May 9, 2007 (AP) —Rescue workers and firefighters contracted
a serious lung-scarring disease called sarcoidosis at a much higher
rate after the Sept. 11 attacks than before, said a study that
is the first to link the disease to exposure to toxic dust at Ground
Zero.
The study, published by nine doctors including the medical officer monitoring
city firefighters, Dr. David Prezant, found that firefighters and rescue workers
contracted sarcoidosis in the year after Sept. 11, 2001, at a rate more than
five times higher than the years before the attacks.
Sarcoidosis, which can be life-threatening, causes an inflammation in the lungs
that deposits tiny cells in the organs, leaving damaging scar tissues. Some rescue
workers and others who were exposed to the dust cloud that enveloped lower Manhattan
after the World Trade Center collapsed say they contracted the disease from their
work at Ground Zero.
The study compared the rates of contracting sarcoidosis among fire department
employees for 15 years before Sept. 11 and for five years after it. It said firefighters
who showed symptoms of the disease on chest X-rays underwent more intensive exams.
After the trade center attack, 26 firefighters were diagnosed with sarcoidosis,
the study found. Thirteen were diagnosed in the first year after the attacks,
which represents a rate of 86 per 100,000. In the 15 years before the attack,
the rate of sarcoidosis was 15 per 100,000, the study found.
None of the 26 rescue workers, who are in their 30s and 40s, has died of the
disease, and about 10 have improved or recovered since their diagnoses, the study
found. Two of the firefighters were former smokers, the study found.
Dr. Jacqueline Moline, who directs the largest monitoring program for Ground
Zero workers, which has screened more than 20,000 people at Mount Sinai Medical
Center, said several patients in her program have been diagnosed with sarcoidosis.
Mount Sinai plans to publish its own research in the next few months on the rate
associated with Ground Zero work. Last fall, it published a study concluding
that 70 percent of Ground Zero workers suffered from different respiratory illnesses
after the attacks.
"We're all looking to see various diseases that might develop as a result
of 9/11 exposure," Moline said. "We have to be vigilant."
The study was published this week in the May issue of CHEST Physician, a journal
published by the American College of Chest Physicians.
