lapse rates, is central to improving outcomes. Historically, there have been no dynamic, quantifiable methods to track disease activity over time. This creates challenges in MS management and could lead to less-than-optimal utilization of disease-modifying therapies, which are essential for reducing disease activity, minimizing relapses, and slowing disease progression. Now, a new blood test has demonstrated potential for offering quantitative insights to enhance the care of MS patients and deliver a superior performance compared to the top-performing single-protein model. Octave Bioscience (Menlo Park, CA, USA; www.octavebio.com) has developed the Octave MSDA Test, which is the first and only multi-protein serum-based biomarker assay devised to quantitatively measure the disease activity of MS patients. This test can be used throughout a patient’s disease journey, enabling more informed clinical decisions for improved disease management. The Octave MSDA Test is part of the comprehensive Octave Precision Care Solution, which combines data from the test along with expanded imaging capabilities and clinical insights, providing a more comprehensive view of the patient. This solution equips the entire MS care ecosystem with the means to better gauge, monitor, and manage the disease. Octave has completed evaluating over 1,400 protein biomarkers using more than 3,000 patient samples. Advanced data science, machine learning, and feature extraction techniques were harnessed to select the top-performing and most pertinent 18 biomarkers for incorporation into a customized assay panel, developed using the Olink proteomics platform. These biomarkers were then integrated into an algorithm, generating four pathway scores that represent distinct disease processes in MS pathophysiology – immunomodulation, neuroinflammation, myelin biology, and neuroaxonal integrity. Additionally, the algorithm produces an overall disease activity score on a scale of 1.0 to 10.0. The Octave MSDA Test boasts numerous clinical applications throughout the care continuum. It aids in routine surveillance to better monitor disease activity, especially in patients with stable disease, and to track emerging or worsening symptoms. Furthermore, it can be used as an objective assessment of treatment response and tracks a patient’s disease activity level once a decision has been made with their clinician to scale back or discontinue their disease-modifying treatment. The Octave MSDA Test promotes shared decision-making between patients and their physicians while complementing standard radiographic imaging and clinical evaluation to offer more objective insights for enhanced MS care. In a recent study published in Clinical

Immunology, the test was clinically validated relative to radiographic and clinical markers of disease activity and outperformed the top-performing single protein model. Presently, the Octave MSDA Test is available for commercial use and is being routinely utilized in leading practices across the United States, as well as in pharmaceutical studies. “We are encouraged that these results validate the performance of the Octave MSDA Test and demonstrate its ability to quantitatively and objectively measure disease activity of patients with MS,” said Ferhan Qureshi, Vice President of Biomarker Product Development at Octave. “The test interrogates multiple biological pathways important in MS pathophysiology with a

Researchers at King Abdullah University of Science and Technology (KAUST, Saudi Arabia; www.kaust.edu.sa) have created a prototype sensor capable of measuring glucose levels in saliva. This innovation could eventually offer a simple, swift, and painless way for individuals to monitor their diabetes. The KAUST team devised a remarkably sensitive glucose detector built on a thin-film transistor. The transistor features thin layers of semiconductors, including indium oxide and zinc oxide, along with the enzyme glucose oxidase on top. When a saliva sample is applied to the sensor, the enzyme converts any glucose present into D-gluconolactone and hydrogen peroxide. The electrical oxidation of hydrogen peroxide generates electrons that enter the semiconductor layers and modify the current flowing through the semiconductors, a change that reflects the glucose concentration in the sample. The researchers evaluated their device using human saliva samples with varying glucose levels and analyzed saliva from fasting volunteers. The device proved to accurately measure a broad range of glucose concentrations in under a minute. Importantly, the sensor remained unaffected by other molecules in saliva, including sugar derivatives like fructose and sucrose.

Antimicrobial Resistance: New Insights into Evolution Call for Shifts in Testing Cont’d from cover

A research study published in the journal Nature Communications has offered novel insights into the development of antimicrobial resistance (AMR) in patients suffering from bacterial infections. This could lead to more effective preventative strategies against AMR infections in susceptible individuals. Contrary to the conventional belief that infection typically occurs due to a single strain of bacteria that develops resistance through new genetic mutations, the study suggests that patients often get co-infected by multiple clones of pathogens. In these cases, resistance arises from the selection of already resistant clones rather than new mutations. In the study led by the University of Oxford (Oxford, UK; www. ox.ac.uk), the researchers utilized an innovative technique to examine genetic alterations and antibiotic resistance in Pseudomonas aeruginosa, a common hospital-acquired bacterium, particularly among immunocompromised and severely ill individuals. Samples were taken from 35 patients in intensive care units across 12 European hospitals. Approximately two-thirds of the patients were found to be infected by a single strain of Pseudomonas, in some of which AMR developed due to new mutations, as traditionally believed. However, in a surprising revelation, one-third of patients were infected by multiple strains of the bacteria. It was observed that patients with mixed-strain infections exhibited a roughly 20% higher increase in resistance when exposed to antibiotic treatment compared to those with single-strain infections. The spike in resistance was primarily attributed to the selection of pre-existing resistant strains that already existed prior to antibiotic therapy. Interestingly, the study also found that such resistance could decline rapidly under certain conditions. When samples from single-strain and mixed-strain infections were cultured without antibiotics, the growth rate of AMR strains was slower compared to non-AMR strains. This supports the idea that AMR genes carry fitness trade-offs and are negatively selected when antibiotics are absent. This effect was more pronounced in mixed strain populations, suggesting that a diverse bacterial environment could contribute to resistance loss in the absence of antibiotics. The findings suggest that strategies focusing on controlling bacterial transmission among patients, such as improved sanitation and infection control measures, might be more effective against AMR compared to efforts to prevent new resistance mutations. This is particularly important in settings with a high infection rate, like immunocompromised individuals. Additionally, the study calls for a shift in clinical testing,

emphasizing the importance of considering pathogen strain diversity instead of assuming a singular strain during infection assessments. This approach could aid in making more accurate predictions about antibiotic treatment effectiveness and improve patient outcomes, similar to the use of diversity measurements in cancer cell populations to predict chemotherapy success. "The diagnostic methods employed for assessing antibiotic resistance in patient samples have undergone slow evolution over time, and our findings highlight the significance of developing new diagnostic approaches that facilitate the assessment of pathogen population diversity in patient samples," said Professor Craig Maclean, the lead researcher from the University of Oxford's Department of Biology.

New Breast Cancer Susceptibility Genes Identified enetic tests for breast cancer currently focus on a limited number of genes, including BRCA1, BRCA2, and PALB2, but this scope only accounts for a small part of the overall genetic risk for the disease. This has led researchers to believe that other risk-associated genes are yet to be discovered. Now, a large-scale international collaborative study has identified new genes linked to breast cancer that could eventually be included in tests to detect women at an elevated risk of the disease. The study led by researchers from Université Laval (Québec, Canada; www.ulaval.ca) and the University of Cambridge (Cambridge, UK; www.cam.ac.uk) has found evidence for at least four new breast cancer risk genes, and possibly more. These newly-discovered genes deepen medical understanding of the genetic risk factors for breast cancer and could improve risk prediction. By identifying women with a higher likelihood of developing the disease, there is potential for improving breast screening methods, risk reduction strategies, and clinical management practices. In addition, the discovery of these new genes sheds light on the biological processes that lead to cancer development,

possibly paving the way for new treatment options. The study, which was published on August 17, 2023 in the journal Nature Genetics, utilized extensive genetic data. The research included an examination of genetic changes across all genes in a sample of 26,000 women with breast cancer and 217,000 without the disease, encompassing participants from eight countries in Europe and Asia. The goal is to incorporate this newfound information into a comprehensive risk prediction tool that health professionals worldwide currently use. However, before these discoveries can be implemented

in a clinical environment, the researchers have recognized the need to validate the results with further datasets for which the team is presently undertaking a large-scale international effort. "Improving genetic counseling for high-risk women will promote shared decision-making regarding risk reduction strategies, screening and determination of treatment options," said Professor Jacques Simard of Université Laval. “Although most of the variants identified in these new genes are rare, the risks can be significant for women who carry them. For example, alterations in one of the new genes, MAP3K1, appear to give rise to a particularly high risk of breast cancer.”

Bacteria Engineered to Detect Tumor DNA Could Seek and Destroy Gastrointestinal and Other Cancers umors release their DNA into their surrounding environment, a phenomenon known as shedding. While various technologies can analyze purified DNA in laboratory settings, they fall short in detecting DNA where it is released. Although bacteria have been engineered for diverse diagnostic and therapeutic tasks, they cannot recognize specific DNA sequences and mutations outside of cells. Now, researchers have engineered bacteria that can identify tumor DNA in a live organism. This innovation, which successfully detected cancer in the colons of mice, has the potential for the creation of new biosensors to identify infections, cancers, and other diseases. Under the new “Cellular Assay for Targeted CRISPR-discriminated Horizontal gene transfer,” or “CATCH,” strategy, scientists from the University of California San Diego (La Jolla, CA, USA; www.ucsd.edu) used CRISPR technology to engineer bacteria capable of assessing free-floating DNA sequences on a genomic level. The concept involved repurpos-

T

ing bacteria that are naturally present in the colon as biosensors, capable of detecting DNA released from colorectal tumors. The focus was on Acinetobacter baylyi, a bacterium in which the essential components for both acquiring DNA and utilizing CRISPR for analysis were identified. The researchers proceeded to design, construct, and assess Acinetobacter baylyi as a sensor for detecting DNA from the KRAS gene, which is frequently mutated in various cancers. They programmed the bacterium with a CRISPR system to differentiate between mutant and normal (non-mutated) variants of the KRAS gene. Consequently, only bacteria that had incorporated mutant KRAS forms, as present in precancerous growths and cancers, would survive to indicate or respond to the disease. This research builds upon the concept of horizontal gene transfer, a method by which genetic material is exchanged among organisms in a manner distinct from traditional genetic inheritance. While horizontal gene

transfer is commonly observed between bacteria, the researchers successfully adapted this concept from mammalian tumors and human cells into bacteria. The researchers are presently refining their bacteria-based biosensor strategy, exploring new circuits and various bacterial species for detecting and treating human cancers and infections. Researchers believe that in the future, cellular interventions will surpass traditional medicinal approaches. A living bacterium capable of detecting DNA within the gastrointestinal tract holds remarkable potential as a sentinel for identifying and combating gastrointestinal cancers, along with numerous other malignancies. “There is so much potential to engineer bacteria to prevent colorectal cancer, a tumor that is immersed in a stream of bacteria, that could help, or hinder, its progression,” said researcher Susan Woods. The research was presented in a study published on August 11, 2023 in the journal Science. LabMedica International October/2023

microscopy, rapid diagnostic tests, and PCR. Nevertheless, the established benchmark for malaria diagnosis is manual light microscopy, where a specialist examines blood samples under a microscope to verify the presence of malaria parasites. However, the result accuracy is heavily dependent on the expertise of the microscopist and can be affected by fatigue caused by workloads among the professionals conducting the tests. Due to the demanding nature of traditional diagnosis and the high workload, an international team of researchers undertook an investigation into the feasibility of employing a novel system that combines an automated scanning microscope with artificial intelligence (AI) for clinical diagnosis. The results indicated that this system identified malaria parasites with almost the same accuracy as experienced microscopists following standard diagnostic procedures. This advancement holds the potential to ease the burden of microscopists and increase the manageable patient caseload.

Researchers at The Hospital for Tropical Diseases at UCLH (London, UK; www.uclh. nhs.uk) tested a fully automated malaria diagnostic system comprising both hardware and software components. The automated microscopy platform scans blood samples, and algorithms for malaria detection process the images to detect the presence and quantity of parasites. The researchers analyzed more than 1,200 blood samples from travelers who had returned to the UK from regions where malaria is prevalent. The study evaluated the accuracy of the AI-microscope system in a true clinical setting under ideal conditions. The researchers compared the results obtained from both manual light microscopy and the AI-microscope system. Manually, 113 samples were identified as having malaria parasites, whereas the AI system accurately detected 99 positive samples, resulting in an 88% accuracy rate. Despite this commendable accuracy rate, the automated system also produced false positives, indicating 122 samples as positive when they were not, potentially

leading to unnecessary administration of anti-malarial drugs to patients. “At an 88% diagnostic accuracy rate relative to microscopists, the AI system identified malaria parasites almost, though not quite, as well as experts,” said Dr. Roxanne ReesChanner, a researcher at The Hospital for Tropical Diseases at UCLH. “This level of performance in a clinical setting is a major achievement for AI algorithms targeting malaria. It indicates that the system can indeed be a clinically useful tool for malaria diagnosis in appropriate settings.”

New Method Aligns Data from Tissue Slices Virtually to Expand Possibilities for 3D Analysis hen it comes to studying biological tissue, whether from a patient or an animal, a common approach involves surgically removing a portion of the affected tissue for analysis. In laboratories across the globe, technicians meticulously slice the extracted tissue into thin sections, which are then examined under a microscope or subjected to tests that detect specific molecules. These molecular clues can aid in diagnosing conditions, guiding treatments, or even gauging the effectiveness of drugs. However, the process of analyzing each slice is resource-intensive in terms of time, money, and computational capacity.

Consequently, researchers and medical professionals are often constrained to studying only a limited number of slices from various parts of the tissue. Adding to the complexity, the act of cutting, processing, and analyzing tissue slices within a lab environment causes them to undergo physical distortions. As a result, accurately understanding how these slices align and fit into the three-dimensional structure of the original tissue becomes challenging. Now, a new method revolutionizes the ability to comprehend the three-dimensional composition of tissues, including tumors or other tissue using data from just a few slices, thus allowing for a

much deeper understanding of biological tissue samples. The new method, named Gaussian Process Spatial Alignment (GPSA) which has been developed by researchers at Gladstone Institutes (San Francisco, CA, USA; www.gladstone. org) has a scope extending beyond tumors, encompassing a wide array of tissues and data derived from tissue slices. This innovative method leverages a two-layer Gaussian process. In the first layer, it aligns the warped two-dimensional tissue slice onto a three-dimensional tissue model. The second layer attributes data collected from the slice, such as Cont’d on page 11 LabMedica International October/2023

Method Eliminates Renal Biopsies

of SLE patients who develop renal symptoms will progress to end-stage kidney disease within a decade. The current standard method for diagnosing LN is through a renal biopsy, a painful procedure involving the extraction and examination of kidney tissues. Unfortunately, this method has significant drawbacks, including low agreement among pathologists in determining classes and pathology indices. This inconsistency can result in misclassification of LN, leading to incorrect treatment and poor patient outcomes. Furthermore, renal biopsies only yield limited tissue samples, restricting the type and scope of analysis performed on a sample. A promising breakthrough has emerged from researchers at the University of Houston (Houston, TX, USA; www.uh.edu), who have pioneered the use of imaging mass cytometry (IMC) to study the kidneys of SLE patients and diagnose LN. IMC offers substantial advantages over traditional methods, providing a much more comprehensive analysis of the affected tissue. Unlike conventional approaches that examine only 1-3 distinct proteins within a specific tissue, IMC can detect the presence of up to 37 different proteins simultaneously. The use

of IMC is often combined with machine learning algorithms to characterize the cellular composition of the human kidney, differentiate cell types, and identify novel markers for disease. One of the major benefits of IMC is its ability to precisely pinpoint locations of tissues for more detailed investigation. During a study involving 21 patients, researchers utilizing IMC discovered both increased and decreased disease markers indicative of renal disease. Additionally, they found that glomeruli (an intricate network of blood vessels serving as the kidneys’ cleaning system) might be enlarged in some LN patients. These findings were published in a recent study in the journal Clinical Immunology. “Decreased expression of epithelial markers along with an increased expression of mesenchymal markers, also termed epithelial to mesenchymal plasticity (EMP) have been reported in kidney biopsies from patients with renal diseases, including LN,” said Chandra Mohan, Hugh Roy and Lillie Cranz Cullen Endowed Professor of biomedical engineering. “It is very likely that the parietal epithelial cells encircling the glomeruli may be an additional site of EMP in proliferative LN, though this needs to be verified using additional markers.

EMP could certainly affect additional cells in LN kidneys, but this needs to be systematically investigated.”

activated genes, to each point in the three-dimensional model. This intelligent approach effectively reverses the warping effect, resulting in a precise alignment of the slices. During this process, the GPSA model extrapolates data to fill the gaps between slices, generating a comprehensive three-dimensional “atlas” of the tissue. A key advantage of GPSA is its versatility. Researchers can construct tissue atlases using

data from slices of varying sizes, generated by diverse technologies, and captured at different scales and resolutions. Unlike previous techniques that demanded a predefined three-dimensional framework, GPSA derives this framework solely from the two-dimensional slices when an initial framework isn’t available. Additionally, GPSA has the capability to merge multiple types of tissue-slice data, such as genetic activity and cellular structure, into a unified atlas. Furthermore, when applied

11

to slices taken from the same tissue at different time points, GPSA can generate atlases that predict how each location within the tissue evolves over time. This feature could deepen our insights into aging, disease progression, and the development of different tissues within growing organisms. Presently, researchers are engaged in further analyses to further demonstrate the tool’s flexibility. For instance, they have devised an approach that budget-conscious labs can use to determine the minimum number of tissue slices required and the precise cutting locations needed for GPSA to build an informative tissue atlas. “Say you have four slices from different locations in a person’s breast cancer tumor, and for every point on each slice you know which of 20,000 genes are turned on or off,” said Gladstone Senior Investigator Barbara Engelhardt, PhD, senior author of the study. “GPSA creates a fully query-able 3D atlas where, for any single ‘x, y, z’ coordinate, for any of the 20,000 genes, we can dive in and ask: What genes are on and off at this position in the tumor? And how certain are we in this estimate?” Image: Barbara Engelhardt and her colleagues have developed a new tool to align data from tissue slices virtually, expanding possibilities for 3D analysis (Photo credit: Michael Short/Gladstone Institutes) LINKXPRESS COM

Rapid Sepsis Test Uses Magnetic Nanoparticles to Detect Bacterial Pathogens hen it comes to life-threatening blood poisoning caused by staphylococcus bacteria, quick identification of the bacteria in the bloodstream is vital to begin life-saving treatment. This urgency stems from the fact that staphylococcal sepsis results in fatality for up to 40% of cases. The infection, triggered by spherical bacteria, might initially manifest as a local skin ailment or pneumonia. However, when staphylococci infiltrate the bloodstream during sepsis, severe complications can emerge. In such critical scenarios, prompt identification of pathogens and selection of suitable antibiotics are vital. This is especially crucial as Staphylococcus aureus strains can exhibit resistance to multiple antibiotics. Researchers have now developed “sepsis sensors” using magnetic nanoparticles that enable rapid detection of bacterial pathogens and identification of appropriate antibiotic candidates. Researchers at Empa (Dübendorf, Switzerland; www.empa.ch), along with their colleagues from ETH Zurich (Zürich, Switzerland; www.ethz.ch), looked for a way to bypass the lengthy intermediate step of first cultivating the bacteria in a blood sample for a diagnostic procedure. They developed a method utilizing magnetic nanoparticles that are capable of binding to staphylococci. Consequently, these bacteria can be identified through the application of a magnetic field. Subsequently, antibiotic sensitivity is assessed using a chemiluminescence technique. If antibiotic-resistant bacteria are present in the sample, it emits light. Conversely, if the bacteria can be eradicated with antibiotics, the reaction vessel remains dark. Another problematic bacterial entity is Pseudomonas aeruginosa, a rod-shaped bacterium capable of causing various illnesses, including urinary tract infections via catheterization during hospital stays. Such infections can develop into sepsis, and these pathogens are often resistant to numerous antibiotics. In such cases, magnetic nanoparticles offer the distinct advantage of versatility. The approach can be customized for different bacteria types, similar to a modular system. This adaptability enabled the researchers to design a rapid “sepsis sensor” leveraging magnetic nanoparticles. In samples containing synthetic urine, this method reliably identified bacterial species and gauged potential antibiotic resistance through chemiluminescence reactions. So far, the researchers have assessed their magnetic nanoparticle toolkit for sepsis and urinary tract infections using laboratory samples. In the coming

phase, the team plans to validate the sepsis tests alongside their clinical partners by analyzing patient samples. “All in all, the sepsis test takes around three hours – compared to several days for a classic cultivation of bacterial cultures,” said Empa researcher Fei Pan.

Blood Test Identifies Pregnant Women at Higher Risk of Preeclampsia reeclampsia, a serious pregnancy complication affecting 1 in 40 pregnant women, is characterized by elevated blood pressure. Left untreated, it can lead to organ damage and, in rare instances, maternal or fetal death. As the exact cause remains uncertain, identifying high-risk patients is complex. Now, researchers have discovered that DNA analysis can identify women at higher risk of developing severe preeclampsia during later pregnancy stages. Detecting high-risk patients early will allow for administering preventive medication, significantly reducing the risk of severe preeclampsia. Around 1 in 8 cases involve early-onset preeclampsia, manifesting between 20 and 34 weeks of pregnancy. Preterm births, often induced due to preeclampsia, require neonatal intensive care and can lead to serious complications. Promptly identifying women with an elevated risk of early preeclampsia is essential for initiating appropriate and preventive treat-

New STI Testing Guidelines to Render Low-Cost POC Diagnostics More Accessible Cont’d from cover

growing concern over treatment-resistant strains of gonorrhea, particularly a Neisseria gonorrhea clone resistant to ceftriaxone, found in several countries. Diagnosing STIs in low- and middle-income countries is further complicated due to limited access to diagnostic tests. To tackle these challenges, the World Health Organization (WHO, Geneva, Switzerland; www.who.int) has shared its latest guidance on sexually transmitted infections (STIs) at the STI & HIV 2023 World Congress which took place in Chicago, US, on 24-27 July 2023. Given the rising STI numbers, WHO has emphasized the need for improved testing and diagnostic services. During the congress, WHO shared its latest research on STIs and antibiotic resistance in gonorrhea. The new guidance includes target product profiles (TPPs) for point-of-care diagnostic technologies for diagnosing syphilis (treponema pallidum), Chlamydia trachomatis, Neisseria gonorrhea, and Trichomonas vaginalis, which intend to aid the development of quality STI diagnostics. TPPs can ensure that products are developed and produced to fulfill the clinical needs of populations at risk and are “fit-for-use” – in other words, that they are safe, effective, and adapted to the use environment. Point-of-care tests can reduce healthcare costs, minimize waiting times, expedite initiation of and enhance the accuracy of treatment, and improve patient follow-up. The new fourth edition of the Laboratory and Point-of-Care Diagnostic Testing Guide for STIs, including HIV, offers the latest details on STI isolation, detection, and diagnosis. The guide has been expanded to include information about molecular testing, rapid on-the-spot tests, and

ment, reducing both preeclampsia and potential premature birth risks. Current screening methods are often complex, time-consuming, and unreliable. In order to understand the pivotal role of the placenta, researchers from KU Leuven (Leuven, Belgium; www.kuleuven.be) compared placental DNA in 498 women with and without early preeclampsia. Normal pregnancy brings changes in placental DNA structure through DNA methylation. However, the researchers found that women developing early preeclampsia exhibited a distinct DNA methylation pattern. While the cause of this difference remains unknown, it can allow physicians to identify high-risk women and initiate treatment before symptoms emerge. The new test offers a significant advantage: it can be conducted using DNA from a simple blood sample taken around the 12th week of pregnancy. Given that blood samples are routinely taken for non-invasive prenatal testing (NIPT) to identify fetal chromosomal abnormalities, additional placental samples or cells are not necessary. "In time, our analysis can be carried out simultaneously with the NIPT test,” said Professor Bernard Thienpont who led the research. “But first, we will focus on implementing our new method on a larger scale, optimizing and validating it. We also want to investigate whether certain women would benefit more from preventive screening, for example, in the case of a first pregnancy."

A new product on the Diagnostics Landscape for Sexually Transmitted Infections (STIs) highlights diagnostics available to support scale-up of screening for syphilis, chlamydia, gonorrhea, trichomoniasis, mycoplasma, and human papillomavirus (HPV), specifically catering to the rising demand for tests in low-to-middle income countries. “New models of STIs services need to be resilient and adaptive to current and future threats”, said Dr. Meg Doherty, Director of WHO’s Global HIV, Hepatitis and Sexually Transmitted Infections Programs. “Recent scientific advances in STIs treatment and technologies, and innovative service delivery methods, provide an important opportunity to end STIs as a public health concern by 2030. However, large variations in investment, maturity and performance of STI surveillance systems between countries continues to be a challenge”.

When irradiated with visible light, these nanotubes emit near-infrared light, a spectrum invisible to the human eye but ideal for optical applications due to the significant reduction of other signals within this range. Previously, the team had successfully manipulated the nanotubes’ fluorescence to detect vital biomolecules. Their latest effort involved customizing carbon sensors for easy detection of various target molecules. This breakthrough was achieved with the help of DNA structures with guanine quantum defects. This process involved linking DNA

Rapid Blood Test Detects and Distinguishes 18 Infectious or Inflammatory Diseases Cont’d from cover

tance and an uptick in drug-resistant infections. Traditional diagnostic tests typically focus on identifying specific pathogens, like SARS-CoV-2, HIV, or Influenza through lateral flow tests (LFTs), or bacteria and yeast through blood cultures. However, these methods have their limitations. LFTs can only confirm or deny a specific cause, while blood cultures may take up to 72 hours or more for reliable results. But now, a promising blood test that can rapidly diagnose the cause of a child’s illness is being hailed as ‘transformative’. An international team, led by researchers at Imperial College London (London, UK; www.imperial.ac.uk) has developed and validated a diagnostic method that can simultaneously detect and differentiate between 18 infectious or inflammatory diseases, such as group B Streptococcus (GBS), respiratory syncytial virus (RSV), and tuberculosis. Unlike current tests that can take hours, days, or even weeks, this approach is designed to yield results in under an hour. The innovative test uses a single blood sample to diagnose the cause of fever by recognizing specific patterns of genes that are activated or deactivated by the body in response to particular illnesses. The finding builds on over a decade of research that seeks to detect and diagnose illnesses through gene expression patterns. In the latest study that was published on August 18, 2023 in Cell Press Med, the researchers analyzed the pattern of gene expression in blood in response to various infections and inflammatory conditions. They collected data from thousands of patients, including over 1000 children suffering from 18 infectious or inflammatory diseases, to identify the key genes that were switched ‘on’ or ‘off’. Utilizing machine learning, the team identified a panel of 161 genes for 18 conditions that corresponded to specific disease areas and pathogens. To further validate the panel, the researchers assessed a group of 411 pediatric patients hospitalized with sepsis or severe infections. Gene expression from blood analysis was compared to diagnoses made using existing clinical methods. As introducing new diagnostic tests in a clinical setting can have severe consequences if misdiagnoses occur, the team applied a ‘cost-sensitive’ measure, consulting a panel of five clinical experts to ensure the test could accurately avoid misdiagnoses where the consequences would be most significant. While still in the proof-of-concept stage, the researchers are hopeful that a diagnostic test centered on patients’ gene expression could markedly enhance the diagnosis of childhood diseases. This breakthrough could minimize delayed or missed diagnoses and make a substantial difference in healthcare, especially in regions with limited resources. “This body of work has enabled us to identify the molecular signature of a wide range of diseases based on 161 genes, out of thousands of genes in the human genome. By distinguishing between many diseases at the same time within the same test, we have developed a more comprehensive and accurate model that aligns with the way clinicians think about diagnosis,” said Dr. Myrsini Kaforou, Senior Lecturer within Imperial’s Department of Infectious Disease. “A future diagnostic test based on this approach could help provide the right treatment, to the right patient, at the right time, while optimizing antibiotic use, and reducing lengthy time to diagnosis for inflammatory diseases.”

Simple Mouth Rinse Test Provides Early Cardiovascular Disease Warning Signs eriodontitis, a widespread oral health issue involving infected gums, has been linked to cardiovascular disease. In a new study, scientists explored the inflammation leading to periodontitis and examined whether the levels of white blood cells (a sign of gum inflammation) in the saliva of healthy adults could signal potential cardiovascular issues. Specifically, they looked at whether high levels of these cells correlated with compromised flow-mediated dilation, an early sign of arterial problems. Scientists at Mount Royal University (Calgary, AB, Canada; www.mtroyal.ca) set out to investigate the link among young adults without any known periodontal problems to see if even minor levels of oral inflammation might have clinical significance for heart health. They selected two measures, pulse-wave velocity (to gauge artery stiffness) and flow-mediated dilation (to assess how well arteries expand to allow increased blood flow), as key indicators of cardiovascular risk. Both of these measurements directly relate to arterial health, and issues with

P

either can increase the risk of heart disease. The study involved 28 non-smoking participants aged 18 to 30, with no underlying health conditions, medications that might affect cardiovascular risk, or history of periodontal disease. Before visiting the laboratory, they were instructed to fast for six hours, although water intake was allowed. Upon arrival, they rinsed their mouths with water, followed by saline, which was then collected for analysis. Participants subsequently underwent an electrocardiogram while lying down, and remained in that position for additional tests, including blood pressure, flow-mediated dilation, and pulsewave velocity measurements. The findings revealed that high levels of white blood cells in the saliva were significantly linked to poor flow-mediated dilation, indicating a heightened risk of cardiovascular disease in these individuals. Interestingly, there was no connection between white blood cells and pulse-wave velocity, suggesting that the long-term effects on artery health were

not yet evident. Scientists have proposed that the inflammation from the mouth, possibly seeping into the vascular system, could affect the arteries’ ability to produce nitric oxide, which aids in responding to changes in blood flow. Elevated levels of white blood cells might further exacerbate this vascular dysfunction, although the levels detected in the study participants are generally not seen as clinically significant, indicating that even minor inflammation could have broader health implications. “We are starting to see more relationships between oral health and risk of cardiovascular disease,” said Ker-Yung Hong, first author of the study. “If we are seeing that oral health may have an impact on the risk of developing cardiovascular disease even in young healthy individuals, this holistic approach can be implemented earlier on.” “The mouth rinse test could be used at your annual checkup at the family doctors or the dentist,” said Dr. Michael Glogauer, a co-author of the study. “It is easy to implement as an oral inflammation measuring tool in any clinic.”

MESSAGE FROM THE PRESIDENT By Khosrow Adeli • President, IFCC

M

y warmest greetings to everyone at IFCC. I hope you all are enjoying the arrival of the Fall season. To start, I am delighted to inform you that the IFCC Organization is experiencing significant growth in its membership base. We have received applications from several new societies and countries seeking to become full or affiliate members, and we have welcomed numerous new corporate members in just the past few months. Pending ratification by the IFCC Council, we anticipate having 98 national societies as full members, more than 20 affiliate members, and 58 corporate members. This remarkable achievement breaks all previous records across all membership categories, underscoring the heightened visibility, influence, and global reach of the IFCC organization. Later this year, we will be publishing a special feature article in the eNews, highlighting all the new IFCC national societies, affiliates, and corporate members that have joined IFCC over the past three years. Additionally, there is a growing interest in IFCC membership from societies and entities in various specialties within laboratory medicine, extending beyond clinical chemistry. The IFCC Executive Board is enthusiastic about recommending an expansion of the IFCC’s membership scope, aiming to encourage participation from all areas of clinical laboratory diagnostics and clinical laboratory medicine. To align with this vision, we will be proposing amendments to the IFCC statutes, facilitating the inclusion of other specialties within the IFCC organization. Furthermore, the IFCC Executive Board is advocating for changes in the election process for Executive Board members to foster a more inclusive opportunity for individuals within the IFCC community to contribute to the board. The proposed amendments suggest that no individual should serve in the same position on the Executive Board for more than six years in total. Additionally, individuals cannot be nominated for more than one position in the same year or election cycle. Stay tuned for forthcoming updates! A ballot will be initiated, and all IFCC Full Member Societies will be invited to vote on the proposed revisions to the IFCC statutes, ensuring the continued growth and success of the IFCC Organization. I’m also thrilled to announce the formal launch of the new IFCC initiative on Laboratory Medicine Practice Guidelines. The IFCC Executive Board has granted approval for an innovative program aimed at encouraging IFCC functional units, including committees, taskforces, and working groups, to create and share best practice recommendations and guidelines across all facets of clinical laboratory medicine. This program is dedicated to facilitating the implementation of these recommendations in clinical laboratories worldwide. Under this program’s umbrella, the IFCC will develop various types of guidance documents, encompassing best practice recommendations, position papers, and comprehensive evidence-based and graded practice guidelines. These documents will be made widely and freely available, serving as valuable resources for laboratory professionals. Their purpose is to provide guidance, establish standards, and promote best practices within the field of laboratory medicine. Undoubtedly, these resources will contribute significantly to enhancing the quality of laboratory practices worldwide, with a particular focus on benefiting developing countries. To oversee and drive this program forward, we

Blood-Based Molecular Cancer Test Delivers Unsurpassed Accuracy and Specificity Levels he absence of an accurate blood biomarker in neuroendocrine tumor (NET) disease has hampered its effective management. The progress made in genomic medicine and the emergence of molecular biomarkers have paved the way for the adoption of liquid biopsy as a solution to allow for real-time management. Now, a blood-based neuroendocrine cancer diagnostic test can be used to help diagnose, recommend treatment, and then monitor progress for NET or neuroendocrine neoplasia (NEN) patients in real time. The NETest from Wren Laboratories (Branford, CT, USA; www. wrenlaboratories.com) assesses mRNA gene expression analysis to diagnose NETs. By focusing on mRNA, Wren achieves real-time evaluation of the disease state in NET or NEN patients through the interpretation of molecular signals released by cells related to neuroendocrine cancer activity found in a blood sample. The rapid and non-invasive liquid biopsy test enables results to be shared within 48 hours of receiving a blood sample. Upon arrival of the sample at Wren’s CAP and CLIA-certified laboratory, a quantitative polymerase chain reaction (qPCR) technique is employed to quantify the expression levels of 51 genes linked to neuroendocrine cancer. Subsequently, Wren employs multianalyte algorithmic analyses (MAAA) to calculate the likelihood of a patient having a NET or NEN. The resultant probability or risk score is then made available. The NETest outperforms any other available testing method in terms of sensitivity, specificity, and accuracy. It surpasses other NET diagnostics in robustness, boasting a remarkable 98% sensitivity that translates to minimal false negative results. It also exhibits an 86% accuracy in determining disease status (distinguishing between stable and progressive disease), a level of precision unmatched by other diagnostic methods. The results from the NETest offer insights into the tumor’s state, the presence of residual disease, and the potential for recurrence. The NETest demonstrates an impressive 99% accuracy in diagnosing post-treatment recurrences. Due to its exceptional accuracy in recurrence determination, the test reduces the need for imaging in nearbvly half of the patients, thereby mitigating radiation exposure. Furthermore, it assesses the tumor’s response to treatment. This comprehensive information aids oncologists and patients in enhancing treatment management and monitoring, facilitating swift detection

of disease recurrence. Additionally, Wren offers a companion prognostic tool to the NETest, referred to as PPQ, designed to evaluate the efficacy of peptide receptor radionuclide therapy (PRRT). The PPQ exhibits 94% accuracy in measuring the response to PRRT, far surpassing current predictive diagnostic methods such as somatostatin receptor expression and morphological imaging or chromogranin A (CgA) measurement. “Our NETest uses the cellular messaging system of the human body mRNA to detect tumor activity in the bloodstream, often before a tumor can be seen,” said Mark Kidd, Ph.D., laboratory and scientific director. “As the NETest panel includes 51 genes, we employ machine learning, also called AI, to analyze this incredibly dense molecular information about a patient’s tumor status.” “NETest puts patients in the best position possible to understand their disease and, specifically, how they are responding to treatment,” added Dan Buck, general manager. “This blood-based assay provides invaluable information delivered in a simple manner that helps oncologists and patients better understand where they are in their cancer journey.”

MEDICA 2023 to Host Laboratory Medicine Forum his year, the MEDICA LABMED FORUM will once again be a part of the international medical trade fair MEDICA (Düsseldorf, Germany; www.medica-tradefair.com) scheduled for 13-16 November 2023. The forum aims to cover a wide range of topics including cancer, heart diseases, infections, new anti-bacterial substances, and the role of digital technology and artificial intelligence (AI) in medicine. Over the years, the forum has gained significant attention as an integral part of the trade fair. Despite the complexity of the subjects for discussion, all presentations have been designed to be concise, clear, and understandable, and can be continued further in panel discussions. The inaugural day of MEDICA will dive into two particularly controversial subjects that are stirring up the laboratory medicine community: the “In-Vitro Diagnostics Regulation” (IVDR) and its implications for smaller IVD companies and specialized labs, as well as the growing role of AI with its potential and pitfalls. There will be an in-depth discussion on how to navigate the challenges brought about by new EU guidelines for diagnostic test quality assurance. This will be followed by an engaging discussion on how AI technologies, such as machine learning, are poised to transform lab work, particularly in automating the evaluation of microscopic images and complex data, like those used in leukemia diagnosis. The second day will focus on a discussion of groundbreaking advancements in the fields of oncology and cardiology. Recent research has highlighted the powerful diagnostic capabilities of blood tests in cancer treatment and management. Circulating tumor cells and nucleic acids, for example, are emerging as secondary but vital methods, providing new angles beyond traditional tissue examinations in oncology. Meanwhile, molecular diagnostic tests are reshaping cardiology, offering enhanced risk assessments for arteriosclerotic cardiovascular diseases. Additionally, genetic tests are gaining significance in the treatment of congenital heart defects, and new concepts like thromboinflammation are coming into play. The third day of the Forum is traditionally allocated to the next scientific generation in the field of laboratory medicine. Every year, young participants are invited to report on their current research and give an outlook on the future of the scientific field. The leitmotif for 2023 is “data sciences,” which captivates young minds, particularly due to the intelligent analysis of huge lab data sets. Presentation subjects will range from AI-enabled image evaluations to the analysis of complex lab data and automated generation of diagnostic reports. The discussions will also include the subject of practical applications in healthcare settings and the diagnostics industry. The final day of the MEDICA LABMED FORUM will kick off with an overview of diagnostic techniques that significantly cut down the time required to detect pathogens, thus allowing timely and effective treatment strategies. There will be a special focus on the rapid identification of the bacteria causing sepsis and targeted antibiotic usage. Moving beyond traditional antibiotic treatments, innovative ways to combat resistance will be explored. This includes discussions on alternative approaches like using small molecules against bacterial toxins or exploring phage therapy. To wrap up the event, there will be a deep dive into “Next Generation Sequencing” (NGS) and bioinformatics, with a spotlight on characterizing the microbiomes of newborns, a notably vulnerable patient group. Another traditional feature of MEDICA is the forward-looking presentations related to future trends in

diagnostics and life sciences, with a special focus this year on infectious diseases and antibiotic resistance, recognized as an escalating health crisis. The forum has steadily grown over the years, with last year’s MEDICA and its parallel event COMPAMED drawing a crowd of over 80,000 professionals, 75% of whom were from international backgrounds.
