Antibiotic Resistance IS A Serious Global Health Concern

C.diff. Treatments

A Nevada woman has died from an infection resistant to all available antibiotics in the United States, public health officials report.

According to the Centers for Disease Control and Prevention, the woman’s condition was deemed incurable after being tested against 26 different antibiotics.

Though this isn’t the first case of pan-resistant bacteria in the U.S., at this time it is still uncommon. Still, experts note that antibiotic resistance is a growing health concern globally and call the newly reported case “a wake up call.”

“This is the latest reminder that yes, antibiotic resistance is real,” Dr. James Johnson, a professor specializing in infectious diseases at the University of Minnesota Medical School, told CBS News. “This is not some future, fantasized armageddon threat that maybe will happen after our lifetime. This is now, it’s real, and it’s here.”

According to the report, the woman from Washoe County was in her 70s and had recently returned to America after an extended trip to India. She had been hospitalized there several times before being admitted to an acute care hospital in Nevada in mid-August.

Doctors discovered the woman was infected with carbapenem-resistant Enterobacteriaceae (CRE), which is a family of germs that CDC director Dr. Tom Frieden has called “nightmare bacteria” due to the danger it poses for spreading antibiotic resistance.

The woman had a specific type of CRE, called Klebsiella pneumoniae, which can lead to a number of illnesses, including pneumonia, blood stream infections, and meningitis. In early September, she developed septic shock and died.

The authors of the report say the case highlights the need for doctors and hospitals to ask incoming patients about recent travel and if they have been hospitalized elsewhere.

Other experts say it underscores the need for the medical community, the government and the public to take antibiotic resistance more seriously.

According to the CDC, at least two million people become infected with antibiotic resistant bacteria each year, and at least 23,000 die as a direct result of these infections.

The World Health Organization calls antibiotic resistance “one of the biggest threats to global health.”

A grim report released last year suggests that if bacteria keep evolving at the current rate, by 2050, superbugs will kill 10 million people a year.

While scientists are working to develop new antibiotics, that takes time, and experts encourage doctors and the public to focus on prevention efforts.

One of the most important ways to prevent antibiotic resistance is to only take antibiotics only when they’re necessary.

“Drug resistance like this [case] generally develops from too much exposure to antibiotics,” assistant professor of pediatrics at Johns Hopkins University School of Medicine and director of the Pediatric Antimicrobial Stewardship Program at The Johns Hopkins Hospital, told CBS News. “Every time you’re placed on an antibiotic it’s important to question if it’s absolutely necessary and what’s the shortest amount of time you can take this antibiotic for it to still be effective.”

Johnson notes that medical tourism – the practice of traveling to another country to obtain medical treatment, typically at lower cost – may no longer be worth the risk. “With this [antibiotic] resistance issue, the risk/benefit of this approach really changes and I think that people really need to be aware and seriously consider if it’s a good idea given the possibility of this kind of thing,” he said.

Frequent hand washing, particularly in healthcare settings, is also extremely important in preventing the spread of germs.

Centers for Disease Control and Prevention (CDC) Provides Updates On C. difficile Infection Management and Treatment

cdc logo

According to the Centers for Disease Control and Prevention (CDC), Clostridium difficile infection (C. difficile) “has become the most common microbial cause of healthcare-associated infections in U.S. hospitals and costs up to $4.8 billion each year in excess health care costs for acute care facilities alone.”

Statistics provided by the CDC suggest that C. difficile cause nearly 500,000 infections in patients in the US annually.

In one study noted by the CDC, among infected patients, nearly 29,000 died within 30 days of being diagnosed, and more than half of those deaths (15,000) were directly attributable to C. difficile infection.

With C. difficile infection prevention being declared a national priority by the CDC, researchers, public health officials, infectious disease specialists, and others continue to research more effective ways to combat this microbe. Below, we’ve collected links and information on several recent developments.

THE GOOD NEWS
The Center for Infectious Disease Research and Policy (CIDRAP) recently -hospital-stewardship-lowers-antibiotic-use-infections”>reported some good news about the effectiveness of antibiotic stewardship programs (ASPs) in reducing antibiotic usage, especially among patients in the intensive care unit.

Citing the results of a meta-analysis published in Antimicrobial Agents and Chemotherapy, the CIDRAP report noted that, following the implementation of an ASP, “hospital antimicrobial consumption across all studies declined by 19.1%, and antibiotic costs fell by 33.9%. Though a modest decrease of 12.1% in antimicrobial use occurred in general medical wards, antimicrobial use in ICUs fell by 39.5% across the four studies that looked at that parameter.”

The meta-analysis also found that ASPs were effective in curbing the use of non-antibiotic therapies. In the six studies that also monitored antifungal prescription rates, the authors reported a 39.1% decline after ASP initiation.

The use of third- and fourth generation antibiotics (such as cephalosporins, vancomycin, tigecycline, linezolid, imipenem, meropenem, and fluoroquinolones) declined by 26.6% in facilities that implemented an ASP.

The meta-analysis found that bacteria infection rates declined 4.5% in the studies that measured clinical outcomes, and length of hospital stay fell by nearly 9% in studies that measured that metric.

However, the CIDRAP report noted that ASP implementation was not “associated with declining risks for Clostridium difficile (C diff) infections.” The authors of the meta-analysis did note that, in three studies that evaluated C difficile rates, “significant publication bias favored studies that reported ASPs’ negative effects.”

Let’s just get right to the heart of this report from Reuters:

“Fifteen years after the U.S. government declared antibiotic-resistant infections to be a grave threat to public health, a Reuters investigation has found that infection-related deaths are going uncounted, hindering the nation’s ability to fight a scourge that exacts a significant human and financial toll. Even when recorded, tens of thousands of deaths from drug-resistant infections – as well as many more infections that sicken but don’t kill people – go uncounted because federal and state agencies are doing a poor job of tracking them.

The Centers for Disease Control and Prevention (CDC), the go-to national public health monitor, and state health departments lack the political, legal and financial wherewithal to impose rigorous surveillance.”

The report goes on to outline how incomplete, “patchwork” infection reporting requirements for hospitals, and lax requirements in many states regarding physicians’ responsibilities when filling out death certificates, have led to deaths caused by (or at the very least associated with) MRSA and other drug-resistant pathogens to be “grossly under-reported.”

For example, according to Reuters, only 17 states require notification of C. difficile infections. Only two of the so-called “superbug” infections (MRSA bacteremia and C. difficile) are required to be reported to the CDC’s National Healthcare Safety Network surveillance program.

As they say, read the whole thing.

The authors of an article published in Clinical Microbiology and Infection  reported on a study that compared treatment with tigecycline to standard therapy in adult patients with severe C. difficile infection (sCDI).

The retrospective cohort study compared outcomes in patients with sCDI who received tigecycline alone to outcomes in patients who received standard oral vancomycin combined with intravenous metronidazole.

The primary study outcome was clinical recovery (as determined by European Society of Clinical Microbiology and Infectious Diseases guidelines); secondary outcomes were “in-hospital and 90-day all-cause mortality and relapse, colectomy and complication rates.”

A total of 90 patients with sCDI were treated (45 in each group). Patients treated with tigecycline monotherapy tended to do better in terms of cure rate, complicated disease, and CDI sepsis.

The authors reported that, compared to the group that received standard therapy, the tigecycline group had “significantly better outcomes of clinical cure (34/45, 75.6% vs. 24/45, 53.3%; p=0.02), less complicated disease course (13/45, 28.9% vs. 24/45, 53.3%; p=0.02) and less CDI sepsis (7/45, 15.6% vs. 18/45, 40.0%; p=0.009).”

Rates of mortality, disease relapse, and other measures were similar between the groups.

These results led the researchers to conclude that “tigecycline might be considered as a potential candidate for therapeutic usage in cases of sCDI refractory to standard treatment.”

Our good friends at Contagion Live recently reported on a study that has uncovered how the C. difficile bacteria produces toxins, which could aid the development of nonantibiotic drugs to fight C. difficile infection.

According to Contagion Live, C. difficile produces two toxins, toxin A and toxin B, that “cause life-threatening diarrhea as well as pseudomembranous colitis, toxic megacolon, perforations in the colon, sepsis and rarely death.”

Researchers at the University of Texas found that strains of C. difficile with a mutation in a particular Agr locus in their genome could not produce the toxins.

“Identifying a pathway responsible for activating the production of the toxins… opens up a unique therapeutic target for the development of a novel nonantibiotic therapy for C. difficile infections,” said the study authors.

The Contagion Live article includes a quote from author Charles Darkoh, PhD, on the potential implications of these findings.

“By crippling their toxin-making machinery, C. diff cannot make toxins and thus cannot cause disease. My laboratory is already working on this and was awarded a 5-year National Institutes of Health grant to investigate and develop an oral compound we have identified that inactivate the toxins and block the toxin-making machinery of C. diff by targeting this pathway,” he said.
