Introduction: Celiac disease is an immune-mediated systemic disease that occurs in genetically predisposed individuals. It is caused by an abnormal reaction of intestinal mucosa to gluten, protein found in wheat, barley and rye. Disease is manifested by abundant, frequent stools, malabsorption, fatigue and weight loss. It is diagnosed by clinical examination, antibody testing, histological findings of the atrophy of the intestinal mucosa and the response to gluten-free diet. Celiac disease is often occurring with some other pathological conditions, especially autoimmune diseases such as diabetes and autoimmune thyroid disease. ----- Aim: To determine the number of people with thyroid disease in our sample of patients diagnosed with celiac disease. ----- Methods: A retrospective, cross-sectional study of 203 patients, conducted in the period from 01.01.2013 to 01.01.2019 and summary data analysis including age, gender and documented pathological changes of the thyroid gland. ----- Results: 165 women and 38 men, the average age of 39.4 years, age ranging from 20 to 80 years, with diagnosed celiac disease. Thyroid pathology was found in 11 people, 7 people with hypothyroidism and a prevalence of 3.45% (95% CI 1.68 – 6.95), 6 people with Hashimoto’s thyroiditis and a prevalence of 2.95% (95% CI 1.36 – 6.29), 1 person with thyroidectomy and 1 person with thyroid tumor ( Tm. Folliculare gl. Thyreoideae L. Dex.). No person was found with hyperthyroidism or with Graves (Basedow’s) disease. ----- Conclusion: 11 people were found with thyroid diseases, the prevalence of thyroid disease in our group of patients with celiac disease is 5.42% (95% CI 3.05 – 9.44).
