Erythrocyte alloantibodies in chronic kidney disease patients receiving packed red cell transfusions in Sanglah General Hospital, Denpasar

Introduction: In Chronic kidney disease (CKD) patients, as the consequences of the pathogenesis, anemia due to the failure of erythropoietin production requires Packed Red Cell (PRC) transfusion. The presence of alloantibodies in CKD patients who routinely require transfusion in Bali has never been evaluated. This study aims to determine the erythrocyte alloantibodies of CKD patients who received PRC transfusions in Sanglah Hospital. Methods: This study was a cross sectional descriptive study in adult CKD patients with history of PRC transfusion more than twice. Results: A total of 50 patients with Chronic Kidney Disease consisting of 31 men and 19 women, mostly 46-65 years old (60%) and the most blood group were blood group O (44%). There were 3 patients with positive antibody screening and identification results, 2 male patients (66.67%) and 1 female (33.33%). Two patients 46-65 years (66.67%) while 1 person 18-45 years (33.33%), with 2 person with blood group A (66.67%) and one person with blood group O (33.37% ). These three patients presented multiple alloantibodies in the form of anti-K, anti-Kpa, anti-Lua Conclusion: From the CKD patients who received PRC transfusions in Sanglah Hospital, ±6% formed alloantibodies. All of the alloantibodies formed were multiple alloantibodies, in the form of anti-K, anti-Kpa and Lua. Keywords: Chronic kidney disease, erythrocyte alloantibodies, packed red cell, transfusion
