Faculty, Staff and Student Publications

BACKGROUND: Inflammatory bowel disease is an inflammatory disorder that primarily impacts the gastrointestinal tract, leading to malnutrition and chronic microscopic intestinal blood loss. Uncontrolled systemic inflammation can impact other parts of the body, known as extraintestinal manifestations. Up to 25% of patients with inflammatory bowel disease are reported to have these complications in their skin, joints, bones, eyes, liver, lung, and pancreas (Rogler et al. in Gastroenterology 161(4):1118-1132, 2021). Neurologic involvement as extraintestinal manifestations are less common, reported at 3-19%, including neuropathies, demyelination, and cerebrovascular events (Morís in World J Gastroenterol. 20(5):1228-1237, 2014).

Probiotics And Human Milk Differentially Influence The Gut Microbiome And Nec Incidence In Preterm Pigs, Valeria Melendez Hebib, Diana H Taft, Barbara Stoll, Jinxin Liu, Lee Call, Gregory Guthrie, Nick Jensen, Amy B Hair, David A Mills, Douglas G Burrin

Faculty, Staff and Students Publications

Necrotizing enterocolitis (NEC) is the leading cause of death caused by gastrointestinal disease in preterm infants. Major risk factors include prematurity, formula feeding, and gut microbial colonization. Microbes have been linked to NEC, yet there is no evidence of causal species, and select probiotics have been shown to reduce NEC incidence in infants. In this study, we evaluated the effect of the probiotic Bifidobacterium longum subsp. infantis (BL. infantis), alone and in combination with a human milk oligosaccharide (HMO)—sialylactose (3′SL)—on the microbiome, and the incidence of NEC in preterm piglets fed an infant formula diet. We studied 50 …

Diagnostic Role Of Fractional Exhaled Nitric Oxide In Pediatric Eosinophilic Esophagitis, Relationship With Gastric And Duodenal Eosinophils., Panamdeep Kaur, Rachel Chevalier, Craig A. Friesen, Jamie Ryan, Ashley K. Sherman, Stephanie Page

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Eosinophilic esophagitis (EoE) is an eosinophilic-predominant inflammation of the esophagus diagnosed by upper endoscopy and biopsies. A non-invasive and cost-effective alternative for management of EoE is being researched. Previous studies assessing utility of fractional exhaled nitric oxide (FeNO) in EoE were low powered. None investigated the contribution of eosinophilic inflammation of the stomach and duodenum to FeNO.

AIM: To assess the utility of FeNO as a non-invasive biomarker of esophageal eosinophilic inflammation for monitoring disease activity.

METHODS: Patients aged 6-21 years undergoing scheduled upper endoscopy with biopsy for suspected EoE were recruited in our observational study. Patients on steroids …

Gastrointestinal Bleeding As Initial Manifestation Of Injection Drug Use-Associated Amyloidosis, Mohammed Rifat Shaik, Nishat Anjum Shaikh, Elvina Yunasan, Erika Wheeler, Robert T Chow

Journal of Community Hospital Internal Medicine Perspectives

Systemic amyloidosis has been reported in the context of injection drug use, usually related to ongoing chronic inflammation and persistent cutaneous infections. The kidneys are almost always the first organs affected in that setting. Involvement of the gastrointestinal tract is less common and rarely the initial site of presentation. We present a case of systemic amyloidosis that primarily manifested in the gastrointestinal tract, occurring in the setting of chronic injection drug use. The patient's hemoglobin level dropped progressively over time due to ongoing, slow gastrointestinal bleeding, prompting an endoscopic examination that ultimately confirmed the presence of gastrointestinal amyloidosis. As the …

Recurrent Psychosis In Non-Celiac Gluten Sensitivity, Scarlet Louis-Jean, Shire Chaudhry

Journal of Community Hospital Internal Medicine Perspectives

Neuropsychological manifestations following food exposures in patients with food sensitivities are increasingly being identified in the literature, as understanding of the gut-brain axis is further improved. Non-celiac gluten sensitivity (NCGS) has been shown to occur in individuals without serological or biopsied evidence of celiac disease (CD), who manifest psychotic or mood disorders that resolve following elimination of gluten. In this case history, we discuss a similar manifestation in a 31-year-old woman without serological evidence of CD, whose psychiatric symptoms improve with gluten elimination.

Colonic Stenosis In An Elderly Female, Tiffany R. Pittman, Kylie A. Parrish, Grace M. Perry, Oyindamola C. Orekoya, Shiv Dhiman, Savita Arya

Research Day

Introduction

Colonic stenosis is commonly caused by chronic inflammation and is a known side effect of inflammatory conditions, such as diverticulitis and irritable bowel syndrome. Diverticulosis is a common condition where parts of the colon wall become weakened, forming outpouches. These outpouchings may become inflamed, leading to diverticulitis. This chronic inflammation can cause scarring and fibrosis of the colon, resulting in colonic stenosis. Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, may also result in scarring and colonic stenosis. The incidence rate of patients developing colonic stenosis is 8-13.5% for Crohn's disease and 1-11% for ulcerative colitis. Patients …

Introduction: Bezoars are aggregates of undigested plant fibers, hair, or seeds that may impact in any portion of the GI tract. These bezoars if left can lead to significant complications, including perforation and peritonitis.

Methods: We report a case of a 4-year-old female patient who presented to the emergency department with constipation and severe lower abdominal pain following unsupervised consumption of a large unknown volume of sunflower seeds. Initial radiograph revealed an undigested bezoar of seeds in the sigmoid colon and rectum. The patient was managed with mineral oil enema and manual disimpaction under conscious sedation. Subsequent radiographs revealed a …

Evaluating The Impact Of Routine Enteral Iron Fortification On Gastrointestinal Dysbiosis In Premature Infants, Matthew Van Ormer

Theses & Dissertations

The gastrointestinal microbiome in preterm infants bears significant influence on optimal outcomes – dysbiosis is shown to substantially increase the risk of the life-threatening necrotizing enterocolitis, whereas optimal microbiome composition improves nutrient digestion and immune function. Iron is a vital nutrient especially during the perinatal window of rapid hemoglobin production, tissue growth, and foundational neurological development. However, excess colonic iron exhibits potent oxidation capacity and alters the competitive environment of microbes – potentially facilitating the proliferation of pathological bacterial strains in the gut. Of note, breastfed preterm infants routinely receive iron fortification starting at 14 days of life and are …

Rowan-Virtua Research Day

Introduction: Eating disorders (ED) such as bulimia and anorexia nervosa have detrimental implications on the health and wellbeing of children and young adults across the country. Cardiovascular implications are known to accompany these conditions, however there is a paucity of data looking specifically on the effects of NSTEMI on patients with these disorders. We sought to analyze this relationship further by examining these disorders within the national inpatient sample database to describe in-hospital trends and outcomes among those patients.

Methods: Data were extracted from the National Inpatient Sample (NIS) Database for the years 2019 and 2020. The NIS was searched …

When Constipation Becomes Lethal: Septic Shock Induced By Stercoral Colitis In A 77-Year-Old Female, Anna Delancy, Nicholas Tomasello, Joan Wiley, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Stercoral colitis is a form of colitis caused by fecal impaction distending the colon and causing fecaloma formation. Fecalomas lead to pressure necrosis of the colon and eventual perforation. The increased intraluminal pressure from the distention of the colon causes vascular compromise and ischemia. The most common locations of necrosis are in the sigmoid colon and rectum . When progressed to perforation, the mortality rate is as high as 60%. The most common cases of stercoral colitis occur in nursing home patients, mentally impaired patients, or those with chronic constipation. Here we describe an unusual case of stercoral colitis causing …

Sigmoid Perforation Extending Into The Abdominal Wall, Zamran Masih, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Sigmoid colon perforation and spread into the abdominal wall is a rare condition that can occur due to various causes such as diverticulitis, trauma, malignancy, or iatrogenic injury during surgery. Although rare, sigmoid colon perforation into the abdominal wall can result in significant morbidity and mortality if not promptly diagnosed and treated. Most common cause of diverticular disease leading to perforation is diverticulitis, accounting for 60% of all colonic perforations.

Loss Of Lgr5 Through Therapy-Induced Downregulation Or Gene Ablation Is Associated With Resistance And Enhanced Met-Stat3 Signaling In Colorectal Cancer Cells, Tressie A Posey, Joan Jacob, Ashlyn Parkhurst, Shraddha Subramanian, Liezl E Francisco, Zhengdong Liang, Kendra S Carmon

Faculty, Staff and Student Publications

Leucine-rich repeat-containing, G protein-coupled receptor 5 (LGR5) is highly expressed in colorectal cancer and cancer stem cells (CSCs) that play important roles in tumor initiation, progression, and metastasis. Loss of LGR5 has been shown to enhance therapy resistance. However, the molecular mechanisms that mediate this resistance remain elusive. In this study, we demonstrate conversion of LGR5+ colorectal cancer cells to an LGR5- state in response to chemotherapy, LGR5- targeted antibody-drug conjugates (ADCs), or LGR5 gene ablation led to activation of STAT3. Further investigation revealed increased STAT3 activation occurred as a result of increased mesenchymal epithelial transition (MET) factor receptor activity. …
