Management of hemolytic transfusion reactions in a patient with chronic myelomonocytic leukemia and rare antibodies: A case report.

ABSTRACT: Delayed hemolytic transfusion reaction (DHTR) poses a significant challenge in patients receiving blood transfusions. This case report highlights the complexities of managing DHTR in a newly diagnosed chronic myelomonocytic leukemia (CMML) patient with clinically significant JKa and little c antibodies during induction chemotherapy. A 46-year-old woman with CMML-2 who presented for induction chemotherapy was found to have hemolytic anemia. Due to presence of JKa and little c antibodies, she required intensive monitoring and supportive care measures. The coexistence of JKa and little c antibodies complicates transfusion management and chemotherapy tolerance in CMML patients.
