Long COVID is estimated to have affected 6.9 % of US adults, 17.8 million people in the US alone, as of early 2023. While SARS-CoV-2 is primarily considered a respiratory virus, gastrointestinal (GI) symptoms are also frequent in patients with coronavirus disease 2019 (COVID-19) and in patients with Long COVID. The risk of developing GI symptoms is increased with increasing severity of COVID-19, the presence of GI symptoms in the acute infection, and psychological distress both before and after COVID-19. Persistence of the virus in the GI tract, ensuing inflammation, and alteration of the microbiome are all likely mediators of the effects of SARS Co-V-2 virus on the gut. These factors may all increase intestinal permeability and systemic inflammation. GI inflammation and dysbiosis can change the absorption and metabolism of tryptophan, an important neurotransmitter. Long COVID GI symptoms resemble a Disorder of Gut Brain Interaction (DGBI) such as post infection Irritable Bowel Syndrome (IBS). Current standards of treatment for IBS can guide our treatment of Long COVID patients. Dysautonomia, a frequent Long COVID condition affecting the autonomic nervous system, can also affect the GI tract, and must be considered in Long COVID patients with GI symptoms. Long COVID symptoms fall within the broader category of Infection Associated Chronic Conditions (IACCs). Research into the GI symptoms of Long COVID may further our understanding of other post infection chronic GI conditions, and elucidate the roles of therapeutic options including antivirals, probiotics, neuromodulators, and treatments of dysautonomia., Competing Interests: Declaration of competing interest No competing interests., (Copyright © 2024 Elsevier Inc.

Objective: To analyze in-hospital and 1-year morbidity and mortality associated with acute gastrointestinal dysfunction in critically ill patients with COVID-19 via a prespecified scoring system., Methods: Between March and July 2020, consecutive hospitalized patients with COVID-19 from a single institution were retrospectively analyzed by medical chart review. Only those who remained in the intensive care unit for more than 24 hours were included. Gastrointestinal dysfunction was assessed according to a predefined 5-point progressive gastrointestinal injury scoring system, considering the first 7 days of hospitalization. Laboratory data, comorbidities, the need for mechanical ventilation, the duration of intensive care unit stay, and subsequent in-hospital and 1-year mortality rates were also recorded., Results: Among 230 patients who were screened, 215 were included in the analysis. The median age was 68 years (54 - 82), and 57.7% were male. The total gastrointestinal dysfunction scores were 0 (79.1%), I (15.3%), II (4.7%), III (0.9%), and IV (0%). Any manifestation of gastrointestinal dysfunction was present in 20.9% of all patients and was associated with longer lengths of stay (20 days [11 - 33] versus 7 days [4 - 16]; p < 0.001] and higher C-reactive protein levels on admission (12.8mg/mL [6.4 - 18.4] versus 5.7mg/mL [3.2 - 13.4]; p < 0.001). The gastrointestinal dysfunction score was significantly associated with mortality (OR 2.8; 95%CI 1.7 - 4.8; p < 0.001) and the need for mechanical ventilation (OR 2.8; 95%CI 1.7 - 4.6; p < 0.001). Both in-hospital and 1-year death rates progressively increased as gastrointestinal dysfunction scores increased., Conclusion: In the current series of intensive care unit patients with COVID-19, gastrointestinal dysfunction severity, as defined by a prespecified scoring system, was predictive of adverse in-hospital and 1-year outcomes.

Rationale: The postoperative gastrointestinal dysfunction after cesarean section is commonly presented as uncomfortable symptoms such as abdominal pain and distension. As a novel traditional Chinese medicine characteristic therapy, the fire dragon cupping can effectively enhance intestinal peristalsis and improve the gastrointestinal discomforts by using the manipulation and moxibustion heat to stimulate acupuncture points. The purpose of this report is to provide a new approach and new ideas for rapid rehabilitation of gastrointestinal dysfunction after cesarean section., Patient Concerns: A parturient woman, 39 years old, pregnancy 4, delivery 2, underwent lower uterine segment cesarean section under intrathecal anesthesia due to scarred uterus. On the 3rd day after cesarean section, the anus still did not exhaust and defecate, so this parturient woman complained of obvious abdominal pain, abdominal distension, nausea, and vomiting., Diagnoses: The measured abdominal circumference was 96 cm, and the bowel sounds weakened on auscultation; the plain abdominal radiograph indicated a small amount of pneumomediastinum, thus the incomplete intestinal obstruction was considered., Interventions: The parturient woman was treated with fire dragon cupping treatment in her back and abdomen once a day, each time about 30 to 40 minutes, 3 consecutive days of treatment., Outcomes: On the 4th day after cesarean section, the parturient woman naturally had anal exhaust and defecated watery stools twice, without complaint of abdominal pain distension., Lessons: Under the guidance of the concept of rapid rehabilitation nursing in obstetrics, according to the principle of making gradual and orderly progress, risk management of gastrointestinal dysfunction after cesarean section is carried out in the early stage, the fire dragon cupping and individualized rehabilitation scheme are implemented, and the parturient women with gastrointestinal dysfunction after cesarean section are actively treated., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Rationale: This article presents a complex case of refractory Henoch-Schönlein purpura (HSP), initially manifesting with complex gastrointestinal (GI) symptoms, and discusses diagnostic and therapeutic challenges encountered. It aims to enhance understanding of the disease and provide evidence for the potential efficacy of intravenous immunoglobulin (IVIG) treatment in this condition., Patient Concerns: A 16-year-old male patient presented with persistent abdominal pain, nausea, vomiting, and constipation for 8 days, leading to hospital admission., Diagnoses: Establishing a definitive diagnosis was challenging initially due to the absence of typical petechiae. However, the appearance of characteristic petechiae subsequently confirmed the diagnosis of HSP., Interventions: Initial treatment with methylprednisolone sodium succinate for 3 days failed to elicit improvement. Subsequently, IVIG was introduced as a combination therapy., Outcomes: Following the combined administration of IVIG, the patient experienced complete resolution of abdominal pain, petechiae, and arthralgia within 4 days., Lessons: This case highlights the importance of considering HSP in the differential diagnosis of patients with complex GI symptoms. Furthermore, it suggests that IVIG may be a valuable therapeutic option for HSP patients with refractory GI symptoms. High-quality comparative trials are needed to establish more definitive evidence for the effectiveness of IVIG and to develop specific treatment guidelines., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

The occurrence of gastrointestinal dysfunction is widely recognized as a prevalent complication in patients with sepsis. To investigate clinical effect of Sini Decoction at acupoint on gastrointestinal dysfunction in sepsis patients. Seventy-five patients with gastrointestinal dysfunction caused by sepsis were randomly divided into 2 groups. Treatment group received routine Western medicine treatment combined with Sini Decoction at acupoint, while control group treated with talcum powder at acupoint. Treatments in both groups lasted 7 days. Changes in the acute physiology and chronic health evaluation II score, sequential organ failure assessment score, mechanical ventilation duration, the length of Intensive Care Unit (ICU) stay, enteral nutrition tolerance scores, abdominal circumference, gastric residual volume, bowel sounds, and serum index were observed. After treatment, the enteral nutrition tolerance score, abdominal circumference, gastric residual volume, and levels of lactate and interleukin-6 were significantly lower in the treatment group compared to the control group. Bowel sounds were more active and motilin levels were higher in the treatment group. Additionally, the length of ICU stay was significantly shorter in the treatment group than in the control group. Our findings demonstrated that the application of Sini Decoction at acupoints in sepsis patients with gastrointestinal dysfunction can effectively enhance gastrointestinal function, leading to a reduction in ICU stay duration and an improvement in patients' prognosis., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Aim: To assess the occurrence and risk factors of gastrointestinal (GI) dysfunction during enteral nutrition (EN) in critically ill patients supported with mechanical ventilation., Design: Prospective observational study., Methods: Totally 252 patients admitted at a mixed medical-surgical ICU were enrolled. GI symptoms and the potential risk variables were recorded during the first 14 days of EN., Results: The incidence of GI dysfunction was 65.5%, and the incidence of diarrhoea, constipation, abdominal distension, and upper GI intolerance was 28.2%, 18.3%, 6.7% and 12.3%, respectively. The median onset days of constipation, diarrhoea, abdominal distension and UDI was 3, 5, 5 and 6 days, respectively. Multivariable Cox regression analysis showed a significant relationship between GI dysfunction and age (HR = 2.321, 95% CI: 1.024-5.264, p = 0.004), APACHE-II score at ICU admission (HR = 7.523, 95% CI: 4.734-12.592, p = 0.018), serum albumin level (HR = 0.594, 95% CI: 0.218-0.889, p = 0.041), multidrug-resistant bacteria-positive culture (HR = 6.924, 95% CI: 4.612-10.276, p<0.001), negative fluid balance (HR = 0.725, 95% CI: 0.473-0.926, p = 0.037), use of vasopressor drugs (HR = 1.642, 95% CI: 1.297-3.178, p<0.001), EN way (HR = 6.312, 95% CI: 5.143-11.836, p<0.001), infusion rate (HR = 1.947, 95% CI: 1.135-3.339, p<0.001), and intra-abdominal hypertension (HR = 3.864, 95% CI: 2.360-5.839, p<0.001)., Conclusion: Critically ill patients supported with mechanical ventilation are at a high risk of GI dysfunction. Interventions such as the use of laxatives or prokinetic agents, control of EN infusion rate, and maintaining a normal state of hydration, might be beneficial for the prevention of GI dysfunction in critically ill patients., Patient or Public Contribution: No., (© 2024 The Author(s).

Langerhans cell histiocytosis (LCH) is a heterogeneous histiocytosis characterized by proliferation of Langerhans cells. While less common, manifestations of digestive tract involvement in LCH remain largely unrevealed. We conducted a retrospective analysis of demographics, clinical, endoscopic, genetic and follow-up data from 13 adult patients with pathologically confirmed gastrointestinal involvement of LCH (LCH-GI), in a single-center cohort of 465 patients. Digestive tract involvement was observed in 2.80% of LCH patients. At LCH-GI diagnosis, 7 patients (53.8%) had unifocal lesions, and 6 patients (46.2%) had multisystem disease. 6 patients (46.2%) experienced no gastrointestinal symptoms at LCH-GI onset, while others were symptomatic. Stomach was most commonly affected (61.5%), followed by esophagus (23.1%), colon (7.7%) and anus (7.7%). Endoscopic findings varied among 12 patients, including submucosal bulge (8 patients, 66.7%) and non-bulging lesions (4 patients, 33.3%) such as erosions, coarse granular mucosa, and regional abnormal coloration. Among 8 patients with genetic analysis, BRAF V600E mutation was detected in 5 patients (62.5%). The estimated 1-year overall survival rate was 91.7%. Progression-free survival of patients with submucosal bulges under endoscopy was significantly better than those with non-bulging lesions. This study presents 13 cases of LCH with digestive tract involvement. We emphasize the importance of endoscopy and biopsy for pathological examination of lesions such as submucosal bulges and erosions under endoscopy to assist in early detection of LCH. Comprehensive systemic assessment and regular endoscopic monitoring are essential in patient management. Treatment should be individualized with dynamic adjustments during follow-up., (© 2024.

Minnesota acute graft versus host disease (AGVHD) risk score is a validated tool to stratify newly-diagnosed patients into standard-risk (SR) and high-risk (HR) groups with ~85% having SR AGVHD. We aimed to identify factors for further risk-stratification within Minnesota SR patients. A single-center, retrospective analysis of consecutive patients between 1/2010 and 12/2014 was performed. Patients who developed AGVHD within 100 days and treated with systemic corticosteroids were included (N = 416), 356 (86%) of which were Minnesota SR and 60 (14%) had HR AGVHD. Isolated upper gastrointestinal (GI) AGVHD patients had significantly better day 28 and 56 CR/PR rates (90% vs. 72%, p = 0.004) and (83% vs 66%, p = 0.01), respectively, and lower 1-year non-relapse mortality (NRM; 10% vs. 22%; HR 0.4, p = 0.03). Lower GI AGVHD had less favorable outcomes with 1-year NRM of 40% (HR 2.1, p = 0.001), although CR/PR rates were not statistically different. In multivariate analysis, lower GI involvement (HR 2.6, p < 0.001), age ≥ 50 (HR 2.9, p < 0.001) and HCT-CI > 3 (HR 2.1, p = 0.002) predicted for 1-year NRM. Heterogeneity within Minnesota SR patients requires consideration in clinical trials, as distinct outcomes are observed in those with isolated upper GI and lower GI AGVHD, highlighting the importance of stratification in clinical trial design., (© 2024.

Aim: Postoperative gastrointestinal dysfunction (POGD) is a common complication following colorectal surgery. This study aimed to investigate the incidence and risk factors of POGD after minimally invasive surgery and to assess the relationship between robotic surgery, POGD, and their outcomes., Method: Patients who had undergone minimally invasive colorectal surgery at our institution between July 2018 and November 2023 were retrospectively enrolled. POGD was diagnosed based on the presence of two or more intestinal symptoms within 72 h or more after surgery. Risk factors were identified through regression analyses, and the impact of POGD on outcomes was assessed using linear regression.The association between those factors was assessed using subgroup analysis and hierarchical regression., Results: A total of 226 patients were included in the analysis, including 33 with POGD. POGD occurred in 14.6% of patients, with a lower incidence in robotic surgery (7.3%) than in laparoscopic surgery (19.8%). Multivariate analysis indicated that robotic surgery had a protective effect, while blood loss exceeding 50 ml was an independent risk factor for POGD. POGD was also correlated with longer length of stays and higher costs. The association between POGD, length of stay, and cost varied depending on the surgical platform. Robotic surgery exacerbated the effect of POGD on short-term outcomes, which aligned with the observed significant interaction effect., Conclusion: POGD remains a prevalent postoperative disease. Preventive strategies, including meticulous hemostasis techniques and robotic surgery, should be prioritized by healthcare professionals to reduce POGD risk, improve short-term outcomes, and preserve healthcare resources., (© 2024.

Objectives: Specific human leukocyte antigen (HLA) haplotypes are associated with Behçet's disease. Because the effects of HLA-A26 and its combination with HLA-B51 on organ involvement in Behçet's disease have not been well demonstrated, we aimed to examine them., Methods: This multicentre, cross-sectional, observational study enrolled patients with Behçet's disease who visited Kyoto University Hospital between 2018 and 2021 or Kurashiki Central Hospital between 2006 and 2016 (n = 200). Disease severity was evaluated using the Krause score., Results: Uveitis and gastrointestinal involvement were observed in 95/196 and 57/167 patients, respectively. The HLA alleles identified were HLA-B51 (n = 52/106), HLA-A26 (n = 25/88), and HLA-B51 and HLA-A26 (n = 6/88). In patients harbouring HLA-B51, the presence of HLA-A26 was associated with higher frequencies of uveitis (P = .03) and coexistence of uveitis and gastrointestinal involvement (P = .002) and higher Krause scores (P = .02). Furthermore, the presence of HLA-A26 was associated with a higher frequency of uveitis in patients with gastrointestinal involvement (P = .001) and gastrointestinal involvement in patients with uveitis (P = .001)., Conclusions: Since specific HLA haplotypes and their combinations are associated with organ involvement, both HLA-A and HLA-B haplotypes should be confirmed when screening for affected organs., (© Japan College of Rheumatology 2024.

Background: Idiopathic Parkinson's disease (IPD) is associated with a spectrum of nonmotor symptoms (NMS) that contribute as much to the burden of the disease as the more obvious motor abnormalities. There is a paucity of literature determining the association between NMS and the severity of IPD, especially in rural eastern parts of India., Aims of Study: This study explores the frequency of NMS in patients with IPD and determines the association between NMS and the severity of IPD., Materials and Methods: A cross-sectional observational study involving 65 serially enrolled IPD patients (diagnosed as per United Kingdom Parkinson's Disease Society Brain Bank Clinical Diagnostic Criteria) was conducted over a period of 18 months. The patients were evaluated for disease severity as per the Hoehn and Yahr scale (original) and were subsequently evaluated with a predesigned and validated Parkinson's Disease Non-Motor Symptoms Questionnaire. Pearson's Chi-squared test for independence of attributes or Fisher's exact test was used for comparison of categorical variables across the groups. Continuous variables were compared using a one-way analysis of variance (ANOVA) test., Results: The most common presenting NMS of IPD was low mood ( n = 61; 93.85%), followed by apathy ( n = 59; 90.77%), impaired concentration ( n = 58; 89.23%), restless leg ( n = 54; 83.08%), and tenesmus ( n = 54; 83.08%). A majority of the neuropsychiatric symptoms, autonomic dysfunctions, sleep abnormalities, gastrointestinal manifestations, and sensory abnormalities individually showed a statistically significant relation with the severity of IPD., Conclusion: Common presenting NMS include neuropsychiatric manifestations, autonomic symptoms, sleep-related symptoms, and gastrointestinal manifestations. Most of the NMS are significantly related to disease severity., (© Journal of the Association of Physicians of India 2024.)

Objective: To explore the clinical and genetic characteristics of patients with Ehlers-Danlos syndrome (EDS) and gastrointestinal involvement. Methods: We retrospectively collected the clinical data of patients with EDS and gastrointestinal involvement from the electronic medical records at Peking Union Medical College Hospital (PUMCH) from January 2003 to September 2023. Additionally, we conducted a systematic review by searching cases with EDS and gastrointestinal involvement in PubMed, Embase, Web of Science, and the Cochrane Library databases from January 2000 to September 2023. Results: Ninety-four patients with EDS and gastrointestinal involvement were retrieved, including five patients from PUMCH and 89 patients from 80 published articles. The average age of patients was (29±14) years. The most common manifestation of gastrointestinal involvement was gastrointestinal perforation ( n =46, 48.9%), followed by functional gastrointestinal symptoms ( n =33, 35.1%), and digestive arterial disorders ( n =10, 10.6%). The most common clinical subtype was vascular-EDS (vEDS) ( n= 50, 53.2%) followed by hypermobile-EDS (hEDS) ( n =20, 21.3%). The most frequent genetic mutation occurred in the COL3A1 gene ( n= 30, 31.9%). Among patients with vEDS, gastrointestinal manifestations included gastrointestinal perforation ( n= 33, 66.0%), arterial lesions ( n= 9, 18.0%), and functional gastrointestinal symptoms ( n= 7, 14.0%). Among patients with hEDS, gastrointestinal manifestations included functional gastrointestinal symptoms ( n =18, 90.0%), visceral prolapse ( n =3, 15.0%) and intestinal volvulus ( n =1, 5.0%). Conclusions: The most common subtypes of gastrointestinal involvement in EDS were vEDS and hEDS. Patients with hEDS mainly presented with functional gastrointestinal symptoms, whereas those with vEDS primarily showed gastrointestinal perforation and digestive arterial disorders.

Objectives: This retrospective study aimed to investigate the clinical characteristics and genetic findings in paediatric patients with gastrointestinal involvement in Behçet's disease (BD), elucidating the spectrum of autoinflammatory syndromes mimicking BD in this young population., Methods: Fifty paediatric patients diagnosed with BD between January 2016 and December 2022, including 24 (48%) with gastrointestinal involvement, underwent comprehensive analysis. Clinical presentations, laboratory examinations, gastrointestinal endoscopy, and genetic tests were conducted, with patients stratified based on genetic results for rigorous comparative clinical analysis., Results: The cohort, with a median age of disease onset at 4.0 years, predominantly manifested with recurrent oral ulcers (100%). Gastrointestinal symptoms were prevalent in 83.3%, with abdominal pain (70%) and haematochezia (16.7%) being notable. Endoscopic evaluations unveiled lesions primarily in the terminal ileum and ileocecal region, with diverse ulcers across various anatomical sites. While 70.8% initially met ICBD criteria, only 41.6% fulfilled new paediatric classification criteria. Genetic analysis in 18 patients unveiled pathogenic variants in 7, with the genetic-positive group exhibiting earlier onset and more atypical symptoms. Noteworthy cases included X-linked deficiency in ELF4, A20 haploinsufficiency, and Majeed syndrome, with two cases revealing chromosomal abnormalities such as trisomy 8 syndrome. Comparative analysis underscored earlier disease onset, heightened inflammatory markers, and distinctive gastrointestinal lesions in the genetic-positive cohort., Conclusions: Identification of monogenic diseases and chromosomal abnormalities resembling BD underscores the imperative of precise diagnosis for tailored treatment and genetic counselling. Expanding genetic screening initiatives holds promise for enhancing our comprehension of the genetic landscape associated with BD.

Objective: Systemic lupus erythematosus (SLE) constitutes an autoimmune disorder with potential involvement of the gastrointestinal system (GIS). Our objective was to assess the gastrointestinal (GI) manifestations in patients diagnosed with childhood onset SLE., Methods: The study cohort consisted of 123 patients with childhood onset-SLE and GIS involvement from 16 referral departments of pediatric rheumatology. All participants met the Systemic Lupus International Collaborating Clinics criteria., Results: Out of 123 patients, 78 (63.4%) exhibited GIS involvement at the initial SLE diagnosis, whereas the remaining 45 (36.6%) developed GI symptoms after a median duration of 12 (3-140) months. Eighty-two (66.7%) individuals experienced symptoms related to the GI tract, whereas the remaining patients received a diagnosis of GI involvement through laboratory assessments. The predominant initial GIS involvement symptom was abdominal pain, observed in 77 (62.6%) patients, followed by elevated hepatic transaminases in 70 (56.9%), hepatomegaly in 40 (32.5%), diarrhea in 26 (21.1%), and jaundice in 11 (8.9%) patients. The GIS involvement was associated with SLE in 82 (78.6%), while it resulted from drug-related adverse events in 35 (28.5%) patients or comorbidities in 6 (0.5%) patients., Conclusion: GIS involvement should be considered in all childhood onset-SLE patients, especially in the presence of suggestive symptoms or elevated hepatic transaminases. It is also crucial to consider SLE in the differential diagnosis of GIS manifestations in children. Apart from GIS involvement directly associated with SLE, adverse events of drugs should be kept in mind., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

This study aimed to identify severe gastrointestinal ailments in patients with systemic sclerosis (SSc), investigate the role of antibodies in gastrointestinal disorders, and explore the relationship between limited cutaneous SSc (lcSSc) and diffuse cutaneous SSc (dcSSc) in terms of gastrointestinal involvement and its association with skin stiffness. We used the University of California, Los Angeles, Scleroderma Clinical Trials Consortium Gastrointestinal Tract Instrument 2.0 (UCLA SCTC GIT 2.0) questionnaire to assess gastrointestinal disturbances in 100 patients with SSc. Gastrointestinal impairment was categorized into three levels: absence of or minor symptoms, moderate symptoms, and severe symptoms, as indicated by the total gastrointestinal tract (GIT) score. Comparing 27 patients with dcSSc and 73 patients with lcSSc, severe gastrointestinal disturbances were found in 7.4% of patients with dcSSc and 4.1% of patients with lcSSc. A total of 18.0% of anticentromere antibody (ACA)-positive patients exhibited moderate to severe symptoms, while 9.1% of antitopoisomerase 1 antibody-positive patients displayed similar symptoms. The average disease duration in patients with severe symptoms was 15.0 years, in those with moderate symptoms was 10.3 years, and in those who were symptom-free or mildly affected was 8.5 years. Among 16 patients with moderate to severe gastrointestinal disorders, a positive correlation was observed between the modified Rodnan skin thickness score (mRSS) and total GIT score. In addition, a positive correlation was identified between fecal incontinence and mRSS, with weaker correlations for reflux and bloating symptoms. Patients with gastrointestinal disorders showed a tendency to worsen over time, particularly in ACA-positive patients with dcSSc. Furthermore, a correlation was observed between mRSS and fecal incontinence, reflux, and abdominal bloating in patients with moderate to severe gastrointestinal disturbances., (© 2024 Japanese Dermatological Association.)

Gastrointestinal (GI) sequelae, such as vomiting, hyperacidity, dysphagia, dysmotility, and diarrhea, are nearly universal among patients with nephropathic cystinosis. These complications result from disease processes (e.g., kidney disease, cystine crystal accumulation in the GI tract) and side effects of treatments (e.g., cysteamine, immunosuppressive therapy). GI involvement can negatively impact patient well-being and jeopardize disease outcomes by compromising drug absorption and patient adherence to the strict treatment regimen required to manage cystinosis. Given improved life expectancy due to advances in kidney transplantation and the transformative impact of cystine-depleting therapy, nephrologists are increasingly focused on addressing extra-renal complications and quality of life in patients with cystinosis. However, there is a lack of clinical data and guidance to inform GI-related monitoring, interventions, and referrals by nephrologists. Various publications have examined the prevalence and pathophysiology of selected GI complications in cystinosis, but none have summarized the full picture or provided guidance based on the literature and expert experience. We aim to comprehensively review GI sequelae associated with cystinosis and its treatments and to discuss approaches for monitoring and managing these complications, including the involvement of gastroenterology and other disciplines., (© 2024.

Although not often discussed, many of the neuromuscular disorders (NMDs) affect the gastrointestinal tract (GIT). Depending on the type of NMD, the prevalence of GIT involvement ranges from <5% (e.g. hereditary neuropathies, myofibrillar myopathies) to 100% (e.g. MNGIE, OPMD). Particularly in NMDs with multisystem affection, involvement of the GIT can dominate the clinical presentation or at least make up a significant part of the clinical picture. The most prominent representatives of NMDs with multisystem involvement are the mitochondrial disorders (MIDs) and the myotonic dystrophies. The best known syndromic MIDs with GIT involvement are MNGIE, MELAS, Leigh, and Pearson syndromes. Among neuropathies, GIT involvement is most commonly found in ALS and GBS. GIT involvement may also be a feature of myasthenia. The clinical manifestations of GIT involvement are diverse and can affect the entire GIT, from the teeth to the rectum, including the liver and pancreas. The most well-known clinical manifestations of GIT involvement are dysphagia, nausea, vomiting, reflux, hollow organ dysmotility, hepatopathy, diabetes, diarrhea, constipation, and fecal incontinence. Even if treatment can usually only be symptomatic, the therapeutic options are diverse, are often effective, and can significantly and beneficially influence the course of the underlying NMD., (© 2024 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Introduction: Colorectal cancer (CRC) is prevalent in the developed world, with unhealthy lifestyles and diet contributing to rising incidence. Advances in effective screening, diagnosis, and treatments have led to improved survival rates, but CRC survivors suffer poorer long-term gastrointestinal consequences than the general population. However, the current state of clinical practice around provision of health services and treatment options remains unclear., Purpose: We aimed to identify what supportive care interventions are available to manage gastrointestinal (GI) symptoms for CRC survivors., Methods: We searched Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycINFO, and CINAHL from 2000 to April 2022 for resources, services, programs, or interventions to address GI symptoms and functional outcomes in CRC. We extracted information about characteristics of supportive care interventions, the study design, and sample characteristics from included studies, and performed a narrative synthesis RESULTS: Of 3807 papers retrieved, seven met the eligibility criteria. Types of interventions for managing or improving GI symptoms included two rehabilitation, one exercise, one educational, one dietary, and one pharmacological. Pelvic floor muscle exercise may help to resolve GI symptoms more quickly in the post-operative recovery phase. Survivors may also benefit from rehabilitation programs through improved self-management strategies, especially administered soon after completing primary treatment., Conclusions/implications for Cancer Survivors: Despite a high prevalence and burden of GI symptoms post-treatment, there is limited evidence for supportive care interventions to help manage or alleviate these symptoms. More, large-scale randomized controlled trials are needed to identify effective interventions for managing GI symptoms that occur post-treatment., (© 2023. The Author(s).)

Background and Study Aims: Chronic kidney disease (CKD) is a well-known risk factor of gastrointestinal angiectasia (GIA). The aim was to compare this population with CDK patients without GIA., Methods: Patients followed in the Nephrology Department of Tenon Hospital for which an endoscopy was performed between 2012 and 2022 were identified. Those with at least one GIA lesion were included ("GIA+" group). A matched control group for age, sex and GFR stage of patients with CKD and no GIA lesion ("GIA-" group) was constituted. A subgroup analysis compared patients with (SB+) and without (SB-) small-bowel involvement., Results: A total of 55 patients were included in the GIA+ group. 36.3 % (n = 20) were active smokers and 29.1 % (n = 16) had peripheral arterial disease versus 16.4 % (n = 9) (OR 2.89, p = 0.03), and 9.1 % (n = 5) (OR 4.05, p = 0.015) in the GIA- group. Thirteen patients (23.6 %) had a SB lesion. Duodenal involvement was present in 69.2 % of cases in the SB+ group versus 28.6 % in the SB- group (p = 0.02). Median number of endoscopies, hemostatic technics and hospitalizations was 7, 3 and 6, versus 2 (p = 0.0001), 1 (p = 0.001) and 1 (p = 0.0002) in the SB- group., Conclusions: CKD patients with GIA had a greater cardiovascular risk with a higher incidence of vascular nephropathy. Small-bowel GIA were associated with a higher morbidity., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships, which may be considered as potential competing interests: Pr Xavier Dray discloses the following COI: Alfasigma, Bouchara Recordati, Fujifilm, Medtronic, Norgine, Sandoz, Augmented Endoscopy, Provepharma, Abbvie.

Objective: To evaluate medium-term self-reported respiratory and gastrointestinal (GI) outcomes in children with congenital diaphragmatic hernia (CDH)., Design: Self-reported respiratory and GI outcomes correlated with prenatal severity indicators., Setting: Prospective study at three fetal medicine units., Population: Families of children prenatally diagnosed with isolated, left-sided CDH surviving for >1 year., Methods: Families received validated questionnaires for GI outcomes (Infant Gastroesophageal Reflux Questionnaire Revised, I-GERQ-R, for infants aged <2 years, or Paediatric Gastro-oesophageal Symptom and Quality of Life Questionnaire, PGSQ, for children aged aged 2-8 years or >9 years) and respiratory outcomes (preschool respiratory outcome questionnaire, for children aged ≤5 years, or the International Study of Asthma and Allergies in Childhood asthma questionnaire, for children aged 6-8 years or ≥9 years). Prenatal data collected from the medical records included lung size (percentage observed/expected lung-to-head ratio, O/E LHR %), liver position, fetal endoluminal tracheal occlusion (FETO) gestational age (GA) at delivery, and perinatal data included birthweight, location, patch repair and respiratory support., Main Outcome Measures: The GI and respiratory scores were correlated with O/E LHR using linear and logistic regression models. Univariate analysis was used to evaluate associations with perinatal variables., Results: We obtained 142 responses from 342 families (representing a response rate of 45%). The baseline characteristics of participants and non-participants were comparable. No correlations between perinatal variables and respiratory or GI scores were identified. Children aged ≤5 years with lower O/E LHR values reported higher respiratory scores (P = 0.0175); this finding was not reported in older children. Overall, the children who underwent FETO (n = 51) had GI (P = 0.290) and respiratory (P = 0.052) scores that were comparable with those of children who were expectantly managed., Conclusions: Families and children with prenatally diagnosed CDH reported fewer respiratory symptoms with increasing age. There was no correlation between O/E LHR or the use of FETO and self-reported outcomes., (© 2024 John Wiley & Sons Ltd.)

Diabetes mellitus (DM) has a systemic consequence, influencing many systems of the body, including metabolic functions. This study aimed to determine the prevalence of gastrointestinal complications among patients with type 2 DM in the Asser region of Saudi Arabia, identify sources of information, and investigate the association of these symptoms with disease duration and glycated hemoglobin. This cross-sectional study was conducted between November 13 and December 27, 2023. The questionnaire collected demographic data including age, sex, education, employment, income, and nationality, and 16 questions (5 points for each symptom) about the frequency of gastrointestinal symptoms in the past 3 months. The total score was 80, participants were categorized based on their total scores into 2 groups: those scoring 40 or below, and those scoring above 40. A total of 230 patients were included in this study, their median age was 32.0 (24.00) years, 60% were men, 63.9% were married, 38.7% earned between 5000 and 10,000 Saudi Riyal/month, 85.2% did not work in the medical field, 39.1% held university degrees, 54.8% did not have health insurance, 70.4% did not smoke, 35.7% worked in government jobs, 63% lived in urban areas, 95.2% were Saudi and 53.5% had only DM. More than half of the respondents, 57.4%, relied on doctors for information about DM. Dysmotility symptoms were common: dyspepsia affected 26.5% often and 5.7% always; early satiety impacted 24.3% often and 5.2% always; and bloating affected 28.3% often and 10.9% always. Constipation/diarrhea were a common complaint, with 23.5% of patients experiencing them often and an additional 4.8% reporting it always. Stool consistency also varied widely, with 21.7% experiencing lumpy or hardened stool. Health insurance status and having chronic diseases showed significant association with the severity of symptoms. Duration of diabetes and glycated hemoglobin were associated with the frequency of the symptoms. Gastrointestinal symptoms are common among diabetic patients in Aseer. The frequency of symptoms is associated with glycemic control, duration of diabetes, and health insurance status. These findings highlight the need for improved management and support for better gastrointestinal health in diabetes., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Gastrointestinal (GI) complications are significant manifestations of COVID-19 and are increasingly being recognized. These complications range from severe acute pancreatitis to colitis, adding complexity to diagnosis and management. A comprehensive database search was conducted using several databases. Our inclusion criteria encompassed studies reporting severe and long-term GI complications of COVID-19. Digestive disorders were categorized into infections, inflammatory conditions, vascular disorders, structural abnormalities, other diagnoses, and undiagnosed conditions. Of the 73 studies that were selected for full-text review, only 24 met our inclusion criteria. The study highlights a broad range of gastrointestinal complications following COVID-19 infection (excluding liver complications, which are examined separately), including inflammatory conditions, such as ulcerative colitis (UC), acute pancreatitis, and multisystem inflammatory syndrome in children (MIS-C). Other GI complications were reported such as vascular disorders, including diverse thrombotic events and structural abnormalities, which ranged from bowel perforations to adhesions. Additionally, undiagnosed conditions like nausea and abdominal pain were prevalent across different studies involving 561 patients. The findings emphasize the substantial impact of COVID-19 on the GI tract. Ongoing research and monitoring are crucial to understanding the long-term effects and developing effective management strategies for these complications.

Gastrointestinal (GI) tract involvement affects up to 90% of Systemic sclerosis (SSc) patients. The presence of GI symptoms is assessed by the University of California, Los Angeles, and Scleroderma Clinical Trials Consortium Gastrointestinal Scale (UCLA SCTC GIT 2.0). Microbial translocation (MT) is reported in SSc patients consequently to increased intestinal permeability due to intestinal damage (ID) and dysbiosis. Aim of this study was to assess circulating levels of LBP and EndoCab IgM (markers of MT), IL-6 (marker of inflammation), I-FABP and Zonulin (markers of ID) in a cohort of SSc patients and healthy controls (HC). Moreover, we aimed to correlate these parameters with severity of GI symptoms. UCLA SCTC GIT 2.0 questionnaire was administered to 60 consecutive SSc patients. Markers of MT, inflammation and ID were evaluated in SSc patients and HC. SSc patients had higher median value of markers of MT, inflammation and ID than HC. The logistic regression analysis showed LBP as the only variable associated with an UCLA total score "moderate-to-very severe" [OR 1.001 (CI 95%: 1.001-1.002), p < 0.001]. The logistic regression analysis showed LBP [OR 1.002 (CI 95%: 1.001-1.003), p < 0.01] and disease duration [OR 1.242 (CI 95%: 1.023-1.506), p < 0.05] as variables associated with UCLA distension/bloating "moderate-to-very severe". The logistic regression analysis showed LBP as the only variable associated with UCLA diarrhea "moderate-to-very severe" [OR 1.002 (CI 95%: 1.001-1.003), p < 0.01]. SSc patients with dysregulation gut mucosal integrity expressed by high levels of MT and ID biomarkers had more severe GI symptoms., (© 2024. The Author(s).)

Pelvic irradiation, a crucial treatment for pelvic malignancies, is associated with the risk of gastrointestinal (GI) damage due to the high proliferation rate of epithelial cells. The radiosensitive gastrointestinal tract acts as a dose-limiting organ. High doses of ionizing radiation can cause inflammation and rupture of mucosal barriers and can also lead to intestinal fibrosis. Intestinal damage can cause acute to chronic complications, reducing patients' quality of life. The gut microbiota plays a vital role in maintaining gut health, and any changes in the gut microbial composition can worsen damage, emphasizing the importance of therapies that target and sustain the gut microbiota during radiotherapy. One potential strategy to prevent radiation-induced GI damage is to use bacterial supplements. Research suggests that probiotic supplementation may alleviate radiation-induced gastrointestinal damage, maintaining intestinal morphology and decreasing epithelial injury in cancer patients. The observed protective effects occur through various mechanisms, including antioxidant activities, modulation of the immune response, and preservation of gut barrier function. To optimize probiotic therapies, it is imperative to elucidate these mechanisms. The efficiency of probiotics as radioprotectors is highly dependent on the time and dose of administration, and their interaction with the host immune system is a key facet of their therapeutic potential. This review explores the potential benefits of bacterial supplementation in mitigating radiation-induced GI damage and the underlying mechanism. This highlights the need for further research to establish standardized protocols and refine probiotic supplementation strategies, underscoring the potential for enhancing therapeutic outcomes in patients undergoing pelvic radiotherapy., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 The Authors.

Aim: To highlight the relevance of gastrointestinal manifestations of cytomegalovirus infection (CMVI), to highlight the main risk factors for the development of this pathology, current trends in diagnosis and treatment., Key Points: CMVI is one of the most common opportunistic diseases, characterized by a variety of manifestations from asymptomatic to severe generalized forms affecting internal organs and body systems. The prevalence of CMVI worldwide ranges from 20 to 95%. Particular attention is paid to timely diagnosis, treatment and prevention of CMVI. The "gold standard" in the diagnosis of digestive diseases associated with CMVI is immunohistochemical examination and detection of cytomegalovirus (CMV) DNA in tissues using the polymerase chain reaction (PCR). Of undoubted interest in the diagnosis of CMV is the detection of CMV DNA in stool using digital PCR. Compared to quantitative PCR, digital PCR has higher accuracy and sensitivity. As first-line therapy, the drugs of choice are ganciclovir and valganciclovir. Maribavir has been successfully used to treat patients with CMV infection refractory to one or more previous therapies. One of the promising directions in the treatment of cytomegalovirus colitis in patients with ulcerative colitis is fecal microbiota transplantation., Conclusion: Timely identification of risk factors for the development of CMV infection, the introduction of innovative methods and approaches in diagnosis, and the use of effective methods for treating diseases of the digestive system associated with CMV infection can improve the prognosis of the underlying disease and reduce the risk of developing urgent conditions in gastroenterology.

Background: Radiotherapy (RT) is effective for cervical cancer but causes late side effects (SE) to nearby organs. These late SE occur more than 3 months after RT and are rated by clinical findings to determine their severity. While imaging studies describe late gastrointestinal (GI) SE, none demonstrate the correlation between the findings and the toxicity grading. In this study, we demonstrated the late GI toxicity prevalence, CT findings, and their correlation., Methods: We retrospectively studied uterine cervical cancer patients treated with RT between 2015 and 2018. Patient characteristics and treatment(s) were obtained from the hospital's databases. Late RTOG/EORTC GI SE and CT images were obtained during the follow-up. Post-RT GI changes were reviewed from CT images using pre-defined criteria. Risk ratios (RR) were calculated for CT findings, and multivariable log binomial regression determined adjusted RRs., Results: This study included 153 patients, with a median age of 57 years (IQR 49-65). The prevalence of ≥ grade 2 RTOG/EORTC late GI SE was 33 (27.5%). CT findings showed 91 patients (59.48%) with enhanced bowel wall (BW) thickening, 3 (1.96%) with bowel obstruction, 7 (4.58%) with bowel perforation, 6 (3.92%) with fistula, 0 (0%) with bowel ischemia, and 0 (0%) with GI bleeding. Adjusted RRs showed that enhanced BW thickening (RR 9.77, 95% CI 2.64-36.07, p = 0.001), bowel obstruction (RR 5.05, 95% CI 2.30-11.09, p < 0.001), and bowel perforation (RR 3.82, 95% CI 1.96-7.44, p < 0.001) associated with higher late GI toxicity grades., Conclusions: Our study shows CT findings correlate with grade 2-4 late GI toxicity. Future research should validate and refine these findings with different imaging and toxicity grading systems to assess their potential predictive value., (© 2024. The Author(s).)

Acute gastrointestinal injury (AGI) is common in mechanically ventilated (MV) patients, but the potential association between ventilatory pressure parameters and AGI grade and their impact on mortality remains unclear. This study aimed to explore the association between ventilatory pressure parameters and AGI grade, and their interaction on all-cause mortality in MV patients. This study was a secondary analysis of a multicenter, prospective, observational study that enrolled adult patients with an expected duration of mechanical ventilation ≥ 48 h from 14 general intensive care units in Zhejiang Province between March and August 2014. The AGI grade was assessed daily on the basis of gastrointestinal symptoms, intra-abdominal pressures, and feeding intolerance in the first week of admission to the ICU. This study included 331 patients (69.2% men; mean age, 64.6 ± 18.9 years). Multivariate regression analysis showed that plateau pressure (Pplat) (OR 1.044, 95% CI 1.009-1.081, P = 0.013), serum creatinine (OR 1.003, 95% CI 1.001-1.006, P = 0.042) and APACHE II score (OR 1.035, 95% CI 1.021-1.072, P = 0.045) were independently associated with global AGI grade III/IV within 7 days of ICU admission. Moreover, global AGI grade (HR 2.228, 95% CI 1.561-3.182, P < 0.001), serum creatinine (HR 1.002, 95% CI 1.001-1.003, P = 0.012) and APACHE II score (HR 1.039, 95% CI 1.015-1.063, P = 0.001) were independently associated with 60-day mortality. In addition, there were significant (P int  ≤ 0.028) interactions of Pplat and DP with AGI grade in relation to 60-days mortality, whereas no interaction (P int  = 0.061) between PEEP and AGI grade on 60-days mortality was observed. In the presence of Pplat ≥ 19 cmH 2 O, the patients with AGI grade III/IV had 60-day mortality rate of 72.2%, significantly higher than those with AGI grade I/II (48.7%, P = 0.018), whereas there were no significant differences (27.9% vs. 33.7%, P = 0.39) in 60-days mortality between AGI grade I/II and III/IV among the patients with Pplat < 19 cmH 2 O. In comparison with Pplat, DP had a similar interaction (P int  = 0.028) with AGI grade on 60-day mortality. Ventilatory pressure parameters (Pplat and DP) are independent risk factors of AGI grade III/IV. Pplat and DP interact with AGI grade on 60-days mortality, highlighting the importance of optimizing ventilatory pressure parameters to improve gastrointestinal function and survival outcomes of MV patients.Trial registration: ChiCTR-OCS-13003824., (© 2024.

Background: Intraperitoneal pressure measurement offers therapeutic and prognostic benefits in predicting leak risks and gastrointestinal symptoms in Peritoneal Dialysis (PD) patients. This systematic review aims to evaluate the prognostic utility of intraperitoneal pressure measurements and different estimated intraperitoneal pressure equations in predicting the risk of non-infectious complications in PD patients., Methods: Databases including MEDLINE, EMBASE and Cochrane were searched up to July 2023. Randomised and non-randomised trials were included, focusing on End-Stage Kidney Disease (ESKD) patients undergoing PD. Primary outcomes were variables associated with intraperitoneal pressure, while secondary outcomes included PD-related non-infectious complications and gastrointestinal symptoms. Data synthesis combined meta-analysis with narrative synthesis. This review has been registered on PROSPERO (CRD42023475138)., Results: Out of 1828 identified studies, 12 were included for systematic review and 10 for meta-analysis. Body Mass Index (BMI) and Body Surface Area (BSA) showed a consistent positive correlation with intraperitoneal pressure (BMI: r = 0.49, 95% CI 0.35-0.61, I 2  = 67.39%, p = 0.003; BSA: r = 0.2, 95% CI 0.08-0.31, I 2  = 14.10%, p = 0.324). Conversely, the association between intraperitoneal pressure and age, intraperitoneal volume, and Charlson Comorbidity Index were less consistent. Subgroup analysis demonstrated an association between higher intraperitoneal pressure in patients with increased BMI and BSA. However, the relationship between intraperitoneal pressure and non-infectious mechanical complications remained inconclusive., Discussion: This review underscores a significant association between intraperitoneal pressure and anthropometric measures (BMI and BSA). The majority of the studies identified included a small sample and considerable bias. However, the association between intraperitoneal pressure and clinically relevant outcomes was not clear., Conclusions: While increasing body mass index and body surface areas are associated with increasing intraperitoneal pressure, the clinical relevance of measuring intraperitoneal pressure in an adult population remains unclear, particularly given the absence of an association with clinically relevant non-infectious outcomes., (© 2024.

Aim: Primary immunodeficiencies (PIDs) are a heterogeneous disorder group characterized by an impaired immune system, leading to an increased susceptibility to infections and a wide range of clinical manifestations, including gastrointestinal (GI) complications. This study aimed to assess the GI manifestations of PID patients and highlight the significance of atypical gastrointestinal symptoms in the early diagnosis of these patients., Methods: A retrospective analysis was conducted on pediatric patients diagnosed with PIDs at Selcuk University Medical Faculty from 2011 to 2021. The study focused on demographic data, clinical presentation, genetic mutations, and GI manifestations, including endoscopic evaluation. Patients were categorized according to the International Union of Immunological Societies (IUIS) PID classifications. Statistical analyses were performed to identify significant associations between PID types and GI manifestations., Results: The cohort comprised 101 patients, with 46% presenting with GI symptoms, including malnutrition and chronic diarrhea, as the most common findings. Primary antibody deficiency (PAD) emerged as the most prevalent PID with GI involvement, followed by combined immunodeficiencies (CID) with associated or syndromic features. Endoscopic evaluations revealed inflammatory bowel disease (IBD)-like colitis in a significant subgroup of patients. The analysis showed that some GI symptoms were more common in specific PID categories, highlighting the importance of early gastroenterological assessment in PID patients., Conclusion: Recognition of common GI symptoms in pediatric patients with PIDs may facilitate early diagnosis and prompt multidisciplinary management, potentially improving patient outcomes. The study highlights the necessity of considering PIDs in diagnosing persistent or severe GI symptoms in children.

Objectives: Extra-osseous (EO) manifestations are poorly characterized in chronic recurrent multifocal osteomyelitis (CRMO). This study aimed to further define the frequency, characteristics and treatment of EO events in CRMO and whether different phenotypes can be distinguished and benefit from special management., Methods: This multicentre retrospective study included CRMO patients followed in several paediatric rheumatology departments in France between 2015 and 2022. EO manifestations were defined as skin lesions, gastrointestinal manifestations, arthritis, enthesitis, sacroiliitis, uveitis, vasculitis and fever. At the last visit, the physician defined CRMO as active in the presence of clinical manifestations including both osseous and EO symptoms., Results: We included 133 patients; 87 (65.4%) were girls and the median age at first symptoms was 9.0 years (interquartile range 7.0-10.0). EO manifestations were described in 90 (67.7%) patients, with a predominance of skin lesions [n = 51/90 (56.7%)], followed by sacroiliitis [n = 38/90 (42.2%)], enthesitis [n = 21/90 (23.3%)], arthritis [n = 14/90 (15.6%)] and gastrointestinal manifestations [n = 6/90 (6.7%)]. The use of non-steroidal anti-inflammatory drugs and bisphosphonates did not differ by the presence or not of EO manifestations. Biologics were taken more frequently by patients with than without EO manifestations (P < 0.001); TNF inhibitors were used in 33 (36.7%) EO-positive patients. Under this treatment, 18 (54.5%) patients achieved complete remission of osseous and EO manifestations. At the last visit, more EO+ than EO- patients were on treatment (P = 0.009), with active disease in 58 (64.4%) patients., Conclusion: The analysis of EO manifestations in CRMO delineates two groups of patients in terms of severity and treatments used. Our study opens up new pathophysiological leads that may underlie the wide range of CRMO phenotypes., (© The Author(s) 2023.

Purpose of Review: This focused, narrative review mostly describes our team's investigations into the potential inflammatory mechanisms that contribute to the development of cancer-related gastrointestinal (GI) mucositis and its associated symptoms. This review summarizes details of our clinical and preclinical findings to test the role of inflammation in the development and occurrence of these cancer-related conditions., Recent Findings: GI mucositis (GIM) is a common, distressing condition reported by cancer patients. GIM is often clustered with other behaviors including fatigue, pain, anorexia, depression, and diarrhea. It is hypothesized that there is a common biologic mechanism underpinning this symptom cluster. Our multi-platform investigations revealed that GIM and its associated cluster of behaviors may be triggered by local inflammation spreading systemically causing pro-inflammatory-mediated toxicities, leading to alterations in immune, metabolic, and nervous system functions and activities. For example, behavioral toxicities related to local irradiation for non-metastatic cancer may be triggered by mGluR5 activation influencing prolonged T cell as well as NF-κB transcription factor activities. Thus, interventions targeting inflammation and associated pathways may be a reasonable strategy to alleviate GIM and its symptom cluster., Summary: GIM may be a sign of a broader systemic inflammatory response triggered by cancer or its treatment. Addressing GIM and its associated symptoms primarily involves supportive care strategies focused on relieving symptoms, promoting healing, and preventing complications., (Copyright © 2024 The Author(s).

Background: Minimal clinically important difference (MCID) is important to establish as a meaningful outcome in research when using patient reported outcome measures (PROMs). We determined the MCID using the distribution-based approach for three measurements used as part of the GALAXY study, which is an observational prospective study on gastrointestinal (GI) symptoms in cystic fibrosis (CF)., Methods: Four hundred and two persons with cystic fibrosis (PwCF) participated in the GALAXY study, all with baseline values available for all questionnaires. Mean age was 20.9 years (2.1- 61.1) with 75 females and 94 males under the age of 18 (42.04 %) and 118 females and 115 males aged 18 or older (57.99 %). MCID was measured for Patient Assessment of Constipation Symptoms (PAC-SYM), Patient Assessment of Upper Gastrointestinal Symptoms (PAGI-SYM), Patient Assessment of Constipation-Quality of Life (PAC-QOL) and their subscales. Two distribution-based approaches, defined as multiplications of the standard deviation (SD) or standard error of the mean (SEM), were used to approximate the MCID., Results: The two distribution-based approaches for determining the MCID estimates produced comparable results in trends in MCIDs across the subscales and total scores. In general, MCID estimates of subscales for all three measurements were higher than their total score MCIDs. The one-half SD- and SEM-based MCID estimates for total scores of each questionnaire are as follows: PAC-SYM: 0.26 and 0.14; PAGI-SYM: 0.32 and 0.15; PAC-QOL: 0.27 and 0.18, respectively., Conclusion: This paper establishes initial MCIDs estimated by the distribution-based approach for the PAC-SYM, PAGI-SYM and PAC-QOL that can now be used to evaluate interventional studies that may impact gastrointestinal symptoms in PwCF., Competing Interests: Declaration of competing interest Dr. Meghana Sathe has received research support from Anagram Therapeutics, Inc and the Cystic Fibrosis Foundation.

Background: This study aimed to investigate the association between intestinal fatty acid-binding protein (I-FABP), acute gastrointestinal injury (AGI) grade, and gastrointestinal (GI) complications after fenestrated or branched endovascular aortic aneurysm repair., Methods: A total of 17 patients undergoing endovascular aortic repair for thoracoabdominal, juxtarenal, suprarenal, or pararenal aneurysm between May 2017 and September 2018 were enrolled. Blood samples were collected preoperatively and during postoperative intensive care. The blood samples were analyzed for I-FABP with enzyme-linked immunosorbent assay. Gastrointestinal function was assessed according to the AGI grade every day during postoperative intensive care., Results: Higher concentrations of I-FABP at 24 hr and 48 hr correlated to higher AGI grade on postoperative days 1, 2, and 3 (P = 0.032 and P = 0.048, P = 0.040 and P = 0.018, and P = 0.012 and P = 0.016, respectively). Patients who developed a GI complication within 90 days postoperatively had a higher overall AGI grade than those who did not develop a GI complication (P < 0.001), as well as higher concentrations of I-FABP at 48 hrs (P = 0.019). Patients developing GI dysfunction (AGI grade ≥2) had a higher frequency of complications (P = 0.009) and longer length of stay in the intensive care unit (P = 0.008)., Conclusions: In patients undergoing endovascular aortic repair for complex aneurysm increased postoperative plasma I-FABP concentrations and postoperative GI dysfunction, evaluated using the AGI grade, were associated with GI complications, indicating that these measures may be useful in the postoperative management of these patients., (Copyright © 2024 The Author(s).

Purpose: Rett syndrome is a rare neurodevelopmental disorder associated with methyl CpG binding protein 2 (MECP2) gene mutations. We aimed to characterize the long-term nutritional and gastrointestinal course of Rett syndrome in a large national patient population., Methods: We conducted a retrospective cohort study of patients followed during 1991-2021 at a national center for Rett syndrome. The data retrieved included clinical features, laboratory and genetic analyses. Continuous anthropometric measurements were calculated for the closest visit to the median ages: 2.5, 7.5, 12.5 and 17.5 years. Kaplan Meier curves were used to describe the appearance of clinical manifestations during the follow up period. Generalized estimating equation models were used to compare repeated measurements., Results: Included were 141 patients (139 females), the median age at the first visit was 3.2 years (interquartile range [IQR] 2.3-5.7), and the median length of follow-up was 94.5 months (IQR 28.6-153.3). Mean weight, height and BMI Z-scores were -1.09, -1.03 and -0.56, respectively, at median age 2.5 years; and deteriorated to -3.95, -3.01 and -1.19, respectively, at median age 17.5 years (P < 0.001). Gastrointestinal features included constipation (47.5%, 67/141) and chewing/feeding difficulties (20%, 28/141) at presentation; and an additional 47 (33.3%) and 24 (17.0%), respectively, during follow up. Twenty-eight patients (20%) developed aerophagia and 44 (31.2%) gastroesophageal reflux. No relation was found between genetic mutation types and clinical manifestations. GI manifestations were more prevalent in patients with typical form of Rett syndrome., Conclusions: Anthropometric parameters were shown to deteriorate with age, regardless of the specific genetic mutation. Chewing/feeding difficulties, constipation and gastroesophageal reflux are common in Rett patients., (© 2024.

Background: Food-related quality of life (FRQoL) measures the impact of diet, eating behaviours and food-related anxiety on quality of life. Patients often view food and eating as central to symptom management. This is the first study to examine FRQoL in patients with inflammatory bowel disease, celiac sprue, achalasia and eosinophilic oesophagitis., Methods: A total of 289 adults aged ≥18 years completed self-report measures evaluating the use of dietary treatment, FRQoL and other psychosocial outcomes. Principal component factor analysis evaluated potential subscales within the Food-Related Quality of Life Scale (FRQoL-29), to date validated only with a total score. Univariate analyses investigated differences in FRQoL based on diagnosis, whereas correlations and hierarchical regression identified relationships between FRQoL and psychosocial outcomes., Results: Factor analysis revealed four subscales within the FRQoL-29, with hypervigilance around eating being the primary driver in total score. Patients reported substantial impacts of FRQoL, with those not using diet therapy scoring significantly higher for FRQoL than those on a diet with and without the support of a registered dietitian (RD). Both social (r = 0.41, p < 0.001) and physical (r = 0.31, p < 0.001) domains of health-related quality of life were higher in patients with greater FRQoL., Conclusion: FRQoL is significantly degraded in patients with organic gastrointestinal illness diseases, and hypervigilance around food appears to contribute most to this. Use of dietary treatment and meeting with an RD were associated with lower FRQoL, though it is unclear if patients sought RD assistance before FRQoL declined. Future studies on the relationship between dietary treatment, RD support and FRQoL are warranted., (© 2024 The Author(s).

We systematically reviewed observational and Mendelian randomization (MR) articles that evaluated the association between obesity and 17 gastrointestinal (GI) diseases to integrate causal and observational evidence. A total of 594 observational studies from 26 systematic reviews and meta-analyses and nine MR articles were included. For every 5 kg/m 2 increase in body mass index (BMI), there was an increased risk of GI diseases ranging from 2% for rectal cancer (relative risk [RR]: 1.02, 95% confidence interval [CI]: 1.01 to 1.03) to 63% for gallbladder disease (RR: 1.63, 95% CI: 1.50 to 1.77). MR articles indicated that risks of developing GI diseases elevated with each 1 standard deviation increase in genetically predicted BMI, ranging from 11% for Crohn's disease to 189% for nonalcoholic fatty liver disease. Moreover, upper GI conditions were less susceptible, whereas hepatobiliary organs were more vulnerable to increased adiposity. Among the associations between obesity and the 17 GI conditions, causal relationships were inferred from only approximately half (10/17, 59%). This study reveals a substantial gap between observational and causal evidence, indicating that a combined approach is necessary to effectively inform public health policies and guide epidemiological research on obesity and GI diseases., (© 2024 The Author(s).

Background and Objectives: Parkinson disease (PD), which is a neurodegenerative disorder, includes several gastrointestinal symptoms that are similar to those of Celiac disease (CD). However, the presence of celiac antibodies in PD patients has not yet been studied. Our aim in this study is to compare anti-transglutaminase (ATA) and antigliadin antibodies (AGA) as well as gastrointestinal symptoms and nutrition habits between patients with Parkinson's disease (PD) and healthy controls., Methods and Study Design: Serum AGA IgG and IgA and the ATA antibodies IgA and IgG were studied in 102 PD patients and 91 healthy controls. Gastrointestinal symptoms, specifically constipation, were investigated using the gastrointestinal system rating scale (GSRS) and the constipation rating scale (CRS). Dietary habits were also investigated and compared between the groups., Results: No significant differences were found between the two groups in terms of celiac antibodies. As expected, the hypokinetic GSRS and CRS scores were significantly higher in the PD group (p<0.001). Dietary habits, especially carbohydrate-rich diets, had a negative impact on gastrointestinal symptoms in the PD patients., Conclusions: Studies have suggested a connection between PD and CD, which infers a probable non-celiac gluten intolerance and the need to offer PD patients an elimination diet. However, the results of our study did not support any link between celiac antibodies and PD. Notwithstanding, the negative impact of a carbohydrate-rich diet in PD patients still leaves a question regarding gluten sensitivity in these patients., Competing Interests: The authors declare no potential conflict of interest

Williams syndrome (WS) is a multi-system condition caused by the deletion of 25-27 coding genes on human chromosome 7. Irritability, gastrointestinal (GI) reflux and slow growth are commonly reported in infants with WS, but less data exist regarding GI concerns in older children and adults with the condition. This study evaluates 62 individuals with WS (31 children aged 3-17, and 31 adults aged 18-62) as well as 36 pediatric and adult controls to assess current and historical rates of common GI symptoms. Data were evaluated using a regression model including age, sex, self-reported race, and diagnosis. Symptoms including food intolerance, reflux, dysphagia, choking/gagging, vomiting, constipation, bloating, diarrhea, hematochezia, rectal prolapse, abdominal pain, and weight loss are more common in those with WS relative to controls. In addition, people with WS utilize more GI medications, specialty care, procedures, and supplemental feeds. Among those with WS, symptoms were present at similar rates in children and adults, except for diverticular disease, which was not noted until adulthood. GI symptoms are frequent in people with WS and serve as a significant source of morbidity., (Published 2024. This article is a U.S. Government work and is in the public domain in the USA.

Background: The delivery of safe drinking water has high public health relevance, as reflected in the Sustainable Development Goals (SDG6). Several precautionary actions have reduced the burden associated with infectious diseases in high-income countries; however, pollution in source waters, inadequate disinfection, and premise plumbing, along with an increased awareness that intrusion in the drinking water distribution system, represents risk factors for gastrointestinal illness linked to consume of drinking water. Sporadic cases of waterborne infections are expected to be underreported since a sick person is less likely to seek healthcare for a self-limiting gastrointestinal infection. Hence, knowledge on the true burden of waterborne diseases is scarce. The primary aim with the present study was to estimate the risk of gastrointestinal illness associated with drinking tap water in Norway., Methods: We conducted a 12-month prospective cohort study where participants were recruited by telephone interview after invitation based on randomised selection. A start up e-survey were followed by 12 monthly SMS questionnaires to gather information on participants characteristics and drinking tap water (number of 0.2L glasses per day), incidence, duration and symptoms associated with gastrointestinal illness. Associations between the exposure of drinking tap water and the outcome of risk of acute gastrointestinal illness (AGI) were analysed with linear mixed effects models. Age, sex, education level and size of the drinking water supply were identified as potential confounders and included in the adjusted model., Results: In total, 9,946 persons participated in this cohort study, accounting for 11.5% of all invited participants. According to the data per person and month (99,446 monthly submissions), AGI was reported for 5,508 person-months (5.5 per 100 person-months). Severe AGI was reported in 819 person-months (0.8 per 100 person-months). Our study estimates that 2-4% of AGI in Norway is attributable to drinking tap water., Conclusions: This is the largest cohort study in Norway estimating the burden of self-reported gastrointestinal infections linked to the amount of tap water drunk in Norway. The data indicate that waterborne AGI is not currently a burden in Norway, but the findings need to be used with caution. The importance of continued efforts and investments in the maintenance of drinking water supplies in Norway to address the low burden of sporadic waterborne cases and to prevent future outbreaks needs to be emphasised., (© 2024.

Background/purpose: Limited studies have addressed the exacerbation of symptoms and long COVID in inflammatory bowel disease (IBD) patients following non-severe COVID-19 infection, particularly with post-COVID-19 vaccination. We aim to investigate factors associated with exacerbated gastrointestinal symptoms (EGS) and long COVID in IBD patients with non-severe COVID-19, which is most common situation in daily practice., Methods: This is an observational study by multiple centers in Taiwan from May 2020 to March 2023. We collected clinical manifestation, data, and medication information from IBD patients with non-severe COVID-19. EGS was defined as increased frequency of diarrhea, bloody stool, and abdomen pain within 14 days after SARS-COV-2 infection. Long COVID was defined following the guidelines of the World Health Organization., Results: Out of 90 patients, most of them (88.9%) received at least standard two doses of COVID-19 vaccination and the majority (87.8%) were mild diseases of COVID-19.30% of patients experienced EGS during COVID-19 with higher ESR levels serving as a predictive factor (Odds ratio: 3.6, 95% confidence interval: 1.2-10.5, P = 0.02). 38.1% of those patients developed long COVID. The patients who experienced EGS during COVID-19 and with a history of longer IBD duration showed a significant association with long COVID (p = 0.03 and p = 0.02)., Conclusion: Our study revealed that EGS and long COVID occurred in one third of IBD patients with non-severe COVID-19, even though most of them had received the standard plus booster vaccination. We identified associated factors for EGS and long COVID, emphasizing the importance of post-COVID-19 follow-up in IBD patients., Competing Interests: Declaration of competing interest A conflict of interest occurs when an individual's objectivity is potentially compromised by a desire for financial gain, prominence, professional advancement or a successful outcome.

Objectives: The gastrointestinal tract (GIT) is frequently involved in systemic sclerosis (SSc) and is responsible for alteration of quality of life. Many complications can occur, including chronic intestinal pseudo-obstruction, digestive haemorrhage and small-intestinal bacterial overgrowth. Since early development of organ failure is associated with poor prognosis, we need to identify risk factors associated with severe GIT involvement to prevent severe forms of the disease., Methods: We conducted an observational prospective study, which included 90 SSc patients from December 2019 to September 2021. We collected questionnaires about digestive manifestations and quality of life, blood and stool samples, and performed imaging. At inclusion and throughout the study we assessed the occurrence of malnutrition and severe GIT disorders. We performed statistical analysis to highlight eventual risk factors associated with digestive manifestations, including hierarchical cluster analysis., Results: A majority of our patients had gastro-oesophageal manifestations (93.3%), followed by intestinal manifestations (67.8%) and anorectal manifestations (18.9%). We found a correlation between anorectal disorders and cardiac disease, and between gastro-oesophageal involvement and impaired pulmonary function tests. Smoking was significantly associated with occurrence of severe GIT disorders. Malnutrition was frequent and associated with more cardiac and pulmonary disease. Cluster analysis identified three groups of patients, including one cluster with cardiac and digestive involvement., Conclusions: GIT manifestations are frequent and severe in SSc. Smoking appears to be associated with severe disease. Anorectal manifestations may be associated with cardiac disease, but we need more studies to validate these results.

Background and Study Aims: Gastrointestinal adverse reaction to food (GARF) is reported frequently in the general population and even more in patients with disorders of the gut brain axis. However, there is a significant difference between self-reported and objective proven GARF. The aim of the study was to characterize a mucosal correlate of GARF by endoscopic confocal laser endomicroscopy (eCLE) with duodenal food challenge (DFC)., Patients and Methods: In an observational and proof of concept study we evaluated 71 patients with disorders of the gut brain axis without (group I, n=19) and with (group II, n=52) GARF by eCLE and DFC. Spontaneous and food induced transfer of fluorescein into duodenal lumen was detected 10 minutes following intravenously application of fluorescein and 10 minutes after DFC., Results: According to Rom IV, the patients (group I/II) could be classified as irritable bowel syndrome (IBS) 32%/31%, functional abdominal pain without changes in bowel movement 47 %/48 %, functional abdominal bloating/distension 0 %/10 %, functional diarrhea 5 %/ 2 %, and unspecified functional bowel disorder 16 %/10 %, respectively. 21 %/27 % of the patients responded with a fluorescein leakage into the duodenal lumen before and 74 %/69 % following to DFC. Frequency rank order of food components that induced a response were soy (55.5 %/60 %), wheat (60 %/45.5 %), egg (35.7 %/8.3), milk (30 %/18.2 %) and yeast (10 %/6.6 %), respectively. Histology of duodenal biopsies, number, form and distribution of intraepithelial lymphocytes and mucosal mast cells as well as mast cell function were normal. Overall, 14 %/79 % reported main symptom benefit following a food exclusion therapy according to eCLE and DFC that was significant different between the groups., Conclusion: The results of our study indicate that eCLE with DFC is a technique to clinically evaluate patients with disorders of the gut brain axis and GARF resulting in a high proportion of patients reporting symptom benefit upon food exclusion dietary advice focussed on the results of eCLE., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

In recent decades, the patient survival is increased due to advances in intensive care units and development of modern mechanic ventilators. Unfortunately, it is not always possible to wean these children from mechanical ventilation. Recently, after placement a tracheostomy tube, these children can be supported at home with noninvasive or invasive mechanical ventilation. Most of the children who need ventilation support at home have neurological impairment. The nutritional issues and gastrointestinal (GI) complications are well defined in critically ill patients, but there are very limited studies on children with tracheostomy. Considering that majority of the patients have neuromuscular disorders, the nutritional and GI problems of the children with tracheostomy are discussed in light of the knowledge of critically ill patients., (© 2023 The Authors.

Background: The search for factors beyond the radiotherapy dose that could identify patients more at risk of developing radio-induced toxicity is essential to establish personalised treatment protocols for improving the quality-of-life of survivors. To investigate the role of the intestinal microbiota in the development of radiotherapy-induced gastrointestinal toxicity, the MicroLearner observational cohort study characterised the intestinal microbiota of 136 (discovery) and 79 (validation) consecutive prostate cancer patients at baseline radiotherapy., Methods: Gastrointestinal toxicity was assessed weekly during RT using CTCAE. An average grade >1.3 over time points was used to identify patients suffering from persistent acute toxicity (endpoint). The microbiota of patients was quantified from the baseline faecal samples using 16S rRNA gene sequencing technology and the Ion Reporter metagenomic pipeline. Statistical techniques and computational and machine learning tools were used to extract, functionally characterise, and predict core features of the bacterial communities of patients who developed acute gastrointestinal toxicity., Findings: Analysis of the core bacterial composition in the discovery cohort revealed a cluster of patients significantly enriched for toxicity, displaying a toxicity rate of 60%. Based on selected high-risk microbiota compositional features, we developed a clinical decision tree that could effectively predict the risk of toxicity based on the relative abundance of genera Faecalibacterium, Bacteroides, Parabacteroides, Alistipes, Prevotella and Phascolarctobacterium both in internal and external validation cohorts., Interpretation: We provide evidence showing that intestinal bacteria profiling from baseline faecal samples can be effectively used in the clinic to improve the pre-radiotherapy assessment of gastrointestinal toxicity risk in prostate cancer patients., Funding: Italian Ministry of Health (Promotion of Institutional Research INT-year 2016, 5 × 1000, Ricerca Corrente funds).

Background: Duchenne's muscular dystrophy (DMD) is a severe type of hereditary, neuromuscular disorder caused by a mutation in the dystrophin gene resulting in the absence or production of truncated dystrophin protein. Conventionally, clinical descriptions of the disorder focus principally on striated muscle defects; however, DMD manifestations involving gastrointestinal (GI) smooth muscle have been reported, even if not rigorously studied., Purpose: The objective of the present review is to offer a comprehensive perspective on the existing knowledge concerning GI manifestations in DMD, focusing the attention on evidence in DMD patients and mdx mice. This includes an assessment of symptomatology, etiological pathways, and potential corrective approaches. This paper could provide helpful information about DMD gastrointestinal implications that could serve as a valuable orientation for prospective research endeavors in this field. This manuscript emphasizes the effectiveness of mdx mice, a DMD animal model, in unraveling mechanistic insights and exploring the pathological alterations in the GI tract. The gastrointestinal consequences evident in patients with DMD and the mdx mice models are a significant area of focus for researchers. The exploration of this area in depth could facilitate the development of more efficient therapeutic approaches and improve the well-being of individuals impacted by the condition., (© 2024 John Wiley & Sons Ltd.)

Background: Neurological impairment (NI) relates to disorders of the central nervous system. The specific aetiology of NI varies but includes genetic, congenital abnormalities or brain injury. In children with severe NI, feeding impairments can lead to undernutrition, and some children require a feeding tube. Although tube feeding improves overall nutritional status, it has also been associated with excess body fat. Commercially available enteral formulas that are low in energy, hydrolysed and nutritionally adequate for protein and micronutrients are available to mitigate gastrointestinal symptoms and obesity., Methods: This is a retrospective multicentre study of children who attended NI clinics between January 2022 and July 2023. Data were collected before and 1 month after receiving a low-energy, partially hydrolysed enteral formula (0.6 kcal/mL) on demographic data (age, sex, ethnicity and NI diagnosis), anthropometric measurements (weight, height, weight-for-age Z-score, height-for-age Z-score, body mass index [BMI] Z-score) and feed regimen (feed volume, total fluids and type of formula/supplements)., Results: Dietitians collected data on 28 children, the median age was 7 years (interquartile range [IQR] 3, 8). The most frequently recorded NI was cerebral palsy, in 13 of 28 children (48%). Before the formula switch, the most frequently reported gastrointestinal symptom was constipation, in 13 of 28 children. Within 1 month of switching to a low-energy, hydrolysed formula, 10 of the 13 (77%) children reported an improvement in constipation. Before the formula switch, all 28 children were experiencing excessive weight gain. After the formula was switched to low-energy, hydrolysed formula, dietitians reported that 20 of the 28 (76%) children's weight either stabilised or reduced after 1 month. There was no statistically significant difference in weight-for-age Z-score or BMI Z-scores postswitch of formula (p-value 0.1 and 0.09, respectively). Fibre intake increased significantly from 3.3 to 8.1 g/day (p-value < 0.01) after formula switch. The number of children whose feed regimens were simplified after switching to a low-energy, partially hydrolysed formula was 24 of 28 (91%)., Conclusions: Children with an NI who have gastrointestinal symptoms may benefit from a low-energy, hydrolysed enteral formula to maximise feed tolerance and promote healthy weight gain. In addition, changing to a low-energy, hydrolysed formula may simplify feed regimens by eliminating the need for additional electrolytes, multivitamins and fluid boluses. Healthcare professionals should be knowledgeable about the effectiveness and availability of a low-energy, hydrolysed formula., (© 2024 The Authors.
