Respiratory Diseases

 

For decades, departmental researchers have sampled, measured, and extrapolated pollutants from the air. New techniques are bringing them closer to understanding how air pollution causes serious—sometimes fatal—effects in people with lung disease. This issue of Environmental Health News describes several projects affiliated with the Northwest Center for Particulate Air Pollution and Health (NW PM Center), funded by the Environmental Protection Agency and housed in our department. We also describe findings related to Parkinson’s disease, and celebrate the accomplishments of our faculty, staff, and students as the 2002­2003 academic year comes to a close. Air pollution is implicated in 50,000 premature deaths and costs an estimated $40 to $50 billion in health-related costs annually in the United States. Lung disease is the nation’s number-three killer, responsible for one in seven deaths. While air pollution extracts costs from everyone, certain groups are more susceptible than others. Research in the department has focused on asthmatic.

VULNERABLE POPULATIONS

It has long been accepted that people with respiratory disease are more at risk from air pollution than others, but a recent study of cystic fibrosis patients provides the first specific evidence of this, according to department Chair Dave Kalman. Dr. Joel Kaufman of the Occupational and Environmental Medicine Program was principal investigator. His study represents the first time that a genetic disease has been shown to be significantly affected by environmental pollutants, Kalman said.
Cystic fibrosis is a genetic disease affecting about 30,000 children and adults in the United States. A defective gene causes the body to produce an abnormally thick, sticky mucus that clogs the lungs and leads to life-threatening infections. The disease worsens over time and, even with advances in testing and research, limits life expectancy to about 30 years.
Dr. Kaufman’s study began with a premise that levels of air pollution—even those that fall within current air quality standards—can cause adverse health effects for people with chronic respiratory diseases. Cystic fibrosis interested him because no previous research had been done and because a national registry provides data on pulmonary exacerbations (times when the lung disease requires hospitalization or intervention with antibiotics), pulmonary function, and mortality.
Dr. Kaufman’s team included Stacey Newsom, a physician who received her Master of Public Health degree from our department last year, and Chris Goss, assistant professor in pulmonary and critical care medicine.
Their epidemiologic study examined the association between ambient air pollution, collected in the Environ-mental Protection Agency’s Aerometric Information Retrieval System (AIRS) database, and pulmonary-specific outcomes recorded in the National Cystic Fibrosis Patient Registry. They were able to match 19,000 subjects, by ZIP code, with air pollution data for particulate matter, ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide.
This first study shows an association between particulate matter and worsening of cystic fibrosis, said Dr. Goss, who presented a paper on the study at the North American Cystic Fibrosis meeting.

Hippocrates & Asthma

 

Hippocrates, the “father of medicine,” first used the medical term “asthma,” which means to breathe hard or to pant.

Records of asthma-like conditions go back to the dawn of writing itself. A condition like asthma was described in the Ebers papyrus from ancient Egypt in 1550 BC, the time of the building of the pyramids. It contains prescriptions written in hieroglyphics, including a remedy prepared as a mixture of herbs heated on a brick so that the sufferer could inhale their fumes.

Hippocrates (460–357 BC) described the disease and recognized its spasmodic nature. He believed its onset to be caused by moisture, occupation, and climate. His recommended treatments included induced vomiting, purging, and bleeding.

A few centuries later, Galen, the famous Roman physician, determined that asthma was due to an obstruction of the bronchial tubes. One of his prescribed treatments was owl’s blood in wine. In his book De Morbis Artificium Diatriba, published in 1700, Ramazzini described occupational asthma in gilders, tinsmiths, glassworkers, tanners, bakers, millers, stonecutters, wool carders, and other workers. He recommended butter, milk, emulsions of almonds and of melon seeds, and avoidance of anything that might dry the air passages.

Tobacco was, amazingly, recommended in the 16th century for asthma. Until the 20th century, smoke remained an accepted way to deliver asthma medications to the lungs.

Sir Henry Salter, a Victorian doctor, recommended strong black coffee. This may have had some scientific basis: caffeine is related to theophylline, recognized today as an effective asthma medicine

A Noninvasive Test

A noninvasive test for respiratory distress could be as simple as blowing up a child’s party balloon.

The balloons—the common Mylar type sold in wholesale florist supply stores—provide a novel way of collecting exhaled nitric oxide. The body creates nitric oxide as an immune response when airway linings are exposed to an allergen or toxin—for example, during an asthma attack, said Jane Koenig, director of the EPA Northwest Center for Particulate Air Pollution and Health based in our department. Exhaled breath is a better indicator of airway inflammation than a blood or urine test, which could pick up inflammation from elsewhere in the body.

Koenig’s team, which included graduate student Carrie Fields, applied a biomarker (a biochemical response that indicates changes in a biological system) to air pollution for the first time. “Exhaled nitric oxide is a good, noninvasive measurement, one that a doctor or clinician could be equipped to use,” Fields said.

Mylar doesn’t react chemically, which makes balloons an ideal vehicle for transporting exhaled air from the field to the laboratory for analysis.

The balloons were just one of many tools; Fields also measured pulse rate, blood pressure, and lung function. Her 16 subjects—older people with asthma or chronic obstructive pulmonary disease—were asked to wear nearly five pounds of monitoring equipment for almost two weeks.

Observations involved a daily visit to the subjects’ homes to collect health data and indoor, outdoor, and personal air pollution measurements. Subjects kept diaries of symptoms and smoky activities such as cooking, which were correlated with other data. The study period—the winter of 2002–2003—had an unusual number of burn bans. “This happened to be a bad year for the health of folks with respiratory disease, but a good year for us,” Fields said.

Her study found a correlation between outdoor air and personal air pollution (the dust cloud that surrounds everybody) and exhaled nitric oxide. That finding didn’t correlate with indoor air, though analysis is continuing. The next phase of the study will look at sources of air pollution.

The association between pollutant levels and exhaled nitric oxide turned out to be stronger than those found with blood pressure, oxygen saturation, or pulse rate, giving Koenig encouragement for the future. “I’ve used a lot of tools in my time to explore airway inflammation,” she said, “and this certainly has been the easiest. It also seems like one of the most promising.”

Thoracic Society

The American Thoracic Society (ATS) met in Seattle in May, giving researchers from the EPA-funded Northwest Center for Particulate Air Pollution and Health (NW PM Center) an opportunity to meet with colleagues from around the world. Jane Koenig, Joel Kaufman, Jeff Sullivan, Dan Luchtel, Tim Takaro, Carol Trenga, Karen Jansen, Therese Mar, and Coralie Baker attended. Mar’s poster on stagnant air and mortality in Seattle was highlighted in the ATS Daily Bulletin.

An afternoon session, hosted by the NW PM Center, discussed differences in findings between studies done in Boston and Seattle. The Boston study found a strong association between onset of myocardial infarction (heart attacks) and small particulate matter (PM2.5), while the Seattle study found no association. It’s possible the chemical composition of particles differs in the two cities, Koenig said. The joint working group developed a list of collaborative analyses that may shed light on these discrepancies.
At the meeting, Joel Kaufman chaired a scientific session on occupational lung disease.

Clean Air Priorities

Departmental staff and faculty joined others in the region at the Northwest Air Pollution Summit in early June. The three-day collaborative exercise produced a list of proposed projects, including retrofitting old diesel engines, working toward reducing residential wood burning and agricultural burning, writing curricula on air quality for elementary schools, reducing asthma triggers in tribal communities, and tackling air toxics. These projects are a step toward selecting five air quality priorities.

Tim Larson, Tim Gould, Joellen Lewtas, and Jane Koenig of the NW PM Center participated in the summit, sponsored by the Environmental Protection Agency’s Northwest Collaborative Air Priorities Project (NW-CAPP).

The summit brought about 200 stakeholders together for three days to devise a list of priorities to improve air quality in the Pacific Northwest over the next five to ten years.

“This type of collaboration is unprecedented in addressing air pollution concerns,” said Jon Iani, Administrator of EPA’s regional office in Seattle. “This event moves us toward a shared vision. It’s encouraging to see so many groups coming together to recognize common goals and work towards sustainable solutions.”

Wood smoke in the air

Bethany Katz, MS, Environmental Health (Kalman), measured the proportion of atmospheric fine particulate matter attributable to the combustion of wood. Since 1997, the National Ambient Air Quality Standard has required determination of the sources of fine (less than 2.5 microns in diameter) particulate matter. Previous interpretations of Seattle’s ambient air quality data offered varying proportions for diesel emissions and wood smoke. This discrepancy can affect risk assessments, epidemiologic studies, and control strategies, which rely on an accurate assessment of the sources and composition of particulate matter. Katz incorporated source-specific chemical tracers for wood smoke, specifically levoglucosan, a polar organic compound produced by biomass combustion, to better determine the proportions.

A new test for hearing loss

Thomas Olenchock, MS, Industrial Hygiene (Seixas), worked with a new tool for measuring preclinical hearing loss from occupational noise exposure. This new method measures tiny sound distortions generated within the ear’s cochlea. This study was designed to further evaluate the relationship between work-shift noise exposure and hearing damage. Olenchock tested 22 construction workers from six trades before and after a work shift. He found a greater loss in hearing function with higher noise exposure as measured by both audiometry and the new method. Using the new test, Olenchock found that the two hours of noise exposure immediately before testing was the most predictive of changes in hearing function.

Predicting injury outcomes

Marilyn Nayan, MD, MPH candidate, Occupational and Environmental Medicine (Franklin), developed predictors of outcome for surgically and nonsurgically treated work-related cubital tunnel syndrome. Cubital tunnel syndrome, also called ulnar neuropathy at the elbow (UNE), causes numbness and tingling of the ring and small fingers, and pain in the elbow or forearm. Despite its frequent occurrence, several aspects of its diagnosis and treatment remain controversial. Dr. Nayan studied demographic, socioeconomic, clinical, and diagnostic characteristics of workers within Washington state’s workers’ compensation system diagnosed with cubital tunnel syndrome; determined the association of these characteristics to surgical and nonsurgical outcomes; and assessed clinical predictors of outcome. The data analysis is in progress.

Mercury affects the brain

Craig Tin, MS candidate, Toxicology (Faustman), explored how methylmercury exposure can induce toxicity by inhibiting cell cycle progression. Using cell cultures of p53 transgenic mouse embryonal fibroblasts, Tin examined the effect of p53 status on gene expression, with a focus on genes associated with the cell cycle. Accumulation of cells in the G2M phase of the cell cycle in response to methylmercury was associated with a p53-dependence. In addition to the expected changes in gene expression, he identified several unknown effectors downstream of p53 for possible roles in differential sensitivity.

Iron, Manganese & Parkinson's

Departmental researchers have found that high consumption of iron and manganese can increase the risk of getting Parkinson’s disease. The study, which appeared in the June 10 issue of Neurology, found that people whose diets are high in both manganese and iron are 1.9 times more likely to be Parkinson’s patients than those with lower levels. People with diets high in iron who take one or more multivitamins a day are 2.1 times more likely to develop Parkinson’s disease.

Researchers aren’t suggesting that people change their diets, but that they should follow the labeled directions on dietary supplements. “We had people in this study taking more than one multivitamin a day,” said co-author Karen Powers. “That’s not a good idea. If the directions say ‘take one vitamin a day,’ that really means, ‘take one vitamin a day.’”
Authors include Powers, Harvey Checkoway, Gary Franklin, and Terri Smith-Weller of the DEOHS, and W. T. Longstreth Jr. and Phillip D. Swanson of the UW School of Medicine. The research was supported by grants from the National Institute of Environmental Health Sciences.
