Pediatric and adult patients diagnosed with celiac disease are not at higher risk of contracting SARS-CoV-2 We read the study by Lionetti et al 1 regarding the prevalence of SARS-CoV-2 (COVID-19) in Italian children with celiac disease with great interest. The prevalence and clinical features of COVID-19 were investigated through a phone-based survey that involved 387 pediatric patients with a diagnosis of celiac disease based on ESPGHAN criteria. The results were compared with data from the Italian National Institute of Health and the Marche regional government. The survey did not report any positive case of COVID-19 in pediatric patients with celiac disease.

The results are in agreement with our previously published multinational study 2 involving 18,000 participants with and without celiac disease from over 10 different countries. This large study included over 10,000 patients with celiac disease, and evaluated the risk of contracting COVID-19, mainly in adult patients 2 . We are pleased that the study of Lionetti et al 1 , which specifically investigated infection prevalence in Italian children, strengthens our conclusions. Taken together the results strongly support the notion that, in both pediatric and adult populations, there is no increased risk of contracting COVID-19 in patients that have been diagnosed with celiac disease. The combined findings are reassuring, particularly since a study recently reported elderly and female patients feeling more vulnerable because they had celiac disease 3 . The results are also important for physicians, to reassure patients with celiac disease under their care.

Although it is unclear whether the results from this pediatric survey 1 can be generalized to other countries affected in a variety of different ways (time, government response, socioeconomic status, etc), by the pandemic, the data provides a key starting point for future studies. More importantly, both studies 1,2 followed a cross-sectional design in patients that had already developed celiac disease, and it will be therefore important in the future to investigate post-infective consequences in the general population or in patients at risk of developing celiac disease.
