Summary
Diabetic dyslipoproteinaemia, characterized by abnormal lipid profiles, contributes to microvascular complications like nephropathy and retinopathy. Managing these lipoprotein abnormalities is crucial for reducing diabetes-related risks.
Area of Science:
- Endocrinology and Metabolism
- Cardiovascular Research
- Nephrology and Ophthalmology
Background:
- Microvascular complications (nephropathy, retinopathy) and accelerated atherosclerosis are significant risks in Type 1 and Type 2 diabetes mellitus.
- Key risk factors include age, diabetes duration, hyperglycemia, hypertension, smoking, inflammation, glycation, oxidative stress, and dyslipoproteinaemia.
- Dyslipoproteinaemia in diabetes extends beyond lipid levels to include lipoprotein subclass, composition, and functional alterations.
Purpose of the Study:
- To broaden the definition of lipid abnormalities in diabetes.
- To explore the role of dyslipoproteinaemia in diabetic microvascular complications.
- To highlight the potential of lipoprotein management in mitigating diabetes-related adverse outcomes.
Main Methods:
- Review and synthesis of current knowledge on diabetes dyslipoproteinaemia.
- Analysis of alterations across all lipoprotein classes (chylomicrons, VLDL, LDL, HDL, Lp(a)).
- Consideration of emerging evidence on lipoprotein-related genotypes and their impact on diabetic complications.
Main Results:
- Dyslipoproteinaemia is a common feature in diabetes, particularly with poor glycemic control or renal complications.
- Alterations involve lipid levels, lipoprotein subclasses, composition (glycation, oxidation), enzymes, and receptor interactions.
- Lipoprotein-related mechanisms may underlie damage to cardiovascular, renal, and ocular microvasculature.
Conclusions:
- Recognizing and treating lipoprotein-related risk factors is vital for early identification and management of high-risk diabetic patients.
- Further research, including intervention trials, is needed to guide optimal lipoprotein management strategies.
- Integrated lipoprotein management within comprehensive diabetes care can reduce the burden of microvascular complications and atherosclerosis.

01:15Diabetes: Symptoms, Diagnosis, and Complications
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:22Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
