Can antibiotic resistant bacteria cause infections?

Often called superbugs, antibiotic-resistant bacteria can cause infections including lung (pneumonia), urinary tract and skin infections. CRE superbugs can spread and share their antibiotic-resistant qualities with healthy bacteria in your body. These superbugs can cause infections if they get into your bladder, blood or other areas where they don't belong. When an infection happens, it's difficult, if not impossible, to treat effectively.

What causes endocarditis in the GI tract?

Enterococci are the second most common cause of infective endocarditis. Common sources are central lines, GI or GU tracts after manipulation, damaged mitral or aortic valve infections, or liver transplantation. Community-acquired endocarditis can occur, and it is usually due to E. faecalisin patients with no risk factors. Clinically, they present subacutely with fevers and constitutional symptoms. Typical signs of infection include fevers or a new murmur. Typical stigmata of endocarditis such as petechiae, Osler nodes, and Roth spots are rare and, as with other etiologies, typically occur with subacute infection rather than acute infection.

How can VRE be transmitted?

There are reports that VRE can be transmitted by direct patient contact, touching of contaminated surfaces/equipment or through hand transfer after contact with the affected patient. In almost every hospital in the US, VRE has become a serious problem. In response to this epidemic, almost every hospital now has an infectious disease committee that oversees the use of antibiotics and audits procedures at the bedside for sterility. It is here that the role of the infectious disease nurse and pharmacist is vital. The current recommendations are to 1) only use vancomycin when absolutely needed, and permission must be obtained from the board-certified infectious disease pharmacist and clinician infectious disease specialist 2) educate all healthcare workers about VRE 3) implement infection control measures including hand washing, gloves, and gowns when coming into contact with patients who have VRE and 4) maintain a clean working environment with strict aseptic control. There is evidence to support the use of an interprofessional approach to prevent nosocomial spread of VRE. Many hospitals have now enforced the use of contact isolation and regular surveillance cultures.  [17][18][19](Level V)

What is the most common clinical presentation of Enterococcus?

Enterococcus can cause a wide range of clinical diseases. The most common clinical presentation is bacteriuria, though it is becoming increasingly clear that many of these cases are due to colonization rather than infection. Other frequent causes of infection are bacteremia without endocarditis, followed by endocarditis.

What are the risk factors for vancomycin-resistant Enterococcus?

The most commonly observed risk factor is previous antimicrobial therapy. This mechanism likely is due to alteration in bowel flora. Furthermore, patients at increased risk are those with severe underlying illnesses or immunosuppression. This also includes patients with a long hospital stay, admission to long-term care facilities, extended use of antibiotics, and proximity to other patients with vancomycin-resistant Enterococcus. [8][9]

What is tigecycline used for?

Tigecycline, a glycylcycline antibiotic, can be used for patients who are intolerant to other agents. It also can be used if other infections are present with the vancomycin-resistant Enterococcus as it has good coverage against gram positives, some gram negatives, and anaerobes. Although it is off-label, it is specifically considered a preferred agent for polymicrobial intraabdominal infections. It should not be used for vancomycin-resistant Enterococcus bacteremia as it distributes primarily to tissues and achieves low serum concentrations. Typical dosing is 100 mg IV once followed by 50 mg IV twice a day. Patients should be monitored for major adverse effects such as nausea and vomiting.

Is vancomycin resistant to beta lactams?

E. faecalistends to be susceptible to beta-lactams and aminoglycosides. Vancomycin resistance is more frequent in undifferentiated E. faecalisthan resistance to aminopenicillins, stressing that beta-lactams should remain the first choice in most infections before culture data. Conversely, most strains of E. faeciumare highly resistant to beta-lactams and aminoglycosides. In general, if vancomycin-resistant Enterococcus is highly resistant to other antimicrobial therapies; the two major treatments are linezolid and daptomycin. A meta-analysis of these two therapies has shown that the overall mortality, clinical cure, microbiological cure, and relapse rate were not significantly different. Importantly, the most common genotypic causes of vancomycin resistance are VanAand VanBwhich are inducible resistance genes. As a result, patients with initially vancomycin sensitive isolates that do not respond to treatment should be re-cultured.

How Is VRE Diagnosed?

To confirm a VRE infection, your doctor will send a sample of your infected wound, blood, urine, or stool to the lab for analysis. At the lab, technicians will grow the bacteria and test it to see which antibiotics can kill the bacteria. If vancomycin can’t kill it, that confirms the existence of VRE.

What are the symptoms of VRE?

VRE can infect the bloodstream, the urinary tract (as a UTI ), and wounds associated with catheters or surgery. Bloodstream infections can cause: Fever. Chills.

How does VRE evolve?

To understand how antibiotic-resistant bacteria such as VRE emerges, it helps to first understand how bacteria and fungi change in response to medicines designed to kill them. According to the CDC Antibiotic Resistance Threats Report, germs naturally evolve constantly, and can develop new ways to avoid the effects of antibiotics. Once that happens, the resistant germ survives and multiplies, and the surviving germs, which now have resistance traits in their DNA, pass on this genetic information to subsequent generations. These resistant germs can continue to spread and pose an increasing threat to people’s health.

In fact, VRE is listed as one of the key antibiotic-resistant pathogens that pose a threat to human health in the Centers for Disease Control and Prevention’s 2019 Antibiotic ...

How is VRE spread?

VRE is typically not spread through the air like a cold or the flu and it cannot be spread through casual contact such as hugging. It is spread by direct contact with an infected person’s bodily fluids, such as blood, phlegm, urine, or stool, or by touching surfaces that have been contaminated by the bacteria.
