People with hEDS or HSD experience a wide range of symptoms and co-morbidities that go beyond their affected joints (e.g., dysautonomia, mast cell activation syndrome, neuropathic pain, digesGve troubles). These symptoms vary greatly between individuals in terms of their development, severity, and response to treatment, suggesting the existence of different sub-types. As highlighted in other diseases, it is difficult to find one single test or “biomarker” that applies to everyone with the condiGon. Instead, there could be subtypes, which could have their own specific biomarker.
We propose a detailed and thorough examination of a large group of people with hEDS/HSD, focusing on some of the main affected systems (neurological, digestive, immune, cardiac, cutaneous, respiratory). This will help us identify different subgroups of patients, and potentially find biomarkers specific to these subgroups. For this, we will analyze biological samples (blood, saliva and stool) in collaboration with fundamental research laboratories to identify potential biomarkers (e.g. related to the gut-microbiota as well as the neurological and immune systems.)
