Area of Science:

  • Hepatology
  • Infectious Diseases
  • Transfusion Medicine

Background:

  • Blood transfusions carry a risk of transmitting infectious agents.
  • Post-transfusion hepatitis (PTH) is a significant concern in transfusion medicine.
  • Identifying the causative agents and long-term outcomes of PTH is crucial for patient safety.

Purpose of the Study:

  • To investigate the incidence and etiological agents of post-transfusion hepatitis.
  • To determine the clinical presentation and outcomes of hepatitis following blood transfusions.
  • To assess the progression to chronic hepatitis in affected patients.

Main Methods:

  • A prospective study involving thirty patients who received blood or blood products.
  • Diagnosis of post-transfusion hepatitis based on clinical and laboratory findings.

  • Etiological classification of hepatitis (Hepatitis B vs. non-A, non-B hepatitis).
  • Percutaneous liver biopsy used to confirm chronic hepatitis.

    • Main Results:

    • Ten out of thirty patients (33.3%) were diagnosed with post-transfusion hepatitis.
    • The incidence rate was 15.75 cases per 1,000 units transfused.
    • Non-A, non-B hepatitis was diagnosed in 90% of cases, while 10% were Hepatitis B.
    • Two patients with non-A, non-B hepatitis developed chronic hepatitis, confirmed by liver biopsy.

    Conclusions:

    • Transfusion-associated hepatitis is a significant complication, predominantly caused by non-A, non-B hepatitis viruses.
    • A notable proportion of non-A, non-B hepatitis cases can lead to chronic liver disease.
    • Screening and prevention strategies for transfusion-transmitted hepatitis require continuous evaluation.
