Peripheral Blood Biomarkers For Rheumatoid Arthritis-Associated Interstitial Lung Disease, Brent A. Luedders Dec 2025

Peripheral Blood Biomarkers For Rheumatoid Arthritis-Associated Interstitial Lung Disease, Brent A. Luedders

Theses & Dissertations

Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a common extra-articular complication of rheumatoid arthritis (RA). Measuring peripheral blood biomarkers represents an appealing strategy to inform the screening and prediction of RA-ILD. In these studies, I aimed to further characterize the associations of peripheral blood biomarkers with prevalent and incident RA-ILD. First, I evaluated the associations of matrix metalloproteinases (MMPs) with RA-ILD among a multicenter cohort of RA U.S. Veteran patients (n = 2,312). Higher concentrations of MMP-7 and MMP-9 were independently associated with both prevalent and incident RA-ILD, including a nearly four-fold increased odds of prevalent RA-ILD (adjusted odds ratio …

Rheumatoid Arthritis Disease Activity Is Associated With Frailty In Veterans, Courtney N. Loecker Aug 2024

Rheumatoid Arthritis Disease Activity Is Associated With Frailty In Veterans, Courtney N. Loecker

Theses & Dissertations

Frailty, a physiologic vulnerability to everyday stressors, affects approximately 30% of the 1.3 million Americans with rheumatoid arthritis (RA) and is associated with increased risk for adverse health outcomes. Active RA manifests as inflammation, pain, and joint damage leading to functional impairments and morbidity which cumulatively influences frailty. However, the relationship between RA disease activity and frailty is incompletely understood.

This study evaluated the relationship of RA disease activity and frailty at baseline and over up to five years in Veterans. A cohort study was performed using data from the Veterans Affairs Rheumatoid Arthritis registry. RA disease activity was measured …


Serum Antibodies To Periodontal Pathogens And Anti-Malondialdehyde-Acetaldehyde: Potential Role In The Interrelationship Between The Periodontium And Rheumatoid Arthritis, Joyce Lee May 2024

Serum Antibodies To Periodontal Pathogens And Anti-Malondialdehyde-Acetaldehyde: Potential Role In The Interrelationship Between The Periodontium And Rheumatoid Arthritis, Joyce Lee

Theses & Dissertations

Objectives: Study 1 – To quantify associations between anti-Porphyromonas gingivalis, anti-Prevotella intermedia, and anti-Fusobacterium nucleatum serum antibody concentrations and risk of developing rheumatoid arthritis (RA). Study 2 – To test if periodontal clinical measures, alveolar bone loss (ABL), and the aforementioned serum anti-bacterial antibody concentrations are associated with anti-malondialdehyde-acetaldehyde (MAA) serum antibody concentrations.

Methods: Study 1 – Serum samples pre- and post- RA diagnosis (n=214 cases, 210 matched controls) from the U.S. Department of Defense Serum Repository were utilized to compare timing of elevations of anti-bacterial antibody concentrations relative to RA diagnosis and associations …


Citrullinated And Malondialdehyde-Acetaldehyde Modified Proteins Promote Cellular Inflammatory And Fibrotic Responses Associated With Rheumatoid Arthritis, Nozima Aripova Dec 2023

Citrullinated And Malondialdehyde-Acetaldehyde Modified Proteins Promote Cellular Inflammatory And Fibrotic Responses Associated With Rheumatoid Arthritis, Nozima Aripova

Theses & Dissertations

Rheumatoid arthritis (RA) is a systemic, autoimmune disease primarily characterized by perpetual synovial inflammation that results in synovial tissue proliferation and fibrosis (pannus). Although joint involvement is the predominant manifestation of RA, extra-articular features, such as interstitial lung disease (ILD), contribute significantly to the elevated mortality associated with the condition. Post-translational modifications play a significant role in RA and RA-ILD pathogenesis. Circulating anti-citrullinated protein antibodies (ACPAs) are a highly diagnostic tool implicating a potential role for citrullinated antigens in RA and RA-ILD.

Recently, antibodies to malondialdehyde acetaldehyde adducts (MAA) have been markedly elevated in patients with RA and RA-ILD. MAA …


Multi-Digit Auto-Amputation In Setting Of Mixed Connective Tissue Disease, Kishan P. Patel, Jennifer L. Medlin, Michelene Hearth-Holmes Dec 2020

Multi-Digit Auto-Amputation In Setting Of Mixed Connective Tissue Disease, Kishan P. Patel, Jennifer L. Medlin, Michelene Hearth-Holmes

Graduate Medical Education Research Journal

Raynaud’s disease is a cutaneous manifestation often present in various connective tissue and vascular diseases. Depending on the age of onset and acuity of symptoms, the phenomenon can provide clinicians with some insight as to the severity of underlying disease, including the distinction between primary and secondary Raynaud’s. However, this diagnostic approach seems to have its limitations regarding efficacy and timing of treatment. Traditionally, treatment of Raynaud’s has focused on reestablishing blood perfusion to affected tissue, which has previously been achieved with vasodilatory medications and site-specific surgical intervention. In lieu of the severe sequelae of Raynaud’s in the setting of …


Enhancing The Identification Of Rheumatoid Arthritis-Associated Lung Disease, Bryant England Dec 2019

Enhancing The Identification Of Rheumatoid Arthritis-Associated Lung Disease, Bryant England

Theses & Dissertations

Rheumatoid arthritis (RA) is a systemic autoimmune disease that predisposes afflicted individuals to reduced quality of life, physical disability, and premature mortality. While joint involvement is the primary manifestation of RA, extra-articular features including lung disease are responsible for a significant portion of the excess mortality. In this dissertation I demonstrate the contribution of chronic lung diseases to premature mortality in RA, contrasting with the more widely recognized comorbidity in RA of cardiovascular disease. Then, I establish that a novel serum biomarker, anti-malondialdehyde-acetaldehyde adduct (MAA) antibody, is associated with the presence of interstitial lung disease (ILD) in RA subjects. Further …


Factors Associated With Participant Attrition In A Longitudinal, Survey-Based Rheumatic Disease Databank, Kathryn A. Grafel Dec 2018

Factors Associated With Participant Attrition In A Longitudinal, Survey-Based Rheumatic Disease Databank, Kathryn A. Grafel

Capstone Experience: Master of Public Health

Introduction: Participant attrition is a problem common to many longitudinal studies, and when it occurs nonrandomly, it can impact the study’s validity and generalizability. Identifying factors associated with attrition can help to detect bias and aid in developing targeted interventions to reduce attrition. Methods: Logistic regression and Cox proportional hazards regression models were constructed separately for patients with rheumatoid arthritis, systemic lupus erythematosus, and other rheumatic diseases who participated in the FORWARD study between 1998 and 2018. Results: Patient characteristics associated with attrition included male sex, younger age, non-White race, and less education, each of which was identified in multiple …


Modifiable Barriers To Optimal Outcomes In Gout Management, Brian W. Coburn May 2016

Modifiable Barriers To Optimal Outcomes In Gout Management, Brian W. Coburn

Theses & Dissertations

Improving patient outcomes in chronic disease is of critical importance to the future of health care. Gout, affecting 4% of the US population, is a highly treatable chronic disease from which patients experience unnecessarily suboptimal outcomes. In this dissertation, I demonstrate how interrelated patient and provider factors affect patient outcomes in gout. First, I describe how only 14% of gout patients know their serum urate (SU) goal for urate lowering therapy (ULT) despite otherwise being knowledgeable about gout and its treatment. I then demonstrate the importance of multiple patient and provider factors in achieving SU goal. Specifically, I demonstrate that …
