Antibiotic resistance a "catastrophic threat" - medical chief

LONDON (Reuters) - Antibiotic resistance poses a catastrophic threat to medicine and could mean patients having minor surgery risk dying from infections that can no longer be treated, Britain's top health official said on Monday.

Sally Davies, the chief medical officer for England, said global action is needed to fight antibiotic, or antimicrobial, resistance and fill a drug "discovery void" by researching and developing new medicines to treat emerging, mutating infections.

Only a handful of new antibiotics have been developed and brought to market in the past few decades, and it is a race against time to find more, as bacterial infections increasingly evolve into "superbugs" resistant to existing drugs.

"Antimicrobial resistance poses a catastrophic threat. If we don't act now, any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can't be treated by antibiotics," Davies told reporters as she published a report on infectious disease.

"And routine operations like hip replacements or organ transplants could be deadly because of the risk of infection."

One of the best known superbugs, MRSA, is alone estimated to kill around 19,000 people every year in the United States - far more than HIV and AIDS - and a similar number in Europe.

And others are spreading. Cases of totally drug resistant tuberculosis have appeared in recent years and a new wave of "super superbugs" with a mutation called NDM 1, which first emerged in India, has now turned up all over the world, from Britain to New Zealand.

Last year the WHO said untreatable superbug strains of gonorrhoea were spreading across the world.

Laura Piddock, a professor of microbiology at Birmingham University and director of the campaign group Antibiotic Action, welcomed Davies' efforts to raise awareness of the problem.

"There are an increasing number of infections for which there are virtually no therapeutic options, and we desperately need new discovery, research and development," she said.

Davies called on governments and organisations across the world, including the World Health Organisation and the G8, to take the threat seriously and work to encourage more innovation and investment into the development of antibiotics.

"Over the past two decades there has been a discovery void around antibiotics, meaning diseases have evolved faster than the drugs to treat them," she said.

Davies called for more cooperation between the healthcare and pharmaceutical industries to preserve the existing arsenal of antibiotics, and more focus on developing new ones.

Increasing surveillance to keep track of drug-resistant superbugs, prescribing fewer antibiotics and making sure they are only prescribed when needed, and ensuring better hygiene to keep infections to a minimum were equally important, she said.

Nigel Brown, president of the Society for General Microbiology, agreed the issues demanded urgent action and said its members would work hard to better understand infectious diseases, reduce transmission of antibiotic resistance, and help develop new antibiotics.

"The techniques of microbiology and new developments such as synthetic biology will be crucial in achieving this," he said.

U.S. plans medical, food aid for Syrian rebel fighters: sources

ROME (Reuters) - The United States plans to provide medical supplies and food to Syrian fighters, a policy shift to directly help those battling President Bashar al-Assad's forces on the ground, sources familiar with the matter said.

The sources, who spoke on condition of anonymity, said the United States continues to oppose providing lethal assistance and said it also will not provide such items as bullet-proof vests, armored-personnel vehicles and military training for now.

One source said the United States was also expected to announce a large increase in assistance to the Syrian National Coalition, the main civilian opposition group.

The announcements could come as early as Thursday in Rome, where U.S. Secretary of State John Kerry will meet coalition members at a "Friends of Syria" meeting of mostly European and Arab nations supporting the opposition.

The steps would reflect a U.S. desire to do more to help the opposition in the conflict, in which an estimated 70,000 people have died since protests against Assad erupted nearly two years ago, while stopping far short of a full-blown military intervention, for which Washington appears to have no appetite.

The moves, however, might not satisfy some members of the Syrian National Coalition, which last week said it would boycott the conference out of frustration at not receiving more assistance and only agreed to come on Monday.

COALITION SOURCE DISMISSIVE

A coalition source said the planned U.S. steps were a continuation of what he described as an American policy of wanting "no winners, no losers" in the conflict.

He said that what he viewed as the relatively small size of the coalition delegation in Rome reflected strong expectations that the meeting will not come up with substantial support.

"There is a major current in the coalition that wanted to send a message that enough is enough and that the coalition will not go along with whatever the United States has in mind and (just) say 'thank you,'" the source said.

Even if Washington were to commit to supply weapons, there was no guarantee it would keep up the supply, the source said.

"Here and there, every once in a while the armed opposition get some decent weapons, but the supply is so patchy that it renders the weapons useless," he said.

"What is the use of a sophisticated gun for example without a constant supply of ammunition?"

'HUGE DEBATE' IN OBAMA ADMINISTRATION

The White House has long resisted providing weaponry to the rebel forces, arguing there was no way to guarantee the arms might not fall into the hands of militants who might eventually use them against Western targets.

U.S. officials have said that the U.S. Defense and State Departments, under former secretary of defense Leon Panetta and former secretary of state Hillary Clinton, privately recommended that the White House arm the rebels but were overruled.

"It's a huge debate inside the administration between those that have to deal with Syria on an everyday basis, the State Department and DoD particularly, and the White House, which ... until now has vetoed any kind of outreach to the armed groups," said Andrew Tabler, senior fellow at the Washington Institute for Near East Policy, a think-tank in the U.S. capital.

"Until now we've drawn a very clear policy line away from armed groups and preferred to deal with civilians, he said, saying he did not know what the United States would ultimately decide.

The United States has not so far given aid directly to the rebel fighters and a decision to provide medical supplies and food in the form of Meals Ready to Eat (MREs), the U.S. army's basic ration, would reverse that policy.

"Why would the policy change now? The answer is because it will have to. This policy is not succeeding ... Assad is not stepping down, the post-Assad Syria is not going to be peaceful, democratic and secular," he added. "So, given this reality, we have to deal with what's going to come next."

Kerry, who took over as U.S. secretary of state on February 1, signaled that he wanted the United States to do more, saying on Monday that "the Syrian opposition is not going to be dangling in the wind wondering where the support is or if it's coming."

The source who said that the United States was expected to announce a large increase in assistance to the Syrian National Coalition said the group would receive substantially more than the rebel fighters, but declined to divulge either sum.

The United States so far has provided more than $50 million in non-lethal assistance such as communications gear and governance training to the Syrian civilian opposition, according to a U.S. State Department fact sheet.

The coalition source, however, said giving the coalition even another $50 million was a pittance compared to what he said was the $40 million a day in humanitarian aid needed to meet the basic needs of Syrian refugees and internally displaced persons.

The United States has provided some $365 million in humanitarian aid for Syrian refugees in countries such as Turkey, Jordan and Lebanon and for internally displaced people, channeling this money through non-governmental organizations.

A U.S. State Department spokeswoman declined comment.
