    Can a Gluten-free Diet Reduce Symptoms of Irritable Bowel Syndrome?


    Jefferson Adams

    Celiac.com 06/14/2013 - A team of researchers recently conducted a controlled trial of gluten-free diet in patients with irritable bowel syndrome-diarrhea to gauge the effects on bowel frequency and intestinal function. Their goal was to determine whether a gluten-free diet might benefit patients with diarrhea-predominant irritable bowel syndrome (IBS-D).

Zinsmeister. They are variously affiliated with the Clinical Enteric Neuroscience Translational and Epidemiological Research at the Mayo Clinic in Rochester, Minnesota, and the Division of Gastroenterology and Hepatology at the Mayo Clinic in Jacksonville, Florida.

    The team designed a randomized controlled 4-week trial comparing the effects of a gluten-containing diet against gluten-free diet in 45 patients with IBS-D.

    They conducted genotype analysis for HLA-DQ2 and HLA-DQ8, and randomly placed twenty-two patients on the gluten-containing diet (11 HLA-DQ2/8 negative and 11 HLA-DQ2/8 positive) and 23 patients on the gluten-free diet (12 HLA-DQ2/8 negative and 11 HLA-DQ2/8 positive).

    They measured daily bowel function, small-bowel and colonic transit. They used lactulose and mannitol excretion to measure mucosal permeability, and peripheral blood mononuclear cells after exposure to gluten and rice to gauge cytokine production.

    The team collected rectosigmoid biopsy specimens from 28 patients, analyzed levels of messenger RNAs encoding tight junction proteins, and performed H&E staining and immunohistochemical analyses.

    They analyzed covariance models to compare data from the gluten-containing and gluten-free diet groups.

    They found that subjects on the gluten-containing diet had more bowel movements per day (P = .04); the gluten-containing diet had a greater effect on bowel movements per day of HLA-DQ2/8-positive than HLA-DQ2/8-negative patients (P = .019).

    They also found that the gluten-containing diet was associated with higher SB permeability, based on 0-2 h levels of mannitol and the ratio of lactulose to mannitol. They found that SB permeability to be greater in HLA-DQ2/8-positive than HLA-DQ2/8-negative patients (P = .018), and saw no significant differences in colonic permeability.

    Patients on the gluten-containing diet had a small decrease in expression of zonula occludens 1 in SB mucosa and significant decreases in expression of zonula occludens 1, claudin-1, and occludin in rectosigmoid mucosa.

    The effects of the gluten-containing diet on expression were substantially greater in HLA-DQ2/8-positive patients. Neither diet had any significant effects on transit or histology.

    Peripheral blood mononuclear cells produced higher levels of interleukin-10, granulocyte colony-stimulating factor, and transforming growth factor-α in response to gluten than rice, regardless of HLA genotype.

    The team's findings show that gluten alters bowel barrier functions in patients with IBS-D, especially in HLA-DQ2/8-positive patients, and that these aspects of IBS can be reversed with a gluten-free diet.

    Could you please make a final point, in layman's term so a person can actually understand and determine if the gluten-free diet was helpful or not? While your information is detailed, it is not clear if it was indeed recommended for a person with IBS or not. Thank You!

    Just fyi, dappy, many people who've had diarrhea, short or long-term from any cause, need probiotics to help their digestive system get back to normal. Diarrhea sends the good bacteria out of your system - think of flushing the pipes. All of the good goes out with the rest. We have to re-establish good bacteria in the intestine.

     

    I recently read of a study that pointed to having a large variety of bacteria seemed to be protective against developing celiac disease. The site doesn't allow links to be posted, but if you google "pubmed+Lower economic status and inferior hygienic environment may protect against celiac disease" you can read the study results.

    I have tried the probiotic and now gluten-free. I'm finding that my IBS reacts now if I eat something with gluten. The flareups are far worse with gluten as opposed to the gluten-free options.

     

    My GP and Internist are hesitant to pursue celiac disease as my bloodwork shows no reactivity due to the sheer lack of gluten in my diet now. I am not prepared to start eating gluten just to re-confirm what I already have figured out.

    I agree, what the heck did this article say??? I have a serious case of IBS and I am wondering if I should go on a gluten-free diet.

    Lancet Nov 2001 Volume 358, Number 9292 1504-08 03
    Celiac.com 11/14/2001 - A recent study published in The Lancet by Dr. David S Sanders et al. of the Gastroenterology and Liver Unit, Royal Hallamshire Hospital, Sheffield, UK, explored the number of people who were diagnosed with irritable bowel syndrome but actually had celiac disease.
    The case-control study was done at a university hospital in which 300 consecutive new irritable bowel syndrome patients who met the Rome II criteria for their diagnosis were compared against 300 healthy age and sex-matched controls. Both groups were investigated for celiac disease by analysis of their serum IgA antigliadin, IgG antigliadin, and endomysial antibodies (EMA). Patients and controls with positive antibody results were offered duodenal biopsy to confirm the possibility of celiac disease.
    An amazing 66 patients with irritable bowel syndrome tested positive for the antibodies, and 14 of them or 4.6% had active celiac disease as compared with 2 or 0.66% of the non-IBS matched controls. In other words there is a sevenfold increase over the normal population in the number of people with IBS who have celiac disease. All of the patients with celiac disease in the IBS group were therefore misdiagnosed. The study did not indicate how many of the other 52 patients who had positive antibody results would eventually develop celiac disease, but this would be an interesting follow-up study. Celiac.com believes that the 4.6% with celiac disease will grow higher over time.
    Conclusion: All patients with irritable bowel syndrome should be screened celiac disease.

    Aliment Pharmacol Ther 19(11):1199-1210, 2004.
    Celiac.com 06/08/2004 - Researchers at the University of California, San Francisco have determined that everyone with Irritable Bowel Syndrome (IBS) should also be screened for celiac disease. The researchers used decision analysis to estimate the number of celiac disease cases detected, quality-adjusted life-years gained, and costs resulting from screening suspected IBS patients for tissue transglutaminase antibody and antibody panel. Positive tests were followed up with an endoscopic biopsy. A gluten-free diet was initiated to improve the quality of life in those with celiac disease.
    The results of this study indicate that 3% of the 1,000 patients with suspected IBS have celiac disease. Based on these results the researchers analyzed the costs of several celiac disease screening methods used a decision analysis formula to determine whether or not the screening is cost effective. The researchers conclude that celiac disease screening in patients with suspected irritable bowel syndrome is likely to be cost-effective even at a relatively low celiac disease prevalence.
    Perhaps the researchers should have taken their analysis one step further and concluded that it would make good economic sense to screen the entire population of the USA (as well as that of other countries) for celiac disease, rather than just those with IBS, given the fact that it affects approximately 1% of the population--which is the only conclusion that I could reach after my review of their good work. -Scott Adams

    Celiac.com 02/25/2013 - Patients with celiac disease often report symptoms compatible with irritable bowel syndrome (IBS). However, there haven't been any systematic studies regarding how adherence to a gluten-free diet might affect rates of irritable bowel syndrome-type symptoms in patients with celiac disease.
    To better answer that question, a research team conducted a meta-analysis of celiac disease patients to determine rates of irritable bowel syndrome-type symptoms, and how those symptoms relate to a gluten-free diet.
    The research team included A. Sainsbury, D.S. Sanders, and A.C. Ford, of the Leeds Gastroenterology Institute at St James's University Hospital in Leeds, United Kingdom.
    For their analysis, the team searched MEDLINE, EMBASE, and EMBASE Classic to identify cross-sectional surveys or case-control studies reporting prevalence of IBS-type symptoms in adult patients (≥16 years old) with established celiac disease.
    The team used case or control status and adherence to a gluten-free diet to determine the number of individuals with IBS symptoms.
    The team analyzed data from 7 studies with 3383 participants.
    They then calculated pooled prevalence and odds ratios (ORs), with 95% confidence intervals (CIs).
    They found that pooled prevalence of IBS-type symptoms in all patients with celiac disease was 38.0% (95% CI, 27.0%-50.0%).
    People with celiac disease had higher pooled odds ratios for IBS-type symptoms than did control subjects (5.60; 95% CI, 3.23-9.70).
    In patients who did not follow a strict gluten-free diet, the pooled odds ratios for IBS-type symptoms, compared with those who were strictly adherent, was 2.69 (95% CI, 0.75-9.56).
    Patients who did not adhere to the gluten-free diet had higher odds ratios for IBS-type symptoms compared with controls (12.42; 95% CI, 6.84-11.75).
    Such patients also had higher odds ratios compared with that observed for celiac disease patients who followed a strict gluten-free diet or controls (4.28; 95% CI, 1.56-11.75).
    The results show that patients with celiac disease suffer IBS-type symptoms more frequently than control subjects, and that following a strict gluten-free diet might help to reduce those symptoms.

    Celiac.com 06/04/2015 - Some researchers feel that people who self report non-celiac gluten sensitivity (SR-NCGS) and also follow a gluten-free diet might actually fall within the spectrum of irritable bowel (IBS). Interestingly, recent reports suggest that large numbers of people with inflammatory bowel disease (IBD) also follow a gluten-free diet.
    A research team recently assessed the relationship between IBD and self-reported non-celiac gluten sensitivity (SR-NCGS). The team included I.Aziz, F. Branchi, K. Pearson, J. Priest, and D.S. Sanders. They are variously affiliated with the Department of Gastroenterology, Royal Hallamshire Hospital, Sheffield Teaching Hospitals, Sheffield, United Kingdom; and the Gastroenterology and Endoscopy Unit in the Department of Pathophysiology and Transplantation at the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico, Department of Pathophysiology and Transplant, Università degli Studi di Milano in Milan, Italy.
    To screen for SR-NCGS and the use of a GFD, they used a cross-sectional questionnaire in 4 groups: ulcerative colitis (n = 75), Crohn's disease (n = 70), IBS (n = 59), and dyspeptic controls (n = 109). They also looked at diagnostic outcomes for IBD in 200 patients presenting with SR-NCGS.
    A total of 25 out of 59 patients with IBS (42.4%), and 40 out of 145 patients (27.6%) with IBD reported SR-NCGS. That number was just 19 of 109 for dyspeptic control subjects (17.4%). As far a gluten-free diet, currently, 11.9% of patients with IBS, and 6.2% of those with IBD are following a gluten-free diet, as compared with just 0.9% for dyspeptic controls; P = 0.02.
    For the purposes of of this study, the team made no differences between ulcerative colitis and Crohn's disease. However, 40.9% of Crohn's disease patients with SR-NCGS suffered from stricturing disease, compared with 18.9% for Chrohn's patients without SR-NCGS; (P = 0.046). Crohn's disease patients with SR-NCGS showed higher overall scores on the Crohn's Disease Activity Index (228.1 versus 133.3, P = 0.002) than those without SR-NCGS.
    The team analyzed 200 cases presenting with SR-NCGS, and found that 197 of them, or 98.5% were most likely diet-related IBS. However, 3 of the SR-NCGS patients (1.5%) actually had IBD, with all of the associated alarm symptoms, and/or abnormal blood parameters.
    The results show that SR-NCGS is not exclusive to IBS, but is also seen in some patients with IBD, which is a more severe, more debilitating condition.
    The team is calling for randomized studies to further delineate the nature of this relationship and clarify whether a gluten-free is appropriate for certain IBD patients.

    Celiac.com 06/19/2018 - Could baking soda help reduce the inflammation and damage caused by autoimmune diseases like rheumatoid arthritis, and celiac disease? Scientists at the Medical College of Georgia at Augusta University say that a daily dose of baking soda may in fact help reduce inflammation and damage caused by autoimmune diseases like rheumatoid arthritis, and celiac disease.
    Those scientists recently gathered some of the first evidence to show that cheap, over-the-counter antacids can prompt the spleen to promote an anti-inflammatory environment that could be helpful in combating inflammatory disease.
    A type of cell called mesothelial cells line our body cavities, like the digestive tract. They have little fingers, called microvilli, that sense the environment, and warn the organs they cover that there is an invader and an immune response is needed.
    The team’s data shows that when rats or healthy people drink a solution of baking soda, the stomach makes more acid, which causes mesothelial cells on the outside of the spleen to tell the spleen to go easy on the immune response.  "It's most likely a hamburger not a bacterial infection," is basically the message, says Dr. Paul O'Connor, renal physiologist in the MCG Department of Physiology at Augusta University and the study's corresponding author.
    That message, which is transmitted with help from a chemical messenger called acetylcholine, seems to encourage the gut to shift against inflammation, say the scientists.
    In patients who drank water with baking soda for two weeks, immune cells called macrophages, shifted from primarily those that promote inflammation, called M1, to those that reduce it, called M2. "The shift from inflammatory to an anti-inflammatory profile is happening everywhere," O'Connor says. "We saw it in the kidneys, we saw it in the spleen, now we see it in the peripheral blood."
    O'Connor hopes drinking baking soda can one day produce similar results for people with autoimmune disease. "You are not really turning anything off or on, you are just pushing it toward one side by giving an anti-inflammatory stimulus," he says, in this case, away from harmful inflammation. "It's potentially a really safe way to treat inflammatory disease."
    The research was funded by the National Institutes of Health.

    Celiac.com 06/18/2018 - Celiac disease has been mainly associated with Caucasian populations in Northern Europe, and their descendants in other countries, but new scientific evidence is beginning to challenge that view. Still, the exact global prevalence of celiac disease remains unknown.  To get better data on that issue, a team of researchers recently conducted a comprehensive review and meta-analysis to get a reasonably accurate estimate the global prevalence of celiac disease. 
    The research team included P Singh, A Arora, TA Strand, DA Leffler, C Catassi, PH Green, CP Kelly, V Ahuja, and GK Makharia. They are variously affiliated with the Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Lady Hardinge Medical College, New Delhi, India; Innlandet Hospital Trust, Lillehammer, Norway; Centre for International Health, University of Bergen, Bergen, Norway; Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Gastroenterology Research and Development, Takeda Pharmaceuticals Inc, Cambridge, MA; Department of Pediatrics, Università Politecnica delle Marche, Ancona, Italy; Department of Medicine, Columbia University Medical Center, New York, New York; USA Celiac Disease Center, Columbia University Medical Center, New York, New York; and the Department of Gastroenterology and Human Nutrition, All India Institute of Medical Sciences, New Delhi, India.
    For their review, the team searched Medline, PubMed, and EMBASE for the keywords ‘celiac disease,’ ‘celiac,’ ‘tissue transglutaminase antibody,’ ‘anti-endomysium antibody,’ ‘endomysial antibody,’ and ‘prevalence’ for studies published from January 1991 through March 2016. 
    The team cross-referenced each article with the words ‘Asia,’ ‘Europe,’ ‘Africa,’ ‘South America,’ ‘North America,’ and ‘Australia.’ They defined celiac diagnosis based on European Society of Pediatric Gastroenterology, Hepatology, and Nutrition guidelines. The team used 96 articles of 3,843 articles in their final analysis.
    Overall global prevalence of celiac disease was 1.4% in 275,818 individuals, based on positive blood tests for anti-tissue transglutaminase and/or anti-endomysial antibodies. The pooled global prevalence of biopsy-confirmed celiac disease was 0.7% in 138,792 individuals. That means that numerous people with celiac disease potentially remain undiagnosed.
    Rates of celiac disease were 0.4% in South America, 0.5% in Africa and North America, 0.6% in Asia, and 0.8% in Europe and Oceania; the prevalence was 0.6% in female vs 0.4% males. Celiac disease was significantly more common in children than adults.
    This systematic review and meta-analysis showed celiac disease to be reported worldwide. Blood test data shows celiac disease rate of 1.4%, while biopsy data shows 0.7%. The prevalence of celiac disease varies with sex, age, and location. 
    This review demonstrates a need for more comprehensive population-based studies of celiac disease in numerous countries.  The 1.4% rate indicates that there are 91.2 million people worldwide with celiac disease, and 3.9 million are in the U.S.A.

    Celiac.com 06/15/2018 - There seems to be widespread agreement in the published medical research reports that stuttering is driven by abnormalities in the brain. Sometimes these are the result of brain injuries resulting from a stroke. Other types of brain injuries can also result in stuttering. Patients with Parkinson’s disease who were treated with stimulation of the subthalamic nucleus, an area of the brain that regulates some motor functions, experienced a return or worsening of stuttering that improved when the stimulation was turned off (1). Similarly, stroke has also been reported in association with acquired stuttering (2). While there are some reports of psychological mechanisms underlying stuttering, a majority of reports seem to favor altered brain morphology and/or function as the root of stuttering (3). Reports of structural differences between the brain hemispheres that are absent in those who do not stutter are also common (4). About 5% of children stutter, beginning sometime around age 3, during the phase of speech acquisition. However, about 75% of these cases resolve without intervention, before reaching their teens (5). Some cases of aphasia, a loss of speech production or understanding, have been reported in association with damage or changes to one or more of the language centers of the brain (6). Stuttering may sometimes arise from changes or damage to these same language centers (7). Thus, many stutterers have abnormalities in the same regions of the brain similar to those seen in aphasia.
    So how, you may ask, is all this related to gluten? As a starting point, one report from the medical literature identifies a patient who developed aphasia after admission for severe diarrhea. By the time celiac disease was diagnosed, he had completely lost his faculty of speech. However, his speech and normal bowel function gradually returned after beginning a gluten free diet (8). This finding was so controversial at the time of publication (1988) that the authors chose to remain anonymous. Nonetheless, it is a valuable clue that suggests gluten as a factor in compromised speech production. At about the same time (late 1980’s) reports of connections between untreated celiac disease and seizures/epilepsy were emerging in the medical literature (9).
    With the advent of the Internet a whole new field of anecdotal information was emerging, connecting a variety of neurological symptoms to celiac disease. While many medical practitioners and researchers were casting aspersions on these assertions, a select few chose to explore such claims using scientific research designs and methods. While connections between stuttering and gluten consumption seem to have been overlooked by the medical research community, there is a rich literature on the Internet that cries out for more structured investigation of this connection. Conversely, perhaps a publication bias of the peer review process excludes work that explores this connection.
    Whatever the reason that stuttering has not been reported in the medical literature in association with gluten ingestion, a number of personal disclosures and comments suggesting a connection between gluten and stuttering can be found on the Internet. Abid Hussain, in an article about food allergy and stuttering said: “The most common food allergy prevalent in stutterers is that of gluten which has been found to aggravate the stutter” (10). Similarly, Craig Forsythe posted an article that includes five cases of self-reporting individuals who believe that their stuttering is or was connected to gluten, one of whom also experiences stuttering from foods containing yeast (11). The same site contains one report of a stutterer who has had no relief despite following a gluten free diet for 20 years (11). Another stutterer, Jay88, reports the complete disappearance of her/his stammer on a gluten free diet (12). Doubtless there are many more such anecdotes to be found on the Internet* but we have to question them, exercising more skepticism than we might when reading similar claims in a peer reviewed scientific or medical journal.
    There are many reports in such journals connecting brain and neurological ailments with gluten, so it is not much of a stretch, on that basis alone, to suspect that stuttering may be a symptom of the gluten syndrome. Rodney Ford has even characterized celiac disease as an ailment that may begin through gluten-induced neurological damage (13) and Marios Hadjivassiliou and his group of neurologists and neurological investigators have devoted considerable time and effort to research that reveals gluten as an important factor in a majority of neurological diseases of unknown origin (14) which, as I have pointed out previously, includes most neurological ailments.
    My own experience with stuttering is limited. I stuttered as a child when I became nervous, upset, or self-conscious. Although I have been gluten free for many years, I haven’t noticed any impact on my inclination to stutter when upset. I don’t know if they are related, but I have also had challenges with speaking when distressed and I have noticed a substantial improvement in this area since removing gluten from my diet. Nonetheless, I have long wondered if there is a connection between gluten consumption and stuttering. Having done the research for this article, I would now encourage stutterers to try a gluten free diet for six months to see if it will reduce or eliminate their stutter. Meanwhile, I hope that some investigator out there will research this matter, publish her findings, and start the ball rolling toward getting some definitive answers to this question.

    Celiac.com 06/14/2018 - Refractory celiac disease type II (RCDII) is a rare complication of celiac disease that has high death rates. To diagnose RCDII, doctors identify a clonal population of phenotypically aberrant intraepithelial lymphocytes (IELs). 
    However, researchers really don’t have much data regarding the frequency and significance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. Such data could provide useful comparison information for patients with RCDII, among other things.
    To that end, a research team recently set out to try to get some information about the frequency and importance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. The research team included Shafinaz Hussein, Tatyana Gindin, Stephen M Lagana, Carolina Arguelles-Grande, Suneeta Krishnareddy, Bachir Alobeid, Suzanne K Lewis, Mahesh M Mansukhani, Peter H R Green, and Govind Bhagat.
    They are variously affiliated with the Department of Pathology and Cell Biology, and the Department of Medicine at the Celiac Disease Center, New York Presbyterian Hospital/Columbia University Medical Center, New York, USA. Their team analyzed results of TCR-GR analyses performed on SB biopsies at our institution over a 3-year period, which were obtained from eight active celiac disease, 172 celiac disease on gluten-free diet, 33 RCDI, and three RCDII patients and 14 patients without celiac disease. 
    Clonal TCR-GRs are not infrequent in cases lacking features of RCDII, while PCPs are frequent in all disease phases. TCR-GR results should be assessed in conjunction with immunophenotypic, histological and clinical findings for appropriate diagnosis and classification of RCD.
    The team divided the TCR-GR patterns into clonal, polyclonal and prominent clonal peaks (PCPs), and correlated these patterns with clinical and pathological features. In all, they detected clonal TCR-GR products in biopsies from 67% of patients with RCDII, 17% of patients with RCDI and 6% of patients with gluten-free diet. They found PCPs in all disease phases, but saw no significant difference in the TCR-GR patterns between the non-RCDII disease categories (p=0.39). 
    They also noted a higher frequency of surface CD3(−) IELs in cases with clonal TCR-GR, but the PCP pattern showed no associations with any clinical or pathological feature. 
    Repeat biopsy showed that the clonal or PCP pattern persisted for up to 2 years with no evidence of RCDII. The study indicates that better understanding of clonal T cell receptor gene rearrangements may help researchers improve refractory celiac diagnosis.
