studies are needed to establish the efficacy of probiotics in the prophylaxis of postoperative recurrences of Crohn's disease and in the treatment of mild pouchitis.

Abstract
BACKGROUND Preliminary trials of probiotics in preventing recurrent chronic pouchitis have been encouraging. AIM To investigate the efficacy of Lactobacillus GG supplementation as primary therapy for ileal pouch inflammation, and its effect on the microbial flora. METHODS Twenty patients, with a previous history of pouchitis and endoscopic inflammation, were recruited for a prospective, randomized, double-blind, placebo-controlled trial of Lactobacillus GG supplementation (10 LGG, 10 placebo) in two gelatine capsules [(0.5-1) x 10(10) colony-forming units/capsule] b.d. for 3 months. Quantitative bacterial culture of fresh faecal samples and biopsies taken from the pouch and afferent limb was performed before and after supplementation. RESULTS Lactobacillus GG supplementation changed the pouch intestinal flora by increasing the ratio of total faecal lactobacilli to total faecal anaerobes (P = 0.03) and enhancing the frequency of lactobacilli-positive cultures in the pouch and afferent limb mucosal biopsy samples. However, only 40% of patients were colonized with Lactobacillus GG. No differences were observed between the groups with regard to the mean pouchitis disease activity index or the total anaerobes or aerobes of faecal or tissue biopsy samples. CONCLUSIONS A single-strain probiotic bacterium supplement of Lactobacillus GG changed the pouch intestinal bacterial flora, but was ineffective as primary therapy for a clinical or endoscopic response. More clinical trials are needed to evaluate the right placement and dosage of probiotics within a treatment regimen for pouchitis.

Abstract
PURPOSE Ileal pouch-anal anastomosis is the surgical procedure of choice for selected patients with severe ulcerative colitis. Pouchitis is a common complication of this procedure, with most cases responding to treatment with metronidazole, possibly with the addition of 5-aminosalicylic acid drugs and steroids. can frequently colonize the colon after treatment with broad-spectrum antibiotics, giving rise to diarrhea or colitis. The aim of this report was to describe the first case of -associated diarrhea manifest as pouchitis. METHODS The management of refractory pouchitis in a 35-year-old female with toxin in the stool is described followed by a literature review of small-intestinal infection. RESULTS Assays for toxin on stool sent during an episode considered to be caused by idiopathic chronic pouchitis were positive, and treatment with oral vancomycin was initiated. The patient responded with a reduction in bowel frequency to twice daily, a successful discontinuation of her antidiarrheal medication, and a rapid increase in weight. A subsequent stool assay was negative for the toxin. CONCLUSIONS infection can complicate pouchitis in patients with an ileal pouch-anal anastomosis and should be considered in patients who fail to respond to standard treatment, including metronidazole. In cases of refractory pouchitis, superadded infection with should be excluded before initiation of potent anti-inflammatory drugs.

Abstract
In this chapter we summarize the clinical and experimental data which indicate that bacteria, especially from the endogenous microflora, play a role in the pathogenesis of Crohn's disease, ulcerative colitis and pouchitis. We review the clinical trials, focusing on randomized controlled trials which used antibiotics or probiotics to treat situations of IBD or prevent recurrence, and we discuss the future of this approach.

Abstract
PURPOSE Inflammation is a constant finding in the ileal reservoir of patients with an ileal pouch-anal anastomosis and is associated with decreased fecal concentrations of the short chain fatty acid butyrate, increased fecal pH, changes in fecal flora, and increased concentrations of secondary bile acids. In healthy subjects, inulin, a dietary fiber, is fermented to short chain fatty acids and leads to a lower pH and potentially beneficial changes in fecal flora. The aim of the present study was to investigate the effect of enteral supplementation of inulin on inflammation of the ileal reservoir. METHODS Twenty patients received 24 g of inulin or placebo daily during three weeks in a randomized, double-blind, crossover design. Stools were analyzed after each test period for pH, short chain fatty acids, microflora, and bile acids. Inflammation was assessed endoscopically, histologically, and clinically. RESULTS Compared with placebo, three weeks of dietary supplementation with 24 g of inulin increased butyrate concentrations, lowered pH, decreased numbers of Bacteroides fragilis, and diminished concentrations of secondary bile acids in feces. This was endoscopically and histologically accompanied by a reduction of inflammation of the mucosa of the ileal reservoir. CONCLUSION Enteral inulin supplementation leads to a decrease of inflammation-associated factors and to a reduction of inflammation of pouch mucosa.

Abstract
PURPOSE Ileal pouch-anal anastomosis remains the "gold standard" in surgical treatment of ulcerative colitis and familial adenomatous polyposis. Pouchitis occurs mainly in patients with a background of ulcerative colitis, although the reasons for this are unknown. The aim of this study was to characterize differences in pouch bacterial populations between ulcerative colitis and familial adenomatous pouches. METHODS After ethical approval was obtained, fresh stool samples were collected from patients with ulcerative colitis pouches (n = 10), familial adenomatous polyposis (n = 7) pouches, and ulcerative colitis ileostomies (n = 8). Quantitative measurements of aerobic and anaerobic bacteria were performed. RESULTS Sulfate-reducing bacteria were isolated from 80 percent (n = 8) of ulcerative colitis pouches. Sulfate-reducing bacteria were absent from familial adenomatous polyposis pouches and also from ulcerative colitis ileostomy effluent. Pouch Lactobacilli, Bifidobacterium, Bacteroides sp, and Clostridium perfringens counts were increased relative to ileostomy counts in patients with ulcerative colitis. Total pouch enterococci and coliform counts were also increased relative to ileostomy levels. There were no significant quantitative or qualitative differences between pouch types when these bacteria were evaluated. CONCLUSIONS Sulfate-reducing bacteria are exclusive to patients with a background of ulcerative colitis. Not all ulcerative colitis pouches harbor sulfate-reducing bacteria because two ulcerative colitis pouches in this study were free of the latter. They are not present in familial adenomatous polyposis pouches or in ileostomy effluent collected from patients with ulcerative colitis. Total bacterial counts increase in ulcerative colitis pouches after stoma closure. Levels of Lactobacilli, Bifidobacterium, Bacteroides sp, Clostridium perfringens, enterococci, and coliforms were similar in both pouch groups. Because sulfate-reducing bacteria are specific to ulcerative colitis pouches, they may play a role in the pathogenesis of pouchitis.

Abstract
For PCR specific detection of the strains Bifidobacterium longum Y 10, B. infantis Y 1 and B. breve Y 8 used in a new probiotic product (VSL-3), strains-specific rDNA primers have been developed. Spacer regions between the 16S and 23S rRNA genes (ITS) of the three strains were amplified by PCR with conserved primers and the nucleotide sequence of these ITSs were determined. On the basis of their comparison with the rDNA sequences retrieved from GenBank, we designed new primers which specifically recognize the species B. breve and the two strains B. infantis Y 1 and B. breve Y 8. Specificity of these primers was confirmed through the analysis of 60 bifidobacteria strains belonging to the more representative human species. The feasibility of this PCR method was investigated in commercial VSL-3 product and fecal samples collected from 4 patients affected by inflammatory bowel deseases and two healthy subjects before and after the VSL-3 administration. By PCR analysis of different VSL-3 commercial batches we were successful in differentiating and quantifying the strains B. longum Y 10, B. infantis Y 1 and B. breve Y 8. B. infantis Y 1 and B. breve Y 8 could be detected at high concentration in fecal specimens of both patients and subjects treated with the probiotic preparation, showing a different colonization behaviour. Seven days after the VSL-3 treatment suspension, no patients and subjects harbored B. infantis Y 1 and B. breve Y 8, indicating a transient presence of these exogenous strains.

Abstract
BACKGROUND Pouchitis is the major long-term complication after ileal pouch-anal anastomosis for ulcerative colitis. About 15% of patients have a chronic, treatment-resistant disease. AIMS To evaluate the efficacy of an antibiotic combination for chronic active, treatment-resistant pouchitis. PATIENTS AND METHODS Eighteen patients were treated orally with rifaximin 1 g b.d. + ciprofloxacin 500 mg b.d. for 15 days. Symptoms assessment, endoscopic and histological evaluations were performed at screening and after 15 days using the Pouchitis Disease Activity Index (PDAI). Improvement was defined as a decrease of at least 3 points in PDAI score, and remission as a PDAI score of 0. Systemic absorption of rifaximin was determined by high performance liquid chromatography. Faecal samples were collected before and after antibiotic treatment for stool culture. RESULTS Sixteen out of 18 patients (88.8%) either improved (n=10) or went into remission (n=6); the median PDAI scores before and after therapy were 11 (range 9-17) and 4 (range 0-16), respectively (P < 0.002). No side-effects were reported. Rifaximin plasma levels and urinary excretion were negligible, confirming its mainly topical activity. A significant decrease in total anaerobes and aerobes, enterococci, lactobacilli, bifidobacteria and bacteroides in faecal samples was observed, while the reduction in number of coliforms and Clostridium perfringens did not reach a statistical significance. CONCLUSIONS A combination of rifaximin and ciprofloxacin was effective in patients with active chronic, treatment-resistant pouchitis, suggesting the need, in these patients, for treatment using antibiotic agents with wide antibacterial spectrum of activity.

Abstract
UNLABELLED DEFINITION AND FREQUENCY: An ileoanal anastomosis with creation of an ideal pouch is proposed as the treatment for familial adenomatous polyposis and ulcerative hemorrhagic rectocolitis. The ideal pouch may become inflammatory in 10 to 30% of the cases. The diagnosis of pouchitis is based on a clinical, endoscopid and histological criteria. PATHOGENIC HYPOTHESES Pouchitis is a late complication, mainly after ileoanal anastomosis for ulcerative rectocolitis. The pathogenic mechanism is a subject of debate. Fecal stasis, bacterial pollution, mucine secretion and the underlying inflammatory disease could be involved. TREATMENT Antibiotics active against anaerobic bacteria, such as metronidazole, are generally given. In case of failure, common antiinflammatory agents used in inflammatory bowel disease are indicated.

Abstract
Azoreductase and nitroreductase activities of bacteria in feces of five patients with ileal reservoirs were evaluated, both at the onset of symptoms of pouchitis and following recovery after treatment with drugs. All stool samples tested had bacteria with azoreductase and nitroreductase activities. Azoreductase and nitroreductase activities were higher after recovery than during attacks of pouchitis. During reestablishment of the normal microflora in the ileal reservoirs after pouchitis, the anaerobic bacteria increased and the aerobic bacteria decreased.
