QIAGEN and DiaSorin has announced the launch of the LIAISON® LymeDetect® Assay for markets accepting the CE mark, as an aid to detect early Lyme Borreliosis infection (Lyme) on LIAISON® analyzer systems.
Lyme is a tick-borne illness caused by the Borrelia burgdorferi bacterium species, with different types of manifestations in the early phase: early-localized rash (the typical Erythema Migrans) and early-disseminated forms, where people may develop a different kind of rash, remain asymptomatic or have quite non-specific symptoms such as fever, chills, headache, fatigue, muscle and joint aches.
If the early infection is left untreated, Borrelia burgdorferi might spread to joints, the heart and the nervous system becoming a chronic illness and evolving into severe complications. Late stage symptoms can include severe headaches and neck stiffness, facial palsy, arthritis with severe joint pain and swelling, intermittent pain in tendons, muscles, joints, and bones, heart palpitations or an irregular heartbeat (Lyme carditis), inflammation of the brain and spinal cord and pain.1 These long term effects may persist after a successful treatment course.
Recent publications2 estimate that the total number of yearly cases in Western Europe could be as high as 230,000.
The current diagnostic routine for early disseminated Lyme diagnosis uses serological testing for IgG and IgM antibodies detection (B cell response), followed by a confirmation using Western Blot in case of positivity or equivocal results.
In the early stages of the infection, however, results can be unsatisfactory because patients often get tested at the onset of the disease, when visible signs of the tick bite or the presence of the tick itself are detected, but before the appearance of antibodies (IgG or IgM) against the pathogen. An undetected Lyme disease presents an increased risk of developing into a severe chronic disease. This presents a significant untapped diagnostic need.
DiaSorin and QIAGEN have been collaborating to provide a solution to this diagnostic gap which significantly improves the sensitivity of testing in the early phase of Lyme borreliosis. The new LIAISON® LymeDetect® solution combines both humoral (detection of IgG and IgM antibodies) and cellular immunity through a specific interferon-gamma release assay, stimulated by specific Lyme peptides using QuantiFERON® LymeDetect® technology, providing significantly improved sensitivity and earlier detection of the infection.
In clinical studies, the LIAISON® LymeDetect® Assay showed, within 21 days from the first evidence of infection, a sensitivity of to 74% versus that of existing alternative methods (ca. 49%). Moreover, the LIAISON® LymeDetect® Assay also demonstrated a high diagnostic specificity of 100%.
By providing a tool which significantly increases the sensitivity in the early stages of the disease, the LIAISON® LymeDetect® could help physicians identify and treat the disease earlier, minimizing the risk of late and chronic manifestation, with benefits for patients and a significant healthcare cost reduction, mainly due to shorter hospitalization and long-term care for late disease treatment.
DiaSorin and QIAGEN worked together to co-develop the new LIAISON® LymeDetect®, an innovative solution for diagnosing Lyme disease, designed to be run on the LIAISON® XL and LIAISON® XS platforms. Under the development agreement, DiaSorin is responsible for commercialization of the new LIAISON® LymeDetect, while QIAGEN and DiaSorin are jointly responsible for development and production of the solution.
“QIAGEN believes in expanding and maximizing the value of our QuantiFERON portfolio, led by the gold-standard QuantiFERON TB Gold-Plus Assay that forms the foundation of our collaboration with DiaSorin and the joint global marketing of our solution for use on the LIAISON family of analyzers,” said Thierry Bernard, Chief Executive Officer of QIAGEN. “The fight against Lyme disease is increasingly critical given the risks and symptoms and estimates that the number of ticks carrying the disease is on the rise worldwide. For this collaboration, we are taking a new approach with DiaSorin that builds on our unique strengths, in particular our capabilities to develop and gain approval for novel QuantiFERON-based tests and DiaSorin’s expertise with its current portfolio of solutions for this disease. We are eager to see the benefits of this partnership in improving outcomes for patients suffering from a disease with often debilitating consequences.”
“We are very proud of this new milestone reached in partnership with QIAGEN, because we think it is going to be a game-changer in the Lyme disease diagnosis space and a milestone in our Value Based Care strategy,” commented Carlo Rosa, Chief Executive Officer of DiaSorin Group. “The collaboration between our companies leverages on their QuantiFERON technology and our extensive installed base of LIAISON family analyzers and is positioning us both as leaders in the T-cell response market with a unique franchise for laboratories looking for an efficient way to detect asymptomatic infections and risks that cannot be detected in all situations with standard diagnostic technologies. This new solution, together with our already validated Lyme disease tests, will strengthen our role as a company committed to find solutions for diagnosing a disease so prevalent in specific regions and so difficult to detect at an early stage that causes painful and long-lasting consequences in the lives of affected patients.”
QIAGEN’s QuantiFERON-TB Gold Plus for latent tuberculosis is registered in more than 75 countries in North America, Europe, Asia, Africa and Latin America. QIAGEN’s QuantiFERON-TB Gold (QFT) and QFT-Plus tests are the gold standard blood tests for latent TB, with faster, less labor-intensive and more accurate insights than the century-old tuberculin skin test. The test can be automated on DiaSorin LIAISON® platforms. The QuantiFERON Product portfolio also includes tests for SARS-CoV-2 T-Cell immune response, CMV and QuantiFERON Monitor used for transplant applications. LymeDetect® is the newest expansion to this portfolio leveraging innovative CD4/CD8 T cell technology to enable immune response detection.
