Pure red cell aplasia (PRCA) and autoimmune hemolytic anemia (AIHA) post-hematopoietic stem cell transplantation (HSCT) are an unmet medical need with no established standard of care, significantly affecting the patient quality of life and posing a challenge for clinicians. The anti-CD38 IgG-kappa Daratumumab appears to be a safe and efficace treatment compared to prior drugs. Our study is a prospective monocentric investigation assessing the use of daratumumab in these complications following allo-HSCT. Here we describe our experience on six patients with a median age of 65 years. All treated patients, except one, who died because of sepsis during GVHD exacerbation, reached transfusion independence with erythropoietin suspension. Poor graft function remains a management challenge for clinicians and has a significant impact on the patient's quality of life. Currently, therapeutic options for PRCA and for the least common AIHA, appear ineffective, making it difficult to address the diverse needs of post-transplant patients. Although our data and those previously reported in the literature are preliminary, daratumumab prompts further reflection on its use in this setting of patients.
