An Observational Study to Assess Safety of Sulfamethoxazole + Trimethoprim + Guaifenesin (Balsamic Bactrim) in Adult Participants With Acute Bronchitis

This is a pilot, observational and multicentric study of safety of sulfamethoxazole plus (+) trimethoprim + guaifenesin (Balsamic Bactrim) in adult participants with acute bronchitis. Overall, 50 adult participants with acute bronchitis eligible for treatment with sulfamethoxazole + trimethoprim + guaifenesin will be enrolled. Administration of Balsamic Bactrim will be ...

Phase N/A

The Relationship Between GOLD Risk Group and Clinical Outcomes in a Community-based COPD Cohort

This study is designed to collect information on the current level of symptoms and ability to breathe, treatment and outcomes of patients with 1) Chronic Obstructive Pulmonary Disease (COPD), or 2) in current or former smokers with respiratory symptoms but preserved pulmonary function or 3) in current or former smokers ...

Phase N/A

Airway Macrophages and Sputum Milieu in Adult Subjects With Airflow Obstruction

In the United States, a variety of farming operations can generate significant amounts of dust. Chronic organic dust exposure to workers in this industry can result in several respiratory health conditions including chronic bronchitis, chronic obstructive pulmonary disease (COPD), and exacerbations of asthma. Organic dust is a complex mixture containing ...

Etiologies Investigations and Outcomes of Patients Presenting With Hemoptysis

RATIONALE Hemoptysis, mild or massive, is worrisome for both patients and physicians. The management is different depending on the causes, which are not well defined for the North American population. Despite the fact that this symptom is commonly reported in clinic, there are only a few studies published on this ...

Phase N/A

Examining the Genetic Factors That May Cause Chronic Obstructive Pulmonary Disease (COPD)

COPD is a disease in which the lung airways are damaged and partly obstructed, making it difficult to breathe. Millions of people in the United States have COPD, and it is the third leading cause of death in the United States. Symptoms include coughing, excess mucus production, shortness of breath, ...

Emphysema Research Registry

The Emphysema Research Center will enroll up to 3000 subjects at the University of Pittsburgh. The experimental procedures that will be conducted as a part of the Emphysema Research Registry include gathering basic personal information (e.g., name, address, phone number, etc.), asking basic screening questions (which may involve the examination ...

Phase N/A

Evaluating a Host-response Based Diagnostic for Distinguishing Between Bacterial and Viral Etiology in Patients With Lower Respiratory Tract Infection (LRTI)

The purpose of this study is to validate the diagnostic accuracy of a novel host-response based diagnostic tool for differentiating between bacterial and viral etiologies in adult patients aged 18 years and older with clinical suspicion of lower respiratory tract infections (LRTI)

Phase N/A

COPD Patient-Powered Research Network

The COPD Patient-Powered Research Network (COPD PPRN) is a patient research registry with the goal of enrolling 75,000 or more COPD patients and those at risk who are willing to share their heath information over several years and participate in research. The COPD PPRN has built an online platform to ...

Phase N/A

Multiple Breath Washout a Clinimetric Dataset

Lung Clearance Index (LCI) has been shown to be more sensitive and perhaps more applicable in early stages of lung disease when compared to currently utilised physiological outcome measures, and yet it is not approved by regulatory agencies as a recognised surrogate outcome measure. This may highlight some of the ...

Phase N/A

BROnchoalveolar Investigations of Never-smokers With Chronic Obstruction From the Swedish CardioPulmonary bioImage Study

Chronic Obstructive Pulmonary Disease (COPD) is an umbrella diagnosis defined by obstructive lung function impairments, and is likely to be caused by a multitude of etiologies including environmental exposures, genetic predispositions and developmental factors. Due to the heterogeneity of the disease, molecular and mechanistic sub-phenotyping of COPD represents an essential ...
