Utility of apolipoprotein ratio in predicting metabolic risk and microvascular complications in Indian children and young adults with type 1 diabetes mellitus

Abstract

AbstractObjectivesTo assess the relationship of apolipoproteins with glycemic control and insulin resistance (IR) in Indian children and youth with type-1 diabetes (T1D) and to assess its utility in predicting metabolic risk (MR) and microvascular complications in these subjects.MethodsThis cross-sectional study included 152 participants aged 6–23 years with T1D. Demographic, anthropometric, clinical, biochemical and body composition data were obtained using standard protocols. IR was calculated using estimated glucose disposal rate (eGDR) and metabolic syndrome (MS) was diagnosed using the international diabetes federation consensus definition 2017.ResultsApolipoprotein ratio in subjects with T1D had negative and positive correlation with eGDR and HbA1crespectively. Positive correlation of Apolipoproten B and apolipoprotein ratio with urinary albumin creatinine ratio is noted. The ratio had area under curve of 0.766 and 0.737 to predict MR and microvascular complications respectively. The ratio cut-off of 0.536 yielded 77.1 % sensitivity and 61 % specificity to predict MR. On adding the apolipoprotein ratio as a predictor to the regression model developed to predict MR, the R2and accuracy improved.ConclusionsThe apolipoprotein ratio had significant correlation with IR, microalbuminuria and glycaemic control. The ratio also predicts risk of development of microvascular complications and maybe used to predict MR in subjects with T1D.
