BACKGROUND: The gut microbiota is strongly associated with radiation-induced gut damage. This study aimed to assess the effectiveness and safety of intestinal microecological transplantation for treating patients with chronic radiation enteritis. CASE SUMMARY: A 64-year-old female with cervical cancer developed abdominal pain, diarrhea, and blood in the stool 1 year after radiotherapy. An electronic colonoscopy was performed to diagnose chronic radiation enteritis. Two courses of intestinal microecological transplantation and full-length 16S rRNA microbiological analysis were performed. The patient experienced short- and long-term relief from symptoms without adverse effects. Whole 16S rRNA sequencing revealed significant differences in the intestinal flora's composition between patient and healthy donors. Pathogenic bacteria, such as Escherichia fergusonii and Romboutsia timonensis, were more in the patient. Beneficial bacteria such as Faecalibacterium prausnitzii, Fusicatenibacter saccharivorans, Ruminococcus bromii, and Bifidobacterium longum were more in the healthy donors. Intestinal microbiota transplantation resulted in a significant change in the patient's intestinal flora composition. The composition converged with the donor's flora, with an increase in core beneficial intestinal bacteria, such as Eubacterium rectale, and a decrease in pathogenic bacteria. Changes in the intestinal flora corresponded with the patients' alleviating clinical symptoms. CONCLUSION: Intestinal microecological transplantation is an effective treatment for relieving the clinical symptoms of chronic radiation enteritis by altering the composition of the intestinal flora. This study provides a new approach for treating patients with chronic radiation enteritis.

Endoscopic evaluation with biopsies is a mainstay of the diagnosis of eosinophilic esophagitis (EoE) and non-EoE eosinophilic gastrointestinal diseases (EGIDs). Increasing knowledge has resulted in the development of 2 standardized scoring systems: the Endoscopic REFerence Score (EREFS) for EoE and the EG-REFS for eosinophilic gastritis, although the latter has not been validated. In EGIDs, diagnosis and follow-up focus on eosinophil infiltration in biopsies. In this article, we will discuss the most commonly used endoscopic scores in EoE and non-EoE EGIDs, their validity for the diagnosis and follow-up of disease activity, as well as endoscopic interventions and areas of uncertainty.

Eosinophilic gastrointestinal diseases (EGID), such as eosinophilic gastritis (EoG), eosinophilic enteritis, and eosinophilic colitis (EoC), are chronic inflammatory conditions characterized by persistent gastrointestinal symptoms and elevated levels of activated eosinophils in the gastrointestinal tract. EoG and eosinophilic duodenitis (EoD) are strongly associated with food allergen triggers and TH2 inflammation, whereas EoC shows minimal transcriptomic overlap with other EGIDs. The level of expression of certain genes associated with TH2 immune response is associated with certain histopathologic findings of EoG, EoD, and EoC. Current immune therapy for EoG depletes tissue eosinophilia with persistence of other histopathologic features of disease.

Patients with non-eosinophilic esophagitis eosinophilic gastrointestinal diseases (non-EoE EGIDs) are prone to nutritional deficiencies due to food-avoidant behaviors, malabsorption, and high nutrition impact symptoms. Nutrient deficiencies correspond to the segment, depth, and extent of the gastrointestinal tract involved and can impact organs distant from the gut. Patients with non-EoE EGIDs are often atopic, and some appear to respond to dietary avoidance of specific food allergens. Tests to identify food triggers other than response to elimination diets are lacking. Dietary restriction therapy should be considered in such patients and is best implemented through a multidisciplinary approach to avoid nutritional complications.

The clinical presentation of eosinophilic gastrointestinal diseases beyond eosinophilic esophagitis (non-EoE EGIDs) varies depending on the gastrointestinal segments affected by the eosinophilic inflammation, the extent of eosinophilic inflammation within the gastrointestinal tract and its depth through the bowel wall. Non-EoE EGIDs with mucosal involvement tend to present with diarrhea, malabsorption, and sometimes bleeding, those with muscular involvement may present with symptoms of obstruction or pseudo-obstruction, intussusception, and even perforation, whereas those with serosal involvement may present with eosinophilic ascites. Here we describe the differences in symptoms experienced by children with non-EoE EGIDs with varying degrees of eosinophilic inflammation through the bowel wall.

Mast cells play a central role in the pathogenesis of eosinophilic gastrointestinal disorders (EGIDs), including eosinophilic esophagitis. Their interactions with immune and structural cells, involvement in tissue remodeling, and contribution to symptoms make them attractive targets for therapeutic intervention. More is being discovered regarding the intricate interplay of mast cells and eosinophils. Recent studies demonstrating that depletion of eosinophils is insufficient to improve symptoms of EGIDs have raised the question of whether other cells may play a role in symptomatology and pathogenesis of EGIDs.

Eosinophilic gastrointestinal disorder (EGID) is an umbrella term encompassing a group of chronic, immune-mediated disorders characterized by eosinophil-rich inflammation affecting one or more segments of the gastrointestinal tract. A recent consensus in nomenclature and emerging data made possible through multi-center consortia are beginning to unravel the molecular and cellular underpinnings of EGIDs below the esophagus. These emerging findings are revealing both overarching commonalities related to a food allergen-driven, chronic, Th2-mediated immune response as well as location-specific nuances in the pathophysiology of the collective EGIDs. Altogether, these advances offer promise for improved diagnoses and more efficacious interventional strategies.

Radiation enteritis is a common complication of abdominal and pelvic radiotherapy. Several previous studies showed that fecal microbiota transplantation (FMT) could alleviate radiation enteritis. In this study, we investigated the efficacy of FMT in alleviating radiation enteritis and explored the mechanisms by multi-omics approaches. Briefly, C57BL/6J mice were subjected to 9 Gy irradiation to the localized abdominal field, and randomized received FMT from healthy donor mice or saline. H&E staining of harvested small intestine showed FMT decreased epithelial injury. Radiation-induced microbiota dysbiosis, characterized by a decrease in beneficial bacteria Lactobacillaceae and Lachnospiraceae, while these bacteria were restored by FMT. Fecal metabolomics analysis revealed that FMT modulated metabolic dysregulation. Two tryptophan pathway metabolites, indole-3-acetaldehyde and N-Acetyl-5-hydroxytryptamine were decreased after irradiation, whereas these metabolites showed a pronounced recovery in mice receiving FMT. Proteomics analysis of small intestine indicated that radiation enteritis triggered immune-inflammatory responses, which were potentially mitigated by FMT. In 21 patients receiving pelvic radiotherapy for cervical cancer, those who developed enteritis (n = 15) had higher abundance in Lachnospiraceae. Moreover, Indole-3-acetaldehyde was reduced after irradiation. These findings provide insights into the therapeutic effects of FMT in radiation enteritis and highlight Lachnospiraceae and the tryptophan metabolite, Indole-3-acetaldehyde may protect against radiation enteritis.

The purpose of this study was to investigate the role of Lactobacillus rhamnosus GG (LGG) probiotics in radiation enteritis using in vivo mice. A total of 40 mice were randomly assigned to four groups: control, probiotics, radiotherapy (RT), and RT + probiotics. For the group of probiotics, 0.2 mL of solution that contained 1.0 × 108 colony-forming units (CFU) of LGG was used and orally administered daily until sacrifice. For RT, a single dose of 14 Gy was administered using a 6 mega-voltage photon beam to the abdominopelvic area. Mice were sacrifice at day 4 (S1) and day 7 (S2) after RT. Their jejunum, colon, and stool were collected. A multiplex cytokine assay and 16 s ribosomal RNA amplicon sequencing were then performed. Regarding cytokine concentrations in tissues, pro-inflammatory cytokines, such as tumor necrosis factor-α, interleukin-6 and monocyte chemotactic protein-1, showed significantly decreased protein levels in colon tissues of the RT + probiotics group than in the RT alone group (all p < 0.05). As for comparing microbial abundance through alpha-diversity and beta-diversity, no significant differences were observed between the RT + probiotics and RT alone groups, except for an increase in alpha-diversity in the stool of the RT + probiotics group. Upon analysis of differential microbes based on treatment, the dominance of anti-inflammatory-related microbes, such as Porphyromonadaceae, Bacteroides acidifaciens, and Ruminococcus, was observed in the jejunum, colon, and stool of the RT + probiotics group. With regard to predicted metabolic pathway abundances, the pathways associated with anti-inflammatory processes, such as biosynthesis of pyrimidine nucleotides, peptidoglycans, tryptophan, adenosylcobalamin, and propionate, were differentially identified in the RT + probiotics group compared to the RT alone group. Protective effects of probiotics on radiation enteritis were potentially derived from dominant anti-inflammation-related microbes and metabolites.

Although eosinophilic gastrointestinal diseases, including eosinophilic esophagitis, have been described over the past 2 to 3 decades, barriers to diagnosis and treatment are common and compounded by issues related to social determinants of health, race, ethnicity, and access to care. These barriers contribute to delays in diagnosis, resulting in persistent inflammation in the gastrointestinal tract, which can have significant consequences, including fibrostenotic complications in adults, failure to thrive in children, and decreased quality of life in all affected patients. In this commentary, we summarize gaps in knowledge regarding the epidemiology of eosinophilic gastrointestinal diseases, highlight barriers to diagnosis, discuss potential approaches based on best practices in other atopic and chronic gastrointestinal diseases, and provide recommendations for reducing barriers to timely diagnosis of eosinophilic gastrointestinal diseases in underserved populations.

Objective: To explore the short-term efficacy of perioperative fecal microbiota transplantation combined with nutritional support in patients with radiation-induced enteritis complicated by intestinal obstruction. Methods: The cohort of this prospective cohort study comprised 45 patients (nine men and 36 women) with radiation-induced enteritis complicated by intestinal obstruction admitted to Shanghai Tenth People's Hospital Affiliated to Tongji University from January 2022 to October 2022. The median age was 53 (42-65) years. Thirty-five of the patients had gynecological tumors and 10 colorectal malignancies. The patients were randomly allocated to a fecal microbiota transplantation group of 20 patients who underwent fecal microbiota transplantation starting 2 weeks before surgery for 6 days, in addition to receiving conventional perioperative treatment, and a conventional treatment group of 25 patients who only received nutritional support during the perioperative period. There were no significant differences in baseline characteristics (sex, age, preoperative nutritional indices, and surgical procedure) between the two groups (all P>0.05). Postoperative recovery (time to passing flatus or a bowel movement, length of stay) and complications were compared between the two groups. Postoperative complications within 30 days after surgery classified in accordance with the international Clavien-Dindo classification of surgical complications (I-V) were statistically analyzed. Improvement in gastrointestinal symptoms, namely abdominal pain, distension, diarrhea, and rectal bleeding) and gastrointestinal quality of life scores (which include 36 problems rated 0-144 points related to physical, psychological, social activities and family life; the lower the score, the more severe the symptoms) were compared between the two groups. Nutritional recovery was assessed by body mass, body mass index, total protein, albumin, prealbumin, and hemoglobin. Results: Compared with the conventional treatment group, the postoperative hospital stay was shorter in the fecal microbiota transplantation group (8.0±4.3 days vs. 11.2±5.4 days, t=2.157, P=0.037) and the time to passage of flatus or having a bowel movement was earlier (2.2±3.2 days vs. 3.9±2.3 days, t=2.072, P=0.044). There were 26 postoperative complications in the fecal microbiota transplantation group and 59 in the conventional treatment group. There were 20 and 36 Grade I to II complications and no and three Grade III to V complications in the transplantation and conventional treatment group, respectively. The overall grade of complication did not differ significantly between the two groups (P=0.544). However, the incidence of postoperative intestinal inflammatory obstruction was lower in the fecal microbiota transplantation than the conventional treatment group (10.0% [2/20] vs. 40.0% [10/25], P=0.040). One patient in the conventional treatment group died. This patient had complete intestinal obstruction complicated by severe malnutrition preoperatively, and an intestinal fistula complicated by abdominal infection postoperatively, and died despite active treatment. Nineteen and 23 patients in the transplantation and conventional treatment group, respectively, attended for follow-up 1 month after surgery; 19 and 21, respectively, attended for follow-up 3 months after surgery, and 17 and 20, respectively, attended for follow-up 6 months after surgery. There were no significant differences between the two groups in abdominal pain or rectal bleeding 1, 3, or 6 months after surgery (all P>0.05). One month after surgery, the incidence of abdominal distension and diarrhea was lower in the fecal microbiota transplantation than in the conventional treatment group (3/19 vs. 48.0% [11/23], P=0.048; 3/19 vs. 52.2% [12/23], P=0.023). However, at the 3 and 6 month follow-ups the incidence of abdominal distension and diarrhea had gradually decreased in both groups and the differences between the groups were not statistically significant (P>0.05 for all). Scores for gastrointestinal quality of life improved significantly in both treatment groups compared with preoperative values (F=71.250, P<0.001; F=79.130, P<0.001, respectively). Scores for gastrointestinal quality of life were higher in the fecal microbiota transplantation than the conventional treatment group at all follow-up time points (P<0.05). One-way ANOVA showed that body mass, body mass index, and total protein, albumin and hemoglobin concentrations improved in both groups compared with preoperative values (all P<0.05). Prealbumin concentration improved significantly in the transplantation (F=5.514, P=0.002), but not in the conventional, group (F=1.535, P=0.211). The improvements in body mass, body mass index, total protein, and albumin were better in the fecal microbiota transplantation than conventional treatment group at 3 and 6 months of follow-up (all P<0.05). Conclusion: Perioperative fecal microbiota transplantation combined with nutritional support is effective in improving early postoperative nutritional status and quality of life in patients with radiation-induced enteritis complicated by intestinal obstruction.

Eosinophilic gastrointestinal disorders are a group of rare diseases characterized by the infiltration of eosinophils in the gastrointestinal wall in a greater amount than in homeostatic conditions. 'Non-esophageal eosinophilic gastrointestinal disorders' is the umbrella term for all eosinophilic gastrointestinal disorders outside of the well known eosinophilic esophagitis. This includes eosinophilic gastritis, eosinophilic enteritis and eosinophilic colitis. The clinical presentation is atypical and not very different for the three disorders. The depth of infiltration has a bigger influence on the presenting symptoms than the disease location. Although the frequency of diagnosis and research in this subject is increasing over time, non-esophageal eosinophilic disorders are rare and high quality evidence is limited to date. In this narrative review, we provide an overview of the latest insights in the pathophysiology, diagnostic approach and available treatment options. Transcriptome studies have found the pathogenesis to be T helper type 2 driven. Various laboratory findings can be used to trigger raised suspicion and investigation with endoscopy. As the endoscopic appearance of the mucosa is normal in most cases, multiple biopsies in each segment are needed to quantify the amount of eosinophils in the tissue. Eosinophilic cut-offs for diagnosis are a controversial topic and a consensus is still lacking. A recently developed tissue based diagnostic platform which measures differentially expressed genes might be available in the future to classify patients with intermediate eosinophilic tissue levels under the cut-off. For the treatment, corticosteroids are still the cornerstone of treatment but promising research suggests a role of biologicals, such as Lirentelimab (anti-siglec 8) in particular.

BACKGROUND: Radiation enteritis (RE) is a common complication of abdominal or pelvic radiotherapy, which when severe, could be life-threatening. Currently, there are no effective treatments. Studies have shown that mesenchymal stem cells (MSCs)-derived exosomes (MSC-exos) exhibit promising therapeutic effects in inflammatory diseases. However, the specific role of MSC-exos in RE and the regulatory mechanisms remain elusive. METHODS: In vivo assay was carried out by injecting MSC-exos into the total abdominal irradiation (TAI)-induced RE mouse model. For in vitro assay, Lgr5-positive intestinal epithelial stem cells (Lgr5+ IESC) were extracted from mice, followed by irradiation along with MSC-exos treatment. HE staining was performed to measure histopathological changes. mRNA expression of inflammatory factors TNF-α and IL-6 and stem cell markers LGR5, and OCT4 were quantified by RT-qPCR. EdU and TUNEL staining was performed to estimate cell proliferation and apoptosis. MiR-195 expression in TAI mice and radiation-induced Lgr5+ IESC was tested. RESULTS: We found that the injection of MSC-exos inhibited inflammatory reaction, increased stem cell marker expression, and maintained intestinal epithelial integrity in TAI mice. Furthermore, MSC-exos treatment increased the proliferation and simultaneously suppressed apoptosis in radiation-stimulated Lgr5+ IESC. MiR-195 expression increased by radiation exposure was decreased by MSC-exos therapy. MiR-195 overexpression facilitated the progress of RE by counteracting the effect of MSC-exos. Mechanistically, the Akt and Wnt/ß-catenin pathways inhibited by MSC-exos were activated by miR-195 upregulation. CONCLUSION: MSC-Exos are effective in treating RE and are essential for the proliferation and differentiation of Lgr5+ IESCs. Moreover, MSC-exos mediates its function by regulating miR-195 Akt ß-catenin pathways.
