TB rates down, but its "global burden" remains huge: WHO

WASHINGTON: The fight against tuberculosis is making progress but "the global burden" of the deadly disease remains enormous, the World Health Organization said in its annual report Wednesday.

The WHO has pledged to cut TB deaths to half the 1990 rate, a goal the agency said it was on track to achieve. And the number of new cases per capita was falling as well -- down 2.2 percent last year from 2010 and the year before.

The WHO also hailed innovations in diagnostics to detect the lung disease as well as the new drugs and new vaccine possibilities advancing through development stages.

But tuberculosis still sickened 8.7 million people around the world, killing 1.4 million of them, according to the 2012 report. And in Africa and Europe, mortality rates are not showing the declines seen elsewhere, and may not achieve the 50 percent drop by 2015.

Asia remained the hardest hit region, with nearly 60 percent of the TB cases detected last year -- two-thirds of which were detected in China and India.

A half million children under age 15 contracted TB and 64,000 died last year, the first time the WHO specified figures for children.

Perhaps most worryingly, identifying and treating multi-drug-resistant tuberculosis -- around four percent of new cases and 20 percent of previously treated cases -- remains hugely challenging.

Around the world, of those estimated to have the strains resistant to standard medications, only about one in five were notified. In China and India, that figure was even worse: fewer than one in 10 drug resistant cases were detected.

"Major efforts are needed to improve treatment success rates among patients" with the drug-resistant strains of TB, the WHO said.

Medical aid group Medicins sans Frontiers concurred, with TB advisor Grania Brigden saying the newest report "reinforces that multidrug-resistant tuberculosis is an escalating public health emergency."

"Yet the global response is abysmal, with levels of testing and treatment remaining shockingly low," Brigden said, with only one in 20 patients tested. Even when diagnosed, she added, the survival rate is less than 50 percent.

"We continue to struggle every day with inadequate tools and drugs to tackle the disease," which is increasing in prevalence in the places they work, she said.

But Brigden said the good news is the new TB drugs "on the horizon for the first time in nearly half a century."

Medical journal "The Lancet" was similarly disheartened, arguing in an editorial published to coincide with the WHO report that "insufficient attention and funding over several decades have allowed the global epidemic to remain a deep scar on the reputation of global health."

"The existing control approach has taken a short-term view with heavy reliance on treatment and cure, but the health systems of many countries have simply been ill-equipped to deal with the complexities of managing tuberculosis, a fact proven by the escalating rates of multidrug-resistant and extensively drug-resistant strains of TB," it continued.

While recognizing shortfalls, the WHO was nevertheless positive about the TB battle.

"In the space of 17 years, 51 million people have been successfully treated and cared for according to WHO recommendations. Without that treatment, 20 million people would have died," Mario Raviglione, director of the WHO Stop TB department, said in a press release.

"This milestone reflects the commitment of governments to transform the fight against TB."

But the WHO said more money is needed for continued and improved progress to treat and control TB outbreaks, saying it is $3 billion short of the $8 billion necessary. And an additional $1.4 billion is required for research and development to reach the necessary $2 billion.

40m more TB deaths due to smoking

Posted: 05 October 2011

PARIS: Lung damage caused by smoking could cause an additional 18 million cases of tuberculosis and 40 million extra deaths from TB by 2050, according to a study published on Tuesday in the British Medical Journal (BMJ).

The estimates derive from a mathematic model of smoking trends and smoking's impact on TB risk.

Africa, the eastern Mediterranean and Southeast Asia will see the biggest rise in smoking-linked TB, the study says.

"Aggressively lowering the prevalence of tobacco smoking could reduce smoking-attributable deaths from tuberculosis by 27 million by 2050," according to the paper, headed by Sanjay Basu of the University of California at San Francisco.

WHO urges stepped up battle against TB

Posted: 24 March 2011

A patient receives a tuberculosis test
GENEVA: The World Health Organisation on Wednesday urged donors to stamp out multidrug-resistant tuberculosis after the number of the hard-to-treat strains of the lung disease doubled in recent years.

In a progress report to mark World TB Day on Thursday, the WHO and partner agencies estimated that the number of new cases of MDR tuberculosis would reach two million between 2011 and 2015 if it is left unchecked.

"MDR-TB is a threat to all countries as it is difficult and expensive to treat," said Michel Kazatchkine, executive director of the Global Fund to Fights AIDS, Tuberculosis and Malaria.

"Unless we make an extraordinary effort to tackle this problem our ability to finance and secure continued progress against TB in general will be threatened," he added in a statement.

The WHO estimated that $900 million would be needed over the next four years to reach the target of treating one million people with such strains.

Some 50,000 people are currently receiving treatment.

In 2009, 9.4 million people became ill with all types of tuberculosis and 1.7 million died of the disease, according to the WHO.

An estimated 440,000 cases of MDR-TB occurred in 2008, the last year for which data was available, including 150,000 deaths.

"Despite all the progress that has been made, the response is far from sufficient," warned Mario Raviglione, head of the UN health agency's Stop TB campaign.

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

Rifat Atun of the Global Fund said the number of resistant strains "has doubled in recent years" and were continuing to progress.

TB patients face higher lung cancer risk, say researchers

Posted: 05 January 2011

TAIPEI - Tuberculosis patients are 11 times more likely than the average to develop lung cancer, according to a new study published by a group of Taiwanese scientists.

The researchers followed more than 700,000 randomly selected individuals over a period of six years, including 4,480 diagnosed with tuberculosis, they said in a statement Wednesday.

"The incidence of lung cancer in these tuberculosis patients was 11 times greater than people without tuberculosis," said one of the researchers, Chen Chih-yi, from China Medical University in the central Taiwan city of Taichung.

"This study suggests that it is also important to watch out for lung cancer prevention in the campaign against tuberculosis."

The findings, published in the January issue of the Journal of Thoracic Oncology, support the notion of a link between tuberculosis and lung cancer, which has so far been suspected but not definitively proved.

"Tuberculosis is a very common chronic disease worldwide. People in developing and undeveloped areas suffer from it mostly," said Chen.

"It is well known that lung cancer is causally associated with smoking. Less attention has been focused on whether people with tuberculosis are also at higher risk of developing lung cancer."

WHO unveils radical new TB diagnosis machine

GENEVA - The World Health Organisation on Wednesday unveiled a new "while you wait" test for tuberculosis, that radically cuts down the testing time and detects drug resistant forms of the deadly lung disease.

The desktop computer-sized automated test machine produces results in 100 minutes instead of up to six weeks of laboratory testing for the TB bacteria, which infects about one-third of the world's population, according to the UN health agency.

The machine analyses a sample of the patient's spittle.

"What we are doing today at WHO is to endorse the use by countries of a new fully automated rapid test that detects quickly in one hour and 40 minutes tuberculosis and the most difficult forms of tuberculoses," said Mario Raviglione, head of the WHO's Stop TB programme.

"This test will transform and revolutionize the way we handle TB care and control," he added.

Raviglione underlined that it could detect hard to treat drug resistant forms and TB associated with HIV/AIDS.

Half a million HIV positive people die from TB each year, a quarter of all AIDS deaths, according to UNAIDS.

The WHO has high hopes of improving detection in developing countries, the hardest hit areas.

The number of cases of tuberculosis in the world stabilised last year, with 9.4 million new infections. About 1.7 million people died.

The UN health agency is trying to cut the death rate by half by 2015. It has warned that progress against the disease is far too slow.
