Association of remnant cholesterol with glycemic control and presence of microvascular complications in individuals with type 1 diabetes mellitus.

INTRODUCTION: This study examines the relationship between remnant cholesterol, glucose metrics, and chronic complications of type 1 diabetes in users of glucose monitoring systems. MATERIAL AND METHODS: Clinical variables and glucose metrics were collected from individuals using glucose sensors. Statistical models were employed to investigate the association of remnant cholesterol with glucose metrics, diabetic retinopathy, and diabetic nephropathy. RESULTS: A total of 383 individuals, aged 48.3 ±â€¯16.2 years, with 54.1% women, and a remnant cholesterol level of 16 ±â€¯10 mg/dL, were included. The results demonstrated that remnant cholesterol was associated with less time within the target range (p = 0.015) and more time above the target range (p = 0.003). Diabetic nephropathy was the only complication associated with remnant cholesterol levels exceeding 30 mg/dL, OR 8.93, 95% CI (2.99-26.62), p < 0.001. CONCLUSION: Remnant cholesterol is independently associated with hyperglycemia and diabetic nephropathy in individuals with type 1 diabetes.
