Treatment With Rituximab for Relapsed Warm Autoimmune Hemolytic Anemia

Presentation and Diagnosis

A 45-year-old Caucasian male was diagnosed with autoimmune hemolytic anemia (AIHA) in March 2015 during workup for a syncopal event. At presentation, his hemoglobin level was 6 g/dL and his platelet count was 120,000/µL. His medical history was significant for obesity, diabetes, and immune thrombocytopenia (ITP). His ITP was diagnosed in October 2004 and treated only with intravenous immunoglobulin (IVIg) in 2004, 2008, and 2014. He did not require treatment for chronic ITP.
