MRI to Assess Fibrosis in Eosinophilic Esophagitis Patients

Study Purpose

Can an MRI detect and monitor the inflammatory and fibrotic possess in patients with Eosinophilic Esophagitis

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion criteria:

  • - Adults ages 18-70 years of age - Diagnosis of EoE, i.e. symptoms of esophageal dysfunction with histologic finding of 15 or more eosinophils per high power field on esophageal biopsy despite 8 weeks of high dose proton pump inhibitor therapy.

Exclusion criteria:

- Clinical evidence of infectious process potentially contributing to dysphagia (e.g. candidiasis, CMV, herpes) - Other cause of dysphagia identified at endoscopy or esophagram (e.g. reflux esophagitis, stricture, web, ring, achalasia, esophageal neoplasm) - Esophageal minimal diameter < 13 mm on structured barium esophagram - Inability to read due to: Blindness, cognitive dysfunction, or English language illiteracy - Pregnant women - Presence of body metallic fragments or devices that prohibit use of MRI - History of renal disease - eGRF <30

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03446118
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

MRI will be performed on a 1.5T magnet. Patients will be scanned in an oblique prone position similar to how esophageal distention is assessed at barium fluoroscopy. The following sequences and rationale will be used for the examination: A sagittal 50mm thick multiphase FIESTA and multiphase SSFSE will be performed while the patient drinks water. The temporal resolution of the images will be approximately 1 image every 1.5-2 seconds. The images will be used to assess the lumen caliber and the wall thickness during maximal distension as pseudothickening can occur with decreased luminal distension. Sagittal SSFSE with fat suppression, sagittal FRFSE T2-weighted images with fat suppression, axial DWI and sagittal DWI will be performed to asses for edema and inflammation within the esophageal wall. axial FS SSFSE or FIESTA will be performed and targeted to the region of stricturing. Dynamic sagittal imaging will be performed following IV contrast to assess for mural hyperenhancement which can be seen mural inflammation and delayed enhancement which can be seen in fibrosis. Sequential acquisitions will be performed beginning at 40 seconds following IV contrast injection. Delayed acquisitions will be performed at 5 min and 7 min. Patients will be asked to perform swallowing during the image acquisition to reduce the potential for pseudoenhancement secondary to under distension.
