Jamnik J, et al. - Here, researchers ascertain the prevalence of positive coeliac disease (CD) serology in a population of Canadian adults living in Toronto and aim to figure out if the prevalence of CD seropositivity and predisposing human leucocyte antigen (HLA)-DQ2/DQ8 risk genotypes differ between major ethnocultural groups. The outcome revealed that the prevalence of positive CD serology among Canadian adults living in Toronto is likely ∼1%, with 87% of cases being undiagnosed. These outcomes recommend the requirement for better screening in high genetic risk groups.
