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.

Presentation, Diagnosis, And Acute Treatment Of Secondary Hemophagocytic Lymphohistiocytosis: A Case Report, Alexandra Bartholomew, Michael Connick, Catherine Loehr, Shane Sanne

School of Medicine Faculty Publications

Secondary hemophagocytic lymphohistiocytosis (HLH) is a rare, immunologically driven disorder with a high mortality rate. It is typically diagnosed on the basis of clinical and laboratory criteria. We present the case of a 53-year-old woman with multiple previous hospitalizations for fever of unknown origin and fatigue. Her workup ultimately led to a diagnosis of HLH. We discuss the presentation, diagnostic criteria, and clinical treatment of secondary HLH to guide workup and management for future patients affected by this rare disease.

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.

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 …

Atypical Presentation Of Cd4+ Small/Medium T-Cell Lymphoproliferative Disorder, Rafael Do Valle, Reem Ayoub, Marshall Hall, Henry Lim, Christian Scheufele, Garrett Furth, Michael Carletti, Stepehen E. Weis

North Texas Research Forum 2025

Introduction: Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (PCSM-LPD) is a rare cutaneous disorder that until 2016, was classified as a primary cutaneous lymphoma. PCSM-LPD histopathologically consists of a localized proliferation of small to medium-sized T lymphocytes. Clinically there is minimal to no systemic involvement. It typically presents as an asymptomatic, solitary red-purple nodule, papule, or plaque on the face. PCSM-LPD has an indolent course and an excellent prognosis. It is important to recognize PCSM-LPD as a distinct entity from primary cutaneous lymphoma to avoid treatments with side effects. Case Presentation: A 68-year-old female with a history of insulin-dependent type …

Tissue Kallikrein 1 Cleaves Complement Factor C3 And Activates The Alternative Complement Pathway, Sarah E. Sartain, Andrew Yee, Paula Jacobi

Research Data

Hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA), characterized by microvascular endothelial damage and severe renal injury, negatively affects HSCT survivorship with high mortality and long-term renal morbidity. After HSCT, innate immunity and inflammation are often dysregulated. The alternative complement pathway (AP) of the innate immune system is overactivated in HSCT-TMA, but the mechanisms of its initiation are poorly described. Complement component C3 of the AP can be cleaved by proteases outside of the AP. Because mRNA expression of tissue kallikrein 1 (KLK1), an inflammatory serine protease that produces kinins, has been found to be markedly elevated in the renal endothelium …

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 …

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 …

Novel Spirocyclic Dimer (Spid3) Displays Potent Preclinical Effects In Hematological Malignancies, Alexandria Eiken

Theses & Dissertations

Chronic lymphocytic leukemia (CLL) is a heterogeneous disease characterized by the accumulation of mature CD5⁺ B-cells in the peripheral blood, bone marrow, and secondary lymphoid tissues (e.g., spleen and lymph nodes).Despite the efficacy of front-line therapies, CLL is still an incurable disease, highlighting the need for development of novel therapeutics and further study of resistance mechanisms. Within the lymph node CLL tumor microenvironment (TME), there is an upregulation of gene signatures associated with B-cell receptor (BCR) and downstream nuclear factor kappa B (NF-κB) signaling compared to CLL cells found within the blood or bone marrow niches. Additionally, BCR signaling …

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 …

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.

A Rare Case Of Cold Agglutination Syndrome Secondary To Mycoplasma Pneumoniae, Dr.Disha Shahri, Dr. Srinath K. M, Dr. Basava Chethan, Dr. Savitha Vijayakumar, Dr. Meghna B.S.

Digital Journal of Clinical Medicine

Mycoplasma pneumoniae (M. pneumoniae) is one of the foremost causes of community acquired pneumonia. Most of the cases are, however mild. Although, complications may seldom occur. One such known complication of M. pneumoniae infection is cold agglutinin hemolysis, which is usually benign and transient. This hemolysis is due to formation of cold agglutinins during the course of infection. Cold Agglutination Syndrome (CAS) is a type of acquired Autoimmune Hemolytic Anaemia (AIHA), which exists due to an underlying disorder, like a viral illness or lymohoid malignancy. It is generally self-remitting, in contrast to Cold Agglutination Disease (CAD), which is a chronic …

The Effect Of Carfilzomib And Bortezomib Based Regimes On Cardiotoxicity In Multiple Myeloma Patients At Cooper University Hospital, Ami Patel, Tulin Budak-Alpdogan, Stalam Tapati

Rowan-Virtua Research Day

Introduction

• Multiple myeloma (MM) is a cancer of plasma cells, which is a white blood cell that normally produces antibodies
• Treatment in patients younger than 65 years old is typically high dose chemotherapy, usually with bortezomib based regimens or lenalidomide dexamethasone, followed by a stem cell transplant
• For patients with relapsed myeloma, carfilzomib is usually the treatment of choice
• Carfilzomib is a highly selective, irreversible proteasome inhibitor that binds to the 20 S proteasome. Several studies have illustrated that carfilzomib has been associated with cardiovascular adverse events (CVAE).
• Current literature on the role and effect of bortezomib on cardiotoxicity is …

Heterogeneous Nuclear Ribonucleoprotein K (Hnrnp K) Overexpression And Its Interaction With Runx1 Rna In Acute Myeloid Leukemia, Marisa Aitken

Dissertations and Theses (Open Access)

Acute myeloid leukemia (AML) is an often devastating hematologic malignancy with 5-year overall survival lingering near 20%. Acquiring a deeper understanding of molecular underpinnings of leukemogenesis will provide a basis for developing more effective therapeutic strategies for patients with AML.

Here, we identified overexpression of hnRNP K as a recurrent abnormality in a subset (~20%) of AML patients. High levels of this RNA-binding protein associated with inferior clinical outcomes in de novo AML. Thus, to evaluate its putative oncogenic capacity in myeloid disease, we overexpressed hnRNP K in murine hematopoietic stem and progenitor cells isolated from fetal liver cells (FLCs). …
