Autoimmunity Clinical Trial
Official title:
Autoimmune Gastrointestinal Dysmotility: Symptoms, Pathogenesis and Treatment
Autoimmune gastrointestinal dysmotility syndromes are poorly understood, and often difficult to treat because the underlying pathogenesis is unclear. Refractory symptoms result in an impaired quality of life. The presence of positive serum autoantibodies to peripheral nervous system gangliosides and glycoproteins is suggestive of a possible mechanism. Immunomodulator treatments have shown benefit in case reports and case series but standardized data for treatment response is lacking. Therefore, our primary aims are to further characterize this syndrome in terms of symptoms, laboratory testing, pathology, and assess treatment response of immunomodulator therapy. Our research plan involves identifying this subset of patients with autoimmune gastrointestinal dysmotility and dysautonomia, and studying them as they are managed by their gastroenterologists.The study team will administer symptom-based questionnaires in a systematic manner to assess the clinical trajectory of this population and treatment response. The investigators will also analyze laboratory values (antibody titers, tilt testing, inflammatory markers) and study pathology specimens (enteric and skin biopsies) obtained from this cohort to gain a deeper understanding of the pathogenesis of their disease.
