A brand new machine for diagnosing osteoporosis invented by the Hospitals of the College of Geneva (HUG) and the College of Geneva (UNIGE) has been authorised for advertising and marketing within the European Financial Space and Switzerland. It was launched this summer season below license from Northern Irish firm ProAxsis. The machine relies on a brand new strategy to evaluate bone high quality by blood sampling. This check is extra particular than present applied sciences and can drastically enhance prognosis and drive the event of recent remedies for osteoporosis.

Osteoporosis is a significant public well being drawback. The principle trigger is osteoporosis, which impacts 30% of the Swiss inhabitants. Sort 2 diabetes, which impacts 10% of the inhabitants, is a threat issue as a result of it will increase the danger of fracture virtually twice.

Because the inhabitants ages, osteoporosis and osteoporosis fractures are anticipated to extend by 23% in EU nations, from 2.7 million in 2017 to three.3 million in 2030. In Switzerland, the present annual variety of 82,000 osteoporotic fractures is predicted to rise to Roughly 105,000 in 25 years.

Osteoporosis have to be recognized earlier than a fracture happens, as a result of relying on the age of the individual and the affected bone, a fracture can result in extreme power ache and even enhance the danger of dying.

The premise of this invention lies within the properties of the periosteum, a membrane that covers bones and performs a vital position of their progress and restore. It secretes a key protein that controls bone diameter and, due to this fact, its energy: periostin. Throughout bone resorption, the enzyme cathepsin Ok breaks it down. The a part of the digested periyostin, known as k-POSTN, can be discovered within the blood, thus reflecting osteoporosis. The importance of this piece lies within the peculiarity of its bones, in contrast to intact periyostin, which has been identified to scientists for a very long time, however may also enhance cardiovascular illnesses and cancers. After the blood pattern is taken, the quantity of k-POSTN is measured in a laboratory utilizing the ELISA assay, a broadly used methodology for measuring molecules in a organic pattern.

The brand new machine has the potential to assist healthcare professionals determine and monitor folks at excessive threat of osteoporotic fractures in addition to these with weak bone illnesses, together with sort 2 diabetes. As well as, it permits for therapeutic intervention at an early stage, earlier than a fracture happens, a reality that ought to undoubtedly scale back the burden of orthopedic illness on well being techniques and considerably enhance sufferers’ high quality of life.

This machine is meant to enhance bone densitometry, the imaging expertise presently used to evaluate osteoporosis. “This can be a course of that may sadly be biased within the case of sort 2 diabetes. The rise in weight and fats mass typical of diabetes blurs the measurement of bone mineral density, which can seem regular regardless of the presence of fragile bone tissue. The brand new machine overcomes these limitations.” , says Serge Ferrari, chief of HUG’s Orthopedic Service, Emeritus Professor within the Division of Drugs at UNIGE Faculty of Drugs and co-inventor.

k-POSTN improves prediction of osteoporosis by growing the accuracy and specificity of methods presently used to determine folks in danger for bone fractures. “Our prognosis will allow researchers and pharmaceutical corporations concerned in creating new remedies for osteoporosis to acquire correct, particular, and quantitative measures of the impact of their experimental merchandise,” says Serge Ferrari.

Distinctive improvement course of

This discovery is the results of the work of Professor Serge Ferrari and Nicolas Bonnet, a non-public doctor within the Division of Drugs at UNIGE Medical Faculty.

They found for the primary time this new course of primarily based on the direct measurement of a product of the biochemical technique of pure bone degradation. They then started creating the ELISA check in 2014. HUG and UNIGE filed an preliminary patent in 2016, after which the check capabilities and high quality took care of ProAxsis Ltd, primarily based in Northern Eire, for a license in 2021. The check obtained the CE mark In June 2022 for advertising and marketing in Europe.

Serge Ferrari concludes, “It’s not typically {that a} product developed in a college hospital is marketed. And even much less so in such a short while. We owe it to the wonderful cooperation with our companions.”
