Gut Microbiome, Crohn’s Disease and Effect of Diet

At this past year’s NASPGHAN conference, Bob Baldassano indicated that a low-residue diet probably does not makes sense for the majority of patients with Crohn’s disease because it would not promote a ‘healthy’ gut microbiome.  Another article (Walter SS, Quiros A, et al. SOJ Microbiol Infect Dis 2014; 2: 1-13) supporting this argument has been published. (Thanks to Ben Gold for giving me this reference.)

In this study, the authors examined the gut microbiome from two healthy volunteers and compared them to six patients with Crohn’s disease (CD) (ages 16-50).  The CD cohort were in clinical remission and were not receiving probiotics.  Subjects were randomized to either a low-residue diet (LRD) or a specific carbohydrate diet (SCD).

Besides having some cool figures to explain their results, the key points:

  • The complexity of the gut microbiome was lower in IBD patients compared to healthy controls
  • Bacteroides fragilis was increased in fecal samples of IBD positive patients
  • There was a temporal response of gut microbiome to SCD with increased microbial diversity while the LRD diet was associated with a reduced diversity of the microbiome in patients with CD

While the number of patients participating in this study are low, the affects of these diets can still be measured due to the trillions of microbes in the gut microbiome.

From NASPGHAN:  Introducing New Website for Teens with Inflammatory Bowel Diseases: JustLikeMeIBD.org  PRESS RELEASE

New York, NY- January 20, 2015 – The number of inflammatory bowel disease (IBD) patients in the U.S. has now increased to an estimated 1.6 million, with approximately 5 percent of that patient population under the age of 18. In response to the growing number of kids with IBD, the Crohn’s & Colitis Foundation of America (CCFA) along with the NASPGHAN Foundation for Children’s Digestive Health and Nutrition, has launched a new website called “Just Like Me” for teenagers with Crohn’s disease and ulcerative colitis.

The interactive site will feature stories and videos from teens with IBD as well as information on school, dating, stress, diet, and research.
