Asthma vs. COPD, similar symptoms -- Different causes and treatment

07.11.2014

Fifty percent of older adults may suffer from both

Coughing, wheezing and shortness of breath are symptoms asthma sufferers are used to. They are also the symptoms of chronic obstructive pulmonary disease (COPD). For sufferers, as well as physicians, it can be difficult to tell the difference between the two conditions.

According to a presentation at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting, as many as 50 percent of older adults with obstructive airway disease have overlapping characteristics of asthma and COPD. And this percentage increases as people get older.

"Based on symptoms alone, it can be difficult to diagnose COPD vs. asthma. The pathway to a diagnosis of COPD or asthma - smoking vs. a long-term persistence of asthma - can be quite different," said allergist William Busse, MD, ACAAI fellow and presenter.

"In every patient, but in older patients in particular, we need to take a thorough history and perform a physical examination, as well as measurements of lung functions. In patients with COPD and asthma, the changes in lung function may be severe, and it is not often readily apparent, which is the predominant, underlying condition - asthma or COPD. Treatment will differ depending on diagnosis."

Lung function changes in asthma are due to airway inflammation, and treatment is directed at reducing inflammation with corticosteroids - largely, inhaled corticosteroids. But the changes in lung function associated with COPD are caused by cigarette smoking and, except with an exacerbation, are not particularly responsive to corticosteroids.

"The primary treatment in COPD is bronchodilators, including long-acting beta agonists. They help relax muscles around the airways in the lungs, allowing air to flow more freely," said allergist Michael Foggs, MD, ACAAI president. "They should not be given alone to people with asthma.

In COPD, but not asthma, inhaled corticosteroids have been associated with an increased risk for pneumonia and in some cases, features of both asthma and COPD exist. For these patients a combination of inhaled corticosteroids and long-acting beta agonists is usually best."

Some treatments for COPD and asthma are similar. Bronchodilators are used for both conditions. Other treatments tend to be more condition-specific. People with asthma are encouraged to avoid their personal triggers, like keeping pets out of the home or avoiding the outdoors when allergen concentrations are high. While people with COPD are also encouraged to avoid triggers, the emphasis in this condition is to stop smoking. Similarly, if a patient has asthma, smoking makes the underlying disease worse and reduces the response to inhaled corticosteroids.

Allergists who treat these conditions recognize that each patient, and their symptoms, must be treated according to their unique set of circumstances. People need to tell their allergists all their symptoms and complete medical history in order to receive the correct diagnosis and appropriately tailored therapy.

About ACAAI

The ACAAI is a professional medical organization of more than 6,000 allergists-immunologists and allied health professionals, headquartered in Arlington Heights, Ill. The College fosters a culture of collaboration and congeniality in which its members work together and with others toward the common goals of patient care, education, advocacy and research. ACAAI allergists are board-certified physicians trained to diagnose allergies and asthma, administer immunotherapy, and provide patients with the best treatment outcomes.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
