Celebrating World Antimicrobial Awareness week!

It’s World Antimicrobial Awareness week!

Antimicrobial resistance occurs when bacteria, viruses, fungi, and parasites resist the effects of medications, making common infections harder to treat and increasing the risk of disease spread, severe illness and death. As a result of drug resistance, antibiotics and other antimicrobial medicines become ineffective and infections become increasingly difficult or impossible to treat.

Randox want to take part in the global campaign that is celebrated annually to improve awareness and understanding of Antimicrobial. We have interviewed one of our Molecular specialists, Dr Dwaine Vance on how our revolutionary Randox products aid in the fight against AMR.

What threat does AMR present to the health care environment?

In a worse-case scenario the increasingly worrying levels of AMR globally will have a significant negative effect on healthcare. Without effective antimicrobials to treat a wide arrange of infectious diseases, people will be more likely to get ill, be unresponsive to medications, which in turn will result in longer hospital stays, increased economic burden, lower levels of quality of life and ultimately poorer prognosis including elevated levels of morbidity and mortality.

 

How does Randox help in the fight against AMR?

Randox have developed and continue to develop infectious disease tests to detect a wide-range infectious disease. Randox have also included resistance gene markers within these molecular-based PCR tests to determine if an infection is sensitive or resistance to certain antimicrobials.

In addition to diagnostic tests, Randox also supply quality control materials such as third-party molecular controls and external quality assessment schemes that are used in molecular microbiology laboratories to ensure their PCR tests are working accurately and robustly. This means that labs can provide the correct information to clinicians that is vitally important to determine what antibiotic therapy is prescribed to the patient.

 

Can you tell us about any exciting developments in Randox?

Randox are continuously investing and reinvesting in our Molecular Research and Development departments. We have recently released a molecular point of care test that can discriminate between MRSA and MSSA. This means that sufficient isolation and correct primary treatment can be provided to the patient in a timelier fashion. We are in the process of releasing a UTI test that can detect over 20 UTI-related bacterial infections. In addition to these pathogens, this test also determines if the pathogens detected are resistant to commonly used antibiotics such as Trimethoprim or Vancomycin.

Furthermore, Randox are releasing an immunoassay-based point of care machine called the VerasSTAT, which includes tests for CRP and MxA biomarkers. These biomarkers are released into the bloodstream during infection as part of the body’s immune response. CRP and MxA can assist the clinician in determining if an infection is of bacterial or viral origin.

 

What measures do you think we can take to prevent the spread of AMR?

Improved personal hygiene and sanitation will reduce transmission of infectious diseases within the global population. The development of more innovative and more easily accessible antibiotics, as well as improved antibiotic stewardship within clinical settings will also help slow down the alarming rates of AMR globally. Most importantly, the creation of new syndromic style testing panels, like the tests currently provided by Randox will undoubtedly improve the clinical outcome for patients who are have an infectious disease.

We are urging the public to help raise awareness of antimicrobial resistance. Randox is committed to the ongoing development of products and services as well as our research into numerous disease areas to improve health worldwide.

Rapid PCR MRSA/SA testing now available on Vivalytic

Rapid PCR MRSA/SA testing now available on Vivalytic

Providing a quick diagnosis of methicillin resistant at the point of the care, the latest addition to the Vivalytic portfolio of tests, not only provides rapid RT-PCR results in 53 minutes but differentiates whether the bacterial strain is methicillin-resistant (MRSA) or methicillin-sensitive (MSAA) which promotes targeted therapy.

MRSA is a major multi-resistant nosocomial pathogen worldwide with the WHO estimating that the mortality rate of patient infection rates is around 50% higher compared with patients who have been infected by non-resistant Staphylococcus aureus strains.1 Moreover, the extensive period of hospitalisation, morbidity, and the associated medical costs increase significantly with an MRSA infection.2

Introducing MRSA to the vivalytic portfolio can provide high quality answers, anywhere and anytime improving patient pathways and the need for care. Significantly, introducing rapid MRSA screening at both ward level, emergency settings and before hospital elective surgery procedures allow for an effective response to identifying whether the bacteria strain is methicillin-sensitive (MSSA) or -resistant.

Making a point to care, the rapid essence and speed of Vivalytic not only showcase technology but the ability to contribute to current health risks by preventing contamination, breaking the chain of infection, and again fighting the silent pandemic of antimicrobial resistance (AMR) & superbugs.

The treatment on the front line today looks at increasing empirical antibiotic prescribing and increasing drug-resistant outbreaks. AMR is growing rapidly, with superbugs threatening the ability to treat common infectious diseases appropriately. The COVID-19 pandemic has elevated concerns over AMR and antibiotic-associated adverse events, with surges in antibiotic prescribing, hospitalisations, and drug-resistant bacterial transmissions.

Speed is key here – since the result of diagnostics with culture sampling, which is the current traditional method for MRSA testing is only available after one to three days, this PCR test for the point of care is ideal as an additional tool when speed is of the essence.

 

Few points to note about the current Vivalytic panel for MRSA/SA detection:

  • By using one single cartridge, the Vivalytic MRSA/SA test detects and differentiates between MRSA and MSSA DNA to aid in the diagnosis of MRSA infection in a speedy manner so that appropriate antibiotic treatment can be applied, and complications prevented.
  • Detection Method: Real-Time PCR
  • Result Time: 53 minutes
  • Sample Volume: 600 μl
  • Sample Type: Nasal- or oropharyngeal swab sample

 

DETECTABLE DNA PATHOGENS:SPECIFIC GENE TARGETS:
Methicillin-resistant Staphylococcus aureus (MRSA)SCCmec/orfX junction
Methicillin-sensitive Staphylococcus aureus (MSSA) mecA/ mecC, SA422

Making this happen, The MRSA/SA rapid test on Vivalytic by Bosch, a point of care platform brought to the market by Randox Laboratories. The Vivalytic system is a fully automated, cartridge-based platform capable of both Hi-Plex and Lo-Plex infectious disease testing. Each easy-to-use cartridge contains all necessary reagents, is fully-sealed to minimise risk and can be conveniently stored at room temperature.

The Vivalytic consolidates the full molecular workflow into a small benchtop platform, capable of extraction, PCR amplification and detection.  It follows an easy 4 step process from sample entry to results and with the gold standard PCR testing. With most up to date technology, the Vivalytic has wireless connectivity, with no peripherals required, making a unique space saving and hygienic solution. Handling and utilisation are simple and medical professionals require only minimal training.

Identification and Differentiation of Viral and Bacterial Respiratory Infection to Guide Antibiotic Stewardship

Identification and Differentiation of Viral and Bacterial Respiratory Infection to Guide Antibiotic Stewardship

 

The development of point-of-care testing is critical in the identification and differentiation between bacterial and viral respiratory infections. Defining the indications of infection to improve antibiotic stewardship, ensures that patients are protected from unnecessary antibiotic use and antibiotic resistance. It has been shown that particular protein biomarkers, such as myxovirus resistance protein (MxA) and C-reactive protein (CRP), differentiate infections between bacterial and viral. Using point-of-care platforms, such as Randox’s VeraSTAT, for detection of these protein biomarkers may provide more rapid and cost-effective discriminating tools.

The treatment of bacterial and viral infections can differ significantly, however people are often treated with empirical antibiotics due to a lack of paid and accurate testing. Although early intervention of infection is urgent, current diagnostic methods are either time intensive or inaccurate. The challenges clinicians are faced with in the differentiation of viral or bacterial respiratory infection can lead to delayed diagnosis, misappropriation of antibiotics and increased healthcare costs.

MxA protein has the potential to greatly enhance the rapid detection of viral respiratory infections as it increases significantly when there is actuate viral infection. CRP is the dominant acute phase protein often used to guide treatment of a bacterial infection or inflammation associated with tissue injury, inflammatory disorders, and associated diseases.

CRP & MxA together, allow clinicians to make appropriate decisions in supporting antimicrobial stewardship and guide the appropriate use of antibiotics, saving time performing unnecessary tests, providing unnecessary treatment which missing the opportunity to provide the right treatment in a timely manner.

The Randox VeraSTAT is a simple, accurate, portable point of care device which delivers rapid results via the use of patented cathodic electrochemiluminescence technology (C-ECL). Designed with the aim of offering users the next generation of rapid diagnosis, the VeraSTAT eliminates the requirement to send samples to a laboratory and instead returns results in as little as 6 minutes.

 

  • Eliminates delays in sending samples to the lab and facilitate immediate decision making at the point of care.
  • Lightweight, portable and convenient, the Randox VeraSTAT can be used in a variety of locations to deliver results as required, such as a GP surgery or Emergency Department.
  • Intuitive user interface guides the operator through the entire testing process.
  • All necessary reagents are conveniently included in each single use, sealed cassette with no preparation required. All necessary consumables are supplied with the kit.
  • The Randox VeraSTAT allows for results to be exported via Bluetooth connectivity.
  • Flexible test menu comprising of a range of immunoassay, protein, inflammatory, diabetes & infectious disease markers.

 

Novel testing approaches identifying the type of infection at the point of care are essential in accurately guiding appropriate antibiotic treatment. Although these tests can’t determine what type of viral or bacterial infection a patient has, it will determine whether the infection is viral or bacterial, further testing is then carried out to determine what type of pathogen the patient has via PCR – the gold standard. The ability to distinguish between viral and bacterial infections is the most effective guide for clinical decision making and is an innovative tool for antibiotic stewardship.
