Infection With Ascaris Eggs Relieves Symptoms Of Ulcerative Colitis

Infection With Ascaris Eggs Relieves Symptoms Of Ulcerative Colitis.

The container of a cover who swallowed parasite eggs to treat his ulcerative colitis - and in reality got better - sheds light on how "worm therapy" might help heal the gut, a experimental study suggests. "Our findings in this case report suggest that infection with the eggs of the T trichiura roundworm can alleviate the symptoms of ulcerative colitis," said consider leader P'ng Loke, an aide professor in the department of medical parasitology at NYU Langone Medical Center found here. A magnanimous parasite, Trichuris trichiura infects the large intestine.

The findings could also lead to different ways to treat the debilitating disease, a form of inflammatory bowel disease (IBD) currently treated with drugs that don't always a post and can cause serious side effects, said Loke full report. The reading findings are published in the Dec 1, 2010 issue of Science Translational Medicine.

Loke and his yoke followed a 35-year-old man with severe colitis who tried worm (or "helminthic") psychoanalysis to avoid surgical removal of his entire colon. He researched the therapy, flew to a tamper with in Thailand who had agreed to give him the eggs, and swallowed 1500 of them.

The man contacted Loke after his self-treatment and "was essentially symptom-free". Intrigued, he and his colleagues pronounced to follow the man's condition.

The study analyzed slides and samples of the man's blood and colon series from 2003, before he swallowed the eggs, to 2009, a few years after ingestion. During this period, he was practically symptom-free for almost three years. When his colitis flared in 2008, he swallowed another 2000 eggs and got better again, said Loke.

Tissue charmed during working colitis showed a large number of CD4+ T-cells, which are immune cells that produce the inflammatory protein interleukin-17, the gang found. However, tissue taken after worm therapy, when his colitis was in remission, contained lots of T-cells that set up interleukin-22 (IL-22), a protein that promotes wound healing.

Further, after worm therapy, the man's colon produced significantly more mucus who distinguished that a lack of mucus in the colon is linked with harsh symptoms. "We think the worms increase or restore mucus manufacture in the colon. Basically, the gut is trying to expel the worms.

This increase in mucus may play a capacity in relieving the symptoms. This is not the usual clinical trial, but you take your opportunities for unique observation where you can," said Dr Gerald W Dryden Jr, leader of the clinical research dividing of gastroenterology, hepatology and nutrition at the University of Louisville, in Kentucky.

Before this study, IL-22 had not been associated with good effect in IBD, said Dryden. "While it doesn't determine cause-and-effect, the study does seem to march an important, previously unknown association between IL-22 and response to helminthic therapy".

Causing abdominal pain, diarrhea and other symptoms, colitis affects about 700000 Americans, according to the Crohn's and Colitis Foundation of America. Scientists don't recollect what causes the disease, but conjecture that immune-system dysfunction plays a role.

Colitis is unexceptional in developed countries such as America - where parasitic worm infections are rare - and in Asia, Africa and Latin America, where more the entire population is infected, the study noted. Clinical trials with the pig whipworm Trichuris suis have improved the symptoms of both ulcerative colitis and Crohn's disease, and crude studies suggest that various parasitic worms can block inflammation, the study noted.

The analyse also suggests new, worm-based treatments for both ulcerative colitis and IBD. Research might put one's finger on molecules derived from worms that suppress inflammation, or pathways activated by worms that can be targeted by more customary approaches.

Right now, however, worm therapy is still not well-understood and could potentially backfire, the study warned. "The uncontrollable is that these worms themselves can cause harm and damage the gut. The individual in this study is favoured to have responded so well, but for other people the worm infection may exacerbate bowel inflammation" more about the author. Studies that use the pig worm, which should put less risk to humans, are under way.
