 WHO: World must fight drug-resistant TB threat

wpe8.jpg (10585 bytes)BEIJING – The Gates Foundation is funding tests of new treatments for tuberculosis patients in China , part of a critical worldwide effort to stanch emerging, hard-to-cure strains of the disease that the World Health Organization says are like a time bomb.

One of the world's oldest and deadliest infectious diseases, TB has mutated into hardier forms that withstand some of the most commonly used medicines. Left unchecked, people with drug-resistant TB could spread the disease to others, creating a widespread epidemic in the highly mobile global economy.

At a meeting of health ministers in Beijing, software magnate Bill Gates' foundation and the Chinese government announced a $33 million project that initially covers 20 million people in six provinces and will be expanded to 100 million people over five years.

New approaches being tried include tests that diagnose drug-resistant TB in hours instead of weeks and drug combinations that at least halve the number of pills patients have to take. Mobile phone text messages will be used to track patients and their treatments.

WHO Director-General Margaret Chan told health ministers and senior officials from 27 countries worst-affected by the new drug-resistant strains of TB that they must make dramatic improvements in detecting infections and build stronger health care systems.

"Call it what you may — a time bomb or a powder keg," Chan said at the opening of a three-day meeting on drug-resistant TB in Beijing . "Any way you look at it, this is a potentially explosive situation."

Countries attending the meeting said Wednesday they would draw up national plans to provide drug-resistant TB patients with access to treatment by 2015, ensure a sufficient supply of anti-TB drugs, better train health workers and other measures aimed at controlling the spread of drug-resistant strains.

The disease is caused by germs that spread when a person with active TB coughs, sneezes or speaks. It's ancient and treatable but now has evolved into stronger forms: multidrug-resistant TB, which does not respond to two top drugs, and extensively drug-resistant TB, which is virtually untreatable.

The problem has been partly blamed on health care systems that lose track of patients who do not complete their courses of treatment, allowing the TB bacteria to develop resistance to normally potent medicines.

In 2007, 1.75 million people died of tuberculosis. Of the more than 9 million people around the world who contract the disease every year, about 500,000 get multi-drug resistant TB. The WHO estimates that 150,000 people die of drug-resistant TB every year worldwide.

Nearly a quarter of those who contract the drug-resistant strains are in China , where legions of rural migrants face an inadequate health care system.

It is also a problem in India , where rural health care is often poor and there is little control over the sale of anti-TB drugs; Russia , which faces a shortage of qualified medical staff and drugs; and South Africa , where the disease thrives amid an AIDS epidemic that has weakened the immune systems of people with HIV.

The Bill & Melinda Gates Foundation chose to fund the TB project in China because the disease is such a large problem on the mainland and the foundation hopes any success in tackling it there will likely help push new approaches elsewhere.

"Because of its skill, its scale, its TB burden, its love of innovation, and its political commitment to public health, China is a perfect laboratory for large-scale testing of new tools and delivery techniques to fight TB," Gates said at a news conference.

Medecins Sans Frontieres, also known as Doctors Without Borders, welcomed the Gates project but said China should not neglect other drug-resistant TB sufferers in the country who are not covered by the program.

"It's a big pilot project but the question is what happens to all the other patients who need treatment now and what will be provided to them while this project is ongoing in the next five years," said MSF's Tido von Schoen-Angerer.

TB is usually treated in six months with a $20 cocktail of four antibiotics, but its drug-resistant form takes up to two years and is at least 100 times more expensive to fight.

 

Hard-to-cure TB poses new global health threat

By GILLIAN WONG, Associated Press Writer Gillian Wong, Associated Press Writer Mon Mar 30, 1:36 am ET

wpeA.jpg (9436 bytes)BEIJING – The Beijing Chest Hospital was packed with people on a recent weekday morning. In the waiting area, Wang Chong, a migrant worker who has been fighting tuberculosis for several months, was facing a dilemma: Does he continue treatment that has already cost him more than $5,000 or stop before his savings are wiped out?

It's not only his health at stake. If Wang stops treatment prematurely, his tuberculosis is likely to morph into one of the new, hardier strains that resist the drugs he has been using and that pose a growing threat to global public health. Countries as diverse as China , Russia and South Africa are vulnerable, and the new strains have also appeared in the United States .

"TB is now taking on a deadly new form — one that will spread further," said Cornelia Hennig, the World Health Organization's TB program coordinator for China . "We can choose: Either we act now with rational and proven approaches, or we pay later with a worsening epidemic."

The WHO is trying to bring renewed vigor to the fight with a three-day meeting of health ministers from the worst-affected countries in Beijing starting April 1. Also attending are WHO Director-General Margaret Chan and Bill Gates, co-chair of the Bill & Melinda Gates Foundation, a major contributor to research on global health problems. Countries are expected to draw up five-year plans to prevent and control the spread of drug-resistant TB.

TB is caused by germs that spread when a person with active TB coughs, sneezes or speaks. It's ancient and treatable but now has evolved into stronger forms: multidrug-resistant TB, which does not respond to two top drugs, and extensively drug-resistant TB, which is virtually untreatable. TB is usually treated in six months with a $20 cocktail of four antibiotics, but its drug-resistant form takes up to two years to fight.

One of the culprits: health care systems that lose track of patients who do not complete their courses of treatment, allowing the TB bacteria to develop resistance to normally potent medicines.

This is also a problem in India , where rural health care is often poor and there is little control over the sale of anti-TB drugs; Russia , which faces a shortage of qualified medical staff and drugs; and South Africa , where the disease thrives amid an AIDS epidemic that has weakened the immune systems of people with HIV.

An estimated half a million people in the world are already infected with drug-resistant TB, nearly a quarter of them in China . Most are still waiting for help, which only increases the risk.

Less than 5 percent of people suffering from drug-resistant TB worldwide are properly treated, said Mark Harrington, executive director of Treatment Action Group, a U.S.-based health advocacy group.

"So most of the people are going around coughing and spreading multidrug-resistant TB," he said. "But most countries have not yet started to take it seriously."

Though the problem is mainly confined to developing countries, health experts warn the risk is widespread as people and their diseases cross the globe. An intercontinental scare was set off two years ago when an American lawyer with drug-resistant TB flew to several countries and back to attend a wedding.

In the U.S., even as TB rates fall, drug resistant strains are showing up in California and other states with large immigrant communities, because many people come from or travel frequently to countries such as Mexico, India and China where TB is a greater risk.

International experts recommend that TB treatment centers monitor their patients rigorously, supplying them with medication and watching them swallow every dose.

In the past decade, China made marked progress in fighting tuberculosis, which until last year was the most fatal infectious disease. Once a person tests positive for TB at a hospital, an Internet-based reporting system helps health officials channel the infected patients to special TB facilities run by the communicable diseases agency.

The Health Ministry says more than 90 percent of new infections are cured every year. But China still has 112,000 people with drug-resistant TB, according to the WHO. Experts say only a few thousand of them are receiving proper treatment.

An underfunded health care system means many TB facilities can't closely track every patient, while most of the 130 million highly mobile migrants from rural China don't qualify for free treatment given to urban residents. Guangdong province, where most of China's export factories are located and home to many migrants, has more TB infections than any other province.

China is developing an electronic system to track infected migrants, the WHO's Hennig said. The government has also promised revamping of health care with a $124 billion investment over the next three years.

The Health Ministry says it is working on a national survey of drug-resistant TB patients and plans to roll out treatment to them, but did not say when. It said treating drug-resistant TB is a hundred times more expensive than normal TB.

Aid agency Doctors Without Borders, also known as Medecins Sans Frontieres, said it was trying for two years to start a drug-resistant TB program in Inner Mongolia but gave up because China wanted too much control over the operation's finances and other issues. The Health Ministry had no immediate comment.

"We are rather frustrated about it ... and the patients continue to go untreated," said MSF's operational coordinator in Brussels, Luc van Leemput, who was involved in the negotiations. "I hope that the Chinese government is going to get its act together and provide access to treatment for those patients who need it."

 

64 infected by hepatitis at hospital in China

Thu Apr 2, 3:46 am ET

BEIJING – Police have detained the director of a Chinese hospital where at least 64 people were infected with the potentially deadly liver disease hepatitis C after receiving transfusions from blood collected illegally, state media reported.

The infections were discovered in September after a patient who had received a transfusion during an operation tested positive for the disease, the Xinhua News Agency reported Wednesday.

The hospital in the southwestern city of Pingtang traced the transfusion to a donor in another province who had sold as many as 42 pints (20 liters) of blood to the hospital from 1998 to 2002.

Further tests showed that by Tuesday, 64 patients had been infected with hepatitis C through blood transfusions from the donor, who was a hepatitis C carrier, the report said.

Xinhua said director Li Changhe was detained on suspicion of illegally collecting and providing blood.

A woman who answered the phone at the hospital on Thursday said no one was available to comment. Police in Pingtang said they were not authorized to speak to the media and referred questions to the county government, where calls rang unanswered.

Hepatitis C results in the swelling of the liver and can cause stomach pain, fatigue and jaundice. It may eventually result in liver failure. Even when no symptoms occur, the virus can slowly damage the liver.

China 's rules on blood collection were tightened following revelations that blood-buying rings were responsible for infecting thousands of people with HIV in rural areas of central China during the mid-1990s.

Last year, China said agents who collect or supply blood that causes at least five people to contract AIDS, hepatitis B, hepatitis C or syphilis, or that leads to severe anemia or organ malfunction, could face 10 years to life in prison.

 

NJ (US) warns nearly 3,000 to get tested for hep B

By BETH DeFALCO, Associated Press Writer Beth Defalco, Associated Press Writer Thu Apr 2, 5:20 pm ET

TRENTON, N.J. – New Jersey officials have advised nearly 3,000 people who share a doctor to get tested after five cancer patients who visited the physician were found to have hepatitis B.

Two cases of hepatitis B were confirmed in late February as connected with the office of Dr. Parvez Dara, an oncologist with offices in Toms River and Manchester , near the Jersey Shore , Marilyn Riley, spokeswoman for the state Health Department, said Thursday.

Health officials recently learned of three more cases, all in Toms River , in which the patients were also under Dara's care.

"These were older adults who didn't have other risk factors, so that is what raised a red flag," Riley said.

Ocean County decided to send a letter to all Dara's patients dating to 2002. The March 28 letter warns them of the risk and suggests they be tested for the liver diseases hepatitis B and hepatitis C and for HIV, the virus that causes AIDS.

Linda Bradford of Bayville said she's worried about her husband's health after hearing news of the outbreak.

"The first thing I did was call my husband," Bradford told WCBS-TV. "I was terrified. Oh my God, what's going on here?"

Hepatitis B is transmitted through exposure to infected blood, often by sexual contact or infected needles. Dara's office treats patients with blood disorders and cancer, some of whom receive chemotherapy there.

"The evidence that's available suggests the infections could be linked to the method the clinical staff used to administer injectable medications," such as chemotherapy, Riley said. "There's no evidence to suggest the medications were a problem."

Dara faces suspension of his medical license in connection with the outbreak and for other alleged health code violations. A hearing is scheduled for Friday before the state Board of Medical Examiners.

Until then, he is performing only patient consultations, not procedures, said his lawyer, Robert Conroy. Neither of Dara's offices were open Thursday.

According to a report by the state epidemiology division, Dara has infection control violations dating to 2002, including violations of standards of the federal Occupational Safety and Health Administration.

Conroy said that there is no proof the patients got the disease from Dara's office and that other factors aren't being considered. All five patients were also seen at Community Medical Center in Toms River , he said.

Health officials said they ruled the hospital out as a possible source of the infection.

Hepatitis B is transmitted through exposure to infected blood, often by sexual contact or infected needles.

Conroy said three patients were found to have dormant hepatitis infections that might have been noticed only after they started cancer treatments, which can suppress the body's immune system.

Because the patients live in the same area, he said, there could be another possible source.

"Absent any evidence, it is just as likely that those patients were infected (at) ... a common eatery," he wrote in a letter to the Medical Examiners Board.

Meanwhile, Conroy said Dara has received only support from his patients.

"The doctor has never felt more appreciated by his patients than he does right now," he said.

Ocean County Health Department spokesman Edward Rumen said no new cases have been reported since the alert was issued.

 

New South African research centre to tackle HIV/TB

[ DURBAN ] The University of KwaZulu-Natal (UKZN) in South Africa will host a new research centre dedicated to exploring ways of controlling the HIV/tuberculosis co-epidemic.

The US$30 million KwaZulu-Natal Research Institute for Tuberculosis and HIV (K-RITH) to be built at the university's Nelson Mandela School of Medicine in Durban, will also train a new generation of African scientists in tuberculosis (TB) and HIV research.

K-RITH will initially focus on developing more rapid and effective tests for TB, characterising strains of TB and immune system responses to the infection, particularly in HIV positive patients, and studying recurrent TB infections.

The US-based Howard Hughes Medical Institute (HHMI) will collaborate with K-RITH on research and is contributing US$20 million to the construction of the centre, which will include two floors of high-level biosafety laboratories for TB research.

The research will be led by two investigators from HHMI, William Jacobs from the Albert Einstein College of Medicine and Bruce Walker of the Massachusetts General Hospital and two investigators from UKZN, Willem Sturm, dean of the medical school and K-RITH's interim director and Salim Karim, director of the Centre for AIDS Programme of Research in South Africa.

HHMI has also committed a further US$40 million to the initiative over the next ten years to provide K-RITH with research funding.

To build up capacity for the centre, the HHMI distributed more than US$1.1 million in grants in 2008 to South African and US scientists. It will also provide US$3 million this year to construct temporary laboratory facilities for the TB research programme.

The K-RITH initiative offers an unusual opportunity for a comprehensive approach to research, says Karim. "Usually research is very focused, but K-RITH incorporates the entire spectrum of research. There is the laboratory side, the clinical side and the community or public health implications," he told SciDev.Net.

HHMI's vice-president Peter Bruns says that Durban was chosen as the venue not only because it is the epicentre of the intertwined epidemic of multi-drug resistant TB and HIV but also because the UKZN scientists involved have been extensively involved in international research collaboration.

Construction of the six-story centre, which will be integrated into the existing Doris Duke Medical Research Institute, is expected to start towards the end of September this year.
