A Retrospective Study of the Combination of Rituximab, Cyclophosphamide and Dexamethasone for the Treatment of Relapsed/Refractory Warm Antibody Autoimmune Hemolytic Anemia.

A Retrospective Study of the Combination of Rituximab, Cyclophosphamide and Dexamethasone for the Treatment of Relapsed/Refractory Warm Antibody Autoimmune Hemolytic Anemia. Acta Haematol. 2019 Oct 30;:1-6 Authors: Piatek CI, Bocian H, Algaze S, Weitz IC, O Apos Connell C, Liebman HA Abstract The combination of rituximab, cyclophosphamide, and dexamethasone (RCD) is highly effective in the treatment of warm autoimmune hemolytic anemia (WAIHA) associated with chronic lymphocytic leukemia (CLL). We treated a cohort of patients with relapsed/refractory WAIHA, without CLL, with RCD. The primary objective was to evaluate the overall response (OR) of RCD therapy. Complete response (CR) was defined as a hemoglobin (Hgb) ≥12 g/dL. Partial response (PR) was defined as Hgb 10-11.9 g/dL or ≥2 g/dL increase in Hgb. Sustained response was defined as Hgb ≥10 g/dL with no treatment changes. A total of 16 patients with relapsed/refractory WAIHA received RCD (7 primary WAIHA, 9 secondary WAIHA) for a median of 4 cycles (range: 2-6). The median pretreatment Hgb was 10.0 g/dL (range: 4.3-12.2). The median best Hgb achieved was 12.5 g/dL (range: 10.6-15.1) with a median of 2 cycles until best Hgb response. The OR was 94% (11 CR, 4 PR). Two immunocompromised patients were admitted for infections during RCD treatment. There were no deaths during the treatment or follow-up period. Following a response to RCD, 4 patients received noncorticosteroid imm...
