What Is The Role Of The Gut Microbiome In Modulating Immune Tolerance And The Development Of Allergic Disease In Infants?, Priyal Gajera

Rowan-Virtua Research Day

Introduction: The infant gut microbiome plays a critical role in immune system development during the early-life “window of immune education.”¹ Microbial colonization influences immune tolerance through mechanisms such as regulatory T-cell (Treg) induction, short-chain fatty acid (SCFA) production, and mucosal immune regulation. Disruptions in this process (dysbiosis) are associated with increased risk of allergic diseases, including food allergy, atopic dermatitis, and asthma. Environmental and maternal factors such as delivery mode, antibiotic exposure, and feeding practices significantly impact microbial composition and immune outcomes.²

Methods: A literature review was conducted using PubMed with search terms related to the gut microbiome, …

Cold Agglutinin Disease A Case On Diagnostic Pitfalls And Decision-Making Strategy, Portia Shaheed, Shefali Waghray Do, Te Du Md, Phd

Rowan-Virtua Research Day

Cold agglutinin disease is a rare subtype of autoimmune hemolytic anemia (AIHA) characterized by complement-mediated hemolysis triggered by cold temperatures. Because of its rarity and variable presentation, cold agglutinin disease is frequently underrecognized, often leading to extensive and sometimes unnecessary diagnostic evaluations. By recognizing cold agglutinin disease as a differential diagnosis in patients with recurrent admissions for hemolysis, clinicians can avoid unnecessary workups, consults, and distress for their patients.

Efficacy Of Omalizumab And Exposure Immunotherapy In Reducing Allergic Immunological Response, Joshua James Novello, Michelle Lau, Josephine L. Miner, Mudassir A. Rahmani, Kimran Sandhu, Taha Umar

Rowan-Virtua Research Day

Background: Food allergy negatively impacts numerous children in the United States. Oral immunotherapy (OIT) and biologic therapy (omalizumab) are emerging promising strategies for desensitization. This literature review aims to compare the effectiveness of omalizumab and oral immunotherapy in pediatric populations.

Hypothesis: If the use of omalizumab therapy is used to treat children with food allergies compared to OIT, then there would be higher desensitization, lower post-treatment IgE levels, higher IgG4 levels, and decreased chance of a positive skin prick test.

Methods: PubMed, Embase, and The Lancet databases were searched using PRISMA guidelines to locate peer-reviewed studies evaluating …

Delayed Diagnosis Of Systemic Lupus Erythematosus Presenting As Autoimmune Hemolytic Anemia: A Case For Heightened Clinical Suspicion, Diana Acosta Pozo, Luis Álvarez Pérez

Research Colloquium

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem involvement, including hematologic manifestations. Autoimmune Hemolytic Anemia (AIHA), though an established feature, is relatively uncommon and may occur early or in isolation. When AIHA presents without overt systemic symptoms, the underlying autoimmune etiology may be overlooked, resulting in delays in diagnosis and treatment. Prompt recognition is essential to prevent unnecessary interventions and prolonged morbidity.

Case Presentation: A 39-year-old woman residing in Texas presented to the Rheumatology office with persistent synovitis and severe transfusion-dependent anemia, requiring red blood cell transfusions every 48 hours for over three months. She …

The Impact Of Covid 19 Infection On Graves' Disease, Shadi Jafari-Esfahani, Semenawit B. Burka, Edwardo D. Luna

Research Colloquium

Background: Although there are not many studies regarding the effects of Covid-19 infection on Graves’ disease, few case reports demonstrate the association between the two. The SARS-CoV-2 uses the angiotensin II converting enzyme to gain entry into cells. This results in hyperactive immune response involving Th1 and Th17 lymphocytes which activates proinflammatory cytokines; IL-6 and TNF-alpha. Research shows elevation of IL-6 in patients with Graves’ disease.

Case report: A 22 years old man with no past medical history presented to the Emergency Room for the complaint of generalized weakness and dyspnea of one day. He had associated dry cough, palpitations, …

Research Days

We created a model to test the immunosuppressive capacity of Helios+FOXP3+ eTregs compared to nTregs against islet-specific autoreactive T cells. We also showed that nTregs decrease the response of these cytotoxic T cells when co-cultured with BetaLox5 cells.

Autoimmune Encephalitis Presenting As Pseudodementia (Case Report), Renita Ng, Christie Richardson

Rowan-Virtua Research Day

Patients with autoimmune encephalitis frequently present with psychiatric symptoms including psychosis, behavioral changes, and affective disorders. Because of this, misdiagnosis of a primary psychiatric disorder in a case of autoimmune encephalitis is not uncommon. We present a case of autoimmune encephalitis in a 72 year old who was initially thought to have psuedodementia or catatonia due to variable collateral who later on LP was found to have markers and responded to steroid treatment. This case highlights the importance of maintaining a broad differential with patients who present with psychiatric alterations and to consider other causes of behavioral change.

Case Report: Recurrent Miller Fisher Syndrome, Devin Hoover, Andrew Vasta, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report the case of a 47-year-old male who presented with numbness and difficulty speaking and was diagnosed with Miller Fisher Syndrome, a variant Guillain-Barré Syndrome. The differential diagnosis for numbness and speech difficulty is broad and includes brain stem stroke, Wernicke encephalopathy, botulism, myasthenia gravis, among others. Although Miller Fisher Syndrome is rare, certain factors such as the of tumor necrosis factor-alpha antagonists may predispose a patient to the disease and its recurrence. As discovery of new tumor necrosis factor-alpha antagonists continues it will likely result in more presentations of Guillain-Barré Syndrome and its variants to the emergency department.

Miller Fisher Variant Of Guillain- Barré Syndrome, Peter Killian, Kishan B. Patel

Rowan-Virtua Research Day

We present a case of a man in his 50s who was evaluated in the emergency department for right facial droop, myalgias, and right lower extremity weakness. The patient required multiple interdisciplinary specialists for treatment and diagnosis of Guillain-Barré Syndrome (GBS). The differential for weakness and facial droop is primarily aimed at ruling out an irreversible neurological cause while investigating a potential infectious etiology. Multiple variants of GBS exist and clinical presentations can vary, including the Miller Fisher Variant. This variant features a unique presentation, affecting the corticobulbar tract, evident with the ptosis commonly seen following a gastrointestinal infection.

A Rare Case Of Diffuse Alveolar Hemorrhage In The Setting Of Iga Nephropathy, Vasculitis And Atypical Hemolytic Uremic Syndrome In A Previously Healthy Young Adult, Karl Schlicht, Nancy Kaura

Rowan-Virtua Research Day

IgA Nephropathy, also known as Berger disease, can precipitate acute renal failure in patients. IgA Nephropathy (IgAN) is deposition of protein from IgA into the renal tissue with subsequent renal dysfunction. IgA vasculitis (IgAV) is another condition where similarly the protein of IgA is deposited into the vessels. There are some cases of co-existing atypical hemolytic uremic syndrome (aHUS) with IgAN. However, rare combinations seen with all three IgAN, IgAV, and aHUS without any pre-existing conditions nor medical history. Patients that develop any one of these conditions are looking at life long changes with hemodialysis (HD) and organ transplants being …

Progressive Multifocal Leukoencephalopathy (Pml) Induced By Jc Virus: A Case Report And Review Of Clinical Implications, Hugo Zamarron, Roberto Cruz

Research Symposium

Background: Progressive multifocal leukoencephalopathy (PML) is a rare but serious demyelinating disease of the central nervous system, caused by the John Cunningham (JC) virus. While the JC virus is common in the general population, it remains dormant in healthy individuals but can reactivate in immunocompromised patients, particularly those with HIV/AIDS or undergoing immunosuppressive treatments for organ transplants or autoimmune conditions. The virus attacks oligodendrocytes, leading to demyelination and significant neurological deficits. Immunosuppressive therapies such as natalizumab, rituximab, and mycophenolate increase the risk of PML. Diagnosing PML is challenging as its symptoms—focal neurological deficits, sensory-motor issues, and visual disturbances—overlap with conditions …

Long-Term Safety And Comparative Efficacy Of Il-17 Inhibitors In Treating Ankylosing Spondylitis, Alyssa L. Sepulveda, Yolanda V. Gutierrez, Ronald A. Shaju

Research Symposium

Background:
Ankylosing Spondylitis (AS) is a chronic inflammatory disease affecting the axial skeleton, characterized by spinal stiffness, sacroiliitis, and potential vertebral fusion. While nonsteroidal anti-inflammatory drugs (NSAIDs) and tumor necrosis factor (TNF) inhibitors are first-line treatments, IL-17 inhibitors, such as secukinumab and ixekizumab, are used in patients with inadequate response or contraindications to TNF inhibitors. These targeted therapies address IL-17’s role in driving inflammation and structural damage in AS.

Methods:
A systematic review was conducted using PubMed, Science Direct, and Cochrane to identify studies published between 2000 and 2025. Keywords included “Ankylosing spondylitis” and “IL-17 inhibitors” and “efficacy.” Inclusion criteria …

A Galleria Mellonella Study: Protective Effects Of Sulforaphane On Immune Function In Binge Alcohol Exposure, Robert Kento Darby, Braydon Black, Vincent Tran, Dallen James, Scott Quimby

Annual Research Symposium

Alcohol is associated with increased mortality and morbidity. Pulmonary infections with opportunistic pathogens can occur in healthy humans; however, hazardous alcohol exposure like binge alcohol intoxication (≥ 0.08% BAC) is a major risk factor. We’ve previously investigated the efficacy of Sulforaphane (SFN) prophylaxis in protecting human and murine alveolar macrophage function against opportunistic infections when exposed to binge alcohol conditions in vitro. However, an in vivo model investigating SFN and hazardous alcohol exposure in the context of infection is not well understood. The aim of this study is to 1) establish a G. mellonella larvae model by determining the LD50 …

Nosebleed No More: Recognizing And Diagnosing Factor Viii Inhibitor, Salam Harb, Leidy Huie Martinez Md, Jose Alvarado Md, Ajit Koli Do, Hazem Nasef Ms4

HCA-NSU MD Research Day

Acquired hemophilia is a condition characterized by the unexpected onset of severe bleeding due to an issue with coagulation factors. Typically, this disorder results from the production of autoantibodies against the Factor VIII coagulation factor. Although acquired hemophilia is an extremely rare condition, with an annual incidence of just 1.5 cases per million, it is crucial to recognize and understand it. This is because diagnosing this disorder is intricate, and if left undiagnosed and untreated, it can lead to high levels of morbidity and mortality. This case stands out as the condition typically targets older adults, with around 80% of …

Using A Rabbit Model To Understand The Impact Of Oral Versus Intravenous Transmission Of Epstein-Barr Virus, Meera Mohammed Al Ameri

Thesis/ Dissertation Defenses

The isolation of Epstein-Barr Virus (EBV) in 1964 from a case of Burkitt lymphoma prompted a surge in research on the biology of this oncogenic virus and its role in the pathogenesis of associated malignancies. Over half a century later, a number of pertinent questions on the dynamics of EBV and the cellular targets of primary infection remain poorly defined. One major obstacle in EBV research has been the lack of a suitable small animal model. EBV is a highly human tropic virus. We have recently established a novel rabbit model of EBV infection that appears to mimic natural infection …

Prognostic Utility Of The Lactate/Pyruvate Ratio For Mortality In Patients With Sepsis: An Observational Study, Edgar G. Dorsey-Trevino, Olga G. Cantu-Rodriguez, Jose A. Hawing-Zarate, Grecia A. Gonzalez-Cantu, David Gomez-Almaguer, Cesar H. Gutierrez-Aguirre

Research Colloquium

Introduction: Measurement of serum lactate remains pivotal in sepsis evaluation as it is closely related to tissue hypoxia and mortality.^{1, 2} Serum lactate, however, can be elevated due to a myriad of reasons beyond hypoperfusion.³ A proposed alternative to control for serum lactate’s inherent variability is to measure pyruvate concomitantly to calculate the lactate/pyruvate (L/P) ratio.^{4, 5} As pyruvate transforms into lactate in anaerobic conditions, its value decreases in serum, increasing the L/P ratio, hence indicating an actual tissue-perfusion mismatch.⁶ Despite its clinical utility, there is a paucity of evidence evaluating the role of the L/P …

A Presentation Of Myelin Oligodendrocyte Glycoprotein Antibody Associated Disease (Mogad) As Optic Neuritis, Kirhyn A. Stein, Laura Garcia, Sobia Memon, Hernan Guanajuato, Johanna Mora

Research Colloquium

Background: Myelin Oligodendrocyte Glycoprotein Antibody Associated Disease (MOGAD) is a relatively new and rare autoimmune disease that causes demyelination of the central nervous system. The pathogenicity of this disease is characterized by an immune reaction against myelin oligodendrocyte glycoprotein: a component of the myelin sheath that is also expressed on the surface of oligodendrocytes. The purpose of this glycoprotein is thought to be for construction and maintenance of myelin and cell to cell communication. The destruction of oligodendrocytes and myelin in the central nervous system affects the brain, spinal cord, and optic nerves, and can cause symptoms such as acute …

Case Report: Dysphagia In Inclusion Body Myositis Leading To Respiratory And Gastrointestinal Complications, Veroneka Mikhail, James A. Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Inclusion Body Myositis (IBM) stands as a rare and complex neuromuscular disorder (NMD) characterized by progressive muscle weakness and atrophy. Among its cardinal symptoms are dysphagia and respiratory distress, which are the most common cause of death in this disease. While the differential diagnosis of respiratory distress is vast and includes aspiration, pneumonia, acute coronary syndrome, emphysema, and congestive heart failure, a clinician should recognize that respiratory distress can also be secondary to dysphagia in NMDs like IBM and can quickly become life threating. Here we present the case of a 68-year-old female with a history of IBM who presented …

A Systematic Review On Belimumab’S Effectiveness, Improved Health Outcomes And Quality Of Life In Patients With Lupus Syndromes, Emily Meale, Alexandra Fontaine

Rowan-Virtua Research Day

Autoimmune diseases are prevalent disorders that many individuals within the United States suffer from. Systemic lupus erythematosus (SLE) is a common autoimmune disease that has a high incidence in women of child-bearing age. Management for lupus depends on the anatomical location SLE manifests, the severity of disease, and the tolerance that one has for certain adverse effects. Glucocorticoids are commonly used to manage lupus. Currently, long term glucocorticoid usage is associated with devastating adverse effects, so current treatment options aim to mitigate corticosteroids use to improve quality of life while maintaining favorable health outcomes. New management for SLE include biologics …

A Novel Approach To Hiv Testing: Group Harm Reduction And Testing For High Risk Women In Nj, Gabrianna A. Andrews

Rowan-Virtua Research Day

Outreach programs have been implemented aimed at providing healthcare to minority populations and those considered high-risk for acquiring HIV. Variables such as these cause hesitance in community members, preventing HIV screenings and adherence to follow-ups. This study provides and evaluates a new approach: group HIV testing. Data was collected from 6/2/2023 to 4/19/2024 by surveying participants at the end of the interaction. 87.5% of participants rated their care at the mobile clinic as ‘Excellent’, 8% as ‘Very Good’, and 4.5% as ‘Good’. 95.6% of participants ranked Group Harm Reduction Counseling as ‘Definitely’ helpful. 84.4% of participants did not find that …

“Lupus, Marijuana, And Takotsubo: A Perfect Storm”: An Unusual Presentation Of Takotsubo Cardiomyopathy, Matthew Orap, Parth Patel, Haitham Dib

Rowan-Virtua Research Day

Takotsubo cardiomyopathy is a type of myocardial injury that is marked with left ventricular contraction dysfunction. Various regions of the left ventricular wall may exhibit hypokinetic or hypercontractile activity. There is no exact mechanism elucidated for Takotsubo cardiomyopathy, but it is often associated with a triggering stressful event that leads to a catecholamine surge. We describe a 38-year-old female who presented with typical Takotsubo cardiomyopathy, likely in the setting of worsening systemic lupus erythematosus (SLE) exacerbations and excessive cannabis use. The patient described her pain as a tight burning sensation that started on her right side and traveled to the …

Rowan-Virtua Research Day

Cold Agglutinin disease (CAD) also known as Cold Autoimmune Hemolytic Anemia (AIHA) is a form of autoimmune hemolytic anemia wherein cold agglutinins (IgM autoantibodies against red blood cell (RBC) antigens) bind during cold temperatures causing clinical symptoms related to RBC agglutination resulting to hemolytic anemia. Clinicians should recognize that Cold Agglutinin disease can be secondary to an underlying pathology such as COVID-19. Here we describe an unusual case of Cold Agglutinin Autoimmune Hemolytic Anemia which was diagnosed in the Emergency Department with the presence of COVID-19 and with a hospital course complicated by acute deep vein thrombosis (DVT) and bilateral …

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

A True Bloody Emergency: An Unusual Case Of Thrombotic Thrombocytopenic Purpura, Joshua M. Ninan

Research Symposium

Background: Thrombotic thrombocytopenic purpura (TTP) is a primary thrombotic microangiopathy that is classically characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA). Although rare with an annual incidence of 3.7 cases per one million adults, it is considered a true hematological emergency due to its fatality rate of almost 100% if appropriate treatment is not initiated immediately. This makes it vitally important to identify and treat patients with TTP, a task that becomes unusually challenging in the absence of the disorder’s other characteristically diagnostic clinical features such as mucosal bleeding, fever, or presence of schistocytes.

Case Presentation: A 30-year-old gentleman with …

Avaren-Fc, A Novel Immunotherapeutic, Recruits Nk Cells In B16f10 Melanoma Tumor Tissue, Sreevatsa Vemuri, Katarina Mayer, Nobuyuki Matoba

Posters-at-the-Capitol

Melanoma is the fifth most common cancer in the US, with limited effective immunotherapeutic options available for patients. Avaren-Fc (AvFc) is a novel experimental immunotherapeutic agent with a unique “lectibody” property. It is capable of targeting cancer cells through the selective recognition of high mannose glycans, which are aberrantly overrepresented on the surface of malignant cells. AvFc can interact with circulating effector immune cells equipped with Fc receptors, such as natural killer (NK) cells to induce antibody-dependent cell-mediated cytotoxicity (ADCC) and kill cancer cells. Previous work has shown that AvFc effectively induces ADCC activity against B16F10 cancer cells in vitro …

Examining The Efficacy Of Treatments For Complex Regional Pain Syndrome, Michael Podcasy

Capstone Showcase

Complex Regional Pain Syndrome (CRPS) is a disease that affects the sensory, motor, sudomotor, vasomotor and trophic systems of patients. The pathophysiology is currently unknown and the diagnostic criteria that is used, the Budapest criteria, has its own shortcomings. This had led to hurdles in the research of the disease and well as a lack of high-quality studies on the efficacy of the many treatments currently being used to treat CRPS today. This poster explores those concepts.
