An unknown number of lung transplant patients who have had bronchoscopies
since June 1, 2001 at Johns Hopkins Hospital may have
received a potentially fatal lung infection from a defective medical
instrument.
Hospital officials
told The Baltimore Sun that some patients examined by one of three
contaminated bronchoscopes have died after being infected with
the bacterium pseudomonas, but that they do not yet know if they
died from the bacteria or from their existing illness.
The hospital said it
had sent certified letters to 415 lung transplant recipients,
and patients suffering from cystic fibrosis, lung cancer of AIDS,
warning them to contact their doctors if they experience symptoms
including fever, coughing, phlegm or shortness of breath.
Hospital officials
said they discovered the problem after realizing that 128 patients
had been infected with pseudomonas -- a number 200 to 300 percent
higher than would have been expected. Two of the patients have
died, according to hospital officials.
"Although
it's not possible to know whether you are now at increased risk,
it is important you be alert to any sign of infection ...," the
letter said.
The bronchoscopes
-- a tiny instrument with a camera on one end used to inspect
a patient's lungs and take tissue samples -- are made by Olympus
America, which described the defective instruments as having a
loose valve that trapped bacteria.
Dr. William
Jarvis of the Centers for Disease Control and Prevention said
Olympus learned of the problem in September, but did not start
sending recall letters to hospitals that used the defective devices
until November.
The company
didn't inform the Food and Drug Administration of the defect until
December, Jarvis added. He said he was "perplexed" that
neither the FDA or Olympus posted the recall notice on their Web
sites.
Other medical
centers that used the Olympus America bronchoscope are reported
now checking their medical charts to see if they may have a problem
similar to the one at Johns Hopkins.
"We don't
know
what the magnitude of the problem is yet," said Dr. Daniel B.
Jernigan, a medical epidemiologist with the CDC.
