Observing autonomic neuropathies and Ehlers Danlos syndromes over time

Autonomic Neuropathy and Its Pathophysiology in Autoimmune Autonomic Neuropathies, Postural Orthostatic Tachycardia Syndrome and Ehlers Danlos Syndromes: Peripheral Autonomic Small Fiber Neuropathy or Central Autonomic Failure? Validation of the Malmö POTS Score and a Better Diagnosis of POTS in Patientes With Autnomic Failure (VaGeMAPS-3-step-Diag)

Observational RWTH Aachen University · NCT04310644

What this trial studies

This study examines patients with various autonomic neuropathies and Ehlers Danlos syndromes, comparing them to healthy controls at three different time points: baseline, after 3 months, and after 1.5 years. The goal is to gain insights into the progression of these conditions and their underlying mechanisms, particularly focusing on small fiber neuropathy. Participants will undergo a series of assessments, including laboratory tests, questionnaires, and specialized tests to evaluate their health status and nerve function. The study also aims to validate a German version of the Malmö POTS Score and create a straightforward diagnostic scheme for outpatient care.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18-80 with autonomic neuropathy, postural orthostatic tachycardia syndrome, hypermobile or classical Ehlers Danlos syndromes, chronic fatigue syndrome, mast cell activation syndrome, or PostCOVID syndrome.

Not a fit: Patients with pregnancy, pacemakers, deep brain stimulation, sensory or motor polyneuropathy, or neurodegenerative diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding and management of autonomic neuropathies and Ehlers Danlos syndromes, leading to better patient outcomes.

How similar studies have performed: While this study builds on existing knowledge, the specific combination of conditions and the proposed methodology may offer novel insights into these syndromes.
