RESISTING DRUGS, TB SPREADS FAST IN THE WEALTHY WESTERN NATIONS|

AMSTERDAM, Netherlands Deadly strains of drug-resistant
tuberculosis are increasing not just in poor
countries but in wealthy Western ones, according to a new report from the World Health Organization and other groups.
The report, to be released Friday at a tuberculosis
conference in Amsterdam, says drug-resistant cases have recently increased by 50 percent in Denmark
and Germany. While the total number of cases was small, and
most of those analyzed were resistant to only
one of the five most common drugs, doctors at
the conference say the trend is alarming. Its a message Watch out guys, this is
serious, said Dr. Marcos Espinal,
the lead author of the report. Its a potential major crisis in
the future.
In other parts of the globe, from China to Siberia to
Puerto Rico, strains resistant to at least
four of the five common drugs have emerged. Some cases are fatal; others are curable only at 100 times the cost of standard TB
treatment. In Western Europe or the United States, where some
cases of multiple-drug-resistant tuberculosis
surfaced earlier, the cost of curing one
can be as high as $250,000, counting $10,000 worth of drugs
plus lengthy hospitalization, lab work,
outpatient care and possible lung surgery.
Tuberculosis, one of the worlds leading killers during the
18th and 19th centuries when it was called
consumption, was nearly conquered after World War
II by the discovery of antibiotics. But in the last decade, largely because of AIDS, it has re-emerged as one of the worlds most devastating
diseases.
Eight million people are newly infected each year, and 2
million people die. Unlike malaria, which follows mosquito vectors, or AIDS, which spreads by
sexual or blood contact, TB can circle the world at the speed
of a passenger jet and be transmitted by a
single cough. Health officials are seeking $700 million to attack the disease in poor countries. They are in the awkward position of trying to raise the alarm in rich
countries that dont feel very threatened. At present,
tuberculosis usually remains dormant in
healthy people; only about 2 percent of them will progress toward the telltale sign
coughing up blood. Most cases in America and Western Europe occur among poor recent immigrants, or among AIDS patients,
cancer patients, drug addicts and others with suppressed immune
systems. The United States recently
doubled foreign aid grants for TB control, to $22
million. It also spends $100 million a year overseas to fight
AIDS, a major underlying factor.
But the international medical communitys most
powerful weapon for raising money is the fear
that an explosion of cases in the Third World will let divergent strains merge into something incurable and highly contagious that
will attack the West.
Warnings have already been sounded: In the early 1990s, a
multiple-drug-resistant strain killed about 500 people in New
York City most AIDS-infected and
cost $1 billion to suppress. In 1997 a rural area on the Kentucky-Tennessee border fell prey to a contagious, rapidly growing
strain that, luckily, succumbed quickly to standard drugs.
The emergence of drug-resistant strains in Germany and
Denmark is seen as another possible harbinger
of a Western epidemic echoing the one sweeping
through Africa and Asia. Denmark has had only about 500 TB
cases; they were analyzed for resistance to
standard antibiotics and were generally found not to resist more than one strain. Germany has had 10,000 cases, but fewer than
2,000 were analyzed. What surprised experts was that a small
problem had grown by 50 percent in three
years.
In each country, about a third of the cases were among
native-born Danes and Germans; two-thirds were among immigrants, most from Eastern Europe, a few
from Africa. Tuberculosis
experts fear a backlash against immigration but say that would be a mistake.
People have this notion that you can wall off
your borders from germs, said
Kraig Klaudt, a spokesman for the World Health Organization. You
cant. Espinal said, No screening tools we have will catch the whole
problem in refugees, tourists, workers and
everyone else. His solution: to help those countries where the situation is so terrible.
The report on multiple drug resistance being released
Friday, International TB Day, does not cover
the whole world, but 72 geographical settings
sometimes a whole country, sometimes just a province
with about 68,000 patients whose sputum
samples were tested in sophisticated medical
laboratories. Researchers
found nine particularly worrying hot spots places where
more than 3 percent of patients seeking treatment for the first
time already had drug-resistant tuberculosis.
The nine were in seven countries: Estonia, Latvia,
Russia, China, India, Iran and Mozambique.
