The Latest Asthma Research
Asthma is a serious condition affecting millions of people. Its
rapid rise among all developed countries is cause for deep
concern. In response to this alarming trend, researchers are
working diligently to find more effective treatments for those
already diagnosed with the disease, and possibly a cure to stop
its progression.
According to the National Institute of Environmental Health
Sciences, "Asthma is a chronic lung disorder of enormous public
health importance that affects 10 to 12 percent of the
population; it disproportionately affects children, minorities,
and persons of lower socioeconomic status." Asthma is the
leading cause of school absences and the most common cause for
childhood emergency room visits. The economic cost of asthma
surpasses 12 billion dollars annually.
Despite an increase in our understanding of the progression of
the disease, the effects of allergy triggers on the body and the
way our bodies react to them, and the great strides in
diagnosing and treating asthma, the number of people diagnosed,
sick or that have died from the disease continues to rise.
Our lungs are filled with hollow tube like passages that
resemble the branches on a tree. These passages gradually become
smaller and smaller ending in tiny pockets where oxygen and
carbon dioxide are exchanged. For those with asthma, swelling in
the hollow tubes that fill the lungs makes breathing difficult
and uncomfortable. This inflammation causes an increased
sensitivity to allergens and a host of other asthma triggers
like exercise, medications, stress, pollution, humidity and even
laughter.
The symptoms of asthma vary from person to person; early morning
or late night coughing, wheezing, chest tightness, fatigue,
anxiety and shortness of breath are all common. Allergen induced
asthma usually becomes apparent before the age of 35.
Non-allergic asthma usually has its onset in middle age and can
be triggered or worsened by reflux disease, exercise, weather
changes and illness.
Research is underway in several key directions, and on a global
scale, to find more effective treatments and possibly even a
cure for asthma. Secondary intervention studies, risk
assessment, environmental intervention and assessing allergen
exposures all allow researchers to explore different treatment
options to deal with the symptoms of those who already have
asthma. Studying the genetics and hereditary components of the
disease, and the pathogenesis and mechanics, may someday lead to
a cure.
Research progress is dependant on funding, and the participation
of those who have or are at risk of developing asthma either
through lifestyle or genetics. Funding for research comes from
many sources: private companies and foundations, private
citizens, corporate donations and government grants - but money
is often scarce; and with so many important and deserving
projects, the competition for gaining the needed funding can be
fierce.
Great strides have been made in the area of asthma, but the
steady rise in new cases suggests that greater strides are
necessary. Researchers all over the world are working hard to
develop new treatment modalities and possibly even a cure for
this chronic and often debilitating disease.
