Insights

Patients with chronic kidney disease (CKD) and type 2 diabetes on hemodialysis show increased desialylated apolipoprotein-B-100 and immune complexes, accelerating atherosclerosis. These markers aid in diagnosing and predicting cardiovascular events in this high-risk population.

Area of Science:

  • Nephrology
  • Cardiology
  • Diabetology

Background:

  • Chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) are significant risk factors for cardiovascular disease.
  • Patients undergoing program hemodialysis often exhibit accelerated atherosclerosis.
  • The role of modified lipoproteins and immune complexes in this process requires further elucidation.

Purpose of the Study:

  • To determine the levels of desialylated apolipoprotein-B-100 (apoB-100) and lipoprotein-containing circulating immune complexes in hemodialysis patients with CKD and T2DM.
  • To assess the association of these markers with the extent of atherosclerosis and cardiovascular events.

Main Methods:

  • Study included 81 hemodialysis patients with CKD (36 with T2DM, 45 without).
  • Measured plasma levels of total cholesterol, triglycerides, desialylated apoB-100, and lipoprotein-containing immune complexes.
  • Assessed atherosclerosis using color duplex scan of brachiocephalic arteries to determine intima-medial thickness and stenosis.

Main Results:

  • Diabetic patients had higher total cholesterol and triglycerides (p<0.05).
  • Increased intima-medial thickness (13% higher) and prevalent plaques with stenosis (p<0.05) were observed in diabetic patients.
  • Significantly higher incidence of desialylated apoB-100 (46% increase) and lipoprotein-containing immune complexes (39% increase) in diabetic patients (p<0.05).
  • Diabetic patients with CKD experienced myocardial infarction 79% more often (p<0.05).

Conclusions:

  • Accelerated atherosclerosis in diabetic CKD patients on hemodialysis is linked to elevated modified low-density lipoprotein levels.
  • Desialylated apoB-100 and lipoprotein-containing immune complexes serve as potential diagnostic and prognostic markers for atherogenesis in this population.

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Lipid Digestion

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Structure of Lipids03:38

Structure of Lipids

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...
