1,5-Anhydroglucitol, an indicator of short term glycaemic control, is the most discriminatory metabolomic marker in adolescents with type 1 diabetes compared to control subjects

Methods Design Case control study. Setting Tertiary paediatric hospital clinic. Population 27 (14F/13M) adolescents with T1D (age (median, interquartile range) 15.5, 14.7-16.4 years; duration 7.7; 6.0-11.8 years; HbA1c 9.1, 8.1-10.1%); glucose 13.35 (7.60-17.85) and 27 (14F/13M) control participants (age 15.1, 14.4-16.8 years). BMI was u003c95 percentile. Measures Fasting plasma and urine metabolomes were profiled by GC-MS and compared between cohorts. Statistics Univariate comparisons:-Spearman correlations, t-tests/Wilcoxon rank sum tests. Multivariate comparisons:-PCA, OPLS-DA and OPLS.
