Insights

Vascular calcification (VC) affects 26% of dialysis patients, primarily linked to older age and diabetes mellitus (NIDDM). Dialysis duration and supplements showed no significant association in this study.

Area of Science:

  • Nephrology
  • Cardiovascular Medicine
  • Public Health

Background:

  • Vascular calcification (VC) is a common complication in chronic dialysis patients.
  • Known risk factors include dialysis duration, diabetes mellitus, aging, and mineral metabolism abnormalities.

Purpose of the Study:

  • To determine the prevalence of VC in a chronic dialysis population.
  • To identify specific risk factors associated with VC in this cohort.

Main Methods:

  • 129 chronic dialysis patients were assessed for VC using hand x-rays.
  • Patients were categorized as positive (PVC) or negative (NVC) for VC.
  • Demographic, clinical, and laboratory parameters were compared between groups.

Main Results:

  • VC was present in 26.35% of patients (34/129).
  • PVC patients were significantly older and had a higher incidence of non-insulin-dependent diabetes mellitus (NIDDM).
  • No significant differences were found in dialysis duration, calcium, phosphorus, calcium-phosphorus product, alkaline phosphatase, or intact parathyroid hormone levels.

Conclusions:

  • Older age and NIDDM are significant risk factors for VC in dialysis patients.
  • Dialysis duration and common supplements (calcium, vitamin D) were not significantly associated with VC in this medium-term dialysis population.
  • The role of these factors in long-term dialysis patients requires further investigation.

Hemodialysis I: Introduction01:25

Hemodialysis 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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Hemodialysis 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,...

Dialysis

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...

Diabetic 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...
