Unraveling the Complexity: A Case of Systemic Lupus Erythematosus, Warm Autoimmune Hemolytic Anemia, and Autoimmune Cholangitis

Systemic lupus erythematosus (SLE), warm autoimmune hemolytic anemia (WAIHA), and autoimmune cholangitis (AIC) are three distinct autoimmune conditions, each posing its own clinical challenges. The coexistence of these diseases in a single patient, however, is exceedingly rare and presents a complex diagnostic and therapeutic dilemma. SLE is an autoimmune disease that can cause a constellation of pathologies that affect various organs. WAIHA involves the premature destruction of red blood cells due to immunoglobulin (IgG) autoantibodies, leading to hemolytic anemia. AIC is characterized by features of both autoimmune hepatitis and cholestatic liver disease, which adds further complexity to this overlap syndrome. Herein presented is a case of a patient with simultaneous SLE, WAIHA, and AIC, highlighting the overlapping symptoms, diagnostic challenges, and the multifaceted approach to management. The case underscores the importance of a comprehensive, multidisciplinary approach to address the interplay of multiple autoimmune disorders, given the risk of therapeutic conflicts and disease progression.
