Scientists Developing “Game-Changing” Test to Diagnose Parkinson’s Based on Compounds Found on Skin
Results published on March 11, 2021, show it's possible to spot Parkinson’s Disease supported compounds found on the surface of the skin. The findings offer hope that a pioneering new test might be developed to diagnose the degenerative condition through an easy and painless skin swab.
Scientists at The University of Manchester have developed a way that works by analyzing compounds found in sebum — the oily substance that coats and protects the skin — and identifying changes in people with Parkinson’s Disease. Sebum is rich in lipid-like molecules and is one among the lesser-studied biological fluids within the diagnosis of the condition. People with Parkinson’s may produce more sebum than normal — a condition referred to as seborrhoea.
The research has been funded by charities Parkinson’s the united kingdom and therefore the Michael J. Fox Foundation also because of the University of Manchester Innovation Factory. The work was originally funded following observation by Joy Milne, whose husband was diagnosed with Parkinson’s at the age of 45. Working with Dr. Tilo Kunath at the University of Edinburgh, Joy demonstrated a fantastic ability to differentiate a particular Parkinson’s odor in individuals using her sense of smell, even before symptoms emerge in those affected.
The team, led by Professor Perdita Barran, The University of Manchester, and therefore the clinical lead Professor Monty Silverdale at Salford Royal Foundation Trust, recruited 500 people with and without Parkinson’s. Samples of sebum were taken from their upper backs for analysis. Using different mass spectrometry methods, 10 chemical compounds in sebum were identified which are elevated or reduced in people with Parkinson’s. this enables scientists to differentiate people with Parkinson’s with 85 percent accuracy.

The team confirmed their earlier findings published in ACS Central Science that the volatile compounds on the skin are often wont to diagnose the condition, increasing the number of individuals sampled and including participants from the Netherlands, also because of the UK.
In a new study published today in Nature Communications, high-resolution mass spectrometry was wont to profile the complex chemical signature within the sebum of individuals with Parkinson’s and show subtle but fundamental changes because the condition progresses. Detailed analysis showed changes in people with Parkinson’s in lipid (fat) processing and mitochondria. Problems with mitochondria — the small energy-producing batteries that power cells — are one among the hallmarks of Parkinson’s.
This means this ‘world first’ testing strategy isn't only useful in diagnosing Parkinson’s but also in monitoring the event of the condition. The skin swab could provide an incredibly important new tool in clinical trials helping researchers measure whether new, experimental treatments can slow, stop or reverse the progression of Parkinson’s.
The study unveiled novel diagnostic sebum-based biomarkers for Parkinson’s provides insight into the understanding of how the condition develops and links lipid dysregulation to altered mitochondrial function.
These promising results published today could lead to a definitive test to diagnose Parkinson’s accurately, speedily, and cost-effectively. The team is now seeking funding to further develop the test and explore the potential for using the test to ‘stratify’ patients.
Working with the University of Manchester Innovation Factory, the team has patents filed for his or her diagnostic techniques and is getting to create a spin-out company to commercialize the new tests. they're also working to use this approach to develop tests for COVID-19 as shown in research last week in EClinical Medicine also as other conditions and are actively seeking investors curious about supporting the drive to bring this technology to plug.
Professor Perdita Barran, Professor of Mass Spectrometry at The University of Manchester, said: “We believe that our results are a particularly encouraging step towards tests that would be wont to help diagnose and monitor Parkinson’s.
“Not only is that the test quick, simple, and painless but it should even be extremely cost-effective because it uses existing technology that's already widely available.
“We are now looking to require our findings forwards to refine the test to enhance accuracy even further and to require steps towards making this a test which will be utilized in the NHS and to develop more precise diagnostics and better treatment for this debilitating condition.”
Parkinson’s tends to develop gradually and it's going to be many months, even years before the symptoms become obvious enough for a private to go to their GP. A DaTscan is often wont to help specialists confirm the loss of dopamine-producing cells that cause the event of Parkinson’s. However, an identical loss can also occur in other rarer neurological conditions. With no molecular test for the condition, a diagnosis is formed by a neurologist supported a mixture of symptoms like tremor, slowness, stiffness, and balance issues. However, many of the symptoms of Parkinson’s can overlap with other conditions, especially within the early stages when progression is gradual and symptoms are more subtle.
In a recent survey of quite 2,000 people with Parkinson’s administered by Parkinson’s UK, quite 1 / 4 (26 percent) reported they were misdiagnosed with a special condition before receiving the right Parkinson’s diagnosis.¹
Professor David Dexter, Associate Director of Research at Parkinson’s UK, said: “We are proud to possess part-funded this groundbreaking research which marks a big step towards developing a fast and accurate test which will not only revolutionize the way we diagnose Parkinson’s, but also allow us to watch how this debilitating condition progresses.
“Every hour, two more people within the UK are diagnosed with Parkinson’s, and a big portion of those people could are misdiagnosed with, and treated for, another condition before receiving their correct diagnosis. This has been compounded within the COVID-19 pandemic where people are left waiting and have faced months of hysteria to verify their diagnosis by a health care provider. However, with this innovative test, we could see people being diagnosed quickly and accurately enabling them to access vital treatment and support to manage their Parkinson’s symptoms sooner.”
56-year-old Daxa Kalayci lives in Leicester and was diagnosed with Parkinson’s in September 2019. She was misdiagnosed several times over four years before finally checking out she had the condition.
“I was misdiagnosed with anxiety, stress-related tremors, and told that my problems stemmed from browsing the menopause. I began a 4-month cruise across the world not knowing I had Parkinson’s. Just a fortnight into the trip, my symptoms worsened and my dream holiday became a nightmare. Without confirmation that it had been Parkinson’s, which I had suspected for an extended time, I used to be left with unpleasant side-effects caused by different medications prescribed to manage my symptoms.
“Despite my diagnosis eventually being confirmed by a DaTscan, a fast and straightforward diagnostic assay for Parkinson’s would have given me the prospect to start out my treatment earlier and luxuriate in life tons more. But instead, I lost numerous years of not having the ability to pursue a career as a paramedic or return to Nursing.
“This test might be a game-changer for people living with Parkinson’s and checking out answers like I used to be. I'm so proud of this news because it'll mean that within the future people won’t need to experience the anxiety of multiple appointments, long waiting times, and sleepless nights. the earlier this test is out there, the higher. Anything which will help people trying to find a diagnosis may be a bonus.”
