The Phase 3 randomized controlled trial, TBTC Study 31/ACTG A5349 (NCT02410772) demonstrated that a 4-month rifapentine-moxifloxacin regimen for drug-susceptible pulmonary tuberculosis was safe and effective. The primary efficacy outcome was 12-month tuberculosis disease free survival, while the primary safety outcome was the proportion of grade 3 or higher adverse events during the treatment period. We conducted an analysis of demographic, clinical, microbiologic, radiographic, and pharmacokinetic data and identified risk factors for unfavorable outcomes and adverse events. Among participants receiving the rifapentine-moxifloxacin regimen, low rifapentine exposure is the strongest driver of tuberculosis-related unfavorable outcomes (HR 0.65 for every 100 µg∙h/mL increase, …

Optimizing pyrazinamide dosing is critical to improve treatment efficacy while minimizing toxicity during tuberculosis treatment. Study 31/AIDS Clinical Trials Group A5349 represents the largest phase 3 randomized controlled therapeutic trial to date for such an investigation. Objectives: We sought to report pyrazinamide pharmacokinetic parameters, risk factors for lower pyrazinamide exposure, and relationships between pyrazinamide exposure and efficacy and safety outcomes. We aimed to determine pyrazinamide dosing strategies that optimize risks and benefits. Methods: We analyzed pyrazinamide steady-state pharmacokinetic data using population nonlinear mixed-effects models. We evaluated the contribution of pyrazinamide exposure to long-term efficacy using parametric time-to-event models and safety …

Long-acting technologies (LATs) for hepatitis C virus (HCV) are under development as a strategy to improve linkage to care, treatment adherence and outcomes. We conducted a survey of HCV treatment prescribers and HCV policymakers in low- and middle-income countries (LMICs) regarding acceptability and feasibility of HCV LATs. We included one-time intramuscular injection, subdermal implant and transdermal patch as potential LAT options. We surveyed participants regarding optimal health system and patient characteristics, concerns, potential barriers, overall feasibility and preferences for HCV LAT as compared to daily oral medication. Overall, 122 providers and 50 policymakers from 42 LMICs completed the survey. Among …

Unraveling The Effects Of The Covid-19 Pandemic On Staphylococcus Aureus Carriage: A Comparative Research Of Pre- And Post-Pandemic Samples, Catherine G. Johnston

Honors Undergraduate Theses

The COVID-19 pandemic brought about significant changes in the epidemiology of Staphylococcus aureus carriage and disease. This study aims to assess these changes by leveraging respiratory samples collected from a longstanding cohort, comparing the genomic characteristics of S. aureus isolates from pre- and post-pandemic periods. We analyzed S. aureus genomes and phenotypically determined macrolide resistance to characterize population structure, antibiotic resistance, and virulence profiles. Changes in S. aureus carriage rates, macrolide resistance, disease occurrence, and population structure between samples collected pre- and post-pandemic were examined. By using respiratory samples, chart reviews, and risk factor questionnaires of 498 children from a …

Introduction - The majority of active Mycobacterium tuberculosis cases are pulmonary, but extrapulmonary tuberculosis (TB) can account for up to 30% of active cases. Cases of tuberculosis myositis are rare and account for less than three percent of active cases and diagnosis is often delayed due to its rarity. We present a case of TB myositis and discuss the difficulties in diagnosis Case - Patient is an 82-year-old Vietnamese speaking female with hypertension and hyperlipidemia who presented for acute onset of nausea and vomiting in setting of three-month history of recurrent left lower extremity (LLE) swelling without systemic symptoms such …

Section of Pulmonary & Critical Care

Background and objective: Fungal empyema is a rare entity which is associated with high mortality. It is mostly seen in immune-compromised hosts. However, there is limited data available on fungal empyema from developing countries regarding risk factors, treatment, and outcome. This study was conducted to determine the risk factors, clinical features, treatment, and outcome of fungal empyema.
Methods: A retrospective observational study was performed on proven fungal empyema cases, admitted at Aga Khan University Hospital, Karachi, Pakistan during January 2018 to May 2021. We excluded all those patients with polymicrobial bacterial and fungal empyema or with negative pleural fluid cultures. …

This species possesses a high risk for persistent infection and candidemia. An uncommon complication of invasive candidiasis is spondylodiscitis and can rarely affect the cervical spine.

Case Presentation

The patient is a female in her late 50s with a complex medical history inclusive of chronic obstructive pulmonary disease, chronic pain, multiple abdominal surgeries, prolonged intensive care unit admission, and administration of total parenteral nutrition and broad-spectrum antibiotics who presented with complaints of worsening neck pain. She was last hospitalized 3 …

Significance Of Chronic Kidney Disease On Morbidity And Mortality In Hospitalized Patients With Covid-19, Varsha Suresh, Alexis Finer, Aarushi Varshney, Kay Thi Khine, Ishak Mansi, Abdo Asmar

HCA Healthcare Journal of Medicine

Background

Patients with comorbid illnesses are at risk for worse outcomes with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; COVID-19). Our research examined patients with chronic kidney disease (CKD) to establish whether it remains an independent risk factor for mortality and morbidity in patients with COVID-19.

Methods

We conducted a retrospective cohort study using an electronic patient database in 2020. An observational dataset from 149 hospitals comprising a United States-based health system (HCA Healthcare) was analyzed. Hospitalized patients (N=11 086), aged 18 and above, with a COVID-19 polymerase chain reaction positive result between January 1, 2020, and September 1, …

Syndromic Antibiograms And Nursing Home Clinicians' Antibiotic Choices For Urinary Tract Infections, Brigid M. Wilson, Taissa A. Bej, Robin L.P. Jump

Faculty Scholarship

Importance: Empirical antibiotic prescribing in nursing homes (NHs) is often suboptimal. The potential for antibiograms to improve empirical antibiotic decision-making in NHs remains poorly understood. Objective: To determine whether providing NH clinicians with a urinary antibiogram improves empirical antibiotic treatment of urinary tract infections (UTIs). Design, Setting, and Participants: This was a survey study using clinical vignettes. Participants were recruited via convenience sampling of professional organization listservs of NH clinicians practicing in the US from December 2021 through April 2022. Data were analyzed from July 2022 to June 2023. Interventions: Respondents were randomized to complete vignettes using a traditional antibiogram …

Recurrent Polymicrobial Bloodstream Infections As Harbingers Of A Duodenal-Inferior Vena Cava Fistula, Gregory E. Koval, Richard J. Hankins, Jasmine R. Marcelin

Graduate Medical Education Research Journal

This is a case of an 82-year-old patient who presented with recurrent polymicrobial bloodstream infections and no obvious undrained source of infection. She had prior double barrel iliocaval stenting for post thrombotic syndrome. The patient underwent exploratory laparotomy and primary repair of a duodenal-caval fistula with a fascia lata patch and an omental pedicle flap. No further bloodstream infections were documented after the repair. This discussion highlights an uncommon complication of IVC stenting, its presentation as well as the operative approach used to repair the fistula.

Determinants Of Immunization In Polio Super High-Risk Union Councils Of Pakistan, Ahmad Khan, Imtiaz Hussain, Dale A. Rhoda, Muhammad Umer, Uzair Ansari, Imran Ahmed, Caitlin Clary, Rana Muhammad Safdar, Sajid Bashir Soofi

Centre of Excellence in Women and Child Health

Background: The current polio epidemiology in Pakistan poses a unique challenge for global eradication as the country is affected by ongoing endemic poliovirus transmission. Across the country, 40 union councils (UCs) which serve as core reservoirs for poliovirus with continuous incidences of polio cases are categorized as super-high-risk union councils (SHRUCs).
Methodology: A cross-sectional survey was conducted in 39 SHRUCs using a two-stage stratified cluster sampling technique. 6,976 children aged 12-23 months were covered. A structured questionnaire was used for data collection. Data were analyzed using STATA version 17.
Results: Based on both vaccination records and recall, 48.3% of children …
