Kshv Vil6 Inhibits Functional B Cell Maturation During De Novo Infection, Wajd Zakir, Jessica M. Osborn, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Despite causative links to lymphoproliferative disorders, little is known about early events governing KSHV infection in B lymphocytes. IL-6 signaling plays a critical role in KSHV-mediated disease, with human IL-6 (hIL6) levels correlating with viral load and disease progression. This dynamic is even more complex due to the coexistence of hIL6 and KSHV-encoded viral IL-6 (vIL6) in these diseases. We hypothesize that hIL6 and vIL6 play critical, separable and collective roles in the early stages of KSHV infection in B cells. In this study, we use our ex vivo model of KSHV infection in human tonsil lymphocytes to investigate the …

Parvovirus B19 Infection In Kidney Transplant Recipients, Hatem Najar, Kiran Goli, Maria P. Martinez Cantarin

Division of Nephrology Faculty Papers

On August 14, 2024, the Centers for Disease Control issued a Health Alert Network (HAN) health advisory due to a surge in Parvovirus B19 (B19V) infections in the United States. Our report presents two cases of suspected donor-derived Parvovirus B19 infection in kidney transplant patients. Both cases had refractory anemia requiring treatment with intravenous immunoglobulin. These cases highlight the importance of awareness and monitoring of B19V infection in the context of recent epidemiologic trends to improve clinical outcomes in kidney transplant recipients.

Atypical Dengue Fever With Severe Hematological Manifestations: A Case From The Rio Grande Valley, Elias Arellano Villanueva, Alhasan Asaad, Jose Campo Maldonado

Research Symposium

Background: Dengue fever, a mosquito-borne viral illness, is endemic in tropical regions, including border regions like the Rio Grande Valley while often self-limited, severe presentations such as dengue hemorrhagic fever and dengue shock syndrome highlight its challenges and complexities. This report describes an atypical dengue case with severe hematological manifestations, underscoring the diagnostic challenges and the importance of early recognition, multidisciplinary evaluation, and evidence-based management.

Case Presentation: A 22-year-old Hispanic female with no significant past medical history presented to the ED with hematemesis and fever following her travel to Monterrey, Mexico. Initial symptoms included high fever (107.6°F), chills, diarrhea, vomiting, …

Therapeutic Effects Of Bet Protein Inhibition In B-Cell Malignancies And Beyond, Audrey L. Smith

Theses & Dissertations

Chronic lymphocytic leukemia (CLL) develops through a combination of intrinsic genetic defects, constitutively active survival/proliferation signaling pathways, and complex microenvironment interactions. Redundant tumor microenvironment (TME) immuno-suppressive mechanisms and epigenetic maintenance of terminal T-cell dysfunction also greatly hinder anti-tumor T-cell responses in CLL. Small-molecule agents targeting the B-cell receptor (BCR) pathway and anti-apoptotic proteins alone or in combination with chemo-immunotherapy have revolutionized the management of CLL, yet there is still a significant need for novel therapeutic strategies to yield durable tumor elimination. Bromodomain and extra-terminal domain (BET) proteins are epigenetic readers that bind to acetyl-lysine residues on histones to regulate gene …

Chilling Complications: A Case Of Covid-Associated Cold Autoimmune Hemolytic Anemia (Aiha), Julian Coz, Kishan B. Patel

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 …

Covid-19 Masking An Atypical Presentation Of Hairy Cell Leukemia, Kahmalia-Kalee Sada

North Texas GME Research Forum 2023

Hairy cell leukemia is a rare lymphoid neoplasm of small mature B cell lymphoid cells. Hairy cell leukemia only accounts for about 1 to 2 percent of adult leukemia cases. Early diagnosis of Hairy cell Leukemia is important, it is proven that without treatment the median survival of this cancer is four years. After numerous studies the age-adjusted risk of death with proper diagnosis and treatment has decreased by 85%. The greatest outcomes are seen in individuals who are younger with earlier diagnosis. Hairy Cell Leukemia is a rare leukemia seen with the classic triad of splenomegaly, pancytopenia, and “hairy” …

Pancytopenia, Enterovirus Infection, And Pcr Testing, Stephen Mock, Salome Herzstein, Andrea Horbey

East Florida Division GME Research Day 2023

Introduction: This is a case of a patient presenting with fever, rash, and vomiting. Upon further studies, patient was found to have pancytopenia which started an extensive hospital work up.

Case Description: A previously healthy 9- year-old female presented to the emergency department with 3 days of tactile fever, 2 days of rash, and 1 day of nonbilious nonbloody emesis. The rash initially appeared on the trunk and by the day of admission, had begun to spread peripherally to the extremities. The rash on the abdomen was described as mild, generalized, blanchable and maculopapular. The rash on the extremities was …

Intermediate Anticoagulation Dosing In Covid-19 Icu Patients: Evaluation Comparing Ventilated Vs Non-Ventilated Populations, Christopher Michael D'Amico

Applied Research Projects

Surges of COVID-19 have been seen to place large numbers of patients into the ICU. Establishing standards of care is critical not only for patient care, but to also implement a baseline of therapy to build upon with future research. COVID-19 produces a hypercoagulable state resulting in higher occurrences of clotting such as deep vein thrombosis (DVT), and pulmonary embolism (PE). Anticoagulation medications thin the blood to combat this aspect of the disease from occurring but does so at the risk of increasing bleeding potential. The purpose of this study is to evaluate the risk/benefit of anticoagulation usage between ventilated …

Extrafollicular Activities: Perspectives On Hiv Infection, Germinal Centerindependent Maturation Pathways, And Kshv-Mediated Lymphoproliferation, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Early events in the pathogenesis of KSHV-associated lymphoproliferations in the context of HIV disease remain poorly understood. Recent research indicates that latent HIV infection causes persistent immune dysfunction in B cell follicles. Simultaneously, lack of T cell immune surveillance in the lymph nodes dysregulates the biology of EBV. In sum, these defects bias B lymphocyte maturation away from traditional T cell-dependent germinal center-mediated pathways and towards extrafollicular pathways. Recent advances in B lymphocyte immunology suggest that extrafollicular maturation pathways for antibody secreting cells are more flexible and robust than previously believed. These responses are now understood to be both durable …

Knowledge And Beliefs Of Adolescents Regarding Sexually Transmitted Infections And Hiv/Aids In A Rural District In Pakistan, Hafsa Raheel, Franklin White, Muhammad Masood Kadir, Zafar Fatmi

Community Health Sciences

Objective:

To assess the knowledge and beliefs of adolescents (15-19 years girls and boys) regarding sexually transmitted infections (STIs) and HIV/AIDS.

Methods:

A community based cross-sectional survey was conducted in October 2002 in a rural district (Mirpurkhas) of Sindh province, Pakistan.

Results:

A total of 428 adolescent girls and boys were interviewed. Only 44% correctly named at least one STI, while 55% knew at least two modes of transmission for HIV/AIDS. Adolescents with education greater than or equal to secondary level, those who were able to read the newspaper, possessed electricity in their homes and were allowed to meet their …
