Insights

Hepatitis C virus (HCV) infection can lead to antibody disappearance (seroreversion) even in immunocompetent individuals. This finding is crucial for understanding transfusion inquiries and blood donor screening.

Area of Science:

  • Immunology
  • Virology
  • Hepatology

Background:

  • Hepatitis C virus (HCV) infection can resolve spontaneously, leading to antibody disappearance (seroreversion).
  • The frequency of HCV seroreversion in immunocompetent individuals remains debated.
  • Seroreversion has significant implications for blood transfusion safety and donor screening.

Purpose of the Study:

  • To investigate the long-term serological evolution of HCV infection in immunocompetent individuals.
  • To determine the rate of seroreversion in a cohort of multitransfused patients with resolved HCV infection.

Main Methods:

  • A longitudinal study followed 16 immunocompetent, multitransfused patients with confirmed anti-HCV antibodies.
  • Patients were monitored over an extended period without antiviral treatment.
  • HCV antibody status was assessed using EIA and Recombinant Immunoblot Assay (RIBA).

Main Results:

  • 12 patients (75%) remained anti-HCV positive with stable RIBA patterns after a mean follow-up of 7.6 years.
  • One patient (6.25%) showed complete seroreversion 6 years post-enrollment.
  • Three patients (18.75%) exhibited partial seroreversion over a mean of 16 years.

Conclusions:

  • HCV infection does not invariably result in a persistent antibody response, even in immunocompetent hosts.
  • The possibility of HCV seroreversion must be considered in transfusion-related investigations.
  • Findings highlight the complexity of HCV infection dynamics and serological markers.

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

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...
Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...

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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Blood Transfusion and Agglutination02:45

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
