Evaluation of mucosal status in the follow-up of pediatric patients with celiac disease: the role of serology
2022
Overview
Recent guidelines suggest non-biopsy serology–based approach for the diagnosis of celiac disease; however, there is no evidence-based data regarding noninvasive follow-up of mucosal healing. The aim of this study is to investigate the efficacy of serology in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. This is a validation study conducted at a university hospital. Patients who had biopsy proven celiac disease (Marsh III) at diagnosis, and had been followed-up for at least 12 months, were prospectively evaluated with duodenal biopsies. tTG-IgA and EMA tests were performed on the day of endoscopy. One hundred four patients with a mean age of 7.4 ± 4.02 years were included in the study. The sensitivity and specificity of tTG-IgA were 85.2% and 61% respectively, with a high negative predictive value (NPV) of 92.2% but a very low positive predictive value (PPV) of 43.4%. We found that a cutoff value of 68.5 U/mL for tTG-IgA had a sensitivity, specificity of 85.2% and 85.7% respectively. The AUC was 0.891. The sensitivity and specificity of EMA was 77.8% and 87% respectively, with a high NPV of 91.8% but low PPV of 67.7%.Conclusion: This study suggests that negative tTG-IgA and/or EMA can be used as an indicator of mucosal improvement in the follow-up of pediatric patients with celiac disease. However, positive serology (i.e., < 10 × ULN) may be misleading in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. What is Known:• The tissue transglutaminase IgA (tTG-IgA) and endomysium IgA (EMA) tests are widely used, sensitive and reliable diagnostic tests, but their role in monitoring adherence to dietary treatment in celiac patients has not yet been demonstrated.• There is still no reliable and non-invasive marker of persistent villous atrophy or mucosal recovery.What is New:• Negative celiac serology detected in the follow-up of pediatric patients with celiac disease was successful in demonstrating histopathological mucosal healing.• Positive celiac serology, which is highly reliable in the diagnosis of celiac disease, has not been successful in reflecting mucosal status when used in the follow-up of pediatric patients with celiac disease.
