Antimicrobial resistance threat continues during COVID-19


The stark realities of antimicrobial resistance – including rising rates of difficult-to-treat infections, lack of a robust pipeline of future antimicrobials, and COVID-19 treatments that leave people more vulnerable to infections – remain urgent priorities, experts say.

For some patients, the pandemic and antimicrobial resistance (AMR) are intertwined.

“One patient I’m seeing now in service really underscores how the two interact,” Vance Fowler, MD, said during a June 30 media briefing sponsored by the Infectious Diseases Society of America (IDSA). A man in his mid-40s, married with a small child, developed COVID-19 in early January 2021. He was intubated, spent about 1 month in the ICU, and managed to survive.

“But since then he has been struck with a series of progressively more drug resistant bacteria,” said Dr. Fowler, professor of medicine at Duke University, Durham, N.C., and chair of the IDSA Antimicrobial Resistance Committee.

The patient acquired Pseudomonas ventilator-associated pneumonia. Although the infection initially responded to standard antibiotics, he has experienced relapses over the past few months. Through these multiple infections the Pseudomonas grew increasingly pan-resistant to treatment.

The only remaining antimicrobial agent for this patient, Dr. Fowler said, is “a case study in what we are describing ... a drug that is used relatively infrequently, that is fairly expensive, but for that particular patient is absolutely vital.”

A ‘terrifying’ personal experience

Tori Kinamon, a Duke University medical student and Food and Drug Administration antibacterial drug resistance fellow, joined Dr. Fowler at the IDSA briefing. She shared her personal journey of surviving a methicillin-resistant Staphylococcus aureus (MRSA) infection, one that sparked her interest in becoming a physician.

“I had a very frightening and unexpected confrontation with antimicrobial resistance when I was a freshman in college,” Ms. Kinamon said.

A few days after competing in a Division One gymnastics championship, she felt a gradual onset of pain in her left hamstring. The pain grew acutely worse and, within days, her leg become red, swollen, and painful to the touch.

Ms. Kinamon was admitted to the hospital for suspected cellulitis and put on intravenous antibiotics.

“However, my clinical condition continued to decline,” she recalled. “Imaging studies revealed a 15-cm abscess deep in my hamstring.”

The limb- and life-threatening infection left her wondering if she would come out of surgery with both legs.

“Ultimately, I had eight surgeries in 2 weeks,” she said.

“As a 19-year-old collegiate athlete, that’s terrifying. And I never imagined that something like that would happen to me – until it did,” said Ms. Kinamon, who is an NCAA infection prevention advocate.

When Ms. Kinamon’s kidneys could no longer tolerate vancomycin, she was switched to daptomycin.

“I reflect quite frequently on how having that one extra drug in the stockpile had a significant impact on my outcome,” she said.
