His anti-A IgM/IgG titers reduced to 1:16/1:8 after CP [Figure 1]. Although his anti-A antibody titers were within target levels initially, he had a 4-fold increase in isoagglutinin titer on D + 7 along with increase in aminotransferase levels [Figure 1]. Due to the failure of reduction of titers, we switched to CP; four cycles of CP were performed from D + 10 to D + 13 [Figure 1].
