Summary
A rare anti-Ge2 antibody was identified in a patient with a complex blood group (Ge:-2,-3, A1B Rh+). This antibody caused significant transfusion reactions, necessitating autotransfusion.
Area of Science:
- Immunohaematology
- Transfusion Medicine
- Blood Group Serology
Background:
- The identification of rare red blood cell antibodies is crucial for transfusion safety.
- The Ge blood group system antibodies are uncommon and can cause significant haemolytic transfusion reactions.
Observation:
- A case report detailing the first documented instance of anti-Ge2 in the country.
- The antibody was detected in a patient with a specific genotype (Ge:-2,-3) and blood type (A1B Rh+).
- The antibody exhibited reactivity in low ionic strength medium with a titre of 128 (IgG + IgM).
Findings:
- ABO compatible red blood cells, when labelled with 51Cr, demonstrated a significantly shortened lifespan.
- A high rate of haemolysis was observed, indicating a severe immune response against transfused red blood cells.
- The patient presented considerable challenges for transfusion management due to the presence of this antibody.
Implications:
- This case highlights the importance of extended antibody screening and characterization in patients with transfusion difficulties.
- Therapeutic autotransfusion was successfully employed as a management strategy, offering a potential solution for patients with rare antibodies.
- Further research into the prevalence and clinical significance of anti-Ge2 antibodies is warranted.
