The Role Of The Complement System In Cigarette Smoke Induced Emphysema Development And Progression, Sarah E. Stephenson
The Role Of The Complement System In Cigarette Smoke Induced Emphysema Development And Progression, Sarah E. Stephenson
MUSC Theses and Dissertations
Emphysema is a complex inflammatory condition of the respiratory tract with an incompletely elucidated pathogenesis. Due to the complexity of the disease, treatment options are limited for patients and have poor efficacy. Therefore a greater understanding of disease pathogenesis is imperative to expand therapeutic strategies. Central to disease development is the activation of the innate and adaptive immune system, however, targeting blockade of only one side of the immune response, has shown little clinical benefit. The complement system, while regarded as an innate immune mechanism, can modulate both innate and adaptive immune responses. Given these dual modulatory effects, the complement …
Perceptions Of Social Isolation And Social Support In Alpha-1 Antitrypsin Deficiency And Sarcoidosis: Results Of A Mixed-Methods Study, Susan Krause Flavin
Perceptions Of Social Isolation And Social Support In Alpha-1 Antitrypsin Deficiency And Sarcoidosis: Results Of A Mixed-Methods Study, Susan Krause Flavin
MUSC Theses and Dissertations
Purpose: The purpose of this dissertation was to explore perceptions of social isolation and social support in individuals with one of two rare lung conditions, alpha-1 antitrypsin deficiency (AATD) or sarcoidosis. First, a dimensional concept analysis was conducted to identify key factors contributing to the phenomenon of social isolation. Next, an integrative review of existing instruments to measure social isolation was conducted to identify the most appropriate instrument for the study. Finally, a mixed-methods study was conducted to explore these phenomena in the two populations of interest. Problem: Many rare diseases are chronic, complex and associated with other disabilities (M. …
Relationship Of Main Pulmonary Artery Diameter To Pulmonary Arterial Pressure In Scleroderma Patients With And Without Mild To Moderate Interstitial Fibrosis, Robert Kane Mccall
Relationship Of Main Pulmonary Artery Diameter To Pulmonary Arterial Pressure In Scleroderma Patients With And Without Mild To Moderate Interstitial Fibrosis, Robert Kane Mccall
MUSC Theses and Dissertations
Purpose: To determine the validity of main pulmonary artery diameter (MPAD) as a marker of pulmonary hypertension in scleroderma patients with and without interstitial lung disease (lLD). Materials and Methods: We cross-referenced the radiologic database with medical records to identify patients with both computed tomography (CT) scans of the chest and right-heart catheterization separated by no more than six months. Computed tomography scans were reviewed to determine MPAD and extent of ILD for each patient. Ground glass opacity and fibrosis were individually scored by a single thoracic radiologist on a five-point scale. The same radiologist also determined the quality of …
Reducing Lung Disease In Cystic Fibrosis: Model Systems And Anti-Inflammatory Treatment, Scotty Mcglothlin Buff
Reducing Lung Disease In Cystic Fibrosis: Model Systems And Anti-Inflammatory Treatment, Scotty Mcglothlin Buff
MUSC Theses and Dissertations
Cystic fibrosis (CF), the most common lethal autosomal recessive disease in Caucasians resulting in a median life span of approximately 35 years, is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR). The primary cause of morbidity and mortality is respiratory failure caused by progressive obstructive lung disease. CF airway disease is characterized by the abundance of pro inflammatory cells, chemokines and cytokines with a deficiency of regulatory/anti-inflammatory cytokine interleukin 10 (lL10). We hypothesized that CF airway obstruction originates from excessive inflammation and gene transfer of IL-I0 would decrease inflammation in the airways of mice infected with Pseudomonas …

Secondary Surfactant Dysfunction And Deficiency, Robin Louise Bissinger
MUSC Theses and Dissertations
Based on literature in Adult Respiratory Distress Syndrome in humans and evidence of surfactant activation in vitro and vivo, and our clinical observations of secondary respiratory decompensation in premature infancies recovering from RDS, a study was designed to look at the possibility of benefit from secondary surfactant administration in premature infancies with secondary decompensation after recovery from respiratory distress syndrome (RDS). A prospective pilot study was performed to study the effects of secondary surfactant administration on oxygenation, ventilation and pulmonary function of neonates who had respiratory decompensation after recovery from RDS. A secondary data analysis was performed looking at pulmonary …
On The Utility Of Stochastic Models Of Chronic Obstructive Pulmonary Disease, Rebecca Boehm
On The Utility Of Stochastic Models Of Chronic Obstructive Pulmonary Disease, Rebecca Boehm
MUSC Theses and Dissertations
Chronic obstructive pulmonary disease (COPD) is a progressive and irreversible lung disease characterized by reduced lung function, abnormal inflammatory response, dyspnea, increased sputum production, and costly and debilitating exacerbations. Common treatments for COPD include smoking cessation therapy, short- and long-acting bronchodilators, inhaled corticosteroids, pulmonary rehabilitation, and home oxygen therapy. However, a recent meta-analysis demonstrated that inhaled corticosteroids fail to slow the decline in FEV1, the primary clinical marker of COPD progression. In addition, some evidence exists to suggest that long-term inhaled corticosteroid use may increase bone density loss, leading to osteoporosis. Given that the bone health effects of inhaled corticosteroid …
Immunopathogenesis Of A Spectrum Of Inflammatory Lung Diseases Induced By Experimental Reovirus Infection, Stephen Clifford Bellum
Immunopathogenesis Of A Spectrum Of Inflammatory Lung Diseases Induced By Experimental Reovirus Infection, Stephen Clifford Bellum
MUSC Theses and Dissertations
Inflammatory lung diseases cause a significant amount of morbidity and mortality. However, the mechanisms that control the initiation and resolution of pulmonary inflammatory responses have not been well-elucidated. Histopathological data suggests that the lung responds with a similar pattern of inflammation to diverse range of injurious stimuli. In order to investigate the immunopathogenesis of lung inflammation, a series of in vivo models of lung inflammation were generated in CBA/J and CD-I mice by respiratory reovirus 1/L infection. Using this approach, it was observed in CBA/J mice that a relatively low titer of reovirus 1/L induced a pattern of intraluminal fibrosis …
