Lipoprotein subclasses and early kidney dysfunction in young type 1 diabetes mellitus patients.

Impaired glycolipid metabolism can induce vascular injury and plaque formation. It is important to investigate the associations between carotid plaque progression and lipid-lowering goal achievement and cardiovascular disease.Diabetic patients who underwent at least 2 carotid ultrasound scans with intervals ≥0.5 years and were hospitalized in the Department of Endocrinology at Sun Yat-sen Memorial Hospital were included. Patients were divided into 3 groups based on carotid plaque progression: the persistent plaque absence, new-onset plaque and persistent plaque presence groups. The primary outcomes were CHD and stroke, while the secondary outcomes were low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) goal achievement.There were 304 diabetic patients included, with a median follow-up period of 2.15 years. In multivariable logistic regression analysis, persistent plaque presence was positively associated with a 2.285-fold increase in coronary heart disease (CHD) prevalence, while new-onset plaque was associated with a 3.225-fold increase in stroke prevalence compared to persistent plaque absence in patients with follow-up periods ≥ 0.5 years. The association remained significant in patients with a follow-up period ≥ 1 year and ≥2 years. The velocity of average plaque length change was independently associated with increased ΔLDL-C (last – goal) (β = 0.073, P = 0.048).Carotid plaque progression had long-term association with CHD and stroke starting from 0.5 years, while the velocity of average plaque length associated with increased ΔLDL-C (last – goal) might reflect patient response to statins. Repeated carotid plaque measurements might guide lipid-lowering therapies.
