Celiac disease is defined as an autoimmune enteropathy with malabsorption of gluten protein. In recent studies, it has been stated that in individuals diagnosed with celiac disease, intestinal epithelial barrier integrity is impaired. Increased zonulin concentration in blood is considered as an indicator of increased intestinal permeability.
Gluten-free diet is the only treatment of celiac disease. Adherence to gluten free diet provides decreasing of intestinal permeability however gluten free diet has different aspects on nutritional status and health related quality of life in people with celiac disease.
The aim of this study is to determine nutritional status, intestinal permeability and quality of life in people with celiac disease. In the study,it primarily hypothesized that celiac patients noncompliant to gluten-free diet may have increased circulating levels of zonulin and increased intestinal permeability compared to celiac patients compliant to gluten-free diet.
Celiac disease is defined as an autoimmune enteropathy that progresses with malabsorption of gluten protein found in wheat, barley, rye and small intestinal mucosal inflammation in individuals with genetic predisposition. Disruption of intestinal barrier integrity play role in the pathogenesis of celiac disease. Zonulin levels increase in the disruption of intestinal permeability in celiac patients.
At the present, the only treatment of celiac disease is life-long gluten-free diet and it requires strict gluten elimination . With compliance to gluten-free diet, thickening of intestinal mucosal layer, decreasing of villi atrophy and decreasing of transcellular infiltration are observed. In other studies, it was stated that adherence to gluten-free diet can repair intestinal permeability and decrease zonulin levels.
While compliance to gluten-free diet is a key point to prevent progression of the disease, nutritional quality of the gluten-free diet affects nutritional status of patients. Moreover,restricted diets in terms of energy or various nutrients affect health-related quality of life. In studies examining all aspects of celiac disease, it has been stated that health-related factors reduce the quality of life in celiac patients.
In conclusion, this study aims to investigate the presence of intestinal permeability with serum zonulin levels in celiac patients, to evaluate nutritional status of patients with anthropometric measurements and food consumption records, and to determine quality of life of patients with validated celiac disease questionnaire. This study in Turkey, is also first study that investigate all these three factors.

Body weight (kg), fat mass (kg) and muscle mass (kg) of each patient were measured with a bioelectrical impedance analysis (BIA) based body composition analyzer. |
| 1 day |
| Body height, waist and hip circumference measurements of people with celiac disease | Certain anthropometric measurements of each patient were taken. Height (cm) was measured with a stadiometer. Tape measurements of waist circumference (cm) and hip circumference (cm) were recorded. | 1 day |
| Calculation of waist circumference to hip circumference ratio of people with celiac disease | The ratio of waist circumference to hip circumference was calculated by dividing waist circumference measurement value (cm) to hip circumference measurement value (cm). | 1 day |
| Quality of life of people with celiac disease | Celiac disease quality of life questionnaire specific to Turkish celiac population was performed. The questionnaire includes twenty eight questions and total point of questionnaire is between 0-196.
