Background Autoimmune hemolytic anemia (AIHA) results in red blood cell destruction by auto‐antibodies directed against surface antigens and is rarely fatal. Here we describe a case of AIHA, refractory to both standard and experimental therapies, complicated by multiorgan failure, and rapidly leading to death. Case report and results A 65 year‐old man who presented with progressive dyspnea and jaundice was found to have hemolytic anemia. Diagnostic work‐up revealed a positive direct antiglobulin test and a strong pan‐reactive antibody in the plasma reacting to a titer of 1:1024 with strongest reactivity at 37 °C Coombs' phase with reagent anti‐IgG. The red cell eluate contained a pan‐agglutinin. The patient received multiple lines of treatment including glucocorticoids, intravenous immunoglobulin, rituximab, eculizumab, splenectomy and etoposide. Despite these interventions, he continued to experience brisk hemolysis and remained transfusion dependent. Repeat testing on day 16 demonstrated persistent high titer IgG auto‐antibodies, suggesting minimal suppressive effect of therapy. His course was complicated by acute renal and liver failure, venous thrombosis, and worsening coagulopathy, and he ultimately died from multiorgan failure on day 18. Conclusion Severe cases of AIHA can result in multiorgan failure and a fatal outcome. The rapid development of liver failure in this setting has been described in only few case reports to date, and represents an important complication for clinicians to be aware of when treating patients with AIHA.
