Rio de Janeiro - 05/27/96 - Celiac Disease. A Comparative study of two periods. Junqueira JC, Calçado 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 CD) 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.

The AGA/IgA and AGA/IgG tests are reliable and I am not sure why some consider them not as reliable. They are just the older versions of the current DGP testing, which is more sensitive than the AGA testing. I have full blown Celiac Disease and I failed both AGA tests at diagnosis by high numbe...

Whitepaw, I also meant to say that my friend who has been having gastritis issues since the winter (now it seems to be getting better after tapering off Lanzaprazole and introducing more natural remedies) told me that she used to feel acid in her stomach first thing, too. It is good to know that...

So I have another son with a different autoimmune disorder (jia). But my brother has type one diabetes which I've read is gene related to celiac. I myself have been tested for celiac twice because I have gastro issues with it but it has always been negative. Yes they said it may be while. H...

With omeprazole I never felt entirely good really - some time every day I felt off, but I think it might have been the bloating. Perhaps I never gave it long enough. Yet that nauseous feeling and diarrhea carried on for a few days after I stopped taking it. Now on day four of Ranitidine/Za...

Re: food diary. That is a really good way of keeping a food diary - I always thought it was a question of just scribbling everything down. But categorising things into what one can always tolerate, sometimes tolerate, never tolerate is such a good way of making things seem clearer. Re:...
