RESUMEN
Objectives: To gather initial data on the effectiveness and tolerability of the addition of Ondansetron to bowel preparation regimens to justify a funded, larger, placebo-controlled study. Methods: Design, Setting, and Participants:: A total of 41 pediatric and young adult (age 2-22) patients participated in a single center, open label, parallel randomized trial, with simple randomization. All patients were recruited as outpatients, and all procedures occurred as outpatient procedures, with both recruitment and procedures occurring at a low-resource urban academic medical center in Brooklyn.Interventions and Outcome Measures:: The intervention studied was a single dose of oral-dissolving tablet Ondansetron provided before initiation of bowel preparation using a standardized prep of Polyethylene Glycol 3350 and Bisacodyl. There were 2 arms, a study arm using typical preparation (Polyethylene Glycol 3350 and Bisacodyl) and Ondansetron, and a control arm (Polyethylene Glycol 3350 and Bisacodyl). Patients received standard weight-based dosing. The primary outcome measure assessed was the Boston Bowel Preparation Scale (BBPS) to assess efficacy of preparation. Secondary objectives included evaluation of patient satisfaction via a survey answered by each patient. The questionnaire assessed the presence of the following symptoms during bowel prep: abdominal pain, nausea, bloating, vomiting, scale of ease/difficulty, and if the entire bowel prep was completed. Results: No benefit to BBPS from the addition of Ondansetron to bowel preparation was observed. Statistically significant improvement in reports of abdominal pain (35% decrease in Ondansetron arm) was noted with a P = 0.019. No statistically significant improvement was noted in other symptoms although all domains showed nonsignificant improvement in the Ondansetron arm. Conclusion: No benefit to efficacy of preparation as measured by the BBPS was observed. A single dose of Ondansetron before bowel preparation reduced reports of abdominal pain by 35%, with other symptomatic improvements suggesting possible improvements to be confirmed by a higher-powered study. Trial registration: NCT05439772.
RESUMEN
ABSTRACT: In recent years, multiple advances have been made in the care, diagnosis, and mechanistic understanding of acute gastroenteritis (AGE). In this review, we discuss the current state of the art of diagnosis and management, as well as how changes in practice can improve care and decrease costs. We will discuss present study demonstrating the effect of AGE on the microbiome and how that may be linked to secondary effects or long-term changes. We will explore the use of novel technologies to further our capacity to understand how gastrointestinal infections occur and promulgate. Finally, will discuss advances in our understanding of how gastrointestinal infections capacitate other changes such as post-viral motility or other post viral intestinal dysfunction.

Eosinophilic esophagitis (EoE), an eosinophil predominant, TH2-mediated condition increasing in prevalence in pediatric and adult populations, is typically treated with dietary manipulations to avoid triggering antigens. However, identifying specific dietary causes remains a persistent challenge, and restrictive diets are burdensome. Total dietary modification using amino acid-based formula does not always produce symptomatic or histologic resolution, suggesting that exposure to ingested aeroallergens drives their disease. EoE patients demonstrate symptomatic exacerbation from July to September correlating with higher grass and ragweed pollen counts. We present a 7-year-old tracheostomy- and gastrostomy-dependent girl who was found on surveillance endoscopy to have profound eosinophilic infiltration throughout the esophagus with inflammatory changes including basal cell hyperplasia on histology. She responded partially to topical corticosteroid therapy with fluticasone and had complete resolution of esophageal eosinophilic infiltrate with subcutaneous dupilumab.
RESUMEN
In addition to the severe impact of acute respiratory disease during the SARS-CoV-2 pandemic, the issue of "Long COVID" illness has impacted large numbers of patients following the initial infection. Wide ranges of Long Covid incidence have been reported, ranging from 30 to 87%. Long COVID has a variety of clinical manifestations, including gastrointestinal symptoms. Here, we report a case of persistent abdominal pain, 3 months following a SARS-CoV-2 diagnosis, associated with chronic colonic inflammation and the presence of mucosal SARS-CoV-2 virions.
