RESUMEN
Fecal Microbiota Transplant (FMT) has shown some success in treating inflammatory bowel diseases (IBD). There is emerging evidence that host engraftment of donor taxa is a tenet of successful FMT. We undertook a double-blind, randomized, placebo-controlled pilot study to characterize the response to FMT in children and young adults with mild to moderate active Crohn's disease (CD) and ulcerative colitis (UC). Subjects with CD or UC were randomized to receive antibiotics and weekly FMT or placebo in addition to baseline medications. We enrolled 15 subjects aged 14-29 years. Four subjects had CD, and 11 had UC. Subjects exhibited a wide range of microbial diversity and donor engraftment. Specifically, engraftment ranged from 26 to 90% at week 2 and 3-92% at 2 months. Consistent with the current literature, increases over time of both alpha diversity (p < 0.05) and donor engraftment (p < 0.05) correlated with improved clinical response. We discovered that the post-antibiotic but pre-FMT time point was rich in microbial correlates of eventual engraftment. Greater residual alpha diversity after antibiotic treatment was positively correlated with engraftment and subsequent clinical response. Interestingly, a transient rise in the relative abundance of Lactobacillus was also positively correlated with engraftment, a finding that we recapitulated with our analysis of another FMT trial.

Fecal microbiota transplantation (FMT) involves the delivery of an entire microbial community from a healthy donor to a recipient with the intention of ameliorating or curing a specific disease. Current evidence strongly supports a role for FMT in the treatment of Clostridiodes difficile infection, with cure rates of approximately 80% to 90%. This success has led to increasing attention for FMT as a potential therapeutic intervention for other conditions associated with disturbances of the intestinal microbiome, including inflammatory bowel diseases, autism spectrum disorder, and obesity. This clinical report endorses the joint society statement by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, and the European Society for Pediatric Gastroenterology, Hepatology and Nutrition and is meant to provide the general pediatrician with a broad overview to enable appropriate guidance to families seeking FMT as treatment of a child's condition.

BACKGROUND: Fecal microbiota transplant (FMT) is an effective treatment for recurrent Clostridioides difficile infection (CDI). Safety concerns around FMT are increased in immunocompromised populations, such as solid organ transplant (SOT) recipients. Outcomes among adult SOT recipients suggest FMT is efficacious and safe; however, pediatric SOT data are lacking. METHODS: We describe the efficacy and safety of FMT among pediatric SOT recipients in a single-center retrospective study from March 2016 to December 2019. Successful FMT was defined as no recurrence of CDI within 2 mo of FMT. We identified 6 SOT recipients ages 4-18 y who received FMT a median of 5.3 y post-SOT. RESULTS: Success after a single FMT was 83.3%. One liver recipient did not achieve cure after 3 FMTs and remains on low-dose vancomycin. One serious adverse event (SAE) occurred; cecal perforation and bacterial peritonitis occurred following colonoscopic FMT coordinated with intestinal biopsy in a kidney transplant recipient. He achieved full recovery and CDI cure. There were no other SAEs. There were no adverse events related to immunosuppression or transplantation status including: bacteremia, cytomegalovirus activation or reactivation, allograft rejection, or allograft loss. CONCLUSIONS: In this limited series, efficacy of FMT in pediatric SOT is comparable to efficacy in the general pediatric recurrent CDI population. There may be an increased risk of procedure-related SAE in SOT patients and larger cohort studies are needed.

With the approval and development of narrow-spectrum antibiotics for the treatment of Clostridioides difficile infection (CDI), the primary endpoint for treatment success of CDI antibiotic treatment trials has shifted from treatment response at end of therapy to sustained response 30 days after completed therapy. The current definition of a successful response to treatment (three or fewer unformed bowel movements [UBMs] per day for 1-2 days) has not been validated, does not reflect CDI management, and could impair assessments for successful treatment at 30 days. We propose new definitions to optimise trial design to assess sustained response. Primarily, we suggest that the initial response at the end of treatment be defined as (1) three or fewer UBMs per day, (2) a reduction in UBMs of more than 50% per day, (3) a decrease in stool volume of more than 75% for those with ostomy, or (4) attainment of bowel movements of Bristol Stool Form Scale types 1-4, on average, by day 2 after completion of primary CDI therapy (ie, assessed on day 11 and day 12 of a 10-day treatment course) and following an investigator determination that CDI treatment can be ceased.

Background: Fecal Microbiota Transplant (FMT) has proven effective in treating recurrent Clostridioides difficile infection (rCDI) and has shown some success in treating inflammatory bowel diseases (IBD). There is emerging evidence that host engraftment of donor taxa is a tenet of successful FMT. However, there is little known regarding predictors of engraftment. We undertook a double-blind, randomized, placebo-controlled pilot study to characterize the response to FMT in children and young adults with mild to moderate active Crohn's disease (CD) and ulcerative colitis (UC). Results: Subjects with CD or UC were randomized to receive antibiotics and weekly FMT or placebo in addition to baseline medications. The treatment arm received seven days of antibiotics followed by FMT enema and then capsules weekly for seven weeks. We enrolled four subjects with CD and 11 with UC, ages 14-29 years. Due to weekly stool sampling, we were able to create a time series of alpha diversity, beta diversity and engraftment as they related to clinical response. Subjects exhibited a wide range of microbial diversity and donor engraftment as FMT progressed. Specifically, engraftment ranged from 26% to 90% at week 2 and 3% to 92% at two months. Consistent with the current literature, increases over time of both alpha diversity (p< 0.05) and donor engraftment (p< 0.05) correlated with improved clinical response. Additionally, our weekly time series enabled an investigation into the clinical and microbial correlates of engraftment at various time points. We discovered that the post-antibiotic but pre-FMT time point, often overlooked in FMT trials, was rich in microbial correlates of eventual engraftment. Greater residual alpha diversity after antibiotic treatment was positively correlated with engraftment and subsequent clinical response. Interestingly, a transient rise in the relative abundance of Lactobacillus was also positively correlated with engraftment, a finding that we recapitulated with our analysis of another FMT trial with publicly available weekly sequencing data. Conclusions: We found that higher residual alpha diversity and Lactobacillus blooms after antibiotic treatment correlated with improved engraftment and clinical response to FMT. Future studies should closely examine the host microbial communities pre-FMT and the impact of antibiotic preconditioning on engraftment and response.
RESUMEN
OBJECTIVES: We sought to evaluate the safety and effectiveness of fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (CDI) in pediatric immunocompromised (IC) patients. METHODS: This is a multicenter retrospective cohort study of pediatric participants who underwent FMT between March 2013 and April 2020 with 12-week follow-up. Pediatric patients were included if they met the definition of IC and were treated with FMT for an indication of recurrent CDI. We excluded patients over 18 years of age, those with incomplete records, insufficient follow-up, or not meeting study definition of IC. We also excluded those treated for Clostridioides difficile recurrence without meeting the study definition and those with inflammatory bowel disease without another immunocompromising condition. RESULTS: Of 59 pediatric patients identified at 9 centers, there were 42 who met inclusion and no exclusion criteria. Included patients had a median age of 6.7 years. Etiology of IC included: solid organ transplantation (18, 43%), malignancy (12, 28%), primary immunodeficiency (10, 24%), or other chronic conditions (2, 5%). Success rate was 79% after first FMT and 86% after 1 or more FMT. There were no statistically significant differences in patient characteristics or procedural components when patients with a failed FMT were compared to those with a successful FMT. There were 15 total serious adverse events (SAEs) in 13 out of 42 (31%) patients that occurred during the follow-up period; 4 (9.5%) of which were likely treatment-related. There were no deaths or infections with multidrug resistant organisms during follow-up and all patients with a SAE fully recovered. CONCLUSIONS: The success rate of FMT for recurrent CDI in this pediatric IC cohort is high and mirrors data for IC adults and immunocompetent children. FMT-related SAEs do occur (9.5%) and highlight the need for careful consideration of risk and benefit.

Fecal microbiota transplantation (FMT) is a rapidly growing therapy aimed at reconstituting the dysbiotic microbiota of a patient with the beneficial stool microbiota of a healthy individual. The efficacy rates of FMT are very robust for recurrent Clostridioides difficile infection in both children and adults. Although complications of FMT have been reported, it is generally believed to be a safe procedure. Novel indications for FMT are being studied, with the hope that ultimately it may be useful for a variety of disorders. As this field continues to grow, however, it is necessary to consider efficacy, safety, and innovation across the lifespan. There are unique concerns regarding FMT as it pertains to children, adults, and the elderly. In this review, we seek to update clinicians, researchers, and regulators on how these factors must be balanced across the lifespan as we move forward with this innovative therapy.

OBJECTIVES: To compare the incidence, epidemiology, testing patterns, treatment, and outcomes of Clostridioides difficile infection (CDI) among hospitalized pediatric patients from 2013 to 2019. STUDY DESIGN: The Pediatric Health Information System database was queried for patient admissions (age 0-17 years) with International Classification of Diseases, 9th and 10th edition, codes for diagnoses of CDI with a billing code for a CDI-related antibiotic treatment. RESULTS: We identified 17â142 pediatric patients, representing 23â052 admissions, with CDI. The adjusted annual CDI incidence decreased over the study period from 7.09 cases per 10â000 patient-days (95% CI, 6.15-8.18) in 2013 to 4.89 cases per 10â000 patient-days (95% CI, 4.03-5.93) in 2019 (P < .001). C difficile-specific testing also decreased during the study period (P < .001). Chronic gastrointestinal conditions (36%) and malignancy (32%) were the most common comorbidities in CDI encounters. Oral metronidazole use decreased during the study period (P < .01) and oral vancomycin use increased (P < .001). CONCLUSIONS: Our study demonstrates a decrease in CDI incidence in hospitalized pediatric patients, a notable change from prior studies, although this may have been influenced by altered testing patterns. We found a high incidence of CDI in patients with cancer and gastrointestinal conditions: groups that warrant targeted evaluation of CDI prevention and treatment.

Increasingly, in the United States, the prescribing of high-cost drugs has become a challenge for physicians and other practitioners. Such drugs are highly regulated by third-party payers (aka insurance), as well as pharmacy benefit managers. Not infrequently, a clinician prescribing a medication will have the payment for the prescription denied by the third-party payer, with the end result being a delay in getting a medically necessary medication to a patient. This article highlights the challenges involved in the prior authorization and denial process, with a focus on pediatric inflammatory bowel disease. The article reviews the role of pharmacy benefits managers in restricting access to drugs, and the reasons why denials of medically necessary medications may occur. The article also provides information on how to appeal denials, how to write a letters of medical necessity, and how to conduct a proper peer-to-peer review. Advocacy from patients and clinicians will be important, as we want to reform the process in the future.

BACKGROUND: Children with inflammatory bowel disease [IBD] are disproportionally affected by recurrent Clostridioides difficile infection [rCDI]. Although faecal microbiota transplantation [FMT] has been used with good efficacy in adults with IBD, little is known about outcomes associated with FMT in paediatric IBD. METHODS: We performed a retrospective review of FMT at 20 paediatric centres in the USA from March 2012 to March 2020. Children with and without IBD were compared with determined differences in the efficacy of FMT for rCDI. In addition, children with IBD with and without a successful outcome were compared with determined predictors of success. Safety data and IBD-specific outcomes were obtained. RESULTS: A total of 396 paediatric patients, including 148 with IBD, were included. Children with IBD were no less likely to have a successful first FMT then the non-IBD affected cohort [76% vs 81%, p = 0.17]. Among children with IBD, patients were more likely to have a successful FMT if they received FMT with fresh stool [p = 0.03], were without diarrhoea prior to FMT [p = 0.03], or had a shorter time from rCDI diagnosis until FMT [p = 0.04]. Children with a failed FMT were more likely to have clinically active IBD post-FMT [p = 0.002] and 19 [13%] patients had an IBD-related hospitalisation in the 3-month follow-up. CONCLUSIONS: Based on the findings from this large US multicentre cohort, the efficacy of FMT for the treatment of rCDI did not differ in children with IBD. Failed FMT among children with IBD was possibly related to the presence of clinically active IBD.

ObjectiveTo examine the relationship between perceived effect of inflammatory bowel diseases (IBD) on high school academics and college planning on college adjustment. Participants: Participants (N = 97) were college students with IBD. Methods: Participants completed an online survey including the Student Adaptation to College Questionnaire and study-developed questions assessing the perceived impact of their diagnosis on their high school academics and college planning. Results: Most participants reported average college adjustment across domains, except personal-emotional adjustment with 47% of participants falling within the very low to low ranges. Nearly half reported IBD impacted their choice of college (49%). The impact of IBD on college planning was most consistently associated with domains of college adjustment. Conclusions: IBD severely impacts college planning, decision-making, and adjustment in college-bound youth. Perceiving that having a chronic illness impacts college planning may result in greater difficulty with academic adjustment, attachment to the institution, and social adjustment during college.

With the rising rates of Clostridioides (Clostridium) difficile infection (CDI) in children, recognizing the limitations of CDI-directed antibiotic therapy, especially in recurrent CDI (rCDI), is important. Fecal microbiota transplantation (FMT), which directly targets the underlying gut dysbiosis present in rCDI, is an important treatment option to consider in rCDI. This article will summarize indications, procedures, effectiveness, and the safety of FMT for rCDI in pediatric patients. [Pediatr Ann. 2021;50(12):e515-e521.].

ABSTRACT: Fecal microbiota transplantation (FMT) is currently the most effective but loosely regulated therapy, for recurrent Clostridioides difficile infection (rCDI) in pediatrics. Over the last 2 years, there have been mounting challenges in the ability to provide FMT to pediatric patients. Firstly, an Food and Drug Administration (FDA) safety alert in 2019 reported transmission of a multidrug resistant organism from FMT donor to recipient resulting in the death of 1 patient. Secondly, the coronavirus disease 2019 (COVID-19) pandemic induced further safety and regulatory challenges. Biotherapeutics are promising and more readily regulated treatment options for rCDI, which may replace FMT in the near future for adults upon regulatory agency approvals. Such approvals, however, are expected to be significantly delayed for children, raising concerns for limited access to effective treatment for children with rCDI. In this commentary, we discuss the recent challenges and future directions of FMT and microbial therapeutics in children with rCDI.

INTRODUCTION: The impact of the 2019 US Food and Drug Administration safety alert involving transmission of multidrug resistant organisms through fecal microbiota transplantation (FMT), and the COVID-19 pandemic on the use of FMT in children, is unknown. METHODS: A survey of pediatric gastroenterologists performing FMT for Clostridioides difficile infection was conducted. RESULTS: Of 36 respondents, 17 (47%) and 30 (83%) changed their FMT practices related to the US Food and Drug Administration safety alert and COVID-19 pandemic, respectively, with 22 (61%) of programs halted. DISCUSSION: The US Food and Drug Administration safety alert and COVID-19 pandemic have substantially influenced the availability and access of FMT for children.

OBJECTIVE: To report experience with fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (rCDI) and provide recommendations for management of rCDI and donor testing during the COVID-19 pandemic. METHODS: A retrospective study of patients with rCDI who underwent FMT from May 26, 2020, to September 30, 2020, with stool from well-screened donors with health and infectious screening and a newly implemented strategy for COVID-19 screening with every 2-week bookend testing with stool quarantine. Patients were followed up for development of rCDI and COVID-19. RESULTS: Of the 57 patients who underwent FMT for rCDI, 29 were tested for COVID-19 via nasopharyngeal polymerase chain reaction (PCR) and 22 via serology. All results were negative, except for 1 positive serology. Donor testing every 2 weeks for COVID-19 via serology and nasopharyngeal swab PCR was negative, except for 2 donors at 1 center who were excluded. Three patients had rCDI after FMT, and 1 underwent repeat FMT. One patient developed respiratory symptoms suggestive of COVID-19 and tested negative via nasopharyngeal PCR. Eleven patients who underwent COVID-19 testing for elective procedures or hospitalizations tested negative. No SARS-CoV-2 transmission was noted. CONCLUSIONS: With appropriate donor screening, FMT can be performed safely for rCDI during the COVID-19 pandemic. Development of a validated stool assay for SARS-CoV-2 will simplify this process further.

Coronavirus disease 2019 is associated with a postinfectious multisystem inflammatory syndrome in children (MIS-C). This syndrome is marked by cytokine storm and multiorgan dysfunction, often affecting the gastrointestinal tract, the heart, and the hematopoietic system. We describe the case of a 16-year-old boy with an initial presentation of severe inflammatory bowel disease and concurrent MIS-C. He presented with abdominal pain, diarrhea, and hematochezia and met criteria for the systemic inflammatory response syndrome. Laboratory inflammatory profiling revealed markedly elevated ferritin, D-dimer, C-reactive protein, soluble interleukin 2, and interleukin 6 levels. Endoscopy and colonoscopy revealed severe active gastroduodenitis, patchy colitis, and a normal-appearing terminal ileum. The patient was treated with a combination of steroids, intravenous immunoglobulin, and infliximab, and his symptoms slowly resolved over a 3-week period. In this case, we describe coincident MIS-C with a remarkably severe and difficult-to-treat initial presentation of inflammatory bowel disease and highlight the need to investigate the effect of coronavirus disease 2019 and MIS-C on inflammatory disorders.
