Actual date on which the first participant was enrolled.

This study focuses on understanding a condition called Gastric Antral Vascular Ectasia (GAVE), often referred to as "watermelon stomach," which can cause gastrointestinal bleeding. The researchers aim to find out how common certain abnormalities are in the tiny blood vessels near the nails, using a method called nail fold video capillaroscopy (NVC), in patients who have GAVE. This study is important because it may reveal patterns that can help doctors better understand and treat GAVE, potentially improving patient care. Participants in this study will undergo a nail fold video capillaroscopy, a non-invasive procedure that examines the small blood vessels at the base of the fingernails. They will also have an endoscopic examination of the stomach lining, called an EGD, to observe the GAVE. The study will compare findings from the NVC with how the patients present clinically, which means looking at their symptoms and other medical indicators. By doing this, the study aims to draw connections between these examinations and the patients' experiences.

75 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Supportive Care Study

These studies explore ways to improve comfort and daily life for people living with a condition. They may focus on easing symptoms, reducing treatment side effects, or supporting overall well-being.

Patients with GAVE with connective tissue disease will be compared to patients with GAVE without a connective tissue disease. Exclusion Criteria: * Age less than 18 years of age, pregnant individuals, dialysis dependent, type 2 diabetes, recent hand trauma or manicure (\<2 weeks), routine use of vibratory tools, history of acrocyanosis or erythromelalgia, previous diagnosis of a bleeding disorder, diagnosis of psoriasis, diagnosis of anti-phospholipid syndrome, exposure to toluene or benzoyl, diagnosis of psoriasis, diagnosis of COPD.

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Will include patients between 18 and 95 years old seen at Mayo Clinic in Florida who were diagnosed with GAVE (Gastric antral vascular ectasia) based on the EGD findings. Will include patients with gave and connective tissue disease. Patient can be identified using slicer dicer or advanced text explorer and will be invited to have a nail fold video capillaroscopy.

Group II

Will include patients between 18 and 95 seen at Mayo Clinic in Florida who were diagnosed with GAVE based on the EGD findings. Will include patients with GAVE without connective tissue disease Patient can be identified using slicer dicer or advanced text explorer and will be invited to have a nail fold video capillaroscopy.
