Porcine Whipworm Ova Safe for Treatment of IBD



New Delhi:

Orally ingested ova of Trichuris suis, the porcine whipworm, has been found to be active in an open-label study of Crohn’s disease, and in a small scale, placebo-controlled trial in patients with ulcerative colitis said Padma Shri and Dr B C Roy National Awardee Dr KK Aggarwal, President Heart Care Foundation of India.

Inflammatory bowel diseases are diseases of the affluent society. Many trials have shown that infection with parasitic worms is protective. Intestinal helminthes induce Th2 cytokine release and specifically down regulate Th1 responsiveness

Administering eggs from the porcine whipworm Trichuris suis to patients with Crohn’s disease and ulcerative colitis is a safe and possibly effective treatment for inflammatory bowel disease according to a report published in the American Journal of Gastroenterology. In the open-label trial, 29 patients with refractory disease, and a Crohn’s disease activity index (CDAI) of 220 to 450, ingested 2,500 T. suis ova in a beverage every three weeks for 24 weeks. By week 12, 22 patients (75.9%) experienced a decrease in CDAI of more than 100 points, or had a CDAI of less than 150. Another 18 patients (62.1%) were in remission. (Four patients withdrew early because of disease activity or pregnancy.) They observed no adverse effects or complications. In the treatment a single dose of 2500 live Trichuris suis eggs are given
