Alert Against Drug-resistant Tuberculosis

In Europe multidrug-resistant tuberculosis is spreading at an alarming rate, warns WHO.

The WHO hopes its action plan, published Wednesday, will prevent 263,000 cases of multidrug-resistant tuberculosis (MDR-TB) and the more lethal extensively drug-resistant TB (XDR-TB) between 2011 and 2015.

Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the lung. It may spread to other organs.

"TB is an old disease that never went away," said Zsuzsanna Jakab, WHO regional director for Europe.

"Now it is evolving with a vengeance and we have to find new weapons to fight it," she added, before promising technical support for any member nations who committed to the plan.

More than 80,000 new cases of the lung disease are reported each year in Western Europe, London being the hardest hit capital city with 3,500 new cases diagnosed annually.

Screening Tests for Tuberculosis
Tuberculin skin test and Interferon – Release Assays are tests used to screen for tuberculosis.

Ibrahim Abubakar, a TB expert at Britain's Health Protection Agency (HPA), called on health officials to take the lead in the fight against the condition.

"I think without a doubt there's a need to make all healthcare workers, but GPs (general doctors) and A&E staff in particular, aware of the signs and symptoms of TB so they can recognise this earlier," he said.

The Lungs
The lungs are our organs of respiration. It is within these, that exchange of gases takes place.

Almost 12 percent of newly diagnosed TB patients have the MDR form. Half of those sufferers are expected to die as drugs strong enough to treat the disease are unavailable, and are not expected online before 2013.

MDR-TB and XDR-TB fail to respond to standard anti-tuberculosis drugs, making them much more complex and costly to treat and increasing the threat that TB will spread much more widely, especially in poorer environments where it thrives.

Rising immigration from infected areas has contributed to the rise of TB in Europe, but the WHO warned against complacency among the native populations.

"It can affect anyone," Ogtay Gozalov, from the WHO European regional office, said. "Any one of us can be exposed to these diseases and get infected.

"A big proportion of these people who are infected can convert and develop the (resistant) disease," he cautioned.

Meanwhile, a mobile X-ray unit which can detect the disease has proved a cost-effective success in London, it was to be announced at the HPA annual conference at the University of Warwick in central England on Wednesday.

The "find and treat" service visits locations where there is a high risk of infection -- including drug treatment services, hostels and homeless centres -- and tests individuals on a voluntary basis.

If the disease is detected, the patient is then shadowed by health officials for the duration of their six month treatment.

"With TB numbers remaining high in London, the 'find and treat' programme was identified as a potential method of tackling the problem in these high risk populations," said HPA study author Peter White.

"It has proved to be successful in identifying and offering treatment to those unaware they were infected," he added.
