Brief Summary

Celiac disease (CD) was diagnosed for years almost exclusively in children. This is due to the fact that in adulthood it manifests in a much more attenuated form, while the classic form with severe diarrhea, malnutrition and dehydration is observed almost exclusively in children. Classic studies, carried out prior to the widespread use of serology as a CD diagnostic tool, already showed that there is variability in gluten sensitivity and that in a non-negligible proportion of cases (10%) gluten sensitivity appears to be transient. Subsequent studies, including patients diagnosed by serology or population screening studies, suggest that progression to gluten latency or tolerance may occur in a higher proportion of patients, ranging from 20 to 50% depending on the geographical region. In the first decade of the 2000s, the researchers group performed a prevalence observational cross-sectional study survey in Catalonia (autonomous region in the northeast of Spain) that accurately reflected the distribution of the reference Catalan population in terms of sex and age. The results showed a drastic and significant drop in the prevalence of CD disease in relation to age, with the prevalence of CD in children being 5 times higher than adults (1:71 vs. 1:357). Strikingly, the reduction in prevalence was especially notable in the first 4 years of life. Two possibilities were proposed to explain this unexpected finding in a disease that is lifelong: 1) The existence of an environmental effect (cohort effect) acting as a disease trigger in early childhood during the study period (e.g., bacterial or viral infections, vaccines, food policies related to gluten introduction, use of antibiotics, etc.). 2) The appearance of age-related tolerance to gluten in a proportion of cases. Interestingly, it has been suggested that immunological tolerance might be more frequent in children diagnosed with CD before the age of two. The aims of the present epidemiological study are: 1) to determine the prevalence of CD in Catalonia in children under 5 years of age and compare it with the results obtained in the previous 2004-2007 study; 2) to investigate the potential effect of environmental factors on disease prevalence; and 3) to evaluate longitudinally the appearance of tolerance to gluten in the CD cases detected. Therefore, this study has been designed using exactly the same CD screening methodology and reproducing the reference population in the same geographical area as the previous 2004-2007 study.
