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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
