Joint Hypermobility, Autonomic Dysfunction, Gastrointestinal Dysfunction and Autoimmune markers (JAG-A): Clinical Associations and Response to Intravenous Immunoglobulin Therapy.

Autoimmune markers and autonomic dysfunction are common in patients with unexplained gastrointestinal symptoms, especially in those with JH/HSD. Many patients seem to respond to IVIG treatment but this needs to be confirmed by controlled trials. These results highlight the need for vigilance for autoimmune and autonomic factors and JH/HSD in patients with neurogastroenterological disorders. Clinicaltrials.gov, NCT04859829.
