Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon May 2026

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

Optimizing Antibiotic Stewardship In Pneumonia: Evidence-Based Protocols For Enhanced Treatment And Resistance Reduction In A University-Affiliated Community Hospital, Carlos Luis Alejos, Jennifer Rojas Huen, Joan Beatrice Capellan, Ricardo Serna, Tejaswini Swamy, Jose Campo Maldonado

Research Colloquium

Introduction: National guidelines recommend early, targeted diagnostics such as respiratory viral panels, procalcitonin testing, Methicillin resistant staphylococcus aureus (MRSA) nasal swabs, and sputum cultures, for the effective management of pneumonia. However, our retrospective review at a university-affiliated community hospital revealed inconsistent application of these tools. These may contribute to excessive use of broad-spectrum antibiotics, higher costs, and increased antimicrobial resistance. The reason is that we aim to implement a standardized pneumonia order set in the electronic medical record (EMR) to improve diagnostic accuracy and antibiotic stewardship.

Methods: We conducted a retrospective chart review of adult inpatients admitted with community-acquired, hospital-acquired, …

Influenza-associated pulmonary aspergillosis (IAPA) is a feared complication in patients with influenza tracheobronchitis, especially those receiving corticosteroids. Herein, we established a novel IAPA mouse model with low-inoculum Aspergillus infection and compared outcomes in mice with and without cortisone acetate (CA) immunosuppression. CA was an independent predictor of increased morbidity/mortality in mice with IAPA. Early antifungal treatment with liposomal amphotericin B was pivotal to improve IAPA outcomes in CA-immunosuppressed mice, even after prior antiviral therapy with oseltamivir. In summary, our model recapitulates key clinical features of IAPA and provides a robust preclinical platform to study the pathogenesis and treatment of IAPA.

BACKGROUND: Community-onset bacterial coinfection in adults hospitalized with coronavirus disease 2019 (COVID-19) is reportedly uncommon, though empiric antibiotic use has been high. However, data regarding empiric antibiotic use and bacterial coinfection in children with critical illness from COVID-19 are scarce.

METHODS: We evaluated children and adolescents agedadmission, we adjudicated whether patients had community-onset bacterial coinfection. We compared demographic and clinical characteristics of those who did and did not (1) receive antibiotics and (2) have bacterial coinfection early in admission. Using Poisson regression models, we assessed factors associated with these outcomes.

RESULTS: Of the 532 patients, 63.3% received empiric antibiotics, but …

Antibiotic-associated diarrhea (AAD) is a common side effect of antibiotics. We examined the gastrointestinal microbiota in children treated with β-lactams for community-acquired pneumonia. Data were from 66 children (n = 198 samples), aged 6-71 months, enrolled in the SCOUT-CAP trial (NCT02891915). AAD was defined as ≥1 day of diarrhea. Stool samples were collected on study days 1, 6-10, and 19-25. Samples were analyzed using 16S ribosomal RNA gene sequencing to identify associations between patient characteristics, microbiota characteristics, and AAD (yes/no). Nineteen (29%) children developed AAD. Microbiota compositional profiles differed between AAD groups (permutational multivariate analysis of variance, P < .03) and across visits (P < .001). Children with higher baseline relative abundances of 2 Bacteroides species were less likely to experience AAD. Higher baseline abundance of Lachnospiraceae and amino acid biosynthesis pathways were associated with AAD. Children in the AAD group experienced prolonged dysbiosis (P < .05). Specific gastrointestinal microbiota profiles are associated with AAD in children.

Antimicrobial Stewardship Meets Transitions Of Care: Defining Length Of Therapy For Community-Acquired Pneumonia (Cap), Christopher Whitman, Sarah E. Moore, Matthew Song, Brian C. Bohn, Ashley M. Wilde

The University of Louisville Journal of Respiratory Infections

Introduction: Hospital-based antimicrobial stewardship efforts have traditionally focused on inpatient settings. Antibiotic prescribing at discharge is often an overlooked area of focus for antimicrobial stewardship programs. Discharge prescribing optimization is necessary to combat antibiotic overuse.

Methods: This was an observational, retrospective cohort study at a four–adult community hospital system. Four hundred adult patients admitted with community-acquired pneumonia and discharged with antibiotics were included. The primary outcome was overall (inpatient and discharge) antibiotic length of therapy. The secondary outcome was percentage of patients discharged on a fluoroquinolone who had not received one in the hospital. Descriptive statistics were utilized.

Results: The …

Covid-19 Case Complicated With Organizing Pneumonia And Pneumothorax: A Case Report, Tammy E. Phillips, Hammad A. Bhatti, Minh Q. Ho Apr 2022

Covid-19 Case Complicated With Organizing Pneumonia And Pneumothorax: A Case Report, Tammy E. Phillips, Hammad A. Bhatti, Minh Q. Ho

The University of Louisville Journal of Respiratory Infections

Organizing pneumonia can be idiopathic or caused by multiple etiologies, including viral or bacterial pneumonia, drugs, and autoimmune disorders. It can rarely lead to cyst formation and pneumothorax with the exact mechanism remaining unclear. This case presents a previously healthy 50-year-old male who contracted COVID-19 with subsequent development of organizing pneumonia and pneumothorax. Patients presenting with hypoxic respiratory failure due to COVID-19 should be screened for organizing pneumonia upon discharge. This case also illustrates the importance of following such patients radiologically to monitor interstitial lung disease and consider pneumothorax for patients re-presenting with acute symptoms.

Social Intervention By The Numbers: Evidence Behind The Specific Public Health Guidelines In The Covid-19 Pandemic., Michael P. Savage, David L. Fischman, Mamas A. Mamas

Department of Medicine Faculty Papers

Coronavirus disease 2019 (COVID-19) has rapidly become a worldwide pandemic ushering in a global health and economic crisis. In the absence of vaccines or definitive drug therapies, current strategies against COVID-19 rely on preventing the transmission of disease through nonpharmaceutical interventions such as social distancing and proper hand hygiene. For practical and perhaps ethical reasons, the clinical efficacy of these public health measures for managing pandemics has not been demonstrated in randomized controlled clinical trials. Accordingly, guideline recommendations for using nonpharmaceutical interventions are based primarily on observational and modeling studies and on expert opinion. A recent position paper from the …

Use Of Ultrasound For Diagnosis Of Pneumonia In Adults, A Review, Dafang Chen, Rodrigo Cavallazzi

The University of Louisville Journal of Respiratory Infections

Pneumonia is a common lung infection with significant morbidity and mortality. Currently, the diagnosis of pneumonia is made by patient history confirmed with chest radiograph or computed tomography. These modalities, however, have limitations including low accuracy, radiation exposure, and high cost. Lung ultrasound has become more prevalent in evaluating pulmonary conditions and has shown to be highly accurate in the diagnosis of pneumonia. The purpose of this review is to discuss sonographic findings associated with pneumonia, techniques used to obtain quality images, and the evidence in literature supporting the use of lung ultrasound in the diagnosis of pneumonia. Numerous studies …
