Genetic Determinants of Ankylosing Spondylitis Severity
This study will explore how genes-units of heredity-may influence the severity of ankylosing spondylitis. It will examine whether some genes may cause people with ankylosing spondylitis to have more rapid fusion of the bones of the spine, more difficulty performing daily activities, or be more likely to need joint surgery.

Literacy in Arthritis Management
This study will test a new patient education program designed for people who do not read well. It will also look at how poor reading skills affect a person’s health and how people who do not read well learn best. We will randomly assign patients who have a rheumatic condition…

Evaluation of Hydroxyurea Plus L-arginine or Sildenafil to Treat Sickle Cell Anemia
Patients with sickle cell disease have abnormal hemoglobin (the protein in red blood cells that carries oxygen to the body). This abnormality causes red blood cells to take on a sickle shape, producing disease symptoms. Fetal hemoglobin, a type of hemoglobin present in fetuses and babies, can prevent red cells…

Ozone and Rhinovirus-Induced Disease in Asthmatics
In the U.S., morbidity associated with human rhinovirus (RV) infection represents a major health problem. In asthmatics, up to 80% of asthma exacerbations are associated with upper respiratory infections. Despite evidence that environmental oxidant pollutants, such as ozone, may increase the severity of viral disease, the mechanisms underlying such an…

Effect of Ventilation-Feedback Training on Exercise Performance in COPD
The primary objective of the study is to determine whether individuals with Chronic Obstructive Pulmonary Disease (COPD) who complete ventilation-feedback training combined with a moderately-high intensity exercise and upper body strength program will demonstrate significantly longer exercise duration on a constant work rate treadmill test when compared to subjects who…

Role of Role of Genetic Factors in the Development of Lung Disease
This study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. Official Title Role of Genetic Factors in the Pathogenesis of Lung Disease Conditions –…

Sample Collections from the Airways of Asthmatic Patients
Fiberoptic bronchoscopy is a procedure which involves passing a pencil-thin tube into the lung in order to collect fluid and cells from the airways. Fiberoptic bronchoscopy can collect cells from the walls of airways by gently brushing them (bronchial brushing). In addition, squirting small amounts of sterile water in to…
