Transfusional therapy of hemodialyzed patient with anti-Cartwright antibodies: case report and review of the literature

BACKGROUND: Red cell Cartwright antigen (Yta) is very common in the general population therefore patients without red cell Cartwright antigen and with anti-Yta alloantibodies due to previous exposure to the antigen are rare. Report about clinical significance of Yta red cell alloantibodies in hemodialysis (HD) patients are scarce. CASE REPORT: We report a cirrhotic uremic patient with anti-Yta antibodies who received Yta positive red cells. No adverse reactions nor hemolysis were detected. CONCLUSIONS: We concluded that dialysis patients with anti-Yta antibodies could be safely transfused with blood from Cartwright positive donors.
