Approximately 20% of patients with ulcerative colitis (UC) develop acute severe UC (ASUC), for which intravenous systemic steroid therapy and possibly infliximab-based rescue therapy are generally imposed. However, there are no significant guideline recommendations on ASUC regarding vedolizumab as an alternative in this setting. A case report was presented where a patient with steroid-dependent UC developed ASUC induced by second-line chemotherapy. Treatment with intravenous methylprednisolone was imposed, but there was no reduction in bowel movements in the days following admission. Rescue therapy with infliximab was contraindicated because of the oncologic history. Surgical consultation, contraindicated colectomy, and administration of vedolizumab 300 mg were initiated. After infusion with vedolizumab, there was a significant reduction in bowel movements starting the day after infusion until normalisation of bowel movements within three days and the concomitant normalisation of inflammatory indices. The patient is currently in clinical remission, on therapy with vedolizumab 108 mg subcutaneously every two weeks, and is in oncologic follow-up for pulmonary neoplasm. This case highlights the novel potential of vedolizumab as a possible rescue therapy in ASUC, especially in special populations, where it may offer a better safety profile. Although cyclosporine and infliximab still represent the mainstays of salvage therapy for steroid-refractory ASUC, new therapeutic agents may also be effective, such as vedolizumab, ustekinumab, and anti-Janus kinase agents.

Background: Technological advances in pediatric gastrointestinal (GI) endoscopy require highly specialized physicians. Therefore, proper training is fundamental. The aim of this study was to assess the level of competence of pediatric surgery residents to determine areas that should be addressed to design better training programs focused on pediatric GI endoscopy. Methods: An observational study was performed on all Italian pediatric surgery trainees that concluded the training program by the end of 2021, who were asked to answer a questionnaire about the quality of the GI endoscopy education received during their 5 years of residency. Results: 12 out 14 (86%) pediatric surgery trainees answered the questionnaire. A total of 50% (6/12) of the trainees declared they were interested in pediatric GI endoscopy, and 42% (5/12) said that they would be interested in dedicating themselves to this discipline in the future. Only 33% (4/12) of them were in a center equipped with endoscopy simulators. Among them, 17% (2/12) never took part in GI endoscopic procedures while working in centers in which GI endoscopy is performed exclusively by pediatric gastroenterologists, 25% (3/12) had never performed GI endoscopic procedures as a first operator and 17% (2/12) not even as assistant. Overall, 50% (6/12) were not satisfied with the level of education received and only 17% (2/12) declared that they felt confident enough to perform routine endoscopies alone. Conclusions: Our study highlights great inhomogeneity between different schools and some important failings. Better programs should be designed to educate proficient pediatric GI endoscopists.

The COVID-19 pandemic caused by the SARS-CoV-2 virus has led to significant global health implications. Although the respiratory manifestations of COVID-19 are widely recognized, emerging evidence suggests that the disease may also significantly affect the gut microbiota, the intricate community of bacteria that lives within the gastrointestinal system. This extensive article intends to investigate the impact of COVID-19 on the gut microbiota, examining the underlying mechanisms, clinical implications, and potential therapeutic interventions. Understanding the complex interactions between COVID-19 and the gut microbiota will help us to gain valuable insights into the broader consequences of this viral infection on human health.

This study aimed to investigate the relationship between chronic kidney disease (CKD) and different gastric diseases by conducting a population-based retrospective analysis using National Inpatient Sample (NIS) data. A total of 7,159,694 patients diagnosed with gastric diseases with or without CKD were included, and the diagnoses of gastritis, gastric polyps, peptic ulcer disease (PUD), and Helicobacter pylori infection were based on ICD-10-CM codes. The study found a higher prevalence of gastritis and gastric polyps in patients with CKD compared to patients without CKD, especially in the late stages of CKD. After adjustment, patients with CKD also had a higher risk of developing these gastric diseases than patients without CKD. However, there was no significant association between all stages of CKD and PUD or Helicobacter pylori infection. These results underscored the importance of monitoring gastric health in patients with CKD. Full article

Metoclopramide has been the cornerstone of gastroparesis management for the past 40 years as it is the only FDA-approved medication for gastroparesis. Other medications such as erythromycin and domperidone have been used off-label with variable efficacy. Historically, metoclopramide has been used in oral, intravenous, and subcutaneous formulations. It is an antiemetic and prokinetic medication that acts through the inhibition of central (chemoreceptor trigger zone) and peripheral dopaminergic and serotogenic receptors. Due to its antidopaminergic effects, extrapyramidal symptoms have been reported, with the most feared adverse event being tardive dyskinesia. Subsequently, the FDA issued a metoclopramide black box warning label in February 2009 due to its risk of causing tardive dyskinesia, which can be irreversible. The incidence and prevalence of tardive dyskinesia among metoclopramide users have been variable in different studies. However, upon review of the current literature, the true prevalence of tardive dyskinesia seems to be lower than previously thought. This review will focus on metoclopramide and the extrapyramidal symptoms associated with its use. Full article

Alarm symptoms are widely used in pediatric gastroenterology to discern when abdominal pain needs further workup. Despite wide use, the data supporting the validity of these symptoms are not well established. This study explored one alarm symptom—nighttime waking with pain—and its associations with histologic inflammation of the upper gastrointestinal tract, psychological dysfunction, and disordered sleep. This retrospective study evaluated 240 patients with abdominal pain-related disorders of the gut–brain axis (AP-DGBI). Patients underwent questionnaires related to sleep disturbance, behavioral assessment, and gastrointestinal symptoms, including Rome IV criteria for AP-DGBI. Routine upper endoscopy with standardized biopsies was performed in 205 patients. Endoscopy results showed no association between esophageal, gastric, or duodenal histologic inflammation and nighttime waking with pain. Nocturnal pain was associated with increased scores for both psychological and sleep disorders, including social stress, depression, disorders of initiation and maintenance of sleep (DIMS), disorders of daytime somnolence (DOES), and sleep hyperhidrosis (SHY). This study concluded that nocturnal pain is not a reliable predictor of upper gastrointestinal inflammation but may be a prognosticator for psychological distress and sleep disturbances.

Gut dysbiosis presents in many digestive diseases. The aim of this study is to investigate the composition of the gut microbiota and its metabolic activity in patients with diarrhea-predominant irritable bowel syndrome combined with functional dyspepsia (I + D). This study included 60 patients with I + D and 20 healthy controls. Gut microbiota composition was studied using 16S rRNA gene sequencing. The short-chain fatty acids (SCFAs) spectrum was determined via gas–liquid chromatography. Patients with I + D had an increase in the abundance of Holdemanella, Erysipelotrichaceae, Erysipelotrichales, Prevotellaceae, Agathobacter, Slackia, Lactococcus, Pseudomonadaceae, Stenotrophomonas, Xanthomonadaceae, Rhizobiaceae, Erysipelatoclostridiaceae, Lachnospiraceae, and other taxa in addition to a decrease in the abundance of Frisingicoccus, Ralstonia, Burkholderiaceae, Hungatella, Eisenbergiella, Parabacteroides, Peptostreptococcaceae, Merdibacter, Bilophila, Rikenellaceae, Tannerellaceae, Bacteroidaceae, and Flavonifractor in comparison to controls. Patients with I + D showed significantly higher total SCFA content in feces; increased absolute content of acetic acid, propionic acid, butyric acid, and isoacids; and a significant negative shift in the anaerobic index. The relative levels of the main SCFAs and isoacids in the patient group did not differ significantly from those in the control group. The fecal acetate and isoacid levels correlated with the severity of diarrhea. The fecal butyrate level correlated with the severity of flatulence. Full article

Being two immune-mediated diseases (IMIDs), the association between multiple sclerosis (MS) and inflammatory bowel disease (IBD) is plausible, but data in the literature are conflicting. The aim of our study was to evaluate the possible association between IBD and MS in a cohort of patients with IBD. In a retrospective study, we examined the medical records of 5739 patients with a confirmed diagnosis of IBD followed in our clinic between 1978 and 2022. Among these patients, we identified 14 with MS, with a prevalence of 0.24%. The reported prevalence of MS in the general population in Northern Italy in 2021 was 0.18% (p = 0.24). For each of the patients with MS identified, more than ten patients without MS were analyzed. The 14 MS cases were then compared with 342 controls. From the 14 patients with MS, 12 (85.7%) were female and 2 (14.3%) were male, while in the control group, 158 (46.2%) were female and 184 (53.8%) were male (p = 0.004). As for therapy, significant differences were found in mesalazine (5 (41.7%) cases vs. 317 (92.7%) controls, p < 0.0001) and anti-TNF treatment (0% cases vs. 26.6% controls, p = 0.03, respectively) at the time of MS diagnosis. Moreover, a Kaplan–Meier curve analysis showed that the 20-year survival probability was 98.4% for patients with IBD, while for patients diagnosed with MS and IBD it was 82.1% (p = 0.02). In conclusion, patients with IBD have a similar risk of developing MS compared to the general population, but female sex appears to increase the risk. Indeed, life expectancy at 20 years for patients with IBD and MS is lower than for patients with IBD alone. Full article

Background: Anastomotic leakage (AL) is one of the most feared complications in colorectal cancer (CRC) surgery. Although many series have reported the general risk factors for AL, published studies focusing on ileocolic anastomosis are scarce. The main aim of this study was to identify potential risk factors associated with ileocolic anastomosis dehiscence in surgery for CRC. Methods: A total of 188 patients who underwent primary ileocolic anastomosis after elective CRC surgery in Braga’s Hospital from November of 2018 to February of 2022 were included. A multivariate logistic regression analysis was carried out to identify independent risk factors for AL. Results: AL occurred in 13 patients (6.9%), and about three-fourths of these patients required surgical re-intervention. The mortality rate was 5.3%. Diabetes mellitus, ASA score of ≥3, laparotomy or conversion to laparotomy approach, postoperative blood transfusion, and postoperative hypoalbuminemia were associated with an increased risk of AL. In the multivariable analysis, postoperative hypoalbuminemia (p = 0.018; OR: 0.281; CI: 0.098; 0.806) and shorter operating time (p = 0.038; OR: 0.985; CI: 0.972; 0.999) were independent risk factors for AL. Conclusions: Postoperative hypoalbuminemia and shorter operating time are independent risk factors for AL after ileocolic anastomosis. Full article

Functional gastrointestinal disorders (FGIDs) are characterised by recurring gastrointestinal symptoms that are not secondary to organic disease. FGIDs may cause reduced quality of life, with approximately 22% of children experiencing at least one FGID. This study aimed to assess FGID prevalence among children attending a tertiary care hospital in New Zealand (NZ). Methods: Children aged ≥ four years were prospectively recruited from Christchurch Hospital, NZ. Data were collected on demographics, medical history, gastrointestinal symptoms (Rome IV), and quality of life (EQ-5D-Y). An analysis was carried out using analysis of variance and the chi-squared test of independence. Results: The cohort included 156 children, with a mean age of 9.5 years (SD 3.3), 56% male. According to the Rome IV criteria, 29% experienced at least one FGID, most commonly functional constipation and functional dyspepsia. FGID symptoms were associated with Māori ethnicity (p = 0.012) and parental FGID (p < 0.001). Quality of life was lower in the FGID group in the domain ‘Feeling worried, sad, or unhappy’ (p = 0.002). Conclusion: the association of FGIDs with worse quality of life, in particular relating to worry and sadness, should highlight the importance of providing support to school age children experiencing FGID symptoms.

The paper reviews some of the mechanisms implicated in hepatotoxicity, which is induced by an excess of lipids. The paper spans a wide variety of topics: from the molecular mechanisms of excess lipids, to the therapy of hyperlipidemia, to the hepatotoxicity of lipid-lowering drugs. NAFLD is currently the leading cause of chronic liver disease in Western countries; the molecular mechanisms leading to NAFLD are only partially understood and there are no effective therapeutic interventions. The prevalence of liver disease is constantly increasing in industrialized countries due to a number of lifestyle variables, including excessive caloric intake, unbalanced diet, lack of physical activity, and abuse of hepatotoxic medicines. Considering the important functions of cell death and inflammation in the etiology of the majority, if not all, liver diseases, one efficient therapeutic treatment may include the administration of hepatoprotective and anti-inflammatory drugs, either alone or in combination. Clinical trials are currently being conducted in cohorts of patients with different liver diseases in order to explore this theory. Full article

Definitive data on the incidence rate of ventilator-associated pneumonia (VAP) in COVID-19 are still lacking, ranging from 29 to 58%. To date, most of the existing literature refers to patients who are not subjected to VAP prevention with selective decontamination of the digestive tract (SDD). We retrospectively collected data on all COVID-19 patients admitted to our ICU during the second phase of the pandemic with the aim of assessing the occurrence of VAP and the related mortality at 30 days and comparing our findings with the available literature. Of 213 patients, only 74 were eligible for the analysis. An incidence of 6.90 VAP per 1000 days of mechanical ventilation was detected. Apart from a smoking habit (0% vs. 10%, p < 0.005) and diabetes (14% vs. 54%, p = 0.026), patients who developed VAP did not differ significantly from those who did not regarding comorbidities, steroid use, and the severity of COVID-19. VAP were predominantly caused by mono-microbial Gram-negative or fungal infections. Mortality was significantly higher in those who developed VAP (86 vs. 33%, p = 0.002). Our evidence aligned with the available literature in assuming a possible role of SDD in reducing the incidence of VAP in COVID-19 patients, with a possible impact on related mortality and costs.

Like the majority of non-communicable diseases that have recently gained attention, functional gastrointestinal (GI) disorders (FGID) in both children and adults are caused by a variety of medical conditions. In general, while it is often thought that common conditions such as obesity may cause other problems, for example, asthma or mental health issues, more consideration needs to be given to the possibility that they could both be brought on by a single underlying problem. Based on the variations in non-communicable disease, in recent years, our group has been revisiting the exact role of the intestinal microbiome within the Vertebrata. While the metabolic products of the microbiome have a role to play in the adult, our tentative conclusion is that the fully functioning, mutualistic microbiome has a primary role: to transfer antigen information from the mother to the neonate in order to calibrate its immune system, allowing it to survive within the microbial environment into which it will emerge. Granted that the microbiome possesses such a function, logic suggests the need for a robust, flexible, mechanism allowing for the partition of nutrition in the mature animal, thus ensuring the continued existence of both the vertebrate host and microbial guest, even under potentially unfavourable conditions. It is feasible that this partition process acts by altering the rate of peristalsis following communication through the gut–brain axis. The final step of this animal–microbiota symbiosis would then be when key microbes are transferred from the female to her progeny, either live offspring or eggs. According to this scheme, each animal inherits twice, once from its parents’ genetic material and once from the mother’s microbiome with the aid of the father’s seminal microbiome, which helps determine the expression of the parental genes. The key point is that the failure of this latter inheritance in humans leads to the distinctive manifestations of functional FGID disorders including inflammation and gut motility disturbances. Furthermore, it seems likely that the critical microbiome–gut association occurs in the first few hours of independent life, in a process that we term handshaking. Note that even if obvious disease in childhood is avoided, the underlying disorders may intrude later in youth or adulthood with immune system disruption coexisting with gut–brain axis issues such as excessive weight gain and poor mental health. In principle, investigating and perhaps supplementing the maternal microbiota provide clinicians with an unprecedented opportunity to intervene in long-term disease processes, even before the child is born.

A retrospective analysis of urine culture results was conducted for adult patients treated between 1 January 2017 and 31 December 2021 at the Department of Gastroenterology in Rzeszow (southern Poland). A total of 102 patients were sampled for microbiological tests during the analyzed period, with microbial growth found in 30 samples. The purpose of our study was to determine the predominant bacterial species present in the urine of patients hospitalized in the Department of Gastroenterology, as well as their drug susceptibility. The data obtained from medical records included, for example, urine culture results and the antibiotic susceptibility of the isolated microorganisms. The material for the study was collected according to the current procedures. During the analyzed period, urine was collected from a total of 102 patients, and 30 positive samples were found. The predominant pathogen was Escherichia coli (n = 10 (33.33% of all positive results), p < 0.001); the second most common microorganism was Enterococcus faecalis (n = 5 (16.67% of all positive results), p < 0.001). In vitro susceptibility testing showed E. coli, ESBL (ESBL strain with extended-spectrum beta-lactamase) (n = 2 (6.67% of all positive results), p = 0.055) and Klebsiella pneumoniae, ESBL (n = 3 (10% of all positive results), p = 0.005). Urinary tract infection (UTI) was an extremely common problem. Full article

Background: For children with inflammatory bowel disease (IBD), understanding their condition may lead to better outcomes. Knowledge assessment is imperative to identify where education may be required. An IBD knowledge assessment tool (IBD-KID2) is available in English; the aim of this study was to translate IBD-KID2 in to Italian and assess its validity/reliability among children with IBD. Methods: IBD-KID2 has fifteen items, scoring one point per correct answer. IBD-KID2 items were assessed for cultural comprehension/relevance by Italian gastroenterologists using a content validity index; those items with a maximum score proportion <0.78 were reviewed. IBD-KID2 was then translated using ‘forward–backward’ process and reviewed for content/meaning. A prospective study among Italian children with IBD enabled score comparisons with established populations (z test), and reliability was assessed using test–retest completion (Pearson correlation (r), paired t-test). Results: Twenty-five children participated: 16 (64%) male, mean age 14.9 years (SD2.4), Crohn’s disease 13 (52%). The mean IBD-KID2 score was 8.8 (SD2.8), with no association with independent variables. Test–retest showed strong correlation between scores (r = 0.78, p < 0.001), with no mean difference (p = 0.39). Comparison with other pediatric IBD populations (NZ/Australia/Canada) showed no score difference (p = 0.62, CI −0.9 to 1.5). Conclusions: The translation of IBD-KID2 to Italian used a rigorous methodology. Scores showed the translated tool has equivalence and generalizability to Italian children with IBD. Full article
