Multiple Intracardiac Thrombi In A Patient With Ischemic Cardiomyopathy, Jian Garcia Cruz, Julio Perez Rodriguez

Research Colloquium

Introduction: Ischemic cardiomyopathy is defined by the American Heart Association (AHA) as cardiomyopathy caused by ischemic heart disease. The most common complication of ischemic cardiomyopathy is systolic congestive heart failure. Heart failure patients are in a hypercoagulable state that predisposes them to develop intracardiac thrombus. The incidence of LV thrombus in patients with dilated cardiomyopathy and sinus rhythm is 13% with the clot in the left atrial appendage in 68% of these cases. The thrombus formation results from impaired blood flow within the 4 chambers of the heart and can present as a life-threatening complication of end stage heart failure. …

Cardiac Tamponade Secondary To Purulent Pericarditis With Mrsa, Jian Garcia Cruz, Julio Perez Rodriguez

Research Colloquium

Introduction: Methicillin resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that causes severe morbidity and mortality worldwide. MRSA pericarditis is a rare life-threatening condition that can cause purulent pericarditis with only 7 cases having been reported so far. Several reasons why a patient may develop MRSA pericarditis are healthcare-associated infection, weakened immune system, invasive procedures and spread from other infections. Although not typically associated with tamponade, if MRSA were to cause an infection in the pericardial space, it could potentially lead to inflammation and fluid accumulation, resulting in tamponade. We present a case of a woman that developed tamponade secondary …

Unveiling The Neurological Aftermath: Pres After Cardiac Arrest, Oyinlola O. Fasehun, Jessica Daza, Sriharsha Koneru, Victor Tran, Eunbee Cho, Fatimah Bello

Research Colloquium

Background: Posterior Reversible Encephalopathy Syndrome (PRES), also known as ‘Reversible Posterior Leukoencephalopathy Syndrome (RPLS)’, is a clinical radiographic syndrome originally described by Hinchey et al in 1996. PRES has been significantly underdiagnosed due to difficulty in confirmation. As such, there is currently no epidemiological data regarding its incidence, but it has been diagnosed in all age groups with a preponderance in females. A variety of medical conditions have been implicated as causes of PRES, including severe hypertension, immunosuppressive therapy, sepsis, renal diseases and autoimmune disorders. The mechanism of PRES is thought to be related to disordered cerebral autoregulation and endothelial …

Pernicious Anemia Presenting With Pancytopenia And Hemolysis: A Case Report From South Texas, Yareli Durazo, Victor Tran, Sriharsha Koneru, Andres Suarez Parraga

Research Colloquium

Introduction: Pancytopenia is a commonly encountered hematologic entity with varying clinical presentations. It results from various disease processes ranging from simple to life-threatening. The most common cause of pancytopenia is megaloblastic anemia, and the most common causes of megaloblastic anemia are deficiencies of vitamin B9 or B12. Thus, folate and B12 deficiency should be high in the differential diagnosis when patients present with pancytopenia. Hemolytic anemia, anemia due to the shortened survival of circulating erythrocytes, often represents a more difficult diagnostic challenge for the clinician. While recognition of ongoing hemolysis is usually rapid and relatively simple, establishing the cause can …

Gastrointestinal Bleed In The Context Of Hemophilia A In An Incarcerated Patient In The Rio Grande Valley, Cameron B. Caldwell, Hector Trejo, Andres Suarez-Parraga

Research Colloquium

Background: Hemophilia A, the most common X-linked hereditary hemostasis disorder, has an incidence of approximately 1 in 5600 male live births worldwide. It results from a deficiency of clotting factor VIII, crucial for fibrin generation in the coagulation cascade, leading to inadequate fibrin generation and defective secondary hemostasis. Hemophilia can cause life-threatening bleeding, characterized as severe (< 1% factor VIII activity), moderate (2-5%), or mild (6-40%). Social determinants of health pose significant challenges in managing hemophilia in underserved populations. This case presents gastrointestinal bleeding in a mild hemophilia A patient in the Rio Grande Valley.

Mesenchymal Stromal Cells Protect Combined Oncolytic And Helper-Dependent Adenoviruses From Humoral Immunity, Ada Irmak Özcan, Arianexys Aquino Lόpez, Alexandra N Wolff, Audrey Ma, Amanda Rosewell Shaw, Masataka Suzuki, Malcolm K Brenner, Mary K Mckenna

Faculty, Staff and Students Publications

Systemic delivery of oncolytic and immunomodulatory adenoviruses may be required for optimal effects on human malignancies. Mesenchymal stromal cells (MSCs) can serve as delivery systems for cancer therapeutics due to their ability to transport and shield these agents while homing to tumors. We now use MSCs to deliver a clinically validated binary oncolytic and helper-dependent adenovirus combination (CAdVEC) to tumor cells. We show successful oncolysis and helper-dependent virus function in tumor cells even in the presence of plasma from adenovirus-seropositive donors. In both two- and three-dimensional cultures, CAdVEC function is eliminated even at high dilutions of seropositive plasma but is …

School of Medicine Faculty Publications

Background: Upregulation of IL-6 has been associated with worse prognosis in COVID-19 patients. Impact on IL-6 signalling has mostly been limited to clinical outcomes in IL-6 receptor antagonist trials. Methods: We performed a phase 2, randomised, double-blind, placebo-controlled trial (NCT04380961) of US-based hospitalised adults (< 85 years) with laboratory-confirmed SARS-CoV-2 infection and severe (low levels of supplemental oxygen) or critical disease (high levels of oxygen supplementation). Patients received sirukumab 5 mg/kg or placebo single dose IV on Day 1 plus standard of care. The primary endpoint was time to sustained clinical improvement up to Day 28 based on an ordinal scale. Secondary endpoints included clinical improvement, all-cause mortality, and safety. Following an interim analysis, the protocol was amended to only recruit patients with critical COVID-19. Findings: From May 2020 to March 2021, 209 patients were randomised; 112 had critical disease (72 sirukumab, 40 placebo) at baseline. Median time to sustained clinical improvement in critical patients was 17 and 23 days in the sirukumab and placebo groups (HR, 1∙1; 95% CI, 0∙66–1∙88; p > 0∙05). At Day 28, 59∙4% versus 55∙0% of patients achieved clinical improvement with sirukumab versus placebo and rates of all-cause mortality were 24∙6% versus 30∙0%, respectively. Rates of grade ≥ 3 adverse events were comparable between the sirukumab and placebo groups (25∙9% vs 32∙9%; all patients). Interpretation: In critical COVID-19 patients who received sirukumab, there …
