Huang, Justin J. Huang, Maiying Kong, Jiapeng Huang

The University of Louisville Journal of Respiratory Infections

Background

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is a rapidly evolving virus that can severely impact the cardiovascular system. With new variants, it is important to characterize wave-specific (defined by dominant circulating variants) clinical changes.

Methods

A multi-center retrospective cohort study of patients hospitalized with SARS-CoV-2 community acquired pneumonia at eight adult acute-care hospitals in the city of Louisville, KY was conducted. Patients hospitalized with Coronavirus Disease 2019 (COVID-19) community acquired pneumonia who experienced a cardiovascular event between March 2020 and July 2022 were included in this analysis. Variant assignment was based on temporal prevalence rather than genomic confirmation, and …

A Rare And Challenging Polymicrobial Pleural Infection Involving Cupriavidus Pauculus In A Patient With Rheumatoid Arthritis And Multiple Complications, Moiz Ahmed Khan, Syeda Samiya Kamal, Muhammad Muneeb, Summaya Zafar

The University of Louisville Journal of Respiratory Infections

A 58-year-old female with a 15-year history of rheumatoid arthritis (RA) and a history of treatment consisting of methotrexate, hydroxychloroquine, leflunomide, and chronic prednisolone therapy, presented with fever, productive cough, dyspnea, and left leg cellulitis. She developed septic shock complicated by tension pneumothorax requiring emergency thoracostomy and non-ST-elevation myocardial infarction (NSTEMI). Pleural fluid culture grew Cupriavidus pauculus, a rare environmental gram-negative bacillus, alongside Burkholderia cepacia and Candida parapsilosis, indicating polymicrobial infection which was most likely predisposed by patient's immunosuppressed state from RA and prolonged steroid use. Treatment consisted of trimethoprim/sulfamethoxazole, meropenem, fluconazole, and cardiopulmonary support, and culminated in …

North Texas GME Research Forum 2026

Peri-partum infective endocarditis (IE) is a rare but serious condition with high maternal and fetal morbidity and mortality. IE is exceedingly uncommon in young healthy patients, especially without any known risk factors such as intravenous (IV) drug use, congenital heart disease, or rheumatic heart disease. IE is estimated to complicate 0.00002% of in-hospital deliveries. Similar to the general population, staphylococcal and streptococcal species remain the most common pathogens in obstetric patients. Enterococcal species make up less than 10% of IE cases in pregnant women. Very few cases of enterococcal IE in the post-partum period are reported in the literature. We …

An Unusual Source Of A Lethal Pathogen: Paeniclostridium Sordellii Bacteremia In Acute Cholecystitis, Myrna Garcia, Leena Algarin, Olutoyin Abitoye, Rachel Gnanaprakasam

North Texas GME Research Forum 2026

Paeniclostridium sordellii is a spore-forming, gram-positive, anaerobic bacilli known for its highly virulent toxin production, often leading to fulminant sepsis and shock. It is most commonly associated with gynecologic infections and necrotizing soft tissue infections associated with intravenous drug use. However, reports of P. sordellii bacteremia in the setting of gall bladder infections are quite rare. This case report highlights an unusual presentation of P. sordellii infection with bloodstream infection originating from acute cholecystitis, demonstrating a non-fulminant clinical course and successful treatment with ceftriaxone.

A Hidden Culprit: Disseminated Tuberculosis Masquerading As Abdominal Abscesses, Sudiksha Veerareddy, Alex Hall, Urvi Sakhuja, Sarah Abuelayyan, Evangelista Ezenduka, Rinu Varghese

North Texas GME Research Forum 2026

Introduction: Tuberculosis (TB) is an insidious pulmonary infection that is most prevalent in developing countries. Primary TB may also become latent after initial infection and remain dormant in the body until the patient becomes immunocompromised. The infection will then resume and can become disseminated, moving hematogenously and through the lymphatics to other areas of the body. Disseminated TB is known to manifest in a variety of ways, making it difficult to diagnose.

Extra-Intestinal Clostridioides Difficile Abscess In A Small Bowel Gist: A Rare Tumor-Associated Complication, Nicholas Gerden, Pradip Gautam, Asad Rehman, Long Hoang

North Texas GME Research Forum 2026

Extra-intestinal infections caused by Clostridioides difficile are exceedingly rare and typically occur in settings that disrupt the gastrointestinal barrier, including recent gastrointestinal surgery, bowel perforation or microperforation, and severe colonic disease.

We present the case of a 75-year-old man with abdominal pain and hemoperitoneum in the setting of a suspected small bowel leak secondary to an intestinal mass. Computed tomography angiography revealed an 11.0 × 9.6 cm pelvic fluid collection, prompting exploratory laparotomy with drainage of a pelvic abscess and evacuation of hemoperitoneum. Intraoperatively, a small bowel perforation caused by a 4.4 cm gastrointestinal stromal tumor (GIST) was identified. Operative …
