    Researchers Hunt Causes of Non-responsive Celiac Disease

    Reviewed and edited by a celiac disease expert.

    Celiac.com 03/18/2009 - A recent study used lactulose hydrogen-breath assays to show that small intestine bacterial overgrowth (SIBO) is likely a routine cause of non-responsive celiac disease.

    A team of researchers from the Mayo Clinic College of Medicine recently set out to assess the rates and significance of SIBO in celiac disease based on the results of quantitative culture of intestinal aspirate.

    Celiac.com Sponsor (A12):
    The team was made up of Alberto Rubio-Tapia, M.D., Susan H. Barton, M.D., Joseph A. Murray, M.D., of the Mayo’s Division of Gastroenterology and Hepatology, and Jon E. Rosenblatt, M.D., of the Mayo’s department of Laboratory Medicine and Pathology. Their efforts were supported by the American College of Gastroenterology (ACG) International Training Grant 2006 (ART) and the NIH grants DK-57892 and DK-070031 (JAM).

    Currently, the rate of SIBO in celiac disease diagnosed by quantitative culture of intestinal aspirate is not known. The team set out to assess the rate and determine the significance of SIBO in celiac disease based on the results of quantitative culture of intestinal aspirate.

    The team set out to examine the causes of non-responsive celiac disease by looking at people with celiac disease in whom culture of intestinal aspirate was assessed for the presence of both aerobic and anaerobic bacteria. They defined bacterial overgrowth as culture >105 colony forming units/mL.

    In all, they evaluated 149 people with biopsy-confirmed celiac disease. They took intestinal aspirate samples from 79 (53%) patients with non-responsive celiac disease, 47 (32%) as initial work-up for mal-absorption, and in 23 (15%) with asymptomatic treated celiac disease.

    The team diagnosed 14 cases of SIBO (9.3%), nine cases of non-responsive celiac disease (11%), five cases at initial work-up for mal-absorption (11%), and 0 cases in asymptomatic treated celiac disease. Patients with a positive culture showed signs of worse mal-absorption. 67% of patients with both non-responsive celiac disease and bacterial overgrowth showed a coexistent disorder.

    The results showed that nearly 1 in 10 celiac patients had SIBO as diagnosed by quantitative culture of intestinal aspirate (9.3%). This figure included both patients with symptomatic treated or untreated celiac disease. This shows that SIBO may exist along with other maladies associated with non-responsive celiac disease.

    Would like more information. What other conditions were present among comorbid and asymptomatic patients, particularly if any were diagnosed with Chron's disease.

    Does SIBO cause bad breath and 'coverage of stuff' on your tongue that I have to use a tongue scarper on daily.

    Am J Gastroenterol. 2002 Aug;97(8):2016-21 Celiac.com 01/29/2004 - According to researchers at the Mayo Clinic in Rochester Minnesota, the main causes of non-responsive celiac disease are: "1) gluten contamination is the leading reason for non-responsive celiac disease; 2) of non-responsive celiac disease cases, 18% are due to Refractory Sprue; and 3) alternative diseases or those coexistent with celiac disease and gluten contamination should be ruled out before a diagnosis of Refractory Sprue is made." The researchers define Refractory Sprue as "failure of a strict gluten-free diet to restore normal intestinal architecture and function in patients who have celiac-like enteropathy," and conducted a study to determine possible causes, including how many people actually have Refractory...

      Ground meat absolutely full of gluten?

      Ground meats can contain flavorings and fillers. You must look for the gluten-free symbol on the packaging. I use Jennie-O brands which are marked gluten-free.

      Gluten Free ADHD medications

      I take Clonidine for blood pressure control. It is the only one that did not debiltate me. It also helps with my ADD. Doctors always turned me down when I requested Ritalin (I am an adult) so it turned out for the best that I reacted badly to all the different BP meds they tried. Originally Clonidine was developed for ADHD adolescents that could not...
