Background: Although coeliac disease is common worldwide, little is known regarding screening patterns in unselected populations, and on real-life adherence to professional guidelines for coeliac disease diagnosis and management.
Objective: To explore current practices in the diagnosis and management of coeliac disease, using data from a large Health Maintenance Organization in Israel that covers 54% of the population.
Methods: A population-based electronic database of about 4.5 million individuals was reviewed during the period of 1 January 2008 to 31 December 2015. Rates and results of coeliac disease serology testing and endoscopy procedures were examined. Subgroup analysis was performed by age, sex, ethnicity and socioeconomic status.
Results: Coeliac disease serology cumulative testing rate was 17.1% and 8.9% in the paediatric and adult population, respectively. The cumulative incidence of positive coeliac disease serology was 0.45% in children and 0.17% in adults, and was associated with age, sex, ethnicity and socioeconomic status sub-groups (P-value < 0.01). Gastrointestinal endoscopies were not subsequently performed in 44.1% of children and 47.1% of adults with positive coeliac disease serology. Within the study period, 36% of children and 56% of adults never achieved coeliac disease serology normalization.
Conclusion: In a large real-life database, screening for coeliac disease was common. However, confirmatory intestinal biopsies were under-utilized, and coeliac disease serology often remained positive over a long period time in both children and adults.
