The Centers for Disease Control and Prevention’s Antibiotic Resistance (AR) Lab Network has detected 221 instances of bacteria with especially rare resistance genes in the United States, according to a Vital Signs report published online and expanded upon in CDC’s MMWR Weekly.
The MMWR Weekly report, “Containment of Novel Multidrug-Resistant Organisms and Resistance Mechanisms,” which goes deeper into the science behind the issue, shows that in 9 months, in all states and Puerto Rico, health department workers in the AR lab network tested 5,776 samples of highly resistant bacteria, according to Anne Schuchat, MD, principal deputy director of the CDC. These bacteria were immediately tested for unusual resistance – “those genes that were highly resistant, or rare, with special resistance that could spread,” she said.
“Of the 5,776, about 1 in 4 of the bacteria had a gene that helped it spread its resistance. And there were 221 instances of an especially rare resistance gene,” she added. This prompted intense screening, revealing “that 1 in 10 tests were also positive. Meaning the unusual resistance may have spread to other patients. And could have continued spreading if left undetected.”
The report looked at carbapenem-resistant Enterobacteriaceae (CRE) and Enterobacteriaceae with extended-spectrum beta-lactamases (ESBL) infection data from the National Healthcare Safety Network from 2006-2015 to calculate changes in the year over year proportions of these infections and how an enhanced detection and control strategy curbs carbapenem resistance.
This strategy includes components such as timely implementation of appropriate infection control measures, conducting a health care and contact investigation with follow-up, and implementing a system to ensure adherence to infection control measures.
“With independent, or single facility approaches to control spread, a dangerous type of unusual resistance in Enterobacteriaceae [ESBL phenotype] decreased by about 2% per year [(risk ratio [RR] = 0.98, P less than .001)].” With a more aggressive approach, using guidance such as CDC’s CRE toolkit, released in 2009, another type of unusual resistance [CRE] in the same bacteria (Enterobacteriaceae) decreased by nearly 15% per year (RR = 0.85, P less than .01).
The difference may be due in part to the more directed response utilized to slow the spread of the “nightmare bacteria,” once it was identified, said Dr. Schuchat.
These results show massive promise even if only partially effective, specifically for CRE.
“CDC estimates show that if only 20% effective, the containment strategy can reduce the number of nightmare bacteria [CRE] cases by 76% over 3 years in one area.”
Due to the nature of antibiotic resistance and its ability to spread, this poses a significant public health threat. Antibiotics are not simply used to treat infections but are a safety net that is used in cancer treatment, surgery, and ICU care, Dr. Schuchat pointed out. The rise of antibiotic resistance is a threat to that safety net and accounts for nearly 2,000,000 antibiotic resistant infections and approximately 23,000 deaths per year.
But aggressive responses to these infections can control their spread. Dr. Schuchat used the analogy of controlling a fire to illustrate the concept.
“Much like a fire, finding and stopping unusual resistance early when it’s just a spark protects people.”
Dr. Schuchat reiterated that simply identifying the issue is only part of the equation.
“Detection is not enough on its own. When there is a fire, somebody needs to put it out. CDC supports more than 500 local staff across the country to combat antibiotic resistance wherever it emerges.”
While the report highlights the strides that have been made in combating antibiotic resistance, Paul Auwaerter, MD, president of the Infectious Diseases Society of America, released a statement highlighting the need to further fund these efforts.
“The report spells out the need to accelerate efforts to curb resistance or face an increasing burden including novel resistance mutations that threaten health,” stated Dr. Auwaerter. “The efforts detailed in the Vital Signs report were made possible through new congressional funding in 2016 to combat antibiotic resistance. We urge Congress to sustain and to grow that investment so that further progress will prepare us to meet the future challenges of antibiotic resistance from a position of strength,” he added.
