Probiotics are crucial for maintaining my remission. Here is some research indicating that my experience may not be entirely placebo:
One of the most studied probiotics is lactobacillus GG. Children (median age, 14.5 years) with mildly to moderately active Crohn's disease despite therapy with prednisone and immunomodulatory drugs (such as 6-mercaptopurine, azathioprine, or methotrexate) were given Lactobacillus GG twice a day for six months. The median pediatric Crohn's disease activity index score at four weeks was 73% lower (better) than at baseline, and three patients had a score of less than 10, indicating inactive disease. In some patients it was possible to taper the dose of prednisone by an average of 50% after 12 weeks of Lactobacillus GG treatment. Intestinal permeability, measured by a double sugar permeability test, improved in an almost parallel fashion. The researchers concluded that Lactobacillus GG may improve gut barrier function and clinical status in children with mildly to moderately active Crohn's disease.
A study published in the February 2005 issue of the journal Gut found that administration of a probiotic and a prebiotic to patients with ulcerative colitis improved inflammatory symptoms and helped regenerate epithelial tissue. Researchers from Ninewells Hospital Medical School in Dundee, Scotland gave the freeze-dried probiotic Bifidobacterium longum combined with a prebiotic consisting of a mixture of fructo-oligosaccharides and inulin to 8 patients with ulcerative colitis, while 8 patients with the disease received a placebo. Sigmoidoscopic examinations were conducted and rectal biopsies were obtained before and after the one month treatment period.
It was found that consuming the probiotic/prebiotic combination was associated with a reduction in mucosal inflammation ascertained via sigmoidoscopy, while the placebo group worsened. Inflammatory cytokines tumor necrosis factor alpha and interleukin-1 alpha were significantly reduced in the treatment group. The biopsies also revealed regeneration of epithelial tissue in those who received the probiotic.
E.coli (Nissle strain 1917) was as effective as mesalazine in preventing relapse of ulcerative colitis for 116 patients and again in 120 patients via two double- blind studies.
Thirty-two patients with Crohn's disease in clinical remission were randomly assigned to receive one of the following for 6 months: 1) mesalamine (1 g 3 times per day) or 2) mesalamine (1 g 2 times per day) plus Saccharomyces boulardii (1 g in the morning). Clinical relapse, defined as a Crohn's disease activity index greater than 150 with an increase of 100 points over the baseline value for more than 2 weeks, occurred in 6 of 16 patients (37.5%) receiving mesalamine alone and in 1 of 16 patients (6.25%) receiving combination therapy (p=0.04).
