Brief Summary

Patients with a bowel condition called ulcerative colitis have bowel surgery in which a portion of their bowel is removed and the reconnected at the small bowel to the anus. Sometimes, after the surgery, this connection part, the pouch, would be inflamed in a condition called Acute Pouchitis. Physicians usually treat them by prescribing antibiotics; however, some patients do not respond and need additional surgery. In this study, we will test an alternative treatment for this complication by performing manuka honey enemas twice a day for 30 days. This is a pilot study and ten patients will undergo enema treatment.

Detailed Description

Pouchitis is the most common long-term complication of ileal pouch-anal anastomosis (IPAA) in ulcerative colitis (UC). Pouchitis is defined as a clinical syndrome of watery, frequent, at times bloody stool accompanied by urgency, incontinence, abdominal cramps, malaise, and fever. The PDAI (Pouchitis Disease Activity Index) provides a standardized definition of pouchitis based on clinical, endoscopic, and histological markers. Pouchitis is defined as a score ≥ 7 and remission as a score < 7. Recently, the modified Pouchitis Disease Activity Index has been used to omit biopsy and histology from the standard PDAI. Omission of endoscopic biopsy and histology from the PDAI simplifies pouchitis diagnostic criteria, reduces the cost of diagnosis, and avoids delay associated with determining histology score, while providing equivalent sensitivity and specificity. Patients with acute pouchitis are managed routinely by antibiotics such as Ciprofloxacin and Metronidazole. This treatment has some side effects, is expensive, and fails to respond in some patients. Some patients who are unresponsive to antibiotic therapy will need to have a pouchectomy and ileostomy done.

On the other hand, multiple studies have shown that honey, especially manuka honey has anti-inflammatory, anti-bacterial, wound healing, and anti-ulcerous effects. Phenolic compounds in honey, such as flavonoids, have been reported to exhibit a wide range of biological activities, including antibacterial, antiviral, anti-inflammatory, antioxidant, antitumor, anti-allergic, and vasodilatory actions. This honey can clear infection, remove malodour, reduce inflammation and pain, cause edema and exudation to subside, and increase the rate of healing by stimulation of angiogenesis, granulation and epithelialization.

Due to problems associated with antibiotic therapy, such as side effects, cost and failure of some patients to respond, we are looking to find an alternative method for treating acute pouchitis. This study is designed to determine the effect of manuka honey on symptoms, signs and pathology of acute pouchitis patients. We will select patients with any of the signs and symptoms of pouchitis, such as abdominal pain, fever, frequency or urgency of defecation. Proctoscopy will be done before and after honey enema and the modified PDAI scores will be determined. The manuka honey enema will be administered twice a day, for one month. Then, the modified PDAI scores before and after completion of honey enema treatment of these patients, will be compared.

We know that bacterial overgrowth, ischemia, faecal stasis, recurrence of ulcerative colitis in the pouch, or possibly a novel third form of inflammatory bowel disease, are possible etiologies of pouchitis. We also know that manuka honey has anti-inflammatory and anti-bacterial properties. Some studies demonstrate that honey is effective in the treatment of induced colitis in animal models. However, there is no current literature on the effect of honey on colitis or pouchitis in humans. Based on the aforementioned properties of honey, and considering the probable etiologies of pouchitis, we expect that these patients will respond to this method of treatment.

Some research has been done on the effect of honey in the treatment of colitis in animal models, but there have been no clinical studies that have assessed this treatment in pouchitis, or even colitis, in humans. Considering the etiologies of pouchitis, such as inflammation and bacterial overgrowth, and considering the main effects of honey, such as anti-bacterial and anti-inflammatory efficacy, honey enema may be useful in the treatment of pouchitis. Our study is trying to determine the effect of manuka honey enema in the treatment of acute pouchitis. We will try to determine whether the honey enema helps to decrease inflammation and infection in the pouch, and thereby provide us with a safe alternative method for the treatment of pouchitis.

In this pilot study, we will select patients who have any of the signs and symptoms of acute pouchitis, such as abdominal pain, fever, frequency, or urgency of defecation. Proctoscopy will be performed on these patients. Ten patients with modified PDAI score ≥ 7 will receive honey enemas twice a day for one month. We chose a twice daily enema regimen, because patients with inflammatory bowel disease usually receive their enemas twice a day. We expect one month to be enough time, because the duration of antibiotic therapy for patients with acute pouchitis is about one month. Then, the PDAI score of these patients, before and after honey enema will be compared.
