Abstract

Introduction: Repeated blood transfusions can result in the production of alloantibodies against one or more red cell antigens, which complicates subsequent transfusions. Aims: The study was done to find incidence of various red cell alloantibodies; to determine the type of alloantibody; to identify the factors such as frequency of transfusion, splenectomy status, donor ethnicity and gender and their association with the development of antibody in repeatedly transfused patients.

Materials and methods: This study was carried out in Dept. of IHBT, Shree M. P. Shah Medical College, Jamnagar, Gujarat. Blood was taken from the patients of thalassemia major, sickle cell disease, chronic renal failure, post partum haemorrhage, aplastic anemia, Myelodysplastic syndrome with more than 10 red cell transfusions. The plasma/serum was used for antibody screening and antibody identification test. Three cell antibody screening was performed using antihuman globulin gel cards (ID-Card LISS/Coombs) and three cell panel (ID-DiaCell I, II, III-Asia). Those with positive antibody screening were analyzed further for antibody identification test using eleven cell panel (Set ID-Dia Panel).

Results: Antibody screening and identification was done in 2 consecutive set of samples (n = 300) which showed, nine (9) patients (3%) were alloimmunized. All repeatedly transfused patients had developed alloantibody before the starting of study period, no patient developed new alloantibody during study period.

Conclusions: Alloantibodies should be identified in repeatedly transfused patients and should be given corresponding antigen negative blood unit which will minimize the antibody mediated destruction of transfused red cells.

Keywords: Alloantibodies; antibody identification; antibody screening.
