- Children's plasma metabolome, especially lipidome reflects gene regulation and dietary exposures, heralding the development of islet autoantibodies (IA) and type 1 diabetes (T1D). The TEDDY study enrolled 8676 newborns by screening HLA-DR-DQ genotypes at six clinical centers in four countries; profiled metabolome and measured concentrations of ascorbic acid, 25-hydroxyvitamin D (25(OH)D), erythrocyte membrane fatty acids following birth until IA seroconversion under nested case-control design. We grouped children having an initial autoantibody only against insulin (IAA-first) or glutamic acid decarboxylase (GADA-first) by unsupervised clustering of temporal lipidome, identifying a subgroup of children having early onset of each initial autoantibody, i.e., IAA-first by 12 months and GADA-first by 21 months, consistent with population-wide early seroconversion age. Differential analysis showed that infants having reduced plasma ascorbic acid and cholesterol experienced IAA-first earlier, while early onset of GADA-first was preceded by reduced sphingomyelins at infancy.
