Advocates demonstrate in favor of cheaper generic drugs to treat hepatitis C in New Delhi on March 21. The disease is common among people who are HIV positive.

Authors of the first-ever global guidelines for treating hepatitis C went big Tuesday, advocating for worldwide use of two of the most expensive specialty drugs in the world.

The new guidelines from the World Health Organization give strong endorsement to the two newest drugs. Gilead Sciences' Sovaldi costs $1,000 per pill, or $84,000 for a 12-week course of treatment. Olysio, sold by Johnson & Johnson's Janssen Pharmaceuticals unit, costs $66,360 for a three-month course.

Cholesterol Guidelines Could Mean Statins For Half Of Adults Over 40

Originally published on Thu March 20, 2014 1:04 pm

If new guidelines are followed fully, half the medicine chests in America could eventually be stocked with cholesterol-lowering drugs such as atorvastatin, the generic form of Lipitor.
Bill Gallery AP

When sweeping new advice on preventing heart attacks and strokes came out last November, it wasn't clear how many more Americans should be taking daily statin pills to lower their risk.

A new analysis provides an answer: a whole lot. Nearly 13 million more, to be precise.

Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.

It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study published Tuesday.

So far MERS has sickened more than 180 people, killing at least 77 of them — an alarming 43 percent. But scientists haven't been sure where the virus came from or how people catch it.

Research Shows New Flu Viruses Often Arise In Domestic Animals

New research finds a close connection between the flu that devastated the horse population in North America in the 1870s and the avian flu of that period.

As flu-watchers like to say, you can always count on influenza virus to surprise.

The latest revelation is that scientists have apparently been wrong about where new flu viruses come from. The dogma is that they always incubate in wild migratory birds, then get into domestic poultry, and then jump into mammals — especially pigs and humans.

Maker Of $1,000 Hepatitis C Pill Looks To Cut Its Cost Overseas

A girl with hepatitis C holds a medical report while being treated at a hospital in Hefei, China, in 2011. China has one of the greatest burdens of hepatitis C, but it's still not clear whether a deal for lower prices for a new drug from Gilead Sciences will apply there.

An effective new medicine is developed as a cure for a major disease. The drug company prices the medicine at tens of thousands of dollars for a course of treatment. How can the disease-curing medicine be made accessible to patients who need it, most of whom live in low- and middle-income countries?

There's new evidence that widely prescribed testosterone drugs — touted for men with flagging libidos and general listlessness — might increase the risk of heart attacks.

A study of more than 55,000 men found a doubling of heart attack risk among testosterone users older than 65, compared with men who didn't take the drug.

As China gets ready to usher in the Year of the Horse on Friday, millions of them will find it hard to buy chicken for traditional Lunar New Year feasts. That's a mark of the nation's growing anxiety about a poultry-borne flu virus called H7N9.

On Tuesday, Hong Kong agricultural workers will begin destroying 20,000 chickens. The bird flu virus H7N9 was found in a single live bird from a farm in neighboring Guangdong Province.

Half Of A Drug's Power Comes From Thinking It Will Work

Originally published on Fri January 10, 2014 1:37 pm

When you take a pill, you and your doctor hope it will work — and that helps it work.

That's not a new idea. But now researchers say they know just how much of a drug's effect comes from the patient's expectation: at least half.

When patients in the midst of a migraine attack took a dummy pill they thought was a widely used migraine drug, it reduced their pain roughly as much as when they took the real drug thinking it was a placebo.

$1,000 Pill For Hepatitis C Spurs Debate Over Drug Prices

Originally published on Thu February 6, 2014 1:43 pm

Federal regulators this month opened a new era in the treatment of a deadly liver virus that infects three to five times more people than HIV. Now the question is: Who will get access to the new drug for hepatitis C, and when?

The drug Sovaldi will cost $1,000 per pill. A typical course of treatment will last 12 weeks and run $84,000, plus the cost of necessary companion drugs. Some patients may need treatment for twice as long.

Gene Therapy Keeps 'Bubble Boy' Disease At Bay In 8 Children

David Vetter was born without a functioning immune system and spent his life in a bubble that protected him from germs. He died at age 12 in 1984. Scientists are using gene therapy to treat the disorder so that children can live normally.
Science Source

Researchers say they are achieving success in curing the genetic defect that causes some children to be born without immune defenses, a rare condition made famous in the 1970s by a Texas boy who lived most of his short life in a sterile "bubble."

Scientists now report that 8 out of 9 young children given gene therapy for a type of severe combined immunodeficiency disease, called SCID-X1, are alive and living amid the everyday microbial threats that would otherwise have killed them. The oldest is just over 3 years old.

Hoped-For AIDS Cures Fail In 2 Boston Patients

HIV has reappeared in the blood of two Boston patients who scientists had hoped had been cured of their infections.

This disappointing development, reported by The Boston Globe's Kay Lazar, is yet another cautionary tale of how researchers can never afford to underestimate the human immunodeficiency virus's ability to hide out in patients' bodies and overcome their most ingenious efforts to eliminate it.

"The United States should be at the forefront of new discoveries into how to put people into long-term remission without requiring lifelong therapies — or better yet, eliminate it completely," Obama said at a meeting in the Eisenhower Executive Office Building next to the White House.

How A Vitamin D Test Misdiagnosed African-Americans

By the current blood test for vitamin D, most African-Americans are deficient. That can lead to weak bones. So many doctors prescribe supplement pills to bring their levels up.

But the problem is with the test, not the patients, according to a new study. The vast majority of African-Americans have plenty of the form of vitamin D that counts — the type their cells can readily use.

The research resolves a long-standing paradox.

Images of the swath of devastation wrought by Typhoon Haiyan in the central Philippines are reminiscent of the tsunami's aftermath in Banda Aceh, Indonesia nearly a decade ago.

And indeed, the World Health Organization grades the great typhoon of 2013 as a Category 3 disaster – its most severe category.

"The scale [of the typhoon's damage] is huge," Dr. Richard Brennan of the World Health Organization tells Shots. "It's monumental. This is one of the biggest emergencies we've dealt with in some time."
