Core Tip
Core Tip: Inadequately managed celiac disease can lead to health complications. However, there are limited published data on real-world monitoring and outcomes for patients with celiac disease. In this real-world study, country/site-specific differences in the routine monitoring of patients after diagnosis were evident, including differences in the frequency of follow-up biopsy. A large proportion of patients continued to have villous atrophy and symptoms after diagnosis and, therefore, there is a continued need for more routine follow-up assessments, including mucosal assessments of celiac disease activity.
