Insights

Hepatitis C virus (HCV) infection is transmitted within dialysis units. Longer time on maintenance hemodialysis significantly increases the risk of HCV acquisition in patients.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Nephrology

Background:

  • Hepatitis C virus (HCV) poses a significant risk to patients undergoing maintenance hemodialysis.
  • Understanding transmission dynamics and risk factors is crucial for infection control in dialysis settings.

Purpose of the Study:

  • To investigate the prevalence of HCV infection in a hemodialysis cohort.
  • To identify risk factors associated with HCV acquisition.
  • To determine the HCV genotypes prevalent in the studied population.

Main Methods:

  • Serological (anti-HCV) and virological (HCV-RNA) testing was performed on 66 patients.
  • Statistical analysis was used to evaluate risk factors like duration of hemodialysis, blood transfusions, transplantation, and prior hepatitis B infection.
  • HCV genotyping was conducted on positive samples.

Main Results:

  • Nine patients (13.6%) tested positive for anti-HCV, with all having detectable HCV-RNA.
  • Only the length of time on maintenance hemodialysis showed a significant association with HCV acquisition.
  • HCV genotypes 1 and 4 were identified, with genotype 4 being notably uncommon in Western Europe.

Conclusions:

  • Intra-unit transmission of HCV infection occurred within the studied maintenance hemodialysis group.
  • Prolonged duration of hemodialysis is a key risk factor for HCV infection.
  • The presence of rare HCV genotypes highlights potential unique transmission pathways.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

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...

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,...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
