INTRODUCTION: We investigated short and long-term remission rates after splenectomy in patients with primary and secondary autoimmune hemolytic anemia (AIHA). METHODS: All adults who underwent splenectomy for primary or secondary AIHA at a single center (2004-2018) were retrospectively reviewed. Short-term response was determined at 30-day postoperatively and long-term at one year. Complete response was defined as hemoglobin > 10 g/dL without hemolysis, transfusions, or need for additional medical therapy for > 6 months. RESULTS: Short-term complete response was attained in 22 of 36 patients (61%), partial response in 3 (8%), no response in 11 (31%). The response rate at 1 year was complete in 14/36 (39%), partial in 14 (39%), and 8 non-response (22%). At last available follow-up (median 33.1 months (IQR 19-59), 16/37 patients had experienced a complete response (43%), 14 partial response (38%), 7 non-response (19%). 80% of partial responders with primary AIHA required maintenance therapy compared to 100% with secondary AIHA. CONCLUSION: Splenectomy is associated with short- and long-term improvement in anemia and hemolysis in the majority of patients with AIHA. Immunosuppressants remain important supplemental therapy.
