Amoxicillin-Clavulanate Related Liver Injury, Devin Vaishnani Md, Pratikkumar Vekaria Md, Ravish Patel Md, Megan White Md, Marvin Vaishnani Md Oct 2019

Amoxicillin-Clavulanate Related Liver Injury, Devin Vaishnani Md, Pratikkumar Vekaria Md, Ravish Patel Md, Megan White Md, Marvin Vaishnani Md

Gastroenterology

Introduction: Recognition of Drug-induced Liver Injury (DILI) may be challenging as it is often diagnosis of exclusion, unavailability of diagnostic test and variability in presentation. Many antibiotics can cause DILI but Amoxicillin-Clavulanate has rare adverse reaction causing mixed cholestatic-hepatocellular injury. Since amoxicillin alone does not induce liver injury, combination of amoxicillin and clavulanic acid could be responsible for this adverse reaction. It can be due to metabolic idiosyncrasy or hypersensitivity mechanism. Case Report: 64-year-old female with no pertinent PMH presented to ER with abdominal pain and jaundice. She had abdominal pain for 4-5 days. Abdominal pain was constant and located …


Evaluating The Role Of Fecal Microbiota Transplant In The Treatment Of Clostridium Difficile Infection, Anh Dao Le, Olivia Henton, Shane Bogusz, Brian Heilbronner, Jessica Hinson Oct 2019

Evaluating The Role Of Fecal Microbiota Transplant In The Treatment Of Clostridium Difficile Infection, Anh Dao Le, Olivia Henton, Shane Bogusz, Brian Heilbronner, Jessica Hinson

Pharmacy and Wellness Review

Fecal microbiota transplant (FMT) therapy is an increasingly prevalent treatment option for Clostridium difficile infection (CDI). Clostridium difficile infection is an aggressive and potentially fatal disease state, and antibiotic therapy often fails to resolve the disease state effectively. Clostridium difficile infection occurs most commonly subsequent to the use of antimicrobial agents that disrupt the natural bacterial flora of the gastrointestinal (GI) tract. Since disease state pathophysiology operates in this way, researchers have experimented with ways to restore GI flora to a natural state in which nonpathogenic bacteria can proliferate. Probiotic agents do not impose an acute enough response to recreate …


The Effect Of Cyp3a5 Polymorphism On Kidney Transplant Recipients Given Tacrolimus, Samia Alam, Sunitha Johns, Haval Norman, Brian Heilbronner, Yousif Rojeab Oct 2019

The Effect Of Cyp3a5 Polymorphism On Kidney Transplant Recipients Given Tacrolimus, Samia Alam, Sunitha Johns, Haval Norman, Brian Heilbronner, Yousif Rojeab

Pharmacy and Wellness Review

Tacrolimus, an immunosuppressant agent indicated for organ transplants, is commonly administered to reduce the risk of renal graft rejection in patients with chronic kidney disease (CKD) and end stage renal disease (ESRD). Due to its narrow therapeutic index and high inter-patient variability, studies have suggested that CYP3A5-based dosing provides specialized regimens which may significantly improve the chances of achieving therapeutic concentrations. According to the Clinical Pharmacogenetics Implementation Consortium (CPIC) recommendations, extensive (CYP3A5*1/*1) and intermediate metabolizers (CYP3A5*1/*3) require a higher initial dose while poor metabolizers (CYP3A5*3/*3) require a lower initial dose in order to achieve target tacrolimus concentrations. Studies concluded that …

What Is The Smartpill®?, Christina Ciccone, Pul Lee, Kimberly Loughlin, David Koh

Pharmacy and Wellness Review

The SmartPill® is a new, noninvasive technology to evaluate the gastrointestinal tract. It is a nondigestible capsule that migrates through the gastrointestinal tract to measure pH, pressure, and temperature. It was approved by the FDA in 2006 for the evaluation of colonic transit time in patients with chronic constipation and to evaluate gastric transit time in patients with suspected gastroparesis. Other currently used gastrointestinal monitoring systems have some disadvantages, and the SmartPill® is suggested as an alternative. The SmartPill® has also been used for research purposes in various studies and has the potential to be used in diagnosis and monitoring …

An Unusual Case Of Small Bowel Obstruction Secondary To Calcium Carbonate Use, Selsabeel Elyaman, Uma Gudur Md, Hady Khalifa, Alan Hamza, Andrew Seevaratnam Md

Gastroenterology

A Gastric Bezoar is defined as an accumulation of indigestible foreign material found in an individual’s GI tract. The incidence of gastric bezoar is 0.3% as reported by endoscopy studies. These formations usually consist of insoluble vegetable matter (phytobezoars), hair (trichobezoars), or medications (pharmacobezoar). In general, they can be asymptomatic for many years or cause nonspecific symptoms including abdominal pain, early satiety, and weight loss. However, in recent years, these have become increasingly problematic for the general population attributing to a variety of GI disturbances. We are reporting a case which revolves around a female patient with no history of …

Arachidin 3 Modulation Of Lipid Metabolism In Rotavirus Infections, Stormey Wisdom Jun 2019

Arachidin 3 Modulation Of Lipid Metabolism In Rotavirus Infections, Stormey Wisdom

Electronic Theses and Dissertations

Rotavirus (RV) can cause severe and deadly gastroenteritis in young children, infants, and immunocompromised individuals. Previous studies have shown that arachidin 3 (A3) inhibits RV replication, and that RV replication is dependent on the presence of lipids. This study investigated the alteration of lipid metabolism by A3 in RV infected HT29.f8 cells. A decrease in the RV regulation of lipid biosynthesis genes was observed with the addition of A3 using qRT-PCR. Also, immunofluorescent and histochemical staining for neutral fats, a major component of cellular lipid droplets, revealed an increased accumulation with both RV and RV+A3 when compared to no virus …

Shingles Vaccine: Identifying High Risk Groups In The Ibd Clinic Setting, Crystal Barajas

Doctor of Nursing Practice Final Manuscripts

Title: Shingles Vaccine: Identifying high risk groups in the IBD clinic setting

Background: The Inflammatory Bowel Disease (IBD) population is an immunocompromised patient population who is at risk for Herpes Zoster (HZ) due to their medication regimen, which further compromises their immune system. It can be difficult for patients to receive appropriate preventative health maintenance measures due to patients’ fears, primary care providers’ lack of knowledge, and gastroenterologists not addressing what may be considered primary care topics. Furthermore, evidence demonstrates that IBD patients have low vaccination rates despite insurance coverage.

Purpose of Project: (a) To increase awareness of the …

Gigantic Stomach: A Rare Manifestation Of Duchenne Muscular Dystrophy, Amaninder Dhaliwal, Sarvani Madiraju, Banreet S. Dhindsa, Getaw W. Hassen, Fedja A. Rochling May 2019

Gigantic Stomach: A Rare Manifestation Of Duchenne Muscular Dystrophy, Amaninder Dhaliwal, Sarvani Madiraju, Banreet S. Dhindsa, Getaw W. Hassen, Fedja A. Rochling

School of Medicine Faculty Research

Duchenne muscular dystrophy (DMD) is characterized by degeneration and atrophy of skeletal, cardiac, and smooth muscles after a latent period of apparently normal development and function. The gastrointestinal manifestations start in the second decade of life and are mainly due to atrophy of smooth muscle layers. Refractory gastroparesis and chronic constipation can lead to severe gastric and small bowel dilatation, which can be life threatening. Here, we present a case of a 21-year-old male with a gigantic stomach secondary to DMD resolved with conservative management and no surgical intervention.

Ethnic And Demographic Differences In Colectomy Rates And Timing For Ulcerative Colitis: 2007-2014, Daniel Bodek, Alana Persaud, Brian Blair, Ahlawat Sushil

Rowan-Virtua Research Day

Ulcerative Colitis (UC) is a chronic inflammatory disease of the bowel, with one third of patients requiring a colectomy for fulminant disease and tissue dysplasia. In 2007, infliximab was approved for induction and maintenance of remission in UC, with some evidence to suggest a potential reduction in colectomies. The aim of this study is to examine relative colectomy rates for UC among different ethnicities from 2007 to 2014 in order to evaluate for development of new trends or disparities.

Discrepancies in colectomy rates and timing are seen in our models which mirror closely findings in a prior study from 1999-2003 …

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin May 2019

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …

The aim of this study is to determine if children with hyperkinetic biliary dyskinesia have resolution of symptoms after laparoscopic cholecystectomy at our institution.

Conclusion: Cholecystectomy for hyperkinetic biliary dyskinesia may or may not improve symptoms. Further research should focus on pathophysiology of the disease in order to create an evidence-based definition of biliary dyskinesia in children to determine who will benefit from cholecystectomy.


Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner Apr 2019

Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In this introduction to Volume 6, Issue 2, the editor-in-chief of the Journal of Patient-Centered Research and Reviews offers additional comment to the clinical review of diabetic gastroparesis authored by Farmer and colleagues (p. 148), regarding the problem of undiagnosed disease. Increased awareness of this entity and appropriate questioning regarding symptoms of diabetic gastroparesis in the primary care setting may prevent the “suffering in silence” experienced by many patients with this complication.

Journal of Mind and Medical Sciences

Non-alcoholic steatohepatitis (NASH), also known as fatty liver disease (FLD), is a major public health problem. It is considered to be the hepatic manifestation of the metabolic syndrome. Chronic inflammation of the liver is an essential key in the progression from simple hepatic steatosis to steatohepatitis, the evolutionary stage of fatty liver disease. Moreover, the innate immune system plays a crucial role in the progression of hepatic inflammation. For this reason, it is of utmost importance to elucidate the connections between immune mechanisms, Toll-like receptor cytokine signalling, in order to find new effective treatments. Further studies are necessary to test …

Journal of Mind and Medical Sciences

Gut microbiota is an essential component in the pathogenesis of liver cirrhosis and its complications. There is a direct relationship between the gut and the liver called the gutliver axis through which bacteria can reach the liver through the portal venous blood. However, it remains unclear how bacteria leave the intestine and reach the fluid collection in the abdomen. A series of mechanisms have been postulated to be involved in the pathogenesis of spontaneous bacterial peritonitis (SBP) and other complications of liver cirrhosis, including bacterial translocation, bacterial overgrowth, altered intestinal permeability and dysfunctional immunity. The hepatic function may also be …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the life of …
