Summary
Patients with advanced chronic kidney disease (CKD) face high cardiovascular risk due to increased oxidative stress. Uremia, a condition in CKD, elevates oxidative stress, contributing to this risk beyond traditional factors.
Area of Science:
- Nephrology
- Cardiology
- Biochemistry
Background:
- Advanced chronic kidney disease (CKD) patients exhibit elevated cardiovascular risk.
- Traditional risk factors do not fully account for this increased risk.
- Oxidative stress is implicated as a non-traditional cardiovascular risk factor in CKD.
Purpose of the Study:
- To investigate the role of oxidative stress as a non-traditional cardiovascular risk factor in advanced chronic kidney disease.
- To elucidate the biological characteristics and contributing factors of uremic oxidative stress.
Main Methods:
- Review of laboratory findings demonstrating increased oxidative stress in uremia.
- Analysis of biomarkers associated with oxidative stress, including lipid peroxidation products and oxidized thiols.
- Examination of the multifactorial pathophysiology of increased oxidative stress in uremia.
Main Results:
- Uremia is unequivocally demonstrated to be an oxidative stress state.
- Uremic oxidative stress is characterized by increased lipid peroxidation and reactive aldehydes.
- Increased retention of oxidized thiols is observed in uremic patients.
Conclusions:
- Oxidative stress is a significant non-traditional cardiovascular risk factor in advanced chronic kidney disease.
- The loss of kidney function leads to the retention of oxidized solutes, contributing to uremic oxidative stress.
- Understanding uremic oxidative stress is crucial for managing cardiovascular risk in CKD patients.

01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
01:24Hemodialysis II: Procedure and Complications
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
01:27Dialysis
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:15Dialysis
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
01:25Hemodialysis III: Nursing Management
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this measurement...
01:00Cellular Injury I: Introduction
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...
