Researchers found that a fecal transplant which samples collected from a healthy donor which seems to send Crohn's symptoms into remission in treatment. They also showed that stem cells can have lasting benefits for a serious Crohn's complication called fistula. Crohn's a chronic inflammatory disease that causes abdominal cramps, diarrhea, constipation and rectal bleeding that arises when the immune system mistakenly attacks the lining of the digestive tract. There are many numbers of drugs to treat Crohn's including translational medicine called biologics that blocks certain immune-system proteins.
Instead of suppressing the immune system, the transplants alter the environment that the immune system is reacting against the microbiome, which refers to the trillions of bacteria that dwell in the gut. The idea is to change the bacterial composition of the gut, and hopefully quiet the inflammation that causes symptoms.
