Risk factors for CVD include an elevation of LDL (LDLp) and small HDL (sHDLp) particles, and a decrease in reverse cholesterol transport i.e. HDL-cholesterol efflux capacity (CEC). Our objective was to compare lipoprotein particles and CEC between T1DM and healthy controls (HC) and to explore the associations between NMR lipid particles and cholesterol efflux.Abstract: METHODS: 78 patients with T1DM and 59 HC underwent fasting lipoprotein profile testing by NMR and measurements of CEC by cell-based method. The associations between NMR lipid particles with CEC were analyzed using multivariable linear regression models.Abstract: RESULTS: Youth with T1DM had higher total LDLp 724 [(563-985) vs 622 (476-794) nmol/L (P = 0.011)] (Maahs et al. in Circulation 130(17):1532-58, 2014; Shah et al. in Pediatr Diabetes 16(5):367-74, 2015), sHDLp [11.20 (5.7-15.3) vs 7.0 (3.2-13.1) mumol/L (P = 0.021)], and lower medium HDLp [11.20 (8.5-14.5) vs 12.3 (9-19.4), (P = 0.049)] and lower CEC (0.98 +/- 0.11% vs 1.05 +/- 0.15%, P = 0.003) compared to HC. Moreover, CEC correlated with sHDLp (beta = - 0.28, P = 0.045) and large HDLp (beta = 0.46, P < 0.001) independent of age, sex, ethnicity, BMIz, HbA1c, hsCRP and total HDLp in the diabetic cohort.Abstract: CONCLUSIONS: Youth with T1DM demonstrated a more atherogenic profile including higher sHDL and LDLp and lower CEC. Future efforts should focus on considering adding lipoprotein particles and CEC in CVD risk stratification of youth with T1DM. Trial registration Clinical Trials Registration Number NCT02275091.
