[Lipoprotein and apoprotein changes in type-2 diabetes mellitus]

Area of Science:

• Endocrinology
• Cardiology
• Metabolic Disorders

Background:

• Diabetes mellitus type II is associated with significant alterations in lipid metabolism.
• Dyslipidemia in diabetes can increase the risk of cardiovascular complications, particularly ischemic heart disease.
• Understanding these lipid changes is vital for effective diabetes management.

Purpose of the Study:

• To investigate lipid metabolism indices in patients with diabetes mellitus type II.
• To compare lipid profiles in diabetic patients with and without ischemic heart disease.
• To determine if lipid profile normalization is a necessary component of diabetes compensation.

Main Methods:

• Lipid metabolism indices were monitored in 62 patients with diabetes mellitus type II and 20 healthy controls.
• Serum triglycerides, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), high-density lipoproteins (HDL), and cholesterol levels were analyzed.
• A comparative analysis was performed between diabetic patients with and without ischemic heart disease.

Main Results:

• Patients with diabetes mellitus type II exhibited elevated serum triglycerides, VLDL, and LDL, with decreased HDL and borderline high cholesterol.
• Diabetes compensation led to the normalization of these lipid indices.
• Diabetic patients with ischemic heart disease showed significantly lower HDL and higher VLDL and LDL compared to those without ischemic heart disease.

Conclusions:

• Diabetes compensation requires not only blood sugar normalization but also correction of lipid fraction abnormalities.
• Abnormal lipid profiles, particularly low HDL and high VLDL/LDL, are more pronounced in diabetic patients with ischemic heart disease.
• Monitoring and managing lipid metabolism is essential for comprehensive diabetes care and cardiovascular risk reduction.
