Coexistence of Crohn’s Disease and Autoimmune Hemolytic Anemia

Coexistence of Crohn’s Disease (CD) and Autoimmune Hemolytic Anemia (AIHA) is uncommon, whereas concomitant cases of Ulcerative Colitis (UC) and AIHA have been relatively well-documented. This report reviews the English literature regarding the coexistence of CD and AIHA and discusses seven cases of concomitant CD and AIHA. The seven cases were predominantly male. There was no clear tendency of one disease preceding the other. Other complicating autoimmune diseases included Primary Sclerosing Cholangitis (PSC), which occurred in two of the seven cases.
