Clostidium difficile Most Recent Research Discussed By ASM and Dr. Alice Guh, MD, MPH of the CDC

Clostridium difficile is an increasingly important problem being faced by clinical microbiologists. From 1993 to 2009, incidence of C. difficile increased fourfold (85,700 cases increased to 336,600 cases) in the United States. Because of this, it has become a significant area of research, as researchers search for better antimicrobial therapies, diagnostic assays, and prevention tactics.   ASM recently invited Alice Guh, MD, MPH, of the Centers for Disease Control and Prevention, to present the most recent C. difficile research as part of the Hot Topics in Clinical Microbiology series*. In her presentation, ‘Update on Clostridium difficile Infection’, Guh first describes the changing epidemiology of C. difficile infections (CDI), updating the data from the CDC’s Emerging Infections Program (EIP) and their long-term surveillance of CDI within the United States.

Guh further reviews current CDI diagnostic testing and its associated challenges. She highlights the benefits and downfalls of traditional enzyme immunoassay to detect C. difficile toxins compared to the nucleic acid amplification tests (NAAT) first put to widespread use in 2009.

Finally, Guh describes the role of asymptomatic carriers in C. difficile transmission. Her review of the literature presents best practices to trace transmission from asymptomatic carriers as well as suggested strategies to stop this transmission.

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.

Super-bugs Capture Attention As A Worldwide Health Threat

About 2 million Americans catch drug-resistant infections each year, and 23,000 die, according to the CDC.

As superbugs capture attention as a worldwide health threat, Washington University will be part of a national campaign against drug-resistant bacteria with a $2 million federal grant. The Centers for Disease Control and Prevention awarded $14 million to 25 medical schools and other organizations for research into how microorganisms in the body, known as the microbiome, can track and prevent infections by outsider, drug-resistant germs.

“Understanding the role the microbiome plays in antibiotic-resistant infections is necessary to protect the public’s health,” Dr. Tom Frieden, CDC director, said in a statement. “We think it is key to innovative approaches to combat antibiotic resistance, protect patients, and improve antibiotic use.”

The microbiome includes “good” bacteria and other beneficial organisms that live in the skin and in the digestive and respiratory tracts. Antibiotics that are supposed to fight “bad” bacteria can disrupt the natural habitat by unbalancing the good and bad. Then drug-resistant bacteria can take over and create an environment for out-of-control bugs, including methicillin-resistant staphylococcus aureus (MRSA), carbapenem-resistant enterobacteriaceae (CRE) and clostridium difficile (C. diff.).

Overexposure to antibiotics has been blamed for the rise in superbugs, with the CDC estimating that one in three antibiotic prescriptions is unnecessary.

The research project will look at how early exposure to antibiotics affects the development of the microbiome and whether there are better ways to protect the microbiome.

Four teams of researchers at Washington University were named to the local project:

  • Dr. Jeffrey Henderson will lead a team working to identify how diet and metabolism interact with the gut microbiome in a study to combat C. diff. intestinal infections.
  • A team led by Gautam Dantas will study the long-term effects of antibiotic therapy in premature infants and how their digestive microbiomes are affected.
  • Dr. Jennie Kwon will study antibiotics and the microbiome as it relates to pneumonia.
  • Dr. Brian Gage will help look at hemorrhages linked to the use of blood thinners.

The United Nations General Assembly focused on superbugs — in a rare discussion of health issues. The meeting comes after a new superbug resistant to last-resort antibiotics infected a Pennsylvania woman over the summer, and a resistant strain of E. coli was recently found in a 2-year-old Connecticut girl.

The CDC recommends increased testing for the superbug gene among certain types of E. coli bacteria that show resistance to the powerful antibiotic colistin. The gene spreads readily among bacteria, and it could make these multi-drug-resistant strains almost impossible to treat.

A cluster of gonorrhea infections in Hawaii has shown resistance to all treatments. Doctors are increasingly worried that the common sexually transmitted disease is gaining strength as one of the most urgent superbug threats. If untreated, the disease can lead to infertility.

Centers for Disease Control and Prevention (CDC) Awards Research Contract To Synthetic Biologics For Microbiome Assessment and Approaches To Better Combat Antibiotic Resistance

Synthetic Biologics, Inc. www.syntheticbiologics.com (PRNewsFoto/Synthetic Biologics, Inc.)

“To protect people, their microbiomes, and the effectiveness of antibiotics, this project is an example of applied research that has the potential to produce innovative public health approaches to better combat antibiotic resistance.”

Synthetic Biologics, Inc.  a clinical stage company focused on developing therapeutics to protect the gut microbiome while targeting pathogen-specific diseases, announced today it has been awarded a contract by the Centers for Disease Control and Prevention (CDC).

The award will support research conducted during the Company’s ongoing randomized, placebo-controlled Phase 2b proof-of-concept clinical study of SYN-004 (ribaxamase), designed to protect the gut microbiome from the unintended effects of certain commonly used intravenous (IV) beta-lactam antibiotics for the prevention of C. difficile infection (CDI), antibiotic-associated diarrhea (AAD) and the emergence of antibiotic-resistant organisms.

“Antibiotics are life-saving medicines, but they also can disrupt a person’s microbiome and increase the risk for drug-resistant infections,” said Dr. Clifford McDonald, Associate Director of Science for CDC’s Division of Healthcare Quality Promotion. “To protect people, their microbiomes, and the effectiveness of antibiotics, this project is an example of applied research that has the potential to produce innovative public health approaches to better combat antibiotic resistance.”

The contract, awarded through the CDC’s Advanced and Innovative Solutions to Improve Public Health Broad Agency Announcement (BAA) 2016-N-17812, will support CDC’s efforts to assess how selective pressure from IV antibiotics may lead to the emergence of antibiotic resistance in the gut microbiome. The funding will also support research to evaluate ribaxamase’s ability to reduce selective pressure associated with the emergence of antibiotic-resistant organisms in the gut microbiomes of patients enrolled in the Company’s ongoing Phase 2b clinical trial. The Company will examine DNA isolated from longitudinal samples obtained during the clinical trial and look for changes to the patient’s gut resistome, specifically examining for alterations in the presence and/or abundance of antibiotic resistance genes.

“Synthetic Biologics is proud to have the support of the U.S. Government in its efforts to study the role of antibiotics in mediating resistance in the gut microbiome,” said Jeffrey Riley, President and Chief Executive Officer. “Ribaxamase’s strategy of degrading certain IV beta-lactam antibiotics before they are excreted into the GI tract has the potential to protect the gut microbiome from disruption by these antibiotics without inhibiting their ability to fight primary infections as well as mitigate conditions conducive to antibiotic-resistance development. We look forward to our collaboration with CDC and to furthering their initiative to assess and address rising global concerns for the proliferation of antibiotic resistance.”

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.

Saving patients from sepsis is a race against time

CDC calls sepsis a medical emergency; encourages prompt action for prevention, early recognition

Sepsis is caused by the body’s overwhelming and life-threatening response to an infection and requires rapid intervention. It begins outside of the hospital for nearly 80 percent of patients. According to a new Vital Signs report released by CDC, about 7 in 10 patients with sepsis had used health care services recently or had chronic diseases that required frequent medical care. These represent opportunities for healthcare providers to prevent, recognize, and treat sepsis long before it can cause life-threatening illness or death.

SepsisCDCThinkSepsis

“When sepsis occurs, it should be treated as a medical emergency,” said CDC Director Tom Frieden, M.D., M.P.H. “Doctors and nurses can prevent sepsis and also the devastating effects of sepsis, and patients and families can watch for sepsis and ask, ‘could this be sepsis?’”   

Certain people with an infection are more likely to get sepsis, including people age 65 years or older, infants less than 1 year old, people who have weakened immune systems, and people who have chronic medical conditions (such as diabetes). While much less common, even healthy children and adults can develop sepsis from an infection, especially when not recognized early. The signs and symptoms of sepsis include: shivering, fever, or feeling very cold; extreme pain or discomfort; clammy or sweaty skin; confusion or disorientation; shortness of breath and a high heart rate.

SepsisCDCBannerHealthcareMatters

According to the Vital Signs report, infections of the lung, urinary tract, skin, and gut most often led to sepsis. In most cases, the germ that caused the infection leading to sepsis was not identified. When identified, the most common germs leading to sepsis were Staphylococcus aureus, Escherichia coli (E. coli), and some types of Streptococcus.

 

Health care providers, patients and their family members can work as a team to prevent sepsis.

Health care providers play a critical role in protecting patients from infections that can lead to sepsis and recognizing sepsis early. Health care providers can:

·         Prevent infections. Follow infection control requirements (such as handwashing) and ensure patients to get recommended vaccines (e.g., flu and pneumococcal).

·         Educate patients and their families. Stress the need to prevent infections, manage chronic conditions, and, if an infection is not improving, promptly seek care. Don’t delay.

·         Think sepsis. Know the signs and symptoms to identify and treat patients earlier.

·         Act fast. If sepsis is suspected, order tests to help determine if an infection is present, where it is, and what caused it. Start antibiotics and other recommended medical care immediately.

·         Reassess patient management. Check patient progress frequently. Reassess antibiotic therapy 24-48 hours or sooner to change therapy as needed. Determine whether the type of antibiotics, dose, and duration are correct.

CDC is working on five key areas related to sepsis:

·         Increasing sepsis awareness by engaging clinical professional organizations and patient advocates.

·         Aligning infection prevention, chronic disease management, and appropriate antibiotic use to promote early recognition of sepsis.

·         Studying risk factors for sepsis that can guide focused prevention and early recognition.

·         Developing tracking for sepsis to measure impact of successful interventions.

·         Preventing infections that may lead to sepsis by promoting vaccination programs, chronic disease management, infection prevention, and appropriate antibiotic use.
