ABSTRACT
BACKGROUND & AIMS: Acute enteric infections are well known to result in long-term gastrointestinal (GI) disorders. Although COVID-19 is principally a respiratory illness, it demonstrates significant GI tropism, possibly predisposing to prolonged gut manifestations. We aimed to examine the long-term GI impact of hospitalization with COVID-19. METHODS: Nested within a large-scale observational cohort study of patients hospitalized with COVID-19 across North America, we performed a follow-up survey of 530 survivors 12-18 months later to assess for persistent GI symptoms and their severity, and for the development of disorders of gut-brain interaction (DGBIs). Eligible patients were identified at the study site level and surveyed electronically. The survey instrument included the Rome IV Diagnostic Questionnaire for DGBI, a rating scale of 24 COVID-related symptoms, the Gastrointestinal Symptoms Rating Scale, and the Impact of Events-Revised trauma symptom questionnaire (a measure of posttraumatic stress associated with the illness experience). A regression analysis was performed to explore the factors associated with GI symptom severity at follow-up. RESULTS: Of the 530 invited patients, 116 responded (52.6% females; mean age, 55.2 years), and 73 of those (60.3%) met criteria for 1 or more Rome IV DGBI at follow-up, higher than the prevalence in the US general population (P < .0001). Among patients who experienced COVID-related GI symptoms during the index hospitalization (abdominal pain, nausea, vomiting, or diarrhea), 42.1% retained at least 1 of these symptoms at follow-up; in comparison, 89.8% of respondents retained any (GI or non-GI) COVID-related symptom. The number of moderate or severe GI symptoms experienced during the initial COVID-19 illness by self-report correlated with the development of DGBI and severity of GI symptoms at follow-up. Posttraumatic stress disorder (Impact of Events-Revised score ≥33) related to the COVID-19 illness experience was identified in 41.4% of respondents and those individuals had higher DGBI prevalence and GI symptom severity. Regression analysis revealed that higher psychological trauma score (Impact of Events-Revised) was the strongest predictor of GI symptom severity at follow-up. CONCLUSIONS: In this follow-up survey of patients 12-18 months after hospitalization with COVID-19, there was a high prevalence of DGBIs and persistent GI symptoms. Prolonged GI manifestations were associated with the severity of GI symptoms during hospitalization and with the degree of psychological trauma related to the illness experience.
ABSTRACT
INTRODUCTION: Clinical trials have demonstrated the efficacy of FMT for reduction in CDI recurrences (rCDI), but this treatment and its reporting in the literature has significant heterogeneity. Recent publications (e.g., Ramai et al. in Dig Dis Sci 2020. https://doi.org/10.1007/s10620-020-06185-7 ) present the clinical outcomes for different FMT methodologies. However, to understand, compare, and contextualize outcomes, this heterogeneity in methods and reporting must be understood. METHODS: We performed a literature review of randomized controlled trials (RCTs) of FMT for rCDI to evaluate heterogeneity among trials. A methodical search between January 2010 and May 2019 of Medline, Embase, and Cochrane was conducted for studies investigating FMT in adults with rCDI. RCTs were evaluated for a variety of methodological and reporting criteria. RESULTS: Eight RCTs were identified, wherein 14 different FMT preparations were considered (each with distinct protocols for processing, storage, administration, and dosing). Sample sizes were generally small, with only two studies performing FMT in more than 100 patients. Three studies used non-FMT controls (vancomycin), while the remaining compared FMT with differing routes of administration or formulations. Across the identified studies, there was no standardized manner for reporting the timing of the FMT procedure. All studies tracked adverse events; however, follow-up periods were limited. CONCLUSIONS: Considerable variability exists among RCTs, with marked differences in study design, control groups, and outcome assessment. Lack of a standard-of-care control in many trials may impact reproducibility of FMT trial outcomes in patients with rCDI. Widespread use of FMT for rCDI is still investigational; therefore, these foundational studies provide opportunities to optimize future trials.

BACKGROUND AND AIMS: The most common symptoms of Covid-19 are respiratory; however, gastrointestinal symptoms are present in up to 50% of patients. We aimed to determine characteristics associated with the development of gastrointestinal symptoms in patients with Covid-19. METHODS: A case-control study of adults hospitalized for Covid-19 was conducted across a geographically diverse alliance of 36 US and Canadian medical centers. Data were manually abstracted from electronic health records and analyzed using regression analyses to determine characteristics associated with any gastrointestinal symptoms and diarrhea specifically. RESULTS: Of 1406 patients, 540 (38%) reported at least one gastrointestinal symptom and 346 (25%) reported diarrhea. Older patients (≥ 80 years) had significantly lower rates of any gastrointestinal symptoms and diarrhea (vs. patients 18-79 years, OR 0.41, p < 0.01 and OR 0.43 p = 0.01, respectively), while those with IBS (OR 7.70, p = 0.02 and OR 6.72, p < 0.01, respectively) and on immunosuppressive therapy (OR = 1.56, p = 0.02) had higher rates of any gastrointestinal symptom and diarrhea. Patients with constitutional symptoms exhibited significantly higher rates (OR 1.91, p < 0.01), while those with pulmonary disease alone had lower rates of gastrointestinal symptoms (OR 0.23, p = 0.01). A significant interaction between constitutional symptoms and pre-existing pulmonary conditions was observed. CONCLUSIONS: Several patient- and disease-specific characteristics associate with gastrointestinal symptoms in patients with Covid-19. Knowledge of these may provide insights into associated pathophysiologic mechanisms, and help health care professionals provide targeted attention to reduce morbidity related to Covid-19.

INTRODUCTION: Gastroenterologists at all levels of practice benefit from formal mentoring. Much of the current literature on mentoring in gastroenterology is based on expert opinion rather than data. In this study, we aimed to identify gender-related barriers to successful mentoring relationships from the mentor and mentee perspectives. METHODS: A voluntary, web-based survey was distributed to physicians at 20 academic institutions across the United States. Overall, 796 gastroenterology fellows and faculty received the survey link, with 334 physicians responding to the survey (42% response rate), of whom 299 (90%; 129 women and 170 men) completed mentorship questions and were included in analysis. RESULTS: Responses of women and men were compared. Compared with men, more women preferred a mentor of the same gender (38.6% women vs 4.2% men, P < 0.0001) but less often had one (45.5% vs 70.2%, P < 0.0001). Women also reported having more difficulty finding a mentor (44.4% vs 16.0%, P < 0.0001) and more often cited inability to identify a mentor of the same gender as a contributing factor (12.8% vs 0.9%, P = 0.0004). More women mentors felt comfortable advising women mentees about work-life balance (88.3% vs 63.8%, P = 0.0005). Nonetheless, fewer women considered themselves effective mentors (33.3% vs 52.6%, P = 0.03). More women reported feeling pressured to mentor because of their gender (39.5% vs 0.9% of men, P < 0.0001). Despite no gender differences, one-third of respondents reported negative impact of the COVID-19 pandemic on their ability to mentor and be mentored. DISCUSSION: Inequities exist in the experiences of women mentees and mentors in gastroenterology, which may affect career advancement and job satisfaction.

BACKGROUND: Alterations in brain-gut communication and the intestinal microenvironment have been implicated in a variety of medical and neuropsychiatric diseases. Three central areas require basic and clinical research: (1) how the intestinal microenvironment interacts with the host immune system, central nervous system, and enteric nervous system; (2) the role of the intestinal microenvironment in the pathogenesis of medical and neuropsychiatric disease; and (3) the effects of diet, prebiotics, probiotics, and fecal microbiota transplantation on the intestinal microenvironment and the treatment of disease. METHODS: This review article is based on a symposium convened by the American Gastroenterology Association and the American Psychosomatic Society to foster interest in the role of the intestinal microenvironment in brain-gut communication and pathogenesis of neuropsychiatric and biopsychosocial disorders. The aims were to define the state of the art of the current scientific knowledge base and to identify guidelines and future directions for new research in this area. RESULTS: This review provides a characterization of the intestinal microbial composition and function. We also provide evidence for the interactions between the intestinal microbiome, the host, and the environment. The role of the intestinal microbiome in medical and neuropsychiatric diseases is reviewed as well as the treatment effects of manipulation of the intestinal microbiome. CONCLUSIONS: Based on this review, opportunities and challenges for conducting research in the field are described, leading to potential avenues for future research.

Postinfection irritable bowel syndrome (PI-IBS) is a diarrheal disease that develops after infectious gastroenteritis (IGE). Profound alterations in the microbiota accompany IGE yet only 10% of IGE patients progress to PI-IBS. This review explores research linking IGE severity, psychological comorbidity, PI-IBS, and the microbiome in various patient populations. Selective pressures caused by inflammation and increased gastrointestinal motility during gastroenteritis can alter intestinal bacterial phyla including Bacteroidetes, Firmicutes, and Proteobacteria. More specifically, classes such as Bacteroides and Clostridia are differentially abundant in many PI-IBS patients. Altered microbiota may perpetuate a cycle of enteric and systemic inflammation, potently activating neural afferent signaling in the enteric nervous system and causing pain and diarrhea in PI-IBS patients. Altered production of microbial metabolites, for example short chain fatty acids, may have enteric and systemic effects on the host. Longitudinal sampling to characterize changes in the microbiota's genetic, metabolic, and transcriptional activities over time from IGE to PI-IBS may enable improved diagnosis and classification of PI-IBS cases into subtypes, allowing for targeted antibiotic, probiotic, and prebiotic treatments. PI-IBS is a heterogenous and largely organic disease marked by specific alterations in functions of the microbiota and is an important model for studying microbial influences on intestinal, neurological, and psychological host functions.

GOAL: Our aim was to investigate fecal microbiota transplantation (FMT) efficacy in patients with severe and/or complicated Clostridium difficile infection (CDI). BACKGROUND: FMT is successful for recurrent CDI, although its benefit in severe or complicated CDI has not specifically been evaluated. STUDY METHODS: A multicenter long-term follow-up study was performed in patients who received FMT for severe and/or complicated CDI (diagnosed using standard criteria). Pre-FMT and post-FMT questionnaires were completed. Study outcomes included cure rates and time to resolution of symptoms. RESULTS: A total of 17 patients (82% inpatients, 18% outpatients) were included (76.4% women; mean age, 66.4 y; mean follow-up, 11.4 mo). Patients had severe and complicated (76.4%) or either severe or complicated (23.6%) CDI. Sixteen patients (94.1%) had diarrhea, which resolved in 12 (75%; mean time to resolution, 5.7 d) and improved in 4 (25%) after FMT. Eleven patients (64.7%) had abdominal pain, which resolved in 8 (72.7%; mean time to resolution, 9.6 d) and improved in 3 (27.3%) after FMT. Two of 17 patients experienced early CDI recurrence (≤90 d) after FMT (primary cure rate, 88.2%); and in 1 patient, a second FMT resulted in cure (secondary cure rate, 94.1%). Late CDI recurrence (≥90 d) was seen in 1 of 17 patients (5.9%) in association with antibiotics and was successfully treated with a repeat FMT. No adverse effects directly related to FMT occurred. CONCLUSIONS: FMT was successful and safe in this cohort of patients with severe or complicated CDI. Primary and secondary cure rates were 88.2% and 94.1%, respectively.

OBJECTIVES: Clostridium difficile infection (CDI) in the elderly has a higher prevalence, greater morbidity and mortality, and lower response to conventional treatment than the general population. Fecal microbiota transplant (FMT) is highly effective therapy for CDI but has not been studied specifically in the elderly. This study aims to determine the long-term efficacy and safety of FMT for recurrent (RCDI), severe (SCDI), and complicated (CCDI) CDI in elderly patients. METHODS: A multicenter, long-term follow-up study was performed with demographic, pre-FMT, and post-FMT data collected from elderly patients with RCDI, SCDI, and CCDI, through a 47-item questionnaire. Outcome measures included primary and secondary cure rates, early (<12 wk) and late (≥12 wk) recurrence rates, and adverse events (AEs), including post-FMT diagnoses. RESULTS: Of 168 eligible patients, 146 patients met the inclusion criteria. Of these, 68.5% were women. The mean (range) age was 78.6 (65 to 97) years and the follow-up period was 12.3 (1 to 48) months. FMT was performed for RCDI in 89 (61%), SCDI in 45 (30.8%), and CCDI in 12 (8.2%) patients. The primary and secondary cure rates were 82.9% and 95.9%, respectively. Early and late recurrences occurred in 25 and 6 patients, respectively. AEs included CDI-negative diarrhea in 7 (4.8%) and constipation in 4 (2.7%) patients. Serious AEs, recorded in 6 patients, were hospital admissions for CDI-related diarrhea, one of which culminated in death. New diagnoses post-FMT included microscopic colitis (2), Sjogren syndrome (1), follicular lymphoma (1), contact dermatitis and idiopathic Bence-Jones proteinuria (1), and laryngeal carcinoma (1)-all, however, were associated with predisposing factors. CONCLUSIONS: FMT is a safe and effective treatment option for RCDI, SCDI, and CCDI in elderly patients.

PURPOSE OF REVIEW: Fecal microbiota transplantation (FMT) re-establishes a balanced intestinal flora with resultant cure of recurrent Clostridium difficile infection (RCDI). FMT has also been used to treat other gastrointestinal (GI) diseases including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and chronic constipation and a variety of non-GI disorders. The purpose of this review is to discuss the intestinal microbiota and FMT treatment of GI and non-GI diseases. RECENT FINDINGS: It is known that an imbalanced intestinal microbiota predisposes to CDI, IBD and IBS. The complex role of intestinal microbiota to maintain health, however, is a newer concept that is being increasingly studied. The microbiome plays an important role in cellular immunity and energy metabolism and has been implicated in the pathogenesis of non-GI autoimmune diseases, chronic fatigue syndrome, obesity and even some neuropsychiatric disorders. SUMMARY: FMT is a highly effective cure for RCDI, but increased knowledge of the intestinal microbiota in health maintenance, as well as controlled trials of FMT in a wide range of disorders are needed before FMT can be accepted and applied clinically.

BACKGROUND: Irritable bowel syndrome (IBS) is the most prevalent gastrointestinal disorder in developed countries and reduces patients' quality of life, hinders their ability to work, and increases health care costs. A growing number of trials have demonstrated an aberrant gut microbiota composition in IBS, also known as 'gut dysbiosis'. Fecal microbiota transplantation (FMT) has been suggested as a treatment for IBS. AIM: To assess the efficacy and safety of FMT for the treatment of IBS. METHODS: We searched Cochrane Central, MEDLINE, EMBASE and Web of Science up to 24 October 2022 for randomised controlled trials (RCTs) investigating the effectiveness of FMT compared to placebo (including autologous FMT) in treating IBS. The primary outcome was the number of patients with improvements of symptoms measured using a validated, global IBS symptoms score. Secondary outcomes were changes in quality-of-life scores, non-serious and serious adverse events. Risk ratios (RR) and corresponding 95%CI were calculated for dichotomous outcomes, as were the mean differences (MD) and 95%CI for continuous outcomes. The Cochrane risk of bias tool was used to assess the quality of the trials. GRADE criteria were used to assess the overall quality of the evidence. RESULTS: Eight RCTs (484 participants) were included in the review. FMT resulted in no significant benefit in IBS symptoms three months after treatment compared to placebo (RR 1.19, 95%CI: 0.68-2.10). Adverse events were reported in 97 participants in the FMT group and in 45 participants in the placebo group (RR 1.17, 95%CI: 0.63-2.15). One serious adverse event occurred in the FMT group and two in the placebo group (RR 0.42, 95%CI: 0.07-2.60). Endoscopic FMT delivery resulted in a significant improvement in symptoms, while capsules did not. FMT did not improve the quality of life of IBS patients but, instead, appeared to reduce it, albeit non significantly (MD -6.30, 95%CI: -13.39-0.79). The overall quality of the evidence was low due to moderate-high inconsistency, the small number of patients in the studies, and imprecision. CONCLUSION: We found insufficient evidence to support or refute the use of FMT for IBS. Larger trials are needed.

OBJECTIVES: Clostridium difficile infection (CDI) has increased to epidemic proportions over the past 15 years, and recurrence rates of 30-65% with failure to respond to multiple courses of antimicrobials are common. The aim of this study was to report the efficacy of fecal microbiota transplantation (FMT) in patients with recurrent CDI in five geographically disparate medical centers across the United States. METHODS: A multicenter long-term follow-up study was performed on the use of FMT for recurrent CDI. We were able to contact 77 of 94 eligible patients who had colonoscopic FMT for recurrent CDI ≥ 3 months before. Respondents completed a 36-item questionnaire via mail and/or phone that solicited pre-FMT, post-FMT, and donor data. Study outcomes included primary cure rate (resolution of symptoms without recurrence within 90 days of FMT) and secondary cure rate (resolution of symptoms after one further course of vancomycin with or without repeat FMT). RESULTS: Seventy-three percent of patients were women and the average age was 65 years. The long-term follow-up period ranged from 3 to 68 months between FMT and data collection (mean: 17 months). The majority of patients were living independently at the time of FMT; however, 40% were ill enough to be hospitalized, homebound, or living in a skilled nursing facility. Spouses and partners accounted for 60% of donors and 27% were either first-degree relatives or otherwise related to the patient. The average symptom duration before FMT was 11 months and patients had failed an average of five conventional antimicrobial regimens; nonetheless, 74% of patients had resolution of their diarrhea in ≤ 3 days. Diarrhea resolved in 82% and improved in 17% of patients within an average of 5 days after FMT. The primary cure rate was 91%. Seven patients either failed to respond or experienced early CDI recurrence (≤ 90 days) after FMT. Four of these patients were successfully treated with vancomycin with or without probiotics; two patients were treated unsuccessfully with vancomycin, but subsequent FMT was successful; one patient was not treated and died in hospice care of unclear cause. The secondary cure rate was 98%. All late recurrences of CDI occurred in the setting of antimicrobial therapy for treatment of infections unrelated to C. difficile. In all, 53% of patients stated they would have FMT as their preferred first treatment option if CDI were to recur. While no definite adverse effects of FMT were noted, two patients had improvement in a pre-existing medical condition and four patients developed diseases of potential interest after FMT. CONCLUSIONS: FMT is a rational, durable, safe, and acceptable treatment option for patients with recurrent CDI.

Importance: Although health care workers (HCWs) are at higher risk of acquiring coronavirus disease 2019 (COVID-19), it is unclear whether they are at risk of poorer outcomes. Objective: To evaluate the association between HCW status and outcomes among patients hospitalized with COVID-19. Design, Setting, and Participants: This retrospective, observational cohort study included consecutive adult patients hospitalized with a diagnosis of laboratory-confirmed COVID-19 across 36 North American centers from April 15 to June 5, 2020. Data were collected from 1992 patients. Data were analyzed from September 10 to October 1, 2020. Exposures: Data on patient baseline characteristics, comorbidities, presenting symptoms, treatments, and outcomes were collected, including HCW status. Main Outcomes and Measures: The primary outcome was a requirement for mechanical ventilation or death. Multivariable logistic regression was performed to yield adjusted odds ratios (AORs) and 95% CIs for the association between HCW status and COVID-19-related outcomes in a 3:1 propensity score-matched cohort, adjusting for residual confounding after matching. Results: In total, 1790 patients were included, comprising 127 HCWs and 1663 non-HCWs. After 3:1 propensity score matching, 122 HCWs were matched to 366 non-HCWs. Women comprised 71 (58.2%) of matched HCWs and 214 (58.5%) of matched non-HCWs. Matched HCWs had a mean (SD) age of 52 (13) years, whereas matched non-HCWs had a mean (SD) age of 57 (17) years. In the matched cohort, the odds of the primary outcome, mechanical ventilation or death, were not significantly different for HCWs compared with non-HCWs (AOR, 0.60; 95% CI, 0.34-1.04). The HCWs were less likely to require admission to an intensive care unit (AOR, 0.56; 95% CI, 0.34-0.92) and were also less likely to require an admission of 7 days or longer (AOR, 0.53; 95% CI, 0.34-0.83). There were no differences between matched HCWs and non-HCWs in terms of mechanical ventilation (AOR, 0.66; 95% CI, 0.37-1.17), death (AOR, 0.47; 95% CI, 0.18-1.27), or vasopressor requirements (AOR, 0.68; 95% CI, 0.37-1.24). Conclusions and Relevance: In this propensity score-matched multicenter cohort study, HCW status was not associated with poorer outcomes among hospitalized patients with COVID-19 and, in fact, was associated with a shorter length of hospitalization and decreased likelihood of intensive care unit admission. Further research is needed to elucidate the proportion of HCW infections acquired in the workplace and to assess whether HCW type is associated with outcomes.

Background and study aims The coronavirus disease 2019 (COVID-19), and measures taken to mitigate its impact, have profoundly affected the clinical care of gastroenterology patients and the work of endoscopy units. We aimed to describe the clinical care delivered by gastroenterologists and the type of procedures performed during the early to peak period of the pandemic. Methods Endoscopy leaders in the New York region were invited to participate in an electronic survey describing operations and clinical service. Surveys were distributed on April 7, 2020 and responses were collected over the following week. A follow-up survey was distributed on April 20, 2020.âParticipants were asked to report procedure volumes and patient characteristics, as well protocols for staffing and testing for COVID-19. Results Eleven large academic endoscopy units in the New York City region responded to the survey, representing every major hospital system. COVID patients occupied an average of 54.5â% (18â-â84â%) of hospital beds at the time of survey completion, with 14.5â% (2â%-23â%) of COVID patients requiring intensive care. Endoscopy procedure volume and the number of physicians performing procedures declined by 90â% (66â%-98â%) and 84.5â% (50â%-97â%) respectively following introduction of restricted practice. During this period the most common procedures were EGDs (7.9/unit/week; 88â% for bleeding; the remainder for foreign body and feeding tube placement); ERCPs (5/unit/week; for cholangitis in 67â% and obstructive jaundice in 20â%); Colonoscopies (4/unit/week for bleeding in 77â% or colitis in 23â%) and least common were EUS (3/unit/week for tumor biopsies). Of the sites, 44â% performed pre-procedure COVID testing and the proportion of COVID-positive patients undergoing procedures was 4.6â% in the first 2 weeks and up to 19.6â% in the subsequent 2 weeks. The majority of COVID-positive patients undergoing procedures underwent EGD (30.6â% COVIDâ+) and ERCP (10.2â% COVIDâ+). Conclusions COVID-19 has profoundly impacted the operation of endoscopy units in the New York region. Our data show the impact of a restricted emergency practice on endoscopy volumes and the proportion of expected COVID positive cases during the peak time of the pandemic.

BACKGROUND: Colon ischaemia is a common disease which has been associated with various medications and comorbidities. AIM: To test the hypothesis that there are differences in the frequencies of these associations in older compared with younger patients. METHODS: A retrospective cohort study was performed of patients hospitalized with colon ischaemia at two major medical centres from 2005-2017. Clinical, colonoscopic and pathologic criteria were used to identify patients admitted with colon ischaemia; patients with other types of colitis were excluded. Demographic and medical data were extracted. Two cohorts were created: patients aged 18-64 years and patients > 65 years. These were compared using SAS 14.3. RESULTS: A total of 788 patients were included, of which 271 (34.4%) were of ages 18-64 years, and 517 (66.6%) were 65 years old or older. In the older cohort, constipation-inducing medications (83.8% vs 64.1%; P = <0.0001), diuretics (38.1% vs 25.1%; P = <0.001) and nonsteroidal anti-inflammatory drugs (58% vs 41.5%; P = <0.0001) were more common than in the younger cohort. Antipsychotic medication use was more common in the younger cohort (10.4% vs 5.4%; P = 0.01). There was a higher percentage of younger patients with a history of hypercoaguable state (1.9% vs 0.2%; P = 0.03) and dialysis dependence (22.9% vs 8.7%; P = <0.01), while a higher percentage of patients in the older cohort had a history of chronic obstructive pulmonary disease (12% vs 6.3%; P = 0.01) or atrial fibrillation (18.9% vs 10.3%; P = <0.01). CONCLUSIONS: Our study shows that older patients are more likely to have colon ischaemia-associated conditions that are chronic and complex, while younger patients are more likely to have acute colon ischaemia-associated conditions.

BACKGROUND: Faecal microbiota transplantation (FMT) has shown promise in alleviating the symptoms of irritable bowel syndrome (IBS); however, controlled data on this technique are scarce. The aim of this clinical trial was to assess the efficacy of FMT in alleviating diarrhoea-predominant IBS (IBS-D). METHODS: We did a double-blind, randomised, placebo-controlled crossover trial in patients aged 18-65 years with moderate-to-severe IBS-D defined by an IBS-Symptom Severity Score (IBS-SSS) of more than 175, recruited from three US centres. Patients were randomly assigned (1:1) in blocks of four with a computer-generated randomisation sequence to receive FMT capsules followed by identical-appearing placebo capsules, or placebo capsules followed by FMT capsules. All participants and study team members were masked to randomisation. An independent staff member assigned the treatments according to consecutive numbers. Patients received either 75 FMT capsules (each capsule contained approximately 0·38 g of minimally processed donor stool) or 75 placebo capsules over 3 days (25 capsules per day). All patients crossed over to the alternate treatment at 12 weeks. The primary outcome was difference in IBS-SSS between the groups at 12 weeks. Intention-to-treat analyses were done and all patients who received study drug were included in an adverse events analysis. The trial was terminated during recruitment because results from an interim analysis revealed futility. The study is registered with ClinicalTrials.gov, number NCT02328547. FINDINGS: From May 28, 2015, to April 21, 2017, 48 patients were randomly assigned to receive FMT first (n=25) or placebo first (n=23). Three participants were lost to follow-up in the FMT group. IBS-SSS did not differ between FMT recipients (mean 221 [SD 105]) and placebo recipients (236 [95]) at 12 weeks (p=0·65), after adjustment for baseline scores. The most common drug-related adverse events included abdominal pain (five [10%] of the 48 participants while receiving FMT capsules vs four [8%] while receiving placebo), nausea (four [8%] vs two [4%]), and exacerbation of diarrhoea (three [6%] vs eight [17%]). One serious adverse event that was unrelated to study drug (acute cholecystitis) was reported in a patient while receiving placebo capsules. INTERPRETATION: FMT was safe, but did not induce symptom relief at 12 weeks compared with placebo. Additional studies are needed to determine the efficacy of FMT for IBS-D.
