Clinical Trial Summary

Obsessive-compulsive disorder (OCD) is a psychiatric condition marked by recurrent intrusive thoughts (obsessions) and ritualistic behaviors aimed at reducing distress (compulsions). While there exist a number of medications to treat this illness, half of those who need them either do not respond or can not tolerate current medications because of side effects. Therefore, there is an urgent need to develop new ways to treat this illness. One of the areas being explored as a potential option is based on what is now known as a strong link between the bacteria that live in our gut and the brain. Research has shown that a fecal transplant of the gut bacteria from healthy donors is able to improve health outcomes for people with depression and the investigators now want to expand this into OCD, given a known link between this condition and bacterial infection. To do this the investigators will use both the standard methods of bacterial identification via stool analysis, which looks at large bowel changes, and compare it to the Small Intestine Microbiome Aspiration (SIMBA) system, a small capsule that when swallowed allows a fluid sample to be collected from the participants' small intestine. This work will help the investigators assess the benefits of fecal transplant in OCD, and more importantly, identify how transplant changes the system, utilizing a novel technology to move the field forward.
