WHO Calls For High-Priced Drugs For Millions With Hepatitis C

Originally published on Wed April 9, 2014 11:27 am

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.
Saurabh Das AP

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

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.

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.

Deadly MERS Virus Circulates Among Arabian Camels

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

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

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

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.

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.
