Insights

Hepatitis C virus (HCV) infection is common in hemodialysis patients. Injection drug use is a significant independent risk factor for HCV RNA positivity in this population.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Epidemiology

Background:

  • Hepatitis C virus (HCV) infection is a leading cause of hepatitis in hemodialysis (HD) patients.
  • Understanding HCV prevalence and risk factors in this vulnerable group is crucial for public health.

Purpose of the Study:

  • To determine the prevalence of positive HCV RNA in patients undergoing chronic renal disease hemodialysis.
  • To investigate injection drug use as a potential emerging risk factor for HCV infection.

Main Methods:

  • A multicenter, cross-sectional study involving 325 patients on hemodialysis in Porto Alegre, Brazil.
  • Data collected via questionnaire, including duration of HD, blood transfusions, and drug use.
  • Laboratory tests included ALT, anti-HCV antibodies, and HCV RNA by PCR.

Main Results:

  • 68 out of 325 patients tested positive for HCV RNA.
  • Significant associations found between HCV RNA positivity and longer HD duration, prior blood transfusion, and injection drug use.
  • Logistic regression identified injection drug use (OR: 22.6) as a strong independent risk factor.

Conclusions:

  • Injection drug use is a significant independent risk factor for Hepatitis C virus infection in patients with chronic renal disease undergoing hemodialysis.
  • Findings highlight the need for targeted screening and prevention strategies in this high-risk population.

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

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...

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...

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...

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,...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...
