Post-transfusion non-A, non-B hepatitis in Finland: a prospective study
Scandinavian Journal of Clinical and Laboratory Investigation
|November 1, 1982
Summary
This study investigated post-transfusion non-A, non-B (NANB) hepatitis in Finnish patients undergoing heart surgery. The research found a 4.6% NANB hepatitis rate, highlighting the need for blood safety measures.
Area of Science:
- Hepatology
- Transfusion Medicine
- Infectious Diseases
Background:
- Post-transfusion hepatitis remains a significant concern in clinical practice.
- Non-A, non-B (NANB) hepatitis poses diagnostic challenges due to its varied presentation.
Purpose of the Study:
- To determine the incidence of post-transfusion NANB hepatitis in patients undergoing open-heart surgery in Finland.
- To assess the prevalence of NANB hepatitis and identify infective blood units.
Main Methods:
- Prospective follow-up of 65 patients receiving 652 blood units after open-heart surgery.
- Monitoring of transaminase levels for 6 months post-operation.
- Exclusion of known viral hepatitis etiologies (Hepatitis A, B, CMV, EBV) via serological testing.
Main Results:
- Three cases of post-transfusion NANB hepatitis were identified.
- All identified cases were subclinical and anicteric.
- The overall frequency of NANB hepatitis was 4.6%, with 0.5% of transfused units being infective.
Conclusions:
- Post-transfusion NANB hepatitis occurs at a notable frequency in cardiac surgery patients.
- Subclinical and anicteric presentations are common, underscoring the importance of sensitive diagnostic markers.
- Findings emphasize the ongoing need for robust blood screening and transfusion safety protocols.
