The purpose of this research is to determine whether a procedure called capillaroscopy can help distinguish patients who are diagnosed with GAVE (gastric antral vascular ectasia) with an autoimmune disease versus idiopathic/other conditions based on EGD findings.
The primary aim of this study is to define the prevalence and findings (as per quantification) of nail fold video capillaroscopy abnormalities in patients with GAVE. The secondary aim is to compare the findings of NVC and clinical presentation in patients with GAVE.
Inclusion Criteria: * Patients 18 years and older with gave diagnosis as pair EGD performed in Gastroenterology as standard of care. Patients with GAVE with connective tissue disease will be compared to patients with GAVE without a connective tissue disease.
