Celiac Disease Clinical Trial
Official title:
Screen-detected Coeliac Disease. Prevalence and Impact on Gastrointestinal Symptoms and Quality of Life
The purpose of this study is to determine the prevalence of previously undiagnosed coeliac disease based on a health survey from Tromsø, Norway. Moreover, the health impact of undiagnosed coeliac disease will be examined.
Few population-based studies have examined the prevalence of coeliac disease and the impact
of undiagnosed coeliac disease on health. Moreover, the number of people with undiagnosed
coeliac disease is much higher than the number who know their diagnosis.
The purpose of this study is to determine the prevalence of coeliac disease and the impact of
undiagnosed coeliac disease on health.
In a health survey of the population of Tromsø Norway, serological markers of coeliac disease
(transglutaminase 2, TG2 and deamidated gliadin antibody test) have been analyzed.
Individuals with increased level of one of these markers, will be invited for upper endoscopy
with small bowel biopsy examination to confirm the diagnosis of coeliac disease. All persons
with screen detected coeliac disease, will be advised to start a gluten free diet.
Health status and Quality of Life will be examined by means of the Gastrointestinal Symptoms
Rating Scale (GSRS) and the Psychological General Well-Being Index (PGWBI) respectively.
1. At baseline GSRS and PGWBI will be analyzed in persons with screen detected and biopsy
verified coeliac disease and compared with a group of healthy control persons from the
health-survey cohort.
2. In a prospective study of the persons with screen detected coeliac disease, health
status (GSRS) and Quality of Life will be compared before and after one year on a gluten
free diet.
