XDR TB
Extensive (or Extreme) Drug Resistant TB
XDR TB extensive (or extreme) drug resistant TB
• MDR TB - defined as TB resistant to at least the 2
most potent anti-TB drugs, isoniazid and rifampicin
(first-line drugs)
• XDR TB* - defined as MDR TB that is also resistant
to at least 3 of the 6 classes of second-line drugs
*Definition may change based upon recommendations
of expert panel

TB elimination, said emergence of a super-resistant
strain is a potent reminder that tuberculosis remains
a formidable threat. "It is widely distributed
geographically, including in the United States, and
renders patients virtually untreatable," Castro said.
Dr. Marcos Espinal, executive secretary of WHO's
TB elimination program, called XDR TB a veritable
death sentence. "If people are failing first- and
second-line drugs and we don't have in the pipeline
a new drug for immediate use, that's a crisis," he
said.
Media Response to XDR TB

WHO expresses concern
WHO background briefing note
issued prior to XDR-TB Expert
Consultation meeting in South
Africa
'Virtually untreatable' TB
found
A "virtually untreatable" form of TB has emerged,
according to the World Health Organization
(WHO).
Extreme drug resistant TB (XDR TB) has been seen
worldwide, including in the US, Eastern Europe and
Africa, although Western Europe has had no cases.
Dr Paul Nunn, from the WHO, said a failure to correctly
implement treatment strategies was to blame.

Coverage in major weekly journals
Newsweek Sept. 13, 2006 –
WHO recently issued a warning
that deadly new strains of
tuberculosis appear to be
spreading around the globe…
HIV sufferers are particularly
vulnerable because of their
weakened immune systems.
TB, already the world’s fourth
most fatal infectious disease,
could wreak havoc with AIDS
treatment programs

The extreme drug-resistant

health experts said in
Johannesburg on Thursday.
"There is no time to wait before

said the World Health

Jaramillo, explaining that an
epidemic could have a deadly

Editorial in New York Times & Int. Herald Tribune
EXTREME TUBERCULOSIS
SEPTEMBER 14, 2006
TB is outrunning us. In the last few months, 53 patients in the South
African province of KwaZulu-Natal were found to have a form of the
disease resistant to enough existing drugs that it is virtually incurable. All
but one of those patients have died…
Stinginess created this problem. Generosity is needed to fix it.
Stop TB XDR Response
1. Coordination – Develop an appropriate,
coordinated global response to XDR TB
2. Resource mobilization – Raise sufficient funds to
ensure no delays in the global response to XDR
TB
3. Case definitions – Ensure consistency in
surveillance and case management
4. Monitoring and evaluation – Determine
geographical and temporal spread of XDR TB
Stop TB XDR Response (2)
5. Communications – Provide a proactive flow of
information to all stakeholders, including member
states and the global media
6. Case management – Define the optimal way of
rapidly identifying suspect XDR cases and ensuring
appropriate treatment; determine appropriate
infection control measures in health facilities
7. Country support – Ensure a timely and sufficient
response to requests from countries for assistance
This time, I bet you that if the press is
prompted and well prepared, journalists will
come like flies around a cake and other
objects...
