84. The coenzyme Q10 content of food supplementsIgor Pravst, Katja Žmitek, 2011, original scientific article Abstract: In the European Union (EU), food supplements are regulated as food and their use is expanding rapidly. There is no enforcement to ensure that good manufacturing practices (GMPs) are followed during production but manufacturers are fully responsible for their products. Recently, the safety and quality of supplements available in the market has come into question. In our surveillance, we examined coenzyme Q10 content of 58 food supplements available in three EU member states or from Internet stores using high-performance liquid chromatography methodology. While some of the tested supplements contained almost exactly the same quantity of active ingredient as labelled, one-third of the products contained <70% of the labelled content. In the food supplements obtained online the medium content was lower than in the products purchased in pharmacies. To protect the consumer and assure the safety and quality of products, the market authorities need to exert better control. In addition, it would make sense to enforce additional requirements to ensure GMPs are followed in the manufacturing process of food supplements.

86. Polygenic score from MODY genes is associated with type 1 diabetes and disease characteristicsEulalia Catamo, Andrea Conti, Roberto Franceschi, Klemen Dovč, Camilla Morosini, Davide Tinti, Tadej Battelino, 2025, original scientific article Abstract: Aims: This study evaluates the contribution of common variants in Maturity-Onset Diabetes of the Young (MODY) genes on type 1 diabetes (T1D), using a polygenic score (PGS) approach. Methods: 485 children and youth diagnosed with T1D from at least 1 year and 271 healthy controls (HC) were recruited. Personal information (i.e. age, sex, height, weight) were collected for each participant, and clinical information (i.e. age at diagnosis, disease duration, presence of autoantibodies and ketoacidosis at onset (DKA)) were also obtained for T1D subjects. Participants were genotyped using Illumina Infinium Global Screening Array. PGS based on Single Nucleotide Polymorphisms (SNPs) in 16 MODY genes were developed. The association of this PGS with T1D susceptibility and clinical disease characteristics was assessed by regression analysis. Results: A PGS including 335 SNPs in MODY genes discriminates T1D from HC (AUC = 60.1%, AIC = 787.6). This PGS was significantly higher in T1D compared to HC (p-value = 0.0004, pseudo-R2 = 2.85%). Moreover, regression analysis between PGS and T1D clinical characteristics showed higher PGS values in T1D subjects with zinc transporter 8 autoantibodies (ZnT8A) compared with T1D subjects without ZnT8A (p-value = 0.04). A similar trend was also observed for antibodies directed against glutamic acid decarboxylase (GADA), although the association did not reach statistical significance (p-value = 0.06). Conclusions: Our study suggests that a polygenic approach based on MODY genes may discriminate T1D from HC and may contribute to patient stratification, helping to better understand T1D heterogeneity.
