Losing
Their Punch
As
doctors continue to over-prescribe antibiotics in China, a Tufts
expert says the country's population may soon find that the once-powerful
drugs don't work.
Boston
[04.26.02] -- Used by Chinese
doctors to treat everything from runny noses to tuberculosis,
antibiotics have grown increasingly popular within the country's
medical community because they are cheap and effective. But that
may soon change, says a Tufts expert, who warns that overuse in
China and around the world may be causing the drugs to lose their
punch.
"Antibiotics
save countless lives by killing bacteria, the cause of infections
and deadly illness," reported the Los Angeles Times. "But
the more these drugs are used, the greater change of a genetic
mutation that allows bacteria to protect themselves. Drug-resistant
strains then flourish as antibiotics kill off other bacteria that
compete for food."
Costing
patients just a few pennies, the drugs have helped dramatically
improve healthcare for millions in China -- but not without a
cost. Studies now show that the drugs have contributed to a new
wave of drug-resistant diseases that are spreading around the
country.
The
problem is not isolated to China, says Tufts' Dr.
Stuart Levy -- a professor
of medicine at Tufts and one of the nation's leading experts
on antibiotic resistance. But with a population of 1.2 billion,
it poses a particular challenge.
"China
is among the leading countries that are a concern," he told the
Times. "The situation is terrible because these drugs are
essentially available over the counter."
According
to the newspaper, "More than 70 percent of drug prescriptions
nationwide in China are for antibiotics, compared with about 30
percent in the West."
Farmers
heavily use antibiotics on their livestock as well -- a practice
that has been shown to help breed resistant bacteria -- further
adding to China's antibiotic resistance problems.
But
few people in the region are aware of the possible dangers of
overusing the powerful drugs.
"Experts
say Chinese health workers have only rudimentary medical training
and often don't know the dangers of overuse of drugs," reported
the Times. "Health workers say they are only beginning
to be made aware of the problem, and few government policies exist
to curtail antibiotic use."
Though
more aware of the problem, doctors in the United States are facing
similar problems.
In
a Wall Street Journal article published on Thursday, Levy
warned, "Strains of five bacterial species capable of causing
life-threatening illnesses already evade every antibiotic in the
clinician's armamentarium."
And
the Food and Drug Administration has found that over 70 percent
of the infection-causing bacteria in hospitals is resistant to
at least one of the drugs most commonly used to treat it, reported
the Augusta Chronicle.
Levy
-- who heads the Alliance
for the Prudent Use of Antibiotics -- says resistance is becoming
increasingly more widespread.
"It's
not simply, 'Oh, it's resistant to this. It's resistant to two,
three, four, sometimes eight or nine drugs," he told the Chronicle.
"While the worst ones are seen in hospitals, there are some pretty
nasty ones [in the general population]."
For
now, scientists and doctors are hoping that educational campaigns
will help curb the problem. But more needs to be done.
"So
in quiet conversations, scientists and economists are beginning
to think about stronger medicine," reported the Journal.
