Insights

Occult hepatitis C infection (OHCI) is a risk for Iranian hemodialysis (HD) patients. This study found 3.03% of HD patients had OHCI, highlighting the need for sensitive diagnostic methods like PBMC testing.

Area of Science:

  • Hepatology
  • Virology
  • Nephrology

Background:

  • Occult hepatitis C infection (OHCI) is defined by Hepatitis C Virus RNA (HCV-RNA) presence in liver or peripheral blood mononuclear cells (PBMC) despite negative serology.
  • Chronic hemodialysis (HD) patients are a high-risk population for Hepatitis C Virus (HCV) infection.

Purpose of the Study:

  • To determine the prevalence of OHCI in Iranian patients undergoing chronic hemodialysis.
  • To assess the utility of PBMC testing for diagnosing OHCI in this cohort.

Main Methods:

  • A cross-sectional study involving 200 chronic HD patients with negative HCV antibody.
  • HCV RNA detection using Polymerase Chain Reaction (PCR) in both serum and PBMCs.

Main Results:

  • 2 patients (1%) were diagnosed with manifest hepatitis C infection (MHCI) based on positive serum HCV RNA.
  • 6 patients (3.03%) tested positive for HCV RNA in PBMCs, indicating OHCI.

Conclusions:

  • Chronic HD patients are susceptible to OHCI, not just manifest HCV infection.
  • PBMC analysis for HCV RNA is a sensitive method for detecting OHCI in HD patients.
  • Routine screening for OHCI may be warranted in high-risk HD populations.

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,...

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...

Hemodialysis 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...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
