Take a deep breath: UVA health system opens clinical trial of emphysema treatment

14.12.2005


Doctors at the University of Virginia Health System have opened a new clinical trial to try and help people with emphysema breathe better. The study will test the safety and effectiveness of a bronchoscopic valve, an experimental device designed to channel air to healthier portions of the lung. The idea is to improve a patient’s physical functioning, tolerance for exercise and general quality of life.



The study device works by limiting airflow to a selected portion of the lung in patients with emphysema. The bronchoscopic valve is implanted without an incision, hopefully providing an alternative to lung volume reduction surgery. The device is a small valve shaped like an umbrella. It’s placed in the bronchial tree to prevent air from entering targeted sections of the lung. Doctors successfully implanted the device in UVa’s first patient Dec. 2, the first time the device has been used in a clinical trial in the Southeast.

“UVa was selected to participate in this important study because of our extensive experience in treating patients with emphysema,” said Dr. Jonathon Truwit, professor of internal medicine and head of pulmonary and critical care medicine at UVa. “This is a large patient population with a need for new treatment options. As one of just twenty medical centers in the world participating in the trial, we are pleased to be involved in this innovative study.”


Lung disease is a growing health problem in the U.S. and around the world. According to the American Lung Association (ALA), 110,000 Americans die each year from chronic obstructive pulmonary disease or COPD, the fourth leading cause of death by disease in the U.S. Emphysema is the most serious form of this disease and is usually caused by cigarette smoking. According to the ALA, about three million Americans have been diagnosed with emphysema in recent years.

This lung disease begins with the destruction of air sacs called alveoli where oxygen from the air is exchanged for carbon dioxide in the blood. As these air sacs are destroyed, the lungs are able to transfer less and less oxygen to the bloodstream, causing shortness of breath. The lungs also lose their elasticity, which is important to keep airways open. Emphysema doesn’t develop suddenly. Years of exposure to the irritation of cigarette smoke usually precede its development.

The trial is sponsored by the developer of the valve, Spiration, Inc. For more information about this study, contact Peggie Donowitz at UVa at (434) 982-1801 or by email at mew5u@virginia.edu.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
