[PMID: 39163678 DOI: 10.1016/j.biopha.2024.117302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Revised: 08/08/2024] [Accepted: 08/13/2024] [Indexed: 08/22/2024] Open
Abstract
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is a complex disorder with an unknown cause. However, the dysbiosis of the gut microbiome has been found to play a role in IBD etiology, including exacerbated immune responses and defective intestinal barrier integrity. The gut microbiome can also be a potential biomarker for several diseases, including IBD. Currently, conventional treatments targeting pro-inflammatory cytokines and pathways in IBD-associated dysbiosis do not yield effective results. Other therapies that directly target the dysbiotic microbiome for effective outcomes are emerging. We review the role of the gut microbiome in health and IBD and its potential as a diagnostic, prognostic, and therapeutic target for IBD. This review also explores emerging therapeutic advancements that target gut microbiome-associated alterations in IBD, such as nanoparticle or encapsulation delivery, fecal microbiota transplantation, nutritional therapies, microbiome/probiotic engineering, phage therapy, mesenchymal stem cells (MSCs), gut proteins, and herbal formulas.

Abstract
The treatment of patients with inflammatory bowel disease (IBD), especially those with severe or refractory disease, represents an important challenge for the clinical gastroenterologist. It seems to be no exaggeration to say that in these patients, not only the scientific background of the gastroenterologist is tested, but also the abundance of "gifts" that he should possess (insight, intuition, determination, ability to take initiative, etc.) for the successful outcome of the treatment. In daily clinical practice, depending on the severity of the attack, IBD is treated with one or a combination of two or more pharmaceutical agents. These combinations include not only the first-line drugs (e.g., mesalazine, corticosteroids, antibiotics, etc) but also second- and third-line drugs (immunosuppressants and biologic agents). It is a fact that despite the significant therapeutic advances there is still a significant percentage of patients who do not satisfactorily respond to the treatment applied. Therefore, a part of these patients are going to surgery. In recent years, several small-size clinical studies, reviews, and case reports have been published combining not only biological agents with other drugs (e.g., immunosuppressants or corticosteroids) but also the combination of two biological agents simultaneously, especially in severe cases. In our opinion, it is at least a strange (and largely unexplained) fact that we often use combinations of drugs in a given patient although studies comparing the simultaneous administration of two or more drugs with monotherapy are very few. As mentioned above, there is a timid tendency in the literature to combine two biological agents in severe cases unresponsive to the applied treatment or patients with severe extraintestinal manifestations. The appropriate dosage, the duration of the administration, the suitable timing for checking the clinical and laboratory outcome, as well as the treatment side-effects, should be the subject of intense clinical research shortly. In this editorial, we attempt to summarize the existing data regarding the already applied combination therapies and to humbly formulate thoughts and suggestions for the future application of the combination treatment of biological agents in a well-defined category of patients. We suggest that the application of biomarkers and artificial intelligence could help in establishing new forms of treatment using the available modern drugs in patients with IBD resistant to treatment.

Abstract
BACKGROUND AND OBJECTIVE Ulcerative colitis (UC) clinical guidelines include the best available evidence, although not all clinical situations are answered, so their management can be controversial. The aim of this study is to identify the situations of mild to moderate UC susceptible to controversy and to evaluate the degree of agreement or disagreement with specific proposals. METHODS Inflammatory bowel disease (IBD) expert discussion meetings were used to identify criteria, attitudes and opinions regarding the management of UC. A Delphi questionnaire was then developed with 60 items regarding antibiotics, salicylates and probiotics; local, systemic and topical corticosteroids; and immunosuppressants. RESULTS Consensus was reached in 44 statements (73.3%); 32 in agreement (53.3%) and 12 in disagreement (20.0%). Some of them were: it is not necessary the systematic use of antibiotics despite the severity of the outbreak, being reserved when there is suspicion of infection or systemic toxicity; when faced with a mild-moderate outbreak of UC and in patients who do not respond to aminosalicylates, it is appropriate to use a dose of beclomethasone of 10mg/day for one month and 5mg/day for another month; it is advised that the dose of azathioprine be administered in a single dose. CONCLUSIONS IBD experts agree on most of the proposals identified for managing mild to moderate UC and there is a need for scientific evidence in some specific situations where expert opinion may be helpful.

Abstract
Inflammatory bowel disease (IBD) is a chronic non-specific inflammatory disease that occurs in the intestinal tract. It is mainly divided into two subtypes, i.e., the Crohn's disease (CD) and ulcerative colitis (UC). At present, its pathogenesis has not been fully elucidated, but it has been generally believed that the environment, immune disorders, genetic susceptibility, and intestinal microbes are the main factors for the disease pathogenesis. With the development of the sequencing technology, microbial factors have received more and more attention. The gut microbiota is in a state of precise balance with the host, in which the host immune system is tolerant to immunogenic antigens produced by gut commensal microbes. In IBD patients, changes in the balance between pathogenic microorganisms and commensal microbes lead to changes in the composition and diversity of gut microbes, and the balance between microorganisms and the host would be disrupted. This new state is defined as dysbiosis. It has been confirmed, in both clinical and experimental settings, that dysbiosis plays an important role in the occurrence and development of IBD, but the causal relationship between dysbiosis and inflammation has not been elucidated. On the other hand, as a classic research method for pathogen identification, the Koch's postulates sets the standard for verifying the role of pathogens in disease. With the further acknowledgment of the disease pathogenesis, it is realized that the traditional Koch's postulates is not applicable to the etiology research (determination) of infectious diseases. Thus, many researchers have carried out more comprehensive and complex elaboration of Koch's postulates to help people better understand and explain disease pathogenesis through the improved Koch's postulates. Therefore, focusing on the new perspective of the improved Koch's postulates is of great significance for deeply understanding the relationship between dysbiosis and IBD. This article has reviewed the studies on dysbiosis in IBD, the use of microbial agents in the treatment of IBD, and their relationship to the modified Koch's postulates.

Abstract
BACKGROUND Antibiotics have been considered to treat ulcerative colitis (UC) due to their antimicrobial properties against intestinal bacteria linked to inflammation. However, there are concerns about their efficacy and safety. OBJECTIVES To determine whether antibiotic therapy is safe and effective for the induction and maintenance of remission in people with UC. SEARCH METHODS We searched five electronic databases on 10 December 2021 for randomised controlled trials (RCTs) comparing antibiotic therapy to placebo or an active comparator. SELECTION CRITERIA We considered people with UC of all ages, treated with antibiotics of any type, dose, and route of administration for inclusion. Induction studies required a minimum duration of two weeks for inclusion. Maintenance studies required a minimum duration of three months to be considered for inclusion. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Our primary outcome for induction studies was failure to achieve remission and for maintenance studies was relapse, as defined by the primary studies. MAIN RESULTS We included 12 RCTs (847 participants). One maintenance of remission study used sole antibiotic therapy compared with 5-aminosalicylic acid (5-ASA). All other trials used concurrent medications or standard care regimens and antibiotics as an adjunct therapy or compared antibiotics with other adjunct therapies to examine the effect on induction of remission. There is high certainty evidence that antibiotics (154/304 participants) compared to placebo (175/304 participants) result in no difference in failure to achieve clinical remission (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.74 to 1.06). A subgroup analysis found no differences when steroids, steroids plus 5-ASA, or steroids plus 5-ASA plus probiotics were used as additional therapies to antibiotics and placebo. There is low certainty evidence that antibiotics (102/168 participants) compared to placebo (121/175 participants) may result in no difference in failure to achieve clinical response (RR 0.75, 95% CI 0.47 to 1.22). A subgroup analysis found no differences when steroids or steroids plus 5-ASA were used as additional therapies to antibiotics and placebo. There is low certainty evidence that antibiotics (6/342 participants) compared to placebo (5/349 participants) may result in no difference in serious adverse events (RR 1.19, 95% CI 0.38 to 3.71). A subgroup analysis found no differences when steroids were additional therapies to antibiotics and placebo. There is low certainty evidence that antibiotics (3/342 participants) compared to placebo (1/349 participants) may result in no difference in withdrawals due to adverse events (RR 2.06, 95% CI 0.27 to 15.72). A subgroup analysis found no differences when steroids or steroids plus 5-ASA were additional therapies to antibiotics and placebo. It is unclear if there is any difference between antibiotics in combination with probiotics compared to no treatment or placebo for failure to achieve clinical remission (RR 0.68, 95% CI 0.39 to 1.19), serious adverse events (RR 1.00, 95% CI 0.07 to 15.08), or withdrawals due to adverse events (RR 1.00, 95% CI 0.07 to 15.08). The certainty of the evidence is very low. It is unclear if there is any difference between antibiotics compared to 5-ASA for failure to achieve clinical remission (RR 2.20, 95% CI 1.17 to 4.14). The certainty of the evidence is very low. It is unclear if there is any difference between antibiotics compared to probiotics for failure to achieve clinical remission (RR 0.47, 95% CI 0.23 to 0.94). The certainty of the evidence is very low. It is unclear if there is any difference between antibiotics compared to 5-ASA for failure to maintain clinical remission (RR 0.71, 95% CI 0.47 to 1.06). The certainty of the evidence is very low. It is unclear if there is any difference between antibiotics compared to no treatment for failure to achieve clinical remission in a mixed population of people with active and inactive disease (RR 0.56, 95% CI 0.29 to 1.07). The certainty of the evidence is very low. For all other outcomes, no effects could be estimated due to a lack of data. AUTHORS' CONCLUSIONS There is high certainty evidence that there is no difference between antibiotics and placebo in the proportion of people who achieve clinical remission at the end of the intervention period. However, there is evidence that there may be a greater proportion of people who achieve clinical remission and probably a greater proportion who achieve clinical response with antibiotics when compared with placebo at 12 months. There may be no difference in serious adverse events or withdrawals due to adverse events between antibiotics and placebo. No clear conclusions can be drawn for any other comparisons. A clear direction for future research appears to be comparisons of antibiotics and placebo (in addition to standard therapies) with longer-term measurement of outcomes. Additionally. As there were single studies of other head-to-head comparisons, there may be scope for future studies in this area.

Abstract
Many clinical trials have been conducted for inflammatory bowel disease (IBD), so various clinical indices (CIs) and endoscopic indices (EIs) have also been evaluated. However, recently, with the progress of IBD management, review of established indices from previous studies, and establishment of new indices, the landscape of the use of indices in clinical trials have changed. We investigated the number and frequency of the indices adapted in recent clinical trials for ulcerative colitis (CI and EI) and Crohn's disease (CI, EI, index related to magnetic resonance imaging, index for evaluating patient-reported outcomes, and health-related quality of life). Based on the results, we selected representative indices and further reviewed their content and characteristics. Moreover, various definitions, including clinical and endoscopic response or remission, have been described by means of representative indices in clinical trials.

Long term impact of vonoprazan-based Helicobacter pylori treatment on gut microbiota and its relation to post-treatment body weight changes. Helicobacter 2021; 26:e12851. [PMID: 34486195 DOI: 10.1111/hel.12851] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 08/24/2021] [Accepted: 08/26/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Vonoprazan-based Helicobacter pylori (H. pylori) treatment is highly effective in eradicating the target bacteria; however, its post-1-year impact on gut microbiota is unknown. This study evaluated the impact of vonoprazan-based H. pylori therapy on gut microbiota 1-year post-therapy and investigated the relationship between body weight changes and post-therapy gut microbiota perturbations. MATERIALS AND METHODS Between March and May 2019, 43 patients with H. pylori infections received either vonoprazan/amoxicillin (VA) or vonoprazan/amoxicillin/clarithromycin (VAC) therapy. Fecal samples were collected prior to treatment and 1 year after treatment. The alpha and beta diversities and the bacterial taxa composition ratios were determined using polymerase chain reaction amplification of the V3-V4 region of the 16S ribosomal RNA gene. The correlation between body weight changes and relative abundances of genera post-therapy was also analyzed. RESULTS Among the 43 patients, 18 received VA therapy and 21 received VAC therapy. One year after treatment, the alpha diversity was significantly higher in both the treatment groups (p < .001, using observed operational taxonomic units and Chao1 index), and beta diversity was significantly different in both the groups (p = .001, using unweighted UniFrac distance) compared with baseline findings. Significant positive correlations were found between body weight changes and the relative abundances of Coprococcus spp. (p = .037) and Odoribacter spp. (p = .022) post-therapy. CONCLUSION Vonoprazan-based H. pylori therapies are associated with long-term impacts on gut microbiota, including effects on bacterial species richness, and potentially affect metabolism by altering the microbiota.

Abstract
Introduction: Current therapies in pediatric Inflammatory Bowel Diseases (IBD) target the immune system and often fail to sustain long-term remission. There is a high need for development of alternative treatment strategies such as antibiotics in pediatric IBD.Areas covered: This study systematically assessed efficacy and safety of antibiotics in pediatric IBD. CENTRAL, EMBASE, and Medline were searched for Randomized Controlled Trials (RCTs). Quality assessment was conducted with the Cochrane risk-of-bias tool.Expert opinion: Two RCTs (n = 101, 4.4-18 years, 43% male) were included. Both studies had overall low risk of bias. In mild-to-moderate Crohn's disease, azithromycin+metronidazole (AZ+MET) (n = 35) compared to metronidazole (MET) alone (n = 38) did not induce a significantly different response (PCDAI drop ≥12.5 or remission) (p = 0.07). For induction of remission (PCDAI≤10), AZ+MET was more effective than MET (p = 0.025). In Acute Severe Colitis, mean 5-day-PUCAI was significantly lower in the antibiotic (vancomycin, amoxicillin, metronidazole, doxycycline)+intravenous-corticosteroids group (AB+IVCS) (n = 16) compared to IVCS alone (n=12) (p = 0.037), whereas remission (PUCAI<10) did not differ (p = 0.61). No significant drug-related adverse events were reported. Results of this systematic review of antibiotic use highlight the lack of evidence in pediatric IBD. More evidence is needed before widespread implementation in daily practice.

GASTROENTEROLOGIA Y HEPATOLOGIA 2021; 43 Suppl 1:1-57. [PMID: 32807301 DOI: 10.1016/j.gastrohep.2020.07.001] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 07/22/2020] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Since the first edition of the Guidelines was published in 2013, much information has been generated around the treatment of ulcerative colitis, and new drugs and action protocols have been introduced. Clinical practice has changed substantially, warranting new approaches and a comprehensive review and update of the evidence. MATERIAL AND METHODS Once again, we used the GRADE approach, supported by an electronic tool (https://gradepro.org). The clinical scenarios are the same as in the previous version (induction and maintenance in severe and mild-moderate flare-ups), as are the variables and their evaluation. However, in the updated guidelines, three questions have been deleted, 14 added and 30 maintained, making a total of 44 clinical questions. After an exhaustive review of the evidence, the recommendations are now updated. RESULTS Of the 44 questions analysed, no recommendation could be established in two due to the very low quality of the evidence, while in the other 42, based on different degrees of quality of evidence, recommendations were made according to the GRADE system. In 25 of these questions the final recommendation is strongly in favour, in six strongly against, in seven weakly in favour and in four weakly against. According to the scenarios and recommendations, six algorithms are proposed as a simple guide for practical decision-making. CONCLUSIONS The aim of this update of the 2013 guidelines is to provide answers, based on the GRADE approach, to the different questions we ask ourselves daily when deciding the most appropriate treatment for our patients with ulcerative colitis in the different clinical scenarios.

Abstract
BACKGROUND Gut microbiota may play a role in the pathogenesis of ulcerative colitis (UC). Antibiotic therapy for patients with UC has shown conflicting results. OBJECTIVES To evaluate the effect of antibiotic therapy in treating UC. METHODS PubMed, EMBASE, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure (CNKI) databases were searched to identify randomized controlled trials (RCTs) that evaluated antibiotics compared with placebo or no antibiotics in patients with UC. We extracted and pooled the risk ratio (RR). RESULTS Twelve RCTs were included in this systematic review and meta-analysis, which included 739 patients with active UC. Antibiotic therapy had statistically significant efficacy in inducing remission rate in patients with UC, observed at the end of trials (random-effect RR = 0.77; 95% confidence interval [CI] 0.60 to 0.98, p = .03) or at 12 months after trials (fixed-effect RR = 0.83; 95% CI 0.73 to 0.94, p = .003). CONCLUSIONS Antibiotic therapy appeared to induce remission more effectively than a placebo or no antibiotic intervention not only in the short-term but also in the long-term for patients with UC. More high-quality clinical trials are needed before clinical recommendations for antibiotic therapy in UC management are made.

Abstract
OBJECTIVES Evaluation of a combination of antibiotics as an adjuvant therapy in acute severe ulcerative colitis (ASUC). METHODS Patients with ASUC were randomized to either infusions of placebo or intravenous ceftriaxone and metronidazole in addition to standard care. Primary outcome was response on day three according to Oxford's criteria. Secondary outcome measures included changes in partial Mayo score, CRP levels, fecal calprotectin (day three), and need for second-line therapy, hospital stay, and mortality (day 28). RESULTS Fifty patients (25 in each group, median age: 33 years, 23 males) were included. The number of patients with fulminant disease in the antibiotic group were 16 (64%) as compared to 7 (28%) in the standard of care group. Complete response on day three was attained by 7 (28%) in the antibiotic and 6 (24%) standard of care group (p = 1.00). Three patients from the antibiotic group underwent colectomy and three received intravenous cyclosporine whereas four patients in the standard of care group received cyclosporine (p = 0.725). There was no significant difference in change in CRP, Partial Mayo score, and fecal calprotectin between the two groups on day three. CONCLUSION Combination of intravenous ceftriaxone and metronidazole did not improve outcomes in ASUC.Acronym: AAASUC trialRegistration Number: CTRI/2019/03/018196 and NCT03794765.

Abstract
BACKGROUND Alterations in the microbiome have been postulated to drive inflammation in IBD. In this pilot randomized controlled trial, we evaluated the effectiveness of quadruple antibiotic cocktail in addition to intravenous-corticosteroids (IVCSs) in acute severe colitis (ASC). METHODS Hospitalized children with ASC (pediatric ulcerative colitis activity index [PUCAI] ≥65) were randomized into 2 arms: the first received antibiotics in addition to IVCS (amoxicillin, vancomycin, metronidazole, doxycycline/ciprofloxacin [IVCS+AB]), whereas the other received only IVCS for 14 days. The primary outcome was disease activity (PUCAI) at day 5. Microbiome was analyzed using 16S rRNA gene and metagenome. RESULTS Twenty-eight children were included: 16 in the AB + IVCS arm and 12 in the IVCS arm (mean age 13.9 ± 4.1 years and 23 [82%] with extensive colitis). The mean day-5 PUCAI was 25 ± 16.7 vs 40.4 ± 20.4, respectively (P = 0.037). Only 3 and 2 children, respectively, required colectomy during 1-year follow-up (P = 0.89). Microbiome data at time of admission were analyzed for 25 children, of whom 17 (68%) had a predominant bacterial species (>33% abundance); response was not associated with the specific species, whereas decreased microbiome diversity at admission was associated with day-5 response in the IVCS arm. CONCLUSION Patients with ASC have alterations in the microbiome characterized by loss of diversity and presence of predominant bacterial species. Quadruple therapy in addition to IVCS improved disease activity on day 5, but larger studies are needed to determine whether this is associated with improved long-term outcomes (clinicaltrials.gov NCT02033408).

Abstract
Gut microbiota constitute the largest reservoir of the human microbiome and are an abundant and stable ecosystem-based on its diversity, complexity, redundancy, and host interactions This ecosystem is indispensable for human development and health. The integrity of the intestinal mucosal barrier depends on its interactions with gut microbiota. The commensal bacterial community is implicated in the pathogenesis of inflammatory bowel disease (IBD), including ulcerative colitis (UC). The dysbiosis of microbes is characterized by reduced biodiversity, abnormal composition of gut microbiota, altered spatial distribution, as well as interactions among microbiota, between different strains of microbiota, and with the host. The defects in microecology, with the related metabolic pathways and molecular mechanisms, play a critical role in the innate immunity of the intestinal mucosa in UC. Fecal microbiota transplantation (FMT) has been used to treat many diseases related to gut microbiota, with the most promising outcome reported in antibiotic-associated diarrhea, followed by IBD. This review evaluated the results of various reports of FMT in UC. The efficacy of FMT remains highly controversial, and needs to be regularized by integrated management, standardization of procedures, and individualization of treatment.

Abstract
Despite the revolution in inflammatory bowel disease (IBD) treatment over the past two decades with the advent of biological therapies, there remains a substantial proportion of patients with inadequate or unsustained response to existent therapies. The overwhelming focus of IBD therapeutics has been targeting mucosal immunity, however with the developing evidence base pointing to the role of gut microbes in the inflammatory process, renewed focus should be placed on the impact of manipulating the microbiome in IBD management. This review provides an overview of the evidence implicating bacteria in the pathogenesis of gut inflammation in IBD and provides an overview of the evidence of antibiotics in IBD treatment. We also suggest a potential role of antibiotics in clinical practice based on available evidence and clinical experience.

Abstract
Despite compelling evidence pointing to a critical role of gut microflora in inflammatory bowel disease (IBD) pathogenesis, the role of antibiotics in clinical practice remains limited, largely due to heterogeneous trials with often conflicting evidence. In this review, we revisit previous randomized controlled trials and high-quality uncontrolled studies in an effort to better elucidate the role of antibiotics in contemporary treatment algorithms. The most established role of antibiotics is in perianal Crohn's disease (CD), utilizing ciprofloxacin with or without metronidazole often as an adjunct to biological therapy. Evidence also points to a likely modest role of various antibiotic classes in mild to moderate luminal CD, including ciprofloxacin, metronidazole, azithromycin, and rifaximin. The benefit of metronidazole in preventing postoperative recurrence in CD is well reported; however, the long-term benefit of this intervention remains uncertain. The use of antibiotics in ulcerative colitis (UC) is even more controversial, but studies using broad-spectrum oral antibiotic cocktails have reported a possible role in acute severe colitis and chronic persistent UC. Similarly, the role of oral vancomycin and gentamicin in very early-onset IBD has interesting preliminary results. Adverse events of antibiotics, the resulting alterations in the microbiome with its associated unknown long-term sequela, and the emergence of antibiotic-resistant strains must be carefully balanced. Therefore, although antibiotics may be underused in the treatment of IBD, their integration into clinical practice must be approached judiciously and individually.

Abstract
Immune checkpoint inhibitors are monoclonal antibodies indicated for an increasing number of malignant diseases. These agents can cause specific side effects, which need to be anticipated while clear patterns of management need to be established. Immune checkpoint inhibitor-mediated gastrointestinal side effects, including diarrhea and colitis, occur in up to 30% of patients. Severe colitis can lead to severe dehydration or intestinal perforation. Endoscopic lesions and histopathological features of immune checkpoint inhibitor-induced colitis are similar to an inflammatory bowel disease (IBD) flare. Patients with immune checkpoint inhibitor-induced diarrhea and colitis are treated with corticosteroids. Infliximab can be used in cases of corticosteroid failure. Rectosigmoïdoscopy or colonoscopy should be performed when severe immune checkpoint inhibitor-induced colitis is suspected, but endoscopic investigations should not delay treatment. Specific patient education as well as co-operation between oncologists and gastroenterologists is essential.

Usefulness of fecal calprotectin for the early prediction of short-term outcomes of remission-induction treatments in ulcerative colitis in comparison with two-item patient-reported outcome. PLoS One 2017; 12:e0185131. [PMID: 28934315 PMCID: PMC5608360 DOI: 10.1371/journal.pone.0185131] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2017] [Accepted: 09/06/2017] [Indexed: 12/22/2022] Open
Abstract
Background Fecal calprotectin (FC) is well accepted as a non-invasive biomarker which objectively reflects colonic inflammation in ulcerative colitis (UC). However, its value as a marker of response during the early phase of remission induction treatment has not been well studied. The aim of this study is to evaluate the significance of FC for predicting the short-term outcomes of remission induction treatment in patients with UC. Methods A prospective observational study was conducted among 31 patients with active UC. FC was monitored with two-item patient-reported outcome (PRO2), partial Mayo score (PMS), and Lichtiger clinical activity index (CAI) during the first 4 weeks of remission induction treatment. Clinical response was defined as a decrease in CAI of 3 or more points below baseline. Mucosal healing (MH) was defined as Mayo endoscopic subscore 0 or 1. Within-day and within-stool variability of FC were assessed during the first week of treatment. Results In week 4-clinical responders, PRO2, PMS, and CAI significantly decreased from day 3, however, FC did not show significant reduction until week 2. Among all markers, the decrease in PRO2 at week 4 most accurately predicted MH at week 12. Within-day variability of FC was remarkably wide even at the first week in clinical responders. Within-stool variability was extremely small. Conclusions PRO2 predicted the short-term outcomes of remission induction treatment earlier than FC possibly because of the wide within-day variability of FC in active UC.

Abstract
BACKGROUND In recent years, especially after the development of sophisticated metagenomic studies, research on the intestinal microbiota has increased, radically transforming our knowledge about the microbiome and its association with health maintenance and disease development in humans. Increasing evidence has shown that a permanent alteration in microbiota composition or function (dysbiosis) can alter immune responses, metabolism, intestinal permeability, and digestive motility, thereby promoting a proinflammatory state. Such alterations can mainly impair the host's immune and metabolic functions, thus favoring the onset of diseases such as diabetes, obesity, digestive, neurological, autoimmune, and neoplastic diseases. This comprehensive review is a compilation of the available literature on the formation of the complex intestinal ecosystem and its impact on the incidence of diseases such as obesity, non-alcoholic steatohepatitis, irritable bowel syndrome, inflammatory bowel disease, celiac disease, and digestive neoplasms. CONCLUSION: Alterations in the composition and function of the gastrointestinal microbiota (dysbiosis) have a direct impact on human health and seem to have an important role in the pathogenesis of several gastrointestinal diseases, whether inflammatory, metabolic, or neoplastic ones.

Abstract
BACKGROUND & AIMS The paradigm for treatment for ulcerative colitis (UC) is shifting from resolving symptoms toward objective measures such as mucosal healing (MH). However, it is unclear whether MH is associated with improved long-term outcomes. We performed a systematic review and meta-analysis to identify and analyze studies comparing long-term outcomes of patients with MH with those without MH. METHODS We performed a systematic search of 3 large databases to identify prospective studies of patients with active UC that included outcomes of patients found to have MH at the first endoscopic evaluation after initiation of UC therapy (MH1) compared with those without MH1. The primary outcome was clinical remission after at least 52 weeks. Secondary outcomes included proportions of patients who were free of colectomy or corticosteroids and rate of MH after at least 52 weeks. RESULTS We analyzed 13 studies comprising 2073 patients with active UC. Patients with MH1 had pooled odds ratio of 4.50 for achieving long-term (after at least 52 weeks) clinical remission (95% confidence interval [CI], 2.12-9.52), 4.15 for remaining free of colectomy (95% CI, 2.53-6.81), 8.40 for achieving long-term MH (95% CI, 3.13-22.53), and 9.70 for achieving long-term corticosteroid-free clinical remission (95% CI, 0.94-99.67), compared with patients without MH1. We found no difference in outcomes if patients achieved MH1 while receiving biologic versus non-biologic therapy. CONCLUSIONS In a meta-analysis, we associated MH with long-term clinical remission, avoidance of colectomy, and corticosteroid-free clinical remission. MH is therefore appropriate goal of UC therapy.

Abstract
Inflammatory bowel disease is thought to be caused by an aberrant immune response to gut bacteria in a genetically susceptible host. The gut microbiota plays an important role in the pathogenesis and complications of the two main inflammatory bowel diseases: Crohn’s disease (CD) and ulcerative colitis. Alterations in gut microbiota, and specifically reduced intestinal microbial diversity, have been found to be associated with chronic gut inflammation in these disorders. Specific bacterial pathogens, such as virulent Escherichia coli strains, Bacteroides spp, and Mycobacterium avium subspecies paratuberculosis, have been linked to the pathogenesis of inflammatory bowel disease. Antibiotics may influence the course of these diseases by decreasing concentrations of bacteria in the gut lumen and altering the composition of intestinal microbiota. Different antibiotics, including ciprofloxacin, metronidazole, the combination of both, rifaximin, and anti-tuberculous regimens have been evaluated in clinical trials for the treatment of inflammatory bowel disease. For the treatment of active luminal CD, antibiotics may have a modest effect in decreasing disease activity and achieving remission, and are more effective in patients with disease involving the colon. Rifamixin, a non absorbable rifamycin has shown promising results. Treatment of suppurative complications of CD such as abscesses and fistulas, includes drainage and antibiotic therapy, most often ciprofloxacin, metronidazole, or a combination of both. Antibiotics might also play a role in maintenance of remission and prevention of post operative recurrence of CD. Data is more sparse for ulcerative colitis, and mostly consists of small trials evaluating ciprofloxacin, metronidazole and rifaximin. Most trials did not show a benefit for the treatment of active ulcerative colitis with antibiotics, though 2 meta-analyses concluded that antibiotic therapy is associated with a modest improvement in clinical symptoms. Antibiotics show a clinical benefit when used for the treatment of pouchitis. The downsides of antibiotic treatment, especially with recurrent or prolonged courses such as used in inflammatory bowel disease, are significant side effects that often cause intolerance to treatment, Clostridium dificile infection, and increasing antibiotic resistance. More studies are needed to define the exact role of antibiotics in inflammatory bowel diseases.

Abstract
BACKGROUND Gut microbiota dysbiosis contributes to the pathogenesis of inflammatory bowel diseases (IBD). Although the microbiota's role in IBD pathogenesis, specifically Crohn's disease (CD), provides a rationale for antibiotic treatment, antibiotic use in CD remains controversial. Rifaximin, traditionally identified as a nonsystemic bactericidal antibiotic, may be therapeutically beneficial for inducing CD remission. AIM To examine the role of rifaximin in the management of IBD and its potential mechanisms of action. METHODS A literature search using the following strategy: ('inflammatory bowel disease' OR 'Crohn's' OR 'ulcerative'), 'rifaximin' AND ('barrier' OR 'translocation' OR 'adhesion' OR 'internalization' OR 'pregnane X'), AND 'pregnane X' AND ('Crohn's' OR 'ulcerative colitis' OR 'inflammatory bowel disease'). RESULTS In vitro data suggest rifaximin mediates changes in epithelial cell physiology and reduces bacterial attachment and internalisation. In experimental colitis models, rifaximin antagonised the effects of tumour necrosis factor-α on intestinal epithelial cells by activating pregnane X receptor, which inhibits nuclear factor-κB-mediated proinflammatory mediators and induces detoxification genes (e.g. multidrug resistance 1 and cytochrome P450 3A4). Rifaximin also inhibits bacterial translocation into the mesenteric lymph nodes. CONCLUSION Accumulating evidence suggests that mechanisms of action of rifaximin in IBD may not be limited to direct bactericidal activity; therefore, rifaximin could potentially be redefined as a gut environment modulator.

Abstract
Immunomodulatory antibiotics have been proposed for the treatment of multifactorial conditions such as inflammatory bowel disease. Probiotics are able to attenuate intestinal inflammation, being considered as safe when chronically administered. The aim of the study was to evaluate the anti-inflammatory effects of doxycycline, a tetracycline with immunomodulatory properties, alone and in association with the probiotic Saccharomyces boulardii CNCMI-745. Doxycycline was assayed both in vitro (Caco-2 epithelial cells and RAW 264.7 macrophages) and in vivo, in the trinitrobenzenesulfonic acid (TNBS) model of rat colitis and the dextran sodium sulfate (DSS) model of mouse colitis. In addition, the anti-inflammatory effect of the association of doxycycline and the probiotic was evaluated in vitro and in vivo in a DSS model of reactivated colitis in mice. Doxycycline displayed immunomodulatory activity in vitro, reducing IL-8 production by intestinal epithelial cells and nitric oxide by macrophages. Doxycycline administration to TNBS-colitic rats (5, 10 and 25 mg/kg) ameliorated the intestinal inflammatory process, being its efficacy comparable to that previously showed by minocycline. Doxycycline treatment was also effective in reducing acute intestinal inflammation in the DSS model of mouse colitis. The association of doxycycline and S. boulardii helped managing colitis in a reactivated model of colitis, by reducing intestinal inflammation and accelerating the recovery and attenuating the relapse. This was evidenced by a reduced disease activity index, colonic tissue damage and expression of inflammatory mediators. This study confirms the intestinal anti-inflammatory activity of doxycycline and supports the potential use of its therapeutic association with S. boulardii for the treatment of inflammatory bowel diseases, in which doxycycline is used to induce remission and long term probiotic administration helps to prevent the relapses.

Abstract
Over the past recent years, a great number of studies have been directed toward the evaluation of the human host-gut microbiota interaction, with the goal to progress the understanding of the etiology of several complex diseases. Alterations in the intestinal microbiota associated with inflammatory bowel disease are well supported by literature data and have been widely accepted by the research community. The concomitant implementation of high-throughput sequencing techniques to analyze and characterize the composition of the intestinal microbiota has reinforced the view that inflammatory bowel disease results from altered interactions between gut microbes and the mucosal immune system and has raised the possibility that some form of modulation of the intestinal microbiota may constitute a potential therapeutic basis for the disease. The aim of this review is to describe the changes of gut microbiota in inflammatory bowel disease, focusing the attention on its involvement in the pathogenesis of the disease, and to review and discuss the therapeutic potential to modify the intestinal microbial population with antibiotics, probiotics, prebiotics, synbiotics and fecal microbiota transplantation.
