This is amazing- new discoveries happening and getting closer 🧬 🦓 🧬
Clinically, HSD and hEDS are currently indistinguishable and managed similarly.
📢New Research Identifies Potential Biomarkers for Diagnosing Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD)!
🩸A recent study funded by The Ehlers-Danlos Society, and published in the American Journal of Medical Genetics, has identified potential blood-based biomarkers that could help diagnose hEDS and HSD.
❗This discovery is significant because diagnosing hEDS and HSD has been challenging due to the lack of established laboratory tests and molecular markers.
What was the study, and what did it find❓
🔬In this study, researchers examined blood samples from 466 adults, including 94 diagnosed with hEDS and 80 with HSD.
1. The study revealed the presence of a specific 52 kDa fragment of fibronectin in the blood of every individual with hEDS and HSD. This fragment was notably absent in healthy controls, individuals with other types of EDS, and those with various kinds of arthritis.
2. The consistent presence of the 52 kDa fibronectin fragment in individuals with hEDS and HSD suggests a possible common underlying pathophysiology, thus questioning the differentiation between these conditions.
3. Additionally, a fragment of collagen I was found in all individuals with hEDS and HSD, although this fragment was also present in other conditions.
What could this study mean❓
The identification of these fragments could lead to the development of the first blood test for hEDS and HSD, providing a more reliable diagnostic tool for healthcare providers, and reducing the time to diagnosis, which currently averages around 12 years.
What are the next steps❓
The study's findings are a significant step forward, but the authors emphasize that before this test is ready for diagnostic use, other investigators must confirm the results in additional cohorts of hEDS, HSD, and controls.
The Ehlers-Danlos Society is sponsoring further confirmatory work. Currently, no diagnostic lab offers this test, but if validated, it could become an important tool in diagnosis and treatment trials and provide new insights into the underlying causes of hEDS and HSD. Of course, we will keep you up to date with all developments!
