Abstract
Serological safety is an integral part of overall safety for blood banks. The aim of the study was to determine the prevalence and specificities of red blood cell alloimmunization in multi-transfused patients with chronic kidney disease (CKD). A cross-sectional case-control study carried out at the University of Port Harcourt Teaching Hospital in which 186 patients with CKD were enrolled consecutively, 124 had received multiple transfusions (more than one unit of blood in one month, or at least 10 units within 3 months), while 62 had never been transfused. Antibody screen test was performed by the gel agglutination technique. RBC antibody identification was performed on the sera of those that tested positive to antibody screening test. Out of the 124 multi-transfused patients (total of 789 transfusions), 4 (3.2%) were alloimmunised. The alloimmunised patients received a higher mean number of 17.5 ± 12 blood units, compared to 6 ± 6 units by the non-alloimmunised multi-transfused patient (p= <0.001). Six clinically significant alloantibodies were identified with all of the alloimmunised patients forming more than one antibody. Anti-E was detected in all alloimmunised patients. The prevalence of RBC alloimmunisation in multi-transfused CKD patients was 3.2% with anti-E being the most frequently identified antibody.
Highlights
Blood transfusion is an integral part of the management of patients with chronic kidney disease (CKD) as severe anaemia is a feature of the late stages[1]
Study population The study population consisted of 186 adult patients with chronic kidney disease defined by patients who have glomerular filtration rate (GFR)
Blood transfusion may be life-saving in chronic kidney disease (CKD) as it promptly improves the oxygen-carrying capacity in patients with symptomatic anaemia
Summary
Blood transfusion is an integral part of the management of patients with chronic kidney disease (CKD) as severe anaemia is a feature of the late stages[1]. Objectives: The aim of the study was to determine the prevalence and specificities of red blood cell alloimmunization in multi-transfused patients with chronic kidney disease (CKD). Conclusion: The prevalence of RBC alloimmunisation in multi-transfused CKD patients was 3.2% with anti-E being the most frequently identified antibody.
