More attention should be given to patients who have chronic obstructive pulmonary disease (COPD) and concomitant asthma, after a study showed that nearly one-fifth of patients with COPD fall into this subtype.
Patients with overlap of the two conditions experienced poorer symptom control, had lower quality of life (QoL), and took part in less physical activity compared with other patients with COPD, despite having similar forced expiratory volume in 1 second (FEV1) values and less exposure to smoking.
"Clear diagnostic criteria and management guidelines for this phenotype must be developed and prospectively validated, and this phenotype should be incorporated in phenotype-guided management of COPD," say authors Marc Miravitlles (Vall d'Hebron University Hospital, Barcelona, Spain) and colleagues.
The study included data on 3885 participants aged 40-80 years who were part of the population-based EPI-SCAN study. Overall, 385 participants had COPD, defined as a post-bronchodilator FEV1/forced vital capacity ratio of less than 0.7, of whom 67 (17.4%) had also been diagnosed with asthma.
The authors found that patients with overlap COPD-asthma were more likely to be women (55.2 vs 24.2%), to never have smoked (56.7 vs 19.5%), and have a significantly higher body mass index (29.1 vs 27.8 kg/m2) than non-overlap patients. However, spirometry and 6-minute walking test results were similar between the two groups.

U.S.-born children have more allergies and asthma


Researchers surveyed the parents of 80,000 children in one of six languages and found that association held even after they took into account where families lived and how often they moved, as well as their race and income.
"This is definitely something we see clinically and we're trying to better understand, what is it in our environment that's increasing the risk of allergic disease?" said Dr. Ruchi Gupta, who studies allergies at the Northwestern University Feinberg School of Medicine in Chicago but wasn't involved in the new research.
"Food allergies have increased tremendously," she told Reuters Health. "We do see people who come from other countries don't tend to have it, but immigrants who are maybe second generation, they're identical (to U.S.-born people)."
It's not obvious what explains that pattern, researchers said.
According to Gupta, two possible culprits are the so-called hygiene hypothesis - which suggests kids in the U.S. are too clean, and their immune systems never get exposed to common allergens - or the poor quality of American diets.
Lead researcher Dr. Jonathan Silverberg from Beth Israel Medical Center and St. Luke's-Roosevelt Hospital Center in New York said climate, obesity and various infections might also be playing a role.
"The results of the study suggest that there are environmental factors in the U.S. that trigger allergic disease," he told Reuters Health in an email.
"Children born outside the U.S. are likely not exposed to these factors early in life and are therefore less likely to develop allergic diseases."
Surveys were completed by parents of kids and teens in 2007 and 2008. Just over 20 percent of children born outside the U.S. had any type of allergic disease - including asthma, eczema, hay fever or food allergies - compared to between 34 and 35 percent of those born in the U.S.
What's more, the risk of allergies increased with the more time foreign-born children spent in the U.S., Silverberg and his colleagues wrote in JAMA Pediatrics.
For example, 27 percent of foreign-born kids who had immigrated more than a decade earlier had any type of allergy, according to their parents' reports, versus 17 to 18 percent of those who had moved to the U.S. within the past two years.
"You acclimate to wherever you are and you pick up whatever is going on there," Gupta explained. "The findings here are very...

If you're among the 27 million North Americans with asthma, chances are it's triggered by allergies to airborne irritants in your environment (a whopping 75 percent of adults with sensitive airways have allergic asthma). Unfortunately, only 25 percent of people with asthma know what they're allergic to and how to avoid the triggers that make their airways constrict, swell and clog up with mucus. That may be why more than half of all PWA (people with asthma) have at least one asthma attack each year -- and why that scary "I can't breathe" feeling sends a half-million folks to the emergency room annually (and, we hate to add, needlessly kills thousands).
Clearly, if you have allergic asthma, identifying and avoiding your triggers -- and setting up a smart asthma treatment plan -- could be a lifesaver.
The allergens that are the most common wheezemakers include pollen (especially grass pollen), dust mites, mold, household pests like cockroaches and pets of all kinds. So you want to get hip to the asthma triggers and start hunting for your hazards.

Children with asthma should play hard in gym class and stop worrying they might have an attack that could leave them struggling to breathe, respiratory specialists are now recommending.
Physical activity by people with asthma isn’t harmful and might even be helpful to treating the condition, doctors in the field believe. A report published last year in the Cochrane Database Systems Review, a journal that reviews health-care treatments and decision making, looked at 19 previous studies of exercise and asthma and concluded that people with the respiratory condition fared well with physical activity. The studies’ results ranged from showing no difference in patients’ asthma control to an increase in the number of symptom-free days and a decrease in asthma severity.
Laboratory studies on animals with asthma also have shown that exercise appears to reduce the severity and frequency of attacks, says Timothy Craig, an immunologist and allergist at Pennsylvania State University College of Medicine in Hershey, Pa. The experiments with mice found that exercise calms the activity of inflammatory proteins and peptides in airways that, when stimulated, cause an attack, he says.
“If you have good, controlled asthma, you should be able to exercise,” Dr. Craig says.
Fear of physical activity is real for many asthma patients. Exercise can spur an attack, in which the airways get inflamed and lung muscles contract, making it hard for people to catch their breath. If untreated, serious cases can lead to death.

Spirometry, the most common type of pulmonary function test (PFT), is used to evaluate worker respiratory health in medical surveillance programs and to screen workers for their ability to perform certain tasks. Spirometry results can play a central role in decisions about worker job assignments and personal protective equipment, and in the assessment of exposure-related health effects.

Newcastle researchers say they have found a link between asthma and oestrogen in young obese women.
The Hunter Medical Research Institute's Hayley Scott says oestrogen stimulates leptin, a hormone that regulates hunger, but also promotes airway inflammation.
A study of 130 people found younger females tended to show a more hormone-related pattern of airway inflammation that is associated with higher levels of oestrogen.
Dr Scott says obesity is known to be a major risk factor for asthma but the relationship is not well understood.
"There is potential to modulate sex hormone levels in obese young women with asthma for improved management of their respiratory condition," she said.
"Neutrophilia (a form of airway inflammation) doesn't respond well to frontline asthma treatment with inhalers."
The findings were presented in Darwin at the annual scientific meeting of the Thoracic Society of Australia and New Zealand.

Study finds up to 75 percent of asthmatic adults have an allergy


More than 25 million American children, adolescents and adults currently have a diagnosis of asthma.  
Previously it was thought that underlying allergies were only prevalent in children with allergies. In fact, almost 80 percent of children with asthma have underlying allergies, so perhaps that was not necessarily the case with adults with asthma. 
However, a new study published in this month’s Annals of Allergy, Asthma and Immunology found that about 75 percent of asthma sufferers aged 20 to 40 years old and 65 percent of asthmatic adults aged 55 years and older, have at least one confirmed allergy.
The older asthmatic adults studied were found to be sensitive to indoor house dust mites (36 percent), followed by grass pollen (33 percent), cats (27 percent), dog (24 percent), and cockroaches (11 percent). 
The allergic sensitivities in those asthmatics studied in the 20-to 40-year-old groups were different: These younger patients were found to be sensitive to dogs (50 percent) and house dust mites (45 percent).
The medical community has long understood the relationship between having allergies and the risk of developing asthma especially in the younger population.  However, asthma is often not well diagnosed in older adults, and so many go untreated or under-treated. 
A misdiagnosis of asthma in an older adults leaves the potential for various associated health consequences.  Without optimal diagnosis and treatment, a potential increase in life-threatening asthma symptoms may be observed particularly in older adults, where other conditions are more prevalent, such as underlying heart diseases.
This study underscores the importance of looking at allergic triggers in older and younger individuals, as well as looking at genetic history and environmental modification in evaluating and treating asthmatic individuals.  
Testing for possible allergies and subsequent counseling regarding environmental allergy exposures need to be strongly considered in older patients with asthma.
For a long time it was considered that older patients with asthma were more likely to be characterized as being “non-allergic.” It appears from this review and others, there is increasing evidence of older individuals with asthma who are more likely to have underlying allergies. 
The take-home message from this study shows an even higher number of older adults with...
