Viral esophagitis

This study tests whether giving patients donor-derived immune cells (VSTs) on a regular schedule can prevent dangerous viral infections after a stem cell transplant. 180 participants will be randomly assigned to receive VSTs either on a fixed schedule or only when a virus is dete…

This study tests whether a Botox injection into the stomach valve works as well as a surgical cut to prevent food from emptying too slowly after esophagus removal. About 170 adults having elective esophagectomy will be randomly assigned to one of the two procedures. Researchers w…

This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boos…

This study tests a magnetically controlled capsule endoscope—a tiny camera you swallow—to painlessly screen the esophagus and stomach. Researchers will compare different swallowing protocols to see which gives the best view of the Z-line and other areas. 300 patients already sche…

This study aims to collect samples and medical information from people of all ages who have or have been exposed to viral infections, including COVID-19 and herpes. Researchers want to understand how viruses affect healthy individuals versus those with weakened immune systems. Pa…

This trial asks whether single-use gastroscopes work as well as standard reusable ones for elective and subacute upper GI procedures. About 300 adults will be examined with either a disposable or a reusable scope, and endoscopists will rate performance on a questionnaire. The stu…

This study compares two techniques—esophageal manometry and EndoFLIP balloon measurements—to evaluate how well they assess swallowing difficulties (dysphagia). Researchers will enroll up to 1,000 patients with known esophageal conditions to see how these measurements relate to sy…

This study is creating a large database of information from 10,000 people with esophagus problems like GERD, achalasia, and other motility disorders. Researchers will collect data from standard tests to better understand these conditions. The goal is to improve diagnosis and trea…
