Celiac.com 11/28/2011 - Celiac disease often results in "leaky" intestinal mucosa. This development may involve changes in hydrophobicity of the mucus surface barrier along with changes of the epithelial barrier. A team of researchers recently compared bio-physical aspects of gastrointestinal mucosa of celiac patients with control subjects, along with the effects of gluten free diet on each group. The research team included Stefania Bertolazzi, Francesco Lanzarotto, Barbara Zanini, Chiara Ricci, Vincenzo Villanacci, and Alberto Lanzini. The team set out to compare duodenal hydrophobicity as an index of mucus barrier integrity in 38 patients studied before and 68 patients during gluten-free diet, and in 90 control subjects. They also checked for regional differences of hydrophobicity in the gastro-intestinal tract. The team gauged hydrophobicity by measuring the contact angle (CA) (Rame Hart 100/10 goniometer) created by a single drop of water applied to intestinal mucosal biopsies. Once the team pooled the results and evaluated the control groups, patients with histologically normal duodenal biopsies showed significantly higher CA (620 + 90) than patients with biopsies showing Marsh 1-2 (580 + 100; p<0.02) and Marsh 3 lesions (570+ 100; p<0.02). Among the control group, the action sequence of hydrofobicity along the gastrointestinal tract follows the pattern: gastric antrum> corpus> rectum> duodenum> oesophagus> ileum. From these results, the team concludes that people with celiac disease experience reduced hydrophobicity of duodenal mucous layer, and a reduced ability to repel luminal contents. This may may contribute to the increased intestinal permeability seen in celiac disease. This change in hydrofobicity corresponds to the severity of the mucosal lesions in the patient, and is not completely reversed by gluten-free diet.

Scott Adams posted an article in Celiac Disease & Gluten Intolerance ResearchThe following was sent to me from Rio de Janeiro by Dr. José Cesar da Fonseca Junqueira. If you have any questions you can e-mail him at: email@example.com Rio de Janeiro - 05/27/96 - Celiac Disease. A Comparative study of two periods. Junqueira JC, CalÃ§ado AC, Percope S. 1996 Federal University of Rio de Janeiro Martagão Gesteira - Institute of Pediatrics. The aim of this study was to compare cases of celiac disease diagnosed in outpatients with malabsortion cases. The study was conducted at the Pediatric Gastroenterology Service of the Pediatric Institute Martagão Gesteira at the Federal University of Rio de Janeiro Brazil. It was done in two phases: from 1975 -1984 and from 1985 - 1994 (group 1, N=31 and group 2, N=21). Patients were selected based on the results of jejunal biopsy (group IV) and the favorable reaction to a gluten free diet. Data from the first interview (age, sex, nutritional status and prevalent symptoms) were analyzed. The number of biopsies and the level of compliance with the diet were also observed. The data collected was processed in a computer using EPI INFO 6.03 (January 1996)as software. The frequency of celiac disease over the studied years was compared with international data. There were no significant differences between the two groups in our study. However, the cases free of gastroenterological symptoms (atypical celiac disease) were not observed. The average age difference between the groups (group um X=24,39 months; group 2 X=32,03) was not statistically significant. A bigger study must be carried out to prove this theory. The analysis of nutritional status of the groups reveals the existence of severely undernourished patients. The number of biopsies and the level of compliance with diet were similar in the two groups. The decrease in the number of cases as well the increase in the age of patients were observed in group 2. These phenomena were probably due to a delayed exposure to gluten and to the expansion of the period of breast feeding. Other causes should be analyzed in a bigger research program. The conclusion of this study shows that there has been no change in the clinical features of the disease and points to the need for serological screening so that the entire spectrum of the disease can be established. Both groups had malabsorption and were very under-nourished (over 45%). One patient was diagnosed as having Diabetes Mellitus several years after and an other one is under investigation for poliarthrites. Serological investigation is not available in our country. The final conclusion is that we must have such serological screening to know the real spectrum of the disease. Adult celiac disease is not diagnosed in our country, mainly because the adult doctors do not know the full spectrum of celiac disease. Ill be presenting this work as a thesis at the University on May 29, 1996.
New England Journal of Medicine October 19, 1995 -- Volume 333, Number 16 Celiac.com 10/25/1995 - According to an article published for the week of October 19, 1995 (Vol. 333, No. 16) in the New England Journal of Medicine, it is not a problem for celiacs to eat oats (non-contaminated, of course!). The article is based on a study conducted in Finland by a group of doctors who did very rigorous testing on adult celiacs and concluded that oats can, and should be included on the celiac diet (The lead doctor for the study is also a celiac). The following is a summary of the study: 52 celiacs in remission (on a gluten-free diet for more than a year) were given duodenal-biopsies, and then fed an average of 49.9 grams of oats per day for six months. They were again given biopsies, and none of the subjects were found to have any villi damage. There was also a group of 40 newly diagnosed celiacs who underwent the same procedures, except they were studied for 12 months rather than 6. The initial biopsies with this group showed significant villi damage due to the fact that they were still on a gluten-containing diet until they began the study. This group was fed an average of 46.6 grams of oats per day, and were given biopsies at 26 and 52 weeks. Their biopsies were almost normal at 26 weeks, which means their damaged villi were able to heal while eating oats daily. At the end of the year their biopsies showed no damage to their villi. The study DID NOT test people who had severe cases of celiac disease, and therefore cannot make recommendations with regard to them. Also, three people with dermatitis herpetiformis withdrew from the study because of an increase of itching, but none of them showed any signs of dermatitis. One person withdrew because of abdominal symptoms, but they did not exhibit damaged villi. Their conclusion: Our data suggest that most patients with celiac disease, whether in remission or newly diagnosed, can add moderate amounts of oats to their otherwise gluten-free diets without any harmful subjective side effects or laboratory abnormalities. Furthermore, among the newly diagnosed patients the improvement of mucosal architecture and the disappearance of mononuclear-cell infiltration were similar, regardless of the use of oats. -NEJM There is also an editorial from England which cites positive research which has been done there regarding oats. The NEJM is the Bible of medical research, with extensive peer reviews before publication.
