S Gatti et al. Clin Gastroenterol Hepatol 2020; 18: 596-603. The authors screened 4570 children (5-11 year olds) from 2015-16; this study included 80% of eligible children from two metropolitan areas in Italy.
- 77 cases of children met diagnostic criteria for celiac disease (54 met criteria and 23 prior known cases)
- Prevalence in this population, overall, was 1.58% (2015-16); in 1993-95, the adjusted prevalence was 0.88%
- Celiac disease autoimmunity was noted in 96 .
- 1960 (43%) had celiac disease associated haplotypes
A Myleus et al. Clin Gastroenterol Hepatol 2020; 18: 562-73. In this systematic review, 49 studies (out of initial 703) were included in final analysis to determine risk factors and outcomes with nonadherence to treatment with gluten free diet.
- Large range of adherence rates: 23% to 98% (median rates were 75-87%).
- Adolescents were at increased risk of non-adherence
- Children whose parents had good knowledge had higher adherence rates
- There was not improved adherence over time, despite improvement in palatable gluten-free foods.
One of the other findings in the study was the lack of consensus about what defines strict adherence and how to measure it.
My take: The first study is in agreement with many others which have demonstrated higher prevalence of celiac disease now compared to previously. The second study shows that adherence with treatment is highly variable and difficult to measure.
