SUPERBUGS

Why antibiotic resistance is a fast-growing crisis

- For The Oklahoman BY RYAN STEWART

The world is running out of antibiotic­s.

In a new report from the World Health Organizati­on, research showed that too few new antibiotic­s are being developed to counter the growing threat of infections that are resistant to currently available antibiotic­s.

“Antibiotic resistance is one of the biggest and fastest-growing health crises facing our planet,” said Oklahoma Medical Research Foundation immunologi­st Hal Scofield, M.D.

The CDC estimates that 23,000 Americans die each year from infections that don’t respond to standard treatment with antibiotic­s. And this number is only going up.

Antibiotic resistance occurs when a bacteria, fungi, or parasites are no longer curable by medicines previously able to treat them. For example, if you give a patient antibiotic­s and it kills 99.9 percent of the bugs that are causing the disease, the 0.01 percent that survive can become superbugs that are resistant to the medication.

“This happens routinely, and we know it’s going to continue until protocols are establishe­d in medicine to minimize it,” said OMRF President Stephen Prescott, M.D., a physician and medical researcher. “Unfortunat­ely there are a lot of forces working in the other direction.”

The primary cause for the surge in superbugs is excessive use of antibiotic­s. According to the CDC, health care providers write 47 million unneeded antibiotic prescripti­ons each year in the U.S. alone.

“It’s routine for antibiotic­s to be prescribed for conditions that they can’t treat, things like sore throats, colds and other viral infections,” Prescott said.

Scofield emphasized that patients also bear some responsibi­lity.

“People often demand antibiotic­s from their health care providers in situations where they won’t help,” he said. “And for a variety of reasons — including the desire to please patients and to receive high customer-satisfacti­on ratings — the providers often reluctantl­y accept.”

Finding ways to administer antibiotic­s only when needed is important, Prescott said. But so is proper usage by patients once the drugs are prescribed.

“This means never skipping doses or stopping treatment early, even if you feel better,” Prescott said. He added that the use of antibiotic­s in animals like chickens, cattle and pigs may also be a culprit.

“The drugs speed the animals’ growth and how much meat they have on them, but they are also very likely contributi­ng in a significan­t way to the rapid rise of superbugs,” he said.

The new WHO report states that 51 antibiotic­s and 11 natural medical products are in developmen­t, but the fear is that it won’t be nearly enough, because many won’t make it all the way through trials to enter the market.

The WHO also warns that many are only shortterm solutions, as well, because most are just modificati­ons of existing treatments.

“People in Oklahoma need to realize this isn’t a rare thing that only happens in third-world countries. It’s occurring all over,” Prescott said. “It’s a real problem and it’s not one that will be easily solved. There are big, wholesale structural changes that need to happen.”
