Abstract:
Lower SUMOD correlates with decreasing kidney function and atherosclerosis in adults with T1D, but its relationship with markers of arterial stiffness in youth with T1D is unknown. We sought to evaluate the relationship between SUMOD and central arterial stiffness in youth with T1D. Participants (n=49, 12-21 years old, 51% female, BMI 25.2±4.6 kg/m2, mean HbA1c8.6±1.4) were enrolled in EMERALD, a randomized controlled trial of metformin in youth with T1D. Post-hoc SUMOD was measured using Euroimmun ELISA kits from serum from the baseline visit. Ascending (AA) and descending aortic (DA) stiffness (pulse wave velocity [PWV] and strain) were determined by MRI at baseline and 3 months of follow-up. SUMOD positively correlated with AA strain (r: 0.37, p=0.04) and negatively with AA PWV (r: -0.41, p=0.03). According to SUMOD tertiles, participants in the lower tertile had higher AA PWV vs. the middle and high tertiles (Figure). Lower baseline SUMOD also predicted worsening in AA PWV over 3 months (β±SE: -0.04±0.01, p=0.03) adjusting for age, sex, baseline AA PWV, treatment group (metformin vs. placebo) and estimated glomerular filtration rate. In T1D youth, decreased SUMOD is associated with increased aortic stiffness. Further research is needed in T1D youth to understand the pathogenesis of SUMOD in cardiovascular disease. Disclosure P.
